What began as a compact 2D gaming device for those restricted in space is now being designed as a 3D surgery device for physicians restricted in mobility.

Sony’s modified HMM-3000MT headset (once called the HMZ-T2 gaming visor) is the next step in what the Japanese tech company believes to be safer, more precise laparoscopic surgeries.

Today, when surgeons are working with endoscopes, the feed is sent to a television monitor that remains in one location in the room. In order to keep track of the endoscope images, surgeons have to remain in a relatively restricted position and posture. By creating a wearable 3D headset, the operators could be freed from that constraint .

Sony is entering the field at a time when demand for 3D compatible endoscopes has risen due to their better precision and depth perception. Several medical device companies have already created their version of the technology.

The HMM-3000MT, however, has the benefit of learning from its gaming precursor. Manufacturers have improved the comfort and support of the visor. Previous reviews had commented on the neck, nose, and head strain sustained from long periods of use. Knowing the surgeons using their technology will be wearing the head-mounted displays for hours, Sony has included additional cushioning and straps that allow greater balance to the moving users.


In addition to making up for its previous shortcomings, Sony has augmented the successes of the video game version. It has enhanced the Picture-in-Picture options so that surgeons can view the endoscopy images alongside other transmitted patient data. It also allows the user to shift the picture right or left and even change the angle of view. This increased flexibility in point of view is projected to increase accuracy.

This product is fully approved in Japan and is awaiting approval to be used in other countries, including the US.
