Abstract

1390322 Ultrasonic probe for disintegrating body concretions R POHLMAN 12 April 1973 [22 April 1972] 17592/73 Heading A5R An apparatus for disintegrating concretions in body cavities comprises a tubular probe, Fig. 1, vibrated longitudinally ultrasonically, and loosely coupled at one end to a tubular impact element 2, the end of the tubular impact element remote from the coupling being constructed as a cutting edge and having a plurality of teeth 7, of undercut, trapezoidal construction, each tooth being twisted, so, that the outer edges of the teeth are circumscribed by a circle of diameter greater than the outer diameter D of the impact element, Fig. 3, and the inner edges are inscribed by a circle of diameter smaller than the internal diameter d of the impact element. The impact element 2 may be given radial and axial play on the end of the probe, and is retained in the probe 1 by pins 5, 5' engaged in slots 6, 6' in the impact element 2, or may be retained by a cap sleeve (13) Fig. 5 (not shown) secured to the probe 1. Alternatively, the element 2 may be supported by a helical spring (18) Fig. 6 (not shown) contacting the probe and the element, or by a resilient tube (22) Fig. 7 (not shown). The parts of the probe and/or impact element in contact are of rounded construction, Fig. 4 (not shown), or may be corrugated to give point contact. The probe tube is connected to an exhaust.
