Monopolar pencil with integrated bipolar/ligasure tweezers
First Claim
1. An electrosurgical pencil, comprising:
- an elongated housing having an open distal end, the elongated housing including an actuator operably associated therewith;
first and second jaw members extending distally through the open distal end of the elongated housing and transitionable between a closed position and an open position upon actuation of an actuator, at least one of the jaw members configured to treat tissue with monopolar energy and both jaw members configured to treat tissue with bipolar energy;
at least one switch operably coupled to a controller disposed in the housing, the at least one switch configured to activate the first and second jaw members to treat tissue with monopolar and bipolar energy;
a sensor operably coupled to the pencil and configured to sense tissue disposed between the jaw members, the sensor providing a signal to the controller to disable bipolar activation in the absence of tissue sensed between the jaw members; and
an intensity controller that controls the amount of energy delivered to tissue when treating tissue with monopolar energy, the intensity controller including a pressure sensitive activator that adjusts the amount of electrosurgical energy based on the amount of pressure applied to the intensity controller.

Abstract
An electrosurgical pencil with integrated ligasure tweezers includes—an elongated housing having an open distal end and an actuator operatively associated therewith. First and second jaw members extend distally through the open distal end of the elongated housing and are transitionable between a closed position and an open position upon actuation of an actuator. One or both of the jaw members is configured to treat tissue with monopolar energy and both jaw members are configured to treat tissue with bipolar energy. One or more switches is operably coupled to a controller disposed in the housing and configured to activate the first and second jaw members to treat tissue with monopolar and bipolar energy.

10. An electrosurgical pencil, comprising:
-
an elongated housing having first and second jaw members extending through a distal end thereof, the first and second jaw members transitionable between a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members are approximated relative to one another, at least one of the jaw members configured to treat tissue with monopolar energy and both jaw members configured to treat tissue with bipolar energy; an actuator operably coupled to the jaw members and actuatable to transition the jaw members between the first and second positions, the actuator operably coupled to a controller that senses the disposition of the jaw members; a switch disposed in the housing in operative communication with the controller, the switch configured to activate the jaw members with bipolar energy if the jaw members are disposed in the first position and to activate at least one of jaw members with monopolar energy if the jaw members are disposed in the second position; an intensity controller that controls the amount of energy delivered to tissue when treating tissue with monopolar energy, the intensity controller including a pressure sensitive activator that adjusts the amount of electrosurgical energy based on the amount of pressure applied to the intensity controller. - View Dependent Claims (11, 12, 13, 14, 15)
