ABSTRACT:
A multi-jointed support arm accepting various Ophthalmic instruments and platforms is suspended by cables distributing the weight of said arm and instruments up and over two sets of pulleys and back down to a counterweight. A switch actuated electro-mechanical lock prevents accidental descent of the instrument platform support arm. Upward movement of the support arm is unrestricted. An outer shroud conceals mechanical components of this device prior to the support arm.
