Abstract:
A suction pressure control valve (SPCV) for microneurosurgery is designed to place control of safe suction pressure in the hands of an operating neurosurgeon. Tumor tissue needs more negative suction pressure as compared to normal brain tissue, cranial nerves, and vessels in the neurosurgical operating field. The authors present the details of a prototype of a simple and inexpensive device for dynamic adjustment of negative suction pressure by the surgeon or the assistant while working on different tissue types during microneurosurgery.
