METHOD OF FORMING CHAMFERED BLIND HOLE IN SURGICAL NEEDLE USING DIODE-PUMPED ND-YAG LASER

摘要

PPROBLEM TO BE SOLVED: To provide a pulse laser drilling method to drill a chamfered hole in a surgical needle by using single laser beams. PSOLUTION: In the method for drilling a hole by laser beams in a surgical needle 190, a diode pulsed laser to produce laser beams 360 consisting of a train of high energy pulses is used. A chamfered blind bore hole is formed in the surgical needle with laser beams. PCOPYRIGHT: (C)2004,JPO&NCIPI
