Abstract

The implantable bone prosthesis (1) has a handling head rod (3) attached to the implant rod (2) by a point of weakness (4) which can break when the implant is in position to release the head. The point of weakness is situated at the base of a recess (7) in the implant section.

Description

La présente invention concerne les éléments prothétiques aptes à êtreThe present invention relates to prosthetic elements capable of being

implantés dans un os, notamment du corps humain, par exemple des vis, broches, clous,... qui sont utilisés pour fixer, sur des os, des éléments comme des plaques, des cotyles, des cages intersomatiques,..., ou pour réparer des fractures osseuses, etc. Ces éléments prothétiques sont généralement constitués par une première partie de tige qui peut comporter un ou plusieurs filetages o u analogues pour être apte à être implantée, par exemple par vissage, dans un os du corps humain, et par une seconde partie de tige liée à la première partie de tige, cette seconde partie de tige constituant essentiellement une tête de manipulation, par exemple une tête de vis ou analogue, qui permet d'agir sur la première partie de tige pour, par exemple, la visser dans l'os au moyen d'un  implanted in a bone, in particular of the human body, for example screws, pins, nails, ... which are used to fix, on bones, elements such as plates, acetabulum, interbody cages, ..., or to repair bone fractures, etc. These prosthetic elements are generally constituted by a first part of the rod which may comprise one or more threads or the like to be able to be implanted, for example by screwing, in a bone of the human body, and by a second part of the rod linked to the first part of the rod, this second part of the rod essentially constituting a handling head, for example a screw head or the like, which makes it possible to act on the first part of the rod to, for example, screw it into the bone by means of a

outil de vissage ou l'introduire par impactage ou analogue.  screwing tool or introduce it by impacting or the like.

Dans beaucoup de cas, la seconde partie de tige est liée à la première partie de tige par un point dit "de faiblesse" de façon à permettre, après que la première partie de tige ait été vissée et/ou introduite dans l'os, la séparation de ces deux première et seconde parties de tige, par cassure au niveau du point de  In many cases, the second part of the rod is linked to the first part of the rod by a point known as "of weakness" so as to allow, after the first part of the rod has been screwed and / or introduced into the bone, the separation of these two first and second parts of the rod, by breaking at the point of

faiblesse en exerçant sur elles un couple de forces, par exemple de torsion.  weakness by exerting on them a couple of forces, for example of torsion.

Cependant, la cassure ainsi obtenue n'est jamais nette et présente généralement des parties saillantes qui constituent des dangers de blessure pour les tissus humains qui entourent l'os dans lequel est implantée cette  However, the break thus obtained is never clear and generally has protruding parts which constitute a danger of injury to the human tissues which surround the bone in which this implant is implanted.

première partie de tige.first part of stem.

En effet, comme les os bougent toujours par rapport aux tissus comme les muscles, chairs, etc, qui les entourent, les parties saillantes au niveau de la cassure de la première tige ont tendance à blesser ces tissus par griffures, coupures, etc, et à créer des inflammations qui sont néfastes à la santé du patient. Des moyens particuliers ont été mis au point pour tenter d'éviter que les tissus ne soient blessés par ces parties saillantes. Ces moyens sont généralement des éléments rapportés constitués par des bouchons, capots ou analogues conçus pour recouvrir la partie saillante restant sur la première  Indeed, as the bones always move in relation to the tissues such as the muscles, flesh, etc., which surround them, the protruding parts at the level of the fracture of the first stem tend to injure these tissues by scratches, cuts, etc., and to create inflammations that are harmful to the health of the patient. Special means have been developed to try to prevent the tissues from being injured by these projecting parts. These means are generally added elements constituted by plugs, covers or the like designed to cover the projecting part remaining on the first

partie de tige après sa cassure.part of stem after breaking.

Cependant, tous ces moyens de protection connus ne donnent pas entière satisfaction. Car, comme conséquence des mouvements relatifs inévitables des os dans lesquels est implantée la première partie de tige, par rapport aux tissus qui l'entourent, le bouchon, capot ou analogue peut se détacher et ne plus jouer son rôle de protection en laissant à nouveau la  However, all of these known means of protection are not entirely satisfactory. Because, as a consequence of the inevitable relative movements of the bones in which the first part of the rod is implanted, relative to the tissues which surround it, the plug, hood or the like can detach and no longer play its protective role by leaving again the

portion saillante blessante en contact avec les tissus.  offensive protruding portion in contact with tissue.

La présente invention a pour but de réaliser un élément prothétique du type tige ou analogue, par exemple une vis, broche, etc, qui pallie les inconvénients mentionnés ci-avant des éléments prothétiques du même type, tout en ayant une structure très simple et très facile à réaliser. Plus précisément, la présente invention a pour objet un élément prothétique implantable dans un os du corps humain ou analogue, comprenant essentiellement une première partie de tige apte à être implantée dans l'os et une seconde partie de tige constituant une tête de manipulation, cette seconde -10 partie de tige étant reliée à la première partie de tige par un point de faiblesse de façon à pouvoir la séparer de la première partie de tige par cassure en exerçant un couple de forces respectivement sur les deux parties, l'élément prothétique étant caractérisé par le fait que ledit point de faiblesse est situé  The object of the present invention is to produce a prosthetic element of the rod or similar type, for example a screw, spindle, etc., which overcomes the disadvantages mentioned above of prosthetic elements of the same type, while having a very simple and very structure. easy to make. More specifically, the subject of the present invention is a prosthetic element implantable in a bone of the human body or the like, essentially comprising a first part of the rod capable of being implanted in the bone and a second part of the rod constituting a manipulation head, this second -10 part of rod being connected to the first part of rod by a point of weakness so as to be able to separate it from the first part of rod by breaking by exerting a couple of forces respectively on the two parts, the prosthetic element being characterized by the fact that said point of weakness is located

sensiblement au fond d'un puits réalisé dans la première partie de tige.  substantially at the bottom of a well made in the first part of the rod.

apparaîtront au cours de la description suivante donnée en regard du dessin  will appear during the following description given next to the drawing

annexé à titre illustratif, mais nullement limitatif, dans lequel: Les figures 1 et 2 représentent deux vues en coupe longitudinale d'un mode de réalisation d'un élément prothétique selon l'invention implantable dans un os du corps humain ou analogue, respectivement dans deux configurations, la figure 1 représentant la configuration dans laquelle se trouve l'élément prothétique avant son implantation et la figure 2 représentant la configuration dans laquelle l'élément prothétique se trouve  annexed by way of illustration, but in no way limiting, in which: FIGS. 1 and 2 represent two views in longitudinal section of an embodiment of a prosthetic element according to the invention implantable in a bone of the human body or the like, respectively in two configurations, Figure 1 representing the configuration in which the prosthetic element is located before its implantation and Figure 2 representing the configuration in which the prosthetic element is located

Il précise aussi que, si le mode de réalisation de l'objet selon l'invention tel qu'illustré comporte plusieurs éléments de fonction identique et que si,  It also specifies that, if the embodiment of the object according to the invention as illustrated comprises several elements of identical function and that if,

dans la description, il n'est pas spécifié que l'objet selon cette invention doit  in the description, it is not specified that the object according to this invention must

obligatoirement comporter un nombre particulier de ces éléments, l'objet de l'invention pourra être défini comme comportant "au moins un" de ces éléments. Les figures i et 2 représentent un élément prothétique 1 implantable  necessarily include a particular number of these elements, the object of the invention may be defined as comprising "at least one" of these elements. Figures i and 2 show an implantable prosthetic element 1

dans un os 100 du corps humain ou analogue.  in a bone 100 of the human body or the like.

Cet élément prothétique comprend essentiellement une première partie de tige 2 apte à être implantée dans l'os 100, par exemple par vissage, et une seconde partie de tige 3 constituant une tête de manipulation, par exemple une tête de vis, pour l'implantation de la première partie de tige. Cette seconde partie de tige 3 est reliée à la première partie de tige 2 par un point de faiblesse 4 agencé de façon à permettre, par cassure 5, la séparation des deux parties de tige 2, 3, cette cassure étant obtenue par exemple en exerçant un couple de  This prosthetic element essentially comprises a first part of rod 2 able to be implanted in bone 100, for example by screwing, and a second part of rod 3 constituting a handling head, for example a screw head, for implantation. of the first part of the stem. This second part of rod 3 is connected to the first part of rod 2 by a point of weakness 4 arranged so as to allow, by breaking 5, the separation of the two parts of rod 2, 3, this breaking being obtained for example by exerting a couple of

À10 forces respectivement sur les deux parties de tige.  At 10 forces respectively on the two parts of rod.

Selon une caractéristique importante de l'élément prothétique selon l'invention, ce point de faiblesse 4 est situé sensiblement au fond 6 d'un puits 7 réalisé dans la première partie de tige 2, en précisant que l'expression "situé sensiblement au fond du puits" signifie que le point de faiblesse est le plus éloigné possible du bord 9 du puits 7, sans être obligatoirement situé sur la  According to an important characteristic of the prosthetic element according to the invention, this point of weakness 4 is located substantially at the bottom 6 of a well 7 made in the first part of the rod 2, by specifying that the expression "located substantially at the bottom from the well "means that the point of weakness is as far as possible from the edge 9 of the well 7, without necessarily being located on the

paroi de fond du puits.bottom wall of the well.

Dans une réalisation préférentielle, les deux première 2 et seconde 3 parties de tige sont définies selon un même axe longitudinal 10 et l'axe 8 du puits 7 est sensiblement confondu avec cet axe longitudinal 10 commun aux  In a preferred embodiment, the two first 2 and second 3 parts of the rod are defined along the same longitudinal axis 10 and the axis 8 of the well 7 is substantially coincident with this longitudinal axis 10 common to

deux parties de tige.two parts of rod.

En outre, de façon avantageuse, la seconde partie de tige 3 est reliée à la première partie de tige 2 par une portion de tige de forme sensiblement tronconique 11. La petite base 12 de la portion de tige tronconique est solidaire du fond 6 du puits 7, la hauteur de cette portion de tige tronconique est supérieure à la profondeur du puits 7, figure 1, les sections transversales respectivement des deux première et seconde parties de tige sont sensiblement égales, et le puits 7 est sensiblement de forme cylindrique de révolution autour  In addition, advantageously, the second part of rod 3 is connected to the first part of rod 2 by a portion of rod of substantially frustoconical shape 11. The small base 12 of the portion of frustoconical rod is secured to the bottom 6 of the well 7, the height of this portion of frustoconical rod is greater than the depth of the well 7, FIG. 1, the cross sections respectively of the two first and second parts of the rod are substantially equal, and the well 7 is substantially of cylindrical shape of revolution around

de l'axe 8.of axis 8.

De plus, la section, dans un plan contenant l'axe 8 du puits 7, du bord annulaire 9 de ce puits présente une forme arrondie, c'est-à-dire une forme courbe sans arêtes anguleuses de façon à éviter tout risque de blessures des tissus qui entourent l'os 100 au niveau de l'endroit o a été implanté l'élément prothétique. L'élément prothétique selon l'invention trouve une application particulièrement avantageuse comme vis, clou, broche, etc, implantable dans un os 100 pour, par exemple, réduire une fracture, fixer une prothèse telle qu'un cotyle de prothèse de hanche, une plaque de maintien, etc.  In addition, the section, in a plane containing the axis 8 of the well 7, of the annular edge 9 of this well has a rounded shape, that is to say a curved shape without angular edges so as to avoid any risk of injuries to the tissues surrounding the bone 100 at the location where the prosthetic element was implanted. The prosthetic element according to the invention finds a particularly advantageous application as a screw, nail, pin, etc., implantable in a bone 100 for, for example, reducing a fracture, fixing a prosthesis such as a hip prosthesis acetabulum, a holding plate, etc.

A la description faite ci-dessus, il apparaît nettement que la structure de  From the description given above, it clearly appears that the structure of

l'élément prothétique selon l'invention ne présente pas les inconvénients des éléments prothétiques du même type de l'art antérieur. En effet, grâce à cette structure, la partie saillante blessante qui reste sur la première partie de tige après sa cassure S est automatiquement située au fond 6 du puits 7 et ne sera pas au contact des tissus entourant le bord 9 de ce puits. Il n'est donc pas nécessaire d'utiliser des éléments de protection rapportés comme des  the prosthetic element according to the invention does not have the drawbacks of prosthetic elements of the same type of the prior art. Indeed, thanks to this structure, the offensive projecting part which remains on the first part of the rod after its break S is automatically located at the bottom 6 of the well 7 and will not be in contact with the tissues surrounding the edge 9 of this well. It is therefore not necessary to use added protective elements such as

bouchons, capots ou analogues.stoppers, covers or the like.

Un autre avantage de l'élément prothétique selon l'invention est constitué par le fait qu'il ne présente aucune difficulté de réalisation, car il peut être très facilement obtenu au moyen d'un tour d'usinage à partir d'une  Another advantage of the prosthetic element according to the invention consists in the fact that it presents no difficulty in production, since it can be very easily obtained by means of a machining lathe from a

tige métallique en titane ou analogue de forme cylindrique ou similaire.  titanium or similar metal rod of cylindrical shape or the like.
