Patent number: 12102402Abstract: A robotic surgical tool includes a handle having a drive input and a spline, a bailout ring arranged at the handle, and a slipper clutch mechanism received within the bailout ring. The slipper clutch mechanism including a slip carrier rotationally fixed to the bailout ring and defining a vertical slot that slidably receives a pin, a first ring arranged within the slip carrier and defining a first interface, a second ring arranged within the slip carrier atop the first ring and defining a second interface, and a pinion gear operatively coupled to the spline and arranged to intermesh with radial gear teeth defined on the second ring. Manual rotation of the bailout ring rotates the slip carrier and the pin and thereby rotates the first and second ring in succession to rotate the spline and manually bail out a function of the robotic surgical tool.Type: GrantFiled: February 11, 2021Date of Patent: October 1, 2024Assignee: Cilag GmbH InternationalInventors: Raffaele Definis, Benjamin L.

Patent number: 11974823Abstract: A robotic surgical tool comprises a stage assembly and a core assembly removably mountable to the stage assembly. The stage assembly may comprise a lead screw and at least one spline extendable between first and second ends of the stage assembly, and a nut rotatably mounted to the lead screw to translate between the first and second ends upon rotation of the lead screw. The core assembly may comprise a drive housing that is movably mountable to the stage assembly to translate, with the nut, between the first and second ends of the stage assembly. The surgical tool may also comprise a shroud assembly having a primary shroud and a secondary shroud, the primary shroud at least partially enclosing the core assembly when installed on the stage assembly, and the secondary shroud being movable between a first position, where the secondary shroud occludes an opening in the primary shroud, and a second position, where the opening in the primary shroud is exposed.Type: GrantFiled: July 23, 2020Date of Patent: May 7, 2024Assignee: Cilag GmbH InternationalInventors: Andrew T.

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.

Patent number: 11173267Abstract: An adjustable tracheostoma valve includes a housing having a first opening that is adapted to open to a tracheostoma and a second opening that opens to ambient. The housing includes a lower housing portion defining the first opening and an upper housing portion movably attached to the lower housing portion and defining the second opening. A closure member is disposed in the housing and adapted to close the second opening. A flexible membrane includes a first region connected to the closure member and a plurality of spiral shaped legs extending from the first region and connected to the housing. The upper and lower housings are axially adjustable relative to one another to adjust an amount of air flow through the valve that would cause closure of the closure member.
