Patent number: 10271836Abstract: An endoscopic stitching device includes an actuation shaft, a tool assembly, and a drive assembly. The tool assembly includes a suture needle and a pair of jaws transitionable between open and closed positions. Each jaw includes a needle engaging blade slidably supported thereon. Each needle engaging blade is transitionable between an extended position in which the needle engaging blade engages the suture needle and a retracted position in which the needle engaging blade is disengaged from the suture needle. The drive assembly includes first, second, and third electrical actuators. The first actuator is operatively coupled with the actuation shaft to cause axial displacement of the actuation shaft. The axial displacement of the actuation shaft causes opening and closing of the pair of jaws. The second and third actuators are operatively coupled with the needle engaging blades to provide axial displacement of the needle engaging blades.Type: GrantFiled: November 17, 2016Date of Patent: April 30, 2019Assignee: Covidien LPInventors: Stanislaw Marczyk, Russell Pribanic, Anthony Calderoni, Christopher Switalski

Publication number: 20170296176Abstract: An adapter assembly includes a switch actuator, an actuation bar, and a latch. The switch actuator is movable between a proximal position, in which the switch actuator actuates a switch, and a distal position. The latch is movable between a first position, in which the latch permits proximal movement of the switch actuator, and a second position, in which the latch prevents proximal movement of the switch actuator. The latch is configured to move from the first position toward the second position in response to the actuation bar moving toward a proximal position.Type: ApplicationFiled: June 2, 2017Publication date: October 19, 2017Inventors: Elizabeth Contini, Kelly Valentine, Thomas Wingardner, David McCuen, Matthew Chowaniec, John Beardsley, Russell Pribanic, Xingrui Chen, Christopher Switalski

Patent number: 9345480Abstract: A surgical kit is disclosed. The kit comprises a surgical instrument, a loading unit, and a plurality of cartridge members. The surgical instrument includes a handle assembly, and an elongated portion extending distally from the handle assembly and defining a longitudinal axis. The loading unit is configured for selective engagement with a distal portion of the elongated portion. The loading unit including an anvil assembly and a cartridge channel. Each cartridge member includes a plurality of retention slots with at least some of the slots including fasteners therein. Each cartridge member is configured for selective mechanical engagement with the cartridge channel, and includes a longitudinal length and a working length.
