FIELD: medicine.
SUBSTANCE: method is realised by formation of hole for introduction and fixation of one ligature end in butt end surface of surgical needle without eye, made from stainless steel. Hole is made by irradiation of butt end of needle working piece, whose diametre is from 6 to 20 mcm larger than diametre of surgical needle, which constitutes less than 150 mcm, due to irradiation by one pulse of laser ray of specified duration, isolated from pulse radiated by laser, after which section, whose diametre is larger than needle diametre is removed. In other version of method duration of pulse separated from pulse radiated by laser is equal or less than 35 mcs. In third version of method realisation pulse, isolated from pulse radiated by laser if formed by multiple pulses of short duration.
EFFECT: group of inventions will make it possible to create holes of satisfactory quality in butt end of thin surgical needle, without puncture of side wall or hole bending.
