Surgical robot to enter brain through patient’s cheek

Team leader, Eric Barth, associate professor of mechanical engineering at the University of van der Burg, and David conber, a graduate student in mechanical engineering, designed most of the machines, which was released last week at the FluidPower Innovation and Research Conference.
The team conducted a live demonstration of surgical techniques at the theNashville conference in Tennessee.
Entering the brain through the patient\'s cheeks is not a new procedure, as neuroscientists approach planting electrodes in the brain to track brain activity and determine the source of seizures.
But the straight needles they used were not able to reach the source area, so they had to go through the seagulls and insert the needles used to destroy the head\'s misbehaving neurons, the scientists said in the statement.
So the van der Bildt engineering team decided on a new approach: designing a shape
Memory alloy needles-that is, an alloy that is able to remember its original shape and return to it after deformation-can run along a curved path.
According to CNET, they also want the robot to be able to operate inside MRImachine, which means it cannot be made of magnetic metal due to the strong magnetic field of the device.
Prototype 1. 14 mm nickel-
Titanium needles that work like mechanical pencils.
It has concentric tubes, some of which are curved, allowing the tip to enter the brain along a curved path.
Using compressed air, the robot platform can push the needle segment to millimeters while the surgeon tracks MRI t for progressive MRI scans, scientists explained.
The project started five years ago when Barth worked with another associate professor of mechanical engineering at the University of van der Burg, Robert Webster, to combine their capabilities already under separate research.
\"In my career, I have done a lot of work on the control of pneumatic systems,\" Barth said in a statement . \".
\"We know that we have the ability to install robots in an MRI scanner and do something in a way that other robots can\'t do.
Then we thought, \"What can we do to make the biggest difference ? \" \"One day, when Eric and I were talking in the hallway, we came up with the idea that we thought he was in the environment of expertise in pneumatic, it can be combined with the manageable needles I \'ve been working on, Webster said.
After discussing with Joseph nimart, an associate professor of neurosurgery at the school, the two professors determined that surgery to prevent seizures is an ideal application.
Seizures originated in the hippocampus, which is a deep
According to the MED Device online, the seat area of the brain is difficult to access in a regular way.
In the most serious cases, seizures cannot be controlled by drugs and surgery is required to stimulate, disconnect or remove that part of the patient\'s brain.
At present, high
The risk procedure is long, invasive and needs to be drilled into the skull.
If the operation is successful, the patient will face three
Monthly recovery period.
\"The systems we have now allow us to introduce probes into the brain-they handle straight lines and only conduct manual guidance,\" Neimat said . \".
\"Having a system with a curved needle and unlimited access will make surgery minimally invasive.
We can do a dramatic operation, just stick it on the cheek.
Scientists said: \"Many parts of the robot are made using 3D printing, which makes the cost of the project very low.
They worked with Jonathon Slightam and Vito Gervasi from themil engineering School of engineering, who specialize in new applications for additional manufacturing.
Barth said the project is now moving into the next development phase, which is being tested on the corpse.
He estimates that surgical robots may be in the operating room in the next decade.
