Abstract

The invention discloses a safety device of a surgical operating instrument. The safety device comprises a shell, a hitting handle, a safety block and a limiting part. A base is arranged in the shell. The hitting handle rotates relative to the shell. The safety block is axially connected with the shell through a first rotating shaft in a rotating mode. The safety block comprises a first end and a second end. The limiting part is located in the base. The first end of the safety block makes contact with the limiting part. When the safety block axially rotates in the shell, the first end is clamped at a first position formed between the limiting part and the base, and the hitting handle abuts against the second end; when the first end is clamped at the second position formed between the limiting part and the base, the hitting handle is disengaged from the second end. The safety device is remarkable in safety effect, clear in action pointing in the operation process, ingenious in structure and high in stability and has a clear voice prompting function.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a stapler with a safety device. Background technique [0002] In surgical operations, medical staplers have become an indispensable medical device in the process of anastomosis of human tissues. With the development of medicine and product research and development, more and more multifunctional stapler products are used in clinical practice, and the scope of application has involved stomach Intestinal surgery, hepatobiliary surgery, thoracic surgery, urology, gynecology and other fields have become one of the indispensable surgical tools for doctors. The application of medical stapler has many advantages such as less blood loss during operation, shorter operation time, reduction of manual operation error, and quick recovery of postoperative function. [0003] The stapler in the prior art, taking the tubular stapler as an example, includes an outer safety, a straight ...
