27G SUS304 Medical Endodontic Irrigating Needle Tube , Bendable Side Vented Blunt Tip

The SUS304 Medical Grade Stainless Steel Endodontic Irrigating Needle Tube is a precision-microfabricated cannula designed specifically for root canal therapy (endodontics). It is characterized by its small gauge (e.g.: 27G, 30G), construction from biocompatible SUS304 stainless steel, and a specialized side-vented blunt tip. This design allows for the safe and effective delivery of irrigating solutions into the root canal system while minimizing the risk of irrigant extrusion beyond the apex (apical perforation). This endodontic irrigating needle tube ia mainly used for gentle applications in root canal treatment and periodontal pockets. YUHONG GROUP has abundant manufacturing experience of dental endodontic irrigating needle tubes with good quality. Different needle tips can be customized according to clients' requirements.

• Primary Function: To flush out debris, dissolve organic tissue, and disinfect the complex intricacies of the root canal system.
• Safety Mechanism: The blunt tip prevents the needle from gouging or packing debris into the apical delta, while the side vent (a laser-cut hole on the side of the tube) redirects the fluid flow laterally rather than projecting it forcefully out the end.
• Material Rationale: SUS304 stainless steel provides the necessary rigidity to navigate a straight or moderately curved canal but remains bendable enough to be pre-curved by the clinician to match the canal anatomy.

Key Features:

• Bendable Ductility: Unlike harder alloys, SS304 allows the clinician to pre-curve the needle for better access to curved roots.
• Safety Blunt Tip: Prevents iatrogenic damage to the apical tissue and dentin wall.
• Side-Vent Design: Dramatically reduces the risk of "apical extrusion" of toxic irrigants into the periapical tissues, which can cause severe swelling.
• Corrosion Resistance: SUS304 withstands the corrosive effects of strong disinfectants.

Surface Finish of SUS304 Endodontic Irrigating Needle Tube:

The surface finish is critical for biocompatibility and to prevent tissue irritation or corrosion.

• Inner Surface: Must be smooth and free of burrs or debris to ensure laminar flow of the irrigant and prevent blockages.
• Outer Surface: Typically has a bright annealed finish. It is clean, oxide-free, and passivated.

Different Needle Points of Endodontic Irrigating Needles:

• Side-Vented (Lateral Vent): The most common and safest. The orifice is on the side of the needle. Fluid exits laterally, creating backflow along the canal walls. This is the type described in the product name.
• Open-End (Blunt but Not Vented): Fluid exits directly from the end. Generally not recommended for deep irrigation due to high apical pressure.
• Closed-End / Multi-Vented: The tip is closed (rounded), and multiple small holes are laser-drilled around the sides (like a shower head) for multidirectional, low-pressure irrigation.

Different Applications of SUS304 Medical Endodontic Irrigating Needle Tube:

• Root Canal Disinfection
• Smear Layer Removal
• Final Rinse For Disinfection.
• Apical Negative Pressure Irrigation
• Drying
