Abstract

The screw (1) has a thread (1b) extending along its whole length. It has apertures in both ends, one in its tip to receive a guide rod (2), and one in its head for a drive tool (3). The aperture (1a2) in the head of the screw is inscribed within a circle and has two pairs of opposite flat surfaces. The flat surfaces in each pair lie at an obtuse angle to one another and at some 15 degrees to the vertical. The screw's thread has rounded outer and inner surfaces. At its conical tip, the bases of the thread grooves lie at an angle of 45 degrees to the axis of the screw. At the head end the groove, the bases form an angle of 20 degrees.

Description

VIS D'INTERFERENCE RESORBABLE, NOTAMMENT POUR LIGAMENTOPLASTIES. VIS INTERFERENCE ABSORBABLE, ESPECIALLY ligamentoplasties.

L'invention se rattache au secteur technique de l'orthopédie. The invention relates to the technical sector of orthopedics.

Il est parfaitement connu pour un homme du métier d'employer des vis d'interférence pour procéder à des ligamentoplasties, notamment pour la restauration des ligaments croisés postérieurs du genou. He is well known for a skilled person to employ interference screw to perform the ACL reconstruction, including the restoration of posterior cruciate ligaments of the knee. A cet égard, le ligament lésé est remplacé par un greffon généralement prélevé sur une partie du tendon rotulien avec à chaque extrémité des baguettes osseuses. In this regard, the injured ligament is replaced by a graft usually taken from a portion of the patellar tendon with bone at each end of rods. Le greffon est introduit dans deux tunnels osseux établis au niveau fémoral et au niveau tibial. The graft is inserted into bone tunnels established two femoral and tibial level. Le tunnel osseux tibial débouche très sensiblement au niveau des insertions du ligament. The tibial bone tunnel opens very substantially level with the insertions of the ligament. Les vis d'interférence sont engagées dans les tunnels osseux pour bloquer le greffon en combinaison avec chaque baguette osseuse. The interference screws are engaged in the bone tunnels to lock the graft in combination with each bone wand. La mise en place des vis d'interférence s'effectue généralement au moyen d'un tournevis en combinaison ou non avec une broche de guidage et de centrage. The establishment of the interference screw is generally carried out by means of a screwdriver or not in combination with a guide pin and centering.

Ces vis d'interférence peuvent présenter ou non une tête de manoeuvre. These interference screws may or may not have an operating head. Toutefois, la plupart d'entre elles ne présentent pas de tête de manoeuvre mais un alésage interne dont la section transversale est déterminée pour permettre l'engagement d'un organe rapporté apte à assurer I'entraînement de la vis concernée. However, most of them do not exhibit operating head but an inner bore whose cross section is determined to allow engagement of an insert member adapted to ensure I'entraînement the concerned screw.

On a proposé également des vis d'interférence qui sont réalisées en matière biorésorbable comme il ressort par exemple de l'enseignement du brevet EP-AO 615 732. Pour l'essentiel, ce brevet décrit une vis sans tête à filet rond et fabriquée à partir d'un stéréocopolymère de l'acide lactique de haute pureté chimique. They offered interference screws which are made of bioabsorbable material as appears for example from EP-AO 615 teaching the patent 732. Essentially, this patent describes a screw thread round head and made stéréocopolymère from a lactic acid of high chemical purity. Cette vis présente un alésage axial traversant dont une grande partie est constituée par un prisme creux pour être entraîné par un organe de manoeuvre de section complémentaire. This screw has an axial through bore of which a large part is constituted by a hollow prism to be driven by a complementary section of said actuator. L'extrémité avant de la vis est réalisée sous la forme d'un tronc de cone sur lequel s'étend le filet. The front end of the screw is designed as a truncated cone which extends net.

A partir de cet état de la technique, le problème que se propose de résoudre l'invention est d'améliorer la résistance mécanique de la vis compte tenu de la nature du matériau la constituant en vue de la rendre biorésorbable. From this state of the art the problem to be solved by the invention is to improve the mechanical strength of the screw given the nature of the material of the to make bioresorbable. En effet, dans le cas d'une vis résorbable, par définition, la résistance mécanique est faible, de l'ordre de 50 mégapascals, en opposition à une vis non résorbable, en titane par exemple, dont la résistance mécanique est de l'ordre de 800 mégapascals. Indeed, in the case of resorbable screws, by definition, the mechanical strength is low, of the order of 50 megapascals, as opposed to a non-absorbable screws, for example titanium, whose mechanical strength is the about 800 megapascals. Il est donc apparu important de conserver le maximum de matière au niveau notamment de la partie d'entraînement interne que présente la vis. It therefore seems important to keep the maximum material level including the internal drive part that presents the screw.

Autrement dit, le problème que se propose de résoudre l'invention est de réaliser une vis bio-résorbable, dont l'alésage d'entrainement présente une section transversale la plus éloignée d'un cercle, pour avoir un couple de serrage important. In other words, the problem to be solved by the invention is to provide a bioabsorbable screw, the drive bore has a distal cross-section of a circle, to have a significant torque. Il est apparu avantageux d'avoir une section méplate, tout en ayant pour objectif de pouvoir introduire une broche de centrage. It has proved advantageous to have a flattened section, while aiming to be able to introduce a centering pin.

Pour résoudre un tel problème, il a été conçu et mis au point une vis d'interférence résorbable, notamment pour ligamentoplasties présentant un alésage coaxial débouchant avec une portée d'extrémité de longueur réduite et de section transversale circulaire pour l'engagement d'une broche de centrage et une portée d'entraînement apte à recevoir un organe de manoeuvre, le filet s'étendant sur la totalité de la longueur de la vis, caractérisée en ce que la section transversale de la portée d'entraînement est très sensiblement méplate ; To solve such a problem, it has been designed and developed a screw absorbable interference, including ligamentoplasties having a coaxial bore with a short length end and scope of circular cross-section for engaging a centering pin and a drive surface adapted to receive an actuating member, the thread extending over the entire length of the screw, characterized in that the cross section of the drive surface is substantially flattened; notamment, cette portée est inscrite dans un cercle et présente deux portées méplates opposées et symétriques délimitant entre elles un angle obtu et en ce que chaque portée méplate fait avec la verticale un angle d'environ 15 . in particular, this range is within a circle and has two bearing surfaces opposite and symmetrical flatted delimiting between them an obtuse angle and in that each bearing is flattened with the vertical an angle of about 15.

Un autre problème que se propose de résoudre l'invention, compte tenu d'un emploi de vis sans tête, est de permettre au praticien de ressentir physiquement la fin du serrage en créant un effet de coincement tout en ayant pour objectif de faciliter l'engagement de la vis dans le tunnel préalablement établi. Another problem to be solved by the invention, given a job set screws, is to enable the practitioner to physically feel the end of tightening by creating a wedging effect while aiming to facilitate engagement of the screw in the pre-established tunnel.

Pour résoudre un tel problème, le fond de filet est établi successivement et en continuité à partir d'une portée d'extrémité tronconique d'engagement prolongée par une portée cylindrique ellemême prolongée par une autre portée d'extrémité tronconique de section transversale progressive, le diamètre externe du filet étant constant et cylindrique sur la longueur de la portée intermédiaire et la portée d'extrémité, opposée à la portée d'engagement. To solve such a problem, the thread root is established successively and in continuity from a tapered end bearing prolonged engagement with a cylindrical bearing surface itself extended by another frustoconical end bearing of progressive cross-section, the external diameter of the thread being constant and cylindrical along the length of the intervening land and the end bearing, opposite to the extent of engagement.

L'invention est également remarquable par les caractéristiques ci -après The invention is also remarkable for the following features -after
- les portées d'extrémités tronconiques sont de longueur réduite par rapport à la portée intermédiaire cylindrique; - the bearing surfaces are frustoconical ends of reduced length relative to the cylindrical intermediate range;
- la portée d'extrémité d'engagement délimite, en fond de filet, un angle d'environ 400 - the engaging end range defines, at the thread root, an angle of about 400
- la portée d'extrémité opposée à la portée d'engagement délimite, en fond de filet, un angle d'environ 200 - the end bearing opposite the engagement range defines, at the thread root, an angle of about 200
- la longueur de la portée intermédiaire cylindrique et de la portée d'extrémité tronconique opposée à la portée tronconique d'engagement, est très sensiblement égale à la longueur de la portée interne d'entraînement - the length of the cylindrical intermediate range and scope of tapered end opposite the frustoconical surface of engagement is substantially equal to the length of the inner drive range
- le fond de filet et son sommet sont largement arrondis. - the thread bottom and the top are widely rounded.

La vis désignée dans son ensemble par (1) comprend un alésage coaxial débouchant (la). The screw designated as a whole by (1) comprises a coaxial bore (la). Cette vis (1) présente extérieurement sur la totalité de sa longueur un filet (lb). This screw (1) has externally on its entire length a thread (lb). L'ensemble de la vis ne présente pas de tête et est réalisé en un matériau résorbable, par exemple la vis peut être réalisée, d'une manière connue, à partir d'un stéréocopolymère de l'acide lactique de pureté chimique. The set screw has no head and is made of a resorbable material, for example the screw can be carried out in a known manner, from a stéréocopolymère lactic acid chemical purity. On renvoie à l'enseignement du brevet EP 0 615 732 qui fournit à l'homme du métier des renseignements sur les caractéristiques de cette matière biorésorbable. It refers to the teaching of patent EP 0615732 which provides the skilled information on the characteristics of the bioabsorbable material.

L'alésage (la) présente une portée d'extrémité (lal) de longueur réduite et de section transversale circulaire. The bore (la) has an end surface (lal) of reduced length and circular cross section. De manière connue, cette portée interne (lal) est destinée à coopérer avec capacité de coulissement avec une broche de centrage (2). In known manner, this inner surface (lal) is intended to cooperate with the ability to slide with a centering pin (2). Cette portée (lal) est prolongée par une portée (la2) dont la section transversale est déterminée pour permettre l'engagement et l'accouplement d'une partie active (3a) d'un organe de manoeuvre (3). This range (lal) is extended by a range (a2) whose cross section is determined to allow engagement and coupling an active portion (3a) of an actuating member (3).

Selon les caractéristiques à la base de l'invention, cette portée d'entraînement (la2) a une section transversale inscrite dans un cercle et présente deux portées méplates (la3),(la4) opposées et symétriques. According to the characteristics at the base of the invention, the drive range (a2) has a cross section inscribed in a circle and has two bearing flatted (LA3), (la4) opposite and symmetrical. Les portées (la3) et (la4) délimitent entre elles, un angle obtu. Litters (la3) and (la4) delimit them an obtuse angle. Notamment, chaque portée méplate (la3) et (la4) délimite, avec la verticale XX', un angle (a) d'environ 15". il apparaît donc que cette section transversale est quasiment méplate et permet de conserver un maximum de matière au niveau de l'ensemble de l'alésage (la2). In particular, each flattened bearing surface (la3) and (la4) defines with the vertical XX ', an angle (a) of about 15 ". It appears that this cross section is almost flattened and preserves a maximum of material in level of the whole of the bore (Ia 2).

L'organe de manoeuvre (3), sous forme d'un tournevis, présente donc une partie active (3a) sous forme d'une tige dont l'extrémité délimite une portée (3al) de section complémentaire à la section transversale (la4), (la3) de la partie (la2) de l'alésage (la). The actuator (3) in the form of a screwdriver, thus presents an active portion (3a) in the form of a rod the end of which delimits a bearing surface (3al) of section complementary to the cross section (la4) (LA3) of the portion (a2) of the bore (la). L'ensemble de la tige est également percé coaxialement pour permettre l'engagement de la broche de centrage (2) susceptible de coopérer avec l'alésage (lal) de la vis. The whole rod is coaxially pierced to allow the engagement of the centering pin (2) capable of cooperating with the bore (lal) of the screw. Le montage de la vis d'interférence (1) en combinaison avec la broche de centrage (2) et au moyen du tournevis (3), n'est pas décrit en détail car parfaitement connu pour un homme du métier. The fitting of the interference screw (1) in combination with the centering pin (2) and using the screwdriver (3) is not described in detail as well known to one skilled in the art. A noter toutefois que la partie active (3a) du tournevis (3) est de section transversale très réduite pour passer au travers du tunnel tibial dans lequel a été préalablement placé le greffon. Note however that the active portion (3a) of the screwdriver (3) is of very small cross-section to pass through the tibial tunnel into which has been previously placed the graft. A noter également que le tunnel recevant le greffon peut, préalablement à la mise en place de la vis d'interférence, être soumis à l'action d'un conformateur (4) qui fait office de taraud. Also note that the tunnel receiving the graft may, prior to the establishment of the interference screw, be subjected to the action of a shaping device (4) which acts as a tap.

Avantageusement, ce conformateur (4) peut être du type de celui illustré figure 6. La tête (4a) est rapportée par rapport au corps (4b). Advantageously, this shaper (4) can be of the type shown in Figure 6. The head (4a) is attached to the body (4b). Par exemple, la tête (4a) présente une portée polygonale coopérant avec une empreinte complémentaire formée en bout de la tige (4b). For example, the head (4a) has a polygonal bearing surface cooperating with a complementary indentation formed in the end of the rod (4b). Compte-tenu de ces dispositions, il est particulièrement intéressant de procéder sous arthroscopie, en conformant toute la partie fémorale, après être passé au travers du tunnel tibial. Given these provisions, it is particularly interesting to conduct arthroscopic, conforming all the femoral part, after passing through the tibial tunnel. Le genou étant en position de flexion, la tige (4b) est engagée au travers du tunnel tibial et, après débordement, l'opérateur accouple la tête (4a) pour exécuter la partie fémorale. With the knee in flexion, the rod (4b) is engaged through the tibial tunnel and, after overflowing, the operator couples the head (4a) for performing the femur part. Il en résulte un parfait alignement pour la mise en place de la vis (1). The result is a perfect alignment for the establishment of the screw (1).

Bien évidemment, on n'exclut pas de réaliser un conformateur du type monobloc. Obviously, it is not excluded to make a shaper of the monobloc type.

Suivant une autre caractéristique importante de l'invention, le fond (lbl) du filet (lb) est établi successivement et en continuité à partir de trois portées successives (a,b,c). According to another important feature of the invention, the bottom (lbl) of the thread (lb) is prepared successively and in continuity from three successive bearing surfaces (a, b, c).

La portée d'extrémité (a) est de forme générale tronconique et constitue la portée d'engagement. The end bearing (a) is generally frustoconical and forms the scope of engagement. Cette portée (a) délimite en fond du filet un angle (ss) d'environ 40". This range (a) delimits the thread base an angle (ss) of about 40 ".

La portée intermédiaire (b) est cylindrique sur la totalité de sa longueur et est prolongée, à l'opposé de son raccordement avec la portée (a), par la portée (c) de forme tronconique. The intervening land (b) is cylindrical over its entire length and is extended, opposite to its connection with the surface (a), for the range (c) of frustoconical shape. Cette portée (c) est de section transversale progressivement croissante et délimite en fond de filet un angle d'environ 20 . This range (c) is of progressively increasing cross-section and thread root delimits an approximately 20 angle. Les portées d'extrémité tronconiques (a) et (c) sont de longueur réduite par rapport à la portée intermédiaire cylindrique (b). Litters of frustoconical end (a) and (c) are of reduced length relative to the cylindrical intermediate range (b).

Les portées (b) et (c) ont une longueur (L) sensiblement égale à la longueur de la portée interne d'entraînement (la2). The lands (b) and (c) have a length (L) substantially equal to the length of the inner drive range (a2).

Le diamètre externe (D) du filet (lb) est constant et cylindrique sur la totalité de la longueur L de sorte qu'au niveau de la portée (c), le fond de filet (lbl) doit créer un effet de coincement en fin de serrage de la vis. The outer diameter (D) of the thread (lb) is constant and cylindrical over the entire length L so that the level of the bearing surface (c), the thread root (lbl) is to create a wedging effect at the end screw clamping.

De manière connue, le fond de filet (lbl) et son sommet (lb2) sont largement arrondis. As is known, the thread root (lbl) and the top (lb2) are well rounded.

Bien évidemment, sans sortir du cadre de l'invention, la vis (1) peut être exécutée selon différents diamètres et longueurs déterminés en fonction des cas pathologiques à traiter. Of course, without departing from the scope of the invention, the screw (1) can be performed according to different lengths and diameters determined according to the pathological conditions to be treated.

Les avantages ressortent bien de la description, en particulier on souligne et on rappelle The advantages are apparent from the description, in particular, emphasized and recalled
- l'augmentation de la résistance mécanique résultant de la section transversale spécifique au niveau de la portée interne d'entraînement de la vis qui évite un enlèvement trop important de matière - increasing the strength resulting from the specific cross-section at the inner bearing surface for driving the screw which avoids an excessive removal of material
- la possibilité de ressentir la fin du serrage sous l'effet de coïncement résultant du fond de filet établi à partir de la portée tronconique d'extrémité, le diamètre externe du filet demeurant constant. - the possibility of experiencing the end of clamping under the effect of jamming resulting from the thread root established from the tapered end bearing, the outer diameter of remaining constant net.
