Abstract

The guide consists of a plate (A) with a series of apertures (1) to receive guide pins (B) which locate and guide the cannular bone screws. The orifices are separated by a constant distance (2) which is the same as the separation of the orifices of the final osteosynthesis plate. One end of the plate includes a projection (5) with an additional orifice (4) which receives a further pin (B') for locating the guide plate correctly. A projection (3) formed at the same end of the plate receives an instrument manipulating handle (C) by a screw fit.

Description

GUIDE BROCHES POUR OSTEOSYNTHESE DES FRACTURES
EPIPHYSO-METAPHYSAIRES PAR PLAQUE VISSE PREFORMEE
Le dispositif présenté vise à faciliter l'ostéosynthèse par plaques dites "anatomiques" utilisées pour les fractures des extrémités osseuses au moyen de vis canulées guidées par broches. Avant de placer une plaque contre l'extrémité osseuse reconstituée, on réduit et on maintient provisoirement les fragments osseux rassemblés au moyen de broches. Ces broches peuvent alors entraver l'introduction de la plaque dans l'espace réduit de la voie d'abord chirurgicale.PIN GUIDE FOR OSTEOSYNTHESIS OF FRACTURES
EPIPHYSO-METAPHYSAIRES BY PREFORMED SCREW PLATE
The device presented aims to facilitate osteosynthesis by so-called "anatomical" plates used for fractures of the bone ends by means of cannulated screws guided by pins. Before placing a plate against the reconstituted bone end, the collected bone fragments are reduced and temporarily maintained by means of pins. These pins can then hinder the introduction of the plate into the reduced space of the surgical approach.

L'invention vise à faciliter le scénario opératoire en utilisant ces broches comme guide de vis canulées qui fixent la partie épiphysaire de la fracture. The invention aims to facilitate the operating scenario by using these pins as a guide for cannulated screws which fix the epiphyseal part of the fracture.

Le dispositif de base (fig. 1) est un viseur des broches qui vont ensuite guider les vis canulées. The basic device (fig. 1) is a viewfinder for the pins which will then guide the cannulated screws.

II est composé principalement d'une plaque (A) préformée ayant exactement la forme de la partie épiphysaire de la plaque qui prendra ensuite sa place. La plaque (A) dispose d'orifices (1) dont le diamétre admet le passage des broches guides (B). It is mainly composed of a preformed plate (A) having exactly the shape of the epiphyseal part of the plate which will then take its place. The plate (A) has orifices (1) whose diameter allows the passage of the guide pins (B).

Ces orifices sont séparés les uns des autres par un entre axe (2) égal à celui des orifices de la partie épiphysaire de la plaque définitive. La plaque (A) est manipulée par le chirurgien grâce à un porte pièces (C) amovible, vissé dans un logement spécial (3) placé à la face externe de l'une des extrémités de la plaque. Afin que la partie épiphysaire de la plaque soit parfaitement axée par rapport au grand axe de la diaphyse, la plaque (A) dispose d'un orifice spécial (4) de diamètre identique aux autres orifices (1). Cet orifice (4) est placé sur une patte spéciale (5) et admet une autre broche (B') qui permettra de câler la plaque (A) et l'orientera de façon adéquate par rapport au grand axe de la pièce osseuse. These orifices are separated from each other by an axis between (2) equal to that of the orifices of the epiphyseal part of the final plate. The plate (A) is manipulated by the surgeon using a removable workpiece carrier (C), screwed into a special housing (3) placed on the external face of one of the ends of the plate. So that the epiphyseal part of the plate is perfectly oriented relative to the major axis of the diaphysis, the plate (A) has a special orifice (4) of identical diameter to the other orifices (1). This orifice (4) is placed on a special tab (5) and admits another pin (B ') which will allow the plate (A) to be cabled and will orient it adequately with respect to the major axis of the bone piece.

La plaque (A) utilisée pour placer les broches provisoires (B) et (B') et dont la fonction est de guider les vis canulées épiphysaires, aura la forme adaptée à toutes les épiphyses osseuses sur les faces desquelles sont habituellement appliquées les plaques d'ostéosynthése préformées. II y aura donc un jeu de plaques guides pour chaque modèle de plaque définitive. The plate (A) used to place the provisional pins (B) and (B ') and whose function is to guide the cannulated epiphyseal screws, will have the shape suitable for all bone epiphyses on the faces of which the plates are usually applied. 'preformed osteosynthesis. There will therefore be a set of guide plates for each model of final plate.

Une fois le dispositif en place (fig. 2), le chirurgien enlèvera la plaque guide (A) et la remplacera par la plaque définitive (D). La plaque sera automatiquement orientée par rapport au grand axe de la diaphyse grâce à la broche (B'). Once the device is in place (fig. 2), the surgeon will remove the guide plate (A) and replace it with the final plate (D). The plate will be automatically oriented relative to the major axis of the diaphysis by means of the pin (B ').

Il restera au chirurgien (fig. 3) à préparer le passage des vis canulées (F) au moyen d'un foret lui-même canulé (E). Ce n'est que lorsque les vis épiphysaires (F) seront en place que les broches (B) et (B') seront enlevées. II restera alors au chirurgien à placer les vis non canulées habituellement placées dans les autres orifices de la plaque.  It will remain for the surgeon (fig. 3) to prepare the passage of the cannulated screws (F) by means of a cannulated drill (E). It is only when the epiphyseal screws (F) are in place that the pins (B) and (B ') will be removed. It will then remain for the surgeon to place the non-cannulated screws usually placed in the other orifices of the plate.
