る。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint reflection mirror used for refracting laser light in a joint of a multi-joint manipulator type laser surgical apparatus. FIG. 2 is a cross-sectional view showing a conventional example of this type of reflection mirror for joints. The incident light IN of the laser beam that has passed through one arm (not shown) of the articulated manipulator type laser surgical apparatus is reflected by the reflection point RQ of the plane mirror 31,
The reflected light OUT is transmitted to the other arm (not shown). The plane mirror 31 is fixed to the mirror holder 32. The mirror holder 32 is O in the mounting holder 36.
It is held movably through the ring 35 and the pull screw 33
And the tilted light is changed by the push screw 34 and the reflected light OU
The sending direction of T is changed. The mounting holder 36 is provided with a screw on the outer wall, and is screwed onto the inner wall screw of the mirror block 39 via the screw. Mirror block 39
Is connected to an arm joint (not shown). When the angle of the plane mirror is changed by a pulling screw or a push screw, the above-described conventional articulating reflecting mirror described above changes the position of the plane mirror (both the probe). And the reflection point RQ changes, making it difficult to match the optical axis of the reflected light OUT with the desired one, and therefore, it takes a lot of time to adjust the joint reflection mirror. There is. SUMMARY OF THE INVENTION In view of the above problems, the present invention provides a joint reflection mirror in which the reflection point does not change even if the angle of the plane mirror is changed, and the optical axis of the reflected light can easily match the desired one. With the goal. The articulation mirror of the present invention is a articulation manipulator-type articulation mirror for a laser surgical apparatus having a flat mirror surface and a central back surface. The spherical center of the reflection mirror part having a spherical surface on the mirror surface, and a part of the spherical surface of the reflection mirror part,
A mirror support portion attached to the joint so as to support the reflection mirror portion, an elastic member that slidably presses the spherical surface of the reflection mirror portion against the mirror support portion, and a spherical surface of the reflection mirror portion on the mirror support portion a reflection mirror portion while sliding rotating possess a reflection angle adjusting mechanism for setting the predetermined angle, the reflection
The mirror portion has a protrusion at the center of the spherical surface, and the end of the protrusion
Has a disk-shaped pressing portion extending outward, and the reflection angle
The adjusting mechanism is provided with the anti-reverse mechanism through the pressing portion of the reflecting mirror portion.
Sets the angle of the shooting mirror . When the angle of the reflection mirror portion is changed by the reflection angle adjusting mechanism, the reflection mirror portion changes the angle of the mirror surface while sliding the spherical surface on the mirror support portion. Therefore, the laser light incident on the spherical spherical center on the mirror surface is reflected without changing the reflection point. Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1A is a cross-sectional view showing an embodiment of the joint reflection mirror of the present invention, and FIG. 1B is a view of the pressing plate shown in FIG. The incident light IN of the laser beam coming from an arm (not shown) on the laser light source side is reflected at the reflection point RR of the plane mirror 11.
And reflected light OUT is sent out into an arm (not shown) on the handpiece side. The plane mirror 11 is fixed to one surface of the mirror holder 12. The other surface of the mirror holder 12 in the central portion, has a spherical portion 12 1 sphere center comes to the reflection point RR, yet the central portion the pressing plate 13 so as to be parallel to the plane mirror 11 to the end extends It is fitted. [0010] mounting holder 16 is fitted to the mirror block 19 connected to the arm of the joint (not shown), the portion of the inner wall extends inwardly to form a circular plate portion 16 1, the disc portion 16 1 an inner peripheral tip of which is shaped to abut the spherical surface portion 12 1 of the mirror holder 12. The pressing plate 13 fixed to the mirror holder 12 and the disc portion 16 1 of the mounting holder 16
A compression spring 15 (which may be a winding spring, a plate spring, or an annular elastic member) is inserted between the spherical spring portion 12 1 of the mirror holder 12 and the disc portion 16 1 of the mounting holder 16. Is slidably brought into contact with the inner circumferential tip. The push screws 14, 14 2 and 14 3 attached to the pressing plate 13 are used for adjusting the angle of the plane mirror. Next, adjustment of the plane mirror of this embodiment will be described. The push screws 14 1 , 14 2 , 14 3 are pulled out so as not to contact the mounting holder 16. Reflected light OUT
Set screws 14 1 , 14 2 , 1 so that
4 Push one or two out of three . When the orientation is set to a desired one, the other push screw is pushed and fixed to the extent that it contacts the mounting holder 16. The plane mirror 11 rotates with adjustment of the push screws 14 1 , 14 2 , 14 3 , but the rotation is performed while sliding the spherical surface portion 12 1 to the tip of the disc portion 16 1 of the mounting holder 16. , Reflection point RR
Is not changed, and only the direction of the reflected light OUT is matched with the desired optical axis. Further, since the push screws 14 1 , 14 2 , and 14 3 are provided on the pressing plate 13, even if they are adjusted, no stress is applied to the flat mirror 11 and the flatness is not lost. In the above embodiment, the three push screws 1 are used.
4 1, 14 2, 14 3 may have been adjusting the angle of the plane mirror 11, the present invention is not limited thereto, while sliding the spherical portion 12 1 in the disc unit 16 1, the plane Any mirror can be used as long as the angle of the mirror is adjusted and the mirror holder can be fixed so as not to apply unnecessary stress to the compression spring and the like after adjustment. As described above, according to the present invention, a spherical surface with a spherical center on the mirror surface is provided on the back surface of the mirror surface of the reflection mirror portion, and the angle of the mirror surface is slid while the spherical surface slides on the mirror support portion. since changing the reflection point if the input Shako to come to the spherical center is easy to become effective cause the optical axis of the reflected light does not move to match the desired. Further, since the reflection angle adjusting mechanism does not exert stress on the mirror surface, there is an effect that the flatness of the mirror surface is not impaired.
