Anastomat with automatic reset safety mechanism, for gastroenterology department

Abstract

The invention discloses an anastomat with an automatic reset safety mechanism, for gastroenterology department, and belongs to the technical field of medical instruments. The anastomat comprises an operating handle, a rod body, a nail head assembly, a fixing assembly, a connecting assembly and a transmission rack, wherein a mounting sleeve is mounted at one end of the operating handle in a threaded mode, and a holding rod is fixedly mounted at the bottom of the operating handle. According to the anastomat, an inner sleeve shaft is mounted in a rod body penetrating into the operating handle, a safety reset spring is mounted outside the inner sleeve shaft, when the anastomat is used normally, an operating rod is directly pressed, the operating rod can drive a movable clamp to move, certain extrusion is generated on the safety reset spring, and the safety reset spring is compressed. At the moment, the inner sleeve shaft can drive the transmission rack to move, the nail head assembly is controlled to work through the gear meshing effect, when operation is not needed, the safety reset spring can automatically drive the structure to reset due to the reset effect of the safety reset spring, the good safety reset effect is achieved, manual adjustment reset is not needed, and the operation efficiency is improved.

Description

Technical field[0001]The present invention belongs to the technical field of medical devices, and more particularly to a digestive internal medicine with an automatic reset insurance mechanism.Background technique[0002]With the rapid development of the medical industry, various medical devices have also been rapidly produced. Different medical devices have different medical effects, with anastomotive, and more important, and the anastomotic is the world. The first sewer. The stapler is generally divided into a disposable or multi-use stapler, imported or domestic anastomotic. It is a medical replacement of traditional manual sewing equipment. Due to the improvement of modern technology development and production technology, the quality of the stapler use of clinical use is reliable, easy to use, strict, tight, especially its stitching, simple operation and There are very few advantages such as side effects and surgical complications, but also caused to remove tumor surgery in the pa...

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that traditional staplers are generally integrated and cannot be disassembled to a certain extent, when the shaft of the stapler fails, it cannot be repaired in time, and there is no adjustable device The rapid disinfection structure needs to be processed through disinfection steps before the operation, which reduces the operation efficiency. At the same time, the traditional stapler is not equipped with an automatic reset safety structure. During the operation, after suturing, the plug assembly needs to be manually reset, which is troublesome. Moreover, it is impossible to maintain the sutured state. If there is a misoperation in the operation, there will be a huge problem of medical accidents. A gastroenterology stapler with an automatic reset safety mechanism is proposed.
