SURGICAL TOOL MONITORING SYSTEM AND METHODS OF USE

摘要

A device for simultaneously monitoring the health of surgical drills and detecting proximity to critical structures during surgery is described herein. By using various sensors (e.g. microphones, accelerometers, temperature sensors, etc.), signals from the drill can be measured and analyzed. The processed signals can then be used to indicate the proximity of the drill bit to critical structures, such as the patient's brain, and identify drill health issues (e.g. worn bearings, misaligned rotational axis, etc.).

1. A surgical tool for cutting tissue in a body, comprising:
a cutting member; at least one sensor configured to provide information about at least one physical condition of the cutting member; and an indicator system that receives the information obtained from the at least one sensor about the at least one physical condition of the cutting member, analyzes the information to detect the approach of the cutting member to a transition from a first tissue type to a second tissue type, and generates a first alert to a user when the cutting member is approaching the transition from the first tissue type to the second tissue type; wherein the at least one sensor comprising one or more microphones to obtain information about an acoustic state of the cutting member.
