Tungsten Wire in Medical Surgery Application

Tungsten Wire - Unlock new usage scenarios!

Have you noticed that the incandescent light bulb has gradually faded out of our sight? But tungsten is still a hot character.

In fact, not only the lighting industry, tungsten wire also plays an indispensable role in a certain industry:

That is medical technology. Did you guess right?

Tungsten wire has always played an important role in medical equipment. Due to the characteristics of tungsten material, it has excellent working performance and gradually replaced stainless steel. In particular, it plays an outstanding role in controlling precision currents.

For example, in cauterizing medical surgery, tungsten wire can effectively reduce the bleeding and prevent tissue adhesion while removing the target tissue efficiently. The small tungsten wire provides great convenience for surgeons and patients.

From tungsten wire to tungsten cautery electrode

Cauteization is an essential surgical procedure to reduce potential or existing injury. The tungsten cautery electrode can effectively remove and seal the tissue, and has a very good effect of reducing bleeding and non-adhesion.

Another common type of surgery you might think, it is electrosurgery.

Electrosurgery usually uses an ultra-sharp metal probe, such as tungsten. When the probe tip is heated by an electric current to turn red at a high temperature, it could apply to the harmful tissue.

However, in cauterizing medical surgery, tungsten wires can be used as cutting tools in the form of pointed probe electrodes, ball probe electrodes, and loop electrode probes.

Tungsten does not deform. Even at such high temperatures, it remains intact and can effectively cut and cauterize tissue. This is due to its unique properties, high melting point, which stainless steel and titanium cannot do.

Tungsten electrodes for ablation devices

As an enduring character, it must adapt to multiple scenarios, including ablation equipment for minimally invasive surgery.

It is also high temperature to remove tissue. For example, in order to regulate the heart’s own electrical impulses and help regulate the heart rate, in cardiac ablation procedures, tiny sections of heart tissue are cauterized to achieve the effect and heal the patient.

Electrosurgery’s Best Choice

Tungsten wires are also used for probing and stimulation in electrosurgery.

Electrosurgery passes high-frequency current through a tungsten wire, allowing surgeons to precisely cut, coagulate, dry, or excise tissue without sticking the tissue while reducing blood loss. This method is used in a wide range of surgical procedures.

Electrocautery uses heat conduction from a probe heated by direct current, and electrosurgical devices use alternating current to directly heat the tissue itself.

Likewise, electrical stimulation (a procedure used in pain management and physical therapy) applies a device with tungsten electrodes directly to motor nerves or muscle fibers, via electrical impulses. As with electrocautery, the heat resistance of tungsten wire is a huge advantage in electrostimulation procedures.

Application of tungsten wire probe in neurosurgery

In order to be able to stimulate and probing better, the diameter of the wire probe must be very small and thin, and the tungsten wire probe is the best choice in neurosurgery. why?

For example, if you are making neural probes, there are three key issues:

The tungsten probe wire must be able to reach the target area at long distances without touching or disturbing the surrounding tissue.

Just like brain surgery, the smallest incision or opening possible. It needs to be accurate.

2. Smaller diameters and longer lengths of tungsten filaments than any other metal still retain their straightness and shape—properties critical to the directional accuracy of neural probes and similar devices.

3. For stimulation and probing purposes, the diameter of the wire must be very small and narrow, and the benefits of tungsten wire are obvious. For example, if you are making neural probes, there are three key issues:

Compared to any other metal, the small diameter and long tungsten wire still retains its straightness and shape—properties critical to the surgical precision of nerve probes and similar medical devices.

Additional Benefits of Tungsten Wire in Medical Devices

Do you think the benefits of tungsten wire electrodes are over? of course not.

The ductility of the tungsten wire makes it highly maneuverable as a guide wire in minimally invasive surgery. The same stainless steel ratio is not as good as tungsten.

Tungsten has a high density (comparable to gold), which makes it radiopaque. Therefore, there are other irreplaceable roles in minimally invasive devices.
