[0002] Carpal tunnel syndrome is one of the common diseases of middle-aged and elderly people. When conservative treatment is ineffective, it is usually treated by joint ligament incision and median nerve release and decompression. However, the current related medical devices cannot bring good surgical effects.

[0003] For example, in the Chinese patent document with the authorization announcement number CN 206792439 U, the arthroscopic intervention kit is of a split type. The kit includes a cannula, a hook knife, a dissector, etc. The hook knife and the dissector need to be inserted into the cannula to work. The arthroscopic access kit is provided with an arthroscope. During use, the arthroscope can be inserted into the oval groove along the axial direction of the arthroscope through hole to replace the support inner core, so that the doctor can clearly see the joint ligament fibrous tissue. However, in this solution, the cutting heads of each tool are fixed, and it is inevitable to cause damage to the internal tissues when replacing the tools during the operation. Moreover, in this solution, both the arthroscope and the tools are arranged in the arthroscopic intervention kit in a separable plug-in manner. When plugged into the kit, there will be uncertainty in the shooting angle of the arthroscope and the working range of the tool, resulting in a deviation in the shooting angle and making it inconvenient for the doctor to observe the internal environment of the body.

[0047] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0048] Embodiment 1

[0049] The present invention provides an arthroscopic intervention device, as Figure 1 and Figure 2 shown, including a handle 20, an intervention tube body 30, a push rod 50 and a camera module 802. One end of the intervention tube body 30 is fixed inside the handle 20, and the other end has a first accommodation cavity. The push rod 50 is inserted into the intervention tube body 30. One end of the push rod 50 is located inside the handle 20, and the other end is rotatably connected to a blade 80. When the push rod 50 moves inside the intervention tube body 30, the blade 80 can contract into the first accommodation cavity or be erected as the push rod 50 moves. For example, when the push rod 50 is pushed to the first position of the intervention tube body 30, the cutting edge of the blade 80 is received into the first accommodation cavity (contracted), and when the push rod 50 is retracted to the second position, the cutting edge of the blade 80 extends out of the first accommodation cavity (erected). As Figure 2 、 Figure 5 、 Figure 9 and Figure 10 shown, the inner wall of the first accommodation cavity has a rotating shaft hole 3011, and the blade body of the blade 80 has an arc hole. The bottom end of the blade 80 is hinged to the push rod 50 through a rotating part 5011 to achieve relative rotation. The blade 80 is rotatably connected to the intervention tube body 30 through the cooperation of a rotating shaft 801 and the arc hole. When the rotating shaft 801 is located at the top end of the arc hole (the end of the arc hole close to the cutting edge), the push rod 50 is pushed to the first position of the intervention tube body 30, thereby contracting the blade 80 into the first accommodation cavity; when the rotating shaft 801 is located at the bottom end of the arc hole (the end of the arc hole far from the cutting edge), the push rod 50 is retracted to the second position, thereby erecting the blade 80 so that the cutting edge extends out of the first accommodation cavity. At the same time, the arc hole can also be a rhombus hole, an elliptical hole, etc.; the blade 80 can also be contracted or erected by means of gear cooperation. The blade 80 can be conveniently contracted or erected, thereby avoiding damage to human tissues that do not need to be cut.

[0050] The imaging module 802 is located in the first accommodation cavity and integrates an imaging device and a light source. The imaging device can be a camera, a video camera, etc., and the light source can be an LED lamp, a light bulb, etc. The imaging module 802 is horizontally inclined and fixed on the interventional tube body 30, so that the shooting direction of the imaging device and the projection light direction of the light source are aligned with the position where the cutting edge of the blade 80 extends out of the first accommodation cavity. The light source provides necessary light for the imaging device, and the imaging device can take pictures or videos of the environment near the cutting edge of the blade 80 during the operation, so as to facilitate medical staff to observe the internal environment of the body and provide help for subsequent procedures. The imaging module 802 can also be set on the interventional tube body 30 at any angle such as vertically or horizontally, but in order to ensure the appropriate shooting angle, a light reflection device needs to be set.

[0051] As Figures 6 - 8 shown, the handle 20 includes a housing, and the housing is in an "8" shape, with both ends larger than the middle, which is convenient for medical staff to operate. The housing includes a first housing 201 and a second housing 202. There are a blocking block 701 and a guiding block 702 inside the housing. The side wall of the housing has a first opening 601, the blocking block 701 has a second opening 602, and the guiding block 702 has a third opening 603. The first opening 601, the second opening 602, and the third opening 603 are arranged in sequence. A second accommodation cavity 704 is formed in the area between the blocking block 701 and the side wall of the housing, and a third accommodation cavity 705 is formed in the area between the blocking block 701 and the guiding block 702. The interventional tube body 30 includes a sleeve 301 and a fixed end connected to the sleeve 301. The fixed end is erected on the first opening 601, the second opening 602, and the third opening 603. One end of the sleeve 301 away from the fixed end is provided with a first accommodation cavity, and the end face has a rounded corner transition, which can avoid damaging human tissues when the sleeve 301 enters the body. The imaging module 802 is horizontally inclined and fixed on the sleeve 301. The fixed end is provided with a first clamping portion 302 and a second clamping portion 303. One side of the second clamping portion 303 has a clamping protrusion 3031. The first clamping portion 302 is located in the second accommodation cavity 704, and the size of the first clamping portion 302 is larger than the opening sizes of the first opening 601 and the second opening 602. The clamping protrusion 3031 is located in the third accommodation cavity 705, so as to fix the interventional tube body 30 in the handle 20. There is a fixing rod 2011 inside the first housing 201, and a fixing hole 2021 is provided at a position corresponding to the fixing rod 2011 inside the second housing 202. The fixing rod 2011 and the fixing hole 2021 cooperate with each other to fixedly connect the first housing 201 and the second housing 202. Of course, the first housing 201 and the second housing 202 can also be integrally formed, and the interventional tube body 30 and the handle 20 can also be integrally formed.

[0052] As Figure 2 、 Figure 8 and Figure 11As shown, the driving device 40 is provided with a button 401, a sliding block 402, and a driving block 403 in sequence from top to bottom. The first housing 201 has a sliding hole 2012, and a sliding groove 2013 is provided around the sliding hole 2012. The sliding block 402 is slidably arranged in the sliding hole 2012, the button 401 is slidably arranged on the sliding groove 2013, and the driving block 403 is located inside the first housing 201. The pushing rod 50 includes a pushing rod body 501 and a force-receiving block 502 connected in sequence. The pushing rod body 501 is located at the end of the second clamping portion 303 opposite to the clamping protrusion 3031 and penetrates through the intervention tube body 30. The force-receiving block 502 is arranged in the third opening 603 and is located between the blocking block 701 and the driving block 403, and the driving block 403 abuts against the force-receiving block 502. Pushing the button 401 forward slides in the sliding groove 2013, thereby driving the sliding block 402 to slide in the sliding hole 2012. The driving block 403 is driven by the sliding block 402 to drive the force-receiving block 502 to move forward, and then the blade 80 is contracted in the first accommodating cavity.

[0053] As Figure 4 and Figure 10 shown, an elastic component connecting portion 5021 is provided on the force-receiving block 502. One end of the elastic component 503 is fixed on the elastic component connecting portion 5021, and the other end is fixed on the fixing rod 2011. When no forward thrust is applied to the button 401, the elastic component 503 can pull back the pushing rod 50 to restore the pushing rod 50 to its original position, and finally make the blade 80 vertical. The cooperation between the rotating shaft 801 and the arc-shaped hole, the cooperation between the force-receiving block 502 and the blocking block 701, the cooperation between the sliding block 402 and the sliding hole 2012, and the cooperation between the button 401 and the sliding groove 2013 will all limit the rotation angle of the blade 80 to make the blade 80 in the best cutting position. The elastic component 503 can be a spring, a leaf spring, etc.

[0054] Reinforcing ribs 703 are provided inside the housing. The side wall of the first housing 201 has a first wire opening 2031, and the side wall of the second housing 202 has a second wire opening 2032. The first wire opening 2031 and the second wire opening 2032 cooperate with each other to form a wire through hole 203. The wire through hole 203 is located at the end of the handle far from the intervention tube body 30. A scale tube can be provided on the side wall of the sleeve 301, for example, on the side wall in the opening direction of the first accommodating cavity, to facilitate medical staff to know the position of the blade 80 in the body.

[0055] Embodiment 2

[0056] The present invention also provides a joint intervention system, as Figures 1 - 12As shown in the figure, it includes a display 90 and the above-mentioned joint intervention device 10. The joint intervention device 10 is connected to the display 90, and the joint intervention device 10 can be connected to the display 90 in a wired or wireless manner.
