Q1: What is the core advantage of the hollow lumen design for this suture cannula needle?
A1: The hollow inner channel allows sutures to pass directly through the needle body, realizing one-step puncture and suture guiding, simplifying deep-site suturing operations and shortening surgical time effectively.
Q2: Why adopt the long slender tapered shaft structure?
A2: The slim tapered shaft can reach narrow and deep anatomical positions smoothly, lowers puncture resistance greatly, and avoids excessive tissue separation during minimally invasive surgeries.
Q3: Can I customize total length, shaft diameter and tip bevel angle?
A3: Yes, full OEM customization is supported. We can adjust overall length, tube wall thickness, outer diameter and tip grinding angle strictly according to your surgical application requirements and drawings.
Q4: Which stainless steel grades are optional for this hollow suture cannula needle?
A4: We supply SUS304 and SUS316L stainless steel options. SUS316L performs better in anti-corrosion, fitting long-term contact with body fluids and repeated disinfection cycles.
Q5: Will the inner lumen have burrs that scratch sutures during use?
A5: We perform professional inner-wall deburring and polishing treatment. The smooth hollow channel will not fray or scratch sutures during threading and delivery processes.
