Description

Single-handed endoscope object extraction device, object extraction forceps single-handed control device and object extraction forceps control accessory TECHNICAL FIELD

[0001] The present application relates to the field of medical devices, in particular to a single-handed endoscope object extraction device, an object extraction forceps single-handed control device and an object extraction forceps control accessory. BACKGROUND

[0002] Biopsy forceps are indispensable tools in endoscopy, usually combined with cystoscopes, ureteroscopes and other endoscopes for use, and can grab objects by closing the front end after operating the rear end, for operations such as tissue biopsy, foreign object removal, ureteral stent adjustment or removal.

[0003] Current biopsy forceps are usually assembled into the working channel of an endoscope for visual operation with the assistance of the endoscope. When the biopsy forceps are assembled into the endoscope, the operator needs to operate the endoscope and the biopsy forceps simultaneously to complete the required surgical operation.

[0004] However, since the current biopsy forceps have a scissors-like structure with two operating handles, and the operating end of the biopsy forceps cannot form a whole with the operating end of the endoscope, the operator needs to operate both the endoscope and the biopsy forceps with both hands or with the help of two people. Such double-handed operation or multi-person cooperation makes the operation more complicated, wastes manpower, and even prolongs the operation time. Moreover, it requires high technical skills and good cooperation, and cannot have deviations. Therefore, it is very important to solve the single-handed operation problem of the biopsy forceps after assembly with the endoscope. Single-handed operation can not only reduce the burden of the doctor, but also make the operation simple and enable the biopsy forceps to be better applied in clinical surgery.

[0005] The existing bladder flexible scope is mostly used in a special operating room when performing surgery, and a large number of doctors are needed in the special operating room. Biopsy forceps are needed when taking biopsy under the bladder flexible scope, and one person needs to hold and one person needs to control the biopsy forceps to enter, that is, one doctor needs to control the bladder flexible scope and one doctor needs to control the biopsy forceps when taking biopsy under the existing bladder flexible scope, which greatly wastes the manpower of the hospital and brings pressure on the already tight medical resources.

[0042] The following description is provided so that others skilled in the art can have the best chance of understanding the present application and its underlying principles. The preferred embodiments described in the following description are merely illustrative of the present application and should not be construed as limiting the present application. Other variations of the present application, which are not explicitly described or illustrated, will be readily appreciated by those skilled in the art, and the general principles defined herein can be applied to other embodiments and modifications without departing from the spirit and scope of the present application. It will be appreciated by those skilled in the art that the terms "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like as can be used herein, merely describe orientations in relation to the application as the application is shown in the drawings and as such should not be construed as limiting the application to a particular orientation, configuration, or use thereof. It will be understood by those within the art that, in general, terms used herein, and especially

[0043] Referring to FIGS. 3-9, a single-hand endoscope biopsy device according to the present application is shown. In the present application, the single-hand endoscope biopsy device is adapted to be detachably connected to an endoscope, and when assembled into the endoscope, the operator can operate the biopsy forceps and the endoscope simultaneously with one hand, wherein the endoscope can include, but is not limited to, cystoscopes, ureteroscopes, gastroscopes, enteroscopes, and other endoscopes. After the conventional biopsy forceps and endoscope are assembled, the operator needs to operate the endoscope with one hand and the biopsy forceps with the other hand, or two people need to work together to complete the simultaneous operation of the biopsy forceps and the endoscope, which is inconvenient, time-consuming, labor-intensive, and causes more trouble for the operator, and requires higher technical requirements for the operator, and even prolongs the operation time, wastes more medical resources, and is more disadvantageous for application in outpatient surgery where disinfection is inconvenient.

[0044] Referring to FIGS. 1A, 1B, and 2, a combination of a conventional biopsy forceps 8 and a cystoscope 9 is shown. The present application takes the cystoscope as an example to illustrate the current assembly method of the biopsy forceps and the endoscope, which is also applicable to other endoscopes. In the current assembly method, the biopsy forceps 8 are detachably assembled into the working channel of the cystoscope 9 and extend from the front end of the working channel, and the user needs to use both hands to operate the cystoscope with one hand and the biopsy forceps with the other hand, or two people need to work together to operate the cystoscope with one person and the biopsy forceps with the other person. Only in this mutual cooperation can the grabbing of tissues or other objects be completed.

[0045] Specifically, the conventional biopsy forceps 8 comprises a holding portion 81 and an entry end 82, the entry end 82 is adapted to be assembled into the working channel 90 of the cystoscope 9, the holding portion 81 of the biopsy forceps 8 is a double scissor structure with two holding handles 811 and 812, and has a finger fixing portion 813, wherein the finger fixing portion 813 is arranged at the front end of the holding handles 811 and 812, and a plurality of fingers are required to operate the two holding handles 811 and 812 and the finger fixing portion 813 simultaneously to use the biopsy forceps 8.

[0046] The operation mode of the biopsy forceps 8 makes the operator unable to operate the holding portion 81 of the biopsy forceps 8 with the same hand when operating the operating end of the cystoscope 9. Moreover, the holding portion 81 of the existing biopsy forceps 8 is not connected with the operating end 91 of the cystoscope 9, and the operator needs to hold the operating end 9 of the cystoscope to fix the cystoscope and hold the holding portion 81 of the biopsy forceps 8 to fix and operate the biopsy forceps 8, which requires high technical requirements for the operator, needs to be operated by two hands or multiple people, is time-consuming and laborious, and if the cooperation degree is not good, multiple operations are required, which prolongs the operation time and increases the pain of the patient. The single-handed endoscopic object taking device of the present application solves the problem of complex operation of the existing biopsy forceps after being connected with the endoscope, and makes the operation simple from the instrument aspect.

[0047] Referring to FIGS. 3 to 8, a single-handed endoscopic object taking device 10 according to a preferred embodiment of the present application is shown. In the present embodiment, the single-handed endoscopic object taking device 10 comprises a control handle 11, a main body 12 and a extraction head 13, the control handle 11 is connected to the rear end of the main body 12, the extraction head 13 is connected to the control handle 11 and is installed inside the main body 12, and the front end of the extraction head 13 can be extended from the front end of the main body 12 or retracted into the main body 12 under the control of the control handle 11.

[0048] Preferably, the endoscope is a cystoscope, the cystoscope has a working channel, in use, the single-handed endoscopic object taking device is installed in the working channel, and the control handle of the single-handed endoscopic object taking device is installed in the operating handle of the endoscope. The control handle is fixed around the operating handle of the endoscope in the form of a snap ring to reduce the space occupation of the handle of the endoscope.

[0049] The single-handed endoscopic object taking device 10 further comprises a connecting portion 14, the connecting portion 14 is arranged at the rear end of the main body 12 and is connected with the control handle 11, so that the single-handed endoscopic object taking device 10 is detachably connected with an endoscope through the connecting portion 14. When assembled into an endoscope, the operator can operate the control handle 11 and the operating end of the endoscope simultaneously with one hand.

[0050] The control handle 11 comprises a force applying unit 111 and a connecting end 112, the force applying unit 111 is connected to the connecting end 112, and the connecting part 14 is connected to the connecting end 112, so as to connect the single-hand endoscopic object taking device 10 to an endoscope.

[0051] The force applying unit 111 comprises a first force applying element 1111, a second force applying element 1112 and an elastic element 1113, the elastic element 1113 is connected between the first force applying element 1111 and the second force applying element 1112, and the distance between the first force applying element 1111 and the second force applying element 1112 changes with the deformation of the elastic element 1113.

[0052] When the elastic element 1113 is in a natural state, the first force applying element 1111 and the second force applying element 1112 keep the maximum distance; when external force is applied to the first force applying element 1111 and the second force applying element 1112 at the same time, the elastic element 1113 is compressed, and the distance between the first force applying element 1111 and the second force applying element 1112 is reduced; when the first force applying element 1111 or the second force applying element 1112 is released, the elastic element 1113 automatically rebounds to the natural state, at this time, the first force applying element 1111 and the second force applying element 1112 return to the maximum distance state. In the process of being compressed and automatically rebounding, the elastic element 1113 can control the movement of the extraction head 13, so that the extraction head 13 extends out of the main body 12 to grab the object to be grabbed, and automatically retracts into the main body 12 after use, which is simple to operate and saves time and effort.

[0053] As can be understood by those skilled in the art, the compressed elastic element 1113 can also return to the natural state by operating the first force applying element 1111 or the second force applying element 1112 in the opposite direction. The elastic element 1113 is implemented as a spring in this embodiment, and can also be implemented as an element made of other elastic materials and having the functions of being compressed and rebounding.

[0054] In this embodiment, the external force can be applied by placing the fingers at the second force applying element 1112 and placing the palm or fingers at the first force applying element 1111 and pressing the first force applying element 1111, which occupies fewer fingers and can also be used for other operations, and is suitable for integrated operation of the endoscope and biopsy forceps in combination with the endoscope. When holding the endoscope, the operator's hand can operate the control handle 13 at the same time.

[0055] The main body 12 comprises a clamp main body 121, a protection end 122 and a mounting channel 1201 and a protection cavity 1202, the clamp main body 121 is connected between the protection end 122 and the connecting end 112, wherein the protection end 122 is located at the front end of the clamp main body 121, and the connecting end 112 is located at the rear end of the clamp main body 121.

[0056] The mounting channel 1201 is arranged in the interior of the clamp main body 121, and the protection cavity 1202 is arranged in the interior of the protection end 122, wherein the protection cavity 1202 and the mounting channel 1201 are in communication and communicate through the front end and the rear end of the main body 12. The connecting end 112 has a connecting channel 1120, and the connecting channel 1120 is in communication with the mounting channel 1201. That is, the protection cavity 1202 and the connecting channel 1120 are in communication with the mounting channel 1201 at the front end and the rear end of the mounting channel 1201 respectively, so that the protection end 122, the clamp main body 121 and the connecting end 112 are in communication with each other, so as to facilitate the mounting of the extraction head 13.

[0057] The second force applying element 1112 is connected to the circumferential side of the rear part of the connecting end 112, and does not affect the opening of the mounting channel 1201. The connecting end 112 is adapted to be integrally formed with the second force applying element 1112, and is used for fixing the connecting part 14, so that the connecting end 112 is made of a relatively hard material, such as stainless steel.

[0058] The clamp main body 121 is adapted to be bent within a certain range, and can be bent along with the bending of the endoscope, so as to stretch into the lesion to grab the object such as tissue, and can be matched with various endoscopes to meet more clinical needs.

[0059] The extraction head 13 comprises a grabbing shaft 131 and a grabbing end 132, the grabbing end 132 is connected to the front end of the grabbing shaft 131, the rear end of the grabbing shaft 131 is connected to the first force applying element 1111, and the elastic element 1113 is sleeved on the part of the grabbing shaft 131 between the first force applying element 1111 and the second force applying element 1112.

[0060] Specifically, the rear end of the grabbing shaft 131 is connected to the first force applying element 1111, the elastic element 1113 is movably sleeved on the outside of the grabbing shaft 131, and the grabbing shaft 131 sequentially passes through the elastic element 1113, the connecting end 112, the clamp main body 121 and the protection end 122.

[0061] That is, the gripping shaft 131 is installed in the main body 12 through the connecting channel 1120 and the mounting channel 1201 and is adapted to move along the longitudinal direction of the connecting channel 1120 and the mounting channel 1201, and the gripping end 132 in a natural state is located in the protection cavity 1202, and with the movement of the gripping shaft 131, the gripping end 132 can extend outside the protection cavity 1202 to perform a gripping operation, and after use, the gripping end 132 can be retracted into the protection cavity 1202. Therefore, the protection end 122 and the protection cavity 1202 can accommodate the gripping end 132 to prevent it from scratching the skin and play a protective role for the tissue.

[0062] It is worth mentioning that since the gripping end 132 is in a retracted state in the protection cavity 1202, the protection end 122 can form a protection force on the gripping end 132 to prevent it from expanding, so that the gripping end 132 will only expand when it extends to the front end of the protection end 122.

[0063] The protection end 122 and the protection cavity 1202 are sized to match the gripping end 132, and the protection end 122 is made of a relatively hard material to prevent the gripping end 132 from expanding and deforming in the protection cavity 1202. Since the protection end 122 is relatively short, it will not affect the bending of the main body 121 to adapt to the physiological bending parts of the human body.

[0064] Since the size of the gripping end 132 after retraction is slightly larger than the size of the gripping shaft 131, the cross-sectional size of the protection cavity 1202 is slightly larger than the cross-sectional size of the mounting channel 1201, so that the gripping end 132 will not enter the mounting channel 1201 and will be stably located in the protection cavity 1202. With a slight external force applied to the force applying unit 111, the gripping end 132 can be easily pushed out of the protection end 122, which is very labor-saving and easier to achieve one-handed operation.

[0065] When the elastic element 1113 is in a natural state, the gripping end 132 of the extraction head 13 is located in the protection cavity 1202 and does not extend out of the protection end 122 of the front end of the main body 12. When the elastic element 1113 is in a compressed state, the gripping end 132 of the extraction head 13 is away from the protection cavity 1202, and the gripping end 132 extends to the front end of the protection end 122 to perform a gripping operation.

[0066] When external forces are applied to the first force applying element 1111 and the second force applying element 1112 simultaneously, the first force applying element 1111 moves towards the second force applying element 1112, the grabbing shaft 131 moves forward with the first force applying element 1111, at this time, the elastic element 1113 is compressed, and the grabbing end 132 moves forward with the movement of the grabbing shaft 131, leaving the protection cavity 1202 of the protection end 122, so that the grabbing end 132 extends out of the protection end 122 and is located at the front end of the protection end 122 to perform the corresponding grabbing operation.

[0067] It is worth mentioning that the grabbing end 132 comprises at least three grabbing elements 1321 and a grabbing cavity 1320, the grabbing elements 1321 are suitable for opening or closing and opening in different directions to form the grabbing cavity 1320, so as to grab the tissues, foreign matters and other objects of the lesion site.

[0068] When the grabbing end 132 is located in the protection cavity 1202, the grabbing elements 1321 are in a completely closed state. When the grabbing end 132 leaves the protection cavity 1202 and extends to the front end of the protection end 122, the grabbing elements 1321 are in an open state to grab the objects. After contacting the grabbed objects, the grabbed objects are located in the grabbing cavity 1320, at this time, the grabbing elements 1321 clamp the grabbed objects to form a clamping force to prevent the grabbed objects from falling. The grabbing elements 1321 carrying the grabbed objects cannot be completely retracted into the protection cavity 1202, thereby carrying the grabbed objects to grab the grabbed objects out of the working channel of the endoscope.

[0069] The size of the protection cavity 1202 is smaller than the size of the grabbing elements 1321 after opening, so that at this time, even if the first force applying element 1111 and the second force applying element 1112 are released, the grabbing end 132 carrying the grabbed objects will not be retracted into the protection cavity 1202, and the elastic element 1113 will not return to the natural state. When the grabbed objects are released, the grabbing end 132 will automatically close, thereby being retracted into the protection cavity 1202, and the elastic element 1113 will return to the natural state to perform the next grabbing operation.

[0070] In the embodiment, the grabbing elements 1321 are implemented as three, the three grabbing elements 1321 clamp the grabbed objects from three directions after opening, the force points are more, the clamping force is larger, the grabbed objects can be stably grabbed, and the grabbing cavity 1320 is formed to accommodate the grabbed objects without damaging the grabbed objects, so as to facilitate subsequent inspection.

[0071] It is understood by those skilled in the art that the three said gripping members 1321 are only taken as an example and are not limited to the above-mentioned number, and can also be implemented as other numbers of gripping members. For example, referring to FIG. 7, the said gripping members 1321 can also be implemented as four, five, etc., to form clamping from four or five directions to the gripping object, increase the clamping force, and firmly clamp.

[0072] It is worth mentioning that when the said gripping members 1321 are implemented as three or more than three, the cross-sectional size of the said gripping end 132 in the contracted state formed after the said gripping members 1321 are closed is larger than the cross-sectional size of the said gripping shaft 131, therefore, the said protection cavity 1202 is matched with the said gripping end 132 in the contracted state, and therefore, the size of the said protection cavity 1202 is larger than the size of the said installation channel 1201.

[0073] The said connecting part 14 comprises a connecting body 141, a fastener 142, an adjusting member 144, and a connecting cavity 143, the said connecting body 141 is connected between the said fastener 142 and the said connecting end 112, the said connecting cavity 143 is arranged in the middle of the said fastener 142, and the said adjusting member 144 is rotatably connected to the said connecting body fastener 142 and can open or close the said connecting cavity 143.

[0074] The said connecting cavity 143 is adapted to accommodate the operating end of the endoscope, and after being connected with the endoscope, the two are fixed through the connection between the said fastener 142 and the said adjusting member 144, so that the said connecting part 14 surrounds the operating end of the endoscope. When it is needed to separate the two, the said connecting part 14 can be separated from the operating end of the endoscope by opening the said fastener 142 through the said adjusting member 144.

[0075] One end of the said connecting body 141 is connected to the said connecting end 112 and is adapted to be integrally formed with the said connecting end 112.

[0143] In detail, the first resistance sleeve 612151 is detachably arranged on the collection seat 61213, and the first control cord 61231 passes through the first resistance sleeve 612151. The inner wall of the first resistance sleeve 612151 tightly extrudes the first control cord 61231, and the first resistance sleeve 612151 provides sufficient friction to the first control cord 61231 to maintain the tension of the first control cord 61231. That is, the first control cord 61231 is in a taut state at any time, and the operator can accurately control the movement of the slider 6122 when controlling the first pull ring 61241, so that the control of the operator becomes efficient, thereby improving the operation efficiency.

[0144] The second resistance sleeve 612152 is detachably arranged on the collection seat 61213, and the second control cord 61232 passes through the second resistance sleeve 612152. The inner wall of the second resistance sleeve 612152 tightly extrudes the second control cord 61232, and the second resistance sleeve 612152 provides sufficient friction to the second control cord 61232 to maintain the tension of the second control cord 61232. That is, the second control cord 61232 is in a taut state at any time, and the operator can accurately control the movement of the slider 6122 when controlling the second pull ring 61242, so that the control of the operator becomes efficient, thereby improving the operation efficiency.

[0145] The collection seat 61231 can concentrate the control cords 6123 at one position, so that the operator can control the slider 6122 to slide up and down at the same position, effectively avoiding the problem that the finger span is too large to be easily controlled due to the control of movement in two directions, thereby helping the operator to complete the biopsy sampling work by controlling the biopsy forceps 620 through the taking forceps one-hand control device 610 while holding the bladder flexible scope 630 with one hand.
