Surgical instrument and operation method thereof

Abstract

The invention provides a surgical instrument and an operation method thereof. The surgical instrument may comprise a power output device, a driving shaft, a transmission shaft, a scalpel head, an adsorption device and a feedback device, wherein the driving shaft is connected with the powder output device; one end of the transmission shaft is connected with one end of the scalpel head, and the other end of the transmission shaft is connected with the adsorption device; the transmission shaft and the scalpel head are both of tubular structures; the feedback device is arranged on the scalpel head and connected with the power output device. According to the scheme, the power output device outputs power for a gear corresponding to operation and maintenance information, the scalpel head rotates and reciprocates, and therefore excision of abnormal tissue under a blade can be realized; due to the fact that the rotating speed and reciprocating speed of the scalpel head are relevant to the power of the power output device, the scalpel head can enter the abnormal tissue to completely cut off the abnormal tissue while rotating and reciprocating rapidly.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a surgical instrument and an operating method thereof. Background technique [0002] With the continuous development of medical technology, more and more difficult-to-cure diseases can also be cured through surgery. In the current surgical operation, after the abnormal tissue of the patient is determined, the medical staff generally use a traditional scalpel to remove the abnormal tissue of the patient through their own strength. However, during the resection process, due to the low strength of the medical staff and the slow cutting speed, there may be residual abnormal tissue. For some diseases, if complete resection cannot be achieved, abnormal tissue may continue to grow , affect the patient's surgical outcome. Contents of the invention [0003] Embodiments of the present invention provide a surgical instrument and an operating method thereof, so as to complete...
