Abstract

The invention relates to a device for making an incision in the gingiva, characterised in that it includes a circular scalpel (200) and a central element (100), whereby the scalpel has a cutting zone (201) and the central element has one end that extends substantially beyond the length of the scalpel so that it can be inserted into the intraosseous cavity before the scalpel begins cutting the gingiva, such that the gingival incision is perfectly circular and concentric in relation to the intraosseous cavity.

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 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.The use of these scalpels has two disadvantages: "First, the knife tends to slide on the gum 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.
• 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.• Secondly, the drilling that will be performed through this hole is not completely in its center and the expansion of this intra-osseous well, through the passage of 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-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 can lead to non-osseointegration of the implant, its mobility and its removal to avoid infections.
Le dispositif selon l'invention permet de remédier à ces inconvénients :The device according to the invention overcomes these disadvantages:
• 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 commence à pénétrer P 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.• Either the device is equipped with a drill which exceeds well the height of the circular knife. In this case, the drill passes through the gingiva alone and begins to penetrate the bone. Only once the forest is blocked in the bone that the circular scalpel 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 that 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. 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.
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.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.
Ce dispositif selon l'invention comporte :This device according to the invention comprises:
" D'une part, un bistouri circulaire soit démontable, soit non démontable."On the one hand, a circular knife is removable or not removable.
" D'autre part, un élément central qui dépasse nettement la hauteur du bistouri circulaire de façon à ce que cet élément central soit déjà dans le puits intra osseux avant ' que le bistouri circulaire commence à découper la gencive. Cet élément central peut-être soit un foret soit une tige cylindrique non coupante.On the other hand, a central element which clearly exceeds the height of the circular scalpel so that this central element is already in the intraosseous well before the circular scalpel begins to cut the gum. This central element may be either a drill or a cylindrical rod uncut.
Les dessins annexés illustrent l'invention : " La figure IA représente en coupe le dispositif selon l'invention lorsque le foret est présent. Le bistouri est démontable. " La figure IB représente en coupe le dispositif selon l'invention lorsque la tige cylindrique non coupante est présente. Le bistouri n'est pas démontable. " La figure 2A représente en vue d'avion la découpe de la genciveThe accompanying drawings illustrate the invention: "Figure 1A shows in section the device according to the invention when the drill is present The knife is removable."
