Abstract: A forceps includes an end effector assembly having first and second jaw members movable between a spaced-apart position and an approximated position for grasping tissue therebetween. Each jaw member includes an electrically-conductive tissue-contacting surface adapted to connect to a source of energy to treat tissue grasped between the jaw members. The first jaw member includes a cutting electrode adapted to connect to the source of energy to cut tissue grasped between the jaw members, while the second jaw member including a first insulative member positioned to oppose the cutting electrode. The first insulative member is configured to guide the cutting electrode into alignment with the first insulative member upon approximation of the jaw members to thereby align the jaw members relative to one another upon approximation of the jaw members.

Abstract: An end effector of a forceps includes first and second jaw members movable between spaced-apart and approximated positions for grasping tissue. Each jaw member includes a tissue sealing plate that is selectively energizable. The tissue sealing plates are configured to conduct energy therebetween and though tissue to seal tissue. A knife includes a distal surface and an upper surface. The knife is selectively translatable between a retracted position and an extended position wherein the knife extends between the jaw members. The distal surface is configured for dynamic tissue cutting upon translation of the knife from the retracted to the extended position. The upper surface is configured for static tissue cutting with the knife in the extended position. The knife is selectively energizable and is configured to conduct energy between the knife and one or both of the tissue sealing plates and through tissue to electrically cut tissue.
