Patent number: 8702700Abstract: A surgical treatment device which is used together with an endoscope, includes a sheath, a treatment portion which is arranged at the distal end portion of the sheath and includes first to third electrodes configured to treat a living tissue by using electrical energy, an operation portion which is arranged at a proximal end portion of the sheath and which is configured to operate the treatment portion, and a switching portion which is configured to switch between a first mode in which a treatment is given by using the first electrode and at least one of the second and third electrodes in the treatment portion and a second mode in which a treatment is given by using the second and third electrodes.Type: GrantFiled: October 29, 2012Date of Patent: April 22, 2014Assignees: Terumo Cardiovascular Systems Corporation, Olympus Medical Systems CorporationInventors: Seiji Maeda, Hideyuki Kasahara, Akihito Kano, Hiroaki Ichikawa, Susumu Komagata, Randal J. Kadykowski

Patent number: 8273087Abstract: An ultrasonic surgical instrument has an ultrasonic transducer unit having an ultrasonic transducer for producing ultrasonic vibration, a transmission member which connects the ultrasonic transducer in the proximal end side, and transmits the ultrasonic vibration produced by the ultrasonic transducer from the proximal end side to the distal end side, a sheath, in which the transmission member is inserted, having an open part on one side of the distal end side, and a treatment portion which is provided at the distal end of the transmission member, and exposed to the open part for carrying out a surgical treatment on an object part by the ultrasonic vibration transmitted from the transmission member. The ultrasonic surgical instrument cuts or shaves hard tissues.Type: GrantFiled: April 6, 2009Date of Patent: September 25, 2012Assignee: Olympus Medical Systems Corp.Inventors: Kenichi Kimura, Susumu Komagata, Hideto Yoshimine, Manabu Ishikawa

Patent number: 8236018Abstract: An ultrasonic surgical instrument comprises an ultrasonic transducer producing ultrasonic vibration, a transmission member transmitted ultrasonic vibration from the proximal end to the distal end, a sheath in which the transmission member is inserted, a procedural unit provided to the distal end of the transmission member so that it projects from the distal end of the sheath, and treating a surgical target portion using ultrasonic vibration, a procedural unit main body provided in the procedural unit, a procedural member provided in the sheath so that it projects from the distal end of the sheath to treat the surgical target portion, and a procedural member main body provided at the distal end of the procedural member. In the ultrasonic surgical instrument, the procedural member main body overlaps with the procedural unit main body, and thereby, the procedural member main body and the procedural unit main body treat the portion.Type: GrantFiled: April 6, 2009Date of Patent: August 7, 2012Assignee: Olympus Medical Systems Corp.Inventors: Hideto Yoshimine, Manabu Ishikawa, Kenichi Kimura, Susumu Komagata

Patent number: 8048100Abstract: A blunt dissector for separating a blood vessel from surrounding tissues in a body comprises a longitudinal rod having a proximal end, a distal end, and an internal passage for conducting insufflation gas between the proximal and distal ends. An interior sleeve is mounted within the longitudinal rod for receiving an endoscope at the proximal end. A transparent tip is mounted to the distal end of the longitudinal rod. A handle is mounted to the proximal end of the longitudinal rod. The longitudinal rod has an outer surface along substantially all of the longitudinal rod between the proximal and distal ends consisting essentially of a fluoropolymer.Type: GrantFiled: June 10, 2008Date of Patent: November 1, 2011Assignee: Terumo Cardiovascular Systems, Corp.Inventors: Randal J. Kadykowski, Lyne M. Charron-Keller, Seiji Maeda, Susumu Komagata, Hideyuki Kasahara, Akihito Kano, Ken Yamatani
