Problems solved by technology

[0004] However, when the motor fails to rotate or the battery or other power supply for the motor fails to provide enough power to the surgical instrument, the instrument must be removed immediately and replaced with a new one.
At this time, the end effector of the surgical cutting stapler may be in a locked state, the cutting member is

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. The handle assembly is provided with a power supply assembly and an emergency knife withdrawal device, and the power supply assembly provides a power source for the surgical instrument. The emergency tool retraction device is rotatable in a first direction, thereby driving the transmission mechanism to move from a distal end to a proximal end to retract the cutting member within the end effector to an initial position. According to the surgical instrument of the invention, when the electric circuit fails, the single-hand operation can realize the functions 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 is simple in operation and effectively reduces the secondary injury to the 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...
