ABSTRACT:
An apparatus for argon-plasma coagulation (APC) is disclosed, in which after activation of the apparatus for APC a specified amount of noble gas flows out of the APC instrument before the high-frequency voltage for ionizing the noble gas is switched on, or can be switched on. As a result an increase in safety is achieved.
