Comprehensive Technical Overview
LIJ Med Tube specializes in transforming high-performance medical-grade metals into highly challenging precision components through cutting-edge manufacturing processes. These two core components showcase our top-tier capabilities in microtubing micro-machining and laser micro-processing:
- Precision Micro-Notched & Slotted Flexible Tubing : Utilizing high-precision laser cutting and ultra-precision grinding technologies, we achieve equidistant, multi-angle micro-notching (slotted tubing) on microtubes with ultra-fine diameters. This process endows the inherently rigid metal tube with exceptional radial flexibility and kink resistance while maintaining excellent axial pushability. It is an ideal choice for the distal shaft and core structural elements of high-end interventional catheters and endoscopes.
- Precision Half-Groove & Side-Opening Microtubes : Through multi-axis micro-subtractive machining, we achieve perfect half-groove transitions and specific geometric side-openings at the distal end of ultra-fine tubes. The edges are perfectly smooth and burr-free, and the inner wall features extremely high smoothness, ensuring zero obstruction during fluid delivery, micro-sensor embedding, or device passage.
Why Choose LIJ Med Tube?
Dual Technical Dimensions—Tube & Needle Expertise: We fully understand that “Tubes” and “Needles” represent entirely distinct technical challenges and manufacturing barriers. LIJ Med Tube possesses deep industry accumulation in both ultra-fine tube manufacturing and ultra-sharp needle-point precision grinding, offering a one-stop solution from tube forming to distal functionalization.
Extreme Miniaturization Processing Capabilities: Challenging the absolute limits of micro-manufacturing, we can stably process ultra-fine medical tubes and needles with an Outer Diameter (OD) as small as 0.06mm, while strictly controlling dimensional tolerances at the micron level.
Top-Tier Surface & Edge Control: By introducing industry-leading electrochemical polishing and high-energy microscopic deburring processes, we ensure that the edges of all micro-slots, cutouts, and side windows remain flawlessly smooth under microscopic inspection, eliminating any risk of vessel wall damage or clinical complications.
- Comprehensive Bio-Material Mastery: Our production predominantly utilizes premium Austenitic Stainless Steel series (304, 304L, 316, 316L) as our foundation. Furthermore, we advanced our technology to successfully handle highly specialized alloys—such as Nitinol (Nickel-Titanium), Cobalt-Chromium (Co-Cr), and Platinum-Iridium (Pt-Ir)—for critical clinical devices.
Target Applications & Clinical Fields
These high-precision custom components serve as the critical underlying hardware for a wide range of advanced Class III and innovative medical devices:
- Cardiovascular & Neurovascular Intervention: Delivery catheters, flexible distal shafts for microcatheters, stent delivery systems, and platinum-iridium radiopaque marker segments.
- Minimally Invasive Endoscopy & Robotic Surgery: Serpentine flexible joints and multi-DOF drive and control microtubes for robotic surgical instrument arms.
- Ophthalmic & Neurosurgery Minimally Invasive Operations: Ultra-fine drainage tubes, puncture needle sheaths, and drug-delivery needles with custom-shaped cutouts.
- Continuous Glucose Monitoring (CGM) & Insulin Delivery: Ultra-fine insertion needle/tube components for glucose sensors and precision microtubes for micro-infusion pumps.
