Surgical power tool capable of acquiring bioelectrical impedance in real time

Abstract

The invention relates to a surgical power tool capable of acquiring bioelectrical impedance in real time. A bioelectrical impedance acquisition unit is added on the basis of the existing surgical power tool to form the surgical power tool. The bioelectrical impedance acquisition unit comprises a copper wire brush clamping mechanism which is clamped on a cutting tool of a surgical power tool which rotates at a high speed, and an electrode pad adhered to the skin next to a surgical area, wherein the copper wire brush clamping mechanism and the electrode pad are respectively connected with an impedance analysis instrument by coaxial cables. According to the relationship between the measured electric impedance value and a feed depth, the kind of bone tissue the tail end of a tool is positioned in can be estimated. The bioelectrical impedance of the tissue can be measured in real time, thereby the operating safety of the surgical power tool can be improved, and the sensitivity is higher.

Description

Technical field [0001] The present invention is a medical auxiliary device technology field, which involves a surgical power tool that can collect biological impedance in real time. Background technique [0002] Surgery surgery is often exposed or removed with surgical dynamic tools.Traditional surgical power tools through output -controlled mechanical kinetic energy, driving grinding heads, drills and other instruments to complete surgery. During the use of surgical power tools, bone technical parameters (including feed, cutting depth, and cutting speed, etc.) It is completely mastered by the surgeon, so the flexible use of the tool must rely on the long -term experience and experience accumulation of the doctor.Many orthopedic surgery work space is relatively narrow, and there are certain pathological variations and anatomical mutations between individuals. Normal tissue is affected by lesions and is difficult to identify. The high -speed rotating head or drill head during surg...
