1. A stereotactic positioning guide apparatus, comprising:
a positioning guide means, reversibly coupled with and operated by a positioning guide control means; the positioning guide means, provided in one or a plurality of mechanical configurations, which an invasive tubular device slidably passes through, which directs the invasive tubular device in a range of insertion angles to a tissue target, which rotationally adjusts and reversibly locks the insertion angle; and the positioning guide control means, provided as one or a plurality of operating devices having one or a plurality of mechanical and electronic configurations, which has a means to align a longitudinal axis of the invasive tubular device with the tissue target in an ultrasonographic visual field, which has a means to calculate the insertion angle of the invasive tubular device housed in the positioning guide means to reach the tissue target, which measurably and controllably adjusts the insertion angle of the invasive tubular device and which reversibly encloses a proximal portion of an ultrasound transducer. |
