1. An apparatus comprising:

  • a hollow needle having a central cavity and a beveled cutting edge at the distal insertion end thereof; and

    a tubular laser fiber that is inserted into the central cavity of the hollow needle,wherein the tubular laser fiber is coaxial with an axis of the central cavity and is positioned such that a distal end of the tubular laser fiber is retracted within the central cavity corresponding to a plane defining a beginning of the beveled cutting edge, such that the tubular laser fiber is fully enveloped by an inner wall of the hollow needle surrounding the central cavity,wherein the tubular laser fiber is directly affixed to the inner wall of the hollow needle whereby the tubular laser fiber and the hollow needle become one non-detachable unit,whereby the apparatus in the above configuration facilitates unobstructed entry of the apparatus through skin and deeper structures of a human body without the requirement of additional elements, andwherein the hollow needle is a Quincke-type spinal needle.
