摘要：
A neuro-vasculature access system and device for placing a cannula adjacent to a nerve. The neuro-vasculature access system and device includes a needle injector pivotally attached to an ultrasound transceiver which is operated to place a sterilizable needle or needle/cannula unit within the neuro-vasculature of a patient by a single user-device operator in which the neuro-vasculature is made visible in a monitor image by ultrasound insonification. A guidance template having an expected path trajectory is overlaid on at least one of a transverse short axis, a longitudinal long axis, or a three-dimensional image of the neuro-vasculature and predicts path of the needle or needle with overlapping cannula when it undergoes movement implemented by a controller located on the needle injector. The needle injector, ultrasound transceiver, and needle or needle/cannula unit may be contained within a flexible sheath capable of being sterilized.
