Abstract

The device provided to limit the pressure applied to the head of the foetus is a knurled head screw (3) which can be adjusted to regulate the pressure. A centrally located pin is fixed rigidly to a lug and inserted in an eyelet open on one side only, thus holding both forcep arms (1, 2) securely together whilst permitting rapid simultaneous opening and closing of the forceps. The forceps can be easily modified using a ratchet lock system to fix the arms in a required position. The forceps can be easily manipulated and are simple to sterilize.

Description

Geburtszangenme chani smus Die Erfindung betrifft eine Zusatzanmeldung zur Patentanmeldung P 24 54 762,4 zum Zwecke der Geburtshilfe.Obstetrical forceps me chani smus 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 vorzugsweise mittels einer Schraube ( hier eine Rändelschraube ) erfolgen, indem die an den Kopf des Kindes angelegtalund vorzugsweise mittig verankerten Zangenteile durch Drehung der Schraube den Abstand der beiden Zangenlöffel verstellen und fixieren können. Außer Zugkräften beim Entwickeln des Fötus können auf den Kopf desselben keine Kräfte mehr wirken.The pressure limitation according to the invention on the pliers can preferably by means of a screw (here a knurled screw) by attaching the to the head of the child and preferably centrally anchored parts of the forceps by turning adjust and fix the distance between the two tong spoons using the screw. Except for tensile forces in the development of the fetus, no forces can exert on the head of the same work more.

Die Zangenteile werden einzeln um den Kopf des Fötus gelegt und vorzugsweise mittig mittels einer dafür vorgesehenen Verankerungsmöglichkeit miteinander verbunden. Die Verbindung muß so sein, daß die Zangenteile schnell zusammengebracht aber auch wieder getrennt werden können, was vorzugsweise verschiedene Modifizie#rungen von Stift/Ösen - Verbindungen gewährleisten.The forceps parts are placed around the head of the fetus and preferably one at a time connected to one another in the middle by means of an anchoring option provided for this purpose. The connection must be such that the pliers parts are quickly brought together but also can be separated again, which is preferably different modifications of Ensure pin / eyelet connections.

Diese einfache Lösung erfüllt die Forderung nach einfacher Handhabung und leichter Sterilisierbarkeit.This simple solution meets the requirement for simple handling and easy to sterilize.

Der erfindungsgemäße Geburtszangenmechanismusvin einem Ausführungsbeispiel Fig.1 in einer Draufsicht a und einem Schnitt nach der Linie A-A in einer Seitansicht b dargestellt.The forceps mechanism according to the invention in one embodiment 1 in a plan view a and a section along the line A-A in a side view b shown.

In Fig.1 sind mit 1 und 2 die beiden Zangenteile bezeichnet.In Figure 1, 1 and 2, the two pliers parts are designated.

Mit einer Rändelschraube 3 wird der Anpreßdruck der Zangenteile 1 und 2 auf den Kopf des Fötus begrenzt. Die Griffteile 4 ermöglichen ein einfaches Entwickeln des Kindes.With a knurled screw 3, the contact pressure of the pliers parts 1 and 2 limited to the head of the fetus. The handle parts 4 allow a simple Developing the child.

Mit 5 wird ein Stift bezeichnet, der mit einer Nase 6 fest verbunden und in z,B, einseitig geöffnete Ösen 7 eingelegt, die beiden Zangenteile zusammenhält und gleichzeitig schnelles öffnen und schließen der Geburtszange ermöglicht, Dies kann in ähnlicher Art und Weise beliebig modifiziert werden, z.B. durch einfaches Verhaken der beiden Zangenteile 1 und 2 durch ein Widerlager im einen und hakenförmiges Teil im anderen Zangenteil.5 designates a pin which is firmly connected to a nose 6 and in z, B, eyelets 7 open on one side, which hold the two parts of the pliers together and at the same time enables rapid opening and closing of the forceps, this can be modified as required in a similar way, e.g. by simply Hooking of the two pliers parts 1 and 2 by an abutment in one and hook-shaped Part in the other pliers part.
