    Endoscope angulation device, control device for peripheral endoscope elements and an endoscope drive tower
    OBJECT OF THE INVENTION
    The purpose of the present application is to register an angulation device for an endoscope of the flexible type, a control device for peripheral elements of said endoscope and a drive tower incorporating notable innovations.
    More specifically, the invention proposes the development of an angulation device that eliminates the use of conventional movement wheels, as well as a new control device for peripheral elements of the endoscope and a drive tower.
    15 which allows the body to be released from endoscopy of valves and pipes.
    BACKGROUND OF THE INVENTION
    The flexible endoscope is a medical probe for the exploration of the cavities of the
    20 human body, which is introduced through the holes and sphincters of the human body. This device has been used since the end of the 50s, without its format having varied significantly.
    The only notable variation since its creation was in the early 1990s, when it
    25 replaced the optical fiber with a micro camera, to take the image to a monitor. Until then the size of the cameras forced them to be placed outside.
    There is hardly any variation in the format of the endoscope body, between older and current models, except that in the place where there was an eyepiece, there is now a
    30 keypad for the remote control of the image processor, and now the connector between the endoscope and its control elements needs an electronic connection to the camera.
    This endoscope format, with slight aesthetic modifications, is the one that all endoscope manufacturers are currently using, because they all share the same system to angle the curved section.
    As can be seen in Figure 1, the current system for angular the bending section comprises for example a pair of wheels 401, 402, which act as controls, to rotate pulleys, or sprockets, which move a chain, or cable, which stretches from the cables of the curved portion. These cables are inside a spring, which runs through the entire insertion tube, so that movement is only possible in the bending section. The ends of the cables are fixed to the distal end of the bending portion.
    The bending portion is a piece composed of numerous metal rings arranged as a tube, angled in four directions, to guide the endoscope through the inside of the human body.
    From the first models this angulation system has always been used. Which has a first drawback: the number of pieces needed to perform that function.
    In addition there is the disadvantage of the little ergonomics that the current configuration of the endoscopes represents. One wheel must be turned with the fingertips of the left hand, with which the endoscope is held, while the other wheel is turned with the right hand.
    In addition, if you have to perform an operation to clean the lens, drive gases to the patient's body, aspirate liquids, or take a picture of the image with an image processor, etc. (peripherals) you must press one of the the buttons on the top of the case where the wheels are also located. This means having to release the wheel, for which there is to put the brake, or lengthen the fingers to the other end of the housing.
    It is necessary to take into account factors such as that there are people who have smaller hands than others, so it is very difficult for their fingers to reach the housing easily. In addition all the endoscopes are made to be used by right-handed people, since that is the hand that leaves "free" (after having stopped the control) for the
    P201 530615
    insertion of accessories through the endoscope channel, so that left-handed users are significantly harmed.
    Another drawback of the state of the art is that the endoscope body is provided with valves, interconnections and other types of commutations that may be the source of fluid leaks and the growth of harmful bacteria, fungi or viruses.
    DESCRIPTION OF THE INVENTION
    The present invention has been developed in order to provide an endoscope angulation device and a control device for peripheral elements of the endoscope that solves the aforementioned drawbacks, also providing additional advantages that will be apparent from the description that It is accompanied below.
    An object of the present invention is an endoscope angulation device of the flexible type comprising a bending portion and bending cables wrapped by covers, comprising an angled body of elongated configuration with a central axis arranged longitudinally along said angulation body, in which the angulation body in turn comprises a first angulation portion linked to a second angulation portion, said first and second angulation portion being articulated such that a relative reciprocating motion is defined between them with respect to to the central axis, at least a first bending cable being fixed to the first angulation portion and at least a first cover fixed to the second angulation portion, such that the relative reciprocating movement between the first angulation portion and the second angulation portion, causes the relative displacement of the first bending cable Regarding the first cover.
    Thanks to these characteristics, an angulation device is achieved that allows it to be used regardless of the size of the user's hands, and whether it is right or left handed. Angulation can be achieved with any of the hands, which does not currently happen with the movement wheels. In addition it is not necessary for the user to stop the endoscope when he has to operate the peripherals. In short, ergonomics are greatly optimized; it is only necessary to "bend" the angulation body so that the distal end of the endoscope (curved portion) is curved.
    P201 530615
    Another advantage achieved by the present invention is that the endoscope angulation system is greatly simplified, whereby manufacturing, maintenance and disinfection thereof are greatly facilitated, as well as the reduction of technical failures due to the wear of the greatest amount of parts compared to the prior art models.
    To facilitate the handling of the invention, the angulation body may additionally comprise a housing that envelops the different angulation portions, said housing having a first handle-like end. The housing may further comprise a second end opposite the first, at least one pair of projections diverging from each other having one of which covers and bending cables extend at said second end.
    In order to comfortably support the housing, the present endoscope angulation device may additionally comprise a support element which in turn comprises at least one support surface configured at least partially coinciding with the housing and a protrusion capable of fit between the pair of divergent projections in a condition of use. This support element may be linked to a pedestal, which may optionally be height adjustable. This support element thus allows comfortable angulation of several movements with one hand.
    Advantageously, the present endoscope angulation device may additionally comprise at least a third angulation portion linked to the second angulation portion, said second and third angulation portions being articulated such that a relative reciprocating motion between them is defined with respect to to the central axis, at least a second bending cable being fixed to the second angulation portion and at least a second cover fixed to the third angulation portion, such that the relative reciprocating movement between the second angulation portion and the third angulation portion, causes the relative displacement of the second bending cable with respect to the second cover. In this way, by being able to add as many angulation portions as necessary, angles can be made with more precise changes of direction, since these additional angulation portions can be attached to bending cables that make additional changes.
    Thus another additional advantage of the present design lies in the simplicity of use that allows two movements to be executed simultaneously, more quickly and easily, than can be done with an endoscope with movement wheels.
    In accordance with one embodiment, the angulation portions may comprise hollow tubes, a pair of angulation portions being linked with internally disposed stems in the angulation portions, the ends of said stems being attached to the respective angulation portions in shape. rotating each other. Preferably, the hollow tubes can be square in cross-section.
    Alternatively, the angulation portions may be linked to each other with a spherical joint or ball joint that may be advantageously limited to a degree of freedom. With this limitation it is achieved that the relative displacement between two angulation portions involves only the modification in one direction of the endoscope, facilitating intuitive user handling.
    The covers can be advantageously springs, since they protect the bending cables and have some flexibility to adopt the changes in the angulation of the endoscope.
    It is another object of the present invention a control device for peripheral elements of an endoscope comprising a plurality of electromyography sensors arranged on a band of elastic material configured particularly as a bracelet or the like, in which the electromyography sensors are susceptible of establishing a data communication with processing means and linked in turn in data communication with at least one peripheral element.
    In the present invention, the expression "peripheral elements" should be understood as those auxiliary elements for carrying out endoscopy, such as, for example, light source, water source, blowing, aspiration, chamber, etc. which in the present invention are advantageously located in a drive tower linked to the endoscope body itself. The drive tower will be the body that supports these peripheral elements comprising a valve or switch that manages its activation.
    The band may preferably be made of elastic material, which allows it to adapt optimally to the anatomy of the user.
    Advantageously, the housing described above may comprise marks
    5 presets located at the first end as a handle, which can advantageously berecesses or reliefs. Thanks to these preset marks, it is easy for the user to place their fingersover the angulation body in a concrete way, as if pressing a virtual button,to cause a series of electrical impulses at specific points of the muscles thatare measured by electromyography sensors and interpreted by the means of
    10 processing as a predefined order to drive certain peripheral elements.
    Alternatively, the control device for peripheral elements of an endoscope comprises a plurality of buttons arranged around a crown, in which the
    15 crown buttons are capable of establishing data communication with processing means and linked in turn to data communication with at least one peripheral element.
    Thanks to these characteristics, a couple of control devices are achieved to
    20 peripheral elements preferably and advantageously in cooperation with the angulation device described above to perform an ergonomic endoscopy. The user can hold the angulation body with both hands or even only one, and without having to release it, he can manipulate the control device that drives the peripheral elements of the endoscope through switching means. The means of
    The processing will receive the data of the electrical muscle impulses and interpret the action to be carried out.
    Advantageously, the crown can be configured so as to be able to establish a link with the first end of the housing as a fitting
    30 tongue and groove. This further facilitates the handling of the angulation body, since the angulation body can be introduced through the inner hole of the crown.
    Then the crown can be used as a removable control, with physical buttons and used used in another endoscope different from the original.
    Another object of the present invention is an endoscope drive tower comprising processing means and at least one peripheral element, in which the peripheral element in turn comprises switching means linked to the processing means, further comprising at least one outlet associated with the peripheral element and said outlet being susceptible to be connected to a conduit of the endoscope linked to an insertion tube; in which the processing means are likely to be linked in data communication with a control device for peripheral elements.
    Thanks to these characteristics, the endoscope body of valves, pistons and switches, necessary for the sending and return of fluids, the transmission of images or the light source, is released. Multiple interconnections of pipes and metal parts that are a special risk are eliminated, since they are areas of difficult cleaning and disinfection.
    In the present invention the drive tower may adopt any external configuration, for example a hub, prism, cylinder, etc. In addition, the duct can advantageously link the outlet with the other projection of the endoscope angulation device as defined above.
    As for the switching means, they can comprise a peristaltic pump, an electrovalve or a switch, necessary to allow the passage or block of fluids, the transmission of light or images.
    Other features and advantages of the endoscope angulation device, the control device for peripheral elements of the endoscope and the drive tower, objects of the present invention, will be apparent from the description of preferred, but not exclusive, embodiments illustrated. by way of non-limiting examples in the accompanying drawings, in which:

    DESCRIPTION OF A PREFERRED EMBODIMENT
    In view of the aforementioned figures and, in accordance with the numbering adopted, examples of preferred embodiments of the invention can be observed therein, which comprises the parts and elements indicated and described in detail below.
    Some non-visible elements have been represented with dashed lines for reasons of clarity.
    In Figures 2 -8 an angulation device 2 for endoscope 1 of the flexible type can be seen, comprising a bending portion 5 and bending cables 204, 206 wrapped by covers 205, 207. No more detail will be entered into this portion. of curved 5 of the endoscope since it will be of a type already available in the market.
    Continuing with the description, the angulation device 2 comprises an angulation body 20 of elongated configuration with a central axis E arranged longitudinally along said angulation body 20. The angulation body 20 in turn comprises a first angulation portion 201 linked to a second angulation portion 202, said first and second angulation portion 201, 202 being articulated such that a relative reciprocating motion is defined between them relative to the central axis E.
    Said reciprocating movement can be seen more clearly in Figures 2 and 3; in them it is observed how the first and second angulation portions 201, 202 are linked together so that a relative reciprocating movement between them is allowed. The position of part of the angulation body 20 varies with respect to the longitudinal axis E. The planned joints will be described later.
    A first bending cable 204 is fixed to the first angulation portion 201 and a first cover 205 is fixed to the second angulation portion 202, such that the relative reciprocating motion between the first angulation portion 201 and the second angulation portion 202, causes the relative displacement of the first bending cable 204 with respect to the first cover 205, so as to accurately angle the bending portion 5.
    Although this description refers to a single bending cable in the singular, it should be understood that it is preferred that said bending cables go in pairs as can be seen in figures 2, 3 and 4, and more preferably, arranged diametrically opposed with respect to the longitudinal axis E.
    Continuing with Figures 2 and 3, it can be seen that the angulation body 20 preferably comprises a housing 200 that envelops the different angulation portions 201, 202, said housing 200 presenting a first end 221 as a handle. The housing 200 further comprises a second end 223 opposite to the first, and at that second end 223 there are preferably provided a pair of projections 210 diverging from each other, and from at least one which extend the covers 205, 207 and the cables of bending 204, 206. It is clear that the number of projections 210 may be varied depending on the bending cables that are included in the invention or other connections that are to be provided. It can also be seen that between the first and second ends 221, 223, a central portion 222 has been arranged to remit the relative reciprocating movements, described above.
    P201 530615
    The housing 200 may be made of a plastic material suitable for use in medicine. Preferably the first and second ends 221, 223 and the central portion 222 will be tightly connected to each other for hygienic reasons.
    The present angulation device 2 further comprises a support element 212 which in turn comprises a support surface 213 configured at least partially coincident with the housing 200, that is to say that the support surface 213 has a complementary configuration with a part of the housing 200 to achieve a proper connection to each other. The support member 212 also comprises a protrusion 214 capable of fitting between the pair of divergent projections 210 in a condition of use, as shown in Figures 2 and 3. In this way the user can handle the angulation device 2 with a single hand, the other being free.
    Depending on the particular needs, the support element 212 may be linked to a pedestal 215 and even to a rotating anchoring point 216 that allow the height and inclination to be adjusted to the physical characteristics of the endoscope user 1, making ergonomics even easier. In the driving.
    It can be seen in FIGS. 2 and 3 that the angulation device 2 additionally comprises at least a third angulation portion 203 linked to the second angulation portion 202, said second and third angulation portions 202, 203 being articulated such that it is defined a relative reciprocating motion between them relative to the central axis E. This articulation is identical to that described for the first and second angulation portions 201, 202 And has the same technical effect, despite the relative reciprocating movement between the second and third angulation portion 202, 203 is produced in a direction other than the relative reciprocating motion between the first and second angulation portions 201, 202. The second bending cable 206 is fixed to the second angulation portion 202 and the second cover 207 is fixed to the third angle portion 203, such that the relative reciprocating motion between the second portion of angulation 202 and the third angulation portion 203, causes the relative displacement of the second bending cable 206 with respect to the second cover 207.
    As already mentioned, the relative reciprocating movement occurs in a different direction with respect to the longitudinal axis E for each joint, in this way it is possible to modify the angulation of the curved portion 5 in more directions. That is, to
    P201 530615
    as the number of angulation portions 201, 202, 203 increases the possibilities of varying the angle of the bending portion 5 of the endoscope 1.
    The fixing of the bending cables 204, 206 and the covers 205, 207 to the respective angulation portions 201, 202, 203 may be carried out in any known manner, such as welding, fasteners, rivets, etc. Preferably, both the bending cables 204, 206 and the covers 205, 207 are metallic and specifically the covers 205, 207 are springs. However, it will be obvious for the person skilled in the art to modify the materials and adapt the configuration of these elements to suit the particular needs.
    According to a first preferred embodiment of the angulation device 2, shown in Figures 2 and 3, the angulation portions 201, 202, 203 comprise hollow tubes, a pair of angulation portions being connected to each other with stems 208 whose ends 208 they are arranged internally in the angulation portions 201, 202, 203, the ends of said stems 208 being attached to the angulation portions 201, 202, 203 rotatably with each other. Even more preferably, the hollow tubes have a square cross-section, to facilitate the positioning of the bending cables 204, 206.
    In the present embodiment, the stems 208 are provided to be arranged in pairs for greater robustness although it is clear that the number may vary. These pairs of stems 208 can be attached to the hollow tubes for example by means of pins 209 that allow the relative rotation of the angulation portions 201, 202, 203 with each other. As can be seen in Figures 2 and 3, the pins 209 are arranged two by two for each joint, so that the two pairs of pins 209 have a different and offset location relative to the longitudinal axis E. This allows the relative reciprocating movement between the second and third angulation portions 202, 203 occurs in a different direction than the relative reciprocating motion between the first and second angulation portions 201, 202.
    A second embodiment of the angulation device 2 in which the angulation portions 201, 202, 203 are linked to each other with a spherical joint or ball joint 211. can be seen in FIG. 4. To achieve a reciprocating movement between the portions of 201, 202, 203, predictable and controlled angulation, spherical joint or
    P201 530615
    ball joint 211 may be advantageously limited to a degree of freedom. Other alternative embodiments may include springs (not shown) positioned between the angulation portions 201, 202, 203, also limited to a degree of freedom.
    Although articulations between angulation portions 201, 202, 203 with a single degree of freedom are preferred in the present description because of the simplicity of handling achieved, it will be apparent to employ joints that allow more degrees of freedom between angulation portions 201, 202, 203 And thus achieve relative movements between them in more directions relative to the longitudinal axis E.
    In another object of the invention a control device 3 for peripheral elements 72 of an endoscope 1 is described. According to a first embodiment of the control device 3 represented in Figures 2, 3 and 5, the control device 3 comprises a plurality of electromyography sensors 32 arranged on a band 31 of elastic material configured particularly as a bracelet 30 or the like. This bracelet 30 is intended to be placed in any part of the arm or of the user who handles the endoscope 1; that is, it is capable of positioning itself, for example, in the upper extremities corresponding to the hands that are used. The material of the band 31 may be any suitable, preferably elastic, since this ensures the fastening of the bracelet 30 regardless of the anatomy of the user.
    The electromyography sensors 32 are capable of establishing data communication with processing means 71 arranged in a drive tower 7 and linked in data communication at least with a peripheral element 72 arranged in a drive tower 7.
    The electromyography sensors 32 may be within the scope of the person skilled in the art, and be properly arranged in predetermined locations to measure the electrical impulses of the user's muscles. The data communication between the electromyography sensors 32 and the processing means 71 can be carried out, for example, wirelessly since this avoids the presence of cables and connections that would hinder the activity of specialized personnel.
    The peripheral elements 72 may be any of those mentioned hereinbefore and, thanks to the present invention, they may be managed within the drive tower 7. As for the processing means 71, they may comprise a processor or the like.
    In Fig. 8 a drive tower 7 is schematically illustrated which comprises the processing means 71 and a plurality of peripheral elements 72. The peripheral element 72 in turn comprises switching means 73 linked to the processing means 71 The drive tower 7 further comprises an outlet 74 associated with the peripheral element 72; there may be several outputs 74 associated respectively with each peripheral element 72.
    These switching means 73 may in turn comprise a peristaltic pump, an electrovalve, a switch, etc.
    Preferably, the conduit 8 links the outlet 74 with the other projection 210 of the angulation device 2.
    Unlike the known systems, in the present invention, for example, the pistons or bypass valves (not shown) for fluids such as water or gas can be placed in the drive tower 7 itself, avoiding the presence of said valves and connections in the body of the endoscope 1 (angulation device 2, control device 3, duct 8, insertion tube 4 or bending portion 5) and thus reduce its complexity and the possibility of leaks in said endoscope 1. Another problem What is solved is that the formation of "biofilm" that feeds the bacteria is avoided.
    Through the outlet 74 connecting the conduit 8 to the drive tower 7, for example the fluid required by the user is sent to the insertion tube 4 of the endoscope 1. The drive tower 7 becomes the place where it manages the operation of the different peripheral components of the endoscope 1, except for the angulation that is the responsibility of the angulation device 2. To manage said operation, the peripheral devices 72 preferably comprise switching means 73 that control the passage of fluids towards the distal end of the endoscope 1 to be introduced in a patient. Water irrigation can be managed by a peristaltic pump located in the drive tower 7, which in turn can be connected to a sterilized water supply source.
    P201 530615
    Returning to this first embodiment of the control device 3, and referring to FIG. 5, in the angulation body 20, specifically the housing 200, preset marks 33 located at the first end 221 may be present as a handle. These preset marks 33 can be recesses or reliefs, and allow the user to help position their fingers in the correct position so that their muscles monitored by electromyography sensors 32 generate electrical impulses (not shown) determined and associated with specific orders stored by the processing means 71.
    In alternative constructions to this first embodiment of the control device 3 not shown, monitoring and monitoring systems of the user's eyes can be established. By means of the orientation of the eyes, an order to be executed by the drive tower 7 can be selected while the angulation device 2 is handled by hand or hands. These systems can comprise any element that detects the positioning of the user's eyes. In another alternative, the user can handle with one hand the angulation device 2 and with the other arm perform gestures that are for example captured by cameras that recognize specific gestures that are compared by the processing means 71 with preset patterns of gestures associated with Concrete orders stored in the drive tower 7.
    In another alternative not shown, the control device 3 may include a system for capturing and recognizing voice commands, which are sent to the processing means 71, which in turn sends the instruction to the corresponding switching means 73 so that the Peripheral element 72 chosen execute the action.
    In a second embodiment of the control device 3 for peripheral elements 72, shown in Figures 6 and 7, it comprises a plurality of buttons 301 arranged around a crown 300, either closed as an "O" or open as a "C" , and the buttons 301 of the crown are capable of establishing a link in data communication with the processing means 71. As already mentioned above, these processing means 71 are also linked with the switching means 73 of the peripheral elements 72 arranged in a drive tower 7.
    To facilitate the handling of the crown 300, it is preferably configured so that it is capable of establishing a physical link with the first end 221 of the housing 200
    P201 530615
    as a tongue and groove lace (see figure 6 and 7). To secure in the tongue and groove fitting of the angulation body 20 and the crown 300, any anchoring means such as clips, hooks or the like can be arranged.
    The crown shape 300 facilitates the joint use with the angulation device 2; The user has at his disposal the necessary buttons to execute the orders in an accessible and ergonomic way.
    In short, this crown 300 must be understood as a synonym for remote control, which can be protected by a case or bag for hygiene reasons, and which can be associated with various endoscopes 1.
    In a condition of use, the user will move the angulation portions 201, 202, 203 together to introduce the distal end of the endoscope 1 into the patient's body, following arrows 01 and 02. With the relative movement between two of said portions of angle 201, 202, 203, the relative displacement of a bending cable 204, 206 with respect to the covers 205, 207 is achieved. This relative displacement causes the bending portion 5 through which the curvature cables 204, 206 Y run covers 205, 207, adopt the necessary angulation. One end of the bending cable 204, 206 will be fixed to an angulation portion 201, 202, 203 and the other end with the distal end of the bending portion 5. The movement, for example, of the first angulation portion 201 with respect to the Second angle portion 202 as illustrated in Figures 2 or 3, will cause the stretching or pushing of the first bending cable 204 from or to its first cover 205, and this stretching or contraction will logically be transmitted throughout the first bending cable 204, causing the bending portion 5 to be in an upright or curved position.
    In the present invention when a pair of first bending cables 204 is available, when one of them is stretched, the other which is preferably located diametrically opposite to the longitudinal axis E, contracts, and thus is able to force the portion of curved 5 to adopt a certain curvature.
    If the user wishes to specify more a direction of bending of the bending portion 5, he can repeat the operation with the relative movement between the second and third angulation portions 202, 203. And all this with one hand thanks to the support element 212 .
    P201 530615
    Preferably but not exclusively, and having seen the angulation body 20 in plan, the arrangement of the pair of the first bending wires 204 and of the pair of the second bending wires 206, would represent the four cardinal points of a compass, since there would be a bending cable every 902 • Similarly, it can be said that these positions allow the bending portion 5 to bend to the right or left and up
    or down in a condition of use.
    The user can be guided with a screen as in the known endoscopes to access the objective of the endoscopy and if you need, for example, to clean the lens of the endoscope 1, you can position your fingers on the preset marks 33, the electromyography sensors 32 will read this position through the electrical impulses of the muscles, for example of the arm, and will send the information to the processing means 71 that will compare the reading sent by the electromyography sensors 32 with previously stored patterns and when they detect the coincidence of the reading with the Patterns will execute the associated order. A peristaltic pump will propel the fluid through the entire body of the endoscope 1 from the conduit 10 8, through a projection 210 and converging with the bending wires 205, 207. The fluid will reach the distal point of the endoscope 1 through an endoscope channel (not shown) that runs inside the insertion tube 4 and the bending portion 5.
    In the case of using the remote control or crown 300, the user will have said crown 300 positioned preferably as illustrated in Figures 6 and 7.
