摘要:
Various safe switching mechanisms are provided for use with electrosurgical instruments which prevent arcing between the high-energy contacts as the high-energy source is activated. The switching mechanisms generally include a pair of high-energy contacts and a pair of activation contacts. An actuator is provided which initially engages the high-energy contacts in advance of engagement of the activation contacts to prevent arcing and subsequently disengages the activation contacts in advance of the high-energy contacts as the energy source is deactivated. A method of switching power to an electrosurgical instrument while avoiding damage to high-energy contacts is also disclosed.
