Endoscopic electrosurgical jaws with offset knife
First Claim
1. A forceps, comprising:
- an end effector assembly, including;
first and second jaw members, each jaw member including a proximal flange having an inwardly-facing surface, the proximal flanges coupled to one another for moving the jaw members relative to one another between a first position and a second position for grasping tissue therebetween, the inwardly-facing surfaces of the proximal flanges disposed in abutting relation relative to one another;
a knife configured to move along a knife path defined along an outwardly-facing surface of one of the proximal flanges, the knife movable between a refracted position and an extended position, wherein the knife extends between the jaw members to cut tissue grasped therebetween; and
a knife guide disposed on the outwardly-facing surface of at least one of the proximal flanges, the knife guide including a blade stop pivotably coupled thereto and biased to obstruct the knife path when the first and second jaw members are disposed in a first, open configuration to prevent distal translation of knife blade.

Abstract
A forceps includes an end effector assembly having first and second jaw members. Each jaw member includes a proximal flange having an inwardly-facing surface. The proximal flanges are coupled to one another for moving the jaw members relative to one another between a first position and a second position for grasping tissue therebetween. The inwardly-facing surfaces of the proximal flanges are disposed in abutting relation relative to one another. A knife is configured to move along a knife path defined along an outwardly-facing surface of one of the proximal flanges. The knife is movable between a retracted position and an extended position, wherein the knife extends between the jaw members to cut tissue grasped therebetween.

9. A forceps, comprising:
-
an end effector assembly, including; first and second jaw members, at least one of the jaw members defining a knife channel extending therethrough, each jaw member including a proximal flange having an inwardly-facing surface, the proximal flanges coupled to one another for moving the jaw members relative to one another between a first position and a second position for grasping tissue therebetween, the inwardly-facing surfaces of the proximal flanges disposed in abutting relation relative to one another; a knife configured to move along a knife path defined along an outwardly-facing surface of one of the proximal flanges, the knife movable between a retracted position and an extended position, wherein the knife extends through the knife channel and between the jaw members to cut tissue grasped therebetween; and a knife guide disposed on the outwardly-facing surface of at least one of the proximal flanges, the knife guide including a blade stop pivotably coupled thereto and biased to obstruct the knife path when the first and second jaw members are disposed in a first, open configuration to prevent distal translation of knife blade. - View Dependent Claims (10, 11, 12, 13, 14)
