Abstract

A forceps includes an end effector assembly having first and second jaw members configured to grasp tissue therebetween and conduct energy through tissue grasped therebetween to treat tissue. An insulative tubular member is movable relative to the end effector assembly between a retracted position, wherein the insulative tubular member is positioned proximally of the end effector assembly, and an extended position, wherein the insulative tubular member is disposed about the end effector assembly. A monopolar member is selectively deployable relative to the end effector assembly from a first position to a second position, wherein, in the second position, a portion of the monopolar member extends distally from the end effector assembly and the insulative tubular member for applying energy to tissue to treat tissue.
