摘要： An endoscope capable of being autoclaved in accordance with the present invention includes an insertion unit, an internal endoscope space, and contents. The insertion unit has a soft member, which is made of a soft polymeric material, as at least part of a casing thereof. The internal endoscope space includes the internal space of the insertion unit that is formed at a first sealing level at which the internal space is sealed in a watertight manner relative to an outside. The contents include at least one hermetically sealed unit composed of a plurality of airtight partition members and formed at a second sealing level higher than the first sealing level by joining the meeting portions of the airtight partition members using an airtight joining material. All or part of the airtight partition members is stowed in the internal endoscope space. Even when high-pressure high-temperature steam permeates through the soft member of the insertion unit which is made of a polymeric material, and invades into the internal endoscope space formed at the first sealing level, the high-pressure high-temperature steam will be hindered from invading into the hermetically sealed unit included in the contents and formed at the second sealing level.

摘要： An endoscope includes an operating portion placed outside a living body, an insertion portion having a proximal end portion coupled to the operating portion, a distal end portion inserted in the living body, and an instrument insertion channel extending through the insertion portion, a raising mechanism having an operation wire and designed to direct the distal end portion of an instrument, caused to extend through the channel, to a predetermined position, and an operation means for operating the operation wire. The endoscope includes a distal end body portion arranged at the distal end portion of the insertion portion and incorporating an observation means for observing the interior of the living body, a support member for forming at least a portion of the outer surface of the distal end portion. The support member is detachable from the distal end body portion. The endoscope further includes a raising base which is supported on the support member such that the angle at which the raising base is arranged can be adjusted. The angle of the raising base is adjusted by the operation wire. The operation wire is detachable from the operation means.

摘要： With a first endoscope inserted through an overtube, the overtube is orally inserted into an object being examined, and a distal end portion of an insertion tube of the first endoscope is made to advance, within the object, from a jejunum via a jejunum-to-jejunum anastomosed portion and a jejunum-anastomosed bent portion so that the distal end portion is located adjacently to a Vater's papilla of a duodenum. The overtube is then sent to a position which is adjacent to the Vater's papilla along the insertion tube of the first endoscope. After this, the first endoscope is pulled from the overtube. A second endoscope is then inserted into the overtube to make a distal end portion of its insertion tube protrude from the distal end of the overtube and is located adjacently to the Vater's papilla. The second endoscope thus-approached is used to treat the Vater's papilla and the tissue therearound.

摘要： An endoscope system comprises an endoscope, medical instrument, operating unit, first and second drive units, and control unit. The endoscope comprises a flexible insertion tube being inserted into an object being examined. The medical instrument is partially inserted into the object through the insertion tube and the operating unit is used for commanding the medical instrument to operate. The first drive unit drives the medical instrument to enable an inserting and pulling-out operation of the medical instrument with the object through the insertion tube. The second drive unit drives the medical instrument to enable the medical instrument to perform a therapeutic operation in the object. The control unit controls drive of the first and second driving devices depending on both an operated state of the operating device and an interference state caused between the medical instrument and the insertion tube when the instrument is actually used.

摘要： An endoscope treatment system comprises plural types of treatment instruments, plural types of adapters, and an advancing and retracting device. The treatment instruments include treatment instrument inserting sections which can be inserted into a treatment instrument channel of an endoscope. The treatment instruments have different outer diameter dimensions depending on their types. The adapters are attached to the treatment instrument inserting sections having different outer diameter dimensions to form surface to be pressed which has a fixed dimension for the treatment instruments. The adapters respectively have a through-hole corresponding to each diameter dimension of the treatment instrument inserting sections. The advancing and retracting device includes a pair of rollers separated by a distance corresponding to the surface to be pressed of a fixed dimension. The rollers hold the surface to be pressed of the adapter attached to the treatment instrument inserting section under a predetermined pressure. A rotation of the rollers with the adapter being held between the rollers causes the adapter to advance and retract.

摘要： An apparatus is provided which assists operations required for a medical instrument. A tubular portion and a therapeutic member of the instrument are inserted through a channel of an insertion tube of an endoscope. In the apparatus, a first drive unit enables the therapeutic member to perform the desired therapeutic operations responsively to a first command signal and a second drive unit enables the tubular portion inserted in the channel to convey responsively to a second command signal. An input device is provided at which two kinds of commands are allowed to be inputted command by command. The two kinds of commands allow the therapeutic member and the tubular portion to be driven in parallel with each other. A controller provides the first and second drive units with the first and second command signals, respectively, in accordance with the two kinds of commands.
