Publication number: 20160310208Abstract: An electrosurgical device comprises a body, an end effector, a cutting member, and a shaft. The end effector includes a pair of jaws that are operable to deliver RF energy to tissue that is clamped between the jaws. The cutting member is operable to sever tissue that is clamped between the jaws. The shaft extends between the body and the end effector. The shaft includes an articulation section that is operable to selectively position the end effector at non-parallel positions relative to the longitudinal axis of the shaft. Some versions include a rotation section that is distal to the articulation section. The rotation section is operable to rotate the end effector relative to the articulation section.Type: ApplicationFiled: July 7, 2016Publication date: October 27, 2016Inventors: Barry C. Worrell, David K. Norvell, Charles J. Scheib, Frederick E. Shelton, IV, Geoffrey S. Strobl, Jeffrey S. Swayze, Gregory A. Trees, Jason E. Zerkle, Kevin M. Montgomery

Patent number: 8872435Abstract: A light is provided having a base unit, an arm extending from the base unit, and a lamp head coupled to the arm. The lamp head includes an LED configured to provide light based on an input drive current, an optical mixing element configured to collect the light produced by the LED and a zoom lens configured to adjust an output size of a spot generated by the light collected in the mixing element. A controller receives DC power from the base unit through the arm. The controller is configured to set the input drive current for the LED to control an output light density of the spot in response to an operator selected input and configured to adjust the output light density of the spot in response to a change in the size of the spot.Type: GrantFiled: February 15, 2011Date of Patent: October 28, 2014Assignee: Midmark CorporationInventors: Melvyn H. Kreitzer, Kevin M. Montgomery, Jacob Moskovich, Brian D. Rau, Thomas L. Treon

Publication number: 20140263542Abstract: A surgical instrument can comprise a handle, a shaft extending from the handle, and an end effector rotatably coupled to the shaft by an articulation joint. The surgical instrument can further include a staple cartridge positioned within the end effector and a firing drive operably coupled with a trigger wherein the operation of the trigger can advance and/or retract a firing member of the firing drive relative to the end effector. The surgical instrument can further comprise an articulation drive which is selectively engageable with the firing drive. When the articulation drive is engaged with the firing drive, the operation of the firing drive can operate the articulation drive and articulate the end effector. When the articulation drive is not engaged with the firing drive, the firing drive can be operated independently of the articulation drive.Type: ApplicationFiled: March 14, 2013Publication date: September 18, 2014Inventors: Richard L. Leimbach, Kevin M. Montgomery, Wendy A. Kerr, Thomas W. Lytle, IV, Mark D. Overmyer, Brett E. Swensgard

Publication number: 20140121465Abstract: The present invention generally provides methods and devices for removing fluid from a surgical instrument. Surgical access devices and seal systems are generally provided having one or more valves or seal assemblies to create a closed system between the outside environment and the environment in which the surgical access device is being inserted. The devices of systems can also include a fluid remover in the form of a sorbent element, a scraper element, a wicking element, or any combination thereof that is configured to remove fluid from a working channel of the device or system and/or from a surgical instrument inserted therethrough.Type: ApplicationFiled: January 8, 2014Publication date: May 1, 2014Applicant: ETHICON ENDO-SURGERY, INC.Inventors: Patrick J. Minnelli, Kevin M. Montgomery

Publication number: 20120078243Abstract: An electrosurgical device includes a body, an end effector, a cutting member, and a shaft. The end effector comprises a pair of jaws and at least one electrode that is operable to deliver RF energy to tissue clamped between the jaws. The cutting member is operable to cut tissue clamped between the jaws. The shaft includes an articulation section that is operable to selectively position the end effector at non-parallel positions relative to the longitudinal axis of the shaft. The body includes a controller operable to selectively actuate the articulation section. The controller may include a rotary knob, a pivoting knob, or a pivoting fin, among other things. An electrical coupling may contact a conductive moving member along at least two axes. A resiliently biased lever may assist a trigger in returning from an actuated position to a home position.Type: ApplicationFiled: September 19, 2011Publication date: March 29, 2012Inventors: Barry C. Worrell, Zhifan F. Huang, Jason R. Lesko, Matthew C. Miller, Geoffrey S. Strobl, Gregory A. Trees, Charles S. Black, William E. Clem, Emron J. Henry, Kevin M. Montgomery
