FIELD: medicine. ^ SUBSTANCE: invention relates to medical equipment and can be used in surgery for dissection and coagulation of soft tissues of organism. Electric system for oncosurgery contains control unit, connected through unit of electrosurgical action with active electrode, current metres, through them with passive electrodes and with current ratio calculator and comparator, with connected to it constant memory unit. In addition system contains connected with each other multi-frequency impedance metre, differentiator, tact generator and decoupler. Multi-frequency impedance metre is connected with its one inlet/outlet through decoupler with active electrode, second outlet of multi-frequency impedance metre is connected through differentiator to comparator. To comparator outlet unit of electrosurgical action is connected; tact generator is connected to inlet of multi-frequency impedance metre, to inlet of decoupler, to comparator and to outlet of unit of electrosurgical action. ^ EFFECT: possibility to constantly estimate structure, physiological state of biotissue and to determine level of optimal electrosurgical action intensity. ^ 3 cl, 3 dwg |
