Sterilized catheter piercing needles are single-use, medical-grade needles designed specifically for body piercing procedures. And some key features and details about sterilized catheter piercing needles:

1. **Design:** Catheter piercing needles are designed with a hollow bore and a sharp beveled tip, allowing for precise and controlled insertion during piercing procedures. The length and gauge (diameter) of the needle can vary depending on the specific piercing technique and location.

2. **Sterilization:** Sterilization of catheter piercing needles is paramount to ensure the safety and hygiene of the piercing procedure. These needles undergo rigorous sterilization processes using methods such as autoclaving, ethylene oxide (EO) sterilization, or gamma radiation. Sterilization ensures that the needles are free from pathogens, bacteria, and other contaminants before use.

3. **Medical-Grade Material:** Catheter piercing needles are typically made from high-quality surgical steel or titanium, known for their durability, sharpness, and biocompatibility. These materials are safe for use in piercings and minimize the risk of allergic reactions or complications.

4. **Single-Use:** To maintain sterility and prevent cross-contamination, catheter piercing needles are often designed for single-use only. After each procedure, the needle is disposed of properly according to medical waste disposal guidelines.

5. **Gauge and Length Options:** Catheter piercing needles come in various gauges (diameters) and lengths to accommodate different piercing techniques and anatomical variations. Piercers select the appropriate needle size based on the specific piercing procedure and client's anatomy.

6. **Professional Use:** Catheter piercing needles are used by experienced and trained piercers who follow strict hygiene protocols and safety measures during piercing procedures. Proper technique, sterile equipment, and aftercare instructions are crucial for a successful and safe piercing experience.

Overall, sterilized catheter piercing needles are essential tools in certain piercing procedures, ensuring sterility, safety, and precision during the piercing process. They are part of a comprehensive approach to maintaining hygiene and minimizing risks associated with body piercings.
