PROBLEM TO BE SOLVED: To provide a multi-purpose tube capable of obtaining a clear MRI image or the like necessary for an operation such as a tumor extirpation. SOLUTION: A single or a plurality of side holes 3 are perforated at a tube wall near a distal end of the tube 1 made of a synthetic resin in which a cannonball-like closing member 2 is fixed to the distal end. Then, polyethylene glycol or a dimethylsilicone oil is poured directly or via a small member, a strip-like material or the like in the tube wall arriving from the vicinity of the holes 3 to a base end of the tube 1 and embedded. If an X-ray impermeable line is provided together at the tube wall, this can be also used in the case of a CT image or a simple X-ray photographed image. |
