Patent number: 8271135Abstract: An apparatus for holding a medical device has an arm unit equipped with, for example, a polyarticular arm, which holds the medical device such as endoscope movably in the space. Additionally to a determination unit and a controller, the holding apparatus has an operation unit equipped with a plurality of operation members with which an operator's operation causes the arm unit to be moved spatially. The determination unit determines whether or not operator's operations at the plurality of operation members corresponds to an improper state deviating from a properly operated state in which at least two predetermined operation members have been operated within a predetermined period of time which is set to measure simultaneity for operations. If it is determined that the operation is in the improper state, the controller prohibits the arm unit from moving. As long as the operation is proper, the arm unit can be moved.Type: GrantFiled: October 25, 2010Date of Patent: September 18, 2012Assignee: Olympus CorporationInventors: Keiji Shioda, Satoshi Otsuka, Masaaki Ueda, Kazuhito Nakanishi

Publication number: 20040070822Abstract: Provided is a surgical observational system capable of effectively displaying, in the field of an operating microscope, a real-time image obtained by means of an ultrasonic probe, for example, and a slice image obtained by a preoperative diagnosis on the location of the distal end portion of the probe or a three-dimensional image of an affected region, in association with an actual observational image obtained by means of the microscope. The surgical operation observational system is provided with two monitors in the operating microscope for the observation of the affected region to be operated. Images on the two monitors are alternatively superposed on the optical path of the operating microscope.Type: ApplicationFiled: September 11, 2003Publication date: April 15, 2004Applicant: OLYMPUS OPTICAL CO., LTD.Inventors: Keiji Shioda, Koji Shimomura, Kazuhito Nakanishi, Masakazu Mizoguchi, Masaaki Ueda, Masahiko Kinukawa, Wataru Ohno, Toru Shinmura, Koji Yasunaga, Takashi Fukaya, Masaki Takayama
