The surgical lighting system with large angular aperture and extensible illuminator extended with large angular aperture

摘要

b illuminator extending from small arms d .The present invention relates to a gleam of variable stiffness and small arms.A delivery system and a surgical lighting of small arms, which comprises: a light source (12) for providing a beam of light; an optical cable (14).Optically coupled to the light source for transmitting and receiving the beam of light; a hand piece (10), operavelmente coupled to the optical cable; an optical fiber (22), operavelmente ACO joke to the hand piece.In the optical fiber is optically coupled to the optical cable for transmitting and receiving a beam of light to illuminate an area; and a cannula (16), operavelmente coupled to the hand piece.For housing and direcionara optical fiber, in which the cannula is operable to be extended and retraida of the hand piece for varying the length of the cannula which extends from the hand piece.And in which the optical fiber is operavelmente connected to the cannula, such that the distal end of the optical fiber and the distal end of the cu00e2nu it remain consistent.Although the length of the cannula which extends from the hand piece is varied. The optical fiber, the cannula and the hand piece are made of biocompatible materials.
