A transverse stapler for intracavitary surgery

Abstract

The present application provides a transverse stapler for intraluminal surgery, comprising a control member, a clamping push rod assembly, a positioning needle push rod assembly, a positioning needle driving assembly and a clamping driving assembly, and the positioning needle push rod assembly is sleeved on the clamp Holding the outside of the push rod assembly, the positioning needle push rod assembly and the positioning needle drive assembly are rotatably connected, and the positioning needle push rod assembly and the positioning needle drive assembly are axially relatively fixed and rotate relative to each other, clamping the push rod assembly and the clamp The holding and driving assembly is connected in rotation, and the axial direction between the clamping push rod assembly and the clamping driving assembly is relatively fixed and the two rotate relative to each other, and the control member drives the clamping push rod assembly to rotate to make the clamping member rotate relative to the clamping driving assembly, And the control member drives the positioning needle push rod assembly to rotate through the clamping push rod assembly, so that the positioning needle rotates relative to the positioning needle driving assembly. The steering of the end of the stapler is driven by the rotating control member, which is convenient for the operator to control the steering of the end without the hand-held handle part being rotated, and is convenient to use.

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...

Problems solved by technology

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
