Patent number: 9095346Abstract: A surgical instrument includes a handle assembly having a lower portion with a hingedly attached end piece. When open, the end piece allows for receipt of a data card in a lower portion aperture. When closed, the end piece covers the aperture. In another version, the aperture is configured to receive a data card and battery pack assembly. Information is readable from and to the data card to measure a number of minutes the instrument was used during a procedure. Such information is communicated via wired or wireless communication to another device to determine a payment for the number of minutes used. Minutes are buyable from the device and writable onto the data card prior to insertion of the card into the instrument. In another version, a testing sequence is used in saline or via a tissue proxy to test the functionality of an instrument prior to a procedure.Type: GrantFiled: October 19, 2011Date of Patent: August 4, 2015Assignee: Ethicon Endo-Surgery, Inc.Inventors: Kevin L. Houser, Foster B. Stulen, Timothy G. Dietz, John W. Willis, Donna L. Korvick, Ashvani K. Madan, Aron O. Zingman

Publication number: 20130090576Abstract: A surgical system comprises an ultrasonic surgical instrument and a conduit. The conduit may be coupled with a vacuum source and/or a fluid source. The instrument comprises an ultrasonic transducer, a waveguide, and an end effector. The waveguide extends fully through the transducer, such that a distal end of the waveguide is distal to the distal end of the transducer and such that a proximal end of the waveguide is proximal to the proximal end of the transducer. The waveguide is operable to transmit ultrasonic vibrations from the transducer to the end effector. The waveguide defines a lumen in fluid communication with the conduit. The lumen is also in fluid communication with the end effector. The end effector may thus be used to deliver one or more of ultrasonic energy, suction, and/or fluid to a surgical site, in any suitable sequence or simultaneously.Type: ApplicationFiled: October 10, 2011Publication date: April 11, 2013Inventors: Foster B.

Publication number: 20120116379Abstract: An electrosurgical device comprises an end effector, a cutting member, and en electromechanical driver. The end effector comprises a pair of jaws that clamp tissue. The jaws include electrodes that deliver RF energy to clamped tissue. The cutting member cuts tissue clamped between the jaws. The electromechanical driver drives the cutting member. A control module commands the electromechanical driver, and regulates the delivery of RF energy to the electrodes, based on a combination of user input and feedback signals from the electrodes and from the electromechanical driver. The device may provide tactile feedback to the user through the user input feature, based on a load encountered by the cutting member. The device may alert the user when the exterior of end effector makes incidental contact with tissue, to avoid inadvertently burning the tissue. The device may include a removable battery pack to power the electromechanical driver and the electrodes.Type: ApplicationFiled: June 2, 2011Publication date: May 10, 2012Inventors: David C.
