Indicating device of stitching instrument with knife and stitching instrument with indicating device

Abstract

The invention provides an indicating device of a stitching instrument with a knife. The indicating device comprises a fixing frame, a mobile indicating frame, an indicating window, an elastic piece, a connecting rope and a sliding clamping block. The fixing frame is arranged on a clamping plate of the stitching instrument with the knife. The mobile indicating frame is arranged on the fixing frame and can move relative to the fixing frame. The indicating window is connected with the fixing frame. The elastic piece is arranged on the fixing frame, and one end of the elastic piece is connected with the mobile indicating frame. The connecting rope is connected with the mobile indicating frame. The sliding clamping block is arranged in a screw bin frame of the stitching instrument with the knife. The sliding clamping block is provided with an elastic protrusion, and one end of the sliding clamping block is connected with the connecting rope. According to the stitching instrument with the knife, a cutting knife can touch the sliding clamping block after cutting, so that the mobile indicating frame moves, and accordingly an operator observes color changing from the indicating window and judges whether the cutting process is completed, the fact that the cutting process is completely over is guaranteed, and medical accidents are avoided. The invention further provides the stitching instrument with the knife, and the stitching instrument with the knife comprises the indicating device.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an indicating device for a stapler with a knife. The present invention also relates to a stapler with a knife comprising the above-mentioned indicating device. Background technique [0002] During the operation of minimally invasive surgery, a surgical stapler is usually used to connect adjacent parts of the tissue. Currently, the commonly used stapler with a knife is in the form of a cutting knife added to the surgical fastening device. Linear movement between them, so as to achieve the purpose of cutting and sealing the sutured tissue when the surgical suturing device is sutured. [0003] A typical indicator device of a stapler with a knife. The indicator device is connected to the splint assembly. When working, the initial state indicator device displays green. When the handle is held, the splint assembly drives the indicator device. When the staple cartridge is c...

Problems solved by technology

[0004] During the cutting process, due to the downward movement of the cutting knife, the splint assembly does not move anymore, so the color mark displayed on the indicator device does not change anymore, and the operator cannot observe whether the cutting knife has completed the cutting, and retracts the stapler if the cutting is not completed. Not only does the operation fail, but it may also cause secondary firing, causing secondary injury to the patient; if the cutting is too hard, it will cause damage to the stapler
