Description
Die vorliegende rfindung betrifft eine Vorrichtung zur medizinischen Punktion und besteht da ri ii, die Beschaffenheit des Gewebes, in dem sich die Spitze der Punktionsnadel befindet, bzw. die Stärke des Einbringungsgegendruckes einer Punktbionsnadel durch mechanische, akustische, optische oder elektrische Methoden meßbar zu machen. The present invention relates to a device for medical Puncture and consists da ri ii, the texture of the tissue in which the apex is located the puncture needle is located, or the strength of the introduction counterpressure of a Puncture bion needle by mechanical, acoustic, optical or electrical methods to make measurable.
Eine Ausführungsform einer derartigen Vorrichtung zeigt, daß in der Nadel ein abgefederterBotzen steckt, der etwa mit der Spitze Ider Nadel abschneidet und dessen Stellung auf eine der beschriel>enen Arten, z. B. elektrisch, angezeigt wind. An embodiment of such a device shows that in the A spring-loaded bolt is inserted into the needle, which cuts off roughly with the point of the needle and its position in one of the described ways, e.g. B. electrically displayed wind.
Die Abbildung zeigt eine Ausführungsform der Vorrichtung in ihrem grandsätzlichen Aufbau: An die Punktionsnadel I, deren Ausführung sich von der üblichen nicht wesentlich unterscheidet, ist der abnehmbare Aufsatz 2 angeklammert. Im Aufsatz 2 ist der Bolzen 3 ben1ç-eglich angebracht. Der Bolzen 3 ist durch die Spiralfeder 4 so abgefedert, daß er in normaler Stellung etwas, z. B. 1 mm, aus der Spitze der Nadel herausragt. Wenn die Nadel 1 auf größeren Widerstand stößt, schiebt sich der Bolzen 3 zurück und die auf diesem befestigte Scheide 5 berührt den isoliert durch den Aufsatz o hindurchgefuh rten Kontakt 6. So wird ein Stromkreis geschlossen, und eine Signallampe leuchtet auf. The figure shows an embodiment of the device in its Basic structure: To the puncture needle I, the design of which differs from the usual does not differ significantly, the removable attachment 2 is clipped. In the essay 2, the bolt 3 is attached similarly. The bolt 3 is through the spiral spring 4 cushioned in such a way that in the normal position there is something, e.g. B. 1 mm, from the top of the Needle protrudes. If the needle 1 encounters greater resistance, the pushes itself Bolt 3 back and the attached sheath 5 touches the isolated through the attachment o lead through contact 6. This closes a circuit, and a signal lamp lights up.
In der Zeichnung ragt das Ende des Bolzens 7 ein wenig aus dem Aufsatz 2 heraus. Wenn sich der Bolzen zurückbewegt, tritt das Ende desselben etwas mehr hervor und zeigt so dem Operateur direkt an. wann der Gegendruck wächst. Im übrigen soll die Zeichnung nur das Wesen der Erfindung klarmachen. nicht aber Einzelheiten der Ausführung zeigen. In the drawing, the end of the bolt 7 protrudes a little from the attachment 2 out. When the bolt moves back, the end of it kicks a little more and shows it directly to the surgeon. when the back pressure increases. Furthermore the drawing is only intended to clarify the essence of the invention. but not details show the execution.
Bei der Anwendung der erfindungsgemäßen Vorrichtung zur Punktion der Markhöhle des Brustleine wird der gefederte Bolzen der Punktionsnadel hei Beginn der Punktion durch die harte äußere Knochenschicht zurückgehalten, während er bei seinem Eiintritt in die Markhöhle vorschnellt, indem er das hier befindliche lockere Markgewebe vermittels seiner Federkraft verdrängt. Bei weiterem Vorbringen der Nadel gegen die innere barte Knochenschicht der Markhöhle wird der gefederte Bolzen erneut zurückgedrängt. Bei der Punktion ändert sich also je nach der Dichte des von der Nadelspitze durchdrungenen Gewebes die Stellung des gefederten Bolzens, wobei jede Veränderung auf mechanischem, akustischem oder optischem Wege angezeigt werden kann. Bei Verwendung der erfundenen Vorrichtung wird also sicher erkannt, wann die Nadel spitze die Markhöhle erreicht hat, so daß eine versehentliche Durchbohrung der inneren Knochenschicht der Markhöhle, die zu einer schweren Gefährdung des Patienten führen kann,, mit Sicherheit vermieden wird. Bei ähnlichen in der Praxis vorkommenden Punktionen, z. B. Brustraum-, Rückenmark-, Mittelohrpunktionen, ist der Wirkungsmechanismus der gleiche. When using the device according to the invention for puncture The medullary canal of the breast leash is the spring loaded bolt of the puncture needle at the beginning while at the puncture being held back by the hard outer bone layer accelerates its entry into the medullary cavity by loosening what is here Medullary tissue displaced by means of its spring force. With further advancement of the needle the spring-loaded bolt is pressed again against the inner bare bone layer of the medullary canal pushed back. During the puncture, the of the changes depending on the density of the Needle point penetrated tissue the position of the spring loaded bolt, each Change can be indicated mechanically, acoustically or optically. When using the invented device, it is therefore reliably recognized when the needle is released tip has reached the medullary cavity, so that an accidental puncture of the inner Bone layer of the medullary cavity that pose a serious risk to the patient can, be avoided with certainty. With similar punctures occurring in practice, z. B. Chest, spinal cord, middle ear punctures, is the mechanism of action the same.
