CFRP brain surgery stent

In brain surgery, the stand used to fix the patient's head is usually made of metal. However, the metal itself is not easily penetrated by X-rays and will interfere with brain angiography and affect the doctor's interpretation. However, in order to ensure that the patient's head does not shake during brain surgery, the main fixed frame must ensure sufficient rigidity. The use of carbon fiber composite materials with a stiffness equivalent to or better than that of metal has less impact on the penetration of X-rays. In addition, carbon fiber is conductive but non-magnetic. carbon fiber tubes/pipes from frames can be easily assembled and also cost saving.
