[0044] [0044] In the following detailed description, reference is made to the attached drawings that form part of this and in which it is shown by means of the illustration of specific realizations by which the invention can be practiced. These realizations are described in sufficient detail to enable a person skilled in the art to practice the invention, and it should be understood that other realizations or logical changes can be made without departing from the scope of the present invention. The following detailed description should therefore not be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.
[0045] [0045] This report refers to a surgical system (100) featuring a plurality of devices to provide minimally invasive access to a surgical site. In one embodiment, the surgical system (100) features a cone (300) and a surgical instrument (400). In one embodiment, the surgical system (100) features an dilator (200), a cone (300), and a surgical instrument (400).
[0046] [0046] With reference to FIG. 1, as an example, without limitation, a dilator (200) is provided to dilate body tissue. Body tissue can be any tissue located in the body, for example, without limitation, skin, fascia, adipose tissue, muscle, ligaments, peritoneum or the like. The dilation of body tissue increases the diameter of a lumen previously created in the tissue passing from the outside of a patient to a cavity in the body, for example, without limitation, the abdomen, chest, viscera, joint or the like. The dilator (200) has an elongated body (210), a tapered section (220), a proximal end (201), and a distal end (202).
[0047] [0047] The tapered section (220) is tapered and tapers from the distal end of the elongated body (210) to the distal end (202) of the dilator (200), thus providing an dilator tip (221). The dilator tip (221) is rounded or takes the shape of a semicircle, to prevent damage to body tissue and organs located in the body cavity. The dilator tip (221) facilitates the insertion of the distal end (202) into a lumen in the tissue. In one embodiment, the tapered section (220) allows a gradual dilation of the body tissue as the dilator (200) passes through the body tissue where the tapered section (220) circumferentially stretches or dilates the body tissue to a desired diameter, increasing , thus, the diameter of the lumen in the tissue. The dilation of the lumen in the tissue allows the passage of a surgical instrument (400) or a cone (300) coupled to a surgical instrument (400). In one embodiment, the tapered section (220) has a smooth surface.
[0048] [0048] The length of the tapered section (220) depends on the thickness of the body tissue.
[0049] [0049] In one embodiment, as shown in FIG. 1b, the dilator (200) has a circumferential indicator (222). The circumferential indicator (222) can indicate the circumference of the lumen in the tissue and / or the distance that the dilator (200) has penetrated the body tissue. The circumferential indicator (222) can extend circumferentially around the external surface of the dilator (200). The location of the circumferential indicator (222) can be varied and depends on the width or diameter of the surgical instrument (400) to be introduced through the lumen into the tissue. The circumferential indicator (222) can be positioned on the surface of the tapered section (220), on the non-tapered part (213) or the like. The circumferential indicator (222) can be a mark, symbol or line showing a distinguishable color, a projected part or a recessed part when compared to the dilator surface. The actual distance of the circumferential indicator (222) from the distal end (202) depends on the desired diameter of the lumen in the tissue, the length of the tapered part (220), the diameter of the non-tapered part (213) and / or the distance of desired penetration into body tissue. The circumference of the circumferential indicator (222) can be of any length, for example, without limitation, the circumference of the circumferential indicator can be 11 mm, 13 mm, 15 mm, 17 mm, 19 mm, 20 mm, 21 mm, 22 mm , 23 mm, 24 mm, 25 mm or the like. The circumferential indicator (222) can be positioned in a plane perpendicular to the longitudinal axis of the dilator (200). The circumferential indicator (222) can be positioned at a location on the dilator (200) that corresponds to the desired circumference of the circumferential indicator (222). For example, without limitation, where the desired circumference of the circumferential indicator (222) is 25 mm, the circumferential indicator (222) is positioned on the dilator (200) where the circumference of the cross section of the dilator (200) is 25 mm.
[0050] [0050] In one embodiment, as shown in FIGs. 1b-1f, the dilator (200) has dilator grooves (223) in order to reduce the amount of surface area of the dilator (200) that comes into contact with the lumen in the tissue, thereby reducing the friction between the dilator (200 ) and the lumen in the tissue created by the dilator (200) when penetrating the lumen in the tissue. The dilator grooves (223) are channels and can have any dimension that allows the reduction of the friction of the surface area of the dilator (200) and allows the expansion of a lumen in the tissue. The width of the dilator grooves (223) affects the amount of friction between the dilator (200) and the lumen in the tissue where increasing the width of the dilator groove (223) increases the friction between the dilator (200) and the lumen in the fabric.
[0051] [0051] In one embodiment, the dilator (200) has dilator protrusions (not shown) in order to reduce the amount of surface area of the dilator (200) that comes in contact with the lumen in the tissue, thereby reducing the friction between the dilator
[0052] [0052] In one embodiment, the elongated body (210) has a handle (211), a tapered part (212), and a non-tapered part (213). The handle (211) is positioned at the proximal end (201) of the dilator (200). In a preferred embodiment, the elongated body (210) is configured to provide and facilitate proper positioning of the handle (211) and indicates to a user the orientation of the handle (211) in relation to the tapered section (220). The tapered part (212) is substantially in frustoconical shape. In some cases, the non-tapered part is pushed through the entire length of the lumen in the tissue. The tapered part (212) allows the lumen in the tissue to be dilated again when the dilator is recovered by being pulled in the reverse direction through the lumen in the tissue. In one embodiment, the tapered part (212) and the handle (211) allow the dilator (200) to be lighter and more easily maneuverable. Here, the proximal end of the tapered part (212) couples the handle (211) and the distal end of the tapered part (212) couples the proximal end of the tapered section (220).
[0053] [0053] In one embodiment, the elongated body (210) has a non-tapered part (213) that extends between the tapered section (220) and the tapered part (212). Here, the proximal end of the tapered part (212) engages the handle (211) and the distal end of the tapered part (212) engages the non-tapered part (213). The distal end of the non-tapered part (213) couples the tapered section (220) and the proximal end of the non-tapered part (213) couples the tapered part (212) of the dilator (200). The non-tapered part (213) maintains the dilation of the body tissue.
[0054] [0054] In one embodiment, as shown in FIG. 1, the elongated body (210) has a button (214) to prevent hurting the user's palm. The button engages the proximal end of the elongated body (210). Although the diameter of the button (214) can have any dimension that allows for proper use, the diameter of the button (214) is preferably the same diameter as the non-tapered part (213).
[0055] [0055] Although the dimensions of the dilator (200) depend on the desired diameter of the lumen in the tissue, the thickness of the body tissue into which the lumen in the tissue passes, the cavity to be penetrated or the type of surgical instrument (400) to be passed through the lumen in the tissue, the length of the dilator (200) is any length that allows for proper use. For example, without limitation, the length of the dilator (200) is preferably 11.00 inches to 17.00 inches, the length of the elongated body (210) is preferably 5.00 inches to 11.00 inches, the length of the handle (211) is preferably 2.00 inches to 8.00 inches, the length of the tapered section (220) is 1.00 inches to 6.50 inches, the length of the tapered portion (212) is preferably 1, 00 inches to 3.00 inches, the length of the non-tapered part (213) is preferably 1.00 inches to 5.00 inches, the length of the largest diameter of the dilator tip (221) is preferably 0.12 inches to 0.38 inches, and the taper angle of the tapered section (220) is preferably 4 degrees to 25 degrees.
[0056] [0056] In one embodiment, the dilator (200) has an external helical thread that extends around the surface of the tapered section (220) from the proximal end of the tapered section (220) to the distal end (202) of the dilator (200). In one embodiment, the dilator may have a plurality of discrete threads. The dilator (200) can be used as a corkscrew to dilate body tissue and prevent the dilator (200) from diving into the surgical site by rotating the dilator (200) to penetrate and dilate the lumen in the tissue.
[0057] [0057] In one embodiment, as shown in FIG. 1b, the dilator may have at least one guide passage (231), a first opening (232), and a second opening (233) for guiding a suture and / or suture-passing device (650). The external surface of the dilator (200) can have the first opening (232) defining an orifice and the second opening (233) defining an orifice. The first opening (232) and the second opening (233) can be positioned anywhere on the dilator (200), for example, without limitation, the first opening (232) can be positioned on the tapered part (212), on the non tapered (213), in the tapered section (220) or the like, and the second opening (233) can be positioned anywhere on the dilator (200), for example, without limitation, the second opening (233) can be positioned in the tapered (212), in the non-tapered part (213), in the tapered section (220) or similar. The guide passage (231) can extend between the first opening (232) and the second opening (233) through the dilator (200). As shown in FIG. 1c, the guide passage (231) can extend at an angle α, from the vertical longitudinal plane (P) of the dilator (200). The angle α can affect the depth of the suture in the fascia. For example, without limitation, a larger α angle will make the suture depth in the fascia greater and a smaller α angle will make the suture depth in the fascia smaller. The guide passage (231) can extend at an angle Ω, starting from the horizontal longitudinal plane (P) of the dilator (200). The angle Ω can affect the depth of the suture in the fascia.
[0058] [0058] In one embodiment, the guide passage (231) can extend longitudinally or parallel to the longitudinal axis of the dilator (200). In one embodiment, the guide passage (231) may have a right or left orientation. A guide passage (231) with a right orientation allows the user to insert the suture by passing the device (650) through the guide passage (231) using the right hand.
[0059] [0059] In one embodiment, the second opening (232) is positioned in relation to the circumferential indicator (222) in order to allow the suture passage device (650) to pass through the cross section of the plane, in which the circumferential indicator it is positioned outside the circumference of the circumferential indicator (222). For example, without limitation, the second opening (232) can be positioned close to the circumferential indicator (222).
[0060] [0060] In one embodiment, the angle α of the guide passage (231) and the distance between the second opening (233) and the circumferential indicator (222) are coordinated so as to allow the suture passage device (650) to pass through the cross section of the plane, on which the circumferential indicator (222) is positioned, at a desired distance outside the circumference of the circumferential indicator (222). This ensures that the suture pulls the lumen in the tissue to close it without tearing, bundling or damaging the fascia. The angle α of the guide passage (231) can be in the ranges above 0o and 60o and the distance between the second opening (233) and the circumferential indicator (222) can be in the ranges of 0 and 150 mm. For example, without limitation, when the circumference of the circumferential indicator (222) is 21 mm and the desired distance from the suture insertion point is 10 mm outside the circumference of the circumferential indicator (222), the distance between the second opening ( 233) and the circumferential indicator (222) is within the range of 0 mm - 150 mm and the angle α of the guide passage (231) is within the range of 0 ° - 60 ° As another example, without limitation, when the circumference of the indicator circumferential (222) is 25 mm and the desired distance from the suture insertion point is 10 mm outside the circumference of the circumferential indicator (222), the distance between the second opening (233) and the circumferential indicator (222) is at range 0 mm - 150 mm and the angle α of the guide passage (231) is within the range 0 ° - 60 °.
[0061] [0061] In one embodiment, as shown in FIG. 1f, the dilator (200) may have an interior insertion indicator (241) to indicate the radial position of the second opening (233) of the guide passage (231). In one embodiment, the interior insertion indicator (241) indicates the radial position on the dilator (200) where the suture-passing device (650) will exit through the second opening (233) and thus the radial position on the surface interior of the lumen in the tissue from which the suture will be inserted into the fascia. The interior insertion indicator (241) can be a mark, symbol, line, a protruding part when compared to the dilator surface (200), a recessed part when compared to the dilator surface (200) or multiple of the representations mentioned above. In one embodiment, the interior insertion indicator (241) may have a distinguishable color.
[0062] [0062] In one embodiment, the dilator (200) may have an outer insertion indicator (242) to indicate the radial position of the first opening (232) of the guide passage (231). In one embodiment, the outer insertion indicator (242) indicates the radial position on the dilator (200) where the suture-passing device (650) will enter through the first opening (232) and, thus, allows the surgeon to determine the radial position inside the lumen surface in the tissue from where the suture will be inserted into the fascia. The outer insertion indicator (242) can be a mark, symbol, line, a protruding part when compared to the dilator surface (200), a recessed part when compared to the dilator surface (200) or multiple of the representations mentioned above. In one embodiment, the outer insertion indicator (242) may have a distinguishable color. When the dilator (200) has more than one outer insertion indicator (242), an outer insertion indicator (242) can be represented differently from another outer insertion indicator (242), for example, without limitation, where the dilator (200) has two external insertion indicators (242), the first external insertion indicator (242) can be represented as a single line and the second external insertion indicator (242) can be represented by a double line.
[0063] [0063] In one embodiment, the surgical instrument (400) can be any instrument that passes through the body tissue, for example, without limitation, a surgical stapling device, a retractor, a joint dissector or the like. The surgical instrument (400) can be of any size that allows proper use.
[0064] [0064] The handle assembly (420) is connected to the cartridge assembly (440) by the elongated body (430). The handle assembly (420) has an actuating lever (422) to activate the surgical stapling device which implements a circular arrangement of staples and cuts and removes a circularly shaped piece of tissue. The assembly of incude
[0065] [0065] In one embodiment, the surgical system (100) features a cone (300) for the introduction of a surgical instrument (400) through body tissue by dilating the surrounding body tissue, thus minimizing the amount of trauma caused to the body tissue surrounding. In one embodiment, the cone (300) can minimize trauma by any suitable means, for example, without limitation, the cone (300) allows a user to locate the orientation of a lumen in the tissue in the body tissue and navigate the surgical instrument ( 400) through the lumen in the tissue while causing minimal damage to the surrounding tissue. In one embodiment, when removed, the cone (300), having enlarged the surrounding tissues instead of cutting them, allows the surrounding tissue and the lumen to be constricted in some way and regain part of its original shape in this way reducing the risk of hernia formation and / or reducing the need for more sutures to close the lumen in the tissue. In one embodiment, the cone (300) allows a user to dilate a lumen in the previously dilated tissue that has been constricted while causing minimal damage to the surrounding body tissue.
[0066] [0066] With reference to FIGS. 4a-4c and 5, the cone (300) has a body (310), a cone tip (320), a longitudinally extending axial hole (330), and an outer surface (303). The proximal end (301) of the cone (300) engages the distal end (402) of the surgical instrument (400).
[0067] [0067] The body (310) is tapered and is preferably tapered from the proximal end (301) to the distal end (302), thus providing a cone tip (320). The cone tip (320) is rounded or takes the shape of a semicircle, to avoid damage to body tissue and organs located in the body cavity. In one embodiment, the cone tip (320) facilitates the insertion of the distal end (302) into a lumen previously created in the tissue. The lumen in the tissue can be created by a trocar or similar instrument. Here, the cone (300) allows a gradual dilation of the body tissue as the cone (310) passes through the body tissue where the cone (300) circumferentially stretches or dilates the body tissue to a desired diameter, thereby increasing the diameter of the lumen in the tissue and allowing the instrument to more easily enter a visceral body or cavity. In one embodiment, the tapered configuration facilitates the insertion of the distal end (302) into a previously dilated lumen in the tissue.
[0068] [0068] The longitudinally extending axial hole (330) receives the incude retainer (451) co-axially, thus allowing the proximal end (301) of the cone (300) to engage the distal end (402) of the surgical instrument (400). In one embodiment, the axial hole (330) receives the incude retainer (451), thus preventing lateral movement or dislodging of the cone (300). Although any dimensions of the axial orifice (330) are contemplated, the dimensions preferably correspond to the dimensions of the incude retainer (451) used with the cone (300). For example, without limitation, the tolerance between the incude retainer (451) and the axial orifice (330) is zero where the axial orifice (330) is designed to match the incude retainer (451) or greater than zero for allow the cone (300) to be released from the incude retainer (451). In one embodiment, the depth of the axial hole (330) is less than the length of the incude retainer (451) thus allowing the incude retainer to push the cone (300) out of the surgical instrument (400) when the incude retainer is in the extended position.
[0069] [0069] In one embodiment, the proximal end (301) of the cone (300) has a proximal cavity (340) and a cavity surface (341), where the outer edge of the cavity surface (341) engages the outer edge of the distal end (402) of the surgical instrument (400). The proximal cavity (340) prevents the “peristrip” from coming into contact with the proximal end (301) of the cone (300) and, in turn, from getting caught in the proximal end (301) of the cone (300) where the cone (300) detaches from the distal end (402) of the surgical instrument (400). In one embodiment, the proximal end
[0070] [0070] In one embodiment, where the incude (452) is one-piece with the surgical stapling device and the surgical instrument (400) is in the closed position, the proximal cavity (340) is designed to match the distal end of the incude (452).
[0071] [0071] In one embodiment, the cone (300) features a choker (360) to prevent lateral movement and / or dislodgment of the cone (300) when the cone (300) engages the proximal end (401) of the surgical instrument (400 ). The choker (360) provides a choker cavity (370) that receives the distal end (402) of the surgical instrument (400). The choker (360) is designed to match the distal end (402) of the surgical instrument (400), thus preventing lateral movement and / or dislodging of the cone (300). In this embodiment, the annular rim (350) of the cone (300) engages the distal end (402) of the surgical instrument (400), thus preventing the “peristrip” from getting stuck in the cone (300) when the cone (300) ) detaches from the surgical instrument (400). Although any dimensions of the choker (360) are contemplated, the choker (360) preferably has a height between 0.25 inches and 2.00 inches and a width extending from an outer point on the choker (360) to an outer point on the side opposite of the choker (360) between 0.60 inches and 1.50 inches, and a thickness between 0.03 inches and 0.16 inches. In one embodiment, the incude retainer (451) is longer than the axial hole (330). Here, the choker (360) preferably has a height between 1/4 inch and 2 inches. In one embodiment, the height of the choker (360) is the length of the incude retainer (451) fully extended minus the depth of the axial hole (330).
[0072] [0072] Although the dimensions of the cone (300) depend on the desired diameter of the lumen in the tissue, the thickness of the body tissue into which the lumen in the tissue passes, the cavity to be penetrated or the type of surgical instrument (400) to be passed through the lumen in the tissue, the length of the cone (300) is approximately 1.00 inches to 6.50 inches, the depth of the proximal cavity (340) is approximately 0.16 inches to 0.34 inches, the width of the rim (350) is approximately 0.02 to 0.05 inches, and the height of the choker (360) is approximately 0.25 to 2.00 inches.
[0073] [0073] In one embodiment, the cone (300) has cone grooves (375) to reduce the size of the surface area of the cone (300) that comes in contact with the lumen in the fabric,
[0074] [0074] In one embodiment, the cone (300) has cone protuberances (376) to reduce the size of the surface area of the cone (300) that comes into contact with the lumen in the fabric, thereby reducing the friction between the cone (300) and the lumen in the tissue created by the dilator (200) penetrating the lumen in the tissue. In one embodiment, the cone protuberances (376) can create a force to move the cone (300) inward or to shape the lumen in the fabric. The cone protuberances (376) are raised ribs and can have any dimension that allows the reduction of the friction of the surface area of the cone (300) and allows the expansion of a lumen in the tissue. The width of the cone protuberances (376) affects the amount of friction between the cone (300) and the lumen in the fabric. In one embodiment, the cone protuberances (376) are positioned on the surface of the tapered section (220). In one embodiment, the cone protuberances (376) are positioned on the surface of the tapered section (220) and the non-tapered part (213). The cone protuberances (376) can extend partly or the entire length of the tapered section (220) from the proximal end to the distal end of the tapered section (220) and can be straight or spiral. The cone protuberances (376) can have any cross-sectional shape, for example, without limitation, those shown in FIGS. 4e,
[0075] [0075] In one embodiment, the cone (300) has a fixing device (380) to prevent longitudinal movement of the cone (300) in relation to the elongated body (430).
[0076] [0076] In one embodiment, the fixing device (380) is a clip incorporated in the axial hole (330). Here, the width of the axial hole (330) is slightly less than the width of the incude retainer (451) causing the clip to engage the incude retainer (451) when the incude retainer (451) passes through the axial orifice ( 330), thus preventing the longitudinal movement of the cone (300).
[0077] [0077] In a preferred embodiment, the system has a protective cover (500) to prevent contamination, seeding, infection or the like, resulting from a surgical procedure. With reference to FIGS. 2a-3, the protective cap (500) has an elongated tubular body (510) defining an elongated lumen (520) and has a proximal end (501) and a distal end (502). The surgical instrument (400) passes through the lumen of the protective cover (500), thus preventing the surgical instrument (400)
[0078] [0078] In one embodiment, the protective cap (500) features a sheath clamp to attach the protective cap (500) to the surgical instrument, thereby preventing the protective cap (500) from moving under the surgical instrument ( 400). Although the sheath clamp can be any suitable means for attaching the protective cap (500) to the surgical instrument (400), the sheath clamp is preferably a reinforced section that is coupled with the incude retainer (451), thereby fixing , the protective cover (500) on the surgical instrument (400). The reinforced section can be any suitable means that allows the protective cap to be attached to the surgical instrument, for example, without limitation, a section with increased thickness, a ring incorporated in the sheath clamp and sized to receive a part of the incude retainer (451) or the like.
[0079] [0079] As an example, the method of using the surgical system (100), where as an example, without limitation, a surgical stapling device will be described as the surgical instrument (400). An incision is made in the body tissue. A trocar or similar instrument is inserted into the incision and through the body tissue, thereby creating a lumen in the tissue. The trocar is removed from the lumen in the tissue and the dilator tip (221) is inserted into the lumen in the tissue, thereby expanding the lumen in the tissue. The dilator (200) penetrates to a desired depth in the body tissue indicated by the circumferential indicator (222), thus stretching or dilating the body tissue to a certain diameter sufficient to receive the diameter of the desired surgical instrument (400) being used and increasing the diameter of the lumen in the tissue. The lumen in the tissue allows the passage of a surgical stapling device. The elongated body (430) of the surgical stapling device passes through the lumen (520) of the protective cover (500) until the distal end (502) of the protective cover (500) is substantially on the same plane as the distal end (402) of the device surgical stapling or slightly beyond the distal end (402).
[0080] [0080] A fixing filament (382) is passed through the passage (381) of the cone (300).
[0081] [0081] The tip of the cone (300) attached to the surgical stapling device is inserted into the lumen in the tissue. The cone tip (300) allows the user to find the orientation of the lumen in the tissue and navigate the cone (300), the surgical stapling device, and the protection (500) through the lumen in the tissue by expanding said lumen in the tissue. When the cone (300), the guard (500), and the surgical stapling device reach a desired position in the body cavity, the force exerted on the two ends (383, 384) of the surgical filaments is removed and the incude retainer (451) is removed. The cone (300) leaves or is removed from the surgical stapling device and rests on the cavity in the body with the two ends of the fixation filament (383, 384) remaining external to the patient. The protective cover (500) remains around the surgical instrument (400) in the lumen in the tissue, thus preventing the surgical stapling device from coming into contact and contaminating the lumen in the tissue.
[0082] [0082] In one embodiment, as shown in FIG. 5, the cone (300) has a recovery device (390) for recovering the cone (300) from a cavity in the body by pulling the cone (300) through the lumen in the tissue. In one embodiment, the recovery device (390) is a recovery filament, where the recovery filament is preferably the same filament as the fixing filament (382). However, all suitable recovery devices (390) are provided, for example, without limitation, a claw, a needle, a clamp or the like. The recovery jaw can be a jaw with a peg positioned perpendicular to the longitudinal axis of the jaw. The pin passes through the passage (381) in the cone (300) and the cone (300) is pulled through the lumen in the fabric.
[0083] [0083] At the end of the use of the surgical stapling device, the surgical stapling device with the coupled incude (452) is recovered through the lumen (520) of the protective cover (500), and thus leaves the lumen in the tissue without contaminating or sow infection.
[0084] [0084] In one embodiment, the surgical system (100) features a closure system (600) to close a wound. In one embodiment, the closing system (600)
[0085] [0085] In one embodiment, as shown in FIGS. 7 & 8, the cone (300) may have stabilization holes (620) for receiving the stabilization tool (610). The stabilization holes (620) can allow the cone (300) to be secured, manipulated, stabilized or controlled during the closure of an injury. The stabilization holes (620) can allow the cone (300) to be secured, for example, without limitation, by receiving the tips of the stabilization tool (610). The stabilization holes (620) can be positioned anywhere in the cone (300), for example, without limitation, in the choker (360), in the body (310) or the like. The stabilization holes (620) can penetrate through the entire thickness of the choker (360) or the stabilization holes (620) can be a cavity that partially penetrates the thickness of the choker (360).
[0086] [0086] In one embodiment, as shown in FIGS. 11 & 12, the cone (300) can have stabilization cavities (626) to receive the user's fingers. The stabilization cavities (626) can allow the cone (300) to be secured, manipulated, stabilized or controlled during the closure of a wound. The stabilization cavities (626) can allow the cone (300) to be secured or compressed by the surgeon's fingers or other suitable devices. The stabilization cavities (626) can be positioned anywhere in the cone (300), for example, without limitation, in the choker (360), in the body (310) or the like. The stabilization cavities (626) can penetrate through the entire thickness of the choker (360), or, as shown in FIG. 9, the stabilization cavities (626) can be a cavity or a depression that partially penetrates the thickness of the choker (360). For example, without limitation, the stabilization cavities (626) can be cavities on the outer surface of the choker (360). In one embodiment, the stabilization cavities (626) can be aligned with the outer opening of a needle guide hole (621). For example, without limitation, where the needle guide hole (621) is positioned in a radial degree around the outside of the cone (300) of 0 °, the stabilization cavity (626) is positioned around the outside of the cone ( 300) at a radial degree of 0 °.
[0087] [0087] In one embodiment, the cone (300) has at least one circumferential indicator (629) to indicate the circumference of the lumen in the tissue. The circumferential indicator (629) can be a mark, symbol or line showing a distinguishable color, a protruding part or a recessed part when compared to the surface of the cone (300). In one embodiment, the circumferential indicator (629) is positioned on the surface of the body (310), the choker (360) or the like. The circumferential indicator (629) can extend circumferentially around the outer surface of the cone (300). The circumference of the circumferential indicator (629) can be of any length, for example, without limitation, the circumference of the circumferential indicator (629) can be 2 mm - 40 mm. The circumferential indicator (629) can be positioned in a plane perpendicular to the longitudinal axis of the cone (300). The circumferential indicator (629) can be positioned at a location in the cone (300) that corresponds to the desired circumference of the lumen in the tissue. For example, without limitation, where the desired circumference of the lumen in the fabric is 25 mm, the circumferential indicator (629) is positioned on the cone (300) where the circumference of the cone's cross section (300) is 25 mm. As another example, without limitation, where the desired lumen circumference in the fabric is 25 mm, the circumferential indicator (629) is positioned in the cone (300) where the distance between the circumferential indicator (629) and the distal end of the cone (300) is 30 mm.
[0088] [0088] The number of holes for the needle guide (621) will depend on the size of the cone (300). In the preferred embodiment, the cone (300) contains four needle guide holes
[0089] [0089] As shown in FIGS. 9 - 10, the angle β of the needle guide hole (621) can affect the distance D from the outer surface of the cone (300) that the suture penetrates into the fascia. For example, without limitation, a larger β angle will make the distance D of the suture in the fascia greater and a smaller β angle will make the distance D of the suture in the fascia less. Although all suitable angles of the needle guide holes (621) are contemplated, the angle β is preferably between 0 degrees and 90 degrees from the axial line (625).
[0090] [0090] In one embodiment, the needle guide hole (621) can be extended longitudinally or parallel to the longitudinal axis of the cone. In one embodiment, the needle guide hole (621) may have a right or left orientation. A needle guide hole (621) oriented to the right allows the user to insert the suture passage device (650) through the needle guide hole (621) using the right hand. Where the needle guide hole (621) is oriented to the right, the radial degrees around the outside of the cone (300) between the first opening (622) and the second opening (623) of the needle guide hole ( 621) are positive or rotate clockwise around the outside of the cone (300), for example, without limitation, the radial degrees can be 30o, 60o, 90o or the like.
[0091] [0091] In one embodiment, the second opening (623) is positioned in relation to the circumferential indicator (629) in order to allow the suture passage device (650) to pass through the cross section of the plane, where the circumferential indicator ( 629) is positioned outside the circumference of the circumferential indicator (629). For example, without limitation, the second opening (623) can be positioned close to the circumferential indicator (629).
[0092] [0092] In one embodiment, the angle β of the needle guide hole (621) and the distance between the second opening (623) and the circumferential indicator (629) are coordinated so as to allow the suture-passing device ( 650) pass through the cross section of the plane, on which the circumferential indicator (629) is positioned, at a desired distance D from the outer surface of the cone (300). This ensures that the suture pulls the lumen in the tissue to close without tearing through the fascia. The angle β of the needle guide hole (621) can be in the ranges of 0 ° and 60 ° and the distance between the second opening (623) and the circumferential indicator (629) can be in the ranges of 5 mm and 75 mm.

In a preferred embodiment, the needle guide holes (621a) and (621c) are substantially parallel to each other and the needle guide holes (621b) and (621d) are substantially parallel to each other. In a preferred embodiment, the needle guide holes (621) are positioned at substantially equal angles to the axial line (625). The needle guide hole (621) has a proximal hole (622) and a distal hole (623) where the needle guide hole (621) is positioned in such a way that the proximal hole (622) is located on the surface of the needle. proximal cavity (340) and the distal orifice (623) is located on the outer surface (303) of the cone (300). Although all suitable angles of the needle guide holes (621) are contemplated, the angle β is preferably between 0 degrees and 60 degrees from the axial line (625).
[0096] [0096] In one embodiment, the end (641) of the suture passes through the proximal hole (622a) of the needle guide hole (621a), passes through the needle guide hole (621a), exits the distal hole (623a ) from the needle guide hole (621a), passes through the desired body tissue (660) to be closed, and into the cavity in the body.
[0097] [0097] In the preferred embodiment, as shown in FIGS. 6c-6d, while retaining one end (642) of a closing suture (640) external to the closing device (600) and the cavity in the body, the other end (641) of the closing suture (640) is passed with a suture passage device (650) through the proximal hole (622a) of the needle guide hole (621a), through the needle guide hole (621a), through the distal hole (623a) of the needle guide hole ( 621a), through the body tissue (660) desired to be closed, and into the cavity in the body.
