CIRCUIT FOR RADIO-FREQUENCY DEVICES, APPLIED FOR LIVE TISSUES, AND DEVICE CONTAINING SAID CIRCUIT Russian patent published in 2012 - IPC A61B18/12 H03H1/00 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment, namely to radio-frequency devices for influence on live tissues. Circuit for power supply to electrodes of device, which includes electric scalpel and/or device for diathermy by passing current with frequencies from 100 kHz to 10 MHz contains resonance successive filter and resonance parallel filter. Resonance successive and parallel filters are syntonised to ensure passing through themselves main frequency of inlet signal, and simultaneously exponential decay of remaining harmonics with increase of frequency of harmonics. Resonance successive and parallel filters are divided with transformer TRF, tuned to radio-frequency, with transformation coefficient 1:N, where N is a real number. Circuit is used in device for diathermy and electric scalpel.

EFFECT: application of invention makes it possible to reduce disturbance to other electronic equipment.
