Brief: Looking for a straightforward way to understand the manufacturing of high-precision medical components? This video provides a detailed walkthrough of how 316L stainless steel tubing is transformed into precision CNC milled liposuction needles. You'll see the advanced multi-axis CNC milling process that creates complex tip geometries and aspiration ports, and learn about the critical steps—from material selection to final inspection—that ensure exceptional accuracy and a flawless surface finish for surgical performance.
Related Product Features:
  • Manufactured from biocompatible 316L stainless steel tubing, certified to ASTM A269 and ISO 13485 standards for medical use.
  • Utilizes advanced multi-axis CNC milling to create precise distal tip configurations like Mercedes, bullet, or spatula designs.
  • Features strategically placed, CNC-milled aspiration ports with controlled size, shape, and electropolished edges to minimize tissue trauma.
  • Includes machined proximal connection features such as threads for Luer-lock hubs, ensuring perfect concentricity with the aspiration lumen.
  • Undergoes intensive deburring and full-body electrophishing to achieve a mirror-like finish with Ra ≤ 0.2 µm, reducing friction and bacterial adhesion.
  • Designed for surgical liposuction, body contouring, and fat grafting applications, supporting tumescent, ultrasound-assisted, and laser-assisted procedures.
  • Subject to 100% dimensional inspection and comprehensive cleaning to meet ISO 11737-1 bioburden standards and sterilization compatibility.
  • Available in outer diameters from 1.5 mm to 6.0 mm and lengths from 150 mm to 400 mm, with tight tolerance control on critical features.
FAQs:
  • What material is used for the Precision CNC Milling Liposuction Needle, and is it biocompatible?
    The liposuction needle is made from medical-grade 316L stainless steel tubing, which is certified to ASTM A269 and complies with ISO 13485 for traceability. It is biocompatible per ISO 10993-1 standards, ensuring safety for surgical use.
  • How does the CNC milling process ensure precision in the liposuction needle's design?
    Advanced multi-axis CNC milling allows for simultaneous turning and milling operations, creating complex tip geometries and aspiration ports with high dimensional accuracy. Critical features are held to tolerances of ±0.05 mm, and the process includes intensive deburring and electrophishing for a smooth, atraumatic finish.
  • What applications are these liposuction needles suitable for?
    These needles are designed for surgical liposuction, body contouring, and fat grafting procedures, including tumescent, ultrasound-assisted, and laser-assisted liposuction. They are also used in veterinary cosmetic surgery for similar body contouring applications.
  • What quality controls are in place during manufacturing?
    Each cannula undergoes 100% dimensional inspection using video measurement systems or CMM, comprehensive cleaning to meet ISO 11737-1 bioburden standards, and is supplied with metrology reports. The manufacturing process is conducted under ISO 13485, with support for regulatory requirements like Design History Files for OEMs.
