Abstract

Viewing device for drilling the bone pieces of the knee during reconstruction of the transverse anterior ligament. The device comprises an angle (A) and an independent part (B). The first part comprises a rectangular member (1) with the second member (2) fixed perpendicular to it at one end. The second member carries a socket (3) that supports a further socket (C), hollowed for housing a drill bit (D). Part (B) is a straight shaft with a pointed hook (8) for hooking the bony cortical. Angle (A) and moving part (B) are used to correctly align the drilling bit, once alignment is complete they are removed prior to drilling.

DISPOSITIF DE VISEE POUR FORER LES CANAUX OSSEUX EN VUE DE REALISE LA RECONSTRUCTION DU LIGAMENT CROISE
ANTERIEUR (LCA) DU GENOU La reconstruction des ligaments du genou nécessite une parfaite précision dans la restitution des sites d'implantation anatomiques des 2 extrémités du nouveau ligament. La reconstruction la plus habituelle est celle du LCA situé au milieu et à la partie antérieure de l'articulation du genou.
SIGHTING DEVICE FOR DRILLING BONE CANALS WITH A VIEW TO REALIZING THE CROSS LIGAMENT
ANTERIOR (ACL) OF THE KNEE The reconstruction of the knee ligaments requires perfect precision in restoring the anatomical implantation sites of the 2 ends of the new ligament. The most common reconstruction is that of the ACL located in the middle and anterior part of the knee joint.

Pour accéder en particulier à la partie postérieure de la face interne du condyle externe, là où s'implante normalement le ligament, l'opérateur doit pouvoir manoeuvrer sans être sous la contrainte d'un instrument encombrant et qui imposerait une direction non souhaitée au forage. Le présent dispositif (fig. 1) est un cadre de visée composé de 2 pièces indépendantes l'une de l'autre et que l'on solidarise secondairement pour permettre une visée idéale, quelque soit le mode opératoire choisi, ouverture de l'articulation ou surtout sous arthroscopie.To access in particular the posterior part of the internal face of the external condyle, where the ligament is normally implanted, the operator must be able to maneuver without being under the constraint of a bulky instrument and which would impose an unwanted direction on drilling . The present device (fig. 1) is an aiming frame made up of 2 independent parts one from the other and which one secures secondarily to allow an ideal aiming, whatever the chosen operating mode, opening of the joint or especially under arthroscopy.

La pièce A est une pièce métallique angulaire composée de 2 branches à 900 l'une par rapport à l'autre : une barre (1) quadrangulaire à la coupe et tige (2) solidarisée à une des extrémités de la barre (1). L'autre extrémité de la tige (2) est munie d'une douille (3) qui reçoit la pièce C dont la fonction est de guider une broche D pour forer la pièce osseuse. L'autre extrémité de la barre (1) de la pièce A est échancrée d'une longue fenteThe part A is an angular metal part composed of 2 branches at 900 relative to one another: a bar (1) quadrangular in the cut and rod (2) secured to one of the ends of the bar (1). The other end of the rod (2) is provided with a socket (3) which receives the part C, the function of which is to guide a pin D to drill the bone part. The other end of the bar (1) of part A is notched with a long slit

verticale (4) ouverte à l'extrémité de la barre (1). Il y a une autre fente mais horizontale (5) et fermée, à l'extrémité de la pièce (1) située sur sa face verticale. Cette fente (5) vise à admettre un écrou (6) pour fixer la pièce B. La pièce B est un crochet indépendant de la pièce A mais à laquelle il va être solidarisé une fois la visée faite. Ce crochet B dispose d'une tige (7) à l'extrémité de laquelle se situe une pointe (8) qui sert à perforer la corticale osseuse au point idéal d'implantation du nouveau ligament. vertical (4) open at the end of the bar (1). There is another slot, but horizontal (5) and closed, at the end of the part (1) located on its vertical face. This slot (5) aims to admit a nut (6) for fixing the part B. The part B is a hook independent of the part A but to which it will be secured once the aiming has been made. This hook B has a rod (7) at the end of which is a point (8) which is used to perforate the bone cortex at the ideal point of implantation of the new ligament.

L'autre extrémité de la pièce B est un manche aplati (9) pour être glissé dans la fente (4) de la barre de la pièce A. Le manche (9) de la pièce B est muni sur toute sa longueur d'une série trous (10), échelonnés de 5 en 5 mm, ces trous (10) visent à recevoir l'écrou (6), une fois choisi l'emplacement adéquat du crochet B dans la fente (4) de la pièce A.The other end of part B is a flattened handle (9) to be slid into the slot (4) of the bar of part A. The handle (9) of part B is provided over its entire length with a series of holes (10), staggered from 5 to 5 mm, these holes (10) aim to receive the nut (6), once the appropriate location of the hook B has been chosen in the slot (4) of part A.

Ainsi la manoeuvre opératoire de mise en place du cadre de visée se déroule en 2 temps, soit en vue directe par arthrotomie ou sous vision arthroscopique, soit indirectement par contrôle radiographique per opératoire avec fluoroscopie : 'Le chirurgien introduit par une boutonnière cutanée le crochet B dans le milieu de l'articulation du genou et cherche à placer sa pointe (8) au site d'implantation anatomique normal.Thus, the operative maneuver for setting up the aiming frame takes place in 2 stages, either in direct view by arthrotomy or under arthroscopic vision, or indirectly by radiographic control per operative with fluoroscopy: 'The surgeon introduces by hook the skin button H in the middle of the knee joint and seeks to place its tip (8) at the normal anatomical implantation site.

'La fente (4) de la pièce A est introduite sur le manche (9) de la pièce B puis la pièce A est solidarisée à la pièce B par l'écrou (6) à angle et longueur voulus, mais sans serrage définitif afin de basculer la pièce A, et donc orienter sa douille (3), munie de sa pièce C, exactement dans l'axe de la pointe du crochet B. Une fois les 2 pièces en place, l'écrou (6) est serré, ce qui fixe l'appareil à la pièce osseuse à forer. Il reste alors à introduire la broche D, puis à démonter le cadre de visée (A + B). La broche D guidera ensuite successivement les forets de perçage du canal osseux. Il ne restera qu'à passer le néo ligament qui sortira en place de l'implantation anatomique normale.

'' The slot (4) of part A is introduced on the handle (9) of part B then part A is secured to part B by the nut (6) at the desired angle and length, but without final tightening so tilt the part A, and therefore orient its bushing (3), fitted with its part C, exactly in the axis of the point of the hook B. Once the 2 parts are in place, the nut (6) is tightened, which fixes the device to the bone part to be drilled. It then remains to introduce the pin D, then to dismantle the sighting frame (A + B). Pin D will then successively guide the drilling drills of the bone channel. It will only remain to pass the neoligament which will come out of the normal anatomical implantation.
