Abstract

A surgical instrument includes a handle assembly, a shaft assembly, an end effector, and a transmission mechanism at least partially positioned within that handle assembly. A power supply assembly anda manual reset device are arranged in that handle assembly, and the power supply assembly provides a power source for the surgical instrument. The manual resetting device can rotate in the first direction or the second direction, so that the transmission mechanism can be driven to move from the distal end to the proximal end, and the transmission function of the transmission mechanism can be restored; wherein the second direction is opposite to the first direction. According to the surgical instrument of the invention, when the electric circuit fails, the single-hand operation can realize thefunctions of manually returning the cutting member and restoring the transmission mechanism, so that the surgical cutting stapler can be used normally. The control device of the invention can be operated simply, is safe, stable and reliable, and effectively reduces secondary injury to human body.

Description

technical field [0001] The invention relates to a surgical instrument and belongs to the field of medical instruments. Background technique [0002] The stapler suitable for surgical operations is a surgical cutting stapler that can remove excess tissue while suturing the patient's wound. match. The surgical cutting stapler enters the human body through the cannula of the trocar precisely positioned at the surgical site, and then makes a longitudinal incision in the tissue and applies staples on the opposite side of the incision, thereby separating and stapling the tissue, similar to staples machine. The surgical cutting stapler includes an end effector, and the end effector includes a staple cartridge seat and an abutment seat, and the staple cartridge seat is used to receive the staple cartridge; the surgical cutting stapler also includes a cutting member, and the cutting member is opposite to the nail cartridge The seat is operably supported, and the cutting member inc...
