Abstract:
1. An electrosurgical system, comprising: an electrosurgical generator for generating electrosurgical energy; a first shaft having a jaw member attached to a distal end thereof, a second shaft having a jaw member attached to a distal end thereof, the first and second jaw members each including a sealing surface disposed thereon which reside in opposing relation relative to one another, the jaw members being movable from a first position wherein the sealing surfaces are disposed in spaced apart relation relative to one another to at least one second position wherein the sealing surfaces grasp tissue therebetween; a connector adapted to electrically couple the jaw members to a source of electrosurgical energy such that the sealing surfaces are capable of conducting electrosurgical energy through tissue held therebetween; a ratchet operatively associated with at least one of the shafts, the ratchet being selectively positionable to maintain to a closure pressure in the range of about 7 kg/cm regulating means being configured to monitor the phase angle between the output voltage and the current emanating from the electrosurgical generator and terminate the electrosurgical energy once the phase angle reaches a predetermined angle.
