摘要： An electrosurgical forceps includes 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 actuates a drive assembly to move the jaw members relative to one another and at least one of the jaw members 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 boot includes a woven mesh-like base material that is covered with a layer of flexible silicone configured to reduce stray currents emanating from the jaw members and the pivot during electrical activation of the forceps.

摘要： An electrosurgical forceps includes a shaft having a pair of jaw members at a distal end thereof, the jaw members 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 includes at least one mechanical interface and at least one jaw member is 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. A flexible insulating boot is disposed on at least a portion of an exterior surface of at least one jaw member and about the pivot, the flexible boot including a first longitudinal portion made from a high durometer material and a second longitudinal portion made from a low durometer material. The high durometer material may be configured to operably retain the flexible insulating boot atop both a proximal end of the jaw members and a distal end of the flexible insulating boot.
