FIELD : medicine.SUBSTANCE : invention relates to ophthalmology. Ultrasonic needle for ophthalmosurgery is designed for dissection and aspiration of vitreous body and other eye tissues. Needle comprises a bushing for connection to an ultrasonic instrument, a cannula having at least one working hole on the distal end and having a lumen extending from the proximal end of the cannula to the distal end. Cross section of working opening is smaller than cross-section of lumen of cannula. In the side wall of the cannula at the distal end, a through slotted incision is also made, located at angle of 90?to lengthwise axis with slot length making 1/2 of circumference of outer surface of cannula.EFFECT : use of the invention enables higher suction force and enables to create an additional emulsifying effect in the projection of the opening to increase efficiency of cutting dense pathological structures.1 cl, 6 dwg, 2 ex
