Publication number: 20060173289Abstract: Position detecting elements are disposed in an endoscope insertion portion at predetermined intervals. Even when the endoscope insertion portion is bent, position data representing the detected positions of the elements is used to infer or detect the shape of the insertion portion. A virtual element is disposed between adjoining elements so that a predetermined condition will be met. Position data of the virtual element is used together with the actually detected position data in order to interpolate data for the purpose of detecting the shape of the insertion portion. Consequently, as if a larger number of elements were disposed, the shape of the insertion portion can be detected highly precisely.Type: ApplicationFiled: August 22, 2003Publication date: August 3, 2006Inventors: Chieko Aizawa, Fumiyaki Onoda, Sumihiro Uchimura, Akira Taniguchi

Patent number: 6773393Abstract: A shape-of-endoscope detecting apparatus generally includes a shape detection unit, a marker, a marker locator unit, and a display control unit. The shape detection unit detects the shape of a portion of an insertion unit of an endoscope inserted into a subject, and produces graphic data expressing the shape thereof. The marker is placed near a position on the subject at which the endoscope is inserted. The marker locator unit acquires the location information of the marker. The display control unit graphically indicates on a display device the shape of the portion inserted into a body cavity, which is detected by the shape detection unit, using as a reference point the location information of the marker acquired by the marker locator. A shape-of-endoscope detecting method generally includes the steps of placing a marker, locating the marker, detecting the shape of the position of an endoscope inserted into a subject, and controlling the display of the detected shape.Type: GrantFiled: August 3, 2000Date of Patent: August 10, 2004Assignee: Olympus Optical Co., Ltd.Inventors: Akira Taniguchi, Sumihiro Uchimura, Yasuhiro Yoshizawa, Takeshi Kawabata, Masanao Hara, Kazutaka Tsuji, Chieko Aizawa

Patent number: 6773394Abstract: An endoscope shape detection system has a CPU included in a control unit. The CPU performs frequency sampling of digital data to calculate coordinates indicating the spatial positions of source coils incorporated in an insertion unit of an endoscope received in a patient and of marker coils placed on a patient. An inserted state of the insertion unit of the endoscope is estimated based on the calculated coordinate data indicating the positions of the source coils. Display data based on the shape of the endoscope is produced from the calculated coordinate data indicating the positions of the source coils, and output to a video RAM. Display data of the marker coils is produced from the calculated coordinate data indicating the positions of the marker coils, and output to the video RAM. Consequently, the positions of the markers are depicted together with the shape of the endoscope. The positional relationship between the insertion unit of the endoscope and a patient's body can therefore be ascertained.Type: GrantFiled: July 17, 2002Date of Patent: August 10, 2004Assignee: Olympus CorporationInventors: Akira Taniguchi, Chieko Aizawa, Yasuhiro Yoshizawa, Fumiyuki Onoda, Seiki Toriyama, Takeshi Kawabata, Katsuyoshi Sasagawa, Sumihiro Uchimura, Masanao Hara, Kazutaka Tsuji, Takayasu Miyagi, Hiroki Moriyama, Hiroshi Ishii, Yoshinao Oaki, Tsugio Okazaki, Jun Hasegawa, Yasuo Hirata, Tetsuo Nonami

Patent number: 6432041Abstract: A source coil line-break/short-circuit detecting circuit and a probe connection detecting circuit are provided to the source coil driving circuit unit of an endoscope shape detecting apparatus. The source coil line-break/short-circuit detecting circuit detects line-breaks and short-circuits of the source coils. The probe connection detecting circuit detects whether a connection exists with a probe. A marker coil line-break/short-circuit detecting circuit detects line-breaks and short-circuits of the marker coils. A marker connection detecting circuit detects whether a connection exists with a marker. Accordingly, using the apparatus without being connected to a probe or markers can be avoided by detecting the connection of the probe and markers by the probe connection detecting circuit and marker connection detecting circuit, respectively, when the system is energized, thereby avoiding detecting noise and consequently displaying a random image on the monitor.Type: GrantFiled: September 9, 1999Date of Patent: August 13, 2002Assignee: Olympus Optical Co., Ltd.Inventors: Akira Taniguchi, Chieko Aizawa, Yasuhiro Yoshizawa, Fumiyuki Onoda, Seiki Toriyama, Takeshi Kawabata, Katsuyoshi Sasagawa, Sumihiro Uchimura, Masanao Hara, Kazutaka Tsuji, Takayasu Miyagi, Hiroki Moriyama, Hiroshi Ishii, Yoshinao Oaki, Tsugio Okazaki, Jun Hasegawa, Yasuo Hirata

Patent number: 6059718Abstract: Magnetic-field generating elements or magnetic-field detecting elements are fixed into an insertion part having elasticity, which is inserted into a subject, by an insulating material while ensuring that forms of the respective magnetic-field generating elements or the respective magnetic-field detecting elements are not changed. Even when the insertion part is bent, there is no change in either the function of magnetic-field generation or the function of magnetic-field detection. Magnetic-field detecting elements or magnetic-field generating elements which are arranged at known positions around the subject are combined with each other to calculate three-dimensional positions of the magnetic-field generating elements or the magnetic-field detecting elements within the insertion part. Further, a form of the insertion part is estimated, and a three-dimensional image corresponding to a form of the insertion part is produced.Type: GrantFiled: June 2, 1995Date of Patent: May 9, 2000Assignee: Olympus Optical Co., Ltd.Inventors: Akira Taniguchi, Sumihiro Uchimura, Tsukasa Ishii, Masanao Hara, Nobuyuki Matsuura, Yasuo Miyano
