ABSTRACT:
A calculus crushing apparatus includes a flexible sheath to be inserted into the body cavity. An operating wire is slidably inserted into the sheath, and a basket for seizing and crushing the calculus is coupled to the distal end of the wire. The sheath has a first sheath having a predetermined strength and a second sheath which is weaker but more flexible than the first sheath. The first sheath is movably inserted into the second sheath. The flexible sheath is inserted into the body cavity while the second sheath projects sufficiently beyond the distal end of the first sheath. After the first sheath is moved to a position where the distal end of the first sheath extends beyond that of the second sheath, the operation wire is pulled to retract the basket, thereby crushing the calculus seized by the basket.
