1. A dissection tool, comprising:
- an elongated handle having a proximal end and a distal end;
an elongated dissecting element having a proximal end and a tapered distal end, the proximal end of the elongated dissecting element coupled to the handle and the elongated dissecting element extending from the distal end of the handle;
two ultrasonic transducers provided along the tapering of the distal end of the elongated dissecting element, the ultrasonic transducers provided on opposite sides of the elongated dissecting element; and
a fluid channel system extending from at least the proximal end of the elongated dissecting element to the distal end of the elongated dissecting element, the fluid channel system terminating in a port system having a plurality of apertures along the tapering of the distal end of the elongated dissecting element.

Abstract
Ultrasonic dissection instruments and methods provide for fluid delivery during subcutaneous dissection. An ultrasonic dissection tool includes a handle, a transducer and a dissecting member. The dissecting member extends from the distal end of the transducer, and a fluid channel system extends from at least the proximal end to the distal end of the dissecting member. The fluid channel system terminates in a port system. The port system may include one or more apertures, one or more channels, and be adapted to transport fluids such as, for example, irrigation fluids, fluids having analgesics, antibiotics, and combinations of fluids and agents.

9. A dissection tool, comprising:
-
at least two ultrasonic transducers; means, coupled to the ultrasonic transducers, for dissecting subcutaneous tissue employing an elongated dissecting element having a proximal end and a tapered distal end, the ultrasonic transducers coupled to the elongated dissecting element such that the ultrasonic transducers vibrates the elongated dissecting element to facilitate tissue dissection; and means for delivering a fluid through or along the elongated dissecting element of the dissecting means and to tissue subject to dissection, the fluid exiting the dissection tool through a port system having a plurality of apertures along the tapering of the distal end of the elongated dissecting element, wherein the at least two ultrasonic transducers are provided along the tapered distal end of the elongated dissecting element and the at least two ultrasonic transducers are provided on opposite sides of the elongated dissecting element. - View Dependent Claims (10, 11, 12, 13)
