Adaptive advanced tissue therapy pad saver mode

摘要

A method of controlling the temperature of an ultrasonic blade between two temperature setting points isTo set the ultrasonic blade temperature to a first target temperatureApplying a first power level to the ultrasonic transducerThe phase angle between the voltage VG (T) applied to the transducer and the current Ig (T) signal φ AndPhase angle φ Guess blade temperature based onDetermine that the lateral incision process has been completed.To set the blade temperature to the second target temperatureApplying a second power level to the transducer.The transducer may be coupled to the blade via an ultrasonic waveguide.The first target temperature may be optimized for vascular sealing, and the second target temperature may be optimized for the duration of the clamp arm pad.The control circuit may determine that the lateral incision is completed by determining that the ultrasonic blade is in contact with the clamp arm pad.
