Embodiment 1

[0015] Such as figure 1 As shown, the surgical power tool that can collect bioelectrical impedance in real time is formed by adding a bioelectrical impedance collection unit on the basis of the existing surgical power tool. The copper wire brush clamping mechanism 2 on the cutting tool of the power tool 1, the electrode sheet 5 attached to the skin near the operation area, the copper wire brush clamping mechanism and the electrode sheet are respectively connected to the impedance analysis instrument 8 with the coaxial cable 3. The present invention uses a double-electrode method to measure impedance (disposable electrode sheet 5 and copper wire brush clamping mechanism 2), and the frequency range of electrical impedance measurement is 200KHz-1MHz.

[0016] In the figure, 1 is a surgical power tool, 2 is a copper wire brush clamping mechanism, 3 is a coaxial cable, 4 is a saline nozzle, 5 is a disposable electrode piece, 6 is a bone to be cut, and 7 is an operating bed. 8 is ...

Abstract

A surgical power tool that can collect bioelectrical impedance in real time is formed by adding a bioelectrical impedance collection unit on the basis of existing surgical power tools. The bioelectrical impedance collection unit includes a surgical power tool clamped in a high-speed rotation The copper wire brush clamping mechanism on the cutting tool of the tool, the electrode sheet attached to the skin near the operation area, and the copper wire brush clamping mechanism and the electrode sheet are respectively connected to an impedance analysis instrument with a coaxial cable. According to the relationship between the measured electrical impedance value and the infeed depth, it can be estimated which bone tissue the end of the tool is in. The invention can measure the bioelectrical impedance of the tissue in real time, thereby improving the operation safety of the operation power tool and having high sensitivity.

Description

technical field [0001] The invention belongs to the technical field of medical auxiliary equipment, and in particular relates to a surgical operation power tool capable of collecting bioelectrical impedance in real time. Background technique [0002] During orthopedic surgery, doctors often use surgical power tools to expose or remove the lesion. Traditional surgical power tools output controllable mechanical kinetic energy to drive grinding heads, drills and other instruments to complete the operation. During the use of surgical power tools, the technical parameters of bone grinding (including feed rate, cutting depth and cutting speed, etc.) ) is completely controlled by the surgeon himself, so the flexible use of the tool must rely on the doctor's long-term experience and experience accumulation. The working space of many orthopedic surgeries is relatively narrow, and there are certain pathological and anatomical variations between individuals. Normal tissues are affecte...
