- the end surface of the other end of the optical fiber 131 forms an inclined surface 131a, and one side of the other end is sharply formed. Therefore, the laser beam transmitted through the optical fiber 131 is reflected by the refractive index difference in the inclined surface 131a and irradiated toward the lateral direction.
- the cover member 132 is configured to surround the end portion of the optical fiber 131 is irradiated with the laser. This is to prevent the laser reflection characteristic of the inclined surface from changing according to the property of the material in which the end of the optical fiber 131 is exposed to the outside and contacts the inclined surface.
- the cover member 132 is made of a transparent material, the laser irradiated from the end of the optical fiber 131 is irradiated to the surgical site through the cover member 132.
- the expansion unit 150 shown in Figure 6a is a configuration that can expand the internal space of the tissue by applying a mechanical force inside the human tissue during surgery.
- the extension part 150 is composed of a body 151 having an elongated member shape, such as a wire, and an inflatable member 152a which is selectively inflatable at an end thereof.
