Ultrasonic debrider probe and method of use
First Claim
1. An ultrasonic medical probe comprising an elongate shaft provided with a head portion, said head portion having a distal end face oriented at least partially transversely to a longitudinal axis of said shaft, said head portion having a lateral surface extending substantially parallel to said longitudinal axis, said lateral surface being provided with at least one outwardly or radially extending projection, said shaft being provided with an internal longitudinal channel or bore, said head portion being provided with at least one ancillary or tributary channel communicating at an inner end with said longitudinal channel or bore and extending to said lateral surface.

Abstract
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.

12. A surgical method comprising:
-
providing a probe vibratable at least one ultrasonic frequency, said probe having a distal end face oriented at least partially transversely to a longitudinal axis of said shaft, said probe also having a lateral surface extending substantially parallel to said longitudinal axis, said lateral surface being provided with at least one outwardly or radially extending projection; bringing said lateral surface together with said projection into contact with organic tissues of a patient; during the contacting of said tissues with said lateral surface and said projection, energizing said probe to vibrate said lateral surface and said projection at said ultrasonic frequency; and during the contacting of said tissues with said lateral surface and said projection, conducting liquid to said lateral surface in a region about said projection via a channel in said probe, said channel extending to said lateral surface. - View Dependent Claims (13, 14, 15)

17. A surgical method comprising:
-
providing a probe vibratable at least one ultrasonic frequency, said probe having a head portion and a longitudinal channel, said probe being provided with a sheath defining an annular channel about said probe, said probe also having at least one transverse channel communicating at an inner end with said longitudinal channel and at an other end with said annular channel; bringing said head portion into contact with organic tissues of a patient; during the contacting of said tissues with said head portion, energizing said probe to vibrate said head portion at said ultrasonic frequency; and during the contacting of said tissues with said head portion, conducting liquid to said annular channel from said longitudinal channel through said transverse channel.
