Abstract

An anchor screw and associated sliding-sleeve driver tool are provided, each having a longitudinal axial passage dimensioned to receive a guide shaft. The screw is formed of a titanium alloy material with suitable non-magnetic properties to allow later IRM examination of the patient. The thread of the screw is formed with a slightly rounded edge configuration, and an end portion of the screw defines a locating projection. The sliding sleeve of the driver tool is located and dimensioned to protect the ligament portion of the prosthetic tendon against damage during the driving operation. ADVANTAGE - Improved fastening accuracy and reduced damage to natural and prosthetic tissues.

Description

ta présente invention concerne un nécessaire de chirurgie orthopédique destine & la mies en place de vis d'ancrage utilisée en particulier dans la ligamentoplastie du genou.your present invention relates to an orthopedic surgery kit intended for the crumbs in place of anchor screws used in particular in knee ligamentoplasty.

Cette application n1 excluant pas d' d'autres domaines.This application does not exclude other areas.

Il est connu que dans certains cas de rupture des ligaments du genou, en particulier du ligament croisé antérieur, il peut être procédé au remplacement de celui-ci par # un tendon rotulien/tibial provenant soit d'une banque (allogreffe) soit prélevé sur le genou sain du patient (greffe autologue). It is known that in certain cases of rupture of the knee ligaments, in particular of the anterior cruciate ligament, it can be replaced by # a patellar / tibial tendon coming either from a bank (allograft) or taken from the patient's healthy knee (autologous transplant).

Le greffon qui a des extrémités osseuses est introduit dans un canal tibial et un canal fémoral qui lui fait suite. ta partie tendineuse remplira son rôle de tendon dans l'espace intercondilien. Pour ancrer les deux extrémités osseuses du tendon rotulien dans les tunnels fémoral et tibial on introduit dans chaque tunnel une vis qui solidarisera l'os tendineux à l'os du tunnel.The graft which has bone ends is introduced into a tibial canal and a femoral canal which follows it. your tendon part will fulfill its role of tendon in the intercondilar space. To anchor the two bony ends of the patellar tendon in the femoral and tibial tunnels, a screw is introduced into each tunnel which will secure the tendon bone to the bone of the tunnel.

L'intervention succinctement décrite ci-dessus donne des résultats favorables dans la majorité des cas,
Toutefois des complications indésirables surviennent parfois.The procedure succinctly described above gives favorable results in the majority of cases,
However unwanted complications sometimes arise.

Ces complications sont dues aux cisaillements occasionnées lors de la mise en place des vis d'ancrage4
Par ailleurs, les vis actuellement en usage sont réalisées dans des alliages plus ou moins magnétiques. Ceci gène 11 examen IRM que l'on pourrait être amena à effectuer par la suite sur le patient.These complications are due to shearing caused during the installation of the anchor screws4
Furthermore, the screws currently in use are made of more or less magnetic alloys. This gene 11 MRI examination which one could be brought to carry out subsequently on the patient.

te necessaire, objet de la présente invention est destiné à éviter de tels inconvénients.you need, object of the present invention is intended to avoid such drawbacks.

Il se compose donc Preièrement de vis d'ancrage réalisées en alliage de titane, métal dont les propriétés magnétiques sont comparables a celles du bois. Le dessin de ces vis est notablement modifié par rapport aux réalisations existantes, de manière à en améliorer les caractéristiques4 Deuxibmement d'un tournevis & coiffe coulissante, instrument sur, destiné à la prise et à la mise en place des vis décrites ci-dessus ou a leur retrait,et qui offre l'avantage de controler le vissage tout en protegeant le tendon des filets de la vis
Le vis d'ancrage , réalisée en alliage du titane, TA6V-ELI
Par exemple, comporte & son extrémité une partie conique d'introduction (9). Cette partie sonique est destinée a faciliter le passage de la vis dans le canal intre osseux1 ainsi qu'à favoriser l'amorcage correct du serrage de celui-ci. It therefore mainly consists of anchoring screws made of titanium alloy, a metal whose magnetic properties are comparable to those of wood. The design of these screws is significantly modified compared to existing embodiments, so as to improve their characteristics4 Secondly of a screwdriver & sliding cap, instrument on, intended for the grip and the installation of the screws described above or when removed, and which offers the advantage of controlling the screwing while protecting the tendon from the threads of the screw
The anchor screw, made of titanium alloy, TA6V-ELI
For example, has at its end a conical introduction part (9). This sonic part is intended to facilitate the passage of the screw in the internal bone channel1 as well as to promote the correct initiation of the tightening thereof.

Les cotes des filets sont déterminés de façon a offrir une large surface de contact entre les parties osseuses et la vis
Pour un meilleur ancrage et une bonne répartition des charges d'arrachement. De plus, pour éviter les pics de contrainte le bord des filets est émoussé par un léger arrondi (10). The dimensions of the threads are determined so as to provide a large contact surface between the bone parts and the screw
For a better anchoring and a good distribution of the tearing loads. In addition, to avoid stress peaks the edge of the threads is dulled by a slight rounding (10).

La vis est percée axialement (11) de manière & permettre le passage d'une broche guide, destinée a faciliter la mise en place.The screw is drilled axially (11) so as to allow the passage of a guide pin, intended to facilitate installation.

Pour éviter toute protubêrance gênante et pouvoir enfouir totalement la vis dans les tunnels osseux, celle-ci comporte, noyé en sa partie supérieure, un six pans creux. Ce six pans permet la mise en place de la vis à l'aide du tournevis d coiffe dont la description est données @ ci-aprs. To avoid any annoying protuberance and to be able to completely bury the screw in the bone tunnels, it comprises, embedded in its upper part, a hexagon socket. This hex allows the installation of the screw using the cap screwdriver whose description is given @ below.

Les vis peuvent avoir des longueurs et diamètres différents (par exemple 6x20, 6x25x 6x30 jusqu't 9x20, 9x30 etc..) pour couvrir une gamme complète.The screws can have different lengths and diameters (for example 6x20, 6x25x 6x30 up to 9x20, 9x30 etc.) to cover a full range.

te tournevis (1) est constitué d'un corps surmonté d'un manche (2) et d'une coiffe (5) comportant un ajour (8) assurant une visibilité de la vis.the screwdriver (1) consists of a body surmounted by a handle (2) and a cap (5) comprising an aperture (8) ensuring visibility of the screw.

La coiffe a pour but de protéger le tendon ou le ligament de tout traumatisme ou blessure que pourrait provoquer la vis au cours de la progression.The purpose of the cap is to protect the tendon or ligament from any trauma or injury that the screw may cause during progression.

La partie supérieure de la coiffe comporte un dispositif de coulissement (3) constitué, selon un premier mode de réalisation preférentiel, par une bille (15), un ressort (l6) et une vis (17).The upper part of the cap comprises a sliding device (3) constituted, according to a first preferred embodiment, by a ball (15), a spring (16) and a screw (17).

Ce dispositif permet de régler la tenue du coulissement (peu serré ou pas) de la coiffe sur la tige de l'appareil.This device makes it possible to adjust the sliding behavior (slightly tight or not) of the cap on the rod of the device.

Selon un deuxième mode de réalisation, ce dispositif de coulissement pourrait être constitue par un anneau élastique (cerclips par exemple) logé dans une gorge convenablement aménagée. According to a second embodiment, this sliding device could be constituted by an elastic ring (cerclips for example) housed in a suitably arranged groove.

Le tournevis et perce axialement sur toute sa longueur pour permettre le passage d'une broche guide. Un capuchon obturateur (14) est adapté & l'extrémité supérieure du manche pour empocher la sortie accidentelle de la broche guide. Ce capuchon peut être retiré aux fins de stérilisation et nettoyage du canal interne de l'appareil. The screwdriver and drills axially over its entire length to allow the passage of a guide pin. A sealing cap (14) is adapted to the upper end of the handle to pocket the accidental exit of the guide pin. This cap can be removed for sterilization and cleaning of the internal canal of the device.
