Patent number: 6846286Abstract: An endoscope system is provided, including an endoscope having a flexible inserting tube to be inserted into a human body and a plurality of bending sensors distributed over the flexible inserting tube along the longitudinal direction thereof. Each of the bending sensors detects the local bending state of the flexible inserting tube at the location the bending sensor are provided. A computer adapted to receive data on the local bending state from each of the plurality of bending sensors is also provided. The computer generates a graphical image representing the geometrical configuration of the flexible inserting tube from the data on the local bending states. A monitor connected to the computer to display the graphical image generated by the computer.Type: GrantFiled: May 21, 2002Date of Patent: January 25, 2005Assignees: PENTAX Corporation, The Jikei University School of MedicineInventors: Naoki Suzuki, Kazuki Sumiyama, Naoshi Koizumi, Akira Sugiyama, Tetsuya Tarumoto, Toshiyuki Hashiyama, Motoko Kawamura, Takayuki Enomoto, Minoru Matsushita, Tetsuya Nakamura, Kenichi Ohara, Satoshi Takami

Patent number: 6488632Abstract: An ultrasonic endoscope has a bending portion, an ultrasonic probe, and a flexible circuit board. The bending portion, connected to the point of a flexible tube, bends by remote control. The ultrasonic probe has a plurality of ultrasonic wave vibrators, which are arranged circumferentially, and send ultrasonic waves radially and receive echoes of the ultrasonic waves. The flexible circuit board, which transmits signals associated with the ultrasonic waves and the echoes, is constructed of a plurality of flexible circuit board strips in the bending portion so as to allow a bending motion. The plurality of ultrasonic wave coaxial lines, which are provided in the flexible tube to form an ultrasonic wave coaxial cable and are connected to the plurality of flexible circuit board strips, are loose and flexible in a given range.Type: GrantFiled: November 14, 2001Date of Patent: December 3, 2002Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Kenichi Ohara, Toshiyuki Hashiyama

Patent number: 6488631Abstract: An ultrasonic endoscope has a bending portion, an ultrasonic probe, and a flexible circuit board. The bending portion, connected to the point of a flexible tube, bends along two predetermined bending-directions perpendicular to each other, by remote control. The ultrasonic probe has a plurality of ultrasonic wave vibrators, which are arranged circumferentially, and send ultrasonic waves radially and receive echoes of the ultrasonic waves. The flexible circuit board, which transmits signals associated with the ultrasonic waves and the echoes, is constructed of a plurality of flexible circuit board strips in the bending portion so as to allow a bending motion. The plurality of flexible circuit board strips are arranged such that a bending-resistance to the bending motion occurs symmetrically with respect to a primary central line, corresponding to one of the two bending-directions.Type: GrantFiled: November 14, 2001Date of Patent: December 3, 2002Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Kenichi Ohara, Toshiyuki Hashiyama
