Title: SYSTEM AND METHOD TO ESTABLISH CURRENT SETPOINT FOR ULTRASONIC TRANSDUCER
Abstract:
Systems, devices and methods manage surgical instruments throughout their lifecycle by reprogramming a device to account for operational displacement of ultrasonic components based upon a diagnostic test. A diagnostic test tip is used with a surgical instrument to simulate device usage and capture capacitance and phase margin of the device. This information is used to calculate an optimal current to supply to the device during future procedures.
