Abstract

An end effector for an electrosurgical forceps is provided. The end effector includes a first jaw member having proximal and distal ends and a second jaw member having proximal and distal ends. The distal end of the first jaw member includes a recess defined therein. The distal end of the second jaw member includes a first prong configured for receipt within the recess defined in the first jaw member. Wherein engagement of the first prong of the second jaw member within the recess of the first jaw member creates a gap between the first and second jaw members to enable tissue sealing.

Claims

1. An end effector for an electrosurgical forceps, comprising:

a first jaw member having proximal and distal ends, the distal end including a recess defined therein; and

a second jaw member having proximal and distal ends, the distal end including a first prong configured for receipt within the recess defined in the first jaw member, wherein engagement of the first prong of the second jaw member within the recess of the first jaw member creates a gap between the first and second jaw members and is configured to prevent splaying of the first and second jaw members relative to one another.

2. The end effector of claim 1, wherein the gap is about 0.001 inches to about 0.006 inches.

3. The end effector of claim 1, wherein the first jaw member includes a first electrode and the second jaw member includes a second electrode, the first electrode positioned proximal to the recess and the second electrode positioned proximal to the first prong.

4. The end effector of claim 3, wherein the first and second electrodes are flush relative to respective first and second tissue contacting surface of respective first and second jaw members.

5. The apparatus of claim 1, wherein the recess in the first jaw member is defined by a pair of prongs extending from a distal end thereof.

6. The apparatus of claim 5, wherein the first prong in the second jaw member includes a pair of shoulder portions configured to engage the pair of prongs formed in the first jaw member.

7. A system for the treating of tissue, the system comprising:

an apparatus having first and second jaw members configured to selectively receive tissue therebetween,

wherein the first jaw member includes proximal and distal ends, the distal end defining a recess therein, and

wherein the second jaw member includes proximal and distal ends, the proximal end of the second jaw member pivotably coupled to the proximal end of the first jaw member, wherein the distal end of the second jaw member is in a spaced apart relationship with the first jaw member when in a first position, and the distal end of the second jaw member is received within the recess formed in the first jaw member when in a second position, forming a gap between the first and second jaw members; and

a source of electrosurgical energy operably connected to at least one of the jaw members to deliver electrosurgical energy to the tissue.
