Laser Processing for Medical Devices

Aug 25, 2020

In the processing and application of medical devices, the traditional processing methods, such as plasma spraying, electrochemical deposition, sintering, etc., are not suitable for the processing of modern medical materials and medical devices because of its high temperature, high acid and high alkali processing environment. In contrast, laser processing has the advantages of low energy consumption, small damage, high accuracy, and strict 3D spatial positioning, which has a good application prospect in medical device processing. Due to the characteristics of high precision, high speed, non-contact cutting, and flexible processing, laser has become a common production tool in the medical device industry, which is used to cut, weld, and mark all kinds of conventional materials.

Laser Cutting

Laser cutting can make the workpiece surface smooth, reduce burr, and do not need subsequent processing. Due to its high flexibility, the laser can be used in different fields of the medical device manufacturing industry as much as possible. For example, when processing orthopedic implants, cardiac pacemakers, and other devices, the laser can completely seal and weld titanium metal shell without pores. Due to the good quality of cutting section, there is no need for subsequent processing, which saves time, labor cost and ensures the stability and safety of the device Sex. On the endoscope, the laser can also weld the thin tubes together, and cut the drilling holes and movable joints to ensure the precision and flexibility of the workpiece. At the same time, the precise quantitative laser pulse action area is small, which makes the thermal reaction zone of the workpiece small to ensure that the workpiece will not be distorted.

Laser Welding

Generally, the stability of the solder joint and the density of weld is very important when welding reusable medical devices. Laser can not only optimize the difficulties encountered in the traditional process, but also has high flexibility in the production process, and can meet the specific production requirements of small-batch and multi-batch in the medical device industry. At the same time, laser welding technology does not produce welding slag and debris in the welding process, and does not need to add adhesive. It can be said that laser welding technology has greatly promoted the development of the medical device manufacturing industry.

Many precise and small medical components, such as a cardiac stent, gastroscope biopsy forceps, ear wax protector, balloon catheter, and so on, are molded by laser welding technology. The research and application of laser welding technology make the effective connection of small parts in medical devices possible, which is the reason why laser welding is more and more widely used in the field of medical devices.

Laser Marking

Due to the particularity of medical products, there are strict quality standards in all aspects of production and processing. Therefore, the marking requirements of medical products are very high, and laser marking has become the preferred identification method. Laser marking with its permanent, accuracy and other advantages, has become a number of regular medical equipment and materials manufacturers for anti-counterfeiting marking of the preferred scheme.

In the manufacturing of medical devices, the uniqueness, traceability and anti-plagiarism of product identification are highly valued. The laser beam can produce the required marks, graphics or two-dimensional codes through the formation of fire color on the surface of metal materials or discoloration on the surface of plastic materials, and maintain a high resolution all the time. It will not damage the marks when the materials are sterilized at high temperatures, which has incomparable advantages compared with other processes. Compared with the traditional medical marking method, laser marking technology is not only more flexible in operation, but also more reliable and more creative space.
