Description

Planing power system

Technical Field

The invention relates to a planing power system, and belongs to the technical field of medical instruments.

Background

With the progress of medical technology, the application of minimally invasive technology is more extensive. Minimally invasive techniques, which are techniques that achieve optimal surgical efficacy with minimal invasion and minimal physiological interference, have the advantages of small surgical incision, short recovery time, and the like.

The medical planing power system is used for minimally invasive endoscopic surgery, and the planing head of the medical planing power system is a rotary planer consisting of an inner rotating part and an outer fixing part with a window; is an operation power device used for planing human tissues and soft tissues in surgery, orthopaedics or otorhinolaryngology and cosmetic operation. The power supply is controlled by the host machine, electric energy and signals are transmitted to the power-driven hand tool through a cable, and the hand tool is internally provided with a motor to drive a cutter to rotate so as to finish the planing treatment of human tissues; the suction force is generated by a negative pressure device arranged in the main machine, and the human tissue processed by the planing is discharged out of the body through a channel in the cutter. The system is divided into three working states of standby, suction and planing, wherein the cutter does not work in the standby state, and the vacuum pressure of the working end of the hand tool is zero; the cutter does not work in the suction state, and the working end of the hand tool keeps vacuum pressure; the tool works in a planing state, and the working end of the hand tool is under vacuum pressure. When in use, the outer tube of the planing knife is tightly attached to the part to be cut and fixed to determine the window range of surgical cutting, thereby avoiding the accidental damage of surrounding tissues. In the cutting process, after the main machine is started, the inner tube of the planing cutter rotates at a high speed, and a cutter head of the inner tube generates strong shearing force or grinding force to grind tissues. However, when the inner pipe of the planing tool used at present rotates, the supporting force is insufficient, and the situation of radial run-out exists, so that the stable use of the tool bit is influenced; and the excised tissue will partially accumulate at the incision, causing blockage at the incision, thereby affecting the efficiency of the operation.
