First Claim
1. An endoscopic forceps, comprising:
- a shaft having a proximal end and a distal end;
a housing attached to the proximal end of the shaft;
a pair of jaw members disposed at the distal end of the shaft, each jaw member adapted to connect to a source of electrical energy such that the jaw members are capable of conducting energy for treating tissue;
a drive assembly disposed in the housing, the drive assembly operable to move at least one of the pair of jaw members relative to the other jaw member 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 manipulating tissue;
first and second handles operatively connected to the drive assembly, the handles movable relative to the housing to actuate the drive assembly to move the jaw members;
a first toggle link which operatively connects the first handle to the drive assembly; and
a second toggle link which operatively connects the second handle to the drive assembly, wherein each of the first and second toggle links is an integral component including;
a link body defining a first end and a second end;
a first anchoring element disposed at the first end of the link body and configured to pivotably engage the handle, the first anchoring element including a pair of tangs and a slot extending therebetween, the slot oriented in a direction of an applied load for moving the jaw members to the second position such that the slot offsets a portion of the applied load; and
a second anchoring element disposed at the second end of the link body and configured to pivotably engage the drive assembly, the second anchoring element including a pair of tangs and a slot extending therebetween, the slot oriented in a direction of an applied load for moving the jaw members to the second position such that the slot offsets a portion of the applied load.

Abstract
An endoscopic forceps includes a housing having a shaft attached thereto, the shaft including a pair of jaw members disposed at a distal end thereof. The forceps also includes a drive assembly disposed in the housing which moves the jaw members relative to one another 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 manipulating tissue. A pair of handles is operatively connected to the drive assembly and the handles are movable relative to the housing to actuate the drive assembly to move the jaw members. Each of the jaw members is adapted to connect to a source of electrical energy such that the jaw members are capable of conducting energy for treating tissue. The forceps also includes a first switch disposed on the housing which is activatable to selectively deliver energy of a first electrical potential to at least one jaw member for treating tissue in a monopolar fashion. A second switch is disposed on the housing and is activatable to selectively deliver energy of a first electrical potential to one jaw member and selectively deliver energy of a second electrical potential to the other jaw member for treating tissue in a bipolar fashion.
