Abstract

The anchor has two sections forming a male - female coupling which screws together. The female section (A) is of metal with a diameter the same as that of the screws used in surgery. The female section has longitudinal cut-outs (1) separating blades which are expanded by the male section. The male section is frusto-conical in form. The female section can have irregularities on its surface to encourage bone growth.

Description

DISPOSITIF D'ANCRAGE OSSEUX DES FILS DE FIXATION
UTILISES EN CHIRURGIE ORTHOPEDIQUE
Le dispositif vise à assurer un point d'appui fixe aux différents fils métalliques ou autres utilisés en chirurgie osseuse et ostéo-articulaire pour réinsérer capsule, ligaments, tendons et fragments osseux détachés. Dans ce dernier cas, le procédé est utilisé pour le traitement des fractures épiphysaires (rotule, olécrane, etc...).BONE ANCHORING DEVICE FOR FIXING WIRES
USED IN ORTHOPEDIC SURGERY
The device aims to provide a fixed point of support for the various metallic or other wires used in bone and osteo-articular surgery to reinsert capsule, ligaments, tendons and detached bone fragments. In the latter case, the method is used for the treatment of epiphyseal fractures (patella, olecranon, etc.).

Habituellement, les fils utilisés encerclent le fragment détaché et s'appuient sur la partie osseuse en place, après avoir ménagé un canal transfixiant par forage. Ce nouveau dispositif remplacerait le forage osseux transfixiant.Usually, the threads used encircle the detached fragment and rest on the bony part in place, after having formed a transfixing channel by drilling. This new device would replace transfixing bone drilling.

Le dispositif de base est composé de deux piéces séparées (figure 1) :
- La pièce (A) est une pièce métallique en forme de "dé à coudre", creuse, du diamètre habituel des vis utilisées en chirurgie osseuse. Elle présente 3 ou 4 fentes (1) dans le sens vertical sur une partie de la longueur de la pièce. Ces fentes séparent donc des lames (2) qui peuvent s'écarter de leur position initiale sans se casser dans les limites de leurs capacités élastiques. La surface extérieure de la pièce (A) est revêtue d'une surface irrégulière (3), de nature variable afin de disposer d'une meilleure adhérence dans le tissu osseux, dans lequel la pièce (A) est introduite.The basic device is made up of two separate parts (figure 1):
- The part (A) is a metal part in the shape of a "thimble", hollow, of the usual diameter of the screws used in bone surgery. It has 3 or 4 slots (1) in the vertical direction over part of the length of the part. These slots therefore separate the blades (2) which can deviate from their initial position without breaking within the limits of their elastic capacities. The external surface of the part (A) is coated with an irregular surface (3), of variable nature in order to have better adhesion in the bone tissue, into which the part (A) is introduced.

La surface intérieure de la pièce (A) est munie d'un filetage (4) pour admettre la pièce (B) par vissage. The interior surface of the part (A) is provided with a thread (4) to admit the part (B) by screwing.

Le fond de la pièce (A) est perforé d'un orifice (5) pouvant admettre le passage d'un fil dans le sens de sa longueur. The bottom of the part (A) is perforated with an orifice (5) which can accept the passage of a wire in the direction of its length.

- La pièce (B) est la partie male du dispositif. C'est une vis en métal ou tout autre matériau, dont la forme est troncônique. La partie du côté de la tête (6) est donc de plus grand diamètre que son extrémité (7). La base de la pièce (B) (6) est aussi de diamètre supérieur à l'orifice d'entrée de la pièce (A). Cette pièce est munie sur sa surface d'un filetage (8). Ainsi, en introduisant la pièce (B) par vissage dans la partie femelle (A), on crée un écartement des lames (2) de la pièce (A), ce qui assure un ancrage de celle-ci dans le tissu osseux. - The part (B) is the male part of the device. It is a metal screw or any other material, whose shape is frusto-conical. The part of the side of the head (6) is therefore of larger diameter than its end (7). The base of the part (B) (6) is also of greater diameter than the entry orifice of the part (A). This part is provided on its surface with a thread (8). Thus, by introducing the part (B) by screwing into the female part (A), a spacing of the blades (2) of the part (A) is created, which ensures that the latter is anchored in the bone tissue.

La pièce (B) est munie d'une tête (9), perforée d'un canal transversal (10) permettant le passage de fils de toute nature et de tout diamètre. La pièce (B) est également perforée dans le sens axial par un canal (11), ce qui, grâce à l'orifice (5) de la pièce (A), permet de passer un fil axial à travers les deux pièces (A) et (B) lorsqu'elles sont en place. The part (B) is provided with a head (9), perforated with a transverse channel (10) allowing the passage of wires of any kind and of any diameter. The part (B) is also perforated in the axial direction by a channel (11), which, thanks to the orifice (5) of the part (A), makes it possible to pass an axial wire through the two parts (A ) and (B) when in place.

La figure 2 montre le dispositif d'ensemble en place avec un fil (12) passé transversalement dans le canal (10) de la tête (9). Les figures 3, 4 et 5 montrent les modalités de mise en place du dispositif dans le tissu osseux: dans le premier temps (figure 3), c'est le forage de l'os par une mèche (13) de diamètre légèrement inférieur au diamètre extérieur de la pièce (A). Cette mèche est munie d'une butée (14) dont la distance de son extrémité est fonction de la longueur de la pièce (A) choisie par le chirurgien. La figure 4 montre l'introduction de la pièce (A) dans le canal osseux au moyen d'un porte-pièces vissé (15) dans la pièce (A). La figure 5 montre enfin le dernier temps de la mise en place du dispositif. C'est le vissage de la pièce (B) dans la pièce femelle (A), grâce à une clé (16). Par cette manoeuvre, le chirurgien crée l'écartement de la pièce (A) dans le tissu osseux, afin de provoquer l'ancrage osseux souhaité.  Figure 2 shows the overall device in place with a wire (12) passed transversely in the channel (10) of the head (9). Figures 3, 4 and 5 show the methods of placing the device in the bone tissue: in the first instance (Figure 3), it is the drilling of the bone by a drill bit (13) of diameter slightly less than the outside diameter of the part (A). This drill bit is provided with a stop (14) whose distance from its end depends on the length of the part (A) chosen by the surgeon. Figure 4 shows the introduction of the part (A) into the bone channel by means of a screwed workpiece carrier (15) in the part (A). Figure 5 finally shows the last time of the installation of the device. It is the screwing of the part (B) in the female part (A), thanks to a key (16). By this maneuver, the surgeon creates the spacing of the part (A) in the bone tissue, in order to cause the desired bone anchoring.
