Single-motor electric surgical instrument hand-held assembly and electric surgical instrument

Abstract

The invention relates to a single-motor electric surgical instrument hand-held assembly and an electric surgical instrument. The single-motor electric surgical instrument hand-held assembly comprises:a power supply module, a driving module, a switching module, a first power output module, a second power output module, a control circuit and a housing part. The switching module can be meshed with the driving module to obtain power input, the switching module comprises a shaft, a first gear and an output switching part, the first gear is arranged on the shaft, and is meshed with a driving gear of the driving module, the output switching part is coupled with the first gear, the switching module is meshed with the driving gear of the driving module, and the switching module can be in a first output mode or a second output mode by shifting the output switching part. According to the invention, the structural complexity of the electric surgical instrument is reduced and the cost is saved. Meanwhile, through setting an initial driving state, a safety structure for preventing false triggering is formed.

Description

technical field [0001] The invention relates to a medical surgical instrument, in particular to a hand-held assembly of a single-motor electric surgical instrument and a single-motor electric surgical instrument using the hand-held assembly. Background technique [0002] In surgery, staplers are usually used to resect tissues and seal wounds. Staplers include linear cutting staplers, tubular staplers, endoscopic linear cutting staplers, etc. These staplers can be used to resect diseased tissues of the lung, intestine, and stomach while sealing the wound. During the operation, the end effector of the stapler clamps and squeezes the tissue, then cuts the tissue with a cutting knife, and quickly sutures the wound with staples. The use of the stapler shortens the operation time, improves the success rate of the operation, and recovers quickly after the operation. [0003] The currently used stapler mainly has two kinds of manual operation and electric operation. During the o...

AI Technical Summary

Problems solved by technology

The operation action of the electric stapler includes the closing and firing of the staple cartridge assembly, the swinging movement of the staple cartridge assembly and the rotation of the staple cartridge assembly around its own axis. The power sources of multiple motors control each action separately, and the corresponding power transmission system needs to be installed in the stapler, resulting in high cost, heavy weight and complex structure of the electric stapler
