Publication number: 20230338051Abstract: A surgical tool includes a drive housing, a shaft extending from the drive housing and including an inner grounding shaft, an end effector coupled to the shaft and having opposing jaws, a firing rod extending within the inner grounding shaft and terminating at a cutting element, and an unclamp lockout mechanism provided within the drive housing and including a pawl rotatably mounted to the inner grounding shaft and pivotable between a stowed position, where the pawl is received within an aperture defined in the inner grounding shaft, and a deployed position, where the pawl protrudes out of the aperture, and a biasing device that biases the pawl toward the stowed position. When the pawl is in the stowed position, the pawl is received within a cutout defined by the firing rod, and moving the firing rod distally overcomes the biasing device and urges the pawl to the deployed position.Type: ApplicationFiled: June 30, 2023Publication date: October 26, 2023Applicant: CILAG GMBH INTERNATIONALInventors: Robert Louis KOCH, JR., Mark D.

Patent number: 11701136Abstract: A surgical tool includes a drive housing, a shaft extending from the drive housing, an end effector at an end of the shaft and having opposing jaws and a cutting element, and an unclamp lockout mechanism. The unclamp lockout mechanism including a pawl rotatably mounted to the shaft and positioned proximal to a closure yoke operatively coupled to the shaft, the pawl being pivotable between a stowed position, where the pawl is received within an aperture of the shaft, and a deployed position, where the pawl protrudes out of the aperture, and a biasing device that biases the pawl toward the stowed position. When the pawl is in the stowed position, the closure yoke is movable to a proximal position over at least a portion of the pawl to open the opposing jaws. When the pawl is in the deployed position, the closure yoke is prevented from moving to the proximal position.Type: GrantFiled: April 16, 2019Date of Patent: July 18, 2023Assignee: Cilag GmbH InternationalInventors: Robert Louis Koch, Jr., Mark D.

Patent number: 11666404Abstract: A surgical tool includes a drive housing, a shaft extending from the drive housing, an end effector at an end of the shaft and having opposing jaws and a cutting element, and an articulable wrist configured to rotate the end effector within a plane. The wrist is articulated via antagonistic translation of a pair of drive members. Various systems are provided for homing one or more drive inputs that cause movement in the wrist and/or the end effector, or for controlling articulation of the drive inputs.Type: GrantFiled: August 28, 2019Date of Patent: June 6, 2023Inventors: Mark D.

Patent number: 11559366Abstract: A method includes grasping a user input device in communication with a surgical tool of a robotic surgical system, the surgical tool including an end effector with opposing jaws, squeezing the user input device and thereby actuating a motor that closes the jaws and clamps down on tissue at a surgical site, and calculating with a computer system in communication with the surgical tool work completed by the motor to close the jaws and clamp down on the tissue. The computer system generates one or more effort indicators when the work completed by the motor meets or exceeds one or more predetermined work increments corresponding to operation of the motor, and communicates the one or more effort indicators to an operator.Type: GrantFiled: September 30, 2019Date of Patent: January 24, 2023Assignee: CILAG GMBH INTERNATIONALInventors: Mark D.

Patent number: 11439474Abstract: A surgical tool includes a drive housing having a shaft extending distally therefrom, first and second drive members extending distally from the drive housing along the shaft, and first and second translating gears rotationally fixed to the shaft within the drive housing and operatively coupled to the first and second drive members, respectively. First and second drive gears are rotatably mounted within the drive housing to act on the first and second translating gears, respectively. Rotating the first and second drive gears in opposite angular directions causes the first and second translating gears to move axially along the shaft in opposing directions and thereby move the first and second drive members. Rotating the first and second drive gears in a same angular direction causes the first and second translating gears to rotate the shaft about a longitudinal axis.Type: GrantFiled: October 25, 2018Date of Patent: September 13, 2022Assignee: CILAG GMBH INTERNATIONALInventor: Kris Eren Kallenberger

Publication number: 20220249187Abstract: A robotic surgical tool includes a handle and an elongate shaft extendable through the handle and including an outer proximal tube and an inner spline rotatably received within the outer proximal tube. A first actuation system is housed within the handle and operable to rotate the inner spline relative to the outer proximal tube and thereby transfer torque to a proximal or distal end of the shaft. A second actuation system is housed within the handle and operable to drive the outer proximal tube and thereby advance or retract the elongate shaft in z-axis translation through the handle.Type: ApplicationFiled: February 11, 2021Publication date: August 11, 2022Applicant: Ethicon LLCInventor: Kris Eren KALLENBERGER

Patent number: 11382704Abstract: A surgical tool includes a drive housing, a closure tube that extends from the drive housing, an end effector arranged at an end of the closure tube and having opposing jaws, and a closure yoke mounted to the closure tube and having a projection extending therefrom. A gearing assembly includes one or more spur gears attached to a corresponding one or more drive shafts such that rotation of the one or more drive shafts correspondingly rotates the one or more spur gears, and a closure cam gear positioned to intermesh with the one or more spur gears and defining a profile that receives the projection. Rotating the one or more spur gears causes the closure cam gear to rotate, which causes the projection to traverse the profile, and the projection traversing the profile urges the closure yoke and the closure tube to linearly displace and thereby actuate the jaws.Type: GrantFiled: August 28, 2019Date of Patent: July 12, 2022Assignee: CILAG GMBH INTERNATIONALInventors: Mark D.
