Anastomosis cutting driving device of one-step linear cutting anastomat

Abstract

The invention relates to an anastomosis cutting driving device of a one-step linear cutting anastomat. The anastomosis cutting driving device supports the one-step linear cutting anastomat, and the supported one-step linear cutting anastomat is applicable to local cutting of trunk, gastrointestinal tract, gynecology, chest and the like and can achieve suture anastomosis of residue tissues on both sides of an excised part. The anastomosis cutting driving device comprises a pushing handle I, a pushing handle II, a pushing handle installation positioning block, a pushing block, a security block, a security pin, a spring, a push rod, a push rod guide block and a cutter and staple pushing plate driving block module. The front end of the push rod is provided with a cutter boss, and the rear end of the push rod is provided with a pushing block hook; the cutter and staple pushing plate driving block module is composed of a cutter and a staple pushing plate driving block which are assembled into a whole through injection molding to form the cutter and staple pushing plate driving block module; the pushing handle I and the pushing handle II are mounted inside the pushing handle mounting grooves of the pushing handle installation positioning block and positioned through positioning pins.

Description

technical field [0001] The invention relates to a cutting driving device of a disposable linear cutting stapler, which is a cutting knife and a staple driving component pushing part matched with the disposable linear cutting stapler. After matching, the disposable linear cutting stapler is suitable for Partial cutting in the human body, gastrointestinal tract, gynecology, chest, etc., and suture and anastomose the tissues left on both sides of the excised part. Background technique [0002] At present, the push handle of the disposable linear cutting stapler is set as a whole and the volume is relatively large. It is not convenient to use when pushing the cutting knife, moving forward and backward. Usually, the cutting knife is installed at the front end of a push rod, and the push block of the nail pusher is set. At the front ends of multiple different push rods, multiple push rods are fixed on the push block and pushed by the push handle. During use, the gap between the cu...

[0002] At present, the push handle of the disposable linear cutting stapler is set as a whole and the volume is relatively large. It is not convenient to use when pushing the cutting knife, moving forward and backward. Usually, the cutting knife is installed at the front end of a push rod, and the push block of the nail pusher is set. At the front ends of multiple different push rods, multiple push rods are fixed on the push block and pushed by the push handle. During use, the gap between the cutting knife and the push piece is relatively large, which is easy to shake, the resistance is relatively large, and the cut tissue wound is not smooth.
