ELECTRIC SURGICAL SCALPEL Russian patent published in 1999 - IPC

Abstract RU 2131222 C1

FIELD: medical engineering. SUBSTANCE: scalpel has case containing power supply source, high-frequency generator and control unit. Operating part with active and neutral electrodes is connected to high-frequency generator. Neutral electrode circuit includes capacitor, amplifier, comparator, and galvanic decoupling unit. Amplifier input is connected to capacitor, and its output is connected to first input of comparator. Preset level of signal is supplied to second input of comparator from control unit through galvanic decoupling unit. Scalpel extends functional capabilities in operative interventions due to control of output power of high-frequency generator and maintenance of electric arc size on level set up by surgeon. EFFECT: reduced thermal traumatization of tissues. 1 cl, 7 dwg
