In brain surgeries, precision is everything — a shift of a few millimetres can make the difference between a successful surgery and putting a patient in coma. One device that improves the accuracy of neurosurgery is the stereotactic head frame, which provides a 3-dimensional coordinate system to help surgeons get the precise location of a nerve or tumour in the brain.

However, the device currently used is prohibitively expensive, costing between 75 lakh to 1 crore. A Benguluru-based doctor has designed a low-cost stereotactic frame which can be used to operate on both sides of the brain at a time, unlike conventional frames currently used in hospitals. The frame designed by Dr. Murali Mohan, senior neurosurgeon with BRAINS Sparsh Hospitals, is made of medical grade titanium and costs one-third the current price.

The frame which is CE marked (it conforms to European standards) and is pending patent, is currently being used by a doctors in around six to seven hospitals in Bengaluru and Hyderabad for biopsies and deep brain simulations.
