A needle for phacoemulsification contains fixing elements comprising the threaded part and elements for installation and removal of the needle from a holder, and also tubular part, for transporting of pulp. The tubular part ends with a bell area and sloping to its axis butt-end flat surface that forms shock elliptoid circular surface and cutting edge of needle. On the butt-end surface of bell part on all length of shock elliptoid circular surface equal tapered teeth are made 0.35 high, that exceeds the amplitude of axial vibrations of the needle, and with a step that equals . |
