30G SUS304 Dental Irrigation Needle Tube For Root Canal Therapy , Two Vents , Closed End

The SUS304 Stainless Steel Dental Endodontic Irrigation Needting Needle Tube is a precision needle tube specifically designed for root canal irrigation. Featuring a closed, non-cutting tip with two opposing side vents, this needle tube is engineered to deliver irrigating solutions into the root canal system. The closed-end design prevents apical extrusion of irritants, significantly reducing the risk of chemical injury to periapical tissues, while the dual side vents ensure optimal hydraulic flow and debris removal. In endodontic therapy, chemical irrigation is as critical as mechanical instrumentation. This needle tube serves as the conduit for irrigants. Unlike open-end needles that direct fluid axially toward the apex, this closed-end, side-vented design directs flow laterally. This creates a turbulent flow pattern that is more effective at agitating the irrigant, removing the smear layer, and cleaning anatomical complexities like lateral canals, while maintaining the safety of the apical constriction.

As one of the leading manufacturer and supplier of medical grade stainless steel needle tubes, YUHONG GROUP has abundant experience in producing different kinds of medical needle tubes, such as dental irrigation needle tube, hypodermic needle tube, insulin needle tube, mesotherapy needle tube, injection needle tube, veterinary needle tube, blood collection needle tube, and so on. We can also customize non-standard needle tubes according to clients' drawings or samples.

Key Features of SUS304 Irrigating Needle Tube:

• Closed End (Safety Tip): Eliminates the risk of "irrigant extrusion" beyond the apex.
• Two Side Vents: Provides 180-degree opposed fluid dispersion. This maximizes the irrigation zone while preventing direct jetting that could force debris into the periapex.
• Corrosion Resistance: SUS304 offers superior resistance to highly reactive endodontic irrigants.
• Flexibility: The thin wall thickness allows for moderate flexibility to navigate curved canals without kinking, yet retains sufficient stiffness for tactile control.

Main Using Areas:

• Root Canal Therapy (Endodontics): The primary application for cleaning and shaping procedures.
• Veterinary Dentistry: For root canal treatments in animals (where longer lengths are often required).

Different Needle Points of Irrigating Needle Tube:

Different Applications of Irrigating Needle Tube:

• Apical Irrigation: Using a 30G, 31mm closed-end needle inserted to 1mm short of the working length to safely deliver fluid to the apical third.
• Smear Layer Removal: Alternating irrigation using the side-vent design to ensure the chelating agent reaches lateral walls and instrumented grooves.
• Obturation (Backfill): When used with a specialized hub, larger gauge (25G) needles can dispense thermoplasticized gutta-percha or sealers into the canal space.
• Intracanal Medicament Placement: Delivery of other intracanal medicaments via syringe attachment.
