  • Pneumatic controls for ophthalmic surgical system
    Patent number: 5979494
    Abstract: A pneumatic control system for providing pressurized air and vacuum to ophthalmic microsurgical instruments. The pneumatic system is constructed in a drawer assembly to allow it to be readily inserted into or removed from a modularly constructed cabinet of a microsurgical control console.In addition, the pneumatic system improves upon existing pneumatic control systems by providing a third mode of microscissors operation from a single pneumatic port. The third mode is made possible by a high speed three-way solenoid control valve which provides rapid pulses of air to the pneumatic port.A second improvement involves the use of a pneumatic pressure transducer to monitor pneumatic pressure being supplied to the pneumatic system in order to recognize non-hazardous transient drops in air pressure which can occur under certain normal operating conditions.
