| 20090171160 | ENDOSCOPE MAIN BODY AND ENDOSCOPE - An endoscope main body constituting an endoscope in a state in which an elongated detachable observation optical system is attached to the endoscope main body, and in a proximal end of an insertion section of the endoscope main body, a branch member is disposed. The branch member is provided so that a first extended section and a second extended section are branched from each other and thereby first and second operating sections are separately arranged. Furthermore, the branch member has an opening as an inlet which guides an imaging module in a distal end of the observation optical system to a hard portion of the insertion section. | 07-02-2009 |
| 20090209819 | BENDING SECTION STRUCTURE OF ENDOSCOPE - First stepped portions are provided on both sides of each of two front-side projection portions of a front end portion of a node ring. Second stepped portions are provided on both sides of each of two rear-side projection portions of a rear end portion of the node ring. At a time of bending of a bending section, when two front and rear node rings of a bending tube are rotated to a maximum rotational position, the pivotal angle α between the front and rear node rings is restricted to a predetermined restriction angle that prevents, when the bending section is bend-operated, an outer sheath tube from being bitten between the node rings, by the restriction due to contact between the second stepped portion of the front-side node ring and the first stepped portion of the rear-side node ring. | 08-20-2009 |
| 20090253958 | ENDOSCOPE, CONNECTION METHOD OF BENDING SECTION AND FLEXIBLE SECTION IN ENDOSCOPE, PRODUCTION METHOD OF ENDOSCOPE PROVIDED FOR THIS CONNECTION METHOD, ENDOSCOPE OVERTUBE, CONNECTION METHOD OF BENDING SECTION AND FLEXIBLE SECTION IN ENDOSCOPE OVERTUBE AND PRODUCTION METHOD OF ENDOSCOPE OVERTUBE PROVIDED FOR THIS CONNECTION METHOD - An endoscope includes a bending section formed to be bendable by aligning a plurality of substantially cylindrical node rings and coupling the adjoining node rings to each other to allow them to swivel, a flexible section directly coupled to the bending section by fitting a distal end thereof into a proximal end side node ring arranged on the most proximal end side of the bending section, an operation wire that is inserted into the flexible section and the bending section and operates the bending section, and a wire guide section that guides the operation wire inserted into the flexible section to the bending section in the flexible section. | 10-08-2009 |
| 20090253963 | BENDING PORTION OF MEDICAL INSERTION APPARATUS, AND MANUFACTURING METHOD AND MANUFACTURING APPARATUS THEREOF - A manufacturing method for a bending portion of a medical insertion apparatus includes, preparing a bending tube including cylindrical bending parts coaxially connected to each other and rotatable with respect to each other, preparing a braid tube including liner members made of a thermoplastic resin and forming a netlike shape, covering the braid tube on an outer peripheral portion of the bending tube, pushing-heating of protruding inwardly a part of the braid tube to be pushed into a push-in receiving portion of the bending part and heating the part to soften, and pushing-cooling of cooling the part to set. | 10-08-2009 |
| 20100010309 | ENDOSCOPE BEND TUBE AND ENDOSCOPE INCLUDING THE BEND TUBE - An endoscope bend tube includes a plurality of node rings, wherein contact portions at which neighboring ones of the node rings are pit in contact are provided between the neighboring node rings, and the plurality of node rings are coupled to be pivotable about pivotal center axes which correspond to pivotal centers of the contact portions, the endoscope bend tube includes an operation wire, a coupling wire, and a coupling wire hold portion, wherein in a case where the endoscope bend tube is in a non bent state, lead-out ends of the coupling wire hold portions, which are opposed between a pair of the neighboring node rings, are disposed at such positions that a line segment connecting the lead-out ends is halved by a plane including a center axis in a longitudinal direction of the bend tube and a pivotal center axis of the pair of the node rings. | 01-14-2010 |
| 20100056868 | ENDOSCOPE BENDING PORTION - An endoscope bending portion includes bending parts coaxially arranged in a line and each of which includes a cylindrical portion, one bending part of both bending parts adjacent to each other includes a protruding portion integrated with the cylindrical portion and extended in a radial direction of the cylindrical portion, the other bending part of both the bending parts adjacent to each other includes a receiving portion integrated with the cylindrical portion and into which the protruding portion is inserted so as to be rotatable about a longitudinal axis of the protruding portion, and each of the bending parts includes a discontinuous portion extended so as to cross a peripheral direction of the cylindrical portion in the cylindrical portion and joined or unjoined. | 03-04-2010 |
| 20100217082 | COVERED-TYPE ENDOSCOPE, COVER-ADAPTED ENDOSCOPE AND ENDOSCOPE-COVER - A covered-type endoscope includes an endoscope-cover and a cover-adapted endoscope to be inserted into the endoscope-cover. The endoscope-cover includes a tube and a cover-bending portion with a plurality of longitudinally joined cover-joint pieces. The cover-adapted endoscope includes a bending portion with a plurality of longitudinally joined joint pieces. The bending portion includes a guide portion which guides the tube in the longitudinal direction of the bending portion and cooperates with the cover-bending portion of the endoscope-cover to provide a tube placement chamber between the guide portion and the cover-bending portion of the endoscope-cover so that a conduit for the tube is maintained. The tube is flexible to bend in accordance with the bending of the cover-bending portion and the bending portion. | 08-26-2010 |
| 20110030194 | ENDOSCOPIC INSERTION PORTION AND MANUFACTURING METHOD THEREOF - A method of manufacturing an endoscopic insertion portion with high manufacturing efficiency is provided. The endoscopic insertion portion includes a plurality of bending parts provided side by side with each other, a protruding portion provided in one of each two adjacent ones of the bending parts, and a receiving portion provided in the other of each two adjacent ones of the bending parts and into which the protruding portion is inserted rotatably. The method includes forming, in at least one plate material, a first bending part preparation portion for the formation of the one bending part and a second bending part preparation portion for the formation of the other bending part, connecting the first bending part preparation portion and the second bending part preparation portion by press processing, and forming the first and second bending part preparation portion into a cylindrical shape by press processing. | 02-10-2011 |
