Abstract
A radio frequency coagulation instrument has two concentric tubular feedls (15, 16) with coagulation electrodes (13, 14) at their end. The tubular feedlines (15, 16) are simultaneously used to supply the radio frequency current to the coagulation electrode (13, 14) and for the supply and removal of a flushing liquid. Moreover, the passage (19) formed within the tubular feedline (16) which serves for the removal of flushing liquid, and which is expediently connected to a vacuum source, can be used independently of the supply of flushing liquid to suck away not only flushing liquid but also, or alternatively, blood, body fluids, secretions and pieces of body tissue.
