Insulating mechanically-interfaced boot and jaws for electrosurgical forceps
First Claim
1. An electrosurgical forceps, comprising:
- a shaft having a pair of jaw members at a distal end thereof, the jaw members being movable about a pivot 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 are closer to one another for grasping tissue;
a movable handle that actuates a drive assembly to move the jaw members relative to one another;
at least one of the jaw members being adapted to connect to a source of electrical energy such that the at least one jaw member is capable of conducting energy to tissue held between the pair of jaw members;
a flexible insulating boot disposed on at least a portion of an exterior surface of at least one jaw member and disposed circumferentially around at least a portion of the pivot, the flexible insulating boot defining an exterior surface and an inner peripheral surface; and
at least one retention element configured to directly couple to both a proximal end of the jaw members and a distal end of the shaft,wherein the at least one retention element includes a pair of hook-like mechanical interfaces that engage the jaw members at the proximal end thereof and that engage the shaft at the distal end thereof.

Abstract
An electrosurgical forceps includes a shaft having a pair of jaw members at a distal end movable about a pivot from a first position disposed in spaced relation relative to one another to a second position wherein the jaw members are closer to one another for grasping tissue. A movable handle actuates a drive assembly to move the jaw members relative to one another. One (or both) of the jaw members is adapted to connect to a source of electrosurgical energy such that the jaw members are capable of conducting electrical energy to tissue held therebetween. A flexible insulating boot is disposed on an exterior surface of one or both jaw members and about the pivot and at least one retention element is configured to operably couple to both a proximal end of the jaw members and a distal end of the flexible insulating boot.
