In May, a news shocked the world. A top Italian neurologist named Sergio Canavero is ready to have a spinal muscular atrophy at the end of 2017. The Russians are doing "head-changing". It is worth noting that this operation will use the most popular VR technology.
It is not known how Sergio Canavero will use VR during surgery, but the medical industry and VR "hook" together have a long history. The sci-fi film "Magic Journey", released in 1966, describes several doctors who even reduced the size of a submarine to less than a millimeter into a scientist's blood vessels to view and repair his brain. Today, the scenes in science fiction movies have finally come true.
At the end of September, the University of Oxford released a groundbreaking study that used VR technology to simulate crowded subways and elevators to improve the condition of people with confined space phobias.
The principles behind this treatment technique are actually not new. In theory, if you are afraid of something that is not really harmful (such as social phobia, spider phobia, etc.), then the doctor will let you gradually touch this kind of thing, slowly let you become used to it, until You can face this kind of thing without any pressure. Although some patients have received such treatment before (for example, for a socially feared patient, the doctor may let him chat with three strangers in a course of treatment), but the advantage of VR is that it can simulate some difficult to move into the treatment room. Scenes (such as those who are afraid of flying, those who are afraid of spiders), and therapists can use their experience to guide patients in a VR environment.
Obviously this is not a new treatment, but with the rise of VR helmets such as Oculus Rift and HTC Vive, VR devices are becoming more affordable, and the possibility of large-scale adoption of this treatment has become more The bigger it is. For example, Firsthand has developed a number of VR applications over the past 20 years, from mitigating spider phobia to cultivating good oral hygiene habits for children.
Here are some other uses of VR in the medical field:
Use VR to relieve phantom limb pain
The medical profession is still not fully aware of the causes of phantom limb pain, but two-thirds of amputees are affected by phantom limb pain. In short, they feel that they have lost part of their body's severe pain, sometimes to the point where they can't sleep and affect their daily lives.
Dr. Max Ortiz Catalan of Chalmers University has greatly improved the symptoms of phantom limb pain in Swedish amputee Ture Johanson. Johnson lost half of his right arm in a car accident. The doctor asked Johansson to play an AR game in which the patient can use real-world motion to control the motion on the screen.
“There is a point that after the patient’s amputation, the 'body map' in the brain changes. This means that the amputee (whether it’s the limbs, the breasts, or the nose) may have phantom limb pain. Therapy is to restore the original map in the brain and let the patient use the missing limbs to get rid of the pain," Dr. Catalan said.
