Apparatus for marking an operating site
First Claim
1. Apparatus for marking a predetermined position of a target for surgical treatment within a patient'"'"'s brain, comprising frame means for non-displaceable attachment to the patient'"'"'s skull and having at least one guide means extending along a first line, a first support member mounted to said guide means for adjustment along said first line and along a second line perpendicular to said first line, rotatable means supported on said first support member for rotation about a third line perpendicular to said first and second lines, a second support member extending parallel to said third line in spaced relation thereto and connected to said rotatable means for adjustment about said third line by rotation of said rotatable means, an arcuate support member mounted to said second support member for adjustment along said third line and for adjustment transversely of said second support member along an arcuate path defined by the arc of said arcuate support member, and laser light source means mounted to said arcuate support member for aiming a laser beam into the patient'"'"'s skull directly at the position of the target to provide guiding beam illumination of intervening tissue on a surgical path to the target as the surgeon proceeds to the target along said path and to mark the target when reached by the surgeon.

Abstract
Apparatus for marking a predetermined position of a target for surgical treatment within a patient'"'"'s brain, comprises a frame for fixedly embracing the patient'"'"'s skull and having at one side thereof a side-piece provided with a guide extending along a first line, a first support member mounted to the guide for adjustment along the first line and along a second line perpendicular to the first line, a rotatable member supported on the first support member for rotation about a third line perpendicular to the first and second lines, a second support member spaced from the third line and including an arm having a first end attached to the rotatable member and extending longitudinally parallel to the third line in a direction away from a side of the frame opposite the aforementioned one side, the arm thus being adjustable about the third line by rotation of the rotatable member, an arcuate support member mounted to the arm for adjustment along the third line and for adjustment transversely of the arm along an arcuate path defined by the arc of the arcuate support member, and a laser light source mounted to the arcuate support member for aiming a laser beam into the patient'"'"'s skull directly at the position of the target to provide guiding beam illumination of intervening tissue on a surgical path to the target as the surgeon proceeds to the target along the path, and to mark the target when reached by the surgeon.
