Self-anastomosing operating handle for surgical operation

Abstract

The invention discloses a self-anastomosing operating handle for a surgical operation. The operating handle comprises a linking rod, a handle shell, a fixed handle and a movable handle. The fixed handle is fixedly connected to the lower side of the handle shell, the movable handle is arranged on the side, facing the output end of the handle shell, of the fixed handle, the top end of the movable handle penetrates an opening formed in the lower side of the handle shell and is rotatably connected in the handle shell through a pin roll, the top end of the movable handle is fixedly connected to a fan-shaped gear, and the fan-shaped gear is in engaged connection to a rack processed and formed on the lower side of the linking rod. Compared with the conventional structure, in which a reset structure is transferred to the fixed handle and the movable handle, the center of gravity of weight of the whole handle structure is transferred, and the space of the inner part of the handle shell is not limited, so that the operating handfeel and the equilibrium sense are improved greatly. In addition, the manufacturing difficulty and cost of the handle are reduced.

Description

technical field [0001] The invention relates to a self-stapler, in particular to a self-staple operating handle for surgery. Background technique [0002] Stapler is a device used in medicine, especially in surgery, 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] Compared with traditional manual suture, instrument suture has the following advantages: [0004] (1) The operation is simple and convenient, saving operation time. [0005] (2) One-time use to avoid cross-infection. [0006] (3) Use titanium nails or stainless steel nails (skin suturing device) to suture tightly and moderately tight. ...

AI Technical Summary

Problems solved by technology

[0008] The stapler mainly includes the head of the titanium nail, the extension in the middle, and the operating handle part. The operating handle is used to operate the firing so that the titanium nail can be ejected and suture the wound, and the doctor is also mainly operating the handle part to carry out the operation. At present, the operating handle structure of the stapler is concentrated inside the shell, which makes the shell highly integrated and the manufacturing cost is also high
