Abstract
A system for providing endodontic material includes an application device and a docking station for the application device. The application device includes a cartridge having a chamber structure containing endodontic material, with the chamber structure capable of being heated by magnetic induction. The application device also includes a handle assembly configured to hold the cartridge. The docking station includes a slot configured to contain the application device with a part of the application device positioned in the slot. The docking station is provided with an induction heating coil positioned adjacent to the slot, with the induction heating slot being configured to heat the cartridge of the application device.
Claims13
A system for providing endodontic material, the system comprising:
- (i) an application device comprising:
- (A) a cartridge including (a) a chamber structure containing endodontic material and (b) an outer sleeve having a flared part at one end of the outer sleeve;
- the outer sleeve configured to surround at least part of the chamber structure;
- and
- (B) a handle assembly configured to hold the cartridge;
- wherein the chamber structure is spaced from the outer sleeve by spacer pegs that extend between an outer surface of the chamber structure and an inner surface of the outer sleeve such that an air gap is formed between the outer surface of the chamber structure and the outer sleeve;
- wherein the chamber structure is formed from a ferromagnetic metal alloy material such that chamber structure is capable of being heated by magnetic induction, and
- (ii) a docking station including (a) a slot configured to contain the application device with a part of the application device being positioned in the slot, (b) at least one optical sensor facing the outer sleeve of the cartridge in order to detect a temperature of the cartridge of the application device, the docking station being provided with at least one induction heating coil positioned adjacent to the slot.
