Prior Art FIG. 3 is a side sectional view for explaining an example of a conventional optical fiber tip holder of a laser probe, and in the figure, 1 is a core portion 1a (including a cladding layer).
2 is a holder for holding the tip of the optical fiber 1, and the holder 2 is used with the A side connected to the laser light source side and the B side connected to the tip tip side. be done. This holder is
a first inner diameter part consisting of a single member and having an inner diameter equal to the outer diameter of the optical fiber 1;
and a second inner diameter part smaller than the diameter of the core part and larger than the diameter of the core part, and as shown in the figure, the coating layer at the tip part has a length corresponding to the length of the second inner diameter part. The cut optical fiber 1 is inserted into the optical fiber holder 2 and fixed therein for use. In the above-mentioned holder, when in use, for example, if a force is applied to the optical fiber 1 in the direction of arrow C, the tip core of the optical fiber 1 moves in the direction of arrow D, and the optical fiber 1 is moved in the direction of arrow D. There was a drawback that the laser beam propagated through the laser beam was directed in an unexpected direction, making it impossible to irradiate it in a desired direction.

Purpose The present invention was made in view of the above-mentioned circumstances, and is particularly aimed at improving the optical fiber tip of a probe so that the laser beam emitted from the tip of the optical fiber does not go in an unexpected direction while the probe is in use. It was made for the purpose of providing a part holder.

Configuration Fig. 1 is a perspective view showing an embodiment of the optical fiber tip holder of the laser probe according to the present invention, Fig. 2A is a side sectional view, and Fig. 2B is B of Fig. 2A.
This is a view seen from the direction of the -B line, and in the figure, the same reference numerals as in the case of FIG. 3 are given to parts that have the same function as the holder in FIG. 3. Therefore, in the present invention, the core portion 1 of the optical fiber 1 is attached to the distal end portion following the second inner diameter portion of the conventional holder shown in FIG.
a (including the cladding layer);
A slot 2a is provided on the inner diameter part of the inner diameter part, and a screw 2b is provided on the outer peripheral part from the third inner diameter part to the second inner diameter part. , the tip of the optical fiber 1 can be fixed by the third inner diameter part, and the third inner diameter part of the optical fiber 1 can be fixed during use of the chip.
Even if the force described with reference to the figures is applied, the tip of the optical fiber 1 does not move, and the laser beam propagated within the optical fiber 1 can always be emitted in a desired direction. In addition, a slotted groove 2a is provided in this third inner diameter part, and air or distilled water, etc. flows through this slotted part.
The flow of air, distilled water, etc. does not deteriorate in the third inner diameter portion.

Effects As is clear from the above explanation, according to the present invention, the tip of the optical fiber can be securely fixed, and the direction of the laser beam emitted from the tip of the optical fiber can be prevented from changing during use. It is possible to provide an optical fiber tip holder for a laser probe that does not cause any problems.
