Combination stereotactic surgical guide and ultrasonic probe
First Claim
1. In combination:
- an ultrasonic probe to provide a visual image of a patient'"'"'s body; and
a surgical guide to be coupled to said ultrasonic probe to enable a needle probe to penetrate the body cavity of a patient at a particular location with respect to an organ or vessel of the patient undergoing treatment, said surgical guide comprising;
a clamp by which to detachably connect said surgical guide to said ultrasonic probe;
a plate for carrying a light source;
a light source coupled to said plate; and
position adjusting means interconnected with said plate to adjust the position of said plate and the light source coupled thereto,said position adjusting means operated to correspondingly move said plate relative to said ultrasonic probe until said light source coupled to said plate lies in spaced opposing alignment with the patient'"'"'s organ or vessel to be treated, said light source being energized to emit a light beam towards the patient'"'"'s body to establish a target thereagainst to indicate the place for the needle probe to penetrate the body to reach the organ or vessel.

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.
