[0034] A limiting groove (not shown) is provided on the support frame 13 , and the firing trigger link 512 is slidably connected to the limiting groove. The firing trigger link 512 is slidably connected along the limiting groove, so that the upper end of the firing trigger link 512 can be inserted into the slot 1442 .

[0035] In this embodiment, a first waist-shaped groove 5121 is formed at the bottom of the firing trigger link 512, and a fixed shaft 5111 is fixedly mounted at one end of the firing trigger 511. The fixed shaft 5111 is inserted into the first waist-shaped groove 5121 and can slide along the length direction of the first waist-shaped groove 5121. Therefore, when the medical staff pulls the firing trigger 511 counterclockwise, the firing trigger link 512 is driven to move along the limit groove.

[0036] One side of the firing trigger 511 extends outward to form a toggle portion 5112, which is located at the rear side of the firing button 151 and close to the firing button 151. The firing button 151 is electrically connected to the battery for supplying power to the motor 111. When the medical staff pulls the firing trigger 511 counterclockwise, the toggle portion 5112 triggers the firing button 151, so that the battery supplies power to the motor 111, thereby driving the motor output cam 112 to rotate, and then driving the lever 513 to rotate, and the firing link 515 hinged to the lever 513 moves forward, and the firing link sliding pin 516 rotatably connected to the firing link 515 slides forward in the guide groove of the support frame 13, and pushes the bent push rod fixedly connected to the firing link sliding pin 516 forward. The bent push rod of the patent and the nail magazine assembly fixedly connected to the bent push rod and the nail support assembly at the front end have the same structure as the publication number CN201922473648.1, which will not be repeated here. , so as to realize the internal parts of the lumen pushing the nail magazine to bind and separate the inner wall of the tissue.

[0037] The safety button 152 is electrically connected to the battery, and the motor cam link 114 is located between the safety button 152 and the lower end of the lever 513. In this way, when the lever 513 rotates to abut against the motor cam link 114 and continues to rotate, the motor cam link 114 can be pressed tightly against the safety button 152, so that the battery is disconnected from supplying power to the motor 111. At this time, the nail magazine moves into place.

[0038] The safety trigger 52 includes a safety trigger 521 and a safety trigger connecting rod 522. The safety trigger 521 is rotatably mounted on the support frame 13. A second waist-shaped groove 5221 is provided at the bottom of the safety trigger connecting rod 522. A connecting shaft 5211 is fixedly mounted at one end of the safety trigger 521. The connecting shaft 5211 is inserted into the second waist-shaped groove 5121 and can slide along the length direction of the second waist-shaped groove 5221.

[0039] The upper end of the safety trigger link 522 has a notch 5221, and a butting portion 5222 is formed on the safety trigger link 522 above the notch 5221. In the initial state, the upper end of the firing trigger link 512 is inserted into the front end of the slot 1442 because the butting portion 5222 is stuck in the opening 1443. When the medical staff pulls the safety trigger 521 counterclockwise, the safety trigger link 522 moves upward, so that the supporting portion 5222 is separated from the opening 1443, and the notch 5221 reaches the position of the indicator needle pick 144. The indicator needle pick 144 moves forward under the elastic force of the compression spring 44, so that the groove wall of the groove 1441 pushes the blocking column 1431 to move, thereby driving the indicator needle 143 to rotate counterclockwise and move to the front side of the display window 142. At this time, the medical staff will know that the safety device has been opened, and can pull the firing trigger 511.

[0040] The specific implementation of the present invention is:

[0041] The medical staff rotates the adjustable knob 4, removes the anvil 3, places the anvil 3 into the tubular tissue, tightens the purse-string joint, holds the handle of the stapler body 1 with one hand, adjusts the head of the instrument to its position on the anvil 3, then rotates the adjustable knob 4 to tighten the gap between the anvil 3 and the lumen 2, the medical staff turns on the safety trigger 521, the indicator needle 143 rotates forward, confirms that the safety trigger 521 is on, pulls the firing trigger 511, and the firing link 515 connected to the end of the lever 513 moves forward to separate the tubular tissue, presses and releases the firing trigger 511, the motor 111 stops running, and then rotates the adjustable knob 4, and then takes out the stapler.
