Embodiment Construction

[0040] The principle and spirit of the present invention will be described below with reference to several exemplary embodiments. It should be understood that these embodiments are given only to enable those skilled in the art to better understand and implement the present invention, rather than to limit the scope of the present invention in any way. Rather, these embodiments are provided to make the disclosure of this application more thorough and complete, and to fully convey the scope of the disclosure of this application to those skilled in the art.

[0041] Summary of the invention

[0042] Technical problem 1: In the prior art, the rack of the transmission part cooperates with the retraction push button through the end face of the chute to realize the automatic retraction of the instrument. When the control stroke is inaccurate in this kind of cooperation method, the stroke of the instrument will be retracted too much. The problem of too much or too little may cause t...

Abstract

The invention provides an automatic return device for an electric anastomat, the electric anastomat comprises a support and an operating handle, the support is fixed in the operating handle, and the automatic return device comprises a motor, a gear, a gear rack, an automatic return switch, a return elastic component and a return push button. The return elastic component is fixed between the support and the return push button, the gear rack is in contact with the return push button, the motor is connected with the gear rack through the gear, the return push button is in contact with the returnelastic component, and the automatic return switch is fixed in the operating handle. The automatic return device can complete automatic return of the instrument at the end of a percussion stroke, andis safe and reliable without being influenced by factors such as incomplete return and the like by means of a control mode of the automatic return switch by resetting of the return spring.

Description

technical field [0001] The invention relates to the field of medical instruments, and further relates to an electric stapler, in particular to an automatic retracting device for the electric stapler and the electric stapler thereof. Background technique [0002] Laparoscopic Cutting Stapler is used for suturing, cutting and separating tissues and organs in laparoscopic and open surgery. At present, most of the existing technologies directly realize the triggering and retreating actions of the stapler manually, and the purpose of retreating the cutting knife is achieved by pulling the reset cap backward to drive the rack to retreat. [0003] In the process of pulling back the reset cap to drive the rack back, there is a situation where the pulling force is too large and the operator has a bad hand experience, and it is not easy to be used by operators with smaller physiques or less strength. [0004] Therefore, an automatic rollback method needs to be proposed to replace man...
