| 20120078041 | ENDOSCOPE - An endoscope includes: a distal end opening of a treatment instrument insertion channel opened at a side surface of a distal end portion; a treatment instrument elevator base that is provided at a position facing the distal end opening in the treatment instrument insertion channel and leads a distal end of a treatment instrument protruding from the distal end opening, to a desired position; a first wall portion along the insertion direction of the distal end opening; and a second wall portion at a proximal end side of the insertion direction of the distal end opening and provided with a groove in which a part of the treatment instrument elevator base is fitted when the treatment instrument elevator base is raised, and as the treatment instrument elevator base is raised, a guide wire protruding from the distal end opening is releasably engaged by contacting the treatment instrument elevator base, the first wall portion, and a surface constituting the groove of the second wall portion. | 03-29-2012 |
| 20080214890 | Therapeutic method and therapeutic system used with steps for approaching to lesion using overtube - A therapeutic system is provided, which is preferable to a treatment of pancreatic duct and biliary duct for Roux-en-Y gastrectomy patient. The therapeutic system is provided with a catheter equipped with an imaging device outputting a signal in reply to imaging, an overtube to be inserted into inside a patient, and a display displaying images based on the signal outputted from the imaging device. The overtube has an inserting channel into which the catheter is inserted, a therapeutic instrument channel into which a therapeutic instrument is inserted, an elevating base formed in an opening located at a distal end of, at least, the therapeutic-instrument channel, and an operation device to operate the elevating base. The elevating base is formed to allow a distal end portion of the therapeutic instrument to be mounted on the elevating base to elevate the distal end portion. | 09-04-2008 |
| 20100069712 | MOTHER-BABY ENDOSCOPE - A mother-baby endoscope includes: a lateral-view mother endoscope housing a treatment instrument raising stand in a distal end portion and including a treatment instrument insertion channel disposed in an insertion portion and opening toward the treatment instrument raising stand; and a baby endoscope including an insertion portion having a bending portion disposed on a distal end side, the insertion portion being inserted into the treatment instrument insertion channel of the mother endoscope and guided into a body cavity for observing or treating a region to be inspected. When the insertion portion of the baby endoscope is protruded by approximately 20 millimeters from an observation window of the mother endoscope in an observation direction, a proximal end surface of the bending portion of the baby endoscope is set to be located on a more proximal end side than an opening portion of the treatment instrument insertion channel. | 03-18-2010 |
| 20110077461 | ENDOSCOPE AND INSTRUMENT LIFTING OPERATION DEVICE FOR THE SAME - An instrument lifting operation device including: an operation wire drawing mechanism configured to draw an proximal end of an operation wire connected to an instrument lifting piece; and a braking mechanism configured to restrict movement of the operation wire toward the tip side, wherein the braking mechanism includes: a fixed wall; and a spring arranged to be able to rotate about an axis together with an instrument lifting operation member in a state where the spring is elastically pressed against an inner circumferential surface of the fixed wall. When the instrument lifting operation member is operated to rotate about the axis, the wire coupling member rotates about the axis and the operation wire moves forward and backward in a state where the spring contacts and slides on the inner circumferential surface of the fixed wall to generate frictional resistance at a contacting part. | 03-31-2011 |
| 20110184234 | DEVICE AND METHOD FOR MINIMALLY INVASIVE SPINAL INTERVENTION - The invention proposes a device for minimally invasive intervention in the skeletal region, in particular on the spinal column, having at least the following two elements:
