AI Technical Summary
Technical Problem
Traditional grinding devices can easily cause bleeding at the affected area during surgery, increasing the difficulty of the operation and prolonging the operation time.
Method used
A bipolar radiofrequency abrasive tool was designed, comprising an outer blade assembly and an inner blade tube. Electrodes are formed by the electrode tube and the outer blade tube, and electrocoagulation hemostasis is achieved through conductive connection. Combined with injection and aspiration channels, electrocoagulation cutting and tissue removal of the affected area are realized.
Benefits of technology
It simplifies the surgical procedure, reduces the use of additional hemostatic instruments, and shortens the operation time.

Abstract
The utility model relates to a bipolar radio frequency grinding cutter and a grinding device, in the using process, a power handle drives an inner cutter tube and a grinding piece to rotate around the axial direction relative to an outer cutter tube, and therefore the grinding piece can be used for grinding and cutting off focus area tissue. When bleeding occurs at an affected part, the main machine supplies power to the electrode tube and the outer knife tube through the conductive plug, so that the electrode tube is electrified to form a pole, the outer knife tube, the conductive part, the inner knife tube and the grinding piece are electrified to form another pole, and the two poles are conducted to form a loop when tissue is contacted. Therefore, electric coagulation hemostasis or electric coagulation cutting can be carried out on an affected part, hemostasis can be carried out on the affected part without additional other hemostasis instruments, operation is easy and convenient, and the operation duration is shortened.
