Abstract
An RF surgical apparatus and method for operating such an apparatus. The RF surgical apparatus comprises at least two RF generators and at least one neutral electrode output for one neutral electrode. At least two outputs for connecting RF surgical instruments for applying treatment currents to the surgical instruments are provided. Furthermore, a switching device is provided. To enable a simultaneous operation of several RF surgical apparatuses, and not generate any neuromuscular stimulation, a separate generator is provided for each RF surgical instrument and a single neutral electrode is provided for all of the instruments and generators. The switching device is adapted to be arranged in a controlling connection with the RF generators such that the RF generators will never generate, and output to the instruments, any treatment currents at the same time (that is, they output only sequentially).
