SHAPE LOCKABLE APPARATUS FOR FLEXIBLE TUBES

摘要

PURPOSE: A shape locking device of a flexible tube is provided to improve operability of the flexible tube by accurately controlling movement of the leading end through an interlocking structure of joint rings. CONSTITUTION: A flexible tube(10) has a bore(12), a first end(14), and a second end(16). A plurality of joint rings(20) is installed at the outer side of the flexible tube along a longitudinal direction of the flexible tube. A sleeve(22) of the joint ring has a bore (22a), a first end(22b), and a second end(22c). A pair of arms(30) is extended from the second end of the sleeve in order to be parallel. A connection unit(40) is composed of a locking bar(42), a connecting rod(44), and a locking wire(48).
