The disclosure herein provides methods, systems, and devices for a sterile ophthalmic surgical drape system that can provide a sterile operating field for use by a doctor, surgeon, nurse, and the like during ophthalmic medical procedures. The sterile field created by the drape system can allow a doctor, surgeon, nurse and the like to perform a medical procedure, such as ophthalmic surgery, outside of an operating room and in locations such as a doctor's office or a military operating room war setting. The sterile ophthalmic surgical drape system can comprise a drape, a frame apparatus, a hole of sufficient size for a microscope, a fan, a filter, air directors, and slits. The drape system can comprise a collapsible frame apparatus. The drape system may be configured to be used in conjunction with a surgical tray that houses pre-sterilized tools for use in a medical procedure.

Sterile surgical drape for ophthalmic surgery

Ocular lens cutting devices and methods for cutting and removing tissue such as lens fragments from an eye of a patient are disclosed. In one embodiment, an ocular lens cutting device includes an outer member and an inner member positioned within the outer member. The outer member and the inner member can each include at least one cutting edge. The at least one cutting edge of the outer member and the at least one cutting edge of the inner member can cooperate to form a cutting structure as the inner member moves with respect to the outer member. The ocular lens cutting device can also be connected to a vacuum source which can allow the ocular lens cutting device to grasp the tissue to be cut and remove the cut fragments from the surgical area.

Ocular lens cutting device

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 surgical apparatus for use by a surgeon can include a tray and a plurality of surgical instruments. The tray can have a plurality of structures located on an upper side of the tray for receiving the plurality of surgical instruments. The tray can receive a separate control unit. The tray can also have a fluid reservoir receiver for receiving a bottle or container of fluid, such as balanced salt solution. The fluid reservoir receiver can include one or more features, including, a spike, an air vent, and a light. A separate container can be used to place the bottle or container of fluid into the fluid reservoir receiver on the tray. This separate container can include a collapsible section.

Sterile surgical tray

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.

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.
