The electrosurgical system described features an end effector assembly with jaw members designed to grasp and treat tissue. These jaw members possess tissue-contacting surfaces that can move between spaced-apart and approximated positions. Integrated light elements project onto the tissue, and a generator supplies electrosurgical energy to these surfaces for treatment. The system is equipped with sensors to gather data from the light elements, aiding in the control of energy supply and predicting thermal spread.
The generator includes a controller that manages energy delivery to the tissue, predicts thermal spread beyond the jaw members, and adjusts the light projection when thermal spread exceeds a certain threshold. This is crucial for minimizing unintended heating of tissues outside the targeted area. The sensors, placed on or near the jaw members, provide real-time data that informs these adjustments.
The system employs light-emitting diodes (LEDs) that project light onto tissue. These LEDs can vary in intensity, pattern, angle, or color to optimize tissue treatment and monitoring. The LEDs may differ in size and shape along the jaw members, enhancing their functionality in different surgical contexts.
Sensors integrated into the system collect various types of data, including temperature, electrical feedback (such as power, voltage, current, and impedance), tissue hydration, thickness, type, and mass. This data is crucial for predicting thermal spread and adjusting the LEDs accordingly to ensure precise treatment.
The system features a housing with a shaft extending to an end effector assembly at its distal end. The jaw members define electrically-conductive surfaces for tissue contact. LEDs are positioned around these surfaces or at the distal end of the shaft to project light effectively. The controller uses sensor data to dynamically adjust LED settings, thereby optimizing surgical outcomes while limiting thermal damage to surrounding tissues.
