Abstract

An ultrasonic medical treatment probe has a head with a distal-most circular rim extending along an endless uninterrupted perimeter around a broad recess and formed with a series of serrations or teeth. The rim is thin in comparison to the width of the recess. The serrations or teeth preferably extend continuously along an entire circumference or length of the rim. The probe head is provided along the rim with a plurality of notches or openings communicating with the recess.

First claim

What is claimed is:

1 . An ultrasonic medical treatment probe comprising: a shaft or shank; a connector at one end of said shaft or shaft configured for coupling to a source of ultrasonic vibratory energy; and a probe head at an end of said shaft or shank opposite said connector, said probe head including a recess opening onto a distal end plane, said probe head having a distal-most rim extending along an endless uninterrupted perimeter around said recess, said rim being formed with a series of serrations or teeth.

2 . The probe defined in claim 1 wherein said distal-most rim is disposed in a plane.

3 . The probe defined in claim 2 wherein said distal-most rim is circular.

4 . The probe defined in claim 3 wherein said probe head has a cup-shaped configuration, with said rim constituting an edge of said probe head.

5 . The probe defined in claim 4 wherein said serrations or teeth extend continuously along an entire circumference of said rim.

6 . The probe defined in claim 5 wherein said plane is oriented perpendicularly to an axis of said shaft or shank.

7 . The probe defined in claim 1 wherein said probe head has a cup-shaped configuration, with said rim constituting an edge of said probe head.

8 . The probe defined in claim 1 wherein said rim is circular.

9 . The probe defined in claim 1 wherein said serrations or teeth extend continuously along an entirety of said rim.

10 . The probe defined in claim 1 wherein said probe head is provided along said rim with a plurality of notches or openings communicating with said recess.

11 . The probe defined in claim 1 wherein said probe head is provided along said rim with exactly four notches or openings communicating with said recess.

12 . A wound debridement method comprising: providing an ultrasonic probe having a shaft or shank, a connector at one end of said shaft or shaft configured for coupling to a source of ultrasonic vibratory energy, and a probe head at an end of said shaft or shank opposite said connector, said probe head including a recess opening onto a distal end plane, said probe head having a distal-most rim extending along an endless uninterrupted perimeter around said recess, said rim being formed with a series of serrations or teeth; placing said rim including said serrations or teeth in contact with a target surface of a patient; moving said probe so that said rim moves in a predetermined pattern parallel to and along said target surface while said rim including said serrations or teeth is in contact with said target surface; and during the moving of said probe, generating an ultrasonic standing wave in said probe to vibrate said rim and thereby debride said target surface.

13 . The method defined in claim 12 wherein during the moving of said probe, said distal-most rim is moved laterally within a plane constituting at least a portion of said target surface.

14 . The method defined in claim 12 wherein said plane is oriented perpendicularly to an axis of said shaft or shank.

15 . The method defined in claim 12 wherein said rim is vibrated at velocities of 10 to 18 m/s RMS.
