Linear cutting anastomat with double security mechanisms

Abstract

The invention relates to the field of surgical medical appliances, in particular to a linear cutting anastomat with double security mechanisms, which can be used for surgical sewing and cutting while loading linear cutting elements. The linear cutting anastomat comprises a closing security mechanism, a triggering security mechanism, a left side plate, a partition plate, a driving plate, a liner, a right side plate, a shell, a closing handle, a triggering handle component, a left support plate and a right support plate; the linear cutting anastomat can load or unload the linear cutting elements; the closing security mechanism comprises a push button, an ejector pin seat, a first pin, a closing security component, a torsional spring and an ejector pin; the closing security component is connected with the torsional spring via the first pin, and a hook on the closing security component stops movement of the partition plate by the aid of torsion of the torsional spring; the triggering security mechanism comprises a spring, a second pin and a triggering security block; and the triggering security block is connected with the spring via the second pin, and a hook on the triggering security block stops movement of the driving plate by the aid of spring force of the spring.

Description

Technical field [0001] The present invention involves the field of medical device for surgery. Specifically, it involves a straight -line cutter with a dual insurance institution, which can load the stitching and cutting of the straight -line cutting element at the same time. Background technique [0002] The linear anastomat also known as a digestive tract closed device, which is a device that can nail multiple seams that can be arranged in the tissue into straight lines. It is also one of the devices that have been widely used to replace handmade straight stitching.It is mainly used to sew the stabilization of the stomach, duodenum, small intestine, and colon, which is a full -layer off -layer stitching. [0003] At present, there is a disadvantage of the traditional straight -line matchmaker, that is, the doctors' operating skills are different, and the surgical type is not consistent. When the positioning needle is not fully inserted into the pad to locate the padAfter pressi...

Problems solved by technology

[0003] At present, there is a shortcoming in the traditional linear stapler, that is, the operating skills of doctors are different, and the surgical procedures are inconsistent. After pressing, there will be overflow at the opening end of the jaws, and the tissue will not be completely enclosed in the positioning needle and the jaws, resulting in the excess tissue not being sutured or cut, thus increasing the risk of manual re-suturing and causing inconvenience to doctors and patients
