Publication number: 20230338102Abstract: A robotic surgical tool includes a handle providing a plurality of drive inputs, an elongate shaft including a plurality of sliding rack gears movably nested within a corresponding plurality of longitudinal channels defined along the shaft, and an end effector arranged at a distal end of the shaft and an articulable wrist interposing the end effector and the distal end. An actuation system housed in the handle actuates the drive inputs to move the sliding rack gears and thereby causes operation of at least one of the end effector and the wrist. A tailpiece is arranged at a proximal end of the shaft and is operably coupled to the sliding rack gears, the tailpiece includes a housing and a manual actuation device mounted to the housing and manually actuatable to act on the sliding rack gears and thereby operate at least one of the end effector and the wrist.Type: ApplicationFiled: April 26, 2022Publication date: October 26, 2023Applicant: Cilag GmbH InternationalInventors: Spencer WITTE, Benjamin David DICKERSON, Aren Calder HILL, Trent Michael CALLAN, Dillon CAREY, Matthew STONE, Chris BIRRI, Reed ARENBURG

Publication number: 20230310101Abstract: A robotic surgical tool includes a handle and an instrument driver releasably coupled to the handle, an elongate shaft extendable through the handle and the instrument driver, and a decoupler interposing the handle and the instrument driver. The decoupler includes an insertion assembly actuatable to move the shaft, an insertion transmission gear driven by the insertion assembly, and a dwell slip clutch including an input clutch gear and an output clutch gear, the dwell slip clutch being movable between collapsed and expanded states. A lockout ring extends about the decoupler housing, and a latch ring extends about the decoupler housing and is axially offset from the lockout ring. Fully retracting the shaft moves the dwell slip clutch to the compressed state to drive the output clutch gear against the lockout ring, thereby enabling latch ring to move to an unlocked position that separates the handle from the instrument driver.Type: ApplicationFiled: April 1, 2022Publication date: October 5, 2023Applicant: Cilag GmbH InternationalInventor: Benjamin David DICKERSON

Patent number: 11771509Abstract: A robotic surgical tool includes a drive housing having first and second ends, a spline extending between the ends and including a drive gear that rotates with spline rotation, and a carriage mounted to the spline. A shaft extends from the carriage, penetrates the first end, and has an end effector arranged at a distal end. An activating mechanism is housed in the carriage and includes an input gear operatively coupled to the drive gear such that rotation of the drive gear correspondingly rotates the input gear, and a firing rod defining external threads threadably engageable with internal threads of the input gear. The firing rod is coupled to a knife at the end effector such that movement of the firing rod correspondingly moves the knife in the same direction. The drive gear is rotated to rotate the input gear and thereby move the firing rod and the knife.Type: GrantFiled: June 18, 2020Date of Patent: October 3, 2023Assignee: Cilag GmbH InternationalInventors: Andrew T. Beckman, Charles J. Scheib, Travis Michael Schuh, Benjamin David Dickerson, Jason Alan Hill

Patent number: 11751960Abstract: A robotic surgical tool includes a drive housing having a first end, a second end, and a lead screw extending between the first and second ends, a carriage movably mounted to the lead screw at a carriage nut secured to the carriage, and an elongate shaft extending from the carriage and extending through the first end, the shaft having an end effector arranged at a distal end thereof. Rotation of the lead screw moves the carriage and the carriage nut axially between the first and second ends and thereby moves the end effector distally or proximally.Type: GrantFiled: June 18, 2020Date of Patent: September 12, 2023Assignee: Cilag GmbH InternationalInventors: Andrew T. Beckman, Charles J. Scheib, Travis Michael Schuh, Benjamin David Dickerson, Aren Calder Hill, Yanan Huang

Patent number: 11744661Abstract: A robotic surgical tool includes a drive housing having a first end, a second end, and a lead screw extending between the first and second ends, a carriage movably mounted to the lead screw at a carriage nut secured to the carriage, and an activating mechanism including a drive gear rotatably mounted to the carriage and rotatable to actuate the activating mechanism. A torsion cable extends between the drive gear and a drive input arranged at the first end, wherein rotating the drive input rotates the torsion cable and thereby transmits a torsional load along the torsion cable to the drive gear to actuate the activating mechanism.Type: GrantFiled: June 18, 2020Date of Patent: September 5, 2023Assignee: Cilag GmbH InternationalInventors: Andrew T. Beckman, Charles J. Scheib, Travis Michael Schuh, Benjamin David Dickerson, Steven G. Hall

Patent number: 11678870Abstract: A surgical tool comprising a drive housing having a first end and a second end, a spline extending between the first and second ends, a carriage provided in the drive housing and movable between the first and second ends, and a mechanism for manually actuating the spline. The mechanism may be arranged at the first or second end of the drive housing. The mechanism may further include a frame, a spline coupling rotatably mounted to the frame to receive an end of the spline, and a ring gear rotatable about the frame and operatively coupled to a pinion gear attached to the spline coupling such that rotation of the ring gear about the frame correspondingly actuates the spline.Type: GrantFiled: September 29, 2020Date of Patent: June 20, 2023Inventors: Andrew T. Beckman, Charles J. Scheib, Travis Michael Schuh, Benjamin David Dickerson

Patent number: 11622827Abstract: A robotic surgical tool includes a drive housing having first and second ends, at least one spline extending between the first and second ends and including a drive gear that rotates with rotation of the spline, and a carriage mounted to the spline. A closure tube extends from the carriage through the first end and has an end effector arranged at a distal end. An activating mechanism is housed in the carriage and includes a driven gear coupled to the drive gear such that rotation of the drive gear rotates the driven gear, and a carrier arranged at a proximal end of the closure tube and coupled to the driven gear such that rotation of the driven gear moves the carrier and the closure tube axially along a longitudinal axis of the closure tube. Moving the closure tube along the longitudinal axis closes or opens end effector jaws.Type: GrantFiled: June 18, 2020Date of Patent: April 11, 2023Assignee: CILAG GMBH INTERNATIONALInventors: Andrew T. Beckman, Charles J. Scheib, Travis Michael Schuh, Benjamin David Dickerson, Jason Alan Hill, Neil Markwardt
