FAQ:

Question: Why is this 11G side-hole needle called a "Pen-Tip" needle? What is the difference between it and ordinary side-hole needles?

Answer:​ "Pen-Tip" is a figurative description of its front-end geometric shape. Ordinary side-hole needles usually just have simple holes drilled on the side, whereas our pen-tip needle undergoes special bevel cutting, resulting in a sharp, directional tip resembling a fountain pen nib.

The difference lies in: First, the pen-tip design makes it easier to penetrate tough tissues or fascia. Second, when fluid exits, the front bevel guides it to form a more concentrated fan-shaped spray, covering a larger area with a gentler water flow that is less damaging to tissues.

Question: Is the Luer Lock fitting at the tail fixed or detachable?

Answer:​ The image shows a fixed, integrated Luer Lock fitting. This design provides maximum structural strength and is less likely to detach or break under high-pressure irrigation or vigorous aspiration. However, if you have specific tubing connection needs, we can also provide a detachable version with threaded locking (Luer Slip or Luer Lock) according to your drawings.

Question: In which specific medical fields is this large-bore side-hole needle typically used?

Answer:​ Thanks to its 11G large flow capacity and low-trauma side-hole characteristics, it is mainly used in:

1. Orthopedics & Trauma Surgery:​ Large-volume rapid irrigation and drainage of hematomas or blood accumulation in joint cavities.

2. Plastic & Maxillofacial Surgery:​ Large-area soft tissue dissection, filler injection, and post-operative irrigation in facial areas.

3. Ophthalmic Surgery:​ Silicone oil or gas injection after vitrectomy, as well as anterior chamber irrigation.

4. Veterinary Medicine:​ Abdominal or thoracic fluid drainage in large animals.
