Publication number: 20230389957Abstract: An instrument guide is removably inserted into a proximal portion of a cannula and extends to a distal end of the cannula to guide and support multiple surgical instruments within the cannula. The instrument guide is designed to be manufactured by injection molding of plastic material. The instrument guide includes a tube and several radial walls connected to the tube to form passageways within the tube. The radial walls are joined to a core where they intersect. The tube and radial walls have substantially the same wall thickness and the core has a minimum diameter that is substantially larger than the wall thickness to facilitate delivery of plastic material. Portions of the tube and radial walls are thinner than the general wall and rib thickness to form guideways that support surgical instruments within the passageways. Channels may be formed on an outside of the tube to deliver insufflation gas.Type: ApplicationFiled: June 7, 2023Publication date: December 7, 2023Inventor: Tyler J. Morrissette

Publication number: 20230363840Abstract: A cannula mount for a surgical system includes a body configured to receive a portion of a cannula in a mounted state at the cannula mount; a pair of clamping components coupled to the body and configured to clamp the portion of the cannula in the mounted state of the cannula; and a latch assembly pivotably coupled to the body and slidably coupled to a clamping component of the pair of clamping components. At least one of the pair of clamping components is pivotable relative to the body to move the pair of clamping components between a first state to unclamp a cannula mounted at the cannula mount and a second state to clamp a cannula mounted at the cannula mount. Pivoting motion of the latch assembly relative to the body causes a portion of the latch assembly to slide along the clamping component and change a state of the pair of clamping components from an unlocked state to a locked state in the second state of the pair of clamping components.Type: ApplicationFiled: May 16, 2023Publication date: November 16, 2023Applicant: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: Allen C.

Patent number: 11678945Abstract: A cannula mount for a surgical system includes pivotable clamping arm with a first feature configured to engage a second feature of the cannula positioned in the cannula mount. The clamping arm comprises a cam follower surface. The cannula mount further comprises a latch member movable between at least a first position and a second position, and the latch member comprises a cam surface. On the condition that the latch member is in the first position, the cam surface engages the cam follower surface of the clamping arm to actuate the clamping arm to a closed position in which the first feature engages the second feature. On the condition the cam member is in the second position, the clamping arm is free to move to an open position in which the first feature does not engage the second feature. Devices and methods relate to cannula mounts.Type: GrantFiled: November 22, 2021Date of Patent: June 20, 2023Assignee: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: Allen C. Thompson, Randal P.

Publication number: 20230043818Abstract: Gas-tight seal assemblies for use during minimally invasive surgery include various aspects. A wiper seal includes a sealing portion and a surrounding flex portion. Upper and lower faces of the sealing portions are angled with reference to an inserted instrument, the upper face's angle being more acute with reference to the instrument's shaft than the lower face's angle. The flex portion is corrugated, support ribs are in one or more corrugation grooves, and the support ribs allow the groove to easily collapse but resist the groove widening. The support ribs also prevent the sealing portion from inverting. An instrument insertion guide is positioned over the sealing portion and moves laterally with the sealing portion. A latch piece removably secures the seal assembly to a cannula. An anti-inversion piece prevents the wiper seal from inverting when an instrument is withdrawn.Type: ApplicationFiled: October 13, 2022Publication date: February 9, 2023Inventors: Robert C. Reid, Justin Krom, Tyler J. Morrissette, Joseph P. Orban, III, William A. Burbank, David DeTroy

Patent number: 11446105Abstract: An instrument sterile drape includes a plastic sheet and an instrument sterile adapter (ISA) coupled to the plastic sheet. The ISA includes bottom and top plates located on opposite sides of the plastic sheet plate and joined together. A passage in the bottom plate allows an instrument carriage flux connection to pass through the plastic sheet and the bottom plate to be adjacent to the top plate. The top plate includes a signal transmission area that will be adjacent to an upper surface of the flux connection of the instrument carriage. A flux connector may close an opening in the signal transmission area of the top plate and provide a path for an electrical or optical signal. The signal transmission area of the top plate may be thinned to allow an RFID sensor to be closer to an RFID device in a surgical instrument attached to the instrument sterile adapter.Type: GrantFiled: July 29, 2019Date of Patent: September 20, 2022Assignee: Intuitive Surgical Operations, Inc.Inventors: Gregory W.

Patent number: 11129683Abstract: A teleoperational medical system comprises an input device and a manipulator configured to couple with and move an instrument. The system also comprises a control system including one or more processors. In response to a determination that the instrument is inserted into an instrument workspace in a corresponding direction to a field of view of the workspace, the control system is configured to map movement of the input device to movement of the instrument according to a first mapping. In response to a determination that the instrument is inserted into the instrument workspace in a non-corresponding direction to the field of view, the control system is configured to map movement of the input device to movement of the instrument according to a second mapping.
