Abstract
A bipolar electrosurgical instrument includes a housing and an elongated shaft. An end effector is coupled to a distal end of the elongated shaft. A handle assembly includes a movable handle movable relative to a fixed handle for effecting movement of the jaw members from a first position to a second position. Each jaw member is configured to connect to a source of electrosurgical energy. A switch is disposed on the fixed handle and configured to be depressed between a first position and at least one subsequent position upon biasing engagement with a switch engaging surface disposed on the movable handle. The first position of the switch causes the relay of information to the user corresponding to a desired pressure on tissue grasped between the jaw members and the at least one subsequent position is configured to activate the source of electrosurgical energy.
