ABSTRACT:
A flexible sheath for an endoscope has a flexible hollow cylindrical tube and a helical coil spring which is inserted into the flexible hollow cylindrical tube. One end of the spring is made engageable with one end of the hollow cylindrical tube to adjust the flexibility of the flexible sheath. A mechanism for compressing the helical coil spring is provided at the other end of the hollow cylindrical tube. The mechanism comprises a spring-compressing member disposed at the other end of the helical coil spring and an actuating member for reciprocating the spring-compressing member between a position in which the spring-compressing member compresses the helical coil spring and a position in which the spring-compressing member is axially removed from the other end of the helical coil spring. The magnitude of a force axially applied to the helical coil spring is controlled in accordance with the extent to which the spring-compressing member is moved toward the helical coil spring by the actuating member, thereby adjusting the flexibility of the flexible sheath.
