Abstract

The invention relates to a safety device for an anastomat. The safety device comprises a fixed handle, a movable handle, a safety lever, a safety pushing button and a support handle, wherein the safety lever is fixedly connected with the safety pushing button and the safety lever and the safety pushing button are slideably arranged at one end of the support handle, the other end of the support handle is fixed on the fixed handle, and a clamping groove where the safety lever can be inserted in a matching manner is arranged at one end of the movable handle, which is abutted with the support handle. The safety lever can move along a prescribed trajectory in a certain angle range, and can open or close the movable handle after reaching a certain position. The safety device for preventing the anastomat from abnormally firing can prevent operation failure caused by accident or abnormal firing, is simple in structure, convenient for assembly and safe in use, and plays an important role in correctively using the anastomat, thereby being suitable for popularization and application.

Description

technical field [0001] The invention relates to a tubular stapler, in particular to a stapler safety device specially used for digestive tract operations. Background technique [0002] In surgical operations, medical staplers have become an indispensable auxiliary medical device in the process of suturing human tissue. Among them, the circular stapler is used for end-to-end, end-to-side, and side-to-side anastomosis in digestive tract lumen surgery. It provides two rows of annular staples spaced from each other. Shaped anastomosis. The application of medical stapler has many advantages such as less blood loss during operation, shorter operation time, reduction of manual operation error, avoidance of infection, and quick recovery of postoperative function. [0003] At present, the anti-misfire insurance of more tubular staplers used clinically mostly adopts the method of adding brackets at the root of the movable handle to prevent accidental firing of the instrument. This ...
