Title (EN) SPIRAL UNIT AND GUIDE DEVICE
(FR) UNITÉ SPIRALÉE ET DISPOSITIF DE GUIDAGE
(JA) スパイラルユニット及び導入装置
Abstract:
(EN) This spiral unit is provided with: a tube body having a spiral fin on the outer peripheral surface thereof; a cylindrical tapered unit which is provided along the longitudinal axis, which has a proximal part near to and a distal part far from the tube body, which contracts in circumference from the proximal part towards the distal part along the longitudinal axis, and which at the distal part exercises a contracting force on the outer peripheral surface of an insertion unit in the range permitting sliding in the direction around the longitudinal axis; and a contraction limiting body which is arranged so as to be detachable from the tapered unit, which limits contraction of the inner diameter of the tapered unit by maintaining a state in which the inner diameter of the tapered unit is expanded to allow insertion of the insertion unit in the tapered unit, and which, by the removal of said contraction limiting body occurring accompanying insertion the insertion part into the tapered unit, exercises on the distal part of the tapered unit a contraction force in the range permitting sliding in the direction around the longitudinal axis relative to the outer peripheral surface of the insertion unit.
(FR) La présente invention concerne une unité spiralée qui comprend : un corps tubulaire ayant une ailette spiralée sur sa surface périphérique externe; une unité conique cylindrique qui est disposée le long d'un axe longitudinal, qui a une partie proximale à proximité du corps tubulaire et une partie distale distante, qui se contracte en circonférence de la partie proximale vers la partie distale le long de l'axe longitudinal, qui exerce au niveau de la partie distale une force de contraction sur la surface périphérique externe d'une unité d'insertion dans la plage permettant le coulissement dans la direction autour de l'axe longitudinal; et un corps de limitation de contraction qui est agencé de manière à être détachable de l'unité conique, qui limite la contraction du diamètre interne de l'unité conique en maintenant un état dans lequel le diamètre interne de l'unité conique est expansé pour permettre l'insertion de l'unité d'insertion dans l'unité conique, et qui, par le retrait dudit corps de limitation de contraction survenant concomitamment avec l'insertion de la partie d'insertion dans l'unité conique, exerce sur la partie distale de l'unité conique une force de contraction dans la plage permettant le coulissement dans la direction autour de l'axe longitudinal par rapport à la surface périphérique externe de l'unité d'insertion.
(JA)  スパイラルユニットは、その外周面に螺旋フィンを有するチューブ体と、長手軸に沿って設けられ、前記チューブ体に近接する近位及び離隔する遠位を有し、その外周が前記長手軸に沿って前記近位よりも前記遠位の方が前記長手軸に向かって縮径され、前記遠位で挿入部の外周面に対して前記長手軸の軸回り方向に摺動可能な範囲で縮径力を発揮させる筒状のテーパ部と、前記テーパ部に対して取り外し可能に配設され、前記テーパ部に前記挿入部が挿通されるのを許容するように前記テーパ部の内径を拡径させた状態を保持して前記テーパ部の内径が縮径するのを規制し、前記テーパ部に前記挿入部が挿通されるのに伴って取り外されることによって、前記テーパ部に前記遠位で前記挿入部の外周面に対して前記長手軸の軸回り方向に摺動可能な範囲で縮径力を発揮させる縮径規制体とを有する。
