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.
