Abstract
Description
Langgestrecktes, sondenartiges ärztliches Instrument Elongated, probe-like medical instrument
Die Erfindung betrifft ein langgestrecktes, sondenartiges ärztliches Instrument zum Einführen in Körperhöhlungen oder Durchdringen von Gewebe. Sie stellt eine Weiterbildung des Instruments dar, das durch das Hauptpatent geschützt ist.The invention relates to an elongated, probe-like medical device Instrument for insertion into body cavities or tissue penetration. She poses represents a further development of the instrument that is protected by the main patent.
Das Hauptpatent bezieht sich auf ein Endoskop mit einem angekoppelten Schwingungsgenerator, dessen Schwingungen sich bis zum distalen Ende des Endoskops ausbreiten und dessen Einführung in die Körperhöhlungen erleichtert. The main patent relates to an endoscope with an attached one Vibration generator, the vibrations of which extend to the distal end of the endoscope expand and facilitate its introduction into the body cavities.
Es hat sich nun gezeigt, daß dieses Prinzip nicht auf Endoskope beschränkt sein muß. Gemäß der vorliegenden Erfindung wird ein Schwingungsgenerator mit demselben Vorteil auch bei anderen Instrumenten der im Oberbegriff des Patentanspruchs 1 vorausgesetzten Gattung verwendet, wobei es sich sowohl um Instrumente handeln kann, die tief in Körperhöhlungen einzuführen sind, wie etwa Katheter, als auch um solche, die Gewebeschichten zu durchdringen haben, wie Kanülen. It has now been shown that this principle is not limited to endoscopes have to be. According to the present invention, a vibration generator is provided with the same The prerequisite for the preamble of claim 1 is also advantageous for other instruments Genus, which can be instruments that go deep into Body cavities to be introduced, such as catheters, as well as those that cover tissue layers like cannulas.
Damit das jeweilige Instrument nach dem Einführen in der üblichen Weise benutzbar ist und von dem Generator nicht behindert wird, ist dieser vorzugsweise lösbar mit dem Instrument verbunden, etwa durch eine Aufsteckkupplung; dies hat den weiteren Vorteil, daß in einer ärztlichen Praxis nur einer oder wenige Generatoren vorhanden zu sein brauchen, die an das jeweils benötigte Instrument angekuppelt werden und auch für andere Instrumente brauchbar sind. So that the respective instrument after insertion in the usual Can be used in a manner that is not obstructed by the generator, this is preferred releasably connected to the instrument, for example by a plug-on coupling; this has the further advantage that in a medical practice only one or a few generators need to be available, which are coupled to the required instrument and can also be used for other instruments.
Ein Ausführungsbeispiel des Gegenstandes der Erfindung wird nachstehend unter Bezugnahme auf die beigefügte Zeichnung näher erläutert, die in schematischer Schnittdarstellung einen erfindungsgemäßen Katheter darstellt. An embodiment of the subject invention is given below explained in more detail with reference to the accompanying drawing, which in schematic Shows a sectional view of a catheter according to the invention.
Der eigentliche Katheterkörper 30 trägt am proximalen Teil ein metallisches Ansatzstück 31 mit konischer Innenwandung, in die ein konisches Kupplungsstück 32 des Schwingungsgenerators eingesetzt ist; Klammern 36 in Form von Blattfedern umgreifen das Ansatzstück 31 und halten den Generator am Katheter. Der Innenaufbau des Generators ist schematisch angedeutet: Der Schwinganker 33 ist mittels einer Rückstellfeder an das Kupplungsstück 32 angelenkt und wird bei Erregung der Spule eines Elektromagneten 34 mit einem U-förmigen Joch mit Wechselstrom zu entsprechenden Schwingungen angeregt. The actual catheter body 30 carries a metallic one on the proximal part Extension piece 31 with a conical inner wall into which a conical coupling piece 32 the vibration generator is used; Clamp around clamps 36 in the form of leaf springs the extension piece 31 and hold the generator on the catheter. The internal structure of the generator is indicated schematically: The oscillating armature 33 is by means of a return spring hinged to the coupling piece 32 and is when energized the coil of an electromagnet 34 excited with a U-shaped yoke with alternating current to corresponding vibrations.
Der Generator kann mit Netzwechselstrom gespeist werden oder eine Batterie 35 enthalten, wobei die Wechselstromerzeugung in üblicher Weise erfolgt.- Der Katheter weist einen zusätzlichen seitlichen Ansatz 37 auf, der für die normalen Katheterfunktionen vorgesehen ist.The generator can be fed with mains alternating current or a Battery 35 included, the alternating current generation being carried out in the usual way. The catheter has an additional lateral extension 37 for normal Catheter functions is provided.
