Ultrasonic debrider probe and method of use

摘要

An ultrasonic medical probe has an elongate shaft with a head portion having a distal end face oriented at least partially transversely to a longitudinal axis of the shaft. The head portion has a lateral surface extending substantially parallel to the longitudinal axis, the lateral surface being provided with outwardly or radially extending projections. The shaft of the probe is provided with an internal longitudinal channel or bore and at least one ancillary or tributary channel communicating at an inner end with the longitudinal channel or bore and extending to the lateral surface. The ancillary or tributary channel has an outer end disposed in a region about the projections. The projections may be finely configured and distributed so as to form a knurled surface on the head portion.
