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.

摘要： An electrode sealing assembly is designed for use with an electrosurgical instrument for sealing tissue and includes first and second jaw members each having an insulative housing and being movable from a first position in spaced relation relative to one another to at least one second position for grasping tissue therebetween. Each of the jaw members includes an electrically conductive sealing member disposed within the respective insulative housing. At least one of the insulative housings includes at least one tissue engaging surface configured to extend beyond the electrically conductive sealing member of one of the jaw members. The tissue engaging surface of the insulative housing cooperates with the opposing insulative housing of the opposing jaw member to both pinch and spread tissue when the jaw members are moved to the second position to decrease extraneous energy transmittance to tissue surrounding the jaw members.
