  Vorrichtung zur Spreizfederung der Schenkel von chirurgischen Instrumenten. 



   Vorliegende Erfindung betrifft die Fcderungsvorrichtung für Zangen und zangenartig zu handhabende Werkzeuge, welche namentlich auch für chirurgische Geräte mit scherenartiger 
 EMI1.1 
 dem Handgriffdruck in die Spreizlage auseinanderfedern zu lassen, werden meist Blattfedern angewendet, deren eines Ende an dem einen Schenkel lösbar befestigt ist und deren anderes freies Abspreizende inwendig am anderen Griffschenkel gleiten kann. Durch Rollenkontakt hat man hier ausserdem die Gleitung sanfter zu machen versucht. Indessen hat diese Vorrichtung immerhin den Nachteil, dass die betreffende Gleitstelle am Schenkel stark abgenützt wird und eine Reibstelle erzeugt, wodurch sich ein ungleichmässiges, manchmal ruckweises   Vorbeigleiteh beim   Schliessen wie beim   Öffnen der Lange   ergibt.

   Ausserdem wird die Politur des Metalls an solcher   Rpibuilgsstel1e   zerstört und es entstehen Vertiefungen, an denen sich Unreinigkeiten ansammeln und festsetzen können. Um insbesondere bei chirurgischen Zangen und dergleichen Instrumenten diesen Mangel zu beseitigen, besteht die vorliegende Erfindung in der Anordnung eines Verbindungsgliedes zwischen dem freien Federende und dem anderen Schenkel der Zange. wobei das Glied die Form eines lösbaren   gelenkigen Bügels.   der eng an den   Zargenschenkel   heranklappbar ist, besitzt. 



   Auf der Zeichnung ist Fig. 1 die Ansicht einer chirurgischen (Exstirpations-) Zange mit durch die Federung   auseinandergespreizten Schenkeln   ;   Fig.   zeigt die Schenkel entgegen   der Federung zusammengedrückt   und Fig. 3 zeigt die Einzelansicht des   bügelförmigen   Verbindungsgliedes nebst der Feder, wobei der Zangenschenkel nach der Linie A--B, von Fig.   l   geschnitten ist.

   PATENT-ANSPRÜCHE :
1. Vorrichtung zur Spreizfederung der Schenkel von chirurgischen Instrumenten, insbesondere Zangen, mit gelenkigem   Verbindungsgliede   zwischen dem einen Schenkel und dem Federende, dadurch gekennzeichnet, dass das Verbindungsglied, welches an dem zugehörigen Schenkel drehbar ist. bügelförmig gestaltet ist und mittels Gelenklagereingriffs mit dem Federende zusammenschliesst.

  Device for expanding the legs of surgical instruments.



   The present invention relates to the conveying device for pliers and tools to be handled like pliers, which are also especially suitable for surgical devices with scissors-like
 EMI1.1
 To allow the handle pressure to spring apart into the spread position, leaf springs are mostly used, one end of which is releasably attached to one leg and the other free spreader end can slide inside on the other handle leg. In addition, an attempt has been made to make the gliding smoother through roller contact. However, this device has the disadvantage that the sliding point in question on the leg is heavily worn and creates a friction point, which results in an uneven, sometimes jerky gliding past when closing as when opening the length.

   In addition, the polish of the metal is destroyed at such an attachment point and depressions are created in which impurities can collect and stick. In order to overcome this deficiency, particularly in surgical forceps and similar instruments, the present invention consists in the arrangement of a connecting member between the free spring end and the other leg of the forceps. the member being in the form of a releasable articulated bracket. which can be folded up close to the frame leg.



   In the drawing, FIG. 1 is a view of surgical (extirpation) forceps with the legs spread apart by the suspension; FIG. 3 shows the legs compressed against the suspension, and FIG. 3 shows the individual view of the bow-shaped connecting member together with the spring, the pliers leg being cut along the line A - B of FIG.

 accomplish; any replacement that may be required can also be easily carried out.



   PATENT CLAIMS:
1. A device for expanding the legs of surgical instruments, in particular pliers, with articulated connecting members between the one leg and the spring end, characterized in that the connecting member, which is rotatable on the associated leg. Is bow-shaped and connects to the spring end by means of pivot bearing engagement.
