PROBLEM TO BE SOLVED: To provide a medical instrument capable of surely detecting a part to be treated and safely applying radiation thereto. SOLUTION: This medical instrument has a core wire 1 around which a coil 3 consisting of radiative material is attached. A first coil 4 of radiation non-transmissible material on the side of base end and a second coil 5 of radiation non-transmissible type hold and position the coil 3. The coil 3 can be surely positioned around the wire 1 and thereby accurate observation by an X-ray inspection can be made. |
