Patent

CA 2524408

An endodontic obturator includes a body and a disposable cartridge containing gutta percha that is couplable with the body. By containing the gutta percha in a disposable cartridge, a dentist or other medical technician does not have to clean the body or other components of the obturator, thus reducing the amount of time required to clean the obturator after use. The obturator also includes a heater operable to heat the gutta percha in the disposable cartridge and a thermal barrier operable to resist the flow of heat from the heater to the rest of the body, In addition, the obturator includes a mechanism operable to generate pressure in the disposable cartridge to dispense the gutta percha. With the thermal barrier, a portion of the obturator~s body that a dentist or other medical technician might hold while injecting gutta percha into a patient~s tooth may be kept relatively cool.

L'invention concerne un obturateur endodontique comportant un corps et une cartouche jetable contenant de la gutta-percha pouvant être couplée au corps. Comme la gutta-percha est contenue dans une cartouche jetable, il n'est plus nécessaire de nettoyer le corps ou les autres composants de l'obturateur, de manière à réduire le temps nécessaire au nettoyage de l'obturateur après utilisation. L'obturateur comporte également un élément de chauffage capable de chauffer la gutta-percha dans la cartouche jetable, et une barrière thermique empêchant la chaleur de l'élément de chauffage de se propager vers le reste du corps. Par ailleurs, l'obturateur comporte un mécanisme servant à créer une pression dans la cartouche jetable afin de distribuer la gutta-percha. Ladite barrière thermique permet de maintenir à une température relativement basse, la partie de l'obturateur que le dentiste ou tout autre personnel médical doit manipuler lors de l'injection de gutta-percha dans la dent d'un patient.
