Abstract:
An endoscopic electrocautery instrument for performing surgery on tissue of a patient and passing current through the tissue to cause cauterization thereof, the instrument having a proximal end and a distal end and comprising:a proximal actuator;an elongated tube having a proximal end connected to the actuator and a distal end;a push rod extending through the elongated tube and including a proximal end connected to the actuator;first and second end effectors located adjacent the elongated tube distal end and connected to the push rod to provide relative movement of the first and second end effectors upon actuation of the proximal actuator;a first current path passing cautery current from the instrument proximal end to an end effector first portion by a movable conductive rod having a proximal end coupled to a cautery current connector and a distal end slidably contacting a proximal end of the elongated tube; anda second current path insulated from the first current path and passing cautery current from the instrument proximal end to an end effector second portion, the second current path including the push rod.
