Patent number: 9370393Abstract: A forceps includes an end effector assembly including a pair of jaw members disposed in opposing relation relative to one another. At least one jaw member is moveable relative to the other between a spaced apart position, a first approximated position, and a second approximated position. The jaw members are configured to apply a pre-determined pressure to tissue disposed therebetween in each of the first and second approximated positions. A sealing pressure is applied to tissue disposed between the jaw members when the jaw members are in the first approximated position. A cutting pressure is applied to tissue disposed between the jaw members when the jaw members are in the second approximated position.Type: GrantFiled: February 10, 2014Date of Patent: June 21, 2016Assignee: COVIDIEN LPInventors: Edward M.

Patent number: 9044219Abstract: A surgical instrument for providing an ionized gas to a surgical site includes a receptacle for at least one cylinder of pressurized surgical gas and a frame having a port near the distal end for emitting the surgical gas. A passageway extending between the receptacle and the port delivers the surgical gas to the port. A puncture assembly for rupturing a seal on at least one cylinder to release the surgical gas into the passageway includes at least one bank for storing mechanical energy which may include at least one spring. An actuator is operable to actuate the at least one bank release the mechanical energy. At least one puncture pin is operatively coupled to the at least one bank such that energy released by the at least one bank is effective to move the at least one puncture pin relative to at least one cylinder to rupture the seal.Type: GrantFiled: December 20, 2012Date of Patent: June 2, 2015Assignee: Covidien LPInventors: Kathy E.

Patent number: 8083737Abstract: A surgical instrument for providing an ionized gas to a surgical site includes a receptacle for a cylinder of pressurized surgical gas and a frame having a port near the distal end for emitting the surgical gas. A passageway extending between the receptacle and the port delivers the surgical gas to an electrode that is adapted for connection to a source of electrosurgical energy. A puncture assembly for rupturing a seal on the cylinder to release the surgical gas into the passageway includes a spring movable between a first state for storing mechanical energy and a relaxed state. An actuator is operable to move the spring to the relaxed state. A puncture pin is operatively coupled to the spring such that energy released by movement of the spring to the relaxed state is effective to move the puncture pin relative to the cylinder to rupture the seal.Type: GrantFiled: August 26, 2009Date of Patent: December 27, 2011Assignee: TYCO Healthcare Group LPInventors: Kathy E.
