One female null for contact laser type surgery

摘要

A unitary contact laser scalpel for orthopaedic or other operative procedures comprises a tapered conical member (26) in part of ceramic or similar material charcterised by high strength and low coefficient of thermal conductivity. A cylindrical passage (42) is formed along and through the central axis of the ceramic member (26) into which an optical fibre is secured. The distal end (44) of the optical fibre may be oriented flush with the tapered end of the conical member (34) or it may define a tapered extension of the ceramic material. The tapered end of the conical member may have a narrow diameter generally of the order of twice that of the optical fibre and may be coated with an enamel material. Alternatively, a larger diameter optical fibre may be used with the combination of ceramic and fibre being formed with a conical contour. IMAGE
