Abstract
An APC device to simultaneously operate a plurality of instruments for argon plasma coagulation. In order to enable simultaneous connection and operation of several instruments, the APC device provides several instrument hubs to connect the plurality of instruments and to connect a control device to all instrument hubs. The control device controls the amplitude of a high-frequency voltage and operates the APC device such that, on actuation of at least one actuation means and generation of at least one actuation signal, the high-frequency voltage is interrupted for a defined duration and then the high-frequency voltage is set to the ignition voltage level and, after ignition of the plasma on all of the APC instruments for which the actuation means is actuated, the high-frequency voltage is set to the operational voltage level.
