Abstract: An electrically energized medical instrument uses one or more drive cables to both actuate mechanical components of a wrist mechanism or an effector and to electrically energize the effector. Electrical isolation can be achieved using an insulating main tube through which drive cables extend from a backend mechanism to the effector, an insulating end cover that leaves only the desired portions of the effector exposed, and one or more seals to prevent electrically conductive liquid from entering the main tube. Component count and cost may be further reduced using a pair of pulleys that are shared by four drive cables.

Abstract: A cover for an electrosurgical instrument having a wrist structure and an end effector is provided. The cover includes a hollow elongated structure, which includes a tip cover portion and a base cover portion integrally connected to the tip cover portion. The tip cover portion has a distal end with an opening therethrough sized to receive the end effector of the electrosurgical instrument and is composed of a first, electrically insulative material having a flexibility sufficient to allow the end effector to be manipulated while the end effector is received in the opening. The base cover portion is composed of a second material having a higher tear strength than the first material. The tip cover portion and the base cover portion overlap at an overlap region configured to receive the wrist structure of the electrosurgical instrument when the end effector is received in the opening.
