摘要： An infrared fiber cable having a protective tube isolating the light for collimation which is a visible light. An infrared fiber is accommodated in the protective tube and adapted to conduct and emit an invisible light. Light emitting means is disposed around the infrared fiber and adapted to emit the light for collimation. The infrared fiber cable further includes a member adapted to allow the invisible light to pass therethrough but reflect the light for collimation. Also, an apparatus for preventing erroneous emission for a laser scalpel to be attached to such an optical fiber is provided. The apparatus operates to control emission of the laser beam for surgical operation in response to the position of the emission end of the optical fiber with respect to the object to be surgically operated.
