Robots swim in blood vessels

In the near future, when doctors say that this case needs surgery, the patient is not too worried.

Because the physician may not move much of the knife that the work is done by a small robot. The breakthrough in this treatment comes from Stanford University (USA). It is a device that can swim in a vein that doctors control wirelessly through electromagnetic waves outside the patient's body.

Previously used robot robots needed energy because of the large battery packs, so far their size has been reduced by the grain of rice. This type of device can travel to the place where the medication is needed exactly for the body part, rather than the whole body absorption as the classical way is to drink or inject drugs with many side effects.

They can also perform very delicate surgery or missions and then send the image out, replacing the current invasive colonoscopy. The prototype of this versatile multipurpose robot is 3 x 4mm and the future is even smaller.

In early April 2012, Professor Ada Poon demonstrated the effectiveness of new robots at the International Symposium on Applied Microvasculature. They can either be self-propelled or wirelessly controlled outside the patient's body. According to Professor Ada Poon, this type of equipment meets many requirements. They are a revolution in medical technology, ranging from drug therapy to diagnostic or minimally invasive surgery. According to the Daily Mail, Ada Poon's latest robot can "wander" in blood vessels, deliver drugs to specific sites, perform disease analyzes and even spectacularly eliminate clots or types. Remove the plaque in the arteries of the sclerosis.

The secret of this new generation of surgical robots is that it is operated via wireless radio waves, which is also the source of the energy that it can travel through the blood stream.
