Abstract

La présente invention concerne un système d'instrument anti-rotation qui peut être utilisé dans toutes les professions de santé comprenant les spécialités médicale, dentaire, et autres. Le système comprend un dispositif d'instrument anti-rotation comprenant un manche principal, une première poignée amovible et un premier embout instrumental. La première poignée amovible est fixée à une première cavité de vis femelle située sur le manche principal. Une extrémité de l'embout instrumental traverse un canal situé dans la première poignée avec un verrouillage anti-rotation situé sur l'embout instrumental résidant de façon fixe à l'intérieur d'une encoche située sur une extrémité distale de la première poignée amovible ayant un filetage situé sur une extrémité de l'embout instrumental qui est ensuite vissé dans une première cavité de vis femelle du manche principal de sorte que la première poignée soit serrée en sandwich entre le premier embout instrumental et le corps principal.
