Catheter tip rotation angle measuring device, a driving method of the catheter tip rotation angle measuring device and the catheter tip rotation angle measurement program

Catheter tip rotation angle measuring device has a first cylindrical shape penetrating up to the second hole 1011 from the hole 1010, which is the other end which is one end of the distal end of the catheter 10, first from the first hole 2 a movement restricting portion 101 for restricting the movement of the catheter in the insertion direction by passing the catheter to hole, the first rotational angle measurement unit 102 for measuring a first rotation angle is a rotation angle of the catheter in the first bore, catheterization to measure the second rotation angle measuring section 103 for measuring a second rotational angle that is the rotational angle of the catheter in the second hole, the catheter insertion length is a length from the first hole to the tip of the catheter the length measuring unit 104, the angle difference between the first rotation angle and the second rotation angle, using the distance between the catheter insertion length, and the first hole and the second hole, and calculates the rotation angle of the tip of the catheter catheter tip times It comprises an angular calculation unit 105, a.
