The present invention relates to a specific cannula allowing to be fixed on a dedicated implant to remain pending the installation of other dedicated implants, each having its own specific cannula, to ensure the conduction of a liquid or pasty material to through each of them and said implants dedicated to a targeted injection, thereby promoting the amalgam before hardening of the liquid or pasty material provided by the various implants. According to the invention, this specific cannula is composed of: - an injection cannula 1 recessed throughout its length L of a lumen 12; the distal portion 13 is provided with a left-hand threading 131 for screwing into the left-hand threaded thread 221 of a dedicated implant 2; and the proximal portion 11 comprises a tapping 111 called to cooperate with the thread 32 of the adapter bit 3 and a flat portion 112 for receiving any key screwing / unscrewing. - An adapter fitting 3 hollowed out of a slot 33, consisting of a thread 32 called to cooperate with the tapping 111 of the injection cannula 1 and a connector 31 forming a means of cooperation with a injector tubing. a purger 4 formed of a rod 41 of length L rigorously equal to the same length L of the injection cannula and whose threading 411 is called to cooperate with the tapping 111 of said injection cannula 1, and of a handle 42. The specific cannula according to the invention is particularly intended for surgical procedures. La présente invention concerne une canule spécifique permettant d'être fixée sur un implant dédié pour rester en attente de la pose d'autres implants dédiés, chacun étant doté de sa propre canule spécifique, pour assurer la conduction d'un matériau liquide ou pâteux au travers de chacune d'entre-elles et desdits implants dédiés à une injection ciblée, favorisant ainsi l'amalgame avant durcissement du matériau liquide ou pâteux apporté par les différents implants. Selon l'invention, cette canule spécifique est composée : - d
