Description
Bei der operativen Entfernung von Nierensteinen besteht ein arges Mißverständnis zwischen der Größe des erforderlichen Operationsschnittes und der des Steinchens. Es sind deshalb bereits mehrfach Geräte, wie z. B. Dehnungsinstrumente in Olivenform oder Steinfänger in Schlingenform, vorgeschlagen worden, um Nierensteine ohne Operation auf mechanischem Wege durch den Harnleiterzuentfernen.Die bekannten Geräte sind schwierig in der Handhabung und unsicher in der Wirkung. Sie werden deshalb von vielen Seiten abgelehnt. The surgical removal of kidney stones is bad Misunderstanding between the size of the required surgical incision and the of the stone. There are therefore already multiple devices such. B. Stretching Instruments in olive shape or stone catcher in loop shape, has been suggested to remove kidney stones Can be removed mechanically through the ureter without surgery Devices are difficult to use and unsafe to use. you will be therefore rejected from many sides.
Es wurde gefunden, daß man Nierensteine durch hochfrequente Schwingungen mechanisch zerstören kann. Bringt man einen solchen Stein z. B. unter den Einfluß eines Ultraschallgerätes, dann wird sein Gefüge so erschüttert, daß der Stein zerfällt. Diese Erkenntnis soll erfindungsgemäß zur mechanischen Beseitigung von Nierensteinen aus dem Körper ausgenutzt werden. It has been found that kidney stones can be removed by high-frequency vibrations can mechanically destroy. If you bring such a stone z. B. under the influence an ultrasound device, then its structure is shaken so that the stone crumbles. According to the invention, this finding is intended for the mechanical elimination of kidney stones be exploited from the body.
Diesem Zweck dient das den Erfindungsgegenstand bildende Gerät, dessen Eigentümlichkeit darin liegt, daß ein im wesentlichen aus einem piezoelektrischen Kristall bestehender Ultraschallerzeuger (Schallhammer) von einer zur Einführung in den Harnleiter geeigneten Kleinheit am vorderen Ende eines die Stromzuleitungen zu den Kontaktbelägen des Kristalles führenden Harnleiterkatheters angeordnet ist. Mit Hilfe des Katheters kann der Schallhammer in den Harnleiter eingeführt und bis zur schalleitenden Berührung an den im Harnleiter oder auch im Nierenkelch sitzenden Stein herangebracht werden. Der Schallhammer wird alsdann durch hochfrequenten Strom erregt. Er überträgt seine Schwingungen auf den Stein, der dadurch ganz oder so weit zertrümmert wird, daß er durch den Harnleiter abgehen kann. The device forming the subject of the invention serves this purpose The peculiarity lies in the fact that one essentially consists of a piezoelectric Crystal existing ultrasonic generator (sonic hammer) from one to the introduction in the ureter suitable smallness at the front end of one of the power supply lines is arranged to the contact coatings of the crystal leading ureteral catheter. With the help of the catheter, the sonic hammer can be inserted into the ureter and up for sound-conducting contact with those sitting in the ureter or in the kidney calyx Stone to be brought up. The sonic hammer is then powered by high-frequency electricity excited. He transfers his vibrations to the stone, which thereby completely or so is shattered so far that it can come off through the ureter.
Der Schallhammer ist vorzugsweise an seiner vorderen Stirnfläche halbei- oder halbkugelförmig oder ähnlich gewölbt. Dadurch wird eine wirksame Berührung mit dem zu zertrümmernden Stein begünstigt, während zugleich die Einführung des Gerätes erleichtert wird. The sonic hammer is preferably on its front face semi-spherical or hemispherical or similarly arched. This creates an effective touch favored with the stone to be smashed, while at the same time introducing the Device is facilitated.
In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes in einfachen Strichen dargestellt. The drawing shows an embodiment of the subject matter of the invention shown in single lines.
Ein Harnleiterkatheter I bekannter Art ist am vorderen Ende erweitert und enthält in seiner Erweiterung 2 einen kleinen Ultraschallerzeuger oder Schallhammer. A ureteral catheter I of known type is expanded at the front end and in its extension 2 contains a small ultrasonic generator or sonic hammer.
Dieser besteht aus einem nach bekannten Regeln geschnittenen Quarzkörper 3, der vorn und hinten einen Kontaktbelag 4, 5 hat. Der Durchmesser des im Querschnitt vorzugsweise kreisrunden Schallhammers ist so klein gewählt, daß er sich in den Harnleiter einführen läßt. Zweckmäßig kann sein Durchmesser etwa 4 bis 5 mm betragen. Die vordere Kontaktplatte 4 des Schallhammers ist an ihrer Stirnfläche etwa halbeiförmig oder ähnlich gewölbt und ragt aus der Erweiterung des Katheters heraus.This consists of a quartz body cut according to known rules 3, which has a contact surface 4, 5 at the front and rear. The diameter of the in cross section preferably circular sound hammer is chosen so small that it is in the Ureter can be inserted. Appropriately, its diameter can be about 4 to 5 mm. The front contact plate 4 of the sound hammer is approximately half-oval on its end face or similarly curved and protrudes from the extension of the catheter.
Mit den beiden Kontaktbelägen sind zwei isolierte Leitungen 6, 7 verbunden, die durch den Katheter I hindurchlaufen und zu einem Hochfrequenzstromerzeuger 8 geführt sind. Der Stromerzeuger 8 ist hinsichtlich der Stromfrequenz regelbar, so daß durch seine Regelung die Schwingungszahl des Schallhammers auf den jeweils günstigsten Wert eingestellt werden kann. Two insulated lines 6, 7 are connected to the two contact surfaces connected, which pass through the catheter I and to a high frequency generator 8 are performed. The power generator 8 can be regulated with regard to the power frequency, so that by its regulation the number of vibrations of the sound hammer on each the most favorable value can be set.
In der Zeichnung ist gezeigt, wie der Schallhammer 3 bis 5 mittels des Katheters I an einen im Harnleiter g sitzenden Nierenstein IO herangebracht werden kann. In the drawing it is shown how the sonic hammer 3 to 5 means of the catheter I brought up to a kidney stone IO sitting in the ureter g can be.
Natürlich beschränkt sich die Erfindung nicht auf das beschriebene Beispiel, vielmehr sind Abänderungen desselben sowie andere Ausführungen möglich. So könnte die vordere Kontaktplatte selbst eben und an ihr ein besonderer halbeiförmiger, halbkugeliger oder ähnlich gestalteter Schlagkörper befestigt sein. Gegebenenfalls könnte die Übertragung der Schwingungen vom Schallhammer auf den zu zertrümmernden Stein auch mittels einer Flüssigkeit erfolgen, indem vorn am Schallhammer ein durch eine biegsame Membran abgeschlossener, mit einer Flüssigkeit, wie Glycerin, gefüllter Hohlraum angeordnet ist. Der Schallhammer wird dann mit der Membran an den zu beseitigenden Stein angedrückt. An Stelle von Quarz könnte auch ein anderes piezoelektrischer Kristall verwendet werden. pATENTANSPRVCllE: I. Gerät zur Beseitigung von Nierensteinen, gekennzeichnet durch einen im wesentlichen aus einem piezoelektrischen Kristall, insbesondere Quarz, bestehenden Ultraschallerzeuger (Schallhammer) von einer zur Einführung in den Harnleiter geeigneten Kleinheit, der am vorderen Ende eines die Stromzuleitungen zu den Kontaktbelägen des Kristalles führenden Harnleiterkatheters angebracht ist. Of course, the invention is not limited to what has been described Example, rather modifications of the same and other designs are possible. So the front contact plate itself could be flat and on it a special half-oval, hemispherical or similarly designed impactor be attached. Possibly could be the transmission of the vibrations from the sonic hammer to the one to be smashed Stone can also be done by means of a liquid by putting a through the front of the sonic hammer a flexible membrane closed off, filled with a liquid such as glycerine Is arranged cavity. The sonic hammer is then attached to the membrane to be eliminated Stone pressed. Instead of quartz, another piezoelectric could also be used Crystal can be used. PATENT APPLICATION: I. Device for the removal of kidney stones, characterized by a substantially composed of a piezoelectric crystal, in particular quartz, existing ultrasonic generator (sonic hammer) from one to the Introducing the ureter suitable smallness, which is at the front end of one of the Power supply lines to the contact surfaces of the crystal leading ureteral catheter is appropriate.
