A biological tissue cutting and fluid aspiration system provides a plurality of surgical instruments operable independent of an external control console. In some embodiments, each surgical instrument may include all sensors and controls directly applicable to the surgical instrument, and may be used independently. In some embodiments, instruments communicate status information to each other, and adjust operating parameters based on the communications.

Independent surgical center

A first light source producing a first light beam with a first intensity and a second light source producing a second light beam with a second intensity. A light filter device receives the first light beam and transmits a filtered portion of the first light beam. A first angling device reflects the filtered portion of the first light beam in a first angled direction and a second angling device reflects the second light beam in a second angled direction. A mirror receives and in turn reflects the filtered portion of the first light beam reflected by the first angling device and the second light beam reflected by the second angling device to form a converged light beam with a third intensity.

Enhanced visualization illumination system

Various adjustable cannula systems are provided. The systems can include an adjustable cannula capable of expansion and/or contraction having an elongate body with a distal end and a proximal end. The adjustable cannula can be coupled to an upper housing and a lower housing such that rotation of the upper housing results in expansion or contraction of the adjustable cannula. The adjustable cannula can also have a proximal end having a lumen larger than a distal end lumen. A plurality of flanges can be formed in the elongate body by a plurality of slits that span a majority of a length of the cannula, including along or proximate to its proximal end and distal end.

Adjustable cannula systems and devices

A sterile surgical tray includes structure for receiving a plurality of surgical instruments. The sterile surgical tray also may include electrical input and output connectors attached to tray.

Sterile surgical tray

A cannula is described having a housing, a first lumen, a second lumen, and a port capable of fluid communication with the first lumen. The second lumen configured to receive fluid from the first lumen and to direct the fluid to a surgical site. A light emitting diode light source is positionable within the housing and configured to direct light through the second lumen to the surgical site.

Self contained illuminated infusion cannula systems and methods and devices

A sterile surgical tray includes structure for receiving a plurality of surgical instruments, a pump fluid reservoir within the tray, a pump contained within the sterile tray and connected to the pump fluid reservoir, and a motor contained within the sterile tray and connected to the pump. Sterile surgical trayalso may include electrical input and output connectors attached to tray.

A portable surgical tray unit can include a portable surgical tray for housing a processing unit, and that includes an opening extending entirely therethrough. The portable surgical tray unit can also include a plurality of instruments connected to the portable surgical tray and operably coupled to the processing unit, and a user input device positioned on at least one of the instruments. The user input device can be operably coupled to the processing unit and can be configured to receive a user input for controlling an operating parameter of one or more of the instruments. The processing unit can be configured to receive user input through the user input device and transmit an operating command to the one or more instruments. The portable surgical tray and the plurality of instruments can be sterilized and prepackaged in a single package.

Illumination systems are described that can include one or more light sources, which can include LEDs, one or more lenses, and one or more optical fibers. A handheld, portable, and surgical intraocular illumination system is disclosed that is disposable, low-cost, and efficient. A surgeon can have direct control of turning the illuminator on and off and adjusting the intensity via a simple control ergonomically placed on the handpiece and/or voice activated control. A coupling is provided, such as through an endo-probe, which is coupled to the one or more light sources. A user input device can be included that is operable to transmit to a feedback controller a first signal based on a user-selected light intensity. The feedback controller can, in response to the first signal, transmit a second signal to the power source for altering the power provided by the power source to the illumination system.

Portable handheld illumination system

Apparatus, systems, and devices are described that utilize an adjustable biological tissue cutting handpiece that is based on selectable settings. The biological tissue cutting handpiece includes a cutter tip that allows multiple duty cycles as well as multiple port configurations. For example, when working next to the retina, the port could be adjusted to be a smaller size, allowing delicate membrane dissection. When working near or in less sensitive tissue, e.g. the center of the eye, the port could be wide open. The port aperture size can be independent of cut speed, allowing a surgeon to work at high speed both next to the retina and away from the retina. High speeds have been shown to have increased tissue (e.g., vitreous) removal, e.g., in 25 and 23-gauge instruments. Duty cycle is not necessarily dependent on cut speed, allowing high cutter performance and varied flow characteristics.
