Abstract
(EN) Provided is a catheter that is easy to handle even while being equipped with parts that can be connected and disconnected. A catheter (1) comprising: a sheath (2) to be inserted into a lumen; a driving shaft (42) for transmitting a mechanical driving force; a hub (31) for moving the driving shaft (42); an outer tube (32) provided on the base end of the sheath (2) and provided with a first connector (372) on the base end; an inner tube (34) that is able to move inside the outer tube (32); a second connector (35), which can be connected to and disconnected from the first connector (372) and is able to accommodate the inner tube (34); a sheath connecting section (33) for connecting the sheath (2) to the outer tube (32); and a protective tube (67), which protrudes past the leading end of the inner tube (34) and accommodates the driving shaft (42) while also being capable of being inserted into the outer tube (32) and the sheath (2) and of being withdrawn from the outer tube (32) together with the hub (31) and the inner tube (34) as a result of disconnecting the second connector (35) from the first connector (372).
(FR) L'invention concerne un cathéter qui est facile à manipuler même en étant équipé de parties qui peuvent être connectées et déconnectées. L'invention concerne un cathéter (1) comprenant : une gaine (2) à insérer dans une lumière; un arbre d'entraînement (42) pour transmettre une force d'entraînement mécanique; une plaque tournante (31) pour déplacer l'arbre d'entraînement (42); un tube externe (32) fourni sur l'extrémité de base de la gaine (2) et pourvu d'un premier connecteur (372) sur l'extrémité de base; un tube interne (34) qui est capable de se déplacer à l'intérieur du tube externe (32); un second connecteur (35), qui peut être connecté à et déconnecté du premier connecteur (372) et est capable de recevoir le tube interne (34); une section de connexion de la gaine (33) pour connecter la gaine (2) au tube externe (32); et un tube protecteur (67) qui fait saillie au-delà du bord avant du tube interne (34) et reçoit l'arbre d'entrainement (42) tout en étant capable d'être inséré dans le tube externe (32) et la gaine (2) et d'être retiré du tube externe (32) conjointement avec la plaque tournante (31) et le tube interne (34) comme résultat de la déconnexion du second connecteur (35) du premier connecteur (372).
(JA)  接続および切り離しが可能な部位を備えつつも、高い操作性を備えたカテーテルを提供する。 管腔内に挿入されるシース(2)と、機械的駆動力を伝達する駆動シャフト(42)と、駆動シャフト(42)を移動させるハブ(31)と、シース(2)の基端側に設けられ、基端部に第1のコネクタ(372)を備える外管(32)と、外管(32)内を移動可能な内管(34)と、第1のコネクタ(372)に対して接続および切り離し可能であるともに、内管(34)を受け入れ可能な第2のコネクタ(35)と、シース(2)および外管(32)を接続するシース接続部(33)と、内管(34)よりも先端側へ向かって突出して駆動シャフト(42)を収容するとともに外管(32)およびシース(2)内へ挿通可能であり、第2のコネクタ(35)を第1のコネクタ(372)から切り離してハブ(31)および内管(34)とともに外管(32)から引き抜くことが可能な保護管(67)と、を有するカテーテル(1)である。
