Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
197 words
A laser light irradiation apparatus for irradiating a living tissue with laser lights to treat the tissue by bringing the end face of the apparatus into contact with the tissue, comprising: an optical fiber; and a substantially elongated chip disposed in front of said optical fiber for transmitting therethrough laser lights incident thereon from the front end of said optical fiber to emit the transmitted laser lights toward said object living tissue, said chip being formed with a hole extending from the center of the rear end face of the chip to a point along the length thereof, said optical fiber having an outer diameter smaller than that of said chip, said optical fiber being covered with a clad on the outer periphery of a core thereof, said clad being protected by a plastic sheath, the core being exposed along a length of the optical fiber at the front end portion thereof, said exposed portion being inserted into said hole, the rear end portion of said chip being made integral with the sheath or clad portion of the optical fiber by linking means, said linking means not being substantially projected beyond the outer periphery of the chip.
Claim 2
Dependent Claim
197 words
A laser light irradiation apparatus for irradiating a living tissue with laser lights to treat the tissue by bringing the end face of the apparatus into contact with the tissue, comprising: an optical fiber; and a substantially elongated chip disposed in front of said optical fiber for transmitting therethrough laser lights incident thereon from the front end of said optical fiber to emit the transmitted laser lights toward said object living tissue, said chip being formed with a hole extending from the center of the rear end face of the chip to a point along the length thereof, said optical fiber having an outer diameter smaller than that of said chip, said optical fiber being covered with a clad on the outer periphery of a core thereof, said clad being protected by a plastic sheath, the core being exposed along a length of the optical fiber at the front end portion thereof, said exposed portion being inserted into said hole, the rear end portion of said chip being made integral with the sheath or clad portion of the optical fiber by linking means, said linking means not being substantially projected beyond the outer periphery of the chip.
Claim 3
Dependent Claim
24 words
A laser light irradiation apparatus as defined in Claim 1 in which the front end portion of said chip is substantially spherical in shape.
Claim 4
Dependent Claim
25 words
A laser light irradiation apparatus as defined in Claim 1 in which the front end portion of the said chip is bent into the J-shape.
Claim 5
Dependent Claim
59 words
A laser light irradiation apparatus as defined in Claim 1 in which said linking means comprises a thin walled heat resistant sleeve, the front end portion of said sleeve being inserted into said hole, said sheath of said optical fiber being adapted into the base portion of said sleeve so that said chip is linked with said optical fiber.
Claim 6
Dependent Claim
69 words
A laser light irradiation apparatus as defined in Claim 1 in which said linking means comprises a heat resistant sleeve, the front end portion of said sleeve being adapted on a step portion formed on the outer periphery of the rear end of said chip, the sheath of said optical fiber being adapted into base portion of the sleeve so that said chip is linked with said optical fiber.
Claim 7
Dependent Claim
56 words
A laser light irradiation apparatus as defined in Claim 4 or 5 in which the base portion of the heat resistant sleeve is secured to the outer periphery of the sheath by caulking the sleeve on the sheath while the sheath of said optical fiber is adapted into the base portion of the heat resistant sleeve.
Claim 8
Dependent Claim
54 words
A laser light irradiation apparatus as defined in Claim 4 or 5 in which the inner surface of the base portion of the heat resistant sleeve is roughed along the length thereof, said sheath of said optical fiber being inserted into the roughed inner surface of the base portion of said heat resistant sleeve.
Claim 9
Dependent Claim
33 words
A laser light irradiation apparatus as defined in Claim 1 or 2 in which the front end of said heat resistant sleeve is bonded to the chip with a heat resistant bonding agent.
Claim 10
Dependent Claim
34 words
A laser light irradiation apparatus as defined in Claim 1 or 2 in which heat absorbing powders are applied on the outer surface of the chip with a binder which transmits laser lights therethrough.
