The new nano camera sits on a needle tip that is only 1.9 mm in diameter.

Inside the needle there is also a light source and a channel that is used to inject liquids.

According to Daniel Reiser at USÖ, the new camera has many advantages, compared to the cameras that were previously used in arthroscopy (peep hole operations).

The small tube, only 1.9 mm thick, houses the camera, lighting and a flushing channel.

The camera is a disposable product.

The advantages compared to a magnetic camera and traditional arthroscopy examination are several, according to Daniel Reiser.

- In the past, cameras with larger glass lenses have been used.

The problem with that is that glass is fragile, you can't make the glass any thin.

Therefore, a slightly larger operation was always required when looking into joints.

This new technology is much less complicated and more efficient.

More patient safety

But there are also other benefits with the new method that is now being used at Örebro University Hospital.

- We avoid putting patients to sleep unnecessarily because the vast majority of patients who come here do not need to have a major operation afterwards.

In this way, it also becomes more patient safe.

Can have more uses

Currently, the camera is only used to diagnose ligament damage in the wrist.

However, Daniel Reiser is convinced that nanotechnology will become widespread in the future.

- For example, our orthopedic colleagues will start with this to locate ligament damage in ankle joints.

And the technique can also be used in the diagnosis of shoulder injuries.

So I absolutely believe that this method will spread and not just be limited to hand surgery.
