Tissue Sealer and End Effector Assembly and Method of Manufacturing Same
First Claim
1. A bipolar forceps for sealing tissue, comprising:
- at least one shaft having an end effector assembly disposed at a distal end thereof, the end effector assembly including a pair of first and second opposing jaw members movable relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members cooperate to grasp tissue therebetween; and
at least the first jaw member including proximal and distal ends that define a cavity along a length of the first jaw member;
an insulative member disposed within the cavity, the insulative member including an electrically conductive sealing surface mounted thereto disposed in substantial opposition to a second electrically conductive sealing surface disposed on the second jaw member; and
wherein at least the proximal end of the first jaw member extends a fixed distance toward the second jaw member such that the proximal end and the second jaw member form a gap between electrically conductive surfaces when the jaw members are in the second position.

Abstract
A bipolar forceps for sealing tissue includes at least one shaft having an end effector assembly disposed at a distal end thereof. The end effector assembly includes a pair of first and second opposing jaw members movable relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members cooperate to grasp tissue therebetween. At least the first jaw member includes proximal and distal ends which define a cavity along a length thereof which houses an insulative member therein. The insulative member includes an electrically conductive sealing surface mounted thereto which resides in substantial opposition with a second electrically conductive sealing surface disposed on the second jaw member. One end of the first jaw member which defines the cavity extends a fixed distance toward the second jaw member to form a gap between electrically conductive surfaces when the jaw members are closed to grasp tissue.
