Publication number: 20060165152Abstract: A probe cover for a tympanic thermometer probe comprises a generally tubular body having an opening for receiving the thermometer probe and an infrared transparent window at a distal end thereof. In one embodiment, a film support extends radially inward from the distal end of the body and supports an infrared transparent film spanning the window. The film support has an inner edge that is substantially free from corners turning in the plane of the window. A plurality of end ribs are spaced apart and disposed about an inner circumference of the distal end of the body to engage a distal end of the thermometer probe and form an insulating gap by preventing contact of the film by the thermometer probe. The insulating gap also extends proximally into spaces between the end ribs, reducing thermal contact between the thermometer probe and a circumferential inner surface of the probe cover.Type: ApplicationFiled: November 23, 2005Publication date: July 27, 2006Applicant: Sherwood Services AGInventors: Clarence Walker, Kevin Meier, Wayne Schuessler, David Swisher

Patent number: 7044949Abstract: A qualifying connection for an instrument attaches to a source of electrosurgery energy and to the instrument and has first and second parts coupled to the instrument and the source, respectively. Optical couplings on the connection transmit invisible energy to identify the instrument and are proximate on the first and second parts. A light modifier on the first part is proximal to the second part for modification of radiation in the infrared wavelengths so infrared transmitters encode signals and non-contact coded proximity detectors on the second part are the coupled detectors. Mechanical attachments include conjugating male and female portions which physically extend between the parts and matingly engage. An identifying circuit couples to the second part and responds to invisible light optically communicated across the couplings for verifying the type of instrument connected by the cable to the source.Type: GrantFiled: January 27, 2004Date of Patent: May 16, 2006Assignee: Sherwood Services AGInventors: James Henry Orszulak, Gary Lee Dobbins, Jr.

Patent number: 7033354Abstract: An electrosurgical electrode and electrosurgical generator system utilizing the same are disclosed capable of controlling or limiting the current per arc in real-time during an electrosurgical procedure. The conductive electrosurgical electrode is configured for being connected to an electrosurgical generator system and has a non-conductive, porous ceramic coating that “pinches” or splits the arc current generated by the electrosurgical generator system into the smaller diameter pores of the coating, effectively keeping the same current and voltage, but creating several smaller diameter arcs from one larger diameter arc. This has the effect of separating the arc current, effectively increasing the current frequency, resulting in a finer cut or other surgical effect. That is, the non-conductive, porous ceramic coating enables a low frequency current to achieve surgical results indicative of a high frequency current, while minimizing or preventing thermal damage to adjacent tissue.Type: GrantFiled: December 4, 2003Date of Patent: April 25, 2006Assignee: Sherwood Services AGInventor: David S. Keppel
