Patna: AIIMS-Patna has developed an ultra-lightweight brain retraction device, the Saraj Retractor, marking a significant breakthrough in indigenous neurosurgical innovation. Conceived by additional professor, department of neurosurgery, Dr Saraj Kumar Singh, the device has received design registration from the Centre and trademark protection under AIIMS-Patna.Brain retractors are used during neurosurgery to gently hold brain tissue aside, allowing surgeons to access deep-seated tumours and other critical intracranial structures. Conventional systems typically weigh around 3.5kg, consist of multiple joints and components, and often require two to three operating theatre personnel for positioning and adjustment. Their complexity can increase preparation time, crowd the surgical field and raise the risk of mechanical failure.The Saraj Retractor weighs just 20 grams and features a streamlined single-joint design. According to AIIMS-Patna, it can be applied, adjusted and removed with one hand, reducing dependence on additional assistants while improving manoeuvrability during complex tumour surgeries. Its compact design is expected to minimise clutter around the operative field and help surgeons maintain stable exposure during delicate procedures.The device has been registered as a “Brain Cortex Separator Instrument for Neurosurgery”, while the trademark “Saraj Retractor” has also been formally approved. Officials said the development reflected the Make in India and Atmanirbhar Bharat vision by transforming clinician-led innovation into a potential commercial medical product.AIIMS Patna executive director Prof (Brig) Dr Raju Agarwal congratulated Dr Singh and said the device demonstrated how clinician-driven innovation could address real surgical challenges and improve patient care. He said the achievement strengthened the institute’s focus on research, excellence and indigenous medical technology.Dr Saraj Kumar Singh said the aim was to create a simpler, lighter and surgeon-friendly alternative to existing retractors, improving efficiency in operating theatres and supporting better outcomes in brain tumour and other neurosurgical procedures. The institute expects the device to see wider clinical adoption across the country.
