Publication number: 20250228605Abstract: An instrument may comprise a shaft and an end effector comprising a jaw mechanism coupled to the shaft. The jaw mechanism may comprise a first jaw member and a second jaw member movable relative to one another by pivoting about a pivot axis between an open configuration of the jaw mechanism and a closed configuration of the jaw mechanism. The second jaw member may be rotatable about a roll axis of the second jaw member between at least two orientations, the roll axis of the second jaw member being transverse to the pivot axis. In a first orientation of the at least two orientations, the jaw mechanism is configured to perform a first function. In a second orientation of the at least two orientations, the jaw mechanism is configured to perform a second function differing from the first function.Type: ApplicationFiled: September 9, 2022Publication date: July 17, 2025Applicant: INTUITIVE SURGICAL OPERATIONS, INC.Inventor: Matthew Aaron Wixey

Patent number: 12137903Abstract: Locking assemblies for surgical clamping and cutting instruments include a locking member and a switch. A drive member may be configured to releasably engage a knife and/or a shuttle of the surgical instrument for translating the knife and/or shuttle in a distal direction through a firing stroke. The locking member is movable from a first position permitting distal translation of the drive member through the firing stroke, and a second position inhibiting distal translation of the drive member through the firing stroke. A switch, when proximally positioned, releasably engages the locking member to maintain the locking member in the first position. The switch disengages from the locking member when the switch is moved to a distal position.Type: GrantFiled: August 18, 2022Date of Patent: November 12, 2024Assignee: Intuitive Surgical Operations, Inc.Inventors: Atal C Patel, Matthew Aaron Wixey

Publication number: 20240189054Abstract: A drive assembly of an instrument includes an input drive interface removably engageable with an external actuator device and configured to receive drive actuation force from the external actuator device in a state of engagement with the external actuator device, a drive shaft configured to be driven in rotation, a capstan, and a splined snap-fit connection mechanism between the drive shaft and the capstan. The splined snap-fit connection mechanism includes splined engagement features configured to engage each other so as to prevent relative rotation between the drive shaft and the capstan, and a plurality of snap-fit elements to provide a snap-fit engagement between the drive shaft and the capstan so as to provide resistance to relative axial movement between the drive shaft and the capstan.Type: ApplicationFiled: December 14, 2023Publication date: June 13, 2024Applicant: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: Matthew Aaron Wixey, Nicholas H.

Publication number: 20220015849Abstract: A surgical system includes a dynamic preload tension feature for a tensioning element that actuates a distal end component of a surgical instrument. The surgical instrument includes a chassis at a proximal end of the surgical instrument, drive components mounted in the chassis, a distal end component at a distal end of the surgical instrument, a flexible tensioning element coupled between a first of the drive components and the distal end component, and a dynamic preload tensioner mounted in the chassis and coupled to a second of the drive components. The flexible tensioning element extends along a path. The dynamic preload tensioner is configured to be driven by the second of the drive components to be moved relative to the chassis and is positioned to change the path of the flexible tensioning element as the dynamic preload tensioner moves relative to the chassis.Type: ApplicationFiled: September 29, 2021Publication date: January 20, 2022Inventors: Matthew Aaron Wixey, William Burbank, Thomas Grosvenor Cooper, Patrick Flanagan, Nicholas H.
