1. An electrosurgical system comprising:
an electrosurgical generator arranged to output electrosurgical energy; and
a bipolar electrosurgical tool removably coupled to the electrosurgical generator, the tool comprising:
a stationary handle;
an actuation handle movably coupled to the stationary handle;
a blade trigger movably coupled to the stationary handle;
a jaw assembly comprising an upper jaw having an inner surface, an outer surface, and an electrode disposed on the inner surface of the upper jaw and a lower jaw having an inner surface, an outer surface, an electrode disposed on the inner surface of the lower jaw, a lower spacer disposed adjacent to the electrode, a blade channel disposed adjacent to the lower spacer, and a cutting blade disposed within the blade channel, the upper and lower jaws actuatable, by movement of the actuation handle, from an open configuration in which the inner surface of the upper jaw is spaced apart from the inner surface of the lower jaw to a closed configuration in which the inner surface of the upper jaw is proximate the inner surface of the lower jaw, arranged to contact tissue and apply the electrosurgical energy to the tissue from the electrosurgical generator; and
a rotatable elongate shaft extending distally from the stationary handle and rotatable relative to the stationary handle, the rotatable elongate shaft having a proximal end and a distal end defining a central longitudinal axis therebetween, the jaw assembly pivotably connected and positioned at the distal end of the rotatable elongate shaft and the rotatable elongate shaft comprises a blade actuation shaft formed of two polymer mating shaft sections including a proximal shaft portion and a distal shaft portion, the proximal shaft portion and the distal shaft portion connected by interlocks including projections on at least one of the proximal shaft portion or the distal shaft portion with corresponding slots on the at least one of the proximal shaft portion or the distal shaft portion, the cutting blade being connected to the distal shaft portion of the blade actuation shaft and the blade trigger being connected to the proximal shaft portion such that movement of the blade trigger moves the cutting blade longitudinally along the blade channel.
