Abstract

The invention provides a stitching instrument. The stitching instrument comprises a locking mechanism of a firing handle. A first bump is arranged on a firing lock sheet of the locking mechanism and used for dividing a part uncovered with the first bump on the firing lock sheet into a first part and a second part; and the first part and the second part form a barrier-free channel. According to the stitching instrument, the structure of the locking mechanism of the coking handle is changed, particularly the structure of the firing lock sheet is changed, the bump on the firing lock sheet does not block downward sliding of a locking part, and the barrier-free channel in the firing lock sheet enables the locking part to smoothly slide out of the firing lock sheet, so that the risk that the locking part cannot slide out of the firing lock sheet in the prior art is avoided.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a stapler with a locking mechanism of a firing handle. Background technique [0002] In the surgical operation of medical science, since the first staple product in the 1960s, the medical linear stapler has become an indispensable medical device in the process of suturing the knife edge. Various surgical linear staplers are widely used in surgical operations to suture human digestive tract tissues, respiratory tract tissues and vascular tissues, which can reduce operation time and improve operation quality. They are usually used for end-to-end, end-to-side, and side-to-side suture operations such as esophagus, stomach, duodenum, small intestine, colon, and rectum in the digestive tract, or operations for forming channels or closing incisions such as hemorrhoidectomy and gastric pylorostomy. It is used in the suture operation of the lung and trachea in the respiratory tract and...
