Description

Stand der TechnikState of the art

Derzeit werden in der acetabulären Versorgung durch zementierte Polyethylenpfannen diese Pfanen während des Zementierens durch manuelles Pressen mittels eines herkömmlicher Pfannenpresser die Pfanne in das Zementbett gepreßt. Die dadurch entstehenden Mikrobewegungen seitens der Atmung durch den ausführenden Chirurgen, kommt es zu nicht ganz 100%-igem Formschluß und Verbindung zwischen Zement und Pfanne.Currently, in acetabular treatment using cemented polyethylene cups, these cups are pressed into the cement bed by manual pressing using a conventional cup press during cementing. The resulting micro-movements from the breathing of the surgeon result in a less than 100% form fit and connection between the cement and the cup.

Problemproblem

Der im Schutzanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, einen automatischen Pfannenpresser zu schaffen, der ohne ständiges manuelles Dazutun einen konstanten bewegungsfreien Preßdruck auf die im Zementbett liegende Pfanne während der Aushärtungsphase ausübt.The invention specified in claim 1 is based on the problem of creating an automatic pan press which, without constant manual intervention, exerts a constant, movement-free pressing pressure on the pan lying in the cement bed during the hardening phase.

LösungSolution

Dieses Problem wird mit den in Schutzanspruch 1 aufgeführten Merkmalen gelöst.This problem is solved with the features listed in claim 1.

Erreichte Vorteile:Benefits achieved:

Mit der Erfindung wird erreicht, daß das Zementieren einer Polyethylenpfanne sicherer und zeitsparender wird.The invention makes cementing a polyethylene cup safer and more time-saving.

Weitere Ausgestaltung der ErfindungFurther development of the invention

Eine vorteüehafte Ausgestaltung der Erfindung stellt sich dar durch die Verwendung des im Fig. (1) und (2) abgebildeten Nagels (3), der intraoperativ einen Wundhakenhalter ersetzt. Ferner ist es möglich mittels dieses Instrumentes die OP-Zeit um ca. 8 Min. zu verkürzen, was auch eine Kostenersparnis mit sich bringt.An advantageous embodiment of the invention is represented by the use of the nail (3) shown in Fig. (1) and (2), which replaces a retractor holder intraoperatively. Furthermore, it is possible to shorten the operating time by approx. 8 minutes using this instrument, which also results in cost savings.

Beschreibung eines oder mehrerer AusführungsbeispieleDescription of one or more embodiments

Ein Ausführungs- und Verwendungsbeispiel wird in Fig. (2) gezeigt, wie im Schutzanspruch 1 Abs. 2 detailliert beschrieben.An embodiment and use example is shown in Fig. (2), as described in detail in claim 1, paragraph 2.

Claims (2)

A SchutzansprücheA Protection claims 1. Anatomisches Pfannenpreßinstrument zum konstanten Pressen, 1 . Anatomical cup pressing instrument for constant pressing, dadurch gekennzeichnet,characterized, daß das Instrument durch die Kugel (1) einen gleichmäßigen Druck auf die im Knochenzement liegende Polyethylenpfanne (7), ohne manuelles Dazutun, ausübt.that the instrument exerts a uniform pressure on the polyethylene cup (7) lying in the bone cement through the ball (1) without manual intervention. 2. Pfannenpreßinstrument nach S chutzanspruch (1)2. Cup pressing instrument according to claim (1) dadurch gekennzeichet,characterized by daß das Instrument den Nagel (3), die Drahtschlaufe (4) den Haltebügel (2) und die Gewindespindel (6) auf Preßdruck gebracht wird. Durch Verwendung von Kugeln unterschiedlicher Durchmesser sind alle gängigen Polyethylenpfanneninnendurchmesser zu bedienen z.B. 32 mm, 28 mm, 24 mm usw.that the instrument is applied to the nail (3), the wire loop (4), the retaining bracket (2) and the threaded spindle (6). By using balls of different diameters, all common polyethylene cup inner diameters can be used, e.g. 32 mm, 28 mm, 24 mm, etc.
