When inserting the protective pipe 4 (mm) into the through hole 7 of the grip tube 1, as shown in FIG. If 14' and 14' are not aligned, a part of the ball 8 will protrude into the through hole 7 due to the inner peripheral surface of the ring 10, and this protrusion will prevent the optical axis of the small-diameter protection pipe 4 from aligning with the rod member. It becomes possible.

構成となる。Further, in the above embodiment, since the diameter of the protective pipe 4 is of two types, small diameter and large diameter, the number of pit holes 10a provided in the ring 10 is equal to the number of balls 8, but When the number of types of protective pipes 4 to be used increases to two or more, it becomes necessary to separately provide pit holes 10a with different depths in order to adjust the amount of protrusion of the ball 8 into the through hole 7. Of course. Furthermore, the non-contact type laser scalpel device also has the same configuration as the above embodiment except that what is fixed to the fixture 2 is a condenser lens instead of a rod member.

保できる等、その効果は、極めて大きい。f. Effects As is clear from the above, even if there are protection pipes of various diameters, the present invention can achieve the desired effect by predetermining the depth of the ball pit according to the diameter of each protection pipe. The optical axis of the transmission fiber inserted into the protection pipe can be easily aligned with the optical axis of the rod member or condensing lens, and the protection pipe into which the transmission fiber is inserted has flexibility. However, since the optical axis is aligned near the rod member or condensing lens, there is no need to worry about axis misalignment, and the structure is simple. The effects are extremely large, such as lower manufacturing costs and improved performance.
