Device for continuous irrigation with activation in endodontics application

A dental device for delivering fluid continuously while activated in an endodontic application comprising:

• a hollow needle, a handle and a removable modular fluid delivery connector;
• wherein the hollow needle includes a distal end portion, an intermediate portion, and a connector portion;
• the intermediate portion and a distal end portion together forms a working portion;
• the working portion terminates in a tip and is configured to act on a root canal;
• wherein the handle at one end is configured to be affixed to the connector portion of the hollow needle;
• wherein the handle at opposite end is capable of being attached to an endodontic handpiece or a sonic agitator for the activation,
• wherein the hollow needle includes a plurality of openings on the connector portion and at least one opening on the distal end to allow fluid to be delivered through hollow needle, and
• wherein a removable modular fluid delivery connector is coupled to the hollow needle, wherein the connector includes fluid delivery conduits for communicating the fluid to at least one opening of the plurality of opening of the hollow needle, wherein the modular fluid delivery connector comprises an inner housing, an outer housing;
• at least two sets of O rings and at least two ball bearing assemblies, wherein the at least two set of O rings include a smaller ID O ring set having a smaller inner diameter than a larger ID O ring set, wherein the smaller ID O ring set is configured to seal the needle to the inner housing of the modular fluid delivery connector, wherein the larger ID O ring set is configured to seal the inner housing modular fluid delivery connector and outer housing of the modular fluid delivery connector.
