Abstract

The drill (100) has a step (116), a mandrel (114) at an upper end, a blade at an end (111) for boring, and a lateral blade (112) for cutting a bone that is received in an adjacent cavity (113). The cavity is deep and presents a semi-circular area, and the mandrel presents a bore (115) for allowing passage of a cooling liquid. The step presents diameter larger than the diameter of the drill.

Description

Foret d'alésage et de collecte d'os à irrigation interneBore drill and internally irrigated bone collection

La présente invention concerne de manière générale la chirurgie et plus particulièrement un foret d'alésage osseux utilisé en implantologie dentaire ou autre chirurgie osseuse, ayant la particularité de pouvoir prélever de l'os grâce à une surface latérale en forme de lame et une concavité profonde adjacente à la lame le long du foret, concavité qui fait office de réceptacle de l'os. Ce foret peut aussi aléser l'os grâce à une lame situé à l'extrémité du foret.  The present invention relates generally to surgery and more particularly to a bone boring drill used in dental implantology or other bone surgery, having the particularity of being able to take bone thanks to a blade-shaped lateral surface and a deep concavity. adjacent to the blade along the drill, concavity which acts as receptacle of the bone. This drill can also bore the bone with a blade located at the end of the drill.

Les forets de récupération d'os sont hélicoïdaux et l'os prélevé de cette manière est récupéré dans des rainures peu profondes. De plus, un foret hélicoïdal ne peut pas avoir l'irrigation interne. En effet, un foret d'alésage doit pouvoir laisser passer de l'eau à travers le foret par un perçage afin de refroidir cet os lorsque le cas clinique le dicte.  The bone recovery drills are helical and the bone removed in this way is recovered in shallow grooves. In addition, a twist drill can not have internal irrigation. Indeed, a bore drill must be able to let water through the drill through a bore to cool the bone when the clinical case dictates.

Pour remédier à cet inconvénient, la présente invention propose un nouveau foret présentant une concavité axiale le long du foret qui n'exclut pas le passage de l'eau. Ce foret présente une surface de coupe intéressante pour la récupération d'une quantité d'os importante.  To overcome this drawback, the present invention provides a new drill having an axial concavity along the drill that does not exclude the passage of water. This drill has an interesting cutting surface for the recovery of a significant amount of bone.

Avantageusement, selon l'invention, la surface de coupe latérale du foret est à droite vue de face pour un forage dans le sens des aiguilles d'une montre, et cette surface est soit parallèle à l'axe du foret lorsque le foret est cylindrique, soit présente des divergences ou convergences par rapport à l'axe du foret lorsque le foret est cylindro-conique, ou ovalaire. Bien entendu, la lame peut être à gauche si le sens de coupe du foret est dans le sens inverse des aiguilles d'une montre.  Advantageously, according to the invention, the lateral cutting surface of the drill is right front view for drilling in the direction of clockwise, and this surface is either parallel to the axis of the drill when the drill is cylindrical or presents divergences or convergences with respect to the axis of the drill when the drill is cylindro-conical, or oval. Of course, the blade can be left if the cutting direction of the drill is in the opposite direction of clockwise.

Selon un mode de réalisation préférentiel du foret conforme à l'invention, la concavité est logée tout le long du foret et est adjacente à la lame latérale qui produit l'effet de coupe. Cette concavité peut être de forme variée non limitative. En coupe, on peut retrouver des formes semicirculaires, ovalaires, des formes en v, ou encore des formes issues d'un rectangle, d'un carré ou d'un trapèze.  According to a preferred embodiment of the drill according to the invention, the concavity is housed all along the drill and is adjacent to the side blade that produces the cutting effect. This concavity can be of various non-limiting form. In section, we can find semicircular forms, oval shapes, v-shaped shapes, or shapes from a rectangle, a square or a trapezium.

r;4 2878146 2 Selon ce mode de réalisation, le foret(100) a une extrémité en v dont la partie droite vue de face présente une lame (111) qui a un effet de coupe lorsque le foret tourne dans le sens des aiguilles d'une montre. Lorsque le foret doit travailler dans le sens inverse des aiguilles d'une montre, les lames se trouvent à gauche vue de face. Selon ce mode de réalisation, le mandrin du foret est percé en son centre pour laisser passer l'eau stérile en vue d'irrigation et du refroidissement du site osseux. Dans ce cas, le foret agit comme un foret d'alésage à irrigation interne.  According to this embodiment, the drill bit (100) has a v-end whose straight face seen from the front has a blade (111) which has a cutting effect when the drill rotates in the direction of the needles. 'a watch. When the drill has to work counterclockwise, the blades are on the left seen from the front. According to this embodiment, the mandrel of the drill is drilled at its center to let the sterile water for irrigation and cooling of the bone site. In this case, the drill acts as an internally irrigated bore drill.

La description qui va suivre en regard des dessins annexés, donnés en titre 10 d'exemples non limitatifs, fera bien comprendre en quoi consiste l'invention et comment elle peut être réalisée.  The following description with reference to the accompanying drawings, given by way of nonlimiting examples, will make it clear what the invention consists of and how it can be achieved.

La figure 1 est une vue de face d'un mode de réalisation préférentiel du foret selon l'invention (100).  Figure 1 is a front view of a preferred embodiment of the drill according to the invention (100).

Le foret présente une lame à son extrémité (111) qui sert à aléser et une lame latérale (112), qui sert à couper l'os qui est recueilli dans la concavité adjacente (113). L'extrémité supérieure du foret appelée mandrin (114) présente un perçage (115) pour laisser passer un liquide refroidissant.  The drill has a blade at its end (111) for reaming and a side blade (112) for cutting bone that is collected in the adjacent concavity (113). The upper end of the drill called mandrel (114) has a bore (115) for passing a cooling liquid.

Nous allons décrire ci-après brièvement l'utilisation du foret (100) : Dans une première étape, un premier alésage est réalisé dans l'os avec un 20 foret de petit diamètre.  The use of the drill (100) will be briefly described below: In a first step, a first bore is made in the bone with a small diameter drill.

Dans une deuxième étape, le foret (100) est utilisé dans le même axe que le premier foret. Lorsque le foret (100) est utilisé sans irrigation, la collecte d'os est importante. Lorsque ce foret est utilisé avec irrigation, on obtient uniquement l'action d'alésage.  In a second step, the drill (100) is used in the same axis as the first drill. When the drill (100) is used without irrigation, bone collection is important. When this drill is used with irrigation, only the boring action is obtained.

Le foret peut être fait à partir de n'importe quel métal, alliage de métal, recouvert ou pas, passivé ou pas, compatible avec la chirurgie osseuse.  The drill can be made from any metal, metal alloy, coated or not, passivated or not, compatible with bone surgery.

La concavité présente une étendue sur plus d'un demi-cercle (voir figure 2).  The concavity has an extent over more than one semicircle (see Figure 2).
