If the ratio of the pitch of the grooves 3 to the diameter of the working part 2 falls below 0.3, the ejection of the pathological content is reduced due to the reduction in cavitation currents. If this ratio exceeds 1.5, the traumatic effect increases. The conical grooves 8 have a conicity of 10° to 20°. If the conicity angle is less than 10°, the ejection of the pathological content is reduced; if the conicity angle is greater than 20°,

Die Funktionsweise des Ultraschallinstrumentes ist die folgend··The functionality of the ultrasonic instrument is as follows··
einem (nicht abgebildeten) Generator zum Wandler 1 werden in diesem mechanische Längsschwingungen angeregt, die über das Verbindungselement 3 auf den Arbeitsteil 2 übertragen werden, welcher das biologische Gewebe berührt und die mechanischen Schwingungen in dieses weiterleitet. Dadurch, dass der Abschnitt des Verbindungselementes 3 in Form eines Kegele 4 auegebildet ist, der mit dem Wandler 1 in Berührung steht, wird die Schwingungsamplitude vergrösseit· Sine zusätzliche Vergrösserung der Schwingungsamplitude erfolgt durch Resonanzab-Stimmung des Instrumentes, d.h. durch die Wahl der Länge des Kegels 4, die dem Viertel der Läng· &Lgr; der m Ultraschallwelle in Längsrichtung gleich ist, der Lang· des zylindrischen Teils 7 des Verbindungselement·· 3, die &lgr; /2 gleich ist, und öer Lange d·· Abschnitt·· 5, die &Lgr; /4 gleich ist.A generator (not shown) for the transducer 1 excites longitudinal mechanical vibrations in the latter which are transmitted via the connecting element 3 to the working part 2 which comes into contact with the biological tissue and transmits the mechanical vibrations thereto. As the section of the connecting element 3 which is in contact with the transducer 1 is in the form of a cone 4, the vibration amplitude is increased. An additional increase in the vibration amplitude is achieved by tuning the instrument to resonance, i.e. by selecting the length of the cone 4 which is equal to a quarter of the length Λ of the ultrasonic wave in the longitudinal direction, the length of the cylindrical part 7 of the connecting element 3 which is equal to λ /2, and the length of the section 5 which is equal to λ /4.

The working part 2 of the instrument is inserted into an infected wound, for example into an tonsil lacuna filled with pathological contents, 1&eegr; Since the conical grooves 8 of the working part 2 with the larger cone base 9 are facing the transducer 1 and are oscillating simultaneously in the longitudinal and transverse directions,

In addition to the cleaning of the lacunae, a significant stimulating effect is achieved with the pathological content as a result of the contact of the lacuna walls with the working part 2 of the instrument.

Esdungagemous instrument for the treatment of chronic tonsillitis was carried out on 5 piglets and 10 dogs with modeled chronic pharyngeal tonsillitis. It

The reactive symptoms of inflammation as a result of the treatment disappeared within the usual time frame with a positive healing result without negative reflex effects on the vital organs and systems, so that clinical trials could begin.
Die Behandlung chronischer Tonsillitis unter Verwendung des Ultraschallinstrumentes wurde an 25 Kranken durchgeführt· Der klinische Effekt wurde bei einmaliger Einwirkung mit dem Instrument auf die llandellakunen während 1 bis 2 Minuten erslelt. Im Ergebnis wurde festgestellt, das· die blutungafreie Sanierung der Handeln kein· Komplikationen hervorrief· In «wei fällen waren reaktiv· Erscheinungen in Form eine· Temperaturanstiegs su verzeichnen.Treatment of chronic tonsillitis using an ultrasound instrument was carried out on 25 patients. The clinical effect was achieved with a single exposure of the instrument to the tonsillitis for 1 to 2 minutes. As a result, it was found that the bleeding-free treatment of the tonsils did not cause any complications. In two cases, reactive phenomena in the form of a rise in temperature were noted.

Dab«i wird dl· Behandlungsdauer wesentlioh geküret und dl· Notwendigkeit einer stationären Behandlung entüllt.Due to the special design features of the instrument, the surrounding tissue is only minimally damaged. The simple and suganglionic treatment of infected lesions, for example otitis media, using the instruments according to the invention makes the instrument practically usable in outpatient conditions without contraindications. This significantly reduces the duration of treatment and eliminates the need for inpatient treatment.
