Abstract

The anchor consists of two threaded components (A,B) which fit one inside the other, with the final turns of component (A) causing the expansion of vanes created by vertical slits in component (B). Component (A) is made from six segments - a hexagonal head (3) with a hole (2) through it to receive the surgical wire (C), a shoulder and neck and a smooth truncated conical section to expand the vanes, a threaded segment and a pointed tip. Component (B) is hollow and cylindrical, with a rough outer surface and two, three or four vertical slits covering the upper two-thirds of its length. It has an upper section which extends to below the level of the slits, and a lower threaded section to receive component (A).

Description

DISPOSITIF D'ANCRAGE PAR IMPACTION ANCHORAGE DEVICE BY IMPACTION
DANS L'OS SPONGIEUX DES FILS DE FIXATION The OS SPONGE IN FIXING SON
UTILISES EN CHIRURGIE USED ​​IN SURGERY
On peut introduire par impaction toute pièce métallique dans le tissu osseux spongieux ou épiphysaire parce que sa dureté est beaucoup plus faible que celle de l'os compact. Can be introduced by impaction any metal part in the spongy bone or epiphyseal because its hardness is much lower than that of compact bone.

Une pièce métallique de petite taille et disposant d'une pointe peut être ainsi pénétrée dans la pièce osseuse par simple impaction. A metal part of small size and having a tip can thereby be penetrated into bone piece by simple impaction. Le présent dispositif possède cette caractéristique tout en permettant un ancrage définitif et la possibilité d'y passer ensuite un fil à usage chirurgical. This device has this feature while allowing a final anchor and the opportunity to then pass a surgical thread.

Le dispositif de base est composé de deux pièces vissées partiellement l'une dans l'autre avant impaction dans l'os (figure 1). The basic device consists of two parts partially screwed into one another before impaction into bone (Figure 1).

Lorsque le dispositif a été impacté, un vissage complémentaire de la pièce mâle (A) dans ia pièce femelle (B) permet l'ancrage osseux grâce à un mécanisme d'écartement des branches (1) ménagées dans la partie proximale de la pièce femelle (figure 2). When the device has been impacted, an additional screwing of the male part (A) in ia female part (B) allows the anchoring bone through one of the branches spacing mechanism (1) formed in the proximal portion of the female part (Figure 2).

L'ensemble du dispositif est alors en place et un fil (C) peut être placé dans un canal (2) ménagé dans la tete (3) de la vis (A) The entire device is then in place and a wire (C) may be placed in a channel (2) formed in the head (3) of the screw (A)
La pièce (A) (figure 3) est une vis miniaturisée disposant de haut en bas de 6 segments: The part (A) (Figure 3) is a screw having miniaturized from top to bottom of 6 segments:
- La tête de vis (3) possède un canal (2) dans lequel est passé le fil d'appui utilisé par le chirurgien. - the screw head (3) has a channel (2) in which is passed the support wire used by the surgeon.

- Un épaulement (4) sert de butée d'appui sur la surface osseuse afin que la pièce ne s'enfonce pas dans le tissu osseux après le vissage terminal. - a shoulder (4) serves as an abutment on the bone surface so that the piece does not penetrates into the bone tissue after the terminal screw. Cette partie doit donc être d'un diamètre supérieur à tous les segments sous jacents de la vis. This part should be of a diameter greater than all segments underlying the screw.

- Un col (5) dont la longueur détermine la profondeur de pénétration finale de la pièce (A) dans la pièce (B) et qui doit donc etre toujours supérieure au segment sous jacent (6). - a neck (5) the length of which determines the final penetration depth of the part (A) in the room (B) and therefore must be always greater than the underlying segment (6).

- Le segment (6) est un segment court, de forme tronconique, à base supérieure. - The segment (6) is a short segment, of frustoconical shape, at upper base.

Sa surface est lisse. Its surface is smooth. C'est cette partie, qui en pénétrant dans la partie femelle (B), assure l'écartement de ses branches (1) et donc, L'ancrage final de la pièce dans le tissu osseux spongieux. This part, which by penetrating into the female part (B), ensures the spacing of the branches (1) and therefore, the final anchorage of the part in the cancellous bone tissue.

- Le segment sous-jacent (7) est la partie filetée. - The underlying segment (7) is the threaded part. C'est cette partie qui assure la descente de la pièce (A) dans la pièce (B). It is this part which ensures the descent of the part (A) in the room (B). Cette partie doit avoir une longueur égale à celle de la pièce (B). This part must have a length equal to that of the workpiece (B).

- Enfin l'extrémité de la pièce (A) présente une pointe (8) qui dépasse l'extrémité de la pièce (B) avant l'impaction du dispositif dans l'os. - Finally the end of the piece (A) has a tip (8) which extends beyond the end of the part (B) prior to impaction of the device into the bone.

La pièce (B) (figure 4) est la partie femelle du dispositif : c'est une pièce cylindrique, creuse, dont les deux tiers supérieurs disposent de 2, 3 ou 4 fentes verticales (9) séparant 2, 3 ou 4 branches à charnière inférieure. The part (B) (Figure 4) is the female part of the device: it is a cylindrical piece, hollow, of which the upper two thirds have 2, 3 or 4 vertical slots (9) between 2, 3 or 4 branches bottom hinge. La surface extérieure de la pièce est artificiellement rendue rugueuse (10) afin de résister à la torsion lors du vissage final de la pièce (A) dans la pièce (B). The outer surface of the part is artificially roughened (10) to resist twisting during the final screwing of the part (A) in the room (B).

La surface intérieure de la pièce (B) présente deux parties : plus des deux tiers supérieurs (11) sont lisses, sans aucun filetage ; The inner surface of the part (B) has two parts over two upper thirds (11) are smooth, with no thread; tandis que la partie la plus basse (12) est munie de quelques filets destinés à recevoir la partie filetée (7) de la pièce (A). while the lower portion (12) is provided with a few threads for receiving the threaded portion (7) of the piece (A).

L'ensemble du dispositif avant usage chirurgical (figure 5) est manipulé par un instrument (D) dont l'extrémité vient s'encastrer sur le col (5) entre l'épaulement (4) et la base de la partie tronconique (6). The entire device before surgical use (Figure 5) is manipulated by a tool (D) whose end is embedded in the neck (5) between the shoulder (4) and the base of the frustoconical portion (6 ). Cet instrument permet un serrage du dispositif grâce à une molette intérieure. This instrument allows a clamping device through an inner wheel.

Grâce à cet instrument et un tournevis, le déroulement de l'opération est le suivant (figure 6): With this tool and screwdriver, the progress of the operation is as follows (Figure 6):
- 1er temps : impaction jusqu'à l'extrémité de l'instrument (D), - first time: impaction to the tip of the instrument (D),
- 2ème temps: ablation de l'instrument (D), - 2nd step: removal of the instrument (D),
- 3ème temps: la moitié supérieure du dispositif reste extérieure à la surface osseuse (segment 3, 4 et 5), - third time: the top half of the device remains outside the bone surface (segment 3, 4 and 5),
- 4ème temps : début de la procédure d'ancrage par vissage grâce à un tournevis emboité sur la tête de vis (3), - 4th step: Start the anchoring procedure by screwing with a screwdriver fits over the screw head (3),
- 5ème temps: le vissage est terminé, L'ancrage est obtenu et le chirurgien peut passer son fil dans le canal (2) de la tête de vis (3). - fifth time: the screwing is completed, the anchoring is obtained and the surgeon can pass the wire in the channel (2) of the screw head (3).
