A fine-tuning mechanism for reducing loss of stapler

Abstract

The invention discloses a fine-tuning mechanism capable of reducing losses of an anastomat, which belongs to the technical field of medical devices. An adjustment mechanism, the housing includes a housing body and a handle connected to the housing body, the battery is arranged inside the battery cavity at the rear of the housing body, the adjustment mechanism is arranged inside the housing body, and the driving mechanism is arranged on the handle It is used to drive the adjustment mechanism to realize gear shifting of the equipment. The housing body is also provided with a transmission mechanism, and one end of the transmission mechanism is connected to a power head extending out of the housing body. Part, the present invention saves the space inside the handle, increases the applicability of the handle, and can effectively reduce the loss of the transmission parts, so that the service life of the stapler handle is longer.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a fine-tuning mechanism for a stapler that can reduce loss. Background technique [0002] At present, laparoscopic cutting staplers are mainly divided into three types: disposable manual laparoscopic cutting stapler, disposable electric laparoscopic cutting stapler, and electric cutting stapler. Instability, poor 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. [0003] In view of the above shortcomings, an electric cutting stapler has been developed. Its power handle is mainly composed of a shell, a motor, a power transmission mechanism, a battery, etc., and the battery is used to provide power...

Problems solved by technology

[0002] At present, laparoscopic cutting staplers are mainly divided into three types: disposable manual laparoscopic cutting stapler, disposable electric laparoscopic cutting stapler, and electric cutting stapler. Instability, poor 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

[0003] In view of the above shortcomings, an electric cutting stapler has been developed. Its power handle is mainly composed of a shell, a motor, a power transmission mechanism, a battery, etc., and the battery is used to provide power for the motor to drive the actuator of the power handle to complete the operation. Solved the problems of laborious operation and high cost of use, but there are still defects

[0004] According to the power handle of the stapler whose publication number is CN 109419546 A, the handle uses a plurality of motors to drive the power head respectively, thereby realizing the versatility of the handle, but in the actual transmission process, the use of a plurality of motors consumes a large amount of energy. The installation space and the small size of the stapler handle itself will easily lead to the oversize of the stapler. At the same time, although the above technology has designed three motors to drive the three power heads respectively, the scope of application is only related to the number of motors. The motor undoubtedly further increases the size of the handle. In addition, due to the use of conventional gears for transmission, and the gears are easy-to-wear parts in the transmission parts, the service life of the power handle of the stapler is greatly reduced.
