Systems, apparatuses, and methods of and for an ophthalmic visualization system are disclosed. An example ophthalmic visualization system may include a first lens positioned relative to a surgical microscope in a manner facilitating viewing of a central region of a retina through the surgical microscope during a surgical procedure. The first lens may be positionable in an optical path between an eye and the surgical microscope during the surgical procedure. The example ophthalmic visualization system may also include a second lens selectively positionable relative to the surgical microscope and the first lens in a manner facilitating viewing of a peripheral region of the retina of the eye during the surgical procedure. The second lens may be selectively positionable in the optical path such that the peripheral region is selectively viewable without changing the position of the first lens during the surgical procedure.

Ophthalmic visualization devices, systems, and methods

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 fiber optic illuminator is provided comprising an optics bed, a light source, a collimating lens, and a condensing lens. The light source is mounted in a fixed position with respect to the optics bed. The collimating lens is mounted in a fixed position with respect to the optics bed and collimates at least a portion of the light from the light source. A condensing lens receives the substantially collimated light output and focuses the collimated light output to optically couple to an optical fiber. The condensing lens may be mounted on an adjustable mount. The tolerances of the fixed optical elements i.e. light source and collimating lens allow the fixed optical elements to be positioned with a minimal amount of variation where the variation is determined by manufacturing tolerances associated with these individual elements and their mounts and couple them to the optics bed.

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.

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 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.

A tray support arm assembly provides for the positioning of a tray and an attached movable arm in a substantially horizontal orientation with respect to the console portion of a machine for use and a substantially vertical orientation with respect to the console portion of a machine for storage. The tray support arm assembly includes a lockable tray rotation joint, a lockable wrist joint, a lower arm assembly, a lockable elbow joint, an upper assembly and a lockable shoulder joint.

Surgical console

A surgical console having a panel display mounted on a three-axis gimbel that permits articulation of the panel display via swivel, spin and tilt axes. The articulation mechanism uses two helix cable wraps with a single continuous cable that allows for large rotation of the panel display. The continuous cable simplifies construction and minimizes the electrical signal noise to the panel display.

Apparatus and methods for use in ophthalmic surgery in which a container for fluid is connected to a line through which fluid flows to a surgical handpiece for the irrigation of a patient's eye are provided. A sensor emits a magnetic field and a detector causes another magnetic field to be generated. The interaction of the two magnetic fields causes a pulse to be generated. Based on the timing of the generated pulse, the apparatus or method determines the absolute position of the support coupled to the container and adjusts the height of the support. Circuitry is also provided to prevent changes in height of the support by preventing supply of drive currents and by applying a hold current or by generating an electro motive force.
