[0026] Please see Figures 1-5 As shown, this utility model is an adjustable linear cutting stapler, including a handle 1, a baffle 101 fixedly connected to the left side of the handle 1, a through groove opened on the side wall of the baffle 101, a fixed support rod 102 fixedly connected to the left side of the handle 1, a rotating support rod 103 rotatably connected to the end of the fixed support rod 102 away from the handle 1, and a stapler 104 provided at the end of the rotating support rod 103 away from the fixed support rod 102.

[0027] A steering assembly 2 is provided at the connection between the rotating support rod 103 and the fixed support rod 102. The steering assembly 2 includes a steering wheel 201. A shaft 202 is fixedly connected to the side of the steering wheel 201 near the rotating support rod 103. The outer surface of the shaft 202 is fixedly connected to the end of the rotating support rod 103 near the fixed support rod 102. The shaft 202 is rotatably connected to the end of the fixed support rod 102 near the rotating support rod 103. A connecting rod 203 is rotatably connected to the side of the steering wheel 201 away from the fixed support rod 102 via a round shaft. The end of the connecting rod 203 away from the steering wheel 201 is connected via a round shaft. A gear 204 is rotatably connected. By setting a steering component 2, specifically, the gear 204 drives the steering wheel 201 to rotate through the connecting rod 203. As the steering wheel 201 rotates, the steering wheel 201 controls the rotation of the rotating support rod 103 through the shaft 202, thereby driving the end stapler 104 to turn. The steering function allows the doctor to adjust the angle of the cutting stapler according to actual needs during the operation, so as to more easily reach the surgical site. The doctor can achieve better operation on the surgical site without changing the patient's position or adjusting the overall position of the surgical instruments.

[0028] The inner wall of gear 204 is rotatably connected to the top of gun handle 1. Gear 204 is meshed with rack 301 on the front side. Push block 302 is fixedly connected to the bottom of rack 301.

[0029] An electric push rod 303 is fixedly connected to the front of the gun handle 1, and the output end of the electric push rod 303 is fixedly connected to the side wall of the push block 302.

[0030] The rack 301 has an L-shaped groove on the side near the gun handle 1. A support block 304 is slidably connected to the inner wall of the L-shaped groove. The side of the support block 304 away from the rack 301 is fixedly connected to the outer surface of the gun handle 1.

[0031] A slot 105 is provided on the side of the rotating support rod 103 near the stapler 104. An installation and removal assembly 4 is provided inside the slot 105. The installation and removal assembly 4 includes a plug 401 that is slidably connected to the inner wall of the slot 105. The side of the plug 401 away from the slot 105 is fixedly connected to the end of the stapler 104 near the rotating support rod 103.

[0032] Arc-shaped spring pieces 402 are fixedly connected to both the front and back of the insert block 401, and a limit ring 405 is fixedly connected to the outer surface of the rotating support rod 103.

[0033] A rotating ring 403 is rotatably connected to the outer surface of the limiting ring 405. The outer surface of the rotating ring 403 is provided with stripes. Two anti-dislodgement blocks 404 are fixedly connected to the side of the rotating ring 403 near the arc-shaped spring 402. By setting the installation and removal component 4, specifically, as the insert block 401 is inserted, the arc-shaped springs 402 on both sides are locked into the inner wall of the slot 105. Rotating the rotating ring 403 counterclockwise causes the anti-dislodgement blocks 404 to be inserted into the inside of the arc-shaped spring 402, fixing the insert block 401 inside the slot 105, thereby fixing the stapler 104 to the end of the rotating support rod 103. Different surgeries may require different specifications and types of staplers 104. The convenient replacement allows doctors to select the appropriate stapler 104 according to the surgical needs, improving the flexibility and adaptability of the surgery.

[0034] A specific application of this embodiment is as follows: The end of the device is inserted into the patient's body. According to the location of the patient's wound, the angle of the instrument is adjusted. The electric push rod 303 is activated, which drives the rack 301 to move back and forth on the surface of the gun handle 1 through the push block 302. As the rack 301 moves, it drives the gear 204 to rotate. With the synchronous rotation of the gear 204, the gear 204 drives the steering wheel 201 to rotate through the connecting rod 203. As the steering wheel 201 rotates, it controls the rotation of the rotating support rod 103 through the shaft 202, thereby driving the end of the stapler 104 to rotate. The steering function allows the doctor to adjust the angle of the cutting stapler according to actual needs during the operation, so as to more easily reach the surgical site. The doctor can achieve precise operation on the surgical site without changing the patient's position or adjusting the overall position of the surgical instruments. The outer surface of the connecting rod 203 and the fixed support rod 102 is covered with a protective cover. The material of the protective cover is medical rubber.

[0035] When it is necessary to replace the end of the stapler 104, rotate the rotating ring 403 clockwise. As the rotating ring 403 rotates, it synchronously drives the anti-dislodgement block 404 away from the inside of the arc-shaped spring 402. At this time, moving the stapler 104 causes the insertion block 401 to disengage from the slot 105 at the end of the rotating support rod 103. During the process of the insertion block 401 moving away from the slot 105, the arc-shaped springs 402 connected to both sides of the insertion block 401 will be compressed and deformed, thereby ensuring that the insertion block 401 can be smoothly disengaged from the inside of the slot 105, allowing the stapler 104 of another specification to be directly inserted. Insert the insert 401 into the slot 105. As the insert 401 is inserted, the arc-shaped springs 402 on both sides are engaged with the inner wall of the slot 105. Rotating the rotating ring 403 counterclockwise causes the anti-dislodgement block 404 to be inserted into the arc-shaped spring 402, fixing the insert 401 inside the slot 105. This fixes the stapler 104 to the end of the rotating support rod 103. Different surgeries may require different specifications and types of staplers 104. The convenient replacement allows doctors to select the appropriate stapler 104 according to the surgical needs, improving the flexibility and adaptability of the surgery.
