FAQ:

Q1: What does "Penpoint" specifically refer to in "Penpoint Side-Hole Needle"? What are its clinical advantages?

A:​ "Penpoint" refers to the needle tip being slender and sharply conical, similar to a fountain pen nib. This design makes the tip extremely sharp with minimal resistance during puncture, allowing precise entry into small or fragile target areas. Compared to traditional beveled needles, the penpoint design reduces the risk of accidental injury to blood vessels or nerves, making it particularly suitable for procedures requiring high precision in ophthalmology, plastic surgery, or interventional radiology.

Q2: How does the side-hole design differ from a single-hole needle in practical use?

A:​ A single-hole needle delivers fluid in a concentrated, high-impact jet, which can easily cause tissue damage or fluid extravasation. In contrast, a side-hole needle allows fluid to exit evenly through multiple small holes above the tip, creating a fan-shaped or diffused distribution. This results in gentler, more uniform perfusion, effectively covering the target area while reducing physical impact on surrounding healthy tissues, making it ideal for scenarios like tumor perfusion or cyst irrigation where wide-area coverage is required.

Q3: What practical assistance does the sandblasted tail provide during surgical operations?

A:​ The sandblasting process increases the friction on the needle tail surface. During surgery, doctors typically operate with sterile gloves, and smooth metal surfaces can easily slip. The sandblasted tail provides better grip, allowing the doctor to apply precise force when puncturing, aspirating, or stabilizing the needle. It also enhances the stability of the connection with the syringe, preventing accidental needle dislodgement due to excessive operational force or fluid pressure.

Q4: Is this needle suitable for repeated sterilization and reuse?

A:​ This product is made of medical-grade stainless steel with good corrosion resistance, supporting high-temperature, high-pressure sterilization (e.g., autoclaving) or low-temperature plasma sterilization. However, the specific number of reuses should comply with the standards of the hospital's Central Sterile Supply Department (CSSD) and the product instructions to ensure safety and performance.
