Prior Art FIG. 3 is a diagram for explaining an example of the use of a conventional laser scalpel. In the figure, 1 is a light guide from which a laser beam is emitted, and 2 is a laser beam emitted from an end face 1a of the light guide 1. hemispherical lens for focusing light, 3
is a tapered conical light guide into which the laser light focused by the hemispherical lens 2 is introduced;
The laser light introduced into the light guide 3 travels toward the tip 3a while being reflected by the outer surface of the light guide 3. During this time, the angle of reflection with respect to the outer surface gradually increases, and the laser light travels toward the tip 3a. As it goes closer to the tip, it becomes easier to leak to the outside from the outer surface of the light guide 3, and a powerful laser beam is emitted from near the tip. Therefore, the tip of the light guide 3 or the outer surface of the tip can be brought into contact with or close to the affected area and used as a laser scalpel for treatment.

Therefore, the light guide, that is, the laser scalpel 3,
Since the tip 3a is cut into a flat surface 3a,
The light distribution curve of the laser light emitted from the laser scalpel 3 becomes discontinuous as shown by dotted line A in the figure, and almost no laser light is emitted in the direction of the horizontal plane B of the tip, and the cutting ability in this direction is reduced. There were very few of them, and they were extremely difficult to use.

Configuration Fig. 1 is a diagram showing an embodiment of the laser scalpel according to the present invention. In the present invention, the laser scalpel consists of a tapered conical light guide, the tip 3b of which is a part of a sphere as shown in the figure. It is formed in an arc shape, and by doing so, the light distribution curve of the laser light emitted from the laser scalpel 3 becomes almost uniform in all directions without discontinuities as shown by the dotted line C. When making an incision, the laser beam is emitted to the front of the laser scalpel in advance of the tip of the laser knife, making the incision much easier.

FIG. 2 is a diagram showing a modified embodiment of the present invention, in which the entire tip 3c of the laser scalpel 3 is formed into a substantially spherical shape, and the tip of the laser scalpel 3 is formed into a spherical arc surface. By doing this, the light distribution curve of the laser light emitted from the laser scalpel 3 becomes as shown by the dotted line D, and the emission of laser light can be concentrated at the tip of the laser scalpel 3, further improving the cutting ability. can be done.
