VerteMeasure: An Efficient Spinal Bone Impedance Measuring System for Surgery Assistance

This paper presents VerteMeasure, an efficient system designed for measuring human spinal bone impedance. VerteMeasure is capable of discerning the type of spinal bone and detecting if any abnormal issues like bleeding occur during the surgery. The screwdriver-like device includes a main control system, screw-like probe tips connected to the electrode terminals, and easy-to-use handles. The main control system provides a switch signal to the switch current source circuit to generate excitation to the electrode terminals. The voltage signal of the switch current source enters the human spinal bone through the electrode terminals, and the response signal of the electrode terminals is transmitted to the main control system to decide the impedance. By comparing the measured signal with the signal of the normal human spinal bone impedance, the type or the status of spinal bone can be distinguished. The system has been designed as a product and validated through a set of experiments to ensure its effectiveness.
