AI Technical Summary
Existing radiofrequency electrosurgical systems are prone to excessive heat generation and unnecessary tissue damage during the cutting process, especially in wet environments, making it difficult to achieve precise tissue cutting and coagulation control.
The impedance of the cutting instrument is measured by a radiofrequency electrosurgical generator, and the amplitude of the voltage pulse is reduced when it exceeds a predetermined threshold. Combined with non-uniform pulse groups and recovery period control, the transmission of radiofrequency energy is limited, especially at specific stages of the cardiac cycle. Temperature and impedance are monitored and controlled to optimize the cutting effect.
It enables efficient and precise tissue cutting and coagulation control in a wet environment, reduces thermal damage to adjacent tissues, and improves the safety and effectiveness of the surgery.
