Paralyzed man first to move his arm by thinking about it
Helping paralyzed people move on their own has been a lot tougher than 1970s TV shows led us to believe it would be. For what they believe is the first time, researchers used tech to bypass a quadriplegic patient's severed spinal cord, helping him move his own hand with his mind and feed himself without aid. The work could lead to "a new generation of neurotechnologies that we all hope will one day restore mobility and independence for people with paralysis," says research lead Leigh Hocherg.
High-tech scalpel makes brain surgery less risky
The "smart scalpel" developed by a researcher named David Oliva Uribe in Brussels, Belgium doesn't look or even work like a conventional scalpel. It has no edge, has a sensor-rich sphere at the tip, and instead of having the capability to cut people open, it can differentiate between cancerous tumors and normal brain tissue. A surgeon simply has to swipe it across the brain's surface to get a visual or an auditory result about the tissue's status in half a second. The tool's especially useful when locating early stage tumors, which still look similar to healthy tissue.
Patient wears VR headset to map brain during surgery
Virtual reality is becoming increasingly useful when it comes to the medical field, and doctors in France have taken notice. At Angers University Hospital in western France, physicians used a VR headset to map a patient's brain during surgery to remove a tumor late last month. The patient was conscious during the procedure (a common practice) in which doctors used a virtual environment to map zones of the brain. Until now, said mapping and monitoring neural connections in certain areas weren't easily achieved in the operating room.
Violinist fiddles with a smart bow to help his brain surgery
It's common for brain surgery patients to stay awake. That's how surgeons know everything is going smoothly, after all. When concert violinist Roger Frisch started suffering from tremors that are only a problem when he's playing, however, Mayo Clinic doctors had to resort to some rather unusual technology to find out if they were installing the necessary brain pacemaker correctly. The surgical crew gave Frisch a bow equipped with a motion-tracking sensor and asked him to fiddle during the operation; the team knew it had electrodes in the right spot when the musician's performance was steady.
Cranial Drilling Device puts a hole in skulls, not brains
If you told us on Monday that we'd be capping our week off by checking out an innovative cranial drill, we likely would have just stared at you funny. But here were are and here it is, a device referred to, quite straightforwardly, as the Cranial Drilling Device with Retracting Drill Bit After Skull Penetration. The drill was designed by a team of researchers at Harvard in order to address a major shortcoming with manual drills. Such devices require neurosurgical training in order to know precisely when to stop so as to not damage underlying brain tissue. In certain instances, such as emergency rooms and the backs of ambulances, medical practitioners may require a cranial drill in order to perform procedures such as the insertion of pressure monitors, with nary a neurosurgeon to be found. The Harvard team has concocted a drill that automatically retracts back into its protective casing, as soon as it's finished drilling through the skull, using a bi-stable mechanism that is active as the drill spins. After the break, team member Conor Walsh explains the technology is a manner that, thankfully, is not quite brain surgery.
Cybram 001 simulator helps doctors practice brain surgery without risking lives (video)
Sometimes it's awesome to be a guinea pig; take for example, getting down and dirty with the Consumer Preview of Windows 8. When it comes to brain surgery, however, there are no happy little accidents -- and let's face it, Bob Ross would've been a horrible surgeon. Thankfully, a new invention out of Japan promises to keep surgeons from taking practice swings at your noggin. Known as the Cybram 001, it's said to properly simulate the flow and pressure of one's arterial system from the cerebrum to the groin, and should allow doctors to gain greater familiarity with inserting surgical instruments into these delicate spaces. As the entire model is transparent, it's ideal for both students and instructors to see what's being done, and because variables such as blood pressure and heart rate can be adjusted, it's a useful simulator for different scenarios in the operating room. Not all of us will grow up to be brain surgeons, but if you'd like a peek into the frontiers of the field, just hop the break.
neuroArm gives surgeons extra dexterity, sense of touch
Considering that a BSOD within the robotic surgeon that's halfway through a critical operation on your innards is far from ideal, we're certainly in agreement with companies looking to make actual human doctors even better at their work. A team of Canadian scientists and engineers have concocted the neuroArm robot to allow doctors to perform microscopic operations on the brain in a more precise manner. Essentially, the uber-steady bot "will let doctors use surgical techniques on afflictions such as brain tumors that human surgeons are simply not dexterous enough to do," and when combined with a touchscreen stereoscopic viewer, it enables MDs to better visualize the area they're working with through advanced depth perception and "3D-like" imagery. The neuroArm system should hit clinical testing sometime within the next month or so, and if all goes smoothly (ahem), the long-term goal involves "manufacturing different versions" and selling them to a variety of hospitals.
