Customized Knurled Head X‑Ray Visible Medical Lancet Puncture Needle

Product Advantages:

Medical-grade stainless steel material, good biocompatibility and high corrosion resistance after repeated sterilization.
Lancet sharp cutting tip reduces tissue resistance and realizes smooth low-trauma puncture.
Knurled radiopaque tip can be clearly positioned under X-ray, making surgical location accurate and reliable.
Uniform knurling processing without burrs, the long shaft maintains high straightness for deep-site penetration.

FAQ:

Q1: What is the function of the knurled radiopaque tip?
A1: The knurled structure improves the radiopacity of the needle head, so the tip position can be clearly displayed under X-ray fluoroscopy, helping doctors accurately control the puncture depth and position during minimally invasive surgery.
Q2: Why choose the lancet cutting tip?
A2: The lancet sharp edge cuts tissue cleanly instead of tearing it, which greatly reduces tissue trauma, shortens recovery time and avoids unnecessary tissue damage during puncture.
Q3: Can we customize the length, outer diameter and knurling depth of the needle?
A3: Yes, we support full OEM customization. We can adjust the total length, tube outer diameter, wall thickness, knurling position and depth strictly according to your drawings.
Q4: What stainless steel material options do you have?
A4: We provide SUS304 and SUS316L stainless steel. SUS316L has better anti-corrosion performance and can withstand multiple high-temperature disinfection cycles without rusting.
Q5: Will the knurling leave sharp edges that scratch tissue?
A5: We use precision knurling followed by deburring and polishing. The knurled surface is smooth without sharp corners, so it will not scratch surrounding tissue during insertion and withdrawal.
