Ultraschall-Prüfsonde, insbesondere zur Anwendung in der medizinischen Diagnostik.Ultrasonic test probe, in particular for use in medical Diagnosis.
Die Erfindung betrifft einen Ultraschall-Prüfkopf mit be onders kleinen Abmessungen und spezieller Halterung. Sein Anwendungsgebiet ist neben der allgemeinen zerstörungsfreien Prüfung vor allem die medizinische Diagnostik.The invention relates to an ultrasonic probe with be onders small dimensions and special bracket. Its field of application is in addition to the general non-destructive testing especially medical diagnostics.
Bekannt sind Ultraschall-Prüfköpfe, mit denen durch Umwandlung von elektrischer Energie in akustische und umgekehrt das Aussenden und Empfangen von Ultraschall-Impulsen zur zerstörungsfrei*n Prüfung möglich ist. Jedoch sind die Abmessungen so groß, daß eine Anwendung gemäß der Forderung, die die Erfindung erfüllt, nicht möglich ist.Ultrasonic probes are known, with which by conversion from electrical energy to acoustic and vice versa the sending and receiving of ultrasonic pulses for non-destructive * n Examination is possible. However, the dimensions are so large that an application according to the requirement that meets the invention, not possible.
Der Erfindung liegt die Aufgabe zugrunde, eine Ultraschall-Prüfsonde in den menschlichen Körper so einzuführen, daß z.B. Organ untersuchungen, wie zum Zwecke der Enzepha1ographie, oder auch eine Wirbelsäulendiagnostik möglich sind. The invention is based on the object of introducing an ultrasonic test probe into the human body in such a way that, for example, organ examinations, such as for the purpose of encephalography, or also spinal column diagnostics are possible.
Die Erfindung betrifft eine Ultraschall-Prüfsonde, insbesondere für den Gebrauch in der medizinischen Diagnostik,durch Einführen der Sonde in den Körper des Patienten mit elektrischer Verbindurg zum üblichen Ultraschall-Prüfgerät, wobei ein sehr kleiner Piezokristall an oder in der Spitze eines dünnen, biegsamen Rohrs oder Schlauchs a^jjebracht ist.The invention relates to an ultrasonic test probe, in particular for use in medical diagnostics, through insertion the probe into the patient's body with electrical connection to the usual ultrasonic testing device, with a very small piezo crystal on or in the tip of a thin, flexible tube or hose is attached.

Einzelheitan und Abwandlung der erfinderischen Anordnung gehen aus der Abbildunghervor.Go to detail and modification of the inventive arrangement from the figure above.
Die Abbildung zeigt schematisch die Prüfsonde im Schnitt. Durch die Bohrung im Griff 1 ist eine Spiralfeder 3 geführt. Die Feder 3 ist mit dem Bauteil 2, das am Griffende als Rändeldrehteil ausgebildet ist, fest verbunden. Am Ende der Sonde ist die Feder 3 mit einem Träger 8 eines Ultraschall-Wandlers 9 fest verbunden, Die Feder 3 umschließt ein Verbindungskabel k, v.elches an einen Stecker 10 und den Ultraschall-Wandler 9 angeiötot ist. Der Stecker 10 dient der Verbindung der Sonde mit einem Ultraschall-Prüfgerät. Um die Feder 3 kann eine weitere Feder 5 gelegt sein. Diese ist fest mit dem Griff 1 verbunden und wird am Sondenende durch einen Ring 7 begrenzt. Um diese Feder 5 ist ausschließlich ein Schutzschlauch 6 gelegt.The figure shows a schematic cross-section of the test probe. A spiral spring 3 is guided through the hole in the handle 1. The spring 3 is firmly connected to the component 2, which is designed as a knurled part at the end of the handle. At the end of the probe, the spring 3 is firmly connected to a support 8 of an ultrasonic transducer 9. The spring 3 encloses a connecting cable k, which is connected to a plug 10 and the ultrasonic transducer 9. The connector 10 is used to connect the probe to an ultrasonic testing device. Another spring 5 can be placed around the spring 3. This is firmly connected to the handle 1 and is limited by a ring 7 at the end of the probe. Only a protective tube 6 is placed around this spring 5.
Da das Bauteil 2 gegenüber dem Griff 1 drehbar ist, wird eine Drehbewegung mit Hilfe der Feder auf den Träger 8 des Ultraschall-Wandlers übertragen. Diese Drehbewegung kann man durch efnen geeigneten Anschlag für Bauteil 2, falls zweckmäßig, begrenzen. Am Teil 2 können Markierungen oder eine Skala angebracht werden, um die Stellung des Ultraschall-Wandlers zu kennen. Ferner kann Bauteil 2 motorisch angetrieben werden. Since the component 2 can be rotated with respect to the handle 1, a rotary movement is transmitted to the carrier 8 of the ultrasonic transducer with the aid of the spring. This rotary movement can be limited by a suitable stop for component 2, if appropriate. Markings or a scale can be attached to part 2 in order to know the position of the ultrasonic transducer. Furthermore, component 2 can be driven by a motor.
Die Anordnung gemäß der Abbildung stellt nur ein Ausführungsbeispiel dar, das sich leicht, vor allem in der äußeren Formgebung, z.B. des Griffes 1, abwandeln läßt.The arrangement according to the figure represents only one embodiment which can easily be modified, especially in terms of the external shape, for example of the handle 1.
Die Sonden gemäß der Neuerung sind nicht nur auf den Einsatz im medizinischen Boreich beschränkt. Auch in der allgemeinen Werkstoffprüfung wird man Probleme finden, die sich mit Hilfe solcher Sonden lösen lassen. Z.B. ist es möglich, in gebogeneThe probes according to the innovation are not only for use in medical Boreich limited. Problems will also be found in general materials testing that can be solved with the help of such probes. E.g. it is possible in curved

Leitungsrohre mit geringem Innendruckmesser solche Sonden einzuführen und Untersuchungen auf Materialfehler oder Messung der Wandstärke durchzuführen.Line pipes with low internal pressure gauges to introduce such probes and examinations for material defects or measurement of the Perform wall thickness.
Die Erfindung bringt auch den Vorteil, daß man mit dieser Sonde die Prüfrichtung in einer Ebene senkrecht zur Achse der Führung einhalten bzw. in der Achse drehen kann.The invention also has the advantage that you can use this probe can maintain the test direction in a plane perpendicular to the axis of the guide or rotate in the axis.
