[0030] See also Figure 1 The stapler assembly 100 includes a stapler body 110, a handle 120, a movable handle 130 and a stapler 140. The handle 120 is fixedly connected to the stapler body 110, the movable handle 130 is arranged on one side of the stapler body 110, and the stapler 140 is arranged at one end of the stapler body 110. The working principle and wiring method of the stapler 140 are commonplace, and they are all conventional means or common knowledge, and will not be repeated here.

[0031] See also Figure 1-4The positioning assembly 200 includes a fixed frame 210, an elastic holder 220, an elastic rod 230 and a limiting seat 240. The fixed frame 210 is arranged on the surface of the handle 120, the elastic holder 220 is arranged on one side of the fixed frame 210, and the elastic rod 230 is correspondingly arranged inside the fixed frame 210. The elastic rod 230 is clamped with the elastic holder 220, and the limiting seat 240 is fixedly connected with the elastic rod 230. The limiting seat 240 contacts the movable handle 130. A cavity 211 is correspondingly arranged inside the fixed frame 210. The cavity 211 can play a role in limiting. A bolt 212 is arranged on one side of the fixed frame 210, and the bolt 212 is threadedly connected with the handle 120. The fixing frame 210 can be conveniently disassembled and installed by fixing it with the handle 120 through the bolt 212. The elastic socket 220 includes a fixing plate 221, a first spring 222, a shift block 223 and an insertion rod 224. The first spring 222 is arranged inside the fixing plate 221. The shift block 223 is fixedly connected to the first spring 222. The shift block 223 is slidably connected to the fixing plate 221. The insertion rod 224 is fixedly connected to the shift block 223. The insertion rod 224 is connected to one side of the fixing frame 210. The shift block 223 is moved upward by the thumb and pushed downward by the elastic force of the first spring 222 to play the role of positioning and canceling the clamping.

[0032] In some specific embodiments, the elastic rod 230 includes a slide bar 231 and a second spring 232. The slide bar 231 is slidably connected to the cavity 211, and the second spring 232 is fixedly connected to the slide bar 231.

A through hole 2311 is correspondingly provided on the surface of the slide bar 231. The slide bar 231 is slidably connected to the through hole 2311. When the movable handle 130 needs to be locked, the user can use the thumb to move the dial block 223 upward to lock the second spring 232. A spring 222 moves, and then drives the insertion rod 224 to move upward and separate from the through hole 2311. The elastic force of the second spring 232 pushes the sliding rod 231 to extend from the inside of the cavity 211, and then drives the limit seat 240 to be in close contact with the movable handle 130. Then, the elastic force of the first spring 222 pushes the insertion rod 224 to be inserted into the inside of the through hole 2311, so that the sliding rod 231 can be fixed, so that the limit seat 240 can be fixed. A groove 241 is set on one side of the limit seat 240, and the movable handle 130 is in contact with the groove 241. The setting of the groove 241 can play a limiting role.

[0033] The utility model further provides a laparoscope linear cutting stapler, comprising the above-mentioned anti-mistouch structure.

[0034] The anti-mistouch structure and the working principle of the laparoscopic linear cutting stapler are as follows: the user can quickly sew the position to be sutured through the stapler body 110 and the stapler 140. When the movable handle 130 needs to be locked, the user can use the thumb to move the dial block 223 upward to move the first spring 222, and then drive the insertion rod 224 to move upward and separate from the through hole 2311. The elastic force of the second spring 232 pushes the sliding rod 231 out of the cavity 211, and then drives the limit seat 240 to be tightly connected with the movable handle 130. The movable handle 130 is locked to prevent the movable handle 130 from being accidentally touched when suturing is not required, thereby causing secondary injury to the patient. Furthermore, by locking the movable handle 130, it is prevented from being accidentally touched and causing continuous firing, causing pain to the patient, and facilitating the positioning of the movable handle 130, thereby improving practicality.

[0035] It should be noted that the specific model and specifications of the stapler 140 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.
