Cutting anastomat with self-locking function

Abstract

The invention discloses a cutting anastomat with a self-locking function, and belongs to the technical field of anastomats, the cutting anastomat comprises an anastomat body and a clamping end, wherein the clamping end is arranged at the left end of the anastomat body, the outer side of the clamping end is fixedly connected with one end of a locking mechanism, the other end of the locking mechanism is fixedly connected with one end of a pulling mechanism, the pulling mechanism is fixedly connected to the lower surface of the anastomat body, and a positioning mechanism is arranged on the upper side in the pulling mechanism. According to the device, by arranging the locking mechanism and the pulling mechanism, when a shifting gear rotates, a rack can be driven to move, and the left end of the rack can pull a fixing plate to move; then, the fixing plate pulls one end of the steel wire to move, the other end of the steel wire can pull the fixing block, the fixing block drives the clamping end to move, and the closing effect of the clamping end is more stable; and therefore, the clamping piece can drive the teeth to be clamped into the gear, the effect of positioning the gear is achieved, and closing of the clamping end is not affected.

Description

technical field [0001] The invention belongs to the technical field of staplers, in particular to a cutting stapler with a self-locking function. Background technique [0002] Stapler is a device used in medicine to replace manual suturing. The main working principle is to use titanium nails to separate or anastomose tissues, similar to a stapler. According to the scope of application, it can be divided into skin staplers, digestive tract (esophagus, gastrointestinal, etc.) circular staplers, rectal staplers, circular hemorrhoid staplers, circumcision staplers, blood vessel staplers, hernia staplers , Lung cutting stapler, etc. [0003] The existing cutting stapler used for cutting generally uses the clamping end to clamp the place to be cut, but the clamping material is relatively soft and may loosen during the clamping process, and the stapler may also automatically open and loosen. It brings great inconvenience to people's use, and it is easy to bring risks to the opera...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the existing cutting stapler used for cutting, the place to be cut is generally clamped by the clamping end, but the clamping material is relatively soft, and loosening may occur during the clamping process. The stapler may also be automatically opened and loosened, which brings great inconvenience to people's use and is likely to bring risks to the operation, and the handle of the existing stapler cannot be adjusted. During use, it may be different due to the position of the operating angle. People holding the handle will be greatly restricted, which will have a certain impact on people's operation, and a cutting stapler with self-locking function is proposed.
