  • Publication number: 20210315648
    Abstract: An actuation mechanism for a medical instrument includes a pinion and a face gear that move a push-pull element. The pinion has a mounting that permits rotation of the pinion by an external control system such as a robot. The face gear meshes with the pinion. The push-pull element may have a proximal end coupled to the face gear and a distal end coupled to a tool at a distal end of an instrument shaft. A manipulator coupled for manual rotation of the actuation mechanism may include a slip clutch to prevent manual application of excessive force to the actuation mechanism.

  • Publication number: 20210251719
    Abstract: A medical instrument includes an instrument shaft with exit holes near a distal end of the shaft, a tool coupled to the distal end of the shaft, and a backend. The backend may include a mechanism that manipulates a drive element that extends through the shaft and couples to the tool, a fluid inlet, and a fluid channel assembly providing fluid communication between the fluid inlet and the proximal end of the shaft. Cleaning fluid is directed into the fluid inlet, through the fluid channel assembly, and into the shaft. A chassis or other structural piece of the backend may form part of the fluid channel assembly.

  • Publication number: 20210220062
    Abstract: A medical instrument includes a roll mechanism that rotates an instrument shaft. The roll mechanism may include a first gear coupled to the instrument shaft and meshed with a second gear. One of gears may be a spur gear while the other gear may be a beveloid gear. Further, the spur gear and the beveloid gear may be in a gear train containing a compressible gear, e.g., a gear with an inner center piece, an outer ring, and a flexible interconnecting structure between the inner center piece and the outer ring. With a compressible gear, an interference fit of in the gear train may be within manufacturing variations of the gear train, and the compressible gear may deflect radially away from the interference fit.

  • Patent number: 11013566
    Abstract: A force transmission mechanism for a surgical instrument includes a worm drive, a lever arm, and an actuation element. The lever arm may include a follower member at a first end of the lever arm. The follower member engages the worm drive and is configured to be driven by the worm drive. The actuation element is connected the lever arm. The actuation element is configured to transmit force to actuate an end effector of the surgical instrument. Rotational movement of the worm drive imparts translational movement to the actuation element via the lever arm.

  • Publication number: 20210015566
    Abstract: A system, e.g., a computer-aided medical system, includes a first link, a second link, a joint, and a dual brake assembly. The first link has a first end portion and a second end portion. The second link has a first end portion and a second end portion. The joint is connected to the second end portion of the first link and to the first end portion of the second link. The dual brake assembly is coupled to the first link and to the second link. The dual brake assembly includes a first brake and a second brake. Braking provided by the dual brake assembly reduces relative motion between the first and second links.

  • Publication number: 20200179004
    Abstract: In accordance with aspects of the present invention, a door mechanism is provided. A door mechanism according to some embodiments of the present invention includes a door that includes a sealing part, an arm connected to the sealing part, and a pivot part connected to the arm, the door rotating around a pivot axis at the pivot part; and a lever, the lever engaging the door at the pivot part such that the lever opens the door when engaged but is not affected when the door is opened without the lever.

  • Publication number: 20200078107
    Abstract: 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.

  • Publication number: 20200078049
    Abstract: A cannula seal is presented. The cannula seal includes a cross-slit seal that can include a side wall that includes folded sidewalls; slits that are formed by the folded sidewalls when the cross-slit seal is in a closed position; and a concave end surface at the slits. The cross-slit seal can include energizing ribs formed to close the seal. The instrument guide includes a pyramidal shaped seal that seals against doors when no instrument is inserted and seals against an instrument when the instrument is inserted.

  • Patent number: 10470829
    Abstract: An indicator mechanism for a surgical instrument includes an aperture fixed to a base. An indicator body is rotatably supported by the base. The indicator body includes features for engaging a motor that rotates the indicator body. A visual indicator, visible through the aperture, is coupled to the indicator body. A detent mechanism holds the indicator body in one of two positions. A first of the two positions provides a visual indication that the surgical instrument is in service and a second of the two positions provides a visual indication that the surgical instrument is expired. A controller may track use events for a surgical instrument to determine expiration. Use events may include operations and conditions in addition to those that occur in the surgical instrument. When the use events tracked by the controller indicate expiration, the controller may rotate a motor to set the visual indication to expired.

  • Publication number: 20190307522
    Abstract: 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.
