Device for continuous irrigation with activation in endodontics application

Abstract

Disclosed herein is a dental device for delivering fluid continuously while activated in an endodontic application. The dental device includes a hollow needle having a tip end and a connector portion; and a handle. One end of the handle is configured to be affixed to the connector portion of the hollow needle. The opposite end of the handle is capable of being attached to an endodontic handpiece or a sonic agitator for the activation. The connector portion includes at least one tube connector that is an integral part of the connector portion of the hollow needle or a plurality of openings on the connector portion to accommodate the hollow needle to a connector. The connector is a modular fluid delivery connector which is removable from the needle such that it can be reused.

AI Technical Summary

Benefits of technology

The patent text describes a device that can be used in dental root canal treatment. The device delivers fluid while also being activated, which helps to better clean the root canal. It includes a hollow needle and a handle that can be attached to a dental handpiece or sonic agitator. The device is designed to be reused by easily attaching and detaching the needle from the handle. Overall, the device helps to improve the effectiveness and sanitation of dental root canal treatment.

Problems solved by technology

The issue with this design is that the relatively large amount of opening within the stent does not allow for any pressurization of the fluid when exiting the device.

The “stent-like” design lends to increased fragility and increased risk for the device becoming damaged during use.

There is no discussion of the needle having any type of activation though which limits the efficacy of the device and requires much higher pressures of the irrigant to adjust for the lack of activation of the irrigant within the canal.

This can again limit the efficacy of the irrigation unless the pressures are much higher which increases the risk of apical extrusion of the irrigant thus potentially introducing toxic chemicals into the blood stream.

When tips that operate at an ultrasonic frequency (>20 kHz) contact the canal wall, it causes the tip frequency to dampen as well as the tip contact creates ledging which means small notches can be created on the canal wall which further destroys the root canal when contacted by the ultrasonic tip.
