Insulating boot for electrosurgical forceps with thermoplastic clevis
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 the shaft to move the jaw members relative to one another;
at least one of the jaw members 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 therebetween; and
an insulating boot disposed on at least a portion of an exterior surface of at least one jaw member, about the pivot and at a distal end of the shaft, the insulating boot including an overmolded thermoplastic clevis disposed on an inner periphery thereof, the overmolded thermoplastic clevis being configured to enhance the mechanical engagement of the insulating boot with the at least one jaw member and the distal end of the shaft, the insulating boot further including an outer thermoplastic portion that is configured to further enhance the rigidity of the insulating boot.

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 the shaft to move the jaw members relative to one another. One or both jaw members are capable of conducting electrical energy to tissue held therebetween. An insulating boot is disposed on at least a portion of an exterior surface of one or both jaw members about the pivot and at a distal end of the shaft. The insulating boot includes an overmolded thermoplastic clevis disposed on an inner periphery thereof configured to enhance mechanical engagement of the insulating boot with the one or both jaw members and the distal end of the shaft.
