Tapered Insulating Boot 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 including at least one mechanical interface and at least one jaw member 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 therebetween; and
a flexible insulating boot disposed on at least a portion of an exterior surface of at least one jaw member and about the pivot, the flexible insulating boot including proximal and distal portions, the distal portion including a taper with a smaller annular diameter than the proximal portion of the flexible insulating boot.

Abstract
An electrosurgical forceps includes a shaft having a pair of jaw members at a distal end thereof that are 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 is included that actuates a drive assembly to move the jaw members relative to one another. One or both of the jaw members includes at least one mechanical interface and is adapted to connect to a source of electrical energy such that the jaw members are capable of conducting energy to tissue held therebetween. A flexible insulating boot is disposed on at least a portion of an exterior surface of one or both jaw members and about the pivot. The flexible insulating boot includes both proximal and distal portions, the distal portion including a taper with a smaller annular diameter than the proximal portion of the flexible insulating boot.
