Abstract

A portable stereotactic guidance having coordinated targeting and delivery assemblies. Aligning and orientating a medical instrument in a three-dimensional plane by specific cartesian coordinates or live imaging. The device may operate in conjunction with an X-Ray or CT scanner so as to image a patient allowing the surgeon to accurately introduce a probe such as a needle, cannula, or guide wires into the human body at a preselected angle. The device fits over a patient using and is used in conjunction with an alignment guide to read X, Y and Z coordinates as well as associated angles for precise orientating of a delivery system. Provision is made for aligning of the device can be performed during real time X-Ray or scanning through a target assembly having cross hatching to target an object for use as a reference point. Once a target is set, the delivery system is aligned by sliding the delivery system within a cartesian coordinate system thereby rotating the stir ups along a polar coordinate system. The delivery system can be aligned by rotation of the stir ups to either specified angels or desired images. The delivery system can be used independently from the targeting system.
