Abstract

The invention provides a device and method of determining a cutting head work state. The device comprises a cutting head, a light emitter, a light sensor, a light shielding device, a signal generating unit and a processing unit, wherein the light emitter emits light rays; the cutting head reciprocatingly move along a central axis; the light shielding device shield light rays or enables the light rays to permeate when the cutting head moves to different positions via reciprocating movements; when light rays are not shielded by the light shielding device, the light sensor receives the light rays emitted by the light emitter; the signal generating unit generates a corresponding pulse signal according to a light receiving condition of the light sensor, and outputs the pulse signal; and the processing unit determines a current work state of the cutting head via the output pulse signal. Therefore, a work state of the cutting head can be determined.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a device and method for determining the working state of a cutter head. Background technique [0002] With the development and progress of science and technology, minimally invasive laparoscopic surgery is widely used in various surgical treatment fields. Through small incisions, laparoscopic surgical instruments can be inserted inside the body and manipulated outside the body to perform surgery. For example, in one application, a scalpel tip in a surgical instrument may be manipulated to remove a tumor. [0003] At present, the power output by the external power source can be used to perform surgical operations through the cutting action of the scalpel head. [0004] When the cut tissue fragments get stuck near the cutter head and are not sucked out normally, the resistance on the cutter head will easily increase and affect the surgical effect, and even the cutter head may be...
