An automated electronic microsurgical control system is disclosed which is capable of performing the various aspiration functions customarily performed manually by a surgical assistant. The system is entirely subservient to the surgeon\s foot control unit which is adapted to control seven different surgical functions. In addition, the electronic control system is designed to communicate audibly with the surgeon regarding actual fluid flow and the build-up of vacuum pressure in the aspiration lines connected to the microsurgical cutting instrument, thus permitting the surgeon to audibly ascertain complete information as to the actual activity within the aspiration line without requiring him to take his eyes from the operating microscope.

In an automated control apparatus for controlling a microsurgical instrument for performing infusion, aspiration and cutting functions of the type used in intraocular surgery, including a first source of infusion fluid hydraulically connected to an infusion line adapted to be connected to a microsurgical instrument, first valve means connected between said first source of infusion fluid and said infusion line for controlling the flow of fluid from said first source of infusion fluid to a microsurgical instrument, and pumping means connected to an aspiration line adapted to be connected to a microsurgical instrument for introducing a suction pressure into said aspiration line; the improvement comprising: foot switch control means electrically connected to said first valve means, said pumping means, and a microsurgical instrument, for controlling the actuation of said first valve means, the actuation and speed of said pumping means, and the actuation during the cutting mode of operation of said microsurgical instrument, in accordance with the positioning of said foot switch control means, said foot switch control means comprising a multi-position toe pedal switch and a multi-position heel pedal switch mounted to a pivotable base that actuates a first pivot switch when said base is pivoted in one direction and a second pivot switch when said base is pivoted in the opposite direction, such that either of said multi-position toe or heel pedal switches is actuable simultaneously with the actuation of either of said first or second pivot switches without requiring the surgeon to change the position of his foot relative to said pivotable base.
