Transverse stitching instrument for endoscopic surgery

Abstract

The invention provides a transverse stitching instrument for an endoscopic surgery. The transverse stitching instrument comprises a control part, a clamping push rod assembly, a positioning needle push rod assembly, a positioning needle driving assembly and a clamping driving assembly, wherein the positioning needle push rod assembly is arranged outside the clamping push rod assembly in a sleeve manner, the positioning needle push rod assembly is rotationally connected with the positioning needle driving assembly, the positioning needle push rod assembly and the positioning needle driving assembly are axially and relatively fixed and rotated relatively, the clamping push rod assembly is rotationally connected with the clamping driving assembly, the clamping push rod assembly and the clamping driving assembly are axially and relatively fixed and rotated relatively, the control part drives the clamping push rod assembly to rotate to make a clamping part be rotated relative to the clamping driving assembly, and the control part drives the positioning needle push rod assembly to rotate through the clamping push rod assembly to make a positioning needle be rotated relative to the positioning needle driving assembly. The steering of the end part of the stitching instrument is driven by rotating the control part, so that an operator can conveniently control the steering of the end part under the condition that a handheld handle part is not rotated, and therefore the use is convenient.

Description

technical field [0001] The invention relates to a medical device, in particular to a transverse stapler for intracavity surgery. Background technique [0002] The transverse cutting anastomosis / stapler is mainly used for the creation of anastomotic stoma and the closure of the stump or incision in the digestive tract reconstruction and organ resection surgery where it is difficult to expose the surgical field. At present, the general use process of the transverse cutting stapler is: after the locking handle is positioned to lock the tissue, the firing handle is pushed, the cutter hidden in the staple cartridge assembly is pushed by the central rod driven by the firing handle, and the other side of the tissue to be cut is The anvil and the knife pad that provide the tissue cutting platform, the driven straight cutter cuts off the knife pad during the whole cutting process represents the completion of the cutting task. Compared with the transverse cutting stapler, the transve...

However, in the prior art, it is relatively inconvenient to control the direction of the end of the stapler. The operator can only change the direction and angle of the stapler end by changing the direction and angle of the hand. In some cases, the stapler end needs to pass through multiple In the scene where different angles are sutured and the differences between different angles are large, it is very inconvenient for the operator to manually change the angle of the end only by holding it
