As we all know, medical devices have higher requirements for processing and processing equipment due to their accuracy, stability, safety, purity and other characteristics. Especially in the process of metal medical equipment processing, the traditional sheet metal mechanical cutting processing mode has great defects in terms of accuracy and safety controllability. The following Leapion Laser introduces the application advantages of fiber laser cutting machine in the medical device industry.
1. Manufacturing medical equipment
One of the most important uses of laser cutting machines in the medical device industry is to manufacture medical equipment. An example is cutting high-end stents, which are used in devices such as birth control or pain control of kidney stones.
2. Precision tube cutting
Laser cutting can cut precision tubes; this is a very popular product in the medical industry.
3. Laser surgery
Lasers can cut skin and human tissues, which can be cut very quickly, cleanly and accurately, without causing thermal damage to the surrounding area.
Laser surgery is a better alternative to traditional methods such as scalpels, and you will also find that lasers are often used in procedures such as eye surgery.
4. Other uses
Used to manufacture vascular clips, valve frames, bone reamers, honing heads and flexible shafts.
1. The production process of fiber laser cutting machine is a non-contact process.
The laser cutting head will not contact the surface of the processed material, nor will it scratch the workpiece. For medical devices, a smooth surface is the most basic requirement. If the surface polishing process of the device product can be minimized in the processing process, the production efficiency will be greatly improved.
2. The smallest cutting seam of laser cutting ensures high cutting accuracy
The slits of the medical equipment produced by laser cutting are very narrow, the laser beam is focused into a small spot, the focal point reaches high power density, and the material is quickly heated to the degree of vaporization and evaporated to form a hole. With the relative linear movement of the light beam and the material, the hole continuously forms a very narrow slit, and the slit width is usually 0.10-0.20 mm.
3. The fiber laser cutting machine can achieve excellent edge quality for metal and plastic materials processing, making the laser cutting machine excellently applied to the heart, brain and eye stents (Nitinol and cobalt-chromium alloys), catheters, Heart valves and polymer tubes.
4. Fiber laser cutting machine can process cutting parts with small wedge angle and high aspect ratio. Compared with traditional laser processing, the thickness of the recast layer is significantly reduced in terms of slit width, slit wedge angle and recast layer.
5. The fiber laser cutting machine has the ability to freely adjust the pulse frequency and pulse period, and the controllability of cutting is obviously improved. Through metallographic inspection and observation of the laser cut section, the high quality of the cut can be confirmed.
6. The fiber laser cutting machine system can also use programs to process round, square or elliptical holes to help control the delivery of needles. Different types of microstructures can be processed on different materials, including metals, polymers, ceramics and glass.
7. Laser cutting generally uses nanosecond, picosecond or femtosecond pulsers to directly ablate the surface of the material without any post-processing procedures, and its heat-affected zone is extremely small. This process is very suitable for cutting blades, precision axes, brackets, clamps and hypodermic needles, etc.
During the global epidemic prevention and control period, the demand for medical devices has greatly increased. Medical devices are closely related to human life safety. The application of fiber laser cutting machines in the medical device industry escorts human life safety.
