PURPOSE: To insert the insertion tube of a small X-ray tube to a prescribed part with high rectilinearity and certainty by fixing the small X-ray tube on the prescribed part of the human body with a supporting member, inserting a sheath to the human body by reinforcing by the insertion of a solid bar and inserting the insertion tube to the sheath after extracting the solid bar. CONSTITUTION: Reinforcement is performed by inserting the solid bar to the inside of the sheath 13. The sheath 13 set in such a state is inserted to a living body 5 so as to drive in the terminal part of the solid bar. The tip part of the sheath 13 is suspended by bringing it into contact with a defective part 19, or inserting it to the inside, thence, the solid bar is extracted from the sheath 13, and only the sheath 13 is left in the living body 5. Thence, the small X-ray tube 11 is fixed on the head of the living body 5 with the supporting member 12. Thence, the insertion tube 20 extending from the small X-ray tube 11 in the longitudinal direction of the sheath 13 is fixed by inserting it so as to make the longitudinal direction coincide. |
