An improved consumable for use in a fluid/gas exchange in vitreoretinal surgery. The consumable includes a syringe having a barrel with a first opening for receiving a retinal tamponading gas, a stopper slidably disposed within and fluidly sealed to the barrel, a plug assembly, and a plunger. The stopper has a relief valve for venting air and retinal tamponading gas to atmosphere via a hollow bore in the plunger.

A smart connector system includes a machine connector disposed on a face of a surgical machine, an illumination ring located on the face of the surgical machine and disposed around a periphery of the machine connector, an RFID reader antenna located in close proximity to the machine connector and the face of the surgical machine, and an accessory connector adapted to couple with the machine connector. The accessory connector has an RFID tag antenna and is capable of attaching a tool to the surgical machine. When the accessory connector is brought within close proximity to the machine connector, a communications connection is established between the RFID tag antenna and the RFID reader antenna.

Embodiments of the present invention provide top and bottom clamping of a surgical cassette. One embodiment of the present invention includes a surgical cassette adapted for use in a surgical system having a first side (e.g., an inner side) and second side (e.g., an outer side). The surgical cassette, according to one embodiment, comprises a body portion configured to interface on its first side with a surgical console during use, a first clamping portion projecting from the top of the body portion configured to contact a first clamp rail on the cassette's second side during use and a second clamping portion projecting from the bottom of the body portion configured to contact a second clamp rail on the cassette's second side during use.

Embodiments of the present invention provide an apparatus and method controlling the flow of aspiration fluid in an aspiration chamber of a surgical cassette. One embodiment of the present invention provides an aspiration chamber having an aspiration port positioned at or close to the bottom of the chamber. When the aspiration fluid enters the aspiration chamber from below the fluid surface (e.g., from a port located at the bottom or on a sidewall close to the bottom), it does not create disturbance at the liquid/air interface and thus does not disturb the continuous level sensing. Also, since the aspiration port is placed at or very close to the bottom of the aspiration chamber, the liquid inside the chamber can be fully used for sustained reflux and push priming.

A pneumatic system for a surgical machine includes a reservoir, first and second proportional valves, and a controller. The reservoir holds pressurized gas. The first proportional valve is located on an input side of the reservoir and allows a variable amount of pressurized gas to enter the reservoir. The second proportional valve is located on an output side of the reservoir and allows a second variable amount of pressurized gas to exit the reservoir. The controller controls the operation of the first and second proportional valves. The controller adjusts the first and second proportional valves so that a constant gas pressure range is maintained at an output of the reservoir over a first range of input gas pressures and a second range of gas usage.

A system for a pneumatically-powered vitrectomy machine includes an output port, a venting valve, a venting manifold, a pressure transducer, and a controller. The output port provides pressurized gas to a vitrectomy probe. The venting valve is located close to the output port. The venting manifold fluidly connects the venting valve to a venting port. The venting port vents pressurized gas from the venting manifold. The pressure transducer is located near the output port. The pressure transducer is configured to read a pressure of a gas near the output port. The controller is adapted to receive information about the pressure and activate the venting valve. When the information received from the pressure transducer indicates a fault condition, the controller directs the venting valve to open.
