ABSTRACT:
A stereotactic surgical guide to be coupled to the shaft of a conventional ultrasonic probe for use during cryosurgery to enable a surgeon to easily, efficiently and accurately position one or more cryosurgical probes in the body of the patient for producing iceballs to kill cancer cells at a localized tissue area. The stereotactic surgical guide includes a laser carrying plate that carries a laser and is coupled to a worm drive. The distance between the ultrasonic probe and the organ in need of treatment is visually determined on the monitor of an ultrasound machine, and the worm drive is rotated to cause the laser carrying plate to move a corresponding distance, whereby the laser will be positioned in spaced opposing alignment with the organ. The laser is then energized and a light beam aimed towards the patient's body to establish a target through which the cryosurgical probe will be inserted to penetrate the body.
