Patent number: 9060807Abstract: A lesion identification system for surgical operations has a light marker adapted for placement in the vicinity of a lesion inside an organ of an organism, and a location-identifying device detecting a light emitted from the light marker at an outside of the organ for identifying a location of the lesion. The marker includes a light emitter and an engagement member associated with the emitter to be engageable with a wall of the organ. The engagement member includes a clip. The light emitter emits light with a wavelength in a near-infrared range. The device includes an endoscope comprising an inserter section having an image pickup element picking up a reflected light, involving the light from the light marker, at an outside of the organ, and an image pickup unit allowing the reflected light, picked by the image pickup element, to be generated as an image for display on a monitor.Type: GrantFiled: March 8, 2011Date of Patent: June 23, 2015Assignee: OLYMPUS CORPORATIONInventors: Kunihide Kaji, Shinji Hatta, Keita Suzuki, Yuichi Morizane, Toshiyuki Takara, Tatsuya Saito, Takeshi Takigawa

Patent number: 7658710Abstract: An endoscope system includes a light source for supplying three narrow wavelength bands including one wavelength band for exciting fluorescence, an excitation light cut filter for transmitting light having a wavelength greater than either 470 nm or 490 nm, and an image capturing unit for capturing the light transmitted by the excitation light cut filter and outputting three wavelength band signals corresponding to the three narrow wavelength bands of the light source. Also included are first, second and third frame memories for inputting and storing the three wavelength band signals, respectively, and first, second and third output ends for outputting first, second and third color signals, respectively, to a monitor for displaying an image. An image processor receives signals from the first, second and third frame memories respectively and selects among the first output end, the second output end and third output end for outputting the received signals to the monitor.Type: GrantFiled: December 18, 2006Date of Patent: February 9, 2010Assignee: Olympus CorporationInventors: Hitoshi Ueno, Takeshi Ozawa, Kazunari Nakamura, Isami Hirao, Hiroshi Ibe, Koichi Yoshimitsu, Yuichi Morizane, Mamoru Kaneko, Shunya Akimoto, Masaki Terakubo, Katsuichi Imaizumi, Nobuyuki Doguchi, Sakae Takehana, Kazuhiro Gono

Patent number: 7226412Abstract: An endoscope system in accordance with an embodiment of the present invention includes an endoscope with a monochrome image pickup device for capturing reflected light and fluorescence from the body cavity, an excitation light cut filter which is installed in front of the image pickup device for shielding excitation light, and an endoscope ID which includes information on the type of the endoscope. A light source unit includes a first switching filter that irradiates light including excitation light for a fluorescent image mode and a filter for generating continuous light for a normal-light image mode. The filters switch based between the fluorescent image mode and the normal-light image mode. A second switching filter with a limiting filter that limits certain wavelengths of excitation light of the first switching filter is provided. The limiting filters are switched according to the endoscope ID or observation state in the fluorescence mode.Type: GrantFiled: May 25, 2004Date of Patent: June 5, 2007Assignee: Olympus CorporationInventors: Hitoshi Ueno, Takeshi Ozawa, Kazunari Nakamura, Isami Hirao, Hiroshi Ibe, Koichi Yoshimitsu, Yuichi Morizane, Mamoru Kaneko, Shunya Akimoto, Masaki Terakubo, Katsuichi Imaizumi, Nobuyuki Doguchi, Sakae Takehana, Kazuhiro Gono

Patent number: 6960165Abstract: In a light source unit, a switchable filter section in which an RGB filter and a fluorescence observation filter can be shifted into the light path is disposed in front of a lamp. When fluorescence image mode is selected, excitation light in a part of the wavelength band of the blue wavelength band is supplied to an electronic endoscope, and the excitation light which is reflected by the subject is shielded by an excitation light shielding filter situated in front of a CCD, whereby a fluorescence image can be obtained. On the other hand, if normal-light image mode is selected, then R, G, B light is supplied sequentially, and even under illumination of B light, the color component image in the wavelength bands which are not shielded by the excitation light shielding filter are captured, thereby yielding a normal-light image also, and hence making it possible to capture both a fluorescence image and a normal-light image by means of a single image pickup element.Type: GrantFiled: May 14, 2002Date of Patent: November 1, 2005Assignee: Olympus CorporationInventors: Hitoshi Ueno, Takeshi Ozawa, Kazunari Nakamura, Isami Hirao, Hiroshi Ibe, Koichi Yoshimitsu, Yuichi Morizane, Mamoru Kaneko, Shunya Akimoto, Masaki Terakubo, Katsuichi Imaizumi, Nobuyuki Doguchi, Sakae Takehana
