Abstract

The retainer has a screw (a) with a central unthreaded section (1). The screw also has a distal section (2) with a thread for spongy bone, and a proximal section (3) with a thread having a constant height. The screw can have a central channel to allow passage of a broach guide (4). Another proximal section (5) receives a turn screw which is channelled.

Description

VIS DE RAPPEL PAR COMPRESSION POUR OSTEDtiYHESE PECIGUT: SCREW COMPRESSION FOR RECALL OSTEDtiYHESE PECIGUT:
La présente invention concerne un type de vis utilisé en chirurgie osseuse pour toute fracture-séparation. The invention relates to a type of screws used in bone surgery for any fracture-separation.

Le mode de fixation de ces fractures est habituellement assuré par des vis introduites du côté opposé du trait de fracture. The binding mode of these fractures is usually ensured by screws introduced from the opposite side of the fracture line. Ces vis sont caractérisées par un filetage distal tandis que leur corps en est dépourvu. These screws are characterized by a distal thread while their body does not. Le vissage du fragment séparé permet son rappel vers la pièce osseuse principale grâce à l'appui de la tête de vis contre la corticale opposée. Threading the separated fragment allows its return to the main bone part through the support of the screw head against the opposite cortex. Ce procédé n'assure cependant pas le dosage de la compression et ne tient pas compte des variations de dureté du tissu osseux spongieux sur lequel la partie proximale du dispositif s'appuie. This method does not provide the determination of compression and does not take into account variations in hardness of the spongy bone tissue on which the proximal portion of the device is based.

Le dispositif selon la présente invention permet de pallier à cet inconvénient auquel s'ajoute le fait que dans la plupart des cas il peut être placé en percutané sous simple contrôle radiologique avec l'amplificateur de brillance grâce à une instrumentation adéquate. The device according to the present invention overcomes this drawback which is added the fact that in most cases it can be placed percutaneously under simple control with the X-ray image intensifier through appropriate instrumentation.

Le disposif présente en première caractéristique une vis A (figure 1) composée de trois segments : un segment central cylindrique (1) dénué de filetage qui compose le corps intermédiaire de la vis. The present disposif first characteristic screw A (Figure 1) consists of three segments: a central cylindrical segment (1) devoid of thread which makes up the intermediate body of the screw. Un segment distal (2) disposant d'un filetage à hauteur croissante puis décroissante pour assurer l'ancrage de la vis dans le tissu osseux spongieux. A distal segment (2) having an increasing and then decreasing height thread for anchoring the screws in the cancellous bone tissue. Enfin, un troisième segment proximal (3), partie originale de la vis, dénué de tête mais site d'un filetage régulier de hauteur constante et de longueur variable. Finally, a third proximal segment (3), original part of the screw head but devoid of site of a regular thread of constant height and variable length.

La vis A est canulée si nécessaire afin de permettre son guidage par une broche (4). A screw is cannulated if necessary to enable guiding thereof by a pin (4).
Elle dispose enfin à son extrémité proximale d'un embout (5) réservé à la prise du tournevis. Finally, it has at its proximal end with a tip (5) reserved for taking the screwdriver.

Le dispositif présente en 2e caractéristique la pièce B (figure 2). The device has in the second characteristic part B (Figure 2). C'est la pièce de vissage proximale qui vise à remplacer la tête d'une vis conventionnelle. This is the proximal threaded part which is intended to replace the head of a conventional screw. La pièce B est un anneau et donc une pièce creuse qui dispose d'un canal central (6). Part B is a ring and therefore a hollow part which has a central channel (6). Sa surface extérieure est munie d'un filetage large et de hauteur croissante de son extrémité proximale à son extrémité distale (7). Its outer surface is provided with a large thread and of increasing height from its proximal end to its distal end (7). Son extrémité distale dispose d'un embout (8) qui sert à recevoir un tournevis adéquat. Its distal end has an end piece (8) which serves to receive a suitable screwdriver.

La surface intérieure (figure3) (9) de la pièce B est munie d'un filetage à filet constant ce qui permet à la pièce B d'être vissée sur la partie filetée (5) de la vis A. The inner surface (Figure 3) (9) of the part B is provided with a constant net thread which allows the part B can be screwed onto the threaded portion (5) of the screw A.

Cette vis spéciale A est introduite (figure 4) dans la pièce osseuse grâce à un tournevis C dont la caractéristique est d'être canulé pour permettre le guidage par la broche (4). This special screw A is introduced (Figure 4) in the bone part with a screwdriver C whose characteristic is to be cannulated to allow the guide by the spindle (4). Surtout cet instrument dispose d'une poignée amovible (10) ce qui permet à l'instrument de servir de guide au tournevis de la pièce B, une fois la vis A en place, et la poignée (10) enlevée. Especially this instrument has a removable handle (10) which enables the instrument to provide guidance to the driver of the part B, when the screw A in place, and the handle (10) removed.

La séquence suivante (figure 5) consiste en effet à glisser la pièce de vissage B sur le guide C grâce à un tournevis D disposant d'un canal central dont le diamètre lui permet d'être glissé sur la tige C. The following sequence (Figure 5) is indeed to slide the screw-in section B of the guide C by a screwdriver D having a central channel whose diameter allows it to be slipped on the rod C.

Ainsi l'opérateur peut il visser la pièce B sur le filetage (5) proximal de la pièce A (figure 6) et ainsi doser la compression dans le foyer de fracture. Thus the operator can he screw part B on the thread (5) proximal to the part A (Figure 6) and thus the amount of compression in the fracture.
