摘要：
abstract a surgical tool can comprise an end effector, a shaft assembly, a rotatable drive shaft, a first electrical contact and a second electrical contact. the end effector comprises first and second jaw members that are pivotable relative to one another from an open position to a closed position and an electrode positioned on the first jaw member. the shaft assembly extends proximally from the end effector, is at least partially hollow, and defines an inner wall. the rotatable drive shaft extends proximally within the shaft assembly. the first electrical contact is coupled to the inner wall of the shaft assembly and positioned around at least a portion of the drive shaft. the second electrical contact is coupled to and rotatable with the drive shaft. the second electrical contact is positioned to be electrically connected to the first electrical contact as the drive shaft rotates. patent abstract: "electrode connections for rotary-driven surgical tools". A surgical tool is presented which may comprise an end actuator, a stem assembly, a rotary drive rod, a first electrical contact and a second electrical contact. the end actuator comprises a first and second jaw members that are pivotal to each other from an open to a closed position and an electrode positioned on the first jaw member. the stem assembly extends proximally from the end actuator, is at least partially hollow, and defines an inner wall. the swivel drive rod extends proximally within the rod assembly. The first electrical contact is coupled to the inner wall of the rod assembly, and positioned around at least a portion of the drive rod. The second electrical contact is coupled to and in rotational relationship with the drive rod. The second electrical contact is positioned to be electrically connected to the first electrical contact as the drive rod rotates.abstract a surgical tool can comprise an end effector, a shaft assembly, a rotatable drive shaft, a first electrical contact and a second electri
