Patent number: 8567655Abstract: A circular stapling instrument includes a casing, an anvil assembly, a staple driver, and a locking mechanism. The anvil assembly is configured to move back and forth between an open position away from the casing and a closed position adjacent the casing. The staple driver is configured to move within the casing from a pre-fired position to a fired position. The locking mechanism is configured to, whenever the anvil assembly is in the open position, automatically lock the staple driver in the pre-fired position preventing the staple driver from being moved to the fired position. The locking mechanism is also configured to, whenever the anvil assembly is in the closed position, automatically unlock the staple driver from the pre-fired position to allow the staple driver to be moved to the fired position.Type: GrantFiled: May 19, 2011Date of Patent: October 29, 2013Assignee: Ethicon Endo-Surgery, Inc.Inventors: Anil K.

Patent number: 8216255Abstract: A flexible endoscopic clip applier includes a flexible coil with a manual actuator coupled to one end and a jaw assembly coupled to the other end. A store of clips is arranged adjacent to the jaw assembly and a clip pusher is arranged adjacent to the store of clips. The actuator includes a lever for opening and closing the jaws, a knob for rotating the jaw assembly, and a crank for dispensing clips. The knob and the lever are coupled to a single control member which extends through the coil to a joiner where it is joined to a pair of pull wires coupled to the jaws. The crank is coupled to a second control member which is threaded along a distal portion. The threaded portion engages a threaded member near the pusher and is coupled to the pusher such that rotation of the threaded control member by the crank causes the pusher to be moved distally.Type: GrantFiled: June 14, 2004Date of Patent: July 10, 2012Assignee: Ethicon Endo-Surgery, Inc.Inventors: Kevin W. Smith, Jeffrey David Messerly, Barry Thomas Jamison, Peter K. Kratsch, Carlos Rivera, Jose Luis Francese, Kristin Nicole Werner Dawson, Chester O. Baxter, III, Juergen A. Kortenbach

Patent number: 8179074Abstract: Methods and devices are provided for rotating an end effector on a long, flexible medical device. The methods and devices utilize an actuator mechanism that is effective to rotate an end effector on the distal end of an elongate flexible shaft. The actuator mechanism is movable between a freely rotatable position and a rotationally resistant position. When the actuator mechanism is in a freely rotatable position, the actuator mechanism can be rotated to impart torque to the end effector, and thus at least a distal portion of the elongate shaft, to cause the end effector to rotate. In order to prevent the actuator mechanism from “freewheeling,” wherein the actuator mechanism freely rotates in an opposite direction upon release rather than the end effector rotating in the desired direction, the actuator mechanism can be moved to the rotationally resistant position.Type: GrantFiled: October 19, 2009Date of Patent: May 15, 2012Assignee: Ethicon Endo-Surgery, Inc.Inventors: Jeffrey David Messerly, Gary W. Knight, Barry Thomas Jamison, William Douglas Shaw, Jr.
