The lower end of the second spring 86 is fixed to the bottom plate 240 fixed to the column 25, and rotates with the column 25 around the first shaft 26. By doing so, even if the column 25 rotates, the second spring 86 is not twisted, and the tension of the same condition is always applied.

The tension force of these springs 84 and 86 and the frictional force at each of the second joint portion 36 and the third joint portion 38 allow the first arm 30 and the second arm 32 to be deployed at desired positions. Can be stopped and positioned. The stand 28 can also be supported in a desired direction by the frictional force in the first joint 34. These joints 34, 36, 38
The frictional force can be adjusted by tightening the joint.

Next, the stand 28 and the handpiece 27 will be described with reference to FIGS.

First, the irradiation end 7a of the optical fiber 7 is arranged on the tip side of the handpiece 27. Handpiece 2
The tip side of 7 has a first extension 100 and a second extension 102. By providing the first and second extension parts 100 and 102, the gap 104 can be formed. In this way, the gap 104
Is formed so that the operator can see whether or not the laser light is successfully applied to the affected part when the tips of the first and second extension parts 100 and 102 of the handpiece 27 are applied to the treatment site. This is because

The stand 28 that supports the handpiece 27 has a first support member 110 and a second support member 115 made of resin, for example.

The first support member 110 is composed of a first divided body 112 and a second divided body 113 as particularly shown in FIG. The second divided body 113 is preferably screwed into the first divided body 112 and attached to the first ring portion 122 of the handle 120. The first ring portion 122 of the handle 120 is shown in FIG.

The second support member 115 is a disc-shaped receiving member. The second ring portion 1 of the handle 120 by the screw 124.
It is attached to 26. The second ring portion 126 is shown in FIG.
Shown in.

In the state where the handpiece 27 is supported, the thick grip portion of the handpiece 27 is supported by the first support member 110, and the first and second extension parts 100, 10 are provided.
The lower end of 2 is supported in the recess 117 of the second support member 115. When the operator uses the handpiece 27, it may be pulled out in the direction of arrow A shown in FIG.

Most of them are made of aluminum metal.

The bracket 130 to which the pulleys 90 and 91 shown in FIG. 2 are attached, and the support column 25 connected to the members in the third joint 38, and the pulleys 88 and 88, respectively.
The bracket 70 to which 89 is attached is connected by a bar member 132 also called a hard wire. Wire 1
32 supports the bracket 25 of the support 25 and the second joint 36.
The reason for connecting is for the following reasons.

In order to keep the positions of the pulleys 88 and 89 at a constant position with respect to the second joint member 36, the hard wire 13
Connected by two. That is, if the wire 132 is not present, the positions of the pulleys 88 and 89 change when the first arm 30 and the second arm 32 are deployed or stored.
The distance between the pulleys 88, 89 and the pulleys 90, 91 cannot be made constant, and the first wire 80 and the second wire 82 loosen. Therefore, the first arm 30 and the second arm 32 cannot be kept at the predetermined positions.

In use, the operator first turns on the level setting switch 5 shown in FIG. The first arm 30 and the second arm 32 are folded. The operator holds the handle 120 and deploys the first arm 30 and the second arm 32 to bring the other end 24 of the movement operating means 20 closer to the affected part of the bed B.

For example, FIG. 1 shows a state in which the moving operation means 20 is expanded.

In this unfolded state, the first arm 30 and the second arm 32 are moved through the first wire 80 and the second wire 82 by the tensile force of the springs 84 and 86 shown in FIG.
Support at °. The weight of the moving operation means 20 and the first wire 8
When a force that causes the moving operation means 20 to drop downward is generated due to the difference between the pulling force of 0 and the second wire 82, the moving operation means 20 holds the friction surface of the first to third joint portions 34, 36, 38.

Next, the operator removes the handpiece 27 from the stand 28, and the first piece of the handpiece 27 shown in FIG.
The extension part 100 and the second extension part 102 are applied to the affected part. Then, the operator steps on the foot switch 10 shown in FIG. 1 to irradiate the affected area with the laser light L through the hand piece 27 for treatment.

Each time the irradiation treatment is completed, the handpiece 27 is returned to the stand 28 near the affected part and the handpiece 2
Support 7. As a result, the operator does not have to return the handpiece to the main body 2. The upper portion and the lower portion of the handpiece 27 are firmly and tightly supported by a stand 28 as shown in FIG. Therefore, the surgeon holds the handle 1
Even if the movement operation means 20 is moved while holding the hand 20, the handpiece 27 does not come off from the stand 28 at all.

Since the optical fiber 7 is supported by each arm of the moving operation means, it does not hang down on the floor. Therefore, the surgeon does not step on or catch the optical fiber. Further, it does not contaminate the optical fiber.

The present invention is not limited to the above embodiment. For example, instead of using the foot switch 10 shown in FIG. 1, a hand switch may be provided on the handpiece 27.

[0043]

According to the invention of claim 1, an irradiation member such as a handpiece can be supported by a supporting means such as a stand which is fixed in a space near the affected part when not in use, and the operator can fix the irradiation member. When used, the irradiation member can be removed from the supporting means to treat the affected area. In other words, the operator does not have to go to or place the irradiation member on the main body, and because it is a support means that can be moved, the surgery is efficient and safe without having to worry about where the irradiation member is placed or lost. You can do it. In particular, when treating the affected area many times such as bruising treatment, it is safe because the operator does not drop the irradiation member or accidentally irradiate the laser beam.

According to the second aspect of the invention, the operator can move the free end of the moving operation means to the vicinity of the affected area freely and surely by using the handle.

According to the third aspect of the present invention, the operator or the third person can perform smooth treatment without paying attention to the optical fiber.
