Neurosonic aspirator and method
First Claim
1. A procedure for rapidly removing neurological tissue that has been exposed to view comprising the steps of:
- vibrating a tool tip that has a longitudinal axis at an ultrasonic frequency and in a manner such that substantially all of said vibration is transverse to the longitudinal axis of the tip;
sweeping the tip back and forth over the surface of and in contact with the exposed tissue, said sweeping motion of the tip occurring in a plane generally parallel to said transverse vibration to disintegrate the tissue layer by layer; and
,aspirating said disintegrated tissue simultaneously with said sweeping step.

Abstract
Method and apparatus are disclosed for use in surgically removing tumorous neurological tissue which apparatus comprises a handpiece mounting a hollow tool tip vibrating transversely to its long axis in the ultrasonic range, means for introducing fluid adjacent the tool tip to flush the operative site area, and means adjacent the tool tip for withdrawing the fluid mixture from the site. The method comprises applying an ultrasonically vibrated tool to tumorous nerve tissue, while simultaneously introducing irrigation fluid to flush the area of the tissue and withdrawing the resulting mixture from the area adjacent the tool.
