Osculating assembly steering device of electric endoscope anastomat

Abstract

The invention relates to the technical field of medical instruments, in particular to an osculating assembly steering device of an electric endoscope anastomat, which is matched with the electric endoscope anastomat for use and is suitable for local incision anastomosis in the aspects of human bodies, gastrointestinal tracts, gynecology, thoracic departments and the like. The device comprises a steering joint, a steering shifting piece, a connector, a steering pin block, a steering joint fixing block, a steering pin block spring, steering drag hooks, an oscillating handle, an oscillating gear,a rotating handle and oscillating transmission racks. An osculating assembly is connected with an osculating assembly mounting hole of the steering joint through a pin; the front end of a connectingrod is connected with the connector through a connecting rod mounting groove of the connector; the two steering drag hooks are clamped on the two sides of the connecting rod respectively, connected with the two oscillating transmission racks, and sleeved with the fixed sleeves; and the upper half portion and the lower half portion of the rotating handle are sleeved on the two sides of the fixed sleeves. The angle of the osculating assembly can be accurately adjusted during an operation, the operation implementation position can be better controlled, the operation safety is improved, and the success rate of the operation is increased.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a steering device for an anastomotic cutting component of an electric endoscopic stapler used in conjunction with the electric endoscopic stapler, which is suitable for medical treatment of the human body, gastrointestinal tract, gynecology, and chest. Partial cutting and anastomosis. Background technique [0002] In actual use at present, there are mainly two types of endoscopic staplers. One is a manual endoscopic stapler and the other is an electric endoscopic stapler. The manual laparoscopic stapler mainly relies on the rack and the firing pusher to realize the advancement of the cutting knife, and the retreat needs to be pulled back manually. The opening and closing of the staple cartridge assembly depends on the knife pin on the cutting knife to push the slope on the abutment seat to realize the opening and closing of the abutment seat. The overall structure is r...

Problems solved by technology

At present, the steering device of the anastomotic cutting component of the electric endoscopic stapler is forced to turn by compressing the tissue. If there is no tissue or the steering cannot be turned in the cavity, if the force is too strong during the forced steering, it will scratch the tissue and bring risks to the operation.

[0004] It can be seen that the above-mentioned existing endoscopic stapler obviously still has inconvenience and defects in structure, method and use, and needs to be further improved urgently.
