Patent number: 11357566Abstract: 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.Type: GrantFiled: December 27, 2017Date of Patent: June 14, 2022Assignee: Intuitive Surgical Operations, Inc.Inventors: Scott E. Manzo, William A. Burbank, Richard D. Gresham

Patent number: 11000331Abstract: 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.Type: GrantFiled: July 13, 2018Date of Patent: May 11, 2021Assignee: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: Justin Krom, Kenneth L.

Patent number: 9693771Abstract: A staple is provided having a backspan and a first and second legs extending distally from the backspan. Each of the first and second legs includes a bend dividing each leg into a traversing leg portion and a substantially linear clenching leg portion. A staple plate is positionable over the first and second legs between the backspan and the first and second clenching leg portions. An anvil assembly has first and second movable members which move toward to one another to engage outer surfaces of the first and second clenching leg portions. There is further disclosed a method of forming the staple through tissue.Type: GrantFiled: October 9, 2013Date of Patent: July 4, 2017Assignee: Covidien LPInventors: Russell Heinrich, Robert J.
