Patent number: 8360964Abstract: A wide angle HDTV endoscope includes at least two optical imaging channels. Lenses close each channel at the distal end of the endoscope. The imaging channels each have a different field of view in complementary directions, and have overlapping or cross-over field of view areas. Received images are transmitted along the longitudinal axis of the imaging channels of the endoscope to a camera head that contains a wide screen image sensing device. An external light source provides the required lighting and an image processing device can provide necessary software algorithms to format the images and to control any overlapping or cross-over field of view areas to obtain a single display image. In another arrangement, optical blocking elements provided at the proximal end of the endoscope or within the imaging channels eliminate portions of one or more images from the imaging channels so that at the cross-over areas only a single image is provided to the imaging device.Type: GrantFiled: December 5, 2008Date of Patent: January 29, 2013Assignee: Stryker CorporationInventor: Hasan Ertas

Patent number: 8246230Abstract: An LED based light source unit for an endoscopic imaging system produces illumination for a camera through an endoscope. The light source unit includes an array of LEDs mounted to a thermally conductive substrate, a light guide to collect light emitted from the LEDs and to couple the light into a group of optical fibers within the endoscope, and an interface to allow the light source unit to be removably attached to the endoscope at the endoscope's external light port. The LEDs therein may be overdriven by power for increased light output. When the LEDs reach their lifetime, the light source unit can be discarded.Type: GrantFiled: September 14, 2011Date of Patent: August 21, 2012Assignee: Stryker CorporationInventors: Erik F. D. Todd, Hasan Ertas, Andrew J. Hamel

Patent number: 8162822Abstract: A unit of equipment designed for use in endoscopic surgery includes radio frequency identification (RFID) circuitry and a network interface. The RFID circuitry can be used to store information of various types, such as component usage tracking information, user preferences, usage logs, error logs, device settings, etc. The network interface allows the unit to communicate over an external network with a remote server. Information, such as information stored in the RFID circuitry or in a separate memory, may be sent over the network to a desired destination, such as a server operated by the manufacturer of the equipment.Type: GrantFiled: May 11, 2011Date of Patent: April 24, 2012Assignee: Stryker CorporationInventors: Hasan Ertas, Ruzbeh Shariff, Sohail Desai, Brannon P. Wells, Rajeshwari Srinivasan

Patent number: 7668450Abstract: An LED based light source unit for an endoscopic imaging system produces illumination for a camera through an endoscope. The light source unit includes an array of LEDs mounted to a thermally conductive substrate. The light source unit is integrated into the proximal end of an endoscope and coupled directly to the optical fibers running to the tip of the endoscope. A plurality of such light source units may be integrated into the housing of an endoscope. Light emitted from each light source unit is directed to a distinctive section of the endoscope's tip and a doctor may control light output of each individual light source unit during a surgery.Type: GrantFiled: July 11, 2005Date of Patent: February 23, 2010Assignee: Stryker CorporationInventors: Erik F.

Patent number: 7498950Abstract: RFID circuitry is used in an endoscopic light source unit to track cumulative light bulb use information. An inductively powered RFID tag is affixed to the light bulb assembly, and communicates wirelessly with an RF transceiver within the light source unit via a low-frequency modulation wave. The RFID tag includes memory which stores a value representing cumulative duration of use of the light bulb. The transceiver reads the value from the RFID tag and communicates the value to control circuitry in the light source unit, which tracks use of the light bulb within the light source unit. Based on such tracking, the transceiver periodically updates the value in the RFID tag via the wireless link. Cumulative bulb usage hours is displayed on the light source unit. The RFID tag also may store a custom password and/or other information.Type: GrantFiled: August 30, 2005Date of Patent: March 3, 2009Assignee: Stryker CorporationInventors: Hasan Ertas, Brannon P.
