[Principles in the designing of an impedance electrosurgical apparatus for reliable resection of oncologic tumors and involved biological tissues].
The paper proposes that for more reliable resection of cancer tumors and involved biological tissues during a surgical intervention, the structure of biological tissues should be evaluated by measuring its impedance at two frequencies: 2 and 440 KHz and by calculating the polarization coefficient (Cpolar). Examining Cpolar changes in intact and pathologically altered biological tissues allowed them to be distinguished during a surgical intervention by employing an impedance electrosurgical apparatus.
