Patent number: 11950873Abstract: A medical instrument includes cable pairs respectively wound around input spindles and connected to actuate degrees of freedom of an instrument shaft structure. The cables may connect so that rotating the input spindles actuates corresponding degrees of freedom. First pulleys in the instrument may receive first cables from the input spindles and redirect the first cables toward the instrument shaft, and second pulleys may receive second cables from the input spindles and redirect the second cables toward the instrument shaft. In one configuration, the first and second pulleys are respectively mounted at first and second levels, and the second pulleys redirect the second cables through the first level. Additionally or alternatively, one level of cables may cross while the other level of cables does not.Type: GrantFiled: November 18, 2021Date of Patent: April 9, 2024Assignee: Intuitive Surgical Operations, Inc.Inventors: Bram Gilbert Antoon Lambrecht, S.

Patent number: 11890070Abstract: A medical instrument includes a backend and a pair of release elements. The backend includes a docking feature shaped to engage a docking structure such as a docking port of a surgical robot or a sterile adaptor for a surgical robot. Each release element is coupled to the backend and may include an activation feature on one side of the backend and a push tab extending from either an opposite side or the same side of the backend. Movement of the activation features moves the push tabs from being aligned with the docking feature to pushing on the docking structure, permitting the medical instrument to be disengaged from the docking structure. Optionally, a coupling of the release elements limits a movement of the activation features.Type: GrantFiled: March 29, 2017Date of Patent: February 6, 2024Assignee: Intuitive Surgical Operations, Inc.Inventors: Bram Gilbert Antoon Lambrecht, Robert E.

Patent number: 11344378Abstract: A method for providing a visual expiration indication for a surgical instrument includes holding an indicator body in a first position with a detent mechanism to provide a visual in-service indication for the surgical instrument. The indicator body is engaged with a motor and the indicator body is rotated with the motor from the first position to a second position that provides a visual expired indication. The indicator body is prevented from rotating from the second position to the first position with the detent mechanism. The detent mechanism may hold the indicator body in one of only two positions. The visual indications may be displayed through an aperture fixed to the base of the surgical instrument. The indicator body may be elastically deformed when the indicator body is rotated from the first position to the second position. The motor may be rotated to gain momentum before rotating the indicator body.Type: GrantFiled: November 11, 2019Date of Patent: May 31, 2022Assignee: Intuitive Surgical Operations, Inc.Inventors: Donald Alden, Bram Gilbert Antoon Lambrecht
