FAQ:

Question: Why choose a lancet-shaped tip instead of traditional bevel or triangular needles?

Answer:​ The lancet-shaped tip is designed to "cut rather than tear" during soft tissue puncture. Its symmetrical double-edge design cleanly slices through the skin or epidermal layer upon insertion, forming a smaller wound that closes quickly. Compared to traditional bevel needles, it better protects subcutaneous tissue structures and reduces the risk of medicine leakage into the subcutaneous space, making it especially suitable for dermal injections or superficial tissue treatments where aesthetics are important.

Question: What are the practical uses of the black scale rings on the needle body during clinical operations?

Answer:​ These scale rings serve three main purposes: 1) Depth control: They help doctors precisely control the insertion depth based on individual patient differences (e.g., children vs. adults), avoiding over-penetration or under-penetration; 2) Instrument identification: Different needle specifications can be configured with different scale spacings for quick recognition and retrieval in the operating room; 3) Operation guidance: During continuous micro-injections, the scales act as reference lines for each insertion, ensuring accurate dosing.

Question: What are the special advantages of the side-hole design in medicine delivery?

Answer:​ The side-hole design diverts the medicine outlet from the tip's apex to the side wall, allowing the liquid to spread in a fan or ring shape along the needle shaft upon injection, rather than forming a single high-pressure jet stream like a straight-hole needle. This dispersion method effectively reduces the instantaneous pressure on surrounding tissues, minimizes stimulation to nerve endings, and ensures a more uniform distribution of the medicine within the target area, thereby improving therapeutic outcomes.
