<p><P>PROBLEM TO BE SOLVED: To provide an correction tool for a crotch part, comprising an easily operable and effectively usable elastic band part and a fixed orthodontic tool member. <P>SOLUTION: An correction tool part 8 comprises a pelvis ring 10, a thigh bone member 12, a knee member 14, and a joining means 16 with a hinge 20. The joining means 16 joins the pelvis ring 10 and the knee member 14. The thigh bone member 12 is joined to the joining means 16 between the pelvis ring 10 and the knee member 14 or a component member of the joining means 16. Further the hinge 20 allows the thigh part to bend. Relating to the correction tool, the hinge 20 has a plurality of hinge axes and those axes all together limit a movement plane for the knee member 14 and the thigh bone member 20 to move relative to the pelvis ring 10. At least a part of the joining means 16 is made of a spring like material and bendable to a direction toward the thigh part and a direction to leave the thigh part. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
