Bipolar electrosurgical forceps with non-conductive stop members
First Claim
1. A bipolar forceps, comprising:
- at least one elongated shaft having opposing jaw members at a distal end thereof, the jaw members being 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;
a source of electrical energy connected to each jaw member such that the jaw members are capable of conducting energy through tissue held therebetween; and
at least two non-conductive and spaced-apart stop members disposed on an inner facing surface of at least one of the jaw members which control the distance between the jaw members when tissue is held therebetween.

Abstract
A bipolar forceps for clamping and sealing tissue includes at least one elongated shaft having opposing jaw members at a distal end thereof which are 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. The forceps is also connected to a source of electrical energy which, in turn, connects to each jaw member to the source of electrosurgical energy such that the jaw members are capable of conducting energy through tissue held therebetween. At least two non-conductive and spaced-apart stop members are disposed on an inner facing surface of the jaw members to control the gap distance between the jaw member(s) when tissue is held therebetween.
