Patent number: 9877777Abstract: A deployment and retraction mechanism for deploying and retracting a deployable component of a surgical instrument includes a gear assembly, a slider, and one or more actuators. The slider is translatable between a proximal position, corresponding to a storage condition of the deployable component, and a distal position, corresponding to a use condition of the deployable component. The actuator(s) is coupled to the gear assembly and is movable from an un-actuated position to an actuated position. The gear assembly is configured such that a full actuation and subsequent release of the actuator(s) translates the slider from one of the proximal or distal positions to the other of the proximal or distal positions while a partial actuation and subsequent release of the actuator(s) translates the slider from one of the proximal or distal positions to an intermediate position and back to the one of the proximal or distal positions.Type: GrantFiled: July 17, 2015Date of Patent: January 30, 2018Assignee: COVIDIEN LPInventors: Kurt J. Anglese, Jason T. Sanders, Dylan R. Kingsley, Gregory P. Hertrich

Patent number: 9820806Abstract: An electrosurgical forceps includes a housing having a shaft affixed thereto, the shaft including jaw members at a distal end thereof. The forceps also includes a switch assembly that includes a supporting member, a flexible membrane circuit having snap dome switch contacts operably fixed thereto, and ergonomically-contoured keytops. The switch assembly provides at least one monopolar activation switch, and a bipolar activation switch. The forceps also include a drive mechanism which causes the jaw members to move relative to one another for manipulating tissue. A monopolar safety switch is incorporated into the switch assembly which cooperates with the drive mechanism to inhibit the monopolar activation switch when the jaw members are in an open position.Type: GrantFiled: September 29, 2009Date of Patent: November 21, 2017Assignee: Covidien LPInventors: Weng-Kai K. Lee, Jeffrey R. Townsend, Scott N. LaCosta, Jason T. Sanders, Grant T. Sims

Publication number: 20170065332Abstract: A forceps is provided and includes a housing having a shaft. An end effector assembly operatively connects to a distal end of the shaft and includes a pair of first and second jaw members. One or both of the first and second jaw members is movable relative to the other jaw member from a clamping position to an open position. A resilient member operably couples to at least one of the first and second jaw members. The resilient member is configured to bias the first and second jaw members in the clamping position and provide a closure force on tissue disposed therebetween.Type: ApplicationFiled: November 21, 2016Publication date: March 9, 2017Inventors: DAVID M.

Publication number: 20160100881Abstract: A method for manufacturing an end effector assembly includes providing first and second jaw members moveable relative to one another about a pivot between a first, spaced-apart position and a second, approximated position. One of the first and second jaw members includes a cavity defined therein and the other of the first and second jaw members includes a stop member configured to be inserted into the cavity. A gap-setting gauge is grasped between the first and second jaw members to define a gap-distance between the jaw members equivalent to a thickness of the gap-setting gauge. The first and second jaw members are set such that the jaw members are prevented from approximation beyond the gap-distance.Type: ApplicationFiled: December 15, 2015Publication date: April 14, 2016Inventors: JOANNA ACKLEY, JAMES D.

Publication number: 20160074102Abstract: A surgical instrument includes a housing having a shaft extending distally therefrom, an end effector assembly disposed at a distal end of the shaft, a handle assembly coupled to the housing for manipulating the end effector assembly, a deployable assembly, at least one actuator for deploying and retracting the deployable assembly, and a closure member. The closure member is keyed to the actuator(s) and operably positioned relative to the movable handle of the handle assembly such that, upon rotation of the actuator(s) relative to the housing from an un-actuated position to an actuated position, the closure member is urged into contact with the movable handle to urge the movable handle from an initial position to a compressed position, thereby moving the end effector assembly to an approximated position.Type: ApplicationFiled: July 17, 2015Publication date: March 17, 2016Inventors: Kurt J.

Publication number: 20160074107Abstract: A deployment and retraction mechanism for a surgical instrument includes a gear box defining a longitudinal slot, a slider, a ring gear, and a planet gear. The slider is configured to engage a deployable component of the surgical instrument and is translatable along the longitudinal slot between a proximal end, corresponding to a storage condition of the deployable component, and a distal end, corresponding to a use condition of the deployable component. The planet gear is operably engaged with the ring gear and configured to orbit within the ring gear. The planet gear includes an off-center pin rotatably supporting the slider thereon. The planet gear and ring gear are configured such that a one-half orbit of the planet gear within the ring gear translates the slider from one end of the longitudinal slot to the other end of the longitudinal slot.Type: ApplicationFiled: July 17, 2015Publication date: March 17, 2016Inventors: KURT J.
