Abstract
A variable pneumatic output device for use with ophthmalic micro-surgical instruments including a reversible servo motor which operates in response to instructions from an electronic control circuit. The rotatable drive shaft of the servo motor is operatively connected to the adjustable level control of a precision pressure regulator which operates between a fully open level and a fully closed level. The pressure regulator is operatively connected between a pressurized air source and the pneumatically driven micro-surgical instrument and according to the instructions of the electronic control circuitry, the servo motor, through the connecting drive to the regulator, adjusts the level of pneumatic output to the surgical instrument.
