PURPOSE:To provide a laser probe that can move back and forth smoothly without it's tip broken by giving a regulation member which adjusts so that the tip is placed in position inside a protective tube. CONSTITUTION:A J-shaped hook 16a is formed at the head of an artificial sapphire chip 16. An almost cylindrical-shaped regulation member 24 is rotatablly attached to the head of a hard pipe 14 using a rolling compaction method with the regulation member 24 being in eccentric radius condition. When the artificial sapphire chip is screwed and secured to the hard pipe, the rotational stop position of this regulation member can be adjusted so that it's eccentric direction aligns with the bent direction of the J-shaped hook. Since the hard pipe inserted into trocar 18 is placed in an eccentric radius position by the regulation member, the J shaped hook is placed apart from the inner wall of trocar. |
