Electrosurgical apparatus with the adjustment of the output parameters of the feedback system with optical sensors

摘要

The invention relates to the field of medical technology, namely to electrosurgical devices for dissection and coagulation of biological tissues. Due to the multistage control of electrical signals, including the parameters of the output signal applied to the biological tissue, using the feedback built on the basis of optical sensors, the device is able to control both the total power, on the ECHA load, and the active component consumed by the converter. The control unit of the device optimizes the system's operation mode in accordance with the developed algorithms, by monitoring the reactive power component and interpreting the obtained data into the state and the degree of coagulation of the biological tissue. coagulation without excessive thermal damage, carbonization of adjacent tissues and the risk of complications in the postoperative period.
