PURPOSE: To simplify and downsize a driving mechanism for a treating member by installing a treating part for treating a part in a vagina to be treated, at the tip of a treating tool body inserted into the vagina and a driving part for driving the treating part.
CONSTITUTION: When an operating switch 25 for a holding body is turned ON, a heating coil 22 conducts and generates heat, and the fluid paraffine introduced inside a bellows 21 is vaporized and expanded, and the bellows 21 extends in the axial direction. Accordingly, a shifting member 6 having cups 9 and 9 installed advances. When an operating switch 18 for the holding body is turned ON, a heating coil 15 on the periphery of a driving body 13 carries current and generates heat, and heats the driving body 13. Since the driving body 13 is expanded and elongated in the axial direction, a pair of cups 9 and 9 are opened through a pantagraph mechanism. When the switch 18 is turned OFF, the driving body 13 contracts to close the cups 9 and 9. Accordingly, the need of arranging an operating wire having a thickness for transmitting a mechanical driving operation force inside a sheath is obviated, and diameter of the sheath can be reduced.
