Abstract

The transducer centrepiece is fitted with two vibrator aggregates which are fixed by means of steel bolts to outward angled faces to form a trapezoid combination. The centrepiece incorporates a fixing socket for the attachment of a vibration transmitter at right angles to the plane of the vibrators. A variety of tools or instruments such as drills, cutters, grinders, can be attached to the transmitter. The vibrators and transmitter are arranged to vibrate at half of the ultrasound wavelength in opposing phases by polarity reversal of the supply current. The configuration induces vibrations both axially and transversely for increased efficiency. This mode of operation also facilitates the insertion of long flexible probes or catheters in medical applications.

Piezoelektrischer WandlerPiezoelectric converter

Die Erfindung bezieht sich auf einen neuartigen piezoelektrischen Wandler, dessen Schwingungeübertragungsglied neben den bekannten hubartigen Schwingungen auch zusätzliche Dreh- bzw. TorsionsschYfingungen in Mikrogrenzen ausführt.The invention relates to a novel piezoelectric transducer, its vibration transmission member In addition to the known stroke-like vibrations, it also carries out additional rotational and torsional vibrations within micro limits.

Alle bekannten piezoelektrischen Yerbundvibratoren schwingen bei Erregung lediglich hubartig in Richtung der Längsachse des Arbeitsansatzes.All known piezoelectric Yerbund vibrators only vibrate in a stroke-like manner in the direction of the longitudinal axis when excited of the work approach.

Zwecks Steigerung der Leistung solcher Wandler und ihrer Arbeitsansätze, seien dies nun Sonden zur Zertrümmerung ▼on Blasensteinen, Hohlbohrer, Fräser, Schneidscheiben oder dergleichen wird erfindungsgemäß Torgeschlagen, daß solche Arbeitsansätze neben ihren hubartigen Schwingungen auoh Torsionsschwingungen in Mikrogrenzen ausführen·In order to increase the performance of such converters and their work approaches, these are now probes for shattering ▼ on bladder stones, hollow drills, milling cutters, cutting disks or the like is struck by the invention that such In addition to their stroke-like vibrations, work approaches also carry out torsional vibrations within micro-limits

Es wird hierdurch eine Erhöhung der Arbeitsgeschwindigkeit durch die unterschiedlichen Schwingungsmoaente erreicht. So wird auch z.B. bei dem Einsatz τοη flexiblen Sonden die Überwindung τοη nicht geraden Fegen, wie z.B. Biegungen und Windungen im Körper eines Patienten durch die zusätzlichen Torsionssohwingungen wesentlich erleichtert.This increases the working speed due to the different vibration modes. For example, when τοη flexible probes are used, overcoming τοη non-straight sweeps, such as bends and twists in the body of a patient, is significantly facilitated by the additional torsional oscillations.

Das Wesen der Erfindung wird darin erblickt, daß ein trapezförmiger Verbundvibrator aus zwei mechanisch vorgespannten, mit dem Alukörper mittels Stahlbolzen verbundenen 1J/2 Kolbenschwingern besteht, die durch Umpolung der Betriebsspannung oder der Polarität der piezoelektrischen Scheiben in Gegenphase schwingen, wobei der Alukörper zur Aufnahme eines zu verspannenden, sich nach dem freien Ende zu konisch verjüngenden 772 Schwingungsübertragungsgliedes dient, das zur lösbaren Aufnahme des Arbeitsansatzes bestimmt ist.The essence of the invention will be seen in the fact that a trapezoidal composite vibrator of two prestressed mechanically connected to the aluminum body by means of steel bolts 1 J / 2 piston vibrators is that oscillate by reversing the polarity of the operating voltage or the polarity of the piezoelectric discs in opposite phase, wherein the aluminum body for receiving a 772 vibration transmission member to be braced, tapering conically towards the free end, which is intended for the detachable reception of the working attachment.
