1. A vibrating hand held surgical instrument for loosening tissue of a patient comprising:
a motor;
a rotating drive shaft having a first end and a second end, the first end operatively connected to the motor;
a vibration actuator including an eccentric rotating mass operatively connected to the drive shaft, the eccentric rotating mass remaining outside the patient, the eccentric rotating mass positioned in a proximal housing; and
a cannula extending distally of the eccentric rotating mass, wherein the motor is configured to rotate the eccentric mass to cause the cannula to vibrate to loosen tissue, and the cannula is operatively connected to the vibration actuator and removable from the vibration actuator for interchangeability of the cannula, the cannula having a lumen extending therein;
wherein the cannula has an angled proximal region within the proximal housing of the instrument, the angled proximal region extending at an angle to a longitudinal axis of the instrument, wherein the angled proximal region is distal of the motor, the lumen of the cannula extending through the angled proximal region and the proximal end of the cannula extending outside a side of the proximal housing to connect with an external fluid source.
