APPARATUS FOR TISSUE CUTTING AND SEALING

摘要

An electrosurgical device for cutting and sealing tissue includes an upper jaw located at a distal end of the electrosurgical device that opposes a lower jaw. The lower jaw is pivotally connected to the upper jaw by a pivot connection. The electrosurgical device further comprises an actuation wire looped through a passage in one of the upper and lower jaws. The actuation wire comprises a first actuation wire section and a second actuation wire section. The first actuation wire section crosses over the second actuation wire section at a cross-over point so that the first and second actuation wire sections exert equal forces on said one of the upper and lower jaws through which the actuation wire is looped.
