As core consumables in the medical field, the manufacturing accuracy of medical needles and tubes directly affects the safety of clinical operations and patient experience. Traditional processing methods (such as mechanical cutting and chemical corrosion) have problems such as low efficiency, burr residue, and material deformation. Laser cutting technology has become a disruptive solution for the manufacturing of medical needles and tubes due to its non-contact processing, high energy density, and intelligent control.

 

Taking BlueBird's medical needle tube laser cutting machine as an example, the system integrates a three-axis/four-axis precision motion platform with a nanosecond pulse laser, which can achieve high-precision cutting of stainless steel needles with a diameter of 0.18mm-3.4mm. The AI ​​visual positioning system captures the needle tube position in real time, and the galvanometer dynamically adjusts the laser path. The cutting edge roughness Ra≤0.8μm and the verticality deviation ≤0.05° fully meet the strict requirements of medical stainless steel needles for rigidity and toughness.

 

The medical needle laser cutting machine uses a 1064nm fiber laser. When cutting 304 stainless steel, by optimizing the laser power (80-120W) and auxiliary gas (high-pressure oxygen), a cutting speed of 15m/min can be achieved on a 0.1mm thin-walled tube, and the width of the heat-affected zone is controlled within 0.05mm.

For titanium alloy needles for orthopedic surgery, femtosecond laser cutting technology can achieve nano-level texture processing on the surface of titanium alloy and enhance the biocompatibility of the needle body and tissue.

 

The laser cutting machine monitors the change of material thickness in real time and automatically adjusts the focus position. When cutting a 0.3mm thin-walled needle tube, the dynamic adjustment accuracy of the focus depth reaches ±0.005mm, and the cutting speed is increased to 20m/min, which is 60% higher than the traditional fixed focus technology. In addition, laser cutting technology processes micro-groove structures (depth 20-30μm) at the tip of the needle tube, which can reduce the puncture force by 25% and the area of ​​tissue damage by 30%.
