Electrosurgery

Background:

Accurate power delivery in electrosurgery is crucial for effective cutting and minimizing collateral tissue damage.
Conventional electrosurgery generators (ESG) rely on surgeon-set, fixed power levels, which may not be optimal, potentially increasing tissue damage.
Gallium nitride (GaN)-based high-frequency inverters (HFI) offer potential for advanced electrosurgical applications.

Purpose of the Study:

To develop and evaluate a real-time feedback control scheme for electrosurgery.
To adapt the electrosurgery generator (ESG) power output dynamically.
To reduce collateral tissue damage during electrosurgical procedures.

Main Methods:

Implementation of a real-time feedback control scheme to adjust electrosurgery generator (ESG) power.
Utilizing an experimental high-frequency inverter (HFI) with a fundamental output frequency of 390 kHz.
Conducting experiments with a gallium nitride (GaN)-based HFI to compare variable vs. fixed power settings.

Main Results:

The proposed adaptive power control scheme successfully adjusted the ESG power in real-time.
Experiments demonstrated reduced collateral tissue damage with the variable-power approach compared to fixed power.
The GaN-based HFI effectively supported the adaptive electrosurgery system.

Conclusions:

A real-time feedback control system can create an adaptive power reference for electrosurgery.
This adaptive approach offers a significant advantage in reducing collateral tissue damage over conventional fixed power settings.
Gallium nitride (GaN) technology is suitable for developing advanced, adaptive electrosurgical devices.
