Laser welding technology has greatly accelerated the development of medical devices. Compared with other commonly used welding technologies, laser welding technology hardly produces welding slag and debris, and there is no need to add any adhesive during the welding process, so the entire welding work can be completed in a clean room. Next, Leapion Laser introduces the application of laser welding machine in the medical device industry.
For example, there are: shell packaging of source implantable medical devices, radiopaque marking of heart stents, ear wax protectors, balloon catheters, etc.
1. Heart stent
The main material of the heart stent is stainless steel, nickel-titanium alloy or cobalt-chromium alloy. The molding process of the heart stent can use a laser with a minimum spot diameter of 40μm (0.04mm) to weld a disc-shaped marker into a special eyelet. The research and use of laser welding technology makes it possible to effectively connect two extremely small parts.
2. Balloon catheter
Balloon catheter laser welding is infrared welding that uses laser as the energy source. The laser beam can be directly directed to the surface of the plastic that absorbs the laser, so that the plastic can be melted and welded. Advanced laser welding technology can realize the seamless connection between the balloon tip and the tube body.
The introduction of laser welding technology is conducive to further reducing the outer diameter of the tip of the balloon dilatation catheter.
1. High welding quality
The laser welding machine has the characteristics of large welding aspect ratio, concentrated energy, and small heat-affected zone, which effectively solves the welding quality difficulties of medical equipment.
2. High welding accuracy
The motion axis of the laser welding machine is driven by a servo motor, using precision ball screws and linear guides as transmission elements, and the repeat positioning accuracy is ±0.02mm/300mm. The rotating shaft is driven by servo and the repeat positioning accuracy is ±10arc-sec, which effectively guarantees the strict welding accuracy requirements of medical equipment.
3. Sealed and safe
Adopting a structural seal design and a sinking layout of the power part, which effectively protects the safety of operators. At the same time, all materials used in the equipment have been strictly tested, and the materials used are environmentally friendly and hygienic, which can effectively ensure the anti-pollution requirements of high-clean production sites for medical devices.
4. Low cost and convenient maintenance
The laser welding machine has a small footprint and no additional consumables during operation, which is convenient to use. At the same time, it can be modified and upgraded according to customer needs according to local conditions, which can effectively save customers' operating costs.
In addition, the overall mechanism design of the laser welding machine is simple, which is convenient for shift cleaning, daily maintenance and maintenance operations.
5. The laser welding machine is a non-contact, clean, and absolutely dust-free joining technology. It has high stability laser output, high single pulse energy, high marking efficiency, maintenance-free operation, precise control, and extremely small welds. , Clean and environmentally friendly, it is very consistent with the corresponding welding requirements of the medical industry.
6. The laser welding technology hardly produces welding slag and debris, and there is no need to add any adhesive during the welding process, so the entire welding work can be completed in a clean room.
