Dental Metal Syringe 2.2ml

The Dental Syringe Aspirating 2.2ml is a premium, surgical-grade stainless steel instrument specifically engineered for the safe, precise, and controlled administration of local anesthetics during dental and oral surgical procedures. Designed specifically to accommodate standard 2.2 ml dental glass anesthetic cartridges, this syringe integrates an active harpoon aspirating system that allows clinicians to verify needle placement prior to anesthetic deposition, effectively preventing accidental intravascular injection.

Key Clinical Applications

• Regional Nerve Block Injections: Provides superior tactile control and steady pressure distribution during deep injections, such as Inferior Alveolar Nerve Blocks (IANB).

• Infiltration Anesthesia: Ideal for supraperiosteal infiltration techniques across anterior and posterior maxillary or mandibular sites.

• Intravascular Verification: Enables swift active aspiration to verify that the needle tip has not penetrated a blood vessel, preventing systemic toxicity and complications.

• Surgical & Oral Procedures: Essential for routine extractions, periodontal surgeries, endodontic treatments, and implant site preparations.

Key Design & Functional Features

1. Precision Harpoon Aspirating Mechanism

The central plunger rod features a sharp, micro-machined stainless steel harpoon that firmly engages the rubber stopper (bung) of the 2.2 ml cartridge upon insertion. By pulling back slightly on the thumb ring, negative pressure is generated inside the carpule. If a blood vessel has been punctured, blood instantly draws into the cartridge, alerting the clinician to reposition the needle before injecting.

2. Dedicated 2.2 ml Open Side-Loading Barrel

The barrel is custom-dimensioned to hold 2.2 ml anesthetic cartridges tightly, preventing play or micro-movements during injection. The wide lateral viewing windows give full, unobstructed visibility of the solution volume and aspiration chamber throughout the procedure.

3. Ergonomic Ring-Grip & Balance

Designed with a smooth, contoured thumb ring and broad dual finger grips for comfortable, balanced one-handed operation. This structural leverage allows precise control over injection speed and tissue resistance, minimizing hand strain during repeated procedures.

4. Universal Needle Threading

The thread connection at the tip is precision-machined to accept standard short and long dental needles seamlessly, ensuring a leak-proof seal even under higher manual injection pressure.

Cleaning, Maintenance & Sterilization Guidelines

• Decontamination: Immediately after use, dismantle the cartridge and rinse thoroughly under cold water to flush away blood, saliva, or anesthetic residues.

• Ultrasonic Bath: Clean in an enzymatic solution to remove organic debris from the internal spring, harpoon tip, and barrel threads.

• Autoclaving: Autoclave at standard cycle parameters (121°C for 20 minutes or 134°C for 3–5 minutes).

• Inspection & Care: Periodically check the harpoon tip for sharpness and ensure smooth piston movement along the inner barrel.
