Abstract
Description
Die Erfindung betrifft eine Kupplung für eine Kryosonde mit einem doppellumigen Sondenschaft, einem dessen oberen Bereich umfassenden zylindrischen Sondenteil und einem zylindrischen Anschlussteil.The invention relates to a clutch for a cryoprobe with a double-lumen probe shaft, one of its upper area comprising cylindrical probe part and a cylindrical connecting part.
Kryosonden werden in der Medizin zum Applizieren von Kälte an einen Ort, etwa zum Zerstören von Tumorgewebe oder in der Schmerztherapie, eingesetzt. Sie bestehen aus einem doppellumigen Sondenschaft, einem dessen oberen Bereich umfassenden zylindrischen Steckerteil und einem von einem Griff ausgebildeten zylindrischen Buchsenteil.Cryoprobes are used in medicine for applying cold to a place, for example to destroy Tumor tissue or used in pain therapy. They exist from a double-lumen probe shaft, one of its upper area comprehensive cylindrical plug part and one of a handle trained cylindrical socket part.
Eine Kupplung der eingangs genannten
Art ist bereits aus der
Der Nachteil dieser Art Kupplung ist, dass die Kupplung der Kryosonde vom Benutzer eine aufmerksame Handhabung verlangt. Beispielsweise ist es bei einem während einer Operation durchzuführenden Wechsel der Kryosonde unerlässlich, darauf zu achten, dass das Steckteil und das Buchsenteil richtig zueinander orientiert sind und die Überwurfmutter richtig fixiert ist.The disadvantage of this type of clutch is that the coupling of the cryoprobe by the user is an attentive Handling requires. For example, one is during one Operation to be performed Exchange of the cryoprobe is essential make sure that the male part and the female part are correct are oriented towards each other and the union nut is properly fixed is.
Aufgabe der Erfindung ist es deshalb, eine Kupplung für eine Krysonde bereitzustellen, die eine einfache Handhabung ermöglicht.The object of the invention is therefore a clutch for to provide a cryoprobe that enables easy handling.
Die Erfindung wird gelöst durch eine Kupplung für eine Kryosonde, mit einem doppellumigen Sondenschaft, einem dessen oberen Bereich umfassenden zylindrischen Sondenteil mit einer mit dem äußeren Lumen des Sondenschafts kommunizierenden Kammer und einem konzentrisch verlaufenden, das obere Ende des Sondenschafts aufnehmenden Nippel und einem zylindrischen Anschlussteil mit einer konzentrisch angeordneten Nippelaufnahme mit einer Öffnung, die einen die Öffnung verschließenden, im verbundenen Zustand der Kupplung gegen die Kraft einer Druckfeder von dem Nippel wegdrückten und die Öffnung freigebenden Schließkörper aufweist und im mit dem Sondenteil verbundenen Zustand mit dem inneren Lumen des Sondenschafts zum Einleiten des Kühlmittels kommuniziert, wobei das Anschlussteil ein konzentrisches Innengewinde und das Sondenteil ein mit dem Innengewinde schraubendes Außengewinde zum Verbinden des Sondenteils mit dem Anschlussteil aufweist und eine Wandung der Kammer des Sondenteils mit einer Abgasöffnung versehen ist, die im verbundenen Zustand mit einem im Anschlussteil angeordneten Rohr zum Ableiten des Kältemittels kommuniziert.The invention is solved by a clutch for a cryoprobe, with a double-lumen probe shaft, one of which cylindrical probe part comprising an upper region with a the outer lumen of the specialty communicating chamber and one concentric extending nipple receiving the upper end of the probe shaft and a cylindrical connecting part with a concentrically arranged Nipple holder with an opening, some the opening occlusive, in the connected state of the coupling against the force of a compression spring pushing away from the nipple and the opening has releasing closing body and in the state connected to the probe part with the inner lumen of the probe shaft for introducing the coolant communicates, the Connection part a concentric internal thread and the probe part an external thread screwing with the internal thread for connecting the probe part with the connecting part and a wall of the chamber of the probe part with an exhaust opening is provided in the connected state with a in the connector arranged pipe communicates for draining the refrigerant.
Die Erfindung wir im Folgenden anhand von Zeichnungen näher erläutert. Es zeigen:The invention is based on the following of drawings closer explained. Show it:
