According to media reports, David Comber, a graduate student in the Department of Mechanical Engineering at Vanderbilt University, and Eric Barth, an associate professor in the Department of Mechanical Engineering, will be able to become a new generation of brain surgeons, and the surgery performed by them will be shorter. Less damage and faster recovery. Although the robot's brain technology path may not be the shortest, it avoids the skull drilling, but uses cheek implantation.
It is reported that this machine system uses a shape memory alloy needle, which can remember the original shape, and when it is deformed, it only needs to be heated to return to its original shape. However, this system must be operated in an NMR machine in order to obtain a sufficiently strong magnetic field.
The shape memory alloy needle is made of a large number of concentric tubes made of nickel-titanium. This 1.14mm needle is like a mechanical pencil. Through MRI scanning, doctors can track the brain with an accuracy of 1.18mm. At the same time, Barth's associate professor of mechanical engineering, Robert Webster, developed a steerable surgical needle that coincides with Barth's brain surgery vision.
In addition, the team teamed up with Associate Professor of Neurosurgery, Joseph Neimat, to implant electrodes in the needle so that when the needle enters the brain, the patient's brain activity can be tracked to determine the exact location of the seizure.
However, the current robotic system is not yet able to perform a complete operation because the needle can only handle straight-through lines and still requires manual guidance by a doctor.
We, Jiangsu YanFang Medical Technology Co., Ltd, commenced our medical gloves manufacturing in 2020. Currently, we possess a total of 12 high-capacity NBR Glove Dipping Production Lines.
Likewise, we are not only certified with ISO9001, ISO13485 but also fully complied with the essential USFDA, CE Compliances, as well as obtaining relevant accreditation of FDA510K, EN455, and EN374.
Nonetheless, our NBR Examination, Chemotherapy, and Food Grade products are being well established in both US and Europe markets.
We look forward to cooperating and working closely with our valuable customers and stakeholders, who are seeking long-term business relationships in high-quality NBR glove supplies.
