Abstract

The obstetrical forceps are equipped with a device limiting the angle opening of the forcep arms and the contact pressure made on the infant's head. Pref. these parametes are controlled by use of a sliding par displaced axially into the notches of one of forcep parts. The forcep arms (1, 2) are pivoted together using a pin (3) pressed into one part (1) and an aperture in the other arm (1). The sliding part (5) slides axially in relation to the forceps and has a sharp angled surface milled into the forcep arm (2) so that when the part slides along the angled surface the angle of opening is varied.

Description

Geburtssangenmechanismus Die Erfindung betrifft eine Zusatzanmeldung zur Patentanmeldung P 24 54 762.4 zum Zwecke der Geburtshilfe.Conger Mechanism The invention relates to an additional application for patent application P 24 54 762.4 for the purpose of obstetrics.

Die erfindungsgemäße Druckbegrenzung an der Zange kann vorteilhaft mittels eines Schiebers erfolgen, der im einen Zangenteil untergebracht ist und einer schiefen Ebene im anderen Teil der Zange. Bei verschieben des Schiebeteiles ändert sich der Üffnungswinkel der Zange. Die Zange ist derart ausgebildet, daß der rechte Zangenarm als erster, danach der linke Zangenarm eingelegt wird, wobei gewa~hrleistet sein muß, daß beim Zusammenlegen der Zangenarme der größte Öffnungswinkel der Zange erreicht wird und erst nachdem diese miteinander verbunden sind der Anpreßdruck mittels des besagten Schiebeteils verändert wird. Aufspringen oder weiteres Zusammendrücken der Zangenarme ist nach einer Einstellung mit dem Schiebeteil nicht mehr möglich ohne verstellen des Schiebeteils. Damit ist eine otimale Sicherheit in Bezug auf Schädeldeformationen, Abrutschen der Zange und ähnliches erreicht und eine wesentliche einfachere Bedienbarkeit gewährleistet. Bei der Form der Zangenlöffel kann auf herkömmliche Formen zurückgegriffen werden.The pressure limitation according to the invention on the pliers can be advantageous take place by means of a slide, which is housed in a pliers part and an inclined plane in the other part of the pliers. When moving the sliding part the opening angle of the pliers changes. The pliers are designed such that the right tong arm is inserted first, then the left tong arm, whereby It must be ensured that the largest opening angle when the tong arms are folded together the pliers is reached and only after they are connected to each other the contact pressure is changed by means of said sliding part. Jump open or squeeze further the tong arm is no longer possible after an adjustment with the sliding part without adjusting the sliding part. This is an optimal security in terms of Skull deformations, slipping of the forceps and the like achieved and a substantial Easier usability guaranteed. The shape of the tong spoon can be based on conventional Forms can be used.

Der erfindungsgemäße Geburtszangenmechanismus ist im Ausführungs beispiel Fig. 1 in einer Draufsicht dargestellt, Teil 1 und 2 zeigen den rechten und linken Zangenteil, die mittels eines Stiftes 3, der im rechten Zangenteil 1 eingepreßt ist und einer Bohrung im Zangenteil 2 miteinander drehbar verbunden werden können, Teil 5 ist das Schiebeteil, das in Zangenaxialer Richtung verschiebbar ist und in Ausfräsungen geführt wird. Im Zangenteil 2 ist eine schiefe Ebene eingefräst, damit der Schiebeteil5 - auf dieser schiefen Ebene verschoben- den Öffnungswinkel der Zangenarme verändert.The forceps mechanism according to the invention is in the execution example Fig. 1 shown in a plan view, parts 1 and 2 show the right and left Pliers part, which is pressed into the right pliers part 1 by means of a pin 3 and a hole in the pliers part 2 can be rotatably connected to one another, Part 5 is the sliding part, which is slidable in the pincer axial direction and in Milling is performed. In the pliers part 2 an inclined plane is milled so the sliding part5 - shifted on this inclined plane- the opening angle of the Pincer arms changed.
