Publication number: 20100125164Abstract: An improved system for attaching devices to the distal end of endoscopic instruments is described. An attachment adapter comprises a distal stop, such as a complete or partial loop or cylinder, which limits the penetration of an endoscope into the adapter. The adapter has at least one flange protruding proximally along the endoscope. The adapter is secured on the endoscope by a securing means, which compresses the flange or flanges sufficiently to provide a friction fit. The flexibility of the inventive adapter system allows the adapter to work reliably with endoscopes that are used, damaged or repaired. The adapter may further provide a slit or window allowing viewing of the vessel wall by a lens on an endoscope, thereby improving the operator's ability to understand the location of the endoscope during operation. The adapter may carry any of a variety of devices, including devices for closing a surgical incision, or treating or manipulating tissue.Type: ApplicationFiled: November 18, 2009Publication date: May 20, 2010Inventor: Denis LaBombard

Publication number: 20100121145Abstract: Measured locations of position sensors on a steerable medical device are used to determine the insertion depth of the steerable medical device with respect to a foundation point, which is initialized by an operator. The insertion depth, in turn, is used to determine the state of each segment that has passed the foundation point, i.e., is distal to the foundation point.Type: ApplicationFiled: November 6, 2009Publication date: May 13, 2010Inventor: Caitlin Donhowe

Publication number: 20100121146Abstract: A scanning endoscope comprising a first transmitter, an actuator, a first mirror, and a second mirror, is provided. The first transmitter emits a beam of radiant light from an emission end. The actuator moves the emission end along a spiral course. The first mirror is arranged from the emission end toward a first direction. The first mirror comprises a first reflection surface around the first direction. The first reflection surface reflects the radiant light emitted from the first transmitter. The second mirror is arranged around the first reflection surface. The second mirror comprises a second reflection surface. The second reflection surface reflects the radiant light reflected by the first mirror in a direction that includes the first direction as a positive vector toward any points on the first line.Type: ApplicationFiled: November 9, 2009Publication date: May 13, 2010Applicant: HOYA CORPORATIONInventor: Hideo SUGIMOTO

Patent number: 7713191Abstract: A balloon controller for an endoscope apparatus which enables an operator to correctly and immediately grasp circumstances relating to an abnormal condition at the time of occurrence of the abnormal condition. The balloon controller controls expansion and shrinkage of each of a first balloon attached to an insertion portion of an endoscope and a second balloon attached to an insertion assist implement, by supplying air to the balloon or drawing air from the balloon. Pressure indicating portions on which the values of pressures in the first and second balloons are displayed are provided in a front surface of a main body of the balloon controller. When an abnormal condition occurs, an error code and the pressure values are alternately displayed on the pressure indicating portions.Type: GrantFiled: November 3, 2005Date of Patent: May 11, 2010Assignee: Fujinon CorporationInventors: Tadashi Sekiguchi, Tetsuya Fujikura

Publication number: 20100113876Abstract: An endoscope apparatus including an insertion portion for insertion into a body cavity; an image-acquisition unit disposed at a tip thereof that acquires an image of the inside of the body cavity; an insertion-length measuring unit disposed at a base end of the insertion portion that measures an insertion length of the insertion portion inside the body cavity; a storage unit that stores the image acquired by the image-acquisition unit in association with the insertion length measured by the insertion-length measuring unit; a following decision unit that determines whether insertion movement at the tip follows insertion movement at the base end; and a correcting unit that corrects the insertion length of the insertion portion associated with the acquired image to cancel a change in the insertion length measured in a non-following period on the basis of the result of that determination.Type: ApplicationFiled: March 13, 2008Publication date: May 6, 2010Applicant: OLYMPUS CORPORATIONInventor: Yasushige Ishihara

Publication number: 20100113877Abstract: A medical apparatus having a medical device that is utilized to perform a predetermined medical action, includes an energy supply source including an attachment/detachment portion to/from which the medical device is attached/detached, and supplies energy when the medical device is utilized to perform the predetermined medical action, an energy output adjustment unit which adjusts the energy supplied from the energy supply source to medical action energy suitable for performing the predetermined medical action by using the medical device when the medical device is connected to the attachment/detachment portion, and an energy supply detecting mechanism for detecting a state that the energy supply source has supplied the medical action energy. When the determination mechanism detects a state that the energy supply source has supplied the medical action energy, the energy output from the energy supply source is prevented from being supplied to the medical device.Type: ApplicationFiled: January 11, 2010Publication date: May 6, 2010Inventor: Akira SUZUKI

Patent number: 7706859Abstract: Position detecting elements are disposed in an endoscope insertion portion at predetermined intervals. Even when the endoscope insertion portion is bent, position data representing the detected positions of the elements is used to infer or detect the shape of the insertion portion. A virtual element is disposed between adjoining elements so that a predetermined condition will be met. Position data of the virtual element is used together with the actually detected position data in order to interpolate data for the purpose of detecting the shape of the insertion portion. Consequently, as if a larger number of elements were disposed, the shape of the insertion portion can be detected highly precisely.Type: GrantFiled: August 22, 2003Date of Patent: April 27, 2010Assignee: Olympus CorporationInventors: Chieko Aizawa, Fumiyuki Onoda, Sumihiro Uchimura, Akira Taniguchi
