BIPOLAR COMBINATION DEVICE THAT AUTOMATICALLY ADJUSTS PRESSURE BASED ON ENERGY MODALITY

Smart overview of the Invention

A surgical instrument system is designed to adjust the compression force applied during surgery. This adjustment is based on the tissue impedance detected by the end effector of the instrument. The device selects and applies different energy modalities, generating corresponding signal waveforms to optimize the energy delivery to the tissue. By altering the gap size between the tissue and the clamp arm, the system automatically adjusts the compression force according to the energy modalities used.

Methodology

The method involves a control circuit that determines the tissue type by measuring tissue impedance. Once identified, the circuit selects a suitable energy modality and generates a signal waveform. It then selects a second energy modality, generates another waveform, and delivers both to the end effector. The compression force is adjusted by modifying the gap size between the end effector and the tissue, based on the ratio between the two signal waveforms.

System Components

The surgical system includes a surgical hub connected to a cloud computing system, which provides tissue treatment algorithms. The surgical instrument, connected to this hub, consists of an end effector with a clamp arm and an ultrasonic blade. A generator supplies multiple energy modalities to the end effector, while a control circuit manages the energy delivery and compression force adjustments. This integration ensures precise and effective tissue treatment.
