Abstract

The protector for sutures passing through a bone comprises a curved, oval titanium alloy plate (1). This has apertures (1a) through which the sutures pass, so that when they are tied off they are no longer in contact with the bone.

Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

Dispositif de protection des sutures sur une partie osseuse L'invention se rattache au secteur des techniques chirurgicales pour l'ancrage de fils de suture dans les substances osseuses.  Device for protecting sutures on a bone part The invention relates to the field of surgical techniques for anchoring suture threads in bone substances.

L'invention trouve une application particulièrement avantageuse pour la réinsertion trans-osseuse des tendons de la coiffe des rotateurs rompus.  The invention finds a particularly advantageous application for the transosseous reinsertion of the tendons of the ruptured rotator cuff.

Cette application ne doit cependant pas être considérée comme limitative : application aux sutures ligamentaires : chevilles, genoux, ligaments latéraux, tendons rotuliens,... This application should not however be considered as limiting: application to ligament sutures: ankles, knees, lateral ligaments, patellar tendons, ...

La réinsertion trans-osseuse de la coiffe des rotateurs nécessite de réaliser différents points de suture avec des fils qui, après passage dans des tunnels osseux et lors de leur serrage, sont susceptibles d'engendrer des contraintes importantes sur la partie d'os séparant les tunnels. Ces contraintes peuvent entraîner la rupture des fils de suture et/ou provoquer des lésions de la partie de l'os provoquant un échec de la suture. Les contraintes en tant que telles résultent du fait que le ou les fils de suture sont directement en contact avec la partie d'os considérée notamment au niveau de la mise en tension desdits fils.  The transosseous reinsertion of the rotator cuff requires making different stitches with threads which, after passing through bone tunnels and during their tightening, are likely to generate significant stresses on the part of bone separating the tunnels. These stresses can cause the sutures to break and / or cause damage to the part of the bone that causes the suture to fail. The constraints as such result from the fact that the suture or sutures are in direct contact with the part of bone considered in particular at the level of the tensioning of said sutures.

L'invention s'est fixée pour but de remédier à ces inconvénients, de manière simple, sûre, efficace et rationnelle.  The object of the invention is to remedy these drawbacks in a simple, safe, effective and rational manner.

Le problème que se propose de résoudre l'invention est de mieux répartir les contraintes lors du serrage des noeuds pour éviter la rupture des fils et les lyses osseuses.  The problem that the invention proposes to solve is to better distribute the stresses when tightening the knots to avoid breaking the wires and the bone lyses.

<Desc/Clms Page number 2> <Desc / Clms Page number 2>

Pour résoudre un tel problème, il a été conçu et mis au point un dispositif de protection des sutures sur une partie osseuse, remarquable en ce qu'il comprend au moins une plaque rigide apte à prendre appui sur la partie d'os, ladite plaque présentant de agencements pour le passage des fils de manière à ce qu'après mise en tension et serrage desdits fils, ces derniers ne soient plus en contact avec la partie osseuse mais avec la plaque qui répartit les contraintes.  To solve such a problem, it was designed and developed a device for protecting the sutures on a bone part, remarkable in that it comprises at least one rigid plate capable of bearing on the bone part, said plate having arrangements for the passage of the wires so that after tensioning and tightening said wires, the latter are no longer in contact with the bone part but with the plate which distributes the stresses.

Le problème posé de pouvoir positionner correctement le ou les fils de suture par rapport à la partie d'os considérée, est résolu en ce que les agencements de la plaque sont constitués par une pluralité de trous débouchants formés dans son épaisseur.  The problem posed of being able to correctly position the suture (s) with respect to the part of bone considered, is solved in that the arrangements of the plate are constituted by a plurality of through holes formed in its thickness.

Pour résoudre le problème posé d'assurer un parfait appui de la plaque par rapport à l'os, la plaque est profilée en section en étant cintrée longitudinalement et/ou transversalement.  To solve the problem posed of ensuring perfect support of the plate relative to the bone, the plate is profiled in section by being bent longitudinally and / or transversely.

Avantageusement, la plaque a une forme générale ovoïde.  Advantageously, the plate has a general ovoid shape.

Pour résoudre le problème posé de pouvoir faire de l'imagerie par résonance magnétique, la plaque est réalisée en alliage de titane.  To solve the problem of being able to do magnetic resonance imaging, the plate is made of titanium alloy.

L'invention est exposée ci-après plus en détail à l'aide des figures des dessins annexés dans lesquels : - la figure 1 est, à grande échelle, une vue en plan de la plaque d'appui selon l'invention ;  The invention is set out below in more detail with the aid of the figures of the appended drawings in which: - Figure 1 is, on a large scale, a plan view of the support plate according to the invention;

- Figure 4 is a schematic view showing an example of application in no way limiting the use of the plate.

Pour résoudre le problème posé de mieux répartir les contraintes lors de la mise en place et du serrage des fils de suture utilisés pour différentes applications chirurgicales, le dispositif met en oeuvre une plaque rigide d'appui (1) apte à coopérer avec la partie d'os soumise aux efforts de contraintes lors de la mise en tension et du serrage du ou des fils de suture (F) notamment après passage dans des tunnels osseux (figure 4). La plaque (1) présente une pluralité de trous débouchants (la) formés dans son épaisseur pour permettre le passage du ou des fils de suture et leur répartition si nécessaire. La plaque (1) est de forme générale ovoïde avec un profil en section cintré longitudinalement et/ou transversalement.  To resolve the problem posed of better distributing the stresses during the positioning and tightening of the sutures used for different surgical applications, the device implements a rigid support plate (1) capable of cooperating with the part d bone subjected to stressing forces during tensioning and tightening of the suture (s) (F) in particular after passage through bone tunnels (Figure 4). The plate (1) has a plurality of through holes (la) formed in its thickness to allow the passage of the suture or sutures and their distribution if necessary. The plate (1) is generally ovoid in shape with a profile in section curved longitudinally and / or transversely.

Cette plaque (1) est réalisée dans un alliage de titane afin de pouvoir faire de l'imagerie par résonance magnétique. Les dimensions de cette plaque sont réduites. A titre indicatif, sa longueur (L) est de 15 mm, sa largeur (1) de 8 mm et son épaisseur (e) de 0,8 mm. Bien évidemment, ces caractéristiques dimensionnelles ne doivent pas être considérées comme limitatives. De même, l'ensemble de la plaque est soumis à tout traitement thermique et de dureté approprié.  This plate (1) is made of a titanium alloy in order to be able to do magnetic resonance imaging. The dimensions of this plate are reduced. As an indication, its length (L) is 15 mm, its width (1) 8 mm and its thickness (e) 0.8 mm. Obviously, these dimensional characteristics should not be considered as limiting. Likewise, the entire plate is subjected to any appropriate heat and hardness treatment.
