    摘要： An endoscopic instrument includes a housing having shaft extending therefrom that defines a longitudinal axis therethrough. The shaft includes an articulating section disposed thereon. The articulating section has a central annulus extending therealong and first and second pluralities of bores. The first plurality of bores configured to receive corresponding tendons therethrough and the second plurality of bores configured to receive corresponding conductive leads therethrough. An end effector assembly operatively connected to a distal end of the shaft including a pair of first and second jaw members. The corresponding conductive leads transition from a first state for enabling articulation of the shaft about the articulating section, to a second state for disabling articulation of the shaft about the articulating section.

    摘要： A surgical instrument includes a handle, an elongated shaft and an end effector extending distally from the shaft. A tensile member is preloaded with a tensile force and extends at least partially through the shaft. A preload mechanism for adjusting the tensile force includes first and second guides in contact with the tensile member to restrain the tensile member at respective first and second lateral distances from a longitudinal axis. A third guide is disposed longitudinally between the first and second guides and is in contact with the tensile member to restrain the tensile member at a third lateral distance from the longitudinal axis. The third guide is movable to vary the third lateral distance and a corresponding length of the tensile member disposed longitudinally between the first and second guides to thereby vary the tensile force.

    摘要： A forceps includes an end effector assembly having first and second jaw members. One (or both) of the first and second jaw members is moveable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. One (or both) of the jaw members includes a longitudinally-extending blade channel defined therein. An electrical cutting insert is releasably engageable within the blade channel of the jaw member such that the jaw member is transitionable between a mechanical cutting mode, wherein the electrical cutting insert is disengaged from the jaw member to permit reciprocation of a knife blade through the blade channel for mechanically cutting tissue grasped between the jaw members, and an electrical cutting mode, wherein the electrical cutting insert is engaged within the blade channel of the jaw member for electrically cutting tissue grasped between the jaw members.
