Fine adjustment mechanism capable of reducing losses for stapler

Abstract

The invention discloses a fine adjustment mechanism capable of reducing losses for a stapler, and belongs to the technical field of medical instruments. According to the technical solution, the fine adjustment mechanism is characterized by comprising a shell, a battery, a microcontroller, a driving mechanism and an adjusting mechanism; the microcontroller is used for controlling the adjusting mechanism; the shell includes a shell body and a grip connected with the shell body; the battery is arranged in a battery cavity in the tail portion of the shell body; the adjusting mechanism is arranged in the shell body; the driving mechanism is arranged in the grip, is matched with the adjusting mechanism, and is used for driving the adjusting mechanism to realize gear shifting on equipment; the shell body is further provided with a transmission mechanism; and one end of the transmission mechanism is provided with a power head connection part extending out of the shell body. The fine adjustment mechanism saves the internal space of a handle, the applicability of the handle is improved, and in addition, losses of a transmission part can be effectively reduced, 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...

AI Technical Summary

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.
