Surgical forceps
First Claim
1. A forceps, comprising:
- an end effector assembly, including;
first and second jaw members, each of the jaw members including a distal body portion and a proximal flange, each proximal flange defining a bifurcated configuration having first and second spaced-apart flange components, the proximal flanges of the first and second jaw members disposed in an offset configuration wherein the first or second flange component of the first jaw member is disposed between the first and second flange components of the second jaw member and wherein the first or second flange component of the second jaw member is disposed between the first and second flange components of the second jaw member, the first flange component of the first jaw member coupled to the second flange component of the second jaw member via a first pivotable engagement and the first flange component of the second jaw member coupled to the second flange component of the first jaw member via a second, different pivotable engagement, wherein the first pivotable engagement is a first protrusion-aperture engagement and wherein the second pivotable engagement is a second, different protrusion-aperture engagement, the proximal flanges of the first and second jaw members cooperating to define a channel extending longitudinally therethrough between the first and second pivotable engagements; and
a knife configured for reciprocation through the channel between the first and second pivotable engagements to permit reciprocation of the knife at least partially between the distal body portions of the first and second jaw members.

Abstract
A forceps includes an end effector assembly having first and second jaw members. Each of the jaw members includes a proximal flange extending therefrom. Each of the proximal flanges defines a bifurcated configuration having first and second spaced-apart flange components. The first flange component of the first jaw member is configured to pivotably engage the second flange component of the second jaw member via a first protrusion-aperture coupling. The first flange component of the second jaw member is configured to pivotably engage the second flange component of the first jaw member via a second protrusion-aperture coupling different from the first protrusion-aperture coupling. One or both of the jaw members is pivotable relative to the other about the first and second protrusion-aperture couplings between a spaced-apart position and an approximated position for grasping tissue therebetween.

8. A forceps, comprising:
-
a shaft defining a longitudinally-extending lumen therethrough and first and second opposed, transverse shaft apertures defined within an outer periphery thereof towards a distal end of the shaft; an end effector assembly disposed at a distal end of the shaft, the end effector assembly including first and second jaw members, each of the jaw members including a distal body portion and a proximal flange, each proximal flange defining a bifurcated configuration having first and second spaced-apart flange components, the first flange component of the first jaw member, the second flange component of the second jaw member, and the first transverse shaft aperture of the shaft coupled to one another via a first pivotable engagement, the first flange component of the second jaw member, the second flange component of the first jaw member, and the second transverse shaft aperture of the shaft coupled to one another via a second, different pivotable engagement, wherein the first pivotable engagement is a first protrusion-aperture engagement and wherein the second pivotable engagement is a second, different protrusion-aperture engagement, the proximal flanges of the first and second haw members cooperating to define a channel extending longitudinally therethrough between the first and second pivotable engagements, the channel disposed in communication with the lumen of the shaft; and a knife disposed within the lumen of the shaft and configured for reciprocation through the channel between the first and second pivotable engagements to permit reciprocation of the knife at least partially between the distal body portions of the first and second jaw members. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
