Description

Translated fromGerman

Die vorliegende rfindung betrifft eine Vorrichtung zur medizinischenPunktion und besteht da ri ii, die Beschaffenheit des Gewebes, in dem sich die Spitzeder Punktionsnadel befindet, bzw. die Stärke des Einbringungsgegendruckes einerPunktbionsnadel durch mechanische, akustische, optische oder elektrische Methodenmeßbar zu machen. The present invention relates to a device for medicalPuncture and consists da ri ii, the texture of the tissue in which the apex is locatedthe puncture needle is located, or the strength of the introduction counterpressure of aPuncture bion needle by mechanical, acoustic, optical or electrical methodsto make measurable.

Eine Ausführungsform einer derartigen Vorrichtung zeigt, daß in derNadel ein abgefederterBotzen steckt, der etwa mit der Spitze Ider Nadel abschneidetund dessen Stellung auf eine der beschriel>enen Arten, z. B. elektrisch, angezeigtwind. An embodiment of such a device shows that in theA spring-loaded bolt is inserted into the needle, which cuts off roughly with the point of the needleand its position in one of the described ways, e.g. B. electrically displayedwind.

Die Abbildung zeigt eine Ausführungsform der Vorrichtung in ihremgrandsätzlichen Aufbau: An die Punktionsnadel I, deren Ausführung sich von der üblichennicht wesentlich unterscheidet, ist der abnehmbare Aufsatz 2 angeklammert. Im Aufsatz2 ist der Bolzen 3 ben1ç-eglich angebracht. Der Bolzen 3 ist durch die Spiralfeder4 so abgefedert, daß er in normaler Stellung etwas, z. B. 1 mm, aus der Spitze derNadel herausragt. Wenn die Nadel 1 auf größeren Widerstand stößt, schiebt sich derBolzen 3 zurück und die auf diesem befestigte Scheide 5 berührt den isoliert durchden 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 itsBasic structure: To the puncture needle I, the design of which differs from the usualdoes not differ significantly, the removable attachment 2 is clipped. In the essay2, the bolt 3 is attached similarly. The bolt 3 is through the spiral spring4 cushioned in such a way that in the normal position there is something, e.g. B. 1 mm, from the top of theNeedle protrudes. If the needle 1 encounters greater resistance, the pushes itselfBolt 3 back and the attached sheath 5 touches the isolated throughthe 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 Aufsatz2 heraus. Wenn sich der Bolzen zurückbewegt, tritt das Ende desselben etwas mehrhervor und zeigt so dem Operateur direkt an. wann der Gegendruck wächst. Im übrigensoll die Zeichnung nur das Wesen der Erfindung klarmachen. nicht aber Einzelheitender Ausführung zeigen. In the drawing, the end of the bolt 7 protrudes a little from the attachment2 out. When the bolt moves back, the end of it kicks a little moreand shows it directly to the surgeon. when the back pressure increases. Furthermorethe drawing is only intended to clarify the essence of the invention. but not detailsshow the execution.

Bei der Anwendung der erfindungsgemäßen Vorrichtung zur Punktionder Markhöhle des Brustleine wird der gefederte Bolzen der Punktionsnadel hei Beginnder Punktion durch die harte äußere Knochenschicht zurückgehalten, während er beiseinem Eiintritt in die Markhöhle vorschnellt, indem er das hier befindliche lockereMarkgewebe vermittels seiner Federkraft verdrängt. Bei weiterem Vorbringen der Nadelgegen die innere barte Knochenschicht der Markhöhle wird der gefederte Bolzen erneutzurückgedrängt. Bei der Punktion ändert sich also je nach der Dichte des von derNadelspitze durchdrungenen Gewebes die Stellung des gefederten Bolzens, wobei jedeVeränderung auf mechanischem, akustischem oder optischem Wege angezeigt werden kann.Bei Verwendung der erfundenen Vorrichtung wird also sicher erkannt, wann die Nadelspitze die Markhöhle erreicht hat, so daß eine versehentliche Durchbohrung der innerenKnochenschicht der Markhöhle, die zu einer schweren Gefährdung des Patienten führenkann,, mit Sicherheit vermieden wird. Bei ähnlichen in der Praxis vorkommenden Punktionen,z. B. Brustraum-, Rückenmark-, Mittelohrpunktionen, ist der Wirkungsmechanismusder gleiche. When using the device according to the invention for punctureThe medullary canal of the breast leash is the spring loaded bolt of the puncture needle at the beginningwhile at the puncture being held back by the hard outer bone layeraccelerates its entry into the medullary cavity by loosening what is hereMedullary tissue displaced by means of its spring force. With further advancement of the needlethe spring-loaded bolt is pressed again against the inner bare bone layer of the medullary canalpushed back. During the puncture, the of the changes depending on the density of theNeedle point penetrated tissue the position of the spring loaded bolt, eachChange can be indicated mechanically, acoustically or optically.When using the invented device, it is therefore reliably recognized when the needle is releasedtip has reached the medullary cavity, so that an accidental puncture of the innerBone layer of the medullary cavity that pose a serious risk to the patientcan, be avoided with certainty. With similar punctures occurring in practice,z. B. Chest, spinal cord, middle ear punctures, is the mechanism of actionthe same.
