Description
La presente invention concerne une vis d'osteosynthese.The present invention relates to an osteosynthesis screw.
11 est bien connu d'utiliser des vis a os pour realiser une osteosynthese, c'est-3-dire pour rapprocher et maintenir en contact deux It is well known to use bone screws to carry out an osteosynthesis, that is to say to bring together and keep in contact two
parties d'os fracturees.fractured bone parts.
Avec les materiels existants, il est necessaire d'utiliser une meche pour percer un trou adapte a la mise en place de la vis dans lesdites parties d'os, et un taraud pour amenager un taraudage avec lequel le filet With existing materials, it is necessary to use a drill bit to drill a hole adapted to the placement of the screw in said bone parts, and a tap to provide a thread with which the thread
de la vis pourra venir cooperer.of the screw can come to cooperate.
Ces operations de percage et de taraudage ont pour inconvenient d'etre longues et parfois difficiles 3 realiser, en particulier dans le cas du traitement de petite os tels que ceux du metacarpe ou du metatarse. La presente invention vise 3 remedier 3 cet inconvenient fondamental. 1S A cet effet, la vis qu'elle concerne: - est cannulee, c'est-3-dire comprend un alesage axial permettant son engagement a coulissement sur une broche de guidage, et - comprend des encoches distales et des usinages distaux amenages dans sa paroi, delimitant au moins deux faces radiales qui forment, avec ledit alesage, des aretes de coupe osseuse, et au moins deux surfaces de depouille externes consecutives 3 ces faces radiales dans le sens du vissage de la vis, ces faces radiales, aretes de coupe et surfaces These drilling and tapping operations have the drawback of being long and sometimes difficult to carry out, in particular in the case of the treatment of small bones such as those of the metacarpus or metatarsus. The present invention aims to remedy 3 this fundamental drawback. 1S For this purpose, the screw which it concerns: - is cannulated, that is to say 3 includes an axial bore allowing its sliding engagement on a guide pin, and - includes distal notches and distal machining brought into its wall, delimiting at least two radial faces which form, with said bore, bone cutting edges, and at least two consecutive external relief surfaces 3 these radial faces in the direction of screwing of the screw, these radial faces, edges of cut and surfaces
de depouille permettant 3 la vis d'etre autoperforante et autotaraudante. clearance allowing 3 the screw to be self-drilling and self-tapping.
L'osteosynthese de deux parties d'un os fracture peut ainsi etre realisee par simple mise en piace dans les parties d'os d'une broche de guidage puis engagement de la vis sur cette broche et vissage de cette vis The osteosynthesis of two parts of a fractured bone can thus be carried out by simple placing in the parts of the bone of a guide pin then engagement of the screw on this pin and screwing of this screw
au travers de la partie d'os proximale et dans la partie d'os distale. through the proximal bone portion and into the distal bone portion.
L'utilisation de meches et de tarauds est des lors eliminee. The use of bits and taps is therefore eliminated.
De preference, la vis comprend trots faces radiales telies que precitees, regulierement reparties sur sa circonference, et au moins trots surfaces de depouille consecutives 3 ces faces radiales dans le sens du Preferably, the screw comprises three radial faces as above, regularly distributed around its circumference, and at least three consecutive relief surfaces on these radial faces in the direction of
vissage de la vis.screwing the screw.
La vis peut avoir une tete non filetee. The screw may have a non-threaded head.
Wile peut egalement avoir une tete filetee, presentant notamment un filet de pas inferieur a celui du filet du corps de la vis. Une telle vis, cite "a compression", permet de serrer l'une contre l'autre les deux partie d'os a reunir lorsque la tete de la vis vient stinserer dans la Wile can also have a threaded head, presenting in particular a thread with a pitch smaller than that of the thread of the body of the screw. Such a screw, referred to as "compression", makes it possible to tighten one against the other the two parts of bone to be joined when the head of the screw comes to settle in the
partie d'os proximale, compte tenu de la difference de pas de filet precitee. proximal bone part, taking into account the difference in thread pitch mentioned above.
La vis selon ['invention peut egalement etre "autosecable", c'est-a-dire etre reliee a un mandrin cannule proximal par un pont seeable se rompant au dela de 1'exercice sur la vis un seuil de couple determine. Ce mandrin permet de faciliter la fabrication et ia manipulation de la vis lors de sa mise en place. 11 permet egalement et surtout de controler le couple exerce sur la vis afin d'eliminer tout risque d'exercice d'un couple pouvant conduire a la rupture de la vis avant la complete mise en place de celle-ci, ce qui est particulierement avantageux dans le cas de vis de falbles dimensions, notamment destinees au traitement de petite os The screw according to the invention can also be "autosecable", that is to say be connected to a cannulated mandrel proximal by a seeable bridge breaking beyond the exercise on the screw a determined torque threshold. This mandrel makes it easier to manufacture and manipulate the screw during its installation. It also and above all makes it possible to control the torque exerted on the screw in order to eliminate any risk of exercising a torque which could lead to the rupture of the screw before the complete installation thereof, which is particularly advantageous in the case of screws of small dimensions, in particular intended for the treatment of small bones
tels que les os du metacarpe ou du metatarse. such as the metacarpal or metatarsal bones.
Pour sa bonne comprehension, I'invention est a nouveau decrite ci-dessous en reference au dessin schematique annexe representant, a titre d'exemple non limitatif, une forme de realisation preferee de la vis qu'elle concerne. La figure 1 en est une vue en perspective; La figure 2 est une vue de son extremite distale, a echelle agrandie; la figure 3 en est une vue de cote; la figure 4 en est une vue en coupe longitudinale; la figure est une vue de son extremite distale, en bout; les figures 6 a 9 vent des vues de differentes etapes successives permettant la mise en place de cette vis dans deux parties d'os fracturees; la figure 10 est une vue de la vis selon une variante de realisation; la figure 11 est une vue de la vis selon une autre variante de realisation, et la figure 12 est une vue de la vis selon encore une autre For its good understanding, the invention is again described below with reference to the accompanying diagrammatic drawing representing, by way of nonlimiting example, a preferred embodiment of the screw which it concerns.

En pratique, ainsi que cela appara^'t sur les figures 6 a 9, une broche 11 autoforante est tout d'abord mise en place au travers de la partie osseuse proximale 15 et de la partie osseuse distale 16 (cf. figure 6) puts, apres mesure de la profondeur d'enfoncement de la broche 11 au moyen d'une jauge appropriee, un alesoir cannule 17 est engage sur la broche 11 pour amenager un alesage proximal de reception de la tete 3 de la vis (cf. figure 7). La vis 1 est ensuite engagee sur la broche 11 et est actionnee en rotation au moyen audit outil pour realiser simultanement un forage et un taraudage dans l'os, autour de la broche 11, et permettre la mise en place de la vis dans les parties d'os 15, 16 (cf. figure 8), jusqu'3 engager completement la tete 3 de la vis dans la partie osseuse proximale (cf. figure 9). Cet engagement realise de serrage de cette partie osseuse proximale 15 contre la partie osseuse distale 16 du fait de la In practice, as appears from FIGS. 6 to 9, a self-drilling spindle 11 is firstly placed through the proximal bone part 15 and the distal bone part 16 (cf. FIG. 6) puts, after measuring the driving depth of the spindle 11 by means of an appropriate gauge, a cannula reamer 17 is engaged on the spindle 11 to provide a proximal bore for receiving the head 3 of the screw (cf. figure 7). The screw 1 is then engaged on the spindle 11 and is actuated in rotation by means of said tool to simultaneously carry out drilling and tapping in the bone, around the spindle 11, and allow the screw to be put in place. of bones 15, 16 (cf. FIG. 8), up to fully engaging the head 3 of the screw in the proximal bone part (cf. FIG. 9). This engagement of tightening this proximal bone portion 15 against the distal bone portion 16 due to the
