  • [0001] [0001]
    Die Erfindung betrifft eine Zange der im Oberbegriff des Anspruch 1 genannten Art. The invention relates to a pliers referred to in the preamble of claim 1.
  • [0002] [0002]
    Gattungsgemäße Zangen sind zu Reinigungszwecken mehrteilig zerlegbar, wobei insbesondere der Zangenkopf vom Schaftrohr abkuppelbar ist. Generic Pliers are several parts dismantled for cleaning purposes, in particular the Head of pliers from the shaft tube can be uncoupled. Üblicherweise ist dabei auch noch das Schaftrohr vom Handhabungsteil mit den Betätigungsgriffen abkuppelbar. Usually, it is also totally the shaft tube by manipulating member with the operating handles uncoupled. Die Bajonettverbindung bildet dabei, wenn der Stift in Kupplungsstellung im Querschlitz steht, die Zugverbindung zwischen Zangenkopf und Schaftteil. The bayonet connection forms when the pin is in the coupling position in the transverse slot, the rail link between the pliers head and shank portion.
  • [0003] [0003]
    Bei bekannten Bajonettkonstruktionen ist eine zusätzliche Drehsicherung erforderlich, die außerhalb der Bajonettverbindung eine Drehsicherung zwischen Zangenkopf und Schaftrohr ergibt. In known bayonet constructions, an additional rotation is required, which results in a rotation between the tongs head and the shaft tube outside of the bayonet connection. Dadurch wird vermieden, daß bei Drehbewegungen mit der Zange sich der Zangenkopf gegenüber dem Schaftrohr dreht und der Stift außer Eingriff mit dem Querschlitz gelangt. This avoids that, when rotational movements with the pliers, the pliers head pipe rotates relative to the shaft and the pin is disengaged from the transverse slot. Das könnte zum Abfallen des Zangenkopfes im Patienten führen, was erhebliche nachteilige Folgen hätte. This could lead to the fall of the pliers head in patients, which have significant adverse consequences.
  • [0004] [0004]

Bei der Bekannten Konstruktion ist eine zusätzliche Drehsicherung am proximalen Ende der Zugstange vorgesehen, die die Schließbewegung der Zange steuert und vom Zangenkopf ausgehend das Schaftrohr bis zu einem Handhabungsteil am proximalen Ende durchläuft. In the known construction, an additional rotation to the proximal end of the pull rod is provided, which controls the closing movement of the pincers and starting the steerer tube passes through the pliers head to a handle member at the proximal end.

    Aus anderen technischen Gebieten sind Bajonettverbindungen mit integrierter Drehsicherung bekannt, die am Ende des Querschlitzes einen parallel zum Längsschlitz laufenden Sackschlitz und eine in Achsrichtung wirkende Rückhaltefeder aufweist. From other technical fields bayonet connections with integrated anti-rotation are known, which has a longitudinal slot running parallel to the blind slot and a force acting in the axial direction retaining spring at the end of the transverse slot. Versuche, diese Konstruktion auf dem Gebiet medizinischer Zangen einzusetzen, scheiterten an den beengten Platzverhältnissen und insbesonere an den Reinigungsanforderungen. Attempts to use this structure in the field of medical forceps, failed due to the limited space and insbesonere to the cleaning requirements.
  • [0006] [0006]
    Die Aufgabe der vorliegenden Erfindung besteht darin, eine gattungsgemäße Zange mit verbesserter Drehsicherung zu schaffen. The object of the present invention is to provide a generic tool with improved rotation.
  • [0007] [0007]
    Diese Aufgabe wird mit dem Merkmal des Anspruches 1 gelöst. This object is achieved by the feature of claim 1.
  • [0008] [0008]
    Erfindungsgemäß ist der Querschlitz des Bajonetts mit einem federnden Seitenrand und einer Nase an einem Seitenrand ausgebildet. According to the invention the transverse slot of the bayonet is formed with a resilient side edge and a tab on a side edge. Wenn durch entsprechende Verdrehung des Zangenkopfes gegenüber dem Schaftrohr der Stift in den Querschlitz gedrückt wird, so kann er an der seine Weiterbewegung versperrenden Nase vorbei gelangen, indem er den federnden Seitenrand zur Seite drückt. When the pin is pressed into the transverse slot by corresponding rotation of the pliers head relative to the shaft tube so it can at its further movement obstructing nasal get past by pressing the resilient side edge to the side. Der Stift rastet dann hinter der Nase ein und ist durch den rückfedernden Seitenrand und die Nase gegen Rückbewegung im Querschlitz gesichert. The pin then engages behind the nose and is secured by the spring-back side edge and the nose to return movement in the transverse slot. Dadurch ergibt sich eine wirkungsvolle Drehsicherung, die den Bajonetteingriff auch bei auf den Zangenkopf einwirkenden Drehkräften sichert. This results in an effective rotation that secures the bayonet engagement even when acting on the pliers head rotational forces. Ist die Federwirkung des Seitenrandes ausreichend stark, so kann auf die zusätzliche Drehsicherung am proximalen Ende der Betätigungsstange verzichtet werden. If the spring action of the lateral edge of sufficient strength can be dispensed to the additional rotation at the proximal end of the actuating rod. Wird diese aus Sicherheitsgründen beibehalten, so dient die erfindungsgemäße Drehsicherung zumindest der verliersicheren Halterung des Zangenkopfes am Schaftrohr, solange diese beiden Teile in verriegelter Stellung gehandhabt werden und die endgültige Drehsicherung am proximalen Ende der Zugstange noch nicht hergestellt ist. This is maintained for safety reasons, so the rotation lock of the present invention serves at least the captive mounting of the tong head at the shaft tube, as long as these two parts are handled in the locked position and the final rotation at the proximal end of the pull rod is not yet prepared. Es ergibt sich also eine Sicherung für die Handhabung der teilweise demontierten Zange. Accordingly, there is a backup for the handling of the partially disassembled pliers.

    Vorteilhaft ist der federnde Bereich des Querschlitzes gemäß Anspruch 2 als Federzunge ausgebildet. The resilient region of the transverse slot is advantageously embodied according to claim 2 as a spring tongue. Dabei sind vorteilhaft die Merkmale des Anspruches 3 vorgesehen, wonach die Federzuge integral aus dem Material der Hülse frei geschnitten ist. The features of claim 3 are advantageously provided that the spring part is integrally cut free from the material of the sleeve. Es ergibt sich eine technisch sehr einfache Konstruktion, die verschiedene vorteilhafte Ausführungsvarianten ermöglicht. The result is a technically very simple construction which allows various advantageous embodiments.
