High efficiency ultrasonic surgical aspiration tip

The art of the present invention relates to ultrasonic surgical devices in general and more particularly to a high efficiency ultrasonic tip for use in neurosurgery and other surgical disciplines. The use of ultrasonic aspirators in neurosurgery is well understood and recognized in the field of neurosurgery. Ultrasonic aspiration provides for emulsification and in situ evacuation of intracranial tumors. In this way, retraction of eloquent brain is minimized, while disruption and removal of tissue is advanced. A high efficiency ultrasonic surgical aspiration tip apparatus and accompanying method for surgical use. The apparatus has one or more substantially "V" or "U" shaped cuts in a contacting. The apparatus and method of use provides a cutting action at the contacting end when the tip is ultrasonically excited. The apparatus and method of use further provides a substantially uniform ultrasonic and aspiration field due to the positioning and shape of the substantially "V" or "U" shaped cuts. The aforesaid further allows a surgeon to position the ultrasonic generator handpiece at any rotational angle for provision of the benefits cited.
