Patent number: 8998801Abstract: Contact between a face to be pressed and a cam face in an interaxial direction T of two inner guide sheaths is set so that a contact width H therebetween is shorter than an interaxial distance L, and so that the contact position is located between axes of the two inner guide sheaths. As a result, even in a case where external diameters of two inner guide sheaths that form a pair are slightly different to each other, a braking member can be tilted to cause a contact face to simultaneously come in contact with the respective inner guide sheaths, and a pressing force from an eccentric cam can be transmitted equally to the respective inner guide sheaths.Type: GrantFiled: December 10, 2013Date of Patent: April 7, 2015Assignee: Olympus Medical Systems Corp.Inventor: Tsugio Okazaki

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: 6589163Abstract: An endoscope shape detecting system displays an endoscope image and an insertion form image simultaneously on a display means. A first memory stores an endoscope image and a second memory stores an insertion form image. A control device controls a switching action such that the insertion form image is output to the display means during a period wherein the output of the endoscope image to the display means is turned off and stored in the first memory means, and that the output of the insertion form image to the display means is turned off and stored in the second memory during the period wherein the output of the endoscope image to the display is turned on. In addition, a control device is provided that controls the storing action such that a first period for storing endoscope images in the first memory and a second period for storing output signals from a magnetic field detecting device in the second memory do not overlap.Type: GrantFiled: June 24, 2002Date of Patent: July 8, 2003Assignee: Olympus Optical Co., Ltd.Inventors: Chieko Aizawa, Akira Taniguchi, Jun Hasegawa, Katsuyoshi Sasagawa, Seiki Toriyama, Takayasu Miyagi, Tsugio Okazaki, Hiroki Moriyama, Yasuo Hirata, Hiroshi Ishii, Yoshinao Oaki

Publication number: 20020188174Abstract: 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: ApplicationFiled: June 24, 2002Publication date: December 12, 2002Applicant: Olympus Optical Co., Ltd.Inventors: Chieko Aizawa, Akira Taniguchi, Jun Hasegawa, Katsuyoshi Sasagawa, Seiki Toriyama, Takayasu Miyagi, Tsugio Okazaki, Hiroki Moriyama, Yasuo Hirata, Hiroshi Ishii, Yoshinao Oaki

Patent number: 5860913Abstract: In an endoscope of the present invention, while a cover indicator on a distal cover is aligned with a scope indicator on a main distal part, the distal cover is put on the main distal part in an axial direction at a certain insertion angle. Thereafter, the distal cover is rotated while being thrust in the axial direction. The stoppage of a locking convex part of a hook of the main distal part by a claw of a reinforcement member is released, and the locking convex part of the hook is positioned in a locking ditch of the reinforcement member. The head of the hook is constrained to move in the axial direction by means of a main distal cover that is an elastic member and the claw. The locking convex part is then fitted into the locking ditch reliably. Consequently, the distal cover can be fixed to the main distal part readily, freely detachably, and reliably with high positioning precision.Type: GrantFiled: April 29, 1997Date of Patent: January 19, 1999Assignee: Olympus Optical Co., Ltd.Inventors: Koji Yamaya, Tatsuya Furukawa, Takahiro Kishi, Tsugio Okazaki, Haruhiko Kaiya, Hisao Yabe, Tsutomu Ishiguro

Patent number: 4777524Abstract: In an endoscope having an insertion section and a control section, a distal-end unit is provided at the distal end portion of the insertion section. An objective optical system, which includes a moving lens held by a lens frame, and a solid-state image sensing unit for converting an optical image, formed by the objective optical system, into an electrical signal, are disposed inside the distal-end unit. A transmission member which serves to transmit the electrical signal from the image sensing unit, is connected to the image sensing unit. The distal end portion of a coupling member is connected to the lens frame, and its proximal end portion extends through the insertion section into the control section. A shift-control mechanism for controlling the movement of the moving lens is coupled to the proximal end portion of the coupling member.Type: GrantFiled: July 31, 1987Date of Patent: October 11, 1988Assignee: Olympus Optical Co., Ltd.Inventors: Shigeru Nakajima, Tsugio Okazaki
