Surgical forceps
First Claim
1. A surgical instrument, comprising:
- a housing;
a shaft extending distally from the housing;
an end effector assembly disposed at a distal end of the shaft; and
a monopolar assembly including a tubular member and a monopolar electrode, the tubular member at least partially formed from an insulative material and slidably disposed about the shaft, the monopolar electrode engaged to the tubular member, disposed at least partially within the tubular member, and extending distally from the tubular member,wherein the monopolar assembly is deployable from a retracted position, wherein the tubular member is positioned proximally of the end effector assembly and a distal end of the monopolar electrode is positioned towards a proximal end of the end effector assembly, and an extended position, wherein the tubular member surrounds the end effector assembly and the distal end of the monopolar electrode extends distally from the end effector assembly.

Abstract
A forceps includes an end effector assembly including first and second jaw members. One or both of the jaw members is movable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. One or both of the jaw members is configured to conduct energy between the jaw members and 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 configured to apply energy to tissue to treat tissue when the insulative tubular member is disposed in the extended position.

12. A surgical instrument, comprising:
-
a housing; a shaft extending distally from the housing; an end effector assembly disposed at a distal end of the shaft, the end effector assembly including first and second jaw members pivotably coupled to one another, at least one of the first or second jaw members pivotable relative to the other between a spaced-apart position and an approximated position, each of the first and second jaw members including an electrically-conductive surface adapted to connect to a source of bipolar energy; and a monopolar assembly including a tubular member and a monopolar electrode, the tubular member at least partially formed from an insulative material and slidably disposed about the shaft, the monopolar electrode engaged to the tubular member, disposed at least partially within the tubular member, and extending distally from the tubular member, the monopolar electrode adapted to connect to a source of monopolar energy, wherein the monopolar assembly is deployable from a retracted position, wherein the tubular member is positioned proximally of the end effector assembly and a distal end of the monopolar electrode is positioned towards a proximal end of the end effector assembly, and an extended position, wherein the tubular member surrounds the end effector assembly and the distal end of the monopolar electrode extends distally from the end effector assembly.
