Abstract

An ultrasonic frequency surgical dissecting device including a handpiece with a surgical blade that vibrates in a direction transverse to a long axis passing through the handpiece and blade for improved cutting and coagulation

Claims

1. A surgical handpiece with a surgical blade that vibrates at ultrasonic frequencies for cutting and coagulating animal tissue, the surgical handpiece and surgical blade comprising:

a long axis passing through the surgical handpiece and surgical blade;

a most distal portion of the surgical blade that is disposed away from the surgical handpiece for contacting tissue of a patient; and

the most distal portion of the surgical blade having a vibratory motion that is substantially perpendicular to the long axis.
