An ophthalmic surgical system for filling a syringe with a retinal tamponading gas is disclosed. The system includes a surgical console having a user interface, a computer, first and second bottles containing pressurized retinal tamponading gases, and a port for fluidly coupling to an automatic gas filling consumable including a syringe. A user selects a particular retinal tamponading gas via the user interface, and the system fills the syringe.

Surgical console

A gas pressure monitor system for a pneumatically-powered surgical machine includes a first transducer, a second transducer, and a controller. The first transducer is located upstream from a filter and is configured to read a first pressure of a gas before the gas enters the filter. The second transducer is located downstream from the Filter and is configured to read a second pressure of a gas after the gas exits the filter. The controller is configured to compute a difference between the first pressure and the second pressure. A state of the filter is determined from the difference between the first pressure and the second pressure.

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.

A surgical console having bottles containing retinal tamponading gases and an automatic gas filling module disposed therein for filling an automatic gas filling consumable is disclosed. The automatic gas filling module includes a pair of gas shutoff valves and a regulator connected in series with a port for connection to the automatic gas filling consumable.

A system for providing pneumatic power to a vitrector includes first and second output ports, an output valve, an isolation valve, and three manifolds. The first and second output ports provide pressurized gas to power a vitrector. The output valve alternately provides pressurized gas to the first and second output ports. The isolation valve provides pressurized gas to the output valve. Two manifolds fluidly connect the output valve to the first and second output ports. A third manifold fluidly connects the isolation valve to the output valve. When the isolation valve provides pressurized gas to the output valve, the output valve operates at a high rate of speed to alternately provide pressurized gas to the first and second output ports thereby powering the vitrector.

Pneumatic system for a vitrector

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.

Adjustable pneumatic system for a surgical machine

A quick release filter assembly for a pneumatic module of a surgical machine includes a housing, an input port, an output port, a filter, and a flange. The housing has first and second sides, a top, and a bottom. The input port is located on the first side of the housing and is configured to permit gas to enter the housing. The output port is located on the second side of the housing and is configured to permit gas to exit the housing. The filter is located in the housing between the input port and the output port. The flange is rigidly connected to the housing along a periphery of the top of the housing. The flange extends outward along a plane generally parallel with the top of the housing. The flange has a mechanism for connecting the housing to a mounting portion of the pneumatic module. When the mechanism is disengaged, the filter assembly can be removed from the pneumatic module.

A connector includes a rear body portion and a front body portion. The front side of the rear body portion, and the front body portion disposed therearound, are for fluidly coupling to first and second sources of pressurized fluids in a co-axial manner. The rear side of the rear body portion is for fluidly coupling to first and second destinations of the pressurized fluids in an adjacent manner.
