A robotic system helps to perform brain surgery

brain surgery robotic system

A neurosurgeon performing a keyhole neurosurgery makes a burr hole on the patient’s head for accessing the brain. Several conditions like hydrocephalus, Tourette syndrome, tumors, and epilepsy can be cleared by this process. During this operation, the neurosurgeon must be very careful because a small slip will cause a huge damage to the brain. To get rid of this problem, European Union’s ROBOCAST project has designed a robotic system for supporting the surgeon. It has been first tested with a dummy model, and now it is almost ready to employ on the real applications.

This robotic system incorporates two robots such as larger and smaller robots.

  • A larger robot is used for holding the smaller robot, which in turn helps the small one to be placed on the patient’s head at any point.
  • As it has six degrees of freedom, the smaller robot can be positioned anywhere in the three-dimensional area.

It also includes a microcontroller, a human-computer interface along with a haptic feedback control system, two field sensors, and an automatic trajectory planner. Additionally, it has optical trackers for observing the end of the probe and patient.

After positioning on the burr hole, the surgeon can use the smaller robot remotely for placing the surgical device into the brain with the help of optical trackers. An automatic trajectory planner can be handy in showing the movement of this surgical device, including the inside and outside part of the patient’s head. The sensors are used to adjust the robot position and power of the device. As a result, the surgeon has got the ability to control the device manually at any position.

Another upcoming project called as ACTIVE is capable of performing the robotic neurosurgical process even when the patient remains awake.
