Abstract
La présente invention concerne un dispositif de coupe de la gencive, cette coupe étant complètement circulaire et parfaitement concentrique par rapport à un puits central laissé par un foret initial de petit diamètre. Ce dispositif est constitué d'une part par un bistouri circulaire (200) et d'autre part par un élément central (100) qui traverse le bistouri et qui est plus long que le bistouri. Cet élément central peut-être soit un foret, soit une tige cylindrique non coupante du même diamètre que le foret initial. Le bistouri peut-être démonté et séparé de l'élément central pour des besoins de nettoyage ou être non démontable. Ce dispositif peut-être actionné manuellement ou avec un instrument rotatif, tel que contre angle ou pièce à main. Le dispositif selon l'invention est destiné à la chirurgie des implants extra oraux et intra oraux, plus particulièrement à la chirurgie des implants dentaires.The present invention relates to a device for cutting the gingiva, this cut being completely circular and perfectly concentric with respect to a central well left by an initial drill of small diameter. This device is constituted firstly by a circular knife (200) and secondly by a central element (100) which passes through the knife and which is longer than the knife. This central element may be a drill or a cylindrical rod uncut the same diameter as the initial drill. The lancet may be disassembled and separated from the central element for cleaning purposes or may not be removable. This device can be operated manually or with a rotary instrument, such as against angle or handpiece. The device according to the invention is intended for the surgery of extraoral and intraoral implants, more particularly to the surgery of dental implants.
Description
Bistouri circulaire auto guidé par un élément central. Auto circular scalpel guided by a central element.
La présente invention concerne un dispositif de coupe de la gencive, cette coupe étant complètement circulaire et parfaitement concentrique par rapport à un puits 5 central laissé par un foret initial de petit diamètre. The present invention relates to a device for cutting the gingiva, this cut being completely circular and perfectly concentric with respect to a central well left by an initial drill of small diameter.
Les bistouris circulaires classiques ne contiennent pas d'éléments longs de guidage. Ils sont utilisés actuellement dans la chirurgie sans lambeau également appelée chirurgie micro invasive ou encore chirurgie sans ouverture. Conventional circular lancets do not contain long guide elements. They are currently used in flapless surgery also called micro-invasive surgery or surgery without opening.
L'utilisation de ces bistouris fait apparaître deux inconvénients : ^ Premièrement, le bistouri a tendance à glisser sur la gencive à cause de la force centrifuge due à la rotation du bistouri, ce qui entraîne la formation d'un orifice gingival irrégulière et imparfaitement circulaire, plutôt ovalaire. ^ Deuxièmement, le forage qui va être réalisé à travers cet orifice ne se situe pas complètement en son centre et l'agrandissement de ce puits intra osseux, par le passage des forets de plus gros diamètre, fait en sorte que le puits intra osseux final affleure le rebord gingival de l'orifice. There are two disadvantages to using these scalpels: Firstly, the scalpel has a tendency to slide on the gingiva because of the centrifugal force due to the rotation of the scalpel, resulting in the formation of an irregular and imperfectly circular gingival orifice rather oval. Secondly, the drilling that will be carried out through this orifice is not completely in its center and the enlargement of this intra-osseous well, by the passage of the larger diameter drills, makes the final intra-osseous well is flush with the gingival margin of the orifice.
A cause de ces deux inconvénients, la gencive est systématiquement entraînée dans le puits intra osseux lors de l'introduction de l'implant par vissage. Et, l'interposition de gencive entre l'implant et l'os peut entraîner la non- 25 ostéointégration de l'implant, sa mobilité et sa dépose pour éviter des infections. Because of these two disadvantages, the gingiva is systematically entrained in the intraosseous well during the introduction of the implant by screwing. And, the interposition of the gum between the implant and the bone may result in non-osseointegration of the implant, its mobility and removal to prevent infections.
Le dispositif selon l'invention permet de remédier à ces inconvénients : ^ Soit le dispositif est muni d'un foret qui dépasse bien la hauteur du bistouri circulaire. Dans ce cas, le foret traverse la gencive seule et 10 15 20 commence à pénétrer l'os. Ce n'est qu'une fois le foret bloqué dans l'os que le bistouri circulaire va ensuite agir. La découpe de la gencive est parfaitement circulaire car il n'y a pas de dérapage, et le puits intra osseux obtenu par le passage du foret est parfaitement au centre de l'orifice gingival. ^ Soit le dispositif est muni d'une tige cylindrique qui dépasse nettement la hauteur du bistouri circulaire. Dans ce cas, cette tige doit être du même diamètre que le foret qui a servi à faire le puits intra osseux en traversant la gencive. Lorsque le dispositif est à son tour utilisé, la tige centrale va être bloquée dans le puits intra osseux et contraint d'avancer dans la même direction que ce puits. Ce n'est qu'alors que le bistouri circulaire va faire sa découpe. Le résultat sera le même que dans le cas précédent, à savoir, un orifice gingival parfaitement circulaire, régulier et parfaitement concentrique par rapport au puits intra osseux. The device according to the invention overcomes these drawbacks: Either the device is provided with a drill which exceeds well the height of the circular knife. In this case, the drill passes through the gum alone and begins to penetrate the bone. It is only once the drill stuck in the bone that the circular knife will then act. The cutting of the gingiva is perfectly circular because there is no skidding, and the intraosseous well obtained by the passage of the drill is perfectly in the center of the gingival orifice. Either the device is provided with a cylindrical rod which clearly exceeds the height of the circular knife. In this case, this rod must be of the same diameter as the drill that was used to make the intra-bone well through the gum. When the device is in turn used, the central rod will be blocked in the intraosseous well and forced to advance in the same direction as this well. Only then the circular knife will cut. The result will be the same as in the previous case, namely, a gingival orifice perfectly circular, regular and perfectly concentric with respect to the intraosseous well.
On comprend aisément qu'il sera facile d'agrandir le puits intra osseux de façon concentrique et que le puits final sera bien centré et à distance de l'orifice gingival. It is easy to understand that it will be easy to enlarge the intraosseous well concentrically and that the final well will be well centered and away from the gingival orifice.
L'introduction de l'implant se fera à distance raisonnable de la gencive. Il n'y aura pas de gencive entraînée par l'implant. Par conséquent, l'ostéo-intégration de l'implant se fera dans de bonnes conditions. The introduction of the implant will be at a reasonable distance from the gum. There will be no gum entrained by the implant. Therefore, osseointegration of the implant will be done in good conditions.
25 Ce dispositif selon l'invention comporte : ^ D'une part, un bistouri circulaire soit démontable, soit non démontable. ^ D'autre part, un élément central qui dépasse nettement la hauteur du bistouri circulaire de façon à ce que cet élément central soit déjà 10 15 20 dans le puits infra osseux avant que le bistouri circulairecommence à découper la gencive. Cet élément central peut-être soit un foret soit une tige cylindrique non coupante. This device according to the invention comprises: On the one hand, a circular knife is removable or not removable. On the other hand, a central element which clearly exceeds the height of the circular knife so that this central element is already in the infra-bone well before the circular knife begins to cut the gingiva. This central element may be either a drill or a cylindrical rod uncut.
