Claims5
A diagnostic instrument comprising, in combination:
- (a) a probe assembly including a pair of elongated flexible filaments, a tongued control member to which first ends of said filaments are secured so that they extend therefrom in the same direction, and a pair of cupped tips at the other ends of said filaments;
- and
- (b) a guide assembly having first and second apposed portions, one of said portions being extended and receiving the tongue of said control member and guiding it in a first, longitudinal direction, said portions being separately channeled to pass said filaments respectively so that they change directions by generally 90.degree. to extend laterally from one end of said guide assembly in opposite directions, whereby linear movement of said control member results in opposite motions of said tips along a line transverse to said guide assembly.
