Stapler power handle

Abstract

The invention provides a stapler power handle. The power handle comprises a housing, a power mechanism and a battery. The housing comprises a housing body and a handle connected with the housing body,the power mechanism comprises a first power unit and a second power unit, the first power unit is arranged in the front middle part of the housing body, the second power unit is arranged in the handle, and the battery is arranged at the inner rear part of the housing. According to the stapler power handle, the power mechanism is arranged in the handle and the housing body respectively, handle space is fully utilized, the structure is simplified to prevent gathering, the installing and heat dissipating of the power units are facilitated, the battery is arranged in the tail part of the housingbody, and the purpose of front and back balancing is achieved.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a power handle of a stapler. Background technique [0002] At present, laparoscopic cutting staplers are mainly divided into three types: disposable manual laparoscopic cutting staplers, disposable electric laparoscopic cutting staplers, and electric cutting staplers. [0003] Among them, the disposable manual laparoscopic cutting stapler has the problems of laborious operation, unstable anastomotic cutting, poor forming consistency of titanium nails and high cost of use. For the disposable electric laparoscopic cutting stapler, the same handle can only replace the staple cartridge of the same length model, which is not universal; the handle is scrapped after using the manual emergency retraction function, and the one-time use cost is high. [0004] In view of the above shortcomings, an electric cutting stapler has been developed. Its power handle is main...

AI Technical Summary

Problems solved by technology

Although the problems of laborious operation and high cost of use have been overcome, there are still defects:

[0005] 1. The multiple motors used to drive the stapler for cutting, stapling, bending and rotating are all arranged on the upper part of the housing. The structural arrangement is complex and the transmission mechanisms are numerous, which increases the volume of the upper part of the housing and makes the entire power handle heavy.

[0006] 2. Multiple motors are clustered on the upper part of the casing, which generates a lot of heat, and it is not easy to dissipate heat in the closed casing, which affects the normal operation of other components such as electronic components

[0007] 3. The battery is installed at the lower end of the grip part of the handle of the shell. When holding it, the lower end feels heavy, unbalanced front and rear, and inconvenient to operate.

[0008] 4. The process of cleaning, disinfection and sterilization after use is complicated, and the handle as a whole cannot be sterilized by high-temperature cooking

The handle shell is a one-time use detachable structure. Every time it is used, the shell needs to be sterilized and sterilized separately, and then the shell is installed on the handle for surgery. After the operation, the used shell will be scrapped. Replacing a new sterilized shell during use, on the one hand, it is troublesome to install and disassemble, and on the other hand, the disposable shell increases the cost of use; in addition, the handle structure as a whole cannot be sterilized at high temperature, and there is a risk of infection caused by insufficient sterilization
