Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a carpal tunnel endoscope, a wrist joint surgical instrument, a wrist joint surgical instrument kit, and a carpal tunnel endoscope system. Background Technology

[0002] During the surgical treatment of carpal tunnel syndrome, it is necessary to cut the skin and subcutaneous tissue of the patient's palm near the wrist, cut the aponeurosis and sever the transverse carpal ligament to reduce the compression of the nerves and blood vessels in the wrist.

[0003] In related technologies, open surgery or minimally invasive surgery are used to treat carpal tunnel syndrome. Open surgery is more invasive and the wound healing time is longer, while minimally invasive surgery is performed under carpal tunnel endoscopy, which can reduce the surgical incision and help postoperative recovery. Therefore, carpal tunnel endoscopy plays an important role in the surgical treatment of carpal tunnel syndrome.

[0004] However, in related technologies, the carpal tunnel endoscope and surgical instruments are separate. During surgery, the carpal tunnel endoscope and surgical instruments enter the wrist joint cavity through different approaches. That is, the carpal tunnel endoscope enters the wrist joint cavity through one approach to provide a field of view, while the surgical instruments enter the wrist joint cavity through another approach and are operated in coordination with the carpal tunnel endoscope. This structural form of the carpal tunnel endoscope and surgical instruments requires more or larger incisions and precise control of the angle of the surgical instruments to avoid mutual obstruction or collision between the surgical instruments and the carpal tunnel endoscope, thus complicating the surgical procedure.

[0005] Therefore, how to provide a wrist endoscope that reduces surgical incisions and minimizes the interaction between surgical instruments and the wrist endoscope during surgery is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a wrist endoscope that can reduce / smaller surgical incisions and reduce the interaction between surgical instruments and the wrist endoscope during surgery.

[0007] Another objective of this invention is to provide a wrist joint surgical instrument that can be used in conjunction with the aforementioned carpal tunnel endoscope, thereby reducing the size of the surgical incision and minimizing the interaction between the wrist joint surgical instrument and the carpal tunnel endoscope during surgery.

[0008] Another objective of this invention is to provide a wrist joint surgical instrument kit that includes the aforementioned wrist joint surgical instruments, which can reduce / smaller surgical incisions and reduce the interaction between the wrist joint surgical instruments and the carpal tunnel endoscope during surgery.

[0009] Another objective of this invention is to provide a carpal tunnel system comprising the aforementioned carpal tunnel endoscope and the aforementioned wrist joint surgical instruments, which can reduce / minimize surgical incisions and reduce the mutual influence between surgical instruments and the carpal tunnel endoscope during surgery.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A carpal tunnel endoscope, comprising:

[0012] A mirror body containing an image sensor, the mirror body including an insertion part and a handheld part connected to each other;

[0013] The distal end of the insertion part is provided with a light window for emitting light and a field of view for receiving light; in a position that avoids the light window and the field of view, the distal end of the insertion part is also provided with an instrument connection part, which is used to detachably connect a wrist joint surgical instrument, so that after the wrist joint surgical instrument is connected to the instrument connection part, the wrist joint surgical instrument at least partially avoids the light emitted from the light window and the light received from the field of view.

[0014] Optionally, the instrument connection portion includes a first rotary connection interface disposed on the distal outer periphery of the insertion portion.

[0015] Optionally, the handheld part includes:

[0016] A light source assembly is connected to the light guide window;

[0017] A wireless transmission module, which is communicatively connected to the image sensor and used for communicative connection with an external image processing host;

[0018] A battery module, which is electrically connected to both the image sensor and the light source assembly.

[0019] Optionally, a seal is provided at the connection between the insertion part and the handheld part, or the insertion part and the handheld part are integrally formed.

[0020] Optionally, the viewing window is a cover plate with hydrophobic or anti-fog properties; and / or, the viewing window is provided with a heating element for evaporating water mist from the viewing window.

[0021] Optionally, the light source assembly includes LEDs for providing different colors or combinations of different colors.

[0022] A wrist joint surgical instrument, comprising:

[0023] A connecting sleeve has an inner hole, and a lens body connecting part is provided at the proximal end of the connecting sleeve. The lens body connecting part is used to detachably connect to the distal end of the insertion part of any of the above-mentioned wrist tube mirrors, so that the light emitted and received by the wrist tube mirrors at least partially pass through the inner hole.

[0024] A treatment section for treating tissue during wrist joint surgery, the treatment section being connected to the distal end of the connecting sleeve, and the treatment section being at least partially bent toward the axis of the inner hole so that when the endoscope connection section is connected to the insertion section of the wrist endoscope, the light received by the wrist endoscope comes partly from the treatment section.

[0025] Optionally, the lens body connecting portion includes a second rotary connecting interface disposed on the proximal inner circumference of the connecting sleeve.

[0026] A wrist joint surgical instrument kit includes a plurality of the aforementioned wrist joint surgical instruments, wherein the endoscope connection portion of each of the wrist joint surgical instruments is adapted to the distal end of the insertion portion of the same carpal tunnel endoscope, and wherein the treatment portion of at least two of the wrist joint surgical instruments has a different shape.

[0027] A carpal tunnel endoscope system includes the carpal tunnel endoscope and the wrist joint surgical instrument kit, wherein any of the wrist joint surgical instruments in the wrist joint surgical instrument kit is detachably connected to the instrument connection portion of the insertion portion of the carpal tunnel endoscope.

[0028] The wrist tube endoscope provided by this utility model has the following beneficial effects:

[0029] This carpal tunnel endoscope is equipped with an instrument connection section for connecting wrist joint surgical instruments. During use, the surgical instruments are connected to the instrument connection section, forming an integrated structure. This allows the surgical instruments and the insertion section to be inserted into the wrist joint cavity through the same incision during surgery. Because the surgical instruments can at least partially avoid light emitted from the light window and received from the field of view, illumination can be provided using the light emitted from the light window, and images of the wrist joint cavity can be obtained using the light received from the field of view. This allows for operation of the surgical instruments under the view of the carpal tunnel endoscope. Therefore, this carpal tunnel endoscope helps reduce the number and size of surgical incisions, minimizing trauma to the patient. Furthermore, since the wrist joint surgical instruments are integrated into the insertion part of the carpal tunnel endoscope during use, the physical connection between the wrist joint surgical instruments and the instrument connection part determines the definite relative positional relationship between the wrist joint surgical instruments and the insertion part. During the operation of the wrist joint surgical instruments, the wrist joint surgical instruments and the insertion part of the carpal tunnel endoscope will not obstruct or collide with each other. Therefore, the mutual influence between the wrist joint surgical instruments and the carpal tunnel endoscope during surgery is avoided, which helps to reduce the control precision of the wrist joint surgical instruments and reduce the difficulty of the operation of the wrist joint surgical instruments.

[0030] In addition, the instrument connection part is used for detachable connection with wrist joint surgical instruments. Therefore, different wrist joint surgical instruments can be replaced by disassembly, which is beneficial for performing different surgical operations during the operation and improves the versatility and applicability of the carpal tunnel endoscope.

[0031] The wrist joint surgical instrument provided by this utility model has a mirror connection part for connecting with the instrument connection part of the carpal tunnel endoscope, and includes at least the above-mentioned beneficial effects.

[0032] The wrist joint surgical instrument kit provided by this utility model includes multiple wrist joint surgical instruments as described above, and at least includes the aforementioned beneficial effects.

[0033] The carpal tunnel endoscope system provided by this utility model includes the aforementioned carpal tunnel endoscope and the aforementioned wrist joint surgical instrument kit, and includes at least the aforementioned beneficial effects. Attached Figure Description

Detailed Implementation

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0045] The core of this invention is to provide a carpal tunnel endoscope that reduces surgical incisions and minimizes the interaction between surgical instruments and the endoscope during surgery. Another core aspect of this invention is to provide a wrist joint surgical instrument kit that works in conjunction with the aforementioned carpal tunnel endoscope, further reducing surgical incisions and the interaction between the surgical instruments and the endoscope during surgery. Yet another core aspect of this invention is to provide a wrist joint surgical instrument kit that includes the aforementioned wrist joint surgical instruments, further reducing surgical incisions and the interaction between the surgical instruments and the endoscope during surgery. Finally, a core aspect of this invention is to provide a carpal tunnel endoscope system that includes the aforementioned carpal tunnel endoscope, further reducing surgical incisions and the interaction between the surgical instruments and the endoscope during surgery.

[0046] Please refer to Figure 1 and Figure 2 This utility model provides a carpal tunnel endoscope, including a mirror body 1. The mirror body 1 includes an insertion part 11 and a handheld part 12 connected to each other. The distal end of the insertion part 11 is provided with a light window 112 for emitting light and a field of view 2 for receiving light. At a position that avoids the light window 112 and the field of view 2, the distal end of the insertion part 11 is also provided with an instrument connection part 111. The instrument connection part 111 is used to detachably connect a wrist joint surgical instrument so that after the wrist joint surgical instrument is connected to the instrument connection part 111, the wrist joint surgical instrument at least partially avoids the light emitted from the light window 112 and the light received from the field of view 2.

[0047] In other words, during use, the wrist joint surgical instrument is connected to the instrument connection part 111, so that the wrist joint surgical instrument and the insertion part 11 form an integral structure. In this way, during surgery, the wrist joint surgical instrument and the insertion part 11 can be inserted into the wrist joint cavity through the same incision. Since the wrist joint surgical instrument can avoid at least partially avoiding the light emitted from the light window 112 and the light received from the field of view 2, the image inside the wrist joint cavity can be obtained by using the light emitted from the light window 112 and the light received from the field of view 2. Thus, under the field of view of the carpal tunnel endoscope, the wrist joint surgical instrument can be operated. It can be seen that the carpal tunnel endoscope is beneficial to reduce the number of surgical incisions, reduce the surgical incision area, and reduce the trauma to the patient. Furthermore, since the wrist joint surgical instruments are integrated into the insertion part 11 of the carpal tunnel endoscope during use, the physical connection between the wrist joint surgical instruments and the instrument connection part 111 determines the definite relative positional relationship between the wrist joint surgical instruments and the insertion part 11. During the operation of the wrist joint surgical instruments, the wrist joint surgical instruments and the insertion part 11 of the carpal tunnel endoscope will not obstruct or collide with each other. Therefore, the mutual influence between the wrist joint surgical instruments and the carpal tunnel endoscope during surgery is avoided, which helps to reduce the control precision of the wrist joint surgical instruments and reduce the difficulty of operating the wrist joint surgical instruments.

[0048] In addition, the instrument connection part 111 is used for detachable connection with wrist joint surgical instruments. Therefore, different wrist joint surgical instruments can be replaced by disassembly, which is beneficial for performing different surgical operations during the operation and improves the versatility and applicability of the carpal tunnel endoscope.

[0049] Understandably, carpal tunnel syndrome surgery requires the use of various wrist joint surgical instruments, such as the probe 62, hook knife 63, and dissector. To facilitate the procedure, various instruments are needed. Figures 4-7 As shown, the wrist joint surgical instrument in this embodiment of the present invention includes at least a probe 62, a hook knife 63, a circular dissector 64, and a square dissector 65.

[0050] It should be noted that a device connection part 111 may be provided at the distal end of the insertion part 11, through which all wrist joint surgical instruments can be connected to the insertion part 11. That is, each wrist joint surgical instrument can be detachably connected to the device connection part 111. Alternatively, at least two device connection parts 111 may be provided at the distal end of the insertion part 11, through which all wrist joint surgical instruments can be connected to the insertion part 11. In this case, when multiple wrist joint surgical instruments are respectively connected to multiple device connection parts 111, the multiple wrist joint surgical instruments can enter the wrist joint cavity through different incisions.

[0051] Furthermore, the interfaces of the instrument connection part 111 for different wrist joint surgical instruments can be the same or different. That is, each wrist joint surgical instrument can be connected to the instrument connection part 111 through the same interface or through different interfaces. As long as it can achieve detachable connection between each wrist joint surgical instrument and the instrument connection part 111.

[0052] It should be noted that the specific structure of the instrument connection part 111 is not limited in this embodiment, as long as the instrument connection part 111 can be detachably connected to the wrist joint surgical instrument.

[0053] In some embodiments, the instrument connection portion 111 includes a first rotary connection interface disposed on the distal outer periphery of the insertion portion 11.

[0054] In other words, in this embodiment, the wrist joint surgical instrument is connected to the first rotary connection interface to realize the connection between the wrist joint surgical instrument and the distal end of the insertion part 11. During connection, the wrist joint surgical instrument can be rotated to achieve the engagement of the wrist joint surgical instrument and the first rotary connection interface. This connection structure is simple and easy to operate.

[0055] It is understood that, correspondingly, in some embodiments, the wrist joint surgical instrument is provided with a second rotary connection interface for engaging with the first rotary connection interface. During connection, the second rotary connection interface is engaged with the first rotary connection interface by rotating the wrist joint surgical instrument. During disassembly, the wrist joint surgical instrument is separated from the instrument connection part 111 by rotating it in the opposite direction. This connection method is simple and convenient to operate.

[0056] It should be noted that the first rotary connection interface can be an external thread (such as...). Figure 3 As shown), the second rotary connection interface can be an internal thread, that is, the wrist joint surgical instrument and the instrument connection part 111 can be connected by a threaded connection; or the first rotary connection interface and the second rotary connection interface can be a snap-fit ​​structure that cooperates with each other, and the first rotary connection interface and the second rotary connection interface can be engaged by a rotation operation.

[0057] In addition, it should be noted that the first rotary connection interface can serve as a universal interface for connecting multiple wrist joint surgical instruments. That is, at least two wrist joint surgical instruments can be detachably connected to the instrument connection part 111 through the first rotary connection interface. This structure is simple, which helps to simplify the structure of the instrument connection part 111 and facilitates the connection between each wrist joint surgical instrument and the instrument connection part 111, making operation convenient.

[0058] In addition, in related technologies, the carpal tunnel endoscope achieves image transmission between the image sensor and the external image processing host through a wired connection. However, this wired connection method is limited by the constraints of long cables, which brings many inconveniences to the surgical operation and has high maintenance costs.

[0059] To address the technical problem of the inconvenience caused by long cables during surgical procedures, such as Figure 1 and Figure 2 As shown, in some embodiments, the handheld unit 12 includes a light source assembly 3, a wireless transmission module 4, and a battery module 5. The light source assembly 3 is connected to the light guide window 112; the wireless transmission module 4 is communicatively connected to the image sensor and is used for communicative connection with an external image processing host; the battery module 5 is electrically connected to both the image sensor and the light source assembly 3. Exemplarily, the external image processing host is connected to a display.

[0060] In other words, in this embodiment, the light source component 3 is located inside the handheld part 12, eliminating the need for an optical cable connection to an external light source and preventing the optical cable from interfering with surgical operations. Furthermore, the image sensor is located inside the handheld part 12; for example, it can be placed inside the field of view 2, close to the field of view 2, or it can be placed inside the handheld part 12 via a light guide connection. The image sensor 2 is connected to an external image processing host via a wireless transmission module 4 to transmit real-time images to the external image processing host. Additionally, since the external image processing host is connected to a display, the images acquired by the image sensor 2 can be displayed in real-time on the display. This wireless connection method eliminates the connection cable between the wrist endoscope and the external image processing host, avoiding the constraints of long cables on the wrist endoscope, facilitating operation, and reducing cable maintenance costs. The wireless transmission module 4 can be a Bluetooth module. In addition, this embodiment uses battery module 5 to power image sensor 2 and light source assembly 3 respectively. By using battery module 5 to provide power, the wrist tube mirror can be wirelessly powered without connecting to an external power interface through a power cable. This further avoids the constraints of long cables and facilitates use and maintenance management.

[0061] Therefore, in this embodiment, the wrist cannula does not require cables such as optical cables and power cords, enabling completely wireless use, so that surgical operations are not interfered with by cables, and it is easy to use.

[0062] It should be noted that, as Figure 2 As shown, the image sensor can be connected to the wireless transmission module 4 via the image processor 21. That is, the image sensor is connected to the image processor 21, and the image processor 21 is connected to the wireless transmission module 4. The image processor 21 can be used to process the signals collected by the image sensor and transmit the processed image information to an external image processing host via the wireless transmission module 4.

[0063] Considering the structural layout, the image sensor can be located inside the insertion part 11, and the image processor 21 can be located inside the handheld part 12. In addition, the light source assembly 3 can be located inside the insertion part 11 or inside the handheld part 12, as long as the insertion part 11 is provided with a light window 112, through which the light from the light source assembly 3 can be introduced into the wrist joint cavity.

[0064] Understandably, the handheld part 12 is located at the end of the insertion part 11 away from the instrument connection part 111. To facilitate the operator's grip, the handheld part 12 can be ergonomically designed. For example, the handheld part 12 can be a cylindrical structure or other streamlined structure to facilitate the operator's grip and operation. In addition, in order to minimize the size of the wrist tube mirror, the handheld part 12 can adopt a stepped shape, provided that the internal structure of the mirror body 1, such as the light source assembly 3 and the wireless transmission module 4, is reasonably arranged.

[0065] In addition, among the related technologies, the carpal tunnel endoscope is a reusable endoscope, which is expensive and has high equipment maintenance costs. Moreover, it requires repeated disinfection, which poses a risk of cross-infection.

[0066] In order to reduce costs and avoid the risks of repeated disinfection and cross-infection, in some embodiments, the insertion part 11 and the hand-held part 12 are disposable sterile products.

[0067] In other words, the carpal tunnel endoscope in this embodiment is a disposable endoscope. Compared with reusable endoscopes, disposable endoscopes can use inexpensive medical-grade plastics, such as polycarbonate and ABS, to replace the metal and optical glass components of reusable endoscopes, thereby reducing material costs. In addition, disposable endoscopes can use low-cost image sensors 2 or optical fibers to replace complex optical lens systems, reducing the cost of precision lenses. Moreover, from a manufacturing process perspective, plastic parts can be mass-produced through injection molding and are conducive to modular design, thus simplifying production. Furthermore, no sterilization is required after use, greatly reducing maintenance costs and avoiding the risk of cross-infection.

[0068] In addition, in order to improve the overall waterproof performance of the wrist tube mirror, in some embodiments, a seal is provided at the connection between the insertion part 11 and the handheld part 12, or the insertion part 11 and the handheld part 12 are integrally formed.

[0069] In other words, in this embodiment, when the insertion part 11 and the handheld part 12 are separate structures, a sealing element is provided at the connection between the insertion part 11 and the handheld part 12 to improve the sealing performance at the connection between the insertion part 11 and the handheld part 12, thereby achieving the overall waterproof performance of the carpal tunnel endoscope. Alternatively, the insertion part 11 and the handheld part 12 can be integrally molded to achieve the overall waterproof performance of the carpal tunnel endoscope, preventing water from entering the inside of the carpal tunnel endoscope during surgery and affecting its normal use, thereby ensuring the reliability of the carpal tunnel endoscope during use.

[0070] In addition, it is understandable that during surgery, after the tissue is cut, blood, water mist, etc. will be generated. In order to avoid the blood, water mist, etc. generated during the operation from affecting the field of view of the image sensor 2 and the illumination of the light source component 3, in some embodiments, the field of view window 2 is a cover plate with hydrophobic or anti-fog properties.

[0071] In other words, this embodiment reduces the adhesion of blood and other tissues by using a hydrophobic cover plate, or avoids blood, water mist, etc. generated during the operation from hanging on the field of view 2 by using an anti-fog cover plate. This avoids blood, water mist, etc. generated during the operation from affecting the field of view 2, ensuring that there is no interruption of the field of view during the operation and ensuring the reliability of obtaining images inside the wrist joint cavity.

[0072] Furthermore, in some embodiments, the viewing window 2 is provided with a heating element for evaporating water mist from the viewing window 2.

[0073] In other words, this embodiment uses a heating element to heat the water mist on the viewing window 2, thereby ensuring the clarity of the viewing window 2, preventing the water mist from affecting the field of view of the viewing window 2, and ensuring the reliability of acquiring images inside the wrist joint cavity.

[0074] It should be noted that this embodiment does not limit the specific structure of the heating element or its specific setting method, as long as the heating element can evaporate the water mist on the viewing window 2.

[0075] Furthermore, when the handheld part 12 is equipped with a battery module 5, the heating element and the battery module 5 are electrically connected so that the battery module 5 can supply power to the heating element.

[0076] In addition, the above embodiments do not limit the specific structure of the light source component 3, as long as the light source component 3 can provide the required illumination.

[0077] In some embodiments, the light source assembly 3 includes LEDs for providing different colors or combinations of different colors.

[0078] In other words, this embodiment provides different lighting modes by offering LEDs of different colors or combinations of colors, thereby helping to provide targeted lighting solutions to improve the visibility of the surgical field and enhance the display of key tissues within the surgical field. Furthermore, LED lights can reduce the cost of the wrist endoscope, thus facilitating the widespread adoption of disposable medical devices.

[0079] For example, LED lights can provide single white light illumination or multi-spectral mixed illumination. This embodiment does not limit the specific lighting mode of the LED light, and relevant technologies can be consulted. It will not be described in detail here.

[0080] In addition to the aforementioned carpal tunnel endoscope, this utility model embodiment also provides a wrist joint surgical instrument, which includes a connecting sleeve 61 and treatment parts 62, 63, 64, 65. The connecting sleeve 61 has an inner hole, and a scope body connecting part is provided at the proximal end of the connecting sleeve 61. The scope body connecting part is used to detachably connect to the distal end of the insertion part 11 of the carpal tunnel endoscope, so that the light emitted and received by the carpal tunnel endoscope passes through the inner hole at least partially. The treatment parts 62, 63, 64, 65 are used to treat tissues during wrist joint surgery. The treatment parts 62, 63, 64, 65 are connected to the distal end of the connecting sleeve 61, and the treatment parts 62, 63, 64, 65 are at least partially bent toward the axis of the inner hole, so that when the scope body connecting part is connected to the insertion part 11 of the carpal tunnel endoscope, the light received by the carpal tunnel endoscope comes partly from the treatment parts 62, 63, 64, 65.

[0081] In other words, the wrist joint surgical instrument provided in this embodiment is applicable to the carpal tunnel endoscope disclosed in the above embodiments. During use, the wrist joint surgical instrument and carpal tunnel endoscope are used together to complete the surgery through their combined action. This wrist joint surgical instrument is compatible with the aforementioned carpal tunnel endoscope, which can reduce the number of surgical incisions, reduce the surgical incision area, and reduce trauma to the patient. Furthermore, during use, the wrist joint surgical instrument is integrated into the insertion part 11 of the carpal tunnel endoscope. The physical connection between the wrist joint surgical instrument and the instrument connection part 111 ensures a definite relative positional relationship between the wrist joint surgical instrument and the insertion part 11. During operation, the wrist joint surgical instrument and the insertion part 11 of the carpal tunnel endoscope will not obstruct or collide with each other. Therefore, mutual interference between the wrist joint surgical instrument and the carpal tunnel endoscope during surgery is avoided, which helps to reduce the control precision required for operating the wrist joint surgical instrument and reduces the difficulty of operating it.

[0082] Understandably, the inner hole of the connecting sleeve 61 can serve as a clearance portion, preventing light emitted and received by the carpal tunnel endoscope, thereby ensuring reliable illumination of the wrist joint cavity and enabling the image sensor to acquire images within the wrist joint cavity. Furthermore, the treatment sections 62, 63, 64, and 65 are at least partially bent towards the axis of the inner hole of the connecting sleeve 61. This facilitates the observation of the operation of the treatment sections 62, 63, 64, and 65 when the wrist joint surgical instruments are installed into the insertion section 11 of the carpal tunnel endoscope, ensuring that some of the light received by the carpal tunnel endoscope originates from the treatment sections 62, 63, 64, and 65. Additionally, this embodiment provides a scope body connecting section at the proximal end of the connecting sleeve 61, connecting it to the instrument connecting section 111 at the distal end of the insertion section 11 of the carpal tunnel endoscope, thus achieving the connection between the wrist joint surgical instruments and the carpal tunnel endoscope and ensuring their compatibility for use.

[0083] It should be noted that this embodiment does not limit the specific connection method between the endoscope body connecting part and the instrument connecting part 111, as long as the connection between the two can be achieved.

[0084] In some embodiments, the lens body connection portion includes a second rotary connection interface disposed on the proximal inner circumference of the connection sleeve 61.

[0085] Understandably, the second rotary connection interface is used to engage with the first rotary connection interface on the distal outer periphery of the insertion part 11. The rotation operation facilitates the installation and removal of wrist joint surgical instruments and the wrist cannula, simplifying the operation.

[0086] It should be noted that the above embodiments do not limit the specific structure of the treatment units 62, 63, 64, and 65. The treatment units 62, 63, 64, and 65 are used to treat tissues during wrist joint surgery, such as for dissection or cutting operations during surgery. For example, the treatment units 62, 63, 64, and 65 can be probes 62, hook knives 63, circular peelers 64, or square peelers 65, etc.

[0087] In addition to the aforementioned carpal tunnel endoscope and wrist joint surgical instruments, this utility model embodiment also provides a wrist joint surgical instrument kit, which includes multiple wrist joint surgical instruments disclosed in the above embodiments, wherein the endoscope connection portion of each wrist joint surgical instrument is adapted to the distal end of the insertion portion 11 of the same carpal tunnel endoscope, and wherein at least two wrist joint surgical instruments have different shapes of treatment portions 62, 63, 64, 65.

[0088] In other words, the wrist joint surgical instrument kit in this embodiment includes multiple wrist joint surgical instruments. These multiple instruments can be a series of wrist joint surgical instruments required during wrist joint surgery, meeting the needs of wrist joint surgery for a variety of instruments. The multiple wrist joint surgical instruments can include multiple wrist joint surgical instruments with identical structures, or they can include wrist joint surgical instruments with different structures, to meet the needs of different stages of the wrist joint surgical procedure. For example, different wrist joint surgical instruments can be used at different stages of the wrist joint surgical procedure. Alternatively, the doctor can select appropriate wrist joint surgical instruments according to their own habits.

[0089] It is understood that the wrist joint surgical instrument kit of this embodiment includes the wrist joint surgical instrument disclosed in the above embodiments, and at least includes the beneficial effects of the above wrist joint surgical instrument, which will not be repeated here.

[0090] In addition to the carpal tunnel endoscope, wrist joint surgical instruments, and wrist joint surgical instrument kits described above, this utility model embodiment also provides a carpal tunnel endoscope system, which includes the carpal tunnel endoscope disclosed in the above embodiments and the wrist joint surgical instrument kits disclosed in the above embodiments.
