Abstract

The invention relates to a hemorrhoid stapler, which comprises a nail anvil and a shell, wherein a staple magazine, a nail pusher, a closing mechanism, and a firing mechanism are installed in the shell, and the closing mechanism is used to drive the nail anvil to face the shell Move to form a jaw with the staple cartridge, and the firing mechanism is used to drive the pusher piece to move toward the nail abutment seat to push out the staples in the staple cartridge, and the nail anvil has a conical outer surface , the staple cartridge has an inner cavity for accommodating tissue, the shell is provided with several pull wire holes communicating with the inner cavity corresponding to the staple cartridge, and the shell is also provided with an electric power to drive the closing mechanism and the firing mechanism to work structure. The stapler is equipped with an electric power structure that drives the closing mechanism and the firing mechanism, so as to solve the problem of excessive pulling caused by the vibration of the arm during the excitation process brought by the large closing force, and avoid affecting the butt closure of the anastomotic port and the staple-forming effect‑ The incomplete or excessive extrusion of the nails can ensure the effect of the operation.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a hemorrhoid stapler. Background technique [0002] Existing hemorrhoid staplers mostly rely on manual disposable instruments. In surgical operations, doctors often need to rotate the knob at the end to close the proximal and distal tissues, and close the firing rod with both hands under reasonable tissue compression to complete the anastomosis. The firing process requires a huge firing force to complete the cutting and closure of the anastomotic stoma. Huge closing force brings excessive pulling due to arm shaking during excitation, which affects the butt closure of the anastomotic stoma and the effect of staple formation-incomplete or over-extrusion of the staples, resulting in potential leakage and irregular stenosis of the anastomotic stoma , Affect the effect of the operation and is not conducive to the postoperative recovery of the patient. At the same time, ...
