Abstract

The invention discloses a manual control device for an electric drive mechanism, comprising a base; a linkage mechanism having a first position and a second position; a drive assembly that is pivotable about a pivot on the base in a first direction and a second direction, the second direction being opposite the first direction. The drive assembly is capable of driving a movable portion of the linkage mechanism to move between a first position and a second position. The drive assembly is brought into contact with or separated from the transmission mechanism by the mutual cooperation of the drive assembly and the linkage mechanism, thereby controlling the movement of the transmission mechanism. According to the control device of the transmission mechanism of the invention, when the circuit fails, the single-hand operation handle assembly can realize the functions of manually returning the cutting member and restoring the transmission mechanism, so that the surgical cutting stapler can benormally used. 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, in particular to a control device for a transmission mechanism, 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 cart...
