Quantitative and real-time evaluation of pressure on brain spatula with wireless and compact sensing system

The brain spatula has been an essential neurosurgical instrument since the early 20th century, when medical advancements enabled surgeons to operate deep intracranially for the first time. Monitoring the brain retraction pressure, especially at an early stage of the intradural procedure, is useful i...
