Apparatus for Performing an Electrosurgical Procedure
First Claim
1. An endoscopic forceps, comprising:
- a housing having a shaft that extends therefrom and defines a longitudinal axis therethrough;
an end effector assembly operatively connected to a distal end of the shaft and including a pair of first and second jaw members, the first and second jaw members pivotably coupled to one another and movable relative to one another from a first configuration wherein the jaw members are in spaced relation relative to one another, to a second configuration wherein the jaw members cooperate to grasp tissue therebetween; and
a magnetic actuation mechanism operably associated with at least one of the first and second jaw members and configured to generate opposing magnetic fields therebetween to actuate the jaw member between the first and second configurations.

Abstract
An endoscopic forceps is provided and includes a housing having a shaft that extends therefrom. An end effector assembly is operatively connected to a distal end of the shaft and includes a pair of first and second jaw members that are pivotably coupled to one another and movable relative to one another. The first and second jaw members are disposed in a first configuration, wherein the first and second jaw members are disposed in spaced relation relative to one another, to a second configuration, wherein the first and second jaw members cooperate to grasp tissue therebetween. A magnetic actuation mechanism is operably coupled to one or both of the first and second jaw members and configured to generate opposing magnetic fields on each of the first jaw and second jaw members to actuate the first and second jaw members between the first and second configurations.

14. An endoscopic forceps, comprising:
-
a housing having a shaft that extends therefrom and defines a longitudinal axis therethrough; an end effector assembly operatively connected to a distal end of the shaft and including a pair of first and second jaw members, the first and second jaw members pivotably coupled to one another and movable relative to one another from a first configuration, wherein the first and second jaw members are disposed in spaced relation relative to one another, to a second configuration, wherein the first and second jaw members cooperate to grasp tissue therebetween; and a magnetic actuation mechanism operably coupled to each of the first and second jaw members and configured to generate a magnetic field at each of the first jaw and second jaw members, the magnetic actuation mechanism including at least two magnets, wherein each of the at least two magnets operable couple to a respective first and second jaw member, wherein when the magnetic field at each of the first and second jaw members is the same polarity, the first and second jaw members are caused to move to the first configuration and when the magnetic field at the first and second jaw members is a different polarity, the first and second jaw members are cause to move to the second configuration.
