Syringe dispenser

Abstract

A motor driven syringe dispenser which has a syringe mounting part, a slider, and a connection for an endodontic motor. The syringe dispenser connects to an endodontic motor which is used to drive a plunger of a syringe placed in the syringe mounting part thereby expressing irrigant into a root canal for root canal therapy.

Description

FIELD OF THE INVENTION[0001]The present application generally relates to a syringe dispenser, and, more particularly, to a motor driven syringe dispenser comprising a syringe mounting part, a slider, and a connection for an endodontic motor wherein the syringe dispenser drives a syringe connected to an irrigation needle to express irrigant into a root canal for root canal therapy.BACKGROUND OF THE INVENTION[0002]Endodontic treatment is important when pulp, which is the soft tissue inside a root canal, becomes inflamed or infected. The inflammation or infection can be caused by deep decay, repeated dental procedures on the tooth or a crack or chip in the tooth. Irrigation has a central role in endodontic treatment. During and after instrumentation, the irrigants facilitate removal of microorganisms, tissue remnants, and dentin chips from the root canal through a flushing mechanism.[0003]In endodontics, irrigation may take place by a clinician by placing an irrigant (e.g. NaOCl, EDTA,...

AI Technical Summary

Benefits of technology

The present invention provides a battery powered handheld syringe dispenser for expressing an irrigant from a syringe. The dispenser comprises a motor, a slider, and a push button slide. The slider is connected to guide rods that confine its movement to a predetermined path, and engages a threaded screw that is operated by the motor to create a corresponding movement of the plunger and express the irrigant. The advantage of using a syringe pump control is that it provides a constant and potentially higher flow rate of irrigant being delivered within the root canal, as compared to the conventional method of manually expressing the irrigant. It also allows for increased velocity and pressure of the irrigant being expressed from the irrigation needle, enhancing the cleaning of the root canal.

Problems solved by technology

Typically, the larger the syringe, the more difficult it is to express the irrigant at a relatively high flow rate.

However since motors are usually expensive components of syringe pumps, it may be helpful to use existing endodontic motors to control a syringe dispenser wherein a clinician may use, for example, a foot pedal or push button from the endodontic motor to start / stop the dispenser.
