Patent number: 8870778Abstract: An intraluminal endoscope inserting method according to the present invention is a method of forming a first opening in a wall of a first luminal organ while observing optical and ultrasonic images formed by an ultrasonic endoscope inserted into a first luminal organ through a natural opening, forming a second opening in a wall of a desired second luminal organ adjacent to the first luminal organ through an abdominal cavity space from the first opening, leading the ultrasonic endoscope into a second luminal organ from a second opening and performing observation and treatment, and after the treatment and the like, stitching the openings. This makes it possible to insert the endoscope with a skill same as that required for a normal endoscope test and makes it easy to insert the endoscope even into luminal organs irregularly connected to with one another in a body cavity.Type: GrantFiled: December 24, 2007Date of Patent: October 28, 2014Assignee: Olympus Medical Systems Corp.Inventors: Shinichi Tsutaki, Hidemichi Aoki, Takeharu Nakazato, Kosuke Motai, Toshihiro Shizuka

Publication number: 20120265057Abstract: When an ultrasound endoscope arrives at an objective area, a puncture needle is located in a scan area of a first ultrasound image. Thereby, an image of the puncture needle is delineated on the first ultrasound image. Furthermore, an ultrasound probe is inserted into the puncture needle and an ultrasound transducer of the ultrasound probe is arranged in the objective area through the puncture needle. Then, the ultrasound probe is driven and a second ultrasound image is delineated. Detailed observation inside the objective area in which the puncture needle is punctured is possible with the second ultrasound image.Type: ApplicationFiled: June 14, 2012Publication date: October 18, 2012Applicant: OLYMPUS MEDICAL SYSTEMS CORP.Inventors: Kenichi NISHINA, Masatoshi SATO, Takeharu NAKAZATO, Sunao SATO, Takuya IMAHASHI, Shinichi TSUTAKI

Patent number: 8211007Abstract: A treatment instrument for endoscope of the present invention includes a puncture needle having a barb. A lymph node removing method of the present invention includes: an insertion step, wherein an endoscope has an insertable insertion portion which is inserted into an esophagus or a trachea being a lumen inside the body of a subject; the step of inserting a distal end portion arranged at the tip of the insertion portion of the endoscope into the lumen; a confirmation step of confirming the position of a mediastinal lymph node by performing ultrasound scanning using an ultrasound transducer arranged at the distal end portion; an anchoring step of placing an anchoring device which has been inserted through a channel inside the insertion portion of the endoscope, on the mediastinal lymph node by performing the ultrasound scanning; a incision step of cutting a wall of the lumen to make a fistula; and a drawing-in step of drawing the mediastinal lymph node into the lumen with the anchoring device.Type: GrantFiled: August 25, 2011Date of Patent: July 3, 2012Assignee: Olympus Medical Systems Corp.Inventors: Kenichi Nishina, Shinichi Tsutaki, Takeharu Nakazato, Tetsuya Yamamoto
