Abstract

The present invention relates to a bone surgery drill (100) designed to ream and recover bone, comprising at least two blades arranged laterally with respect to the axis of the drill (figure 1: 111, 112) and at least two blades at the drill tip (figure 1: 113, 114). These blades, which can be plane, inwardly curved, or in two adjacent parts arranged at an angle to each other, either have individual cavities for recovery of bone (figures 1 and 2: 115, 116) or have a single cavity (figure 2: 117) formed by the union of the preceding cavities. This drill can also have a bore (figure 1: 123) extending along the mandrel (figure 1: 122) for bone irrigation, or an abutment (figure 1: 132) for stopping the advance of the drill at a certain level.

Description

Foret d'alésage et de récupération d'os à lames multiples. Bore drill and multi-blade bone recovery.

La présente invention concerne un foret utilisé en chirurgie osseuse, et plus particulièrement en implantologie dentaire et ce foret a la particularité de pouvoir prélever de l'os tout en réalisant un alésage de l'os et ceci grâce à des surfaces de coupe disposées le long du foret et à son extrémité, surfaces qui sont adjacentes soit à des cavités individuelles, soit à une cavité unique résultant de la réunion des cavités précédentes. Ces cavités servent à récupérer de l'os ainsi coupé lorsque le foret est en rotation.The present invention relates to a drill used in bone surgery, and more particularly in dental implantology and this drill has the particularity of being able to take bone while performing a bore of the bone and this thanks to cutting surfaces arranged along drill and at its end, surfaces that are adjacent either to individual cavities, or to a single cavity resulting from the reunion of previous cavities. These cavities are used to recover the bone thus cut when the drill is rotating.

Les forets de récupération d'os connus présentent des surfaces de coupe latérale disposées en hélice le long du foret. Par conséquent, la coupe est moins efficace et la quantité d'os récupérée n'est pas importante. Un autre foret connu pour la récupération d'os présente une seule lame latérale verticale. Ce dispositif perd son efficacité lorsque le foret est de gros diamètre.Known bone recovery drills have lateral cutting surfaces disposed helically along the drill. As a result, the cut is less efficient and the amount of bone recovered is not important. Another known drill for bone recovery has a single vertical side blade. This device loses its effectiveness when the drill is large diameter.

Pour remédier à cet inconvénient, la présente invention propose un nouveau foret présentant au moins deux lames latérales pour les diamètres courants et trois lames latérales ou plus pour les forets de gros diamètre. Ces forets présentent par ailleurs des lames à leurs extrémités, et aussi, soit des cavités individuelles de récupération d'os, soit une cavité commune résultant de la réunion des cavités précédentes. Ces cavités sont adjacentes aux lames.To overcome this drawback, the present invention proposes a new drill having at least two side blades for the common diameters and three or more side blades for large diameter drills. These drills also have blades at their ends, and also either individual cavities for bone recovery, or a common cavity resulting from the meeting of previous cavities. These cavities are adjacent to the blades.

Avantageusement, selon l'invention, les surfaces de coupe du foret, vu de face, sont d'abord une lame latérale par rapport à l'axe du foret, et ensuite une lame à l'extrémité du foret, et vu de l'arrière les surfaces de coupe du foret sont également une lame verticale le long du foret et une lame à la pointe, ces lames longeant soit deux cavités de récupération d'os séparées entre elles, ou une cavité unique unique faisant communiquer les deux cavités précédentes. Les lames du foret sont soit des surfaces planes présentant un angle entre elles, ou encore des surfaces pouvant présenter d'autres formes ayant une action de coupe lorsque le foret est en rotation.Advantageously, according to the invention, the cutting surfaces of the drill, seen from the front, are first a lateral blade with respect to the axis of the drill, and then a blade at the end of the drill, and seen from the behind the cutting surfaces of the drill are also a vertical blade along the drill and a blade at the tip, these blades along either two cavities for recovering bones separated from each other, or a single single cavity communicating the two previous cavities. The blades of the drill are either flat surfaces having an angle between them, or surfaces that may have other shapes having a cutting action when the drill is rotating.

D'autres caractéristiques non limitatives et avantageuses du foret selon l'invention sont les suivantes : - le foret présente trois lames (fîg 3) et soit trois cavités individuelles (fîg 3 : 127, 128, 129), soit une cavité unique (fig 3 : 130) résultant de la réunion des trois cavités.Other non-limiting and advantageous features of the drill according to the invention are the following: the drill has three blades (Fig. 3) and either three individual cavities (Fig. 3: 127, 128, 129) or a single cavity (Fig. 3: 130) resulting from the union of the three cavities.

- le foret présente plus de trois lames, et soit plusieurs cavités, soit une seule cavité. - le foret est de forme cylindro-conique (fig 4)- The drill has more than three blades, and either several cavities or a single cavity. - The drill is cylindro-conical (fig 4)

- le foret a une forme en marche d'escalier (fig 5).- The drill has a stair step shape (fig 5).

- le foret a une forme ovalaire (fîg 6)- the drill has an oval shape (Fig 6)
