High frequency coagulation in front of the direction for surgical purposes

机译:高频凝结术用于手术目的

摘要

A radio-frequency coagulation device for surgical purposes has a RF generator (29) and a RF power control circuit (20, 21, 25, 31, 32, 33). Furthermore, provision is made of a coagulation instrument (2) having a coagulation head (7) which has a heating head (11) and a passive region (12). A first temperature sensor (16) is arranged in the heating head (11). A second temperature sensor (17) is arranged in the passive region (12) at a predetermined distance from the first temperature sensor (16). The dissipated RF power of a RF generator (29) is regulated via the temperatures measured in the RF power control circuit (20, 21, 25, 31, 32, 33) by means of the temperature sensors (16, 17) in such a way that the size of the clot (coagulum) formed can be regulated precisely.
