专利说明:

[001] [001] In some surgical operations, such as a gastrointestinal anastomosis, it may be desirable to fix one or more layers of tissue, cut through the attached tissue layers, and insert staples into the tissue layers to substantially seal the cut tissue layers together, near its cut ends. One of the instruments that can be used in such operations is a linear cut stapler. A linear cut stapler generally includes a first claw, a second claw, a lever to hold the first claw in relation to the second claw, an anvil associated with the first claw or the second claw, a staple cartridge associated with the claw opposite the anvil for staples and a movable trigger set in relation to the rest of the linear cut stapler. Typically, the first claw and the second claw can pivot in relation to each other to secure the fabric between the claws. The staples are arranged on the staple cartridge so that a portion of the firing assembly can act through the staple cartridge to drive the staples out of the staple cartridge, through the fabric, and against the anvil, also cutting at the same time the tissue captured between the staple cartridge and the staple anvil.
[002] [002] Although various types of surgical stapling instruments and associated components have been produced and used, it is believed that no one before the inventor (or inventors) has produced or used the invention described in the attached claims. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] [0033] The drawings are not intended to be limiting in any way and it is envisaged that various modalities of technology can be executed in a variety of other ways, including those not necessarily represented in the drawings. The drawings incorporated in the annex and forming a part of the specification illustrate various aspects of the present technology and, together with the description, serve to explain the principles of the technology; it is understood, however, that this technology is not limited precisely to the provisions shown. DETAILED DESCRIPTION
[0034] [0034] The following description of certain examples of the technology should not be used to limit its scope. Other examples, resources, aspects, modalities and advantages of the technology will become evident to those versed in the technique from the following description, which is given by way of illustration, one of the best ways contemplated to execute the technology. As will be understood, the technology described here is capable of other different and obvious aspects, all without deviating from the technology. Consequently, drawings and descriptions should be considered as illustrative and not restrictive in nature.
[0035] [0035] For clarity of description, the terms "proximal", "distal", "upper" and "lower" are defined here in relation to a human or robotic operator of the surgical instrument. The term "proximal" refers to the position of an element closer to the human or robotic operator of the surgical instrument and further away from the surgical end actuator of the surgical instrument. The term "distal" refers to the position of an element closer to the surgical end actuator of the surgical instrument and further away from the human or robotic operator of the surgical instrument. The terms "proximal", "distal", "upper" and "lower" are, therefore, relative terms and are not intended to unnecessarily limit the invention described herein. I. Exemplary linear cut stapler A. Overview of linear cut stapler features
[0036] [0036] Figure 1 shows an exemplary linear cut surgical stapler 100 that can be used for any suitable procedure, such as a gastrointestinal anastomosis. The linear cut stapler 100 includes a first portion 102 having a staple cartridge channel 122, a second portion 104 having an anvil channel 130, a staple cartridge assembly 150 that can selectively couple to cartridge channel 122 of the first portion 102, and a firing assembly 200. As will be described in more detail below, the first portion 102 and the staple cartridge assembly 150 can pivotally couple with the second portion 104 to form an end actuator 120 capable of gripping , cut and staple tissue captured between opposite halves of end actuator 120.
[0037] [0037] As best seen in Figures 3 to 6, the firing assembly 200 includes an actuation beam 202, a staple slide assembly 160 housed within the staple cartridge assembly 150, an actuator 204 (also called " trigger button ") and a pivot arm 206. The actuation beam 202 extends from a distal end 201 to a proximal end 203. The actuation beam 202 is slidably housed within the first portion
[0038] [0038] Although in the present example, the actuator 204 is configured to pivot for each side 116, 117 of the instrument 100 to drive the actuation beam 202, this is purely optional, since the actuator 204 can be slidably attached to the first 102 or the second portion 104 by any means evident to one skilled in the art, in view of the teachings of the present invention. In one example, actuator 204 may be closely associated with first side 116 or second side 117 so that actuator 204 may not pivot when end actuator 120 is in the fully closed position. In another example, there may be an actuator 204 positioned on both the first side 116 and the second side 117, so that the instrument 100 can include two actuators
[0039] [0039] As seen in Figure 3, the first portion 102 includes a first proximal structure 110, the staple cartridge channel 122 and a closing lever in the form of a locking lever
[0040] [0040] The first proximal structure 110 defines a channel that slidily houses the actuation beam 202 of the firing assembly 200. The proximal end 103 includes one or more side pins, or projections 111. The projections 111 are configured to receive grooves 115 of the second portion 104, in order to initially articulate the first and second portions 102, 104 in articulation. In the current example, the projections 111 are lifted from the rest of the first proximal structure 110 through a column 107, however this is merely optional. For example, projections 111 may include a single pin extending laterally through the side walls of the first proximal structure 110. Of course, any suitable initially articulated coupling means of the first portion 102 and the second portion 104 can be used as would be evident for one skilled in the art, in view of the teachings of the present invention.
[0041] [0041] As briefly mentioned above, the staple cartridge channel 122 extends distally from the first proximal structure 110. As seen in Figure 2, the staple cartridge channel 122 is sized to selectively engage and disengage from the set of staple cartridge 150. Staple cartridge channel 122 includes a bottom wall 126, and two opposite side walls 124 extending from opposite ends of the bottom wall 126. The walls 124, 126 are dimensioned to receive at least a portion of the staple cartridge assembly 150, as seen in Figure 4. In addition, side walls 124 include side projections extending inward (not shown)
[0042] [0042] As briefly mentioned above, locking lever 180 is pivotally coupled to the remainder of the first portion 102 by means of pivot pin 182. Locking lever 180 includes a proximal extension arm 184 and a distal locking body
[0043] [0043] The arm extending proximally 184 can be attached to an arm cover 186 to provide sufficient grip so that an operator can hold the arm 184 while he performs an appropriate procedure. The arm cover 186 can be coupled with the proximal extension arm 184 by any suitable means, as would be apparent to one skilled in the art in view of the teachings of the present invention. Alternatively, the cover of the arm 186 may be unitarily coupled with the arm extending proximally 184 or even omitted.
[0044] [0044] The distal locking body 188 includes a pair of hooks 189 (or "claws"). The distal lock body 188 also defines a corresponding pair of lock cutouts 185 located proximally to hooks 189. As will be described in more detail below, each hook 189 is sized to initially contact and then capture the respective lock projection 131 of the second portion 104 so that the distal lock body 188 can wrap at least a portion of each lock projection 131 to further pivot the second portion 104 towards the first portion 102. As will be described in more detail below, each latch cutout 185 is sized to receive a respective latch projection 131 when end actuator 120 is in the closed position with respect to first portion 102.
[0045] [0045] As best seen in Figures 4 to 6, the staple cartridge assembly 150 includes a cartridge body 152, a tray 154 and a plurality of staple triggers 168, each configured to drive a respective staple 171. The body cartridge number 152 defines a plurality of clip cavities 151, a slot 156 and coupling cutouts 140. The clip drivers
[0046] [0046] As mentioned above, the coupling cutouts 140 of the cartridge body 152 can be sized for a snap fit with the side projections (not shown) of the side walls 124 of the staple cartridge channel 122 so that an operator can selectively secure and separate the staple cartridge assembly 150 to the staple cartridge channel 122. The cartridge body 152 includes a distal nozzle 153. When the staple cartridge assembly 150 is properly coupled with the cartridge channel 122, the nozzle distal 153 can extend distally from cartridge channel 122 to provide an atraumatic tip.
[0047] [0047] Additionally, the cartridge body 152 includes a staple platform 158. The staple platform 158 partially defines staple cavities 151 so that the staple cavities 151 extend from inside the cartridge body 152 towards to an open end on the clamp platform
[0048] [0048] Tray 154 can include flexible arms 155. Flexible arms 155 can be configured to engage cartridge body 152 so that tray 154 can engage with cartridge body 152 in a snap-fit or snap-on relationship under pressure. Tray 154 can be coupled to cartridge body 152 after clamp drivers 168 and clamps 171 have been inserted into the respective clamp cavities 151. Tray 154 can therefore act as a floor for clamp drivers 168.
[0049] [0049] In the current example, the cartridge body 152 includes a casing of the slide assembly 170 located near the proximal end of the staple cartridge assembly 150. The housing of the slide assembly 170 is configured to initially house the assembly of staples staple slide 160 of firing assembly 200. The housing of slide assembly 170 includes a body 172 defining a cavity 174 having an opening facing it distally. The body 172 and the cavity 174 are dimensioned to accommodate a cutting member 164 of the slider assembly 160 before firing, therefore acting as a sheath for the cutting member 164. When fired, the cutting member 164 can come out of the casing of the slider assembly 170 through the cavity opening facing distally 174.
[0050] [0050] As best seen in Figures 7 and 8, the slide assembly 160 includes a slide body 162 and a cutting member
[0051] [0051] Slider body 162 also includes a plurality of cam surfaces 167 sized to slide longitudinally within respective elongated grooves (not shown) that pass through the staple cavities 151 of cartridge body 152. In particular, the surfaces of cam 167 are configured to engage and make cam contact against the inclined surfaces 169 of clamp actuators 168 within the clamp cavities 151 in order to actuate the clamp actuators 168 towards the clamp platform 158. The clamp actuators 168 then drive the corresponding clamps 171 through the clamp cavities 151 in the opposite direction to the clamp platform 158.
[0052] [0052] As mentioned above, the staple slide assembly 160 is configured to mate with the rest of the trigger assembly 200 when staple cartridge assembly 150 is properly coupled with staple cartridge channel 122. In the current example, the clamp slide assembly 160 of the firing assembly 200 is associated with the cartridge assembly 150 so that after the cartridge assembly 150 is used and discarded, the same is true of the clamp slide assembly 160. Therefore, when a assembly of additional cartridge 150 is loaded into the staple cartridge channel 122, a new staple slide assembly 160 will be present. However, this is purely optional. For example, the staple slide assembly 160 can be attached or attached to the rest of the firing assembly 200 so that the same staple slide assembly 160 can be used multiple times with multiple staple cartridge assemblies 150. In such examples , the cartridge body 152 would not need a slide assembly housing 170. The various ways in which the staple slide assembly 160 can be incorporated into the staple cartridge assembly 150, staple channel 122, or first proximal structure 110 will be apparent to those skilled in the art in view of the teachings of the present invention.
[0053] [0053] As shown in Figures 2 and 3, the second portion 104 of the instrument 100 includes a second proximal structure 114, anvil channel 130, lock projections 131 and an anvil surface arranged along and supported by the anvil channel 130 and shown in the form of anvil plate 134. The second proximal structure 114 extends from a proximal end defining grooves 115 in the anvil channel 130. In the present example, the second proximal structure 114 and the anvil channel 130 are integrally formed in order to define an elongated member of the anvil channel with a unitary construction. The second proximal structure 114 can be coupled to a grip cover 112 configured to provide sufficient grip so that an operator can control the instrument 100 while he performs a suitable procedure. The grip cover 112 and the second proximal structure 114 can be coupled with each other by any suitable means, as will be apparent to one skilled in the art, in view of the teachings of the present invention. Alternatively, the grip cover 112 can be unitarily coupled with the second proximal structure 114 or even omitted. The second proximal structure 114 can also define a channel configured to enable the portions of the firing assembly 200 to act in relation to the first portion 102 and the second portion 104 when the end actuator 120 is in the completely closed position (as shown in Figure 10D ).
[0054] [0054] The second portion 104 ends distally at a distal nozzle 139. The distal nozzle 153 can extend distally from the anvil channel 130 to provide an atraumatic tip. As shown in Figure 9, the proximal end of the anvil plate 134 defines a recess 179 sized to receive the casing of the slide assembly 170 when the first portion 102 and the second portion 104 are pivoted towards each other. As will be described in more detail below, the latch projections 131 extend laterally in the direction opposite to the anvil channel 130 and are sized to interact with the distal latch body 180 to drag the anvil plate 134 toward the cartridge assembly. clamp 150.
[0055] [0055] The anvil plate 134 defines a plurality of staple forming pockets 132 and a slit 133. The staple forming pockets 132 are positioned along the anvil plate 134 so that each staple forming pocket 132 fits align with a corresponding staple cavity 151 when the anvil channel 130 is pivoted towards the staple cartridge channel 122 to the fully closed position (as shown in Figures 1, 10D and 11A to B). Therefore, when the cam surfaces 167 of the sliding body 162 actuate the clamp actuators 168 according to the above description, the clamps 171 are driven through the clamp cavities 151 in the opposite direction to the clamp platform 158, through the fabric, and against a corresponding staple forming pocket 132 so that staples 171 change from a generic "U" shape to a generic "B" shape so that the fabric is properly stapled. Slit 133 is dimensioned to align laterally with slot 156 of the staple cartridge assembly 150 when the anvil channel 130 is pivoted to the fully closed position (as shown in Figures 1, 10D, 11A to 11B). Slit 133 is sized to receive a portion of the cutting member 164 slidingly as the slide assembly 160 is driven through the staple cartridge assembly 150 so that the cutting member 164 can cut the captured tissue between the anvil surface 134 and the staple platform 158 during exemplary use.
[0056] [0056] As best seen in Figure 9, the second portion 104 of the instrument 100 of the present example additionally includes a height adjustment mechanism for the clamp 136. The adjustment mechanism 136 is operationally coupled with the anvil plate 134, for example. example via one or more cam features (not shown), and includes a pair of user-engageable projections 138. Adjustment mechanism 136 is selectively movable with respect to anvil channel 130 between two or more longitudinal positions for raising or lowering the anvil plate 134 in relation to the anvil channel 130, and thus to adjust a gap distance (or "fabric gap") between the anvil plate 134 and the staple platform 158 when the first and second portion of the instrument 102 104 are coupled together in a completely closed position. A larger gap in the slot, and thus a higher staple height, can be provided to staple thicker fabrics. Similarly, a shorter span distance, and thus a lower staple height, can be provided for stapling fabrics of lesser thickness. It will be recognized that the height adjustment mechanism for clamp 136 is purely optional and can be omitted in other versions. In some versions of the instrument 100, the anvil surface, shown in the form of anvil plate 134, can be fixed in relation to the anvil channel
[0057] [0057] The linear cut surgical stapler 100 can be additionally configured and operable in accordance with one or more teachings of US patent No. 7,905,381, entitled "Surgical Stapling Instrument with Cutting Member Arrangement", granted on March 15, 2011 ; US Patent No. 7,954,686, entitled "Surgical Stapler with Apparatus for Adjusting Staple Height", issued June 7, 2011; US Patent No. 8,348,129, entitled "Surgical Stapler Having A Closure Mechanism", issued January 8, 2013; and in US Patent No. 8,789,740, entitled "Linear Cutting and Stapling Device with Selectively Disengageable Cutting Member", issued July 29, 2014. The description of each of these patent applications is incorporated herein by reference. B. Exemplary use of the linear cut stapler
[0058] [0058] Figures 10A to 11B show an exemplary use of the linear cut stapler 100. In particular, Figures 10A to 10D show an exemplary coupling of the first portion 102 with the second portion 104, and the articulation of the first portion 102 and the second portion 104 so that end actuator 120 transitions from an open position (Figure 10B) to a partially closed position (Figure 10C) and finally to a completely closed position (Figure 10D). Figures 11A and 11B show an exemplary shot of instrument 100 when end actuator 120 is in a completely closed position.
[0059] [0059] Figure 10A shows the first portion 102 completely separated from the second portion 204. In addition, the staple cartridge assembly 150 is suitably attached to the staple cartridge channel 122 according to the above description. At this point, during a procedure, such as during a gastrointestinal anastomosis, an operator may wish to place the tissue lumens on and pass through the distal nozzles 139, 153 of the second portion 104 and the cartridge assembly 150, respectively, so that the lumens of suitably associated with both the anvil plate 134 and the cartridge assembly 150. At this point, an operator can align the grooves 115 of the second portion 104 with the corresponding side projections 111 of the first portion 102 in the preparation of the initially hinged coupling of the first portion 102 with the second portion 104.
[0060] [0060] Then, as shown in Figure 10B, an operator can insert into the side projections 111 in corresponding grooves 115 so that the first portion 102 and the second portion 104 are hingedly coupled, but the end actuator 120 is in an open position. The first portion 102 and the second portion 104 can rotate with respect to each other about the axis defined by the side projections 111. At this point, the locking lever 180 is not in contact with any portion of the second portion 104. In addition, the lever locking mechanism 180 is in an open position so that the proximal extension arm 184 is hinged in the opposite direction of the first proximal structure 110.
[0061] [0061] Then, as shown in Figure 10C, an operator can initially pivot anvil channel 130 and anvil plate 134 toward cartridge channel 122 and staple cartridge assembly 150 and partially pivot the locking lever 180 so that hooks 189 initially contact lock projections 131. At this point, end actuator 120 is in the partially closed position. As is best shown between Figures 10C to 10D, after the hooks 189 initially come into contact with the lock projections 131, an operator can additionally rotate the proximal extension arm 184 towards the first proximal structure 110, causing the body distal latch 188 drive latch projections 131 along the surfaces of the distal latch body 188 toward the latch cutouts
[0062] [0062] Figures 11A to 11B show an exemplary shot of the instrument 100 with the end actuator 120 in the completely closed position. As best seen in Figure 11A, an operator can pivot actuator 204 to both sides 116, 117 of instrument 100. In the present example, actuator 204 has been pivoted to the second side 117 of instrument 100. Then, the operator can push the actuator 204 distally towards the end actuator 120 inside the slot 118, so that the actuation beam 202 and the slider 160 are fired, thus stapling and cutting the captured tissue between the stapling platform 158 and the anvil plate 134 according to the description above. Once the instrument 100 has been triggered, an operator can pull the actuator 204 proximally back to the position shown in Figure 11A, then rotate the actuator 204 back to the position shown in Figure
[0063] [0063] As described above, the locking lever 180 of the stapler 100 is movable between an open position (Figure 10B) in which the lever 180 allows halves of the stapler 102, 104 to be separated from each other, and a closed position in which lever 180 secures stapler 102 104 halves to each other. Specifically, the locking lever 180 of the half-cartridge 102 captures lock projections 131 of the half-anvil 104 when in the closed position to secure the halves of the stapler 102, 104 to each other. Locking lever 180 must be held in the open position while stapler halves 102, 204 are initially joined together to ensure that locking projections 131 can properly align with locking lever 180 and capture capabilities be received by them.
[0064] [0064] In some examples, it may be desirable to provide a linear cut stapler with a feature that holds the locking lever firmly in the open position while the stapler halves are assembled. The surgical stapler 300 described below includes such a feature in the form of a locking locking member 350. As described in greater detail below, in connection with Figures 13A through 13D, the locking locking member 350 is configured to act between a locking state. lever lock (Figure 13A) and a lever release state (Figure 13C) in response to stapler 300 anvil 304 being assembled with the half-cartridge
[0065] [0065] Figures 12 to 13D show another exemplary linear cut stapler 300 that is similar to the linear cut stapler 100 described above, except as otherwise described below. Stapler 300 includes a half-cartridge 302 and a half-anvil 304 configured to be releasably coupled to each other. Half-cartridge 302 includes an elongated cartridge channel member 306 with a distal channel portion 308 configured to receive a staple cartridge 310, which may be similar to the staple cartridge 150 described above. A proximal structure portion 312 of the cartridge channel member 306 is configured to slidably retain components of a trigger assembly (not shown), which may be similar to the trigger assembly 200 described above. As best seen in Figures 12 and 13A, the cartridge channel member 306 additionally includes a first pair of slits 314 formed in opposite side walls at a proximal end of the proximal frame portion 312, and a second pair of slits 316 formed in walls opposite sides in a medial portion of the cartridge channel member 306 near a distal end of the proximal structure portion
[0066] [0066] Half-cartridge 302 additionally includes a locking lever in the form of locking lever 318 hingedly coupled to the cartridge channel member 306 with a pivot pin 320 disposed in the medial portion of the cartridge channel member 306. Locking lever 318 includes an elongated lever arm 322 and a pair of opposing jaws 324 that extend distally from lever arm 322. As seen in Figure 13A, each jaw
[0067] [0067] As seen in Figure 12, the half-anvil 304 of the linear cut stapler 300 includes an elongated anvil channel member 334 that has a distal channel portion 336 and a proximal structure portion 338. The distal channel portion 336 supports an anvil surface shown in the form of anvil plate 340, which has a plurality of staple-forming pockets, and a distal tip member 342 that defines a distal end of the half-anvil
[0068] [0068] The anvil 304 additionally includes a pair of lock projections configured to be engaged by the locking lever 318 of the half-cartridge 302. In the present example, the lock projections are defined by opposite ends of a lock pin 346 which extends laterally through opposite side walls of the anvil channel member 334 at a medial location between the distal channel portion 336 and the proximal structure portion 338. In other examples, the lock projections of the stapler 300 may be similar to those lock projections 131 described above. As described below, the opposite ends of the lock pin 346 are configured to be received within medial slots 316 of the cartridge channel member 306. Although not shown, the cartridge channel member 306, the lock lever 318 and the member of anvil channel 334 may each include a cover similar to the covers 108, 112, 186 described above, to facilitate the gripping of the halves of the stapler 302, 304 by an operator. It will be recognized that several other stapler 100 features described above can also be incorporated into the stapler 300.
[0069] [0069] Similar to locking lever 180 described above, locking lever 318 is configured to pivot in relation to cartridge channel member 306 between an open position (Figures 12 to 13C) and a closed position (Figure 13D) to secure selectively half-anvil 304 against half-cartridge 302 to secure fabric between them. In the open position, the locking lever 318 allows the cartridge channel member 306 and the anvil channel member 334 to move relative to each other. In the closed position, the locking lever 318 captures the opposite ends of the locking pin 346 within the recesses 330 of the lever claws 324, thus securing the channel members 306, 334 to each other to prevent relative movement between the channel members. 306, 334. B. Linear cut stapler exemplary lock lock feature
[0070] [0070] As best seen in Figure 13A, the half-cartridge 302 of the stapler 300 additionally includes a locking member 350 hingedly coupled to the cartridge channel member 306 with a pivot pin 352. In the present example, the locking member 350 is positioned along the outside of a side wall of the medial portion of the cartridge channel member 306, and pivot pin 352 is in a position immediately distal to the medial slots 316. As described below, the locking member 350 is configured to engage claw 324 of locking lever 318. Although not shown, a second locking member 350 may be positioned along the outside of an opposite side wall of the locking channel member cartridge 306 and configured to engage the opposite jaw 324 of locking lever 318.
[0071] The locking member 350 of the present example is formed with a rounded V shape having a first leg 354, a second leg 356 and a cutout 358 defined between them. Locking member 350 is configured to pivot around pivot pin 352 between a locking state shown in Figures 13A and 13B, and a release state shown in Figures 13C and 13D. In addition, the locking member 350 is suitably disposed in the cartridge channel member 306, so that an open end of the cutout 358 is oriented towards and aligned with an open end of the respective medial slot 316 of the cartridge channel member 306 when the locking member 350 is in the locking state.
[0072] [0072] To initially assume the locking state, the locking lever 318 is placed in the open position so that the lever arm 322 is pivoted in the opposite direction to the proximal structure portion 312 of the cartridge channel member 306, and the lever claws 324 are pivoted in the opposite direction to the medial slots 316. In the locking state, an end surface of the first leg 354 of the locking member 350 contacts a side surface of the lateral protrusion 332 of the respective lever claw 324 and thus, it keeps the locking lever 318 in the open position. This prevents the lever claws 324 from obstructing the medial slots 316 of the cartridge channel member 306, so that the opposite ends of the lock pin 346 of the anvil 304 can be freely received within the medial slots 316, as stapler halves 302, 304 are joined together, as shown in Figure 13B.
[0073] [0073] As seen in Figures 12 to 13C, half-cartridge 302 and half-anvil 304 are joined by directing the proximal pivot pin 344 of half-anvil 304 into the proximal slits 314 of the cartridge channel member 306 and then pivoting the halves 302, 304 towards each other around the proximal pivot pin 344. As seen in Figure 13B, the lock pin 346 of the anvil 304 is directed into the medial slots 316 of the cartridge channel member 306, pass through the distal ends 326 of the lever claws 324 and into the cutout 358 of the locking member 350. Continuous pivoting of the halves of the stapler 302, 304 towards each other causes the locking pin 346 contacts a lateral surface of the first leg 354 of the locking member 350. This contact causes the locking member 350 to pivot in the opposite direction to the anvil 304, so that the first leg 354 disengages of the lateral protrusion 332 of the lever claw to 324, as seen in Figure 13C. This places the locking member 350 in a release state in which the locking member 350 is configured to pivot freely around its pivot pin 352, and the locking lever 318 is configured to pivot freely around its pivot pin. pivot 320.
[0074] [0074] As seen in Figures 13C and 13D, the operator can then pivot the lever arm 322 of the locking lever 318 towards the proximal frame portion 312 of the cartridge channel member 306 to engage the lock pin 346 with cam actuating surfaces 328 of the lever claws 324, and pull the lock pin 346 further into the medial slots 316 of the cartridge channel member 306 and into the claw recesses 330. Simultaneously, the locking member of lock 350 continues to pivot around its pivot pin 352 in order to rotate around lock pin 346, which remains disposed within cutout 358. Continuous pivoting of lock lever 318 places it in the closed position in which the lock pin 346 is captured within the claw recesses 330, so that the cartridge and anvil channel members 306, 334 are fixed in relation to each other. In the closed position of the lever 318, as seen in Figure 13D, the claws 324 capture a proximal side of the lock pin 346 and the locking member 350 captures an opposite distal side of the locking pin 346. In the present example, the locking member locking device 350 is spaced outwardly from the cartridge channel member 306, so that the lever jaw 324 is received in a space between the locking member 350 and a side wall of the cartridge channel member 306.
[0075] [0075] After a firing sequence is executed with the stapler 300, the locking lever 318 can be returned to the open position by pivoting the lever arm 322 in the opposite direction to the proximal structure portion 312 of the cartridge channel member 306. This movement releases the lock pin 346 of the lever claw 324 and simultaneously allows the locking member 350 pivot back towards the locking state in which the first leg 354 re-engages the side protrusion 332 of the lever claw 324, thus keeping locking lever 318 in the open position. In some examples, the locking lock member 350 can be propelled toward the locking state by a resilient member (not shown).
[0076] [0076] As described above, locking member 350 holds locking lever 318 in the open position and allows locking lever 318 to pivot towards the closed position only in response to locking pin 346 which is directed to the medial slots 316 of the cartridge channel member 306 to thus come into contact with the locking member 350. This avoids the undesirable scenario in which the locking lever 318 could pivot out of the open position prematurely, so that the tips distal 326 from the lever claws 324 would obstruct the medial slots 316 and prevent the medial slots 316 from receiving the lock pin 346. In addition, the locking lock member 350 in the locking state is configured to maintain locking lever 318 in the open position securely enough that the operator can still exert a force on the locking lever 318, for example, to facilitate the positioning of the half-cartridge 302 with respect to the anvil 304 and the fabric, without overcoming the locking member 350 and prematurely rotating the lever 318. This can prove to be advantageous particularly when the halves of the stapler 302, 304 are positioned in relation to the thick fabric to be stuck. III. Exemplary linear cut staplers with closing mechanism that provides mechanical advantage
[0077] [0077] As described above in connection with staplers 100, 300, an operator tightens the fabric positioned between the distal portions of the first and second halves of the stapler by pivoting the locking lever to a closed position. In some instances, particularly in surgical procedures involving thicker tissues, it may be difficult for the operator to apply the necessary closing force to the locking lever. This may require the operator to use both hands to close the locking lever in some cases. The exemplary staplers 400, 500 described below each include a closing mechanism that provides mechanical advantage to facilitate closing the locking lever, thus allowing the operator to close the locking lever with a single hand, even in procedures involving relatively thick fabric, thereby improving the ease of use of the 400, 500 stapler. A. Exemplary stapler with closing mechanism with first, second and third connections
[0078] [0078] Figures 14A to 14C show an exemplary surgical stapler 400 that is substantially similar to stapler 100 described above, except as otherwise described below. Stapler 400 includes a half-cartridge 402 and a half-anvil 404 configured to be releasably coupled to each other. Half-cartridge 402 includes an elongated cartridge channel member 406 that has a distal channel portion 408 and a proximal structure portion 410. Distal channel portion 408 is configured to receive a staple cartridge (not shown), which may be similar to the staple cartridge 150 described above. The proximal structure portion 410 is configured to slide the components of a trigger assembly (not shown), which may be similar to the trigger assembly 200 described above, slidably. The half-cartridge 402 additionally includes a closing lever 412 which is pivotally coupled to the cartridge channel member 406 with a pivot pin 414, and which is movable between the open and closed positions to reliably fix the halves of the stapler to each other 402, 404, similarly to the lock levers 180, 318 described above. As described in more detail below, the closing lever 412 is intended to actuate the components of a closing mechanism 430 that provides mechanical advantage by amplifying an input force applied to the closing lever 412 by an operator.
[0079] [0079] Stapler 400 half anvil 404 includes an elongated anvil channel member 416 that has a distal channel portion 418 and a proximal structure portion 420. The distal canal portion 418 supports an anvil surface (not shown) ) which has a plurality of staple forming pockets, and a distal tip member (not shown), which may be similar to the anvil plate 134 and tip member 139 described above. The anvil 404 additionally includes a pair of lock projections configured to be engaged by the closing mechanism 430 of half-cartridge 302. In the present example, the lock projections are defined by the opposite ends of a lock pin 422 extending laterally through the opposite side walls of a medial portion of the anvil channel member 416.
[0080] [0080] As seen in Figure 14A, the closing mechanism 430 of the stapler 400 includes a claw member 432 and a plurality of connections 434, 436, 438 that operationally couple claw member 432 to the closing lever 412. The clamping member jaw 432 is pivotally coupled to the distal portion of a side wall of the proximal structure portion 410 of the cartridge channel member 406 by a pivot pin 440. The jaw member 432 includes an elongated slot 442 configured to receive an end of the lock pin 422 when lever 412 is pivoted towards a closed position, as described below. Connections 434, 436, 438 are pivotally coupled to one another at a central pivot 444 that is configured to float transversely with respect to a longitudinal geometric axis of the cartridge channel member 406, towards the anvil 404 and at the opposite direction, as described in more detail below. The first connection 434 is pivotally coupled at a first end to a distal portion of the closing lever 412, and at a second end to the central pivot 444. The second connection 436 is pivotally coupled at a first end to a proximal end of the claw member 432, and at a second end to the central hinge 444. The third connection 438 is pivotally coupled at a first end to a side wall of the proximal structure portion 410 of the cartridge channel member 406, and at a second end to the central joint 444. This arrangement of the connections 434, 436, 438 provides the closing mechanism 430 with an "over center" configuration in which the first connection 434 remains positioned over the central joint 444 and displaced proximally to the claw member 432 during the entire operation of the closing mechanism 430, described below. Although the illustrated example only includes a closing mechanism 430, variations of the stapler 400 may include two closing mechanisms 430, with a closing mechanism 430 positioned on each side of the cartridge channel member 406.
[0081] [0081] Figures 14A to 14C show a closing sequence in which the closing lever 412 is pivoted from an open position to a closed position to actuate the connections 434, 436, 438 of the closing mechanism 430 and, thus, capture the lock pin 422 of half-anvil 404 with claw member 432 of half-cartridge 402. As seen in Figures 14A and 14B, closing lever 412 is pivoted from the open position towards the proximal structure portion 410 of the channel member cartridge 406, which causes the first link 434 to drive the central link 444 towards the anvil channel member 416. This central link movement 444 causes the third link 438 to pivot clockwise in relation to the channel member of cartridge 406 and the second connection 436 pivot counterclockwise with respect to the claw member 432. This movement of the second connection 436 causes claw member 432 to also pivot counterclockwise with respect to the channel member of cartridge 406, so that jaw member 432 pulls lock pin 422 of anvil 404 proximally into slot 442, as seen in Figure 14B. When the closing lever 412 reaches the closed position, as seen in Figure 14C, the lock pin 422 is captured at a proximal end of the claw slot 442 and the channel members 406, 416 are fixed in relation to each other. With lever 412 in the closed position, the first connection 434 is arranged at approximately 90 degrees for each of the second and third connections 436, 438, which are approximately aligned with each other in a collinear configuration. Closing lever 412 can be held in the closed position by an additional lock, a resilient member, or any other suitable mechanism that will be readily apparent to those skilled in the art.
[0082] [0082] The "over center" configuration of the closing mechanism 430 described above provides the mechanical advantage that facilitates the closing of lever 412 over cartridge channel member 406. In particular, an input force applied to lever 412 by an operator to close the lever 412 is amplified by the closing mechanism 430 and then applied as an increased output force on the lock pin 422 to pull the anvil
[0083] [0083] Figures 15A and 15B show another exemplary surgical stapler 500 that is substantially similar to stapler 400 described above, except as otherwise described below. The stapler 500 includes a half-cartridge 502 and a half-anvil 504 configured to be releasably coupled to each other. Half-cartridge 502 includes a cartridge channel member 506 configured to receive a staple cartridge (not shown) and a closing lever 512 coupled to cartridge channel member 506. Half-anvil 504 includes a channel member anvil 516 configured to support an anvil surface (not shown) that has a plurality of staple forming pockets. Half-cartridge 502 additionally includes a locking mechanism 530 that has a claw member 532 similar to claw member 432 described above, and a plurality of connections 534, 536 coupled together at a central hinge 538 and which operationally couple , the claw member 532 with the closing lever 512. The closing mechanism 530 is substantially similar in structure and function to the closing mechanism 430 described above, except as otherwise described below.
[0084] [0084] The closing mechanism 530 of the stapler 500 differs from the closing mechanism 430 of the stapler 400 in that the closing mechanism 530 includes only the first and second connections 534, 536. In place of the third connection 438, the central joint 538 of the closing mechanism 530 is configured to slide into a guide slot 540 formed in a side wall of the cartridge channel member 506. For example, the central hinge 538 may include a protrusion (not shown) that is received in a manner sliding inside the guide slot 540. The guide slot 540 of the present example extends along an arcuate path that is generally transversal to a longitudinal geometric axis of the cartridge channel member 506. The guide slot 540 works in a similar way to the third connection 438 of the closing mechanism 430 where the guide slot 540 limits the central hinge 538 from a proximal side. Similar to the closing mechanism 430, the closing mechanism 530 provides a mechanical advantage that facilitates the closing of the closing lever 512, particularly for fastening along the thick tissue. IV. Exemplary linear cutting stapler with ratchet closing mechanism
[0085] [0085] In some surgical procedures, it may be difficult for the operator of a surgical stapler that has first and second halves to completely secure them with one movement of the closing lever, as when attaching thicker tissues, for example. Consequently, it may be desirable to configure the closing mechanism of a surgical stapler to provide an initial coarse closure of the stapler halves, followed by a delicate final closing of the stapler halves. The exemplary surgical stapler 600 described below includes features that provide such functionality and thus improve ease of use for the operator.
[0086] [0086] Figures 16A to 16D show an exemplary surgical stapler 600 that is similar to stapler 100 described above, except as otherwise described below. Stapler 600 includes half-cartridge 602 and half-anvil 604. In the present example, the halves of stapler 602, 604 are coupled to each other in a non-releasable manner at their proximal ends via a pivot pin 605. In others For example, the halves of stapler 602, 604 can be configured to be releasably coupled to each other at their proximal ends, for example, in a similar manner to that described above in connection with staplers 100, 300.
[0087] [0087] Half-cartridge 602 includes an elongated cartridge channel member 606 that has a distal channel portion 608 and a proximal structure portion (not shown). The distal channel portion 608 is configured to receive a staple cartridge (not shown), which may be similar to the staple cartridge 150 described above. The proximal structure portion is covered by a first cover 610 and is configured to slide the components of a trigger assembly (not shown), which may be similar to the trigger assembly 200 described above, slidably. The half-cartridge 602 additionally includes a closing lever 612 that is pivotally coupled to the cartridge channel member 606 and is movable between an open position (Figure 16A) and a closed position (Figure 16C) to releasably fix the halves of the stapler 602, 604 to each other, similarly to the closing levers 180, 318, 412, 512 described above. As described in more detail below, the closing lever 612 is intended to actuate a ratchet closing mechanism 630 configured to pull the halves of the stapler 602, 604 together towards a completely stuck state.
[0088] [0088] In the present example, the closing lever 612 is propelled towards the open position by a resilient member shown in the form of a torsion spring 614 disposed between the closing lever 612 and the first cover 610. Additionally, the closing lever closing 612 is configured to be releasably locked in the closed position by snapping a projection 616 formed at a proximal end of the closing lever 612 with a receiving structure 618 formed on a facing surface of the first cover 610 The push-fit engagement of the projection 616 with the receiving structure 618 is sufficient to overcome the elastic force exerted by the torsion spring 614 when the closing lever 612 is pivoted to the closed position by an operator.
[0089] [0089] Stapler 600 half anvil 604 includes an elongated anvil channel member 620 that has a distal channel portion 622 and a proximal structure portion (not shown). The distal channel portion 622 supports an anvil plate (not shown) and a distal tip member (not shown), which may be similar to the anvil plate 134 and tip member 139 described above. The proximal structure portion of the anvil channel member 620 is covered by a second cover 624.
[0090] [0090] The ratchet closing mechanism 630 of the stapler 600 is defined by a gear structure 632 provided by a distal pivoting end of the closing lever 612, and a rack structure 634 coupled to the anvil 604 and projecting transversely. in the opposite direction to the same 604 in one direction with respect to half-cartridge 602. Gear frame 632 includes a first array of teeth 636 circumferentially spaced along at least one surface of gear structure 632 facing distally, and the frame of rack 634 includes a second array of teeth 638 disposed linearly along one side of the rack structure 634 distally facing. The rack frame 634 is positioned distally from the gear frame 632, so that the gear teeth 636 are positioned to engage the rack teeth 638.
[0091] [0091] As seen in Figures 16A and 16B, the halves of the stapler 602, 604 are configured to pivot towards each other around the proximal pivot pin 605 between a non-attached state (Figure 16A) and a partially attached state ( Figure 16B), during which the closing lever 612 remains stationary in the open position. The stapler halves 602, 604 pivot towards the partially stuck state of Figure 16B, the gear teeth 636 of the gear frame 632 slide over the rack teeth 638 of the rack structure 634 in a similar manner to the ratchet. In this regard, gear teeth 636 and / or rack teeth 638 can be swept in a suitable direction that allows teeth 636, 638 to pass through each other as the halves of stapler 602, 604 are pivoted towards each other. another, however, latches together to prevent the halves of the stapler 602, 604 from being pivoted in the opposite direction from each other. For example, gear teeth 636 can be swept in one direction from half-cartridge 602, and / or rack teeth 638 can be swept in one direction from half-anvil 604. The transition of halves from stapler 602, 604 from non-attached state (Figure 16A) to the partially attached state (Figure 16B) provides an initial coarse closure of the halves of the stapler 602, 604 to partially secure the tissue positioned between them.
[0092] [0092] Figure 16C shows the closing lever pivot
[0093] [0093] Figure 16D shows the reopening of the closing lever 612 when the operator wants to separate the halves of the stapler 602, 604 after the stapler 600 is fired. The operator pulls a proximal end of the closing lever 612 to disengage the snap-fit coupling between the lever projection 616 and the receiving frame 618. The operator then pivots lever 612 towards the open position so that the gear teeth 636 of gear frame 632 disengage rack teeth 638 from rack structure
[0094] [0094] The 630 ratchet locking mechanism configuration described above allows an operator to easily obtain a secure and adequate grip of the fabric with the stapler halves
