Abstract

The present invention provides a surgical system 10 for aspiration of a biological material comprising a source of irrigation fluid 24 , a collection cassette 30 , a pump 40 for creating a vacuum in the collection cassette 30 , a handpiece 50 applied to a surgical area for infusing irrigation fluid and for aspirating a biological material, conduits 60 and 62 connecting the handpiece to each of the source of irrigation fluid and the collection cassette, and means 70 for stopping the pump and preventing creation of vacuum within the conduit 62 and collection cassette 30 after receiving a stop signal.

Claims (6)

1. A surgical system for aspiration of a biological material comprising a source of irrigation fluid; a collection cassette; a vacuum pump having momentum-generating motion for creating a vacuum in the collection cassette; a handpiece applied to a surgical area for infusing irrigation fluid and for aspirating a biological material; a conduit connecting the handpiece to each of the source of irrigation fluid and the collection cassette; and a brake configured to apply mechanical resistance to stop the vacuum pump momentum-generating motion to prevent creation of vacuum within the conduit and the collection cassette after receiving a stop signal.

2. The surgical system according claim 1 , further comprising a controller connected to the brake to monitor the pressure of the aspiration conduit and send a stop signal.

3. The surgical system according claim 2 , wherein the controller is a surge-flow regulator that monitors the pressure of the aspiration conduit and sends a stop signal to both the pump and the brake upon reaching a pre-determined pressure.

4. The surgical system according claim 1 , further comprising one or more pressure relief valves.

5. The surgical system according claim 4 , further comprising a controller connected to the brake, wherein the controller sends a mechanical or electronic stop signal to the pump and the brake the pump and makes the pressure relief valves open upon sensing a pre-determined pressure.

6. The surgical system according claim 1 , wherein the surgical system is for ophthalmic surgery and the handpiece is a phacoemulsification handpiece applied to a patient's eye.
