Remote-controlled microrobots could be the future of medicine

Tiny robots might soon replace invasive surgery.

This robot sutures surgical incisions like a STAR: it’s better than doctors

Thanks to robots, surgery has gone a long way since these have been introduced in the ’80s making operations safer and less invasive. Now, surgical robots are starting to migrate from assistant to leading roles, which is where experts say they will really shine.

Using origami, scientists are making the smallest surgical tools yet

Mechanical engineers at Brigham Young University are combining the versatility of origami with mechanical know-how to produce the smallest surgical tools.

Using ultrasound to operate on the brain

A preliminary study from Switzerland, published this month in the Annals of Neurology, proved the effectiveness of a new method of non-invasive brain surgery: using a newly-developed operating device that relies on ultrasound, in conjunction with magnetic resonance imaging (MRI), allowed neurosurgeons to precisely remove small pieces of brain tissue in nine patients suffering from chronic pain without removing skin or skull bone. Researchers now plan to test it on patients with other disorders, such as Parkinson’s. Neal Kassell, neurosurgeon at the University of Virginia, not directly involved in the study.

Watch this robotic surgical system stitch a grape

With grace and steady robotic clippers, this high-end remote controlled surgical system was used to stitch a piece of skin back over the exposed flesh of a grape. Like a pro, the Da Vinci Surgical System – named after the famous renaissance genius who first inspired working robots – can be seen in this amazing video putting the final touch, tying a knot, then using its scissor-hand to cut the loose thread. Job done!

Neither dead or alive: the suspended animation trial

For the half-dead arriving at hospitals, like the unfortunate who suffer gunshot wounds or lose a lot of blood some other way, there’s very little doctors can do. There are so little life saving procedures and surgeries that can be performed, and doctors need their patients at least a few more hours to be alive for most of these to

Sensitive robots to dramatically improve machine-assisted surgery

More than on one occasion, the Enterprise’s chief medical officer Dr. Leonard McCoy laments how barbaric surgeons of the XXth century must have been to actually cut patients during surgery. While many of Star Trek’s memorabilia are far from having become reality, medicine has made important strides forward in some aspects comparable to Doc. McCoy’s methods. A working tricorder might

Most comprehensive face transplant patient doing well after seven months

A while ago I reported about one of the most astonishing medical stories, when Richard Lee Norris, a terribly disfigured young male, received the most comprehensive face transplant in history. During the procedure, both jaws, teeth, facial soft tissue from the scalp to the neck and sensory muscles indispensable to facial expression were replaced. After seven months the results are staggering,

Surgeons perform most extensive full face transplant, including jaws, teeth, tongue and facial muscles

Plastic surgeons at University of Maryland performed the most complex facial reconstruction surgery to date, which included the replacements of both jaws, teeth, facial soft tissue from the scalp to the neck and sensory muscles indispensable to facial expression. The procedure was part of a 72 hour transplant marathon, aftern an anonymous donor generously donated his face and organs in

Revolutionary wireless powered tiny device can swim through blood streams

Implantable medical devices, capable of delivering drugs or performing micro-surgery from inside the body, have been the subject of scientific research for decades now. A number of exciting prototypes have been developed in the past few years, as miniaturization allowed it, however reliability flaws rendered them unpractical. A new tiny device developed by Stanford electrical engineers, was presented this week at the International Solid-State
