る。Prior Art FIG. 4 is a diagram for explaining an example of a conventional laser knife. In the figure, 1 is a laser knife chip, 2 is an optical fiber through which laser light is transmitted, and as is well known, an optical fiber 2 is used. The guided laser beam is incident on one end 1a of the laser knife contact-type ceramics chip 1 and is emitted from the other end (chip tip) 1b side according to various chip shapes. Thus, in the above-mentioned conventional technique, in order to focus the laser light on the tip of the chip, the tip end side 1b is made into a conical shape, and as shown in the drawing, the laser light is provided at the outer side (inclined part) of the conical shape. Is reflected, condensed and emitted.

ーザメスチップ内の導入することができる。Structure FIG. 1 is a side sectional view for explaining an embodiment of a laser knife chip according to the present consideration. In this embodiment, the laser light incident side 1a of the laser knife chip 1 is a spherical surface, an elliptical surface, It is formed on a convex surface such as a parabolic surface or a hyperbolic surface, and the laser light emitted from the optical fiber 2 is condensed by the convex surface and introduced into the chip 1. The operation of the laser light introduced into the chip 1 is the same as that of the prior art shown in FIG. 4, but in the prior art, as shown in the drawing, the laser light incident side end face 1a is formed into a flat surface. However, since the incident side end face has no light collecting function, the light collecting efficiency of the chip is inferior to that of the present invention shown in FIG. In addition,
According to the present invention, since the incident side end surface 1a of the chip 1 is formed into a convex surface, the laser beam is easily reflected at the incident side end surface. Therefore, in order to prevent this reflection,
If the antireflection coating is applied to the convex surface on the laser light incident side, the laser light from the optical fiber can be more effectively introduced into the laser knife chip.

As shown in the drawing, after the laser light emitted from the optical fiber 1 is collimated by the lens 3, This is introduced into the laser scalpel chip 1 according to the present invention. By doing so, the aberration can be reduced by the lens 3.

In this embodiment, the laser scalpel chip 1 has a central portion 1c having a large refractive index and a peripheral portion. It is composed of a converging ceramic consisting of a portion 1d having a small refractive index, and the laser light introduced into the laser knife chip 1 is focused on the one having a large refractive index at the central portion, and the center of the tip of the tip is focused. The light is collected and radiated.
