摘要:
A needle for use with an ultrasonic handpiece for dissecting and aspirating vitreous tissue includes a cannula having a lumen extending from a port adjacent a cannula distal tip to a cannula proximal end. The cannula port has a cross-sectional area less than a cross-sectional area of the cannula lumen. A hub attached to the cannula proximal end attaches to the ultrasonic handpiece. A needle lumen is formed from the cannula port to a proximal end of the hub. A length of the needle lumen is approximately an odd quarter of a drive frequency wavelength of the ultrasonic handpiece and a cannula length measured from the cannula distal tip to a distal end of the hub is long enough to extend from an incision site across a posterior segment of an eye.
