There are several reasons why medical needles need picoseconds or femtoseconds laser matte black:
1. Visual recognition
Easy to distinguish: In the medical operation environment, the color of matte black forms a certain contrast with other medical instruments and the surrounding environment, which makes it easier for medical staff to quickly and accurately identify and pick up puncture needles, reduce operation time, and improve work efficiency.
Prevent mistaken picking: The unique color can avoid confusion with other similar but different functional instruments, reducing the risk of medical errors.
2. Reduce reflection
Avoid interference: The matte black surface can effectively reduce light reflection. When performing puncture operations, the medical staff's vision will not be disturbed by reflections, ensuring the accuracy and safety of the operation.
Protect patients: Especially in some patients who are sensitive to light (such as eye punctures) or areas that require precise operation, reducing reflections can reduce patients' discomfort and tension, and also help medical staff better observe the puncture site.
 

The principle of laser marking matte black is picosecond lasers or femtoseconds laser emit extremely short pulses of light (in the range of picoseconds, or trillionths of a second). This very short pulse duration allows the laser to deliver a high peak power to a very small area, which is crucial for detailed and precise marking
During the laser marking process, the energy of the laser beam is absorbed by the material, causing the temperature of the material surface to rise. When the temperature rises to a certain level, the surface of the material will vaporize or melt, forming tiny pits or protrusions. The size and shape of these pits and protrusions depend on factors such as the energy density of the laser beam, the irradiation time, and the properties of the material. By controlling the parameters of the laser beam, the size and shape of the pits and protrusions can be precisely controlled, thereby achieving accurate marking on the material surface.

LK laser picosecond marking machine and femtosecond marking machine can be used for marking medical threading needles. Laser matte black surface treatment on medical stainless steel increases the aesthetics and improves the corrosion resistance of the needle body, so that the medical needle can maintain good performance in various complex medical environments.
For different medical tubes, our machines meet different specifications and sizes, including different needle lengths and needle outer diameters. The marking scale is clear, which is convenient for medical personnel to accurately grasp the puncture depth.

Picoseconds /Femtosecond Laser Marking Machine 

Picosecond and femtosecond marking machines are widely used in blackening of puncture needles in various medical scenarios, including but not limited to the following fields:
Internal medicine: used for frosted blackening of chest puncture, abdominal puncture, pericardial puncture, etc., to extract effusion or perform diagnostic puncture.
Surgery: marking local anesthesia injection and puncture mark during surgery.
Obstetrics and gynecology: marking amniocentesis and ovarian cyst puncture marks.
Pediatrics: marking pediatric scalp vein puncture and bone marrow puncture scales.
