Abstract
A surgical tool that includes a drive housing, an elongate shaft that extends from the drive housing, and an end effector arranged at a distal end of the elongate shaft and having a jaw and a jaw holder that secures the jaw. A wrist couples the end effector to the elongate shaft and includes a distal clevis having an axle that rotatably mounts the jaw holder to the distal clevis. An electrical conductor extends from the drive housing and supplies electrical energy to the jaw via a supply conductor. At least one of the jaw holder and the axle is made of a non-conductive material that insulates the distal clevis from the electrical energy provided to the jaw.
