Laser production of surgical instruments

With lasers, you can not only precisely cut and weld surgical instruments and also provide them with ultra-smooth surfaces. Read here about the additional advantages laser technology can offer for the manufacture, processing and reprocessing of surgical instruments.

What are the challenges in the manufacture of surgical instruments?

Modular designs and different product variants make the manufacture of surgical instruments more difficult. Catheter systems, for example, are often difficult to handle because of their length. Other instruments and devices, such as endoscopes and laparoscopes, must frequently be cleaned and sterilised before they can be reused.

Temper marks are difficult to read after repeated reprocessing. In addition, the high temperatures and aggressive cleaning agents can damage the adhesive joints of the instruments. Such deficiencies in the medical instruments would be life-threatening for the patient during a surgical procedure. After all, given their usually small size, surgical instruments must also withstand high mechanical stresses.

What advantages does laser technology bring to the production of medical instruments?

Surfaces that have been processed by a laser are even and burr-free in their progression - without furrows or other major irregularities that could affect sterility. Laser weld seams on diagnostic instruments are also completely smooth and non-porous. This means that the seams have the same biocompatibility as the base material. Incidentally, additive manufacturing with laser technology can often be a viable alternative to the new production of small batches of medical instruments.

Lasers can automate applications for different materials

For a wide range of materials such as metals, polymers, ceramics and glass, work steps such as welding, cutting or surface treatment can be automated using laser technology.

Lasers manufacture robust products with strong joints and smooth surfaces

Laser manufacturing can be used to produce robust weld seams, surfaces and joints that can withstand even the most demanding uses and most aggressive cleaning agents.

Lasers are ideal for filigree and UDI-compliant markings

Laser technology is ideal for applying very filigree markings or UDI codes that offer maximum corrosion resistance and guarantee permanent legibility.

Lasers ensure the best possible sterility

Surfaces of instruments that have been processed by a laser do not show any blemishes that could affect sterility. In addition, laser welds are completely smooth and non-porous. As a result, they have the same biocompatibility as the base material.

What applications can lasers have in the manufacture of surgical instruments?

Lasers can be used in medical technology for both individual work steps and combined processes. Corresponding applications are, for example, cutting, welding and marking. This also makes it possible to optimise lasers for specific tasks and materials, enabling medical technology companies to respond to their customers' needs in production and manufacture customised, high-quality instruments.

Rely on solutions from TRUMPF in the manufacture of your medical instruments

With the expertise of the technology leader for laser technology with decades of experience in medical technology, we will be happy to advise you. Learn how you can use our laser systems and solutions to produce medical-grade instruments for surgical use.

Short-pulse lasers

Short-pulse lasers have a pulse duration in the nanosecond range and can be used in many processes in industry. They offer great flexibility in welding, drilling and cutting as well as in the ablation, cleaning and marking of medical instruments.

Ultrashort pulse lasers

Whether for structuring, cutting, drilling or ablating material, ultrashort pulse lasers are an indispensable tool for micro-manufacturing in medical technology. One of their special performance features is that they transfer almost no heat to the material (cold processing).

Automated multi-axis systems

In 3D manufacturing, automated multi-axis systems are often used for cutting, welding or surface treatment. These systems can be combined and configured with fibre lasers, disk lasers and ultrashort pulse lasers.

Marking lasers

With our marking lasers, you can achieve UDI-compliant markings with extremely good legibility. Find the perfect marking laser for your requirements: simply answer a few questions about your application and our product finder will show you which marking laser is right for you.
