Devices, systems, and associated methods that facilitate the injection and/or aspiration of precisely controlled volumes of fluids at precisely controlled rates are provided. In some implementations, an apparatus may include a syringe and a lead screw connected to a plunger of the syringe. A ratchet gear may be connected to the lead screw. A mechanism may also be included to oscillate a frame in a direction perpendicular to a longitudinal axis of the lead screw such that one or more pawls of the frame engage the teeth of the ratchet gear in a manner that results in rotation of the ratchet gear in a single direction for controlled linear displacement of the plunger.

Micro-volume devices, systems, and associated methods that facilitate the injection or aspiration of precisely controlled volumes of materials at precisely controlled rates are provided. In one embodiment, a micro-volume device includes a syringe and a lead screw connected to a plunger of the syringe. A mechanical interface is connected to the lead screw and includes a first set of cams adjacent a proximal portion and a second set of cams adjacent a distal portion. A mechanism is configured to oscillate a structure in a direction parallel to a longitudinal axis of the lead screw such that one or more projections of the structure to alternatively engage cams of the first and second sets of cams in a manner that results in rotation of the mechanical interface in a single direction for highly controlled linear displacement of the plunger.

Provided herein is an illuminated microsurgical instrument system and an illuminated microsurgical instrument. In one implementation, the system includes a microsurgical instrument having a distally projecting tubular member arranged to perform a medical procedure at an interventional site. The tubular member has a distal tip and an outer surface, the outer surface having a flat surface formed therein. The instrument includes a sheath member surrounding a portion of the tubular member and extending toward the distal tip of the tubular member and an optical fiber extending along a length of the flat surface between the tubular member and the sheath member. The instrument may further include a slack chamber, collar structure, and fiber guard member to support and guide the optical fiber to the distal tip.

A scanning optical probe and method includes a cannula, optical fiber, lens, and an actuating mechanism for tilting the optical fiber back and forth within the cannula. An actuator in the probe handle is coupled to various flexing and guide components extending through the cannula and towards the distal end of the scanning optical probe. Reciprocating motion from the actuator is transmitted to the components thereby causing the optical fiber at the distal end of the scanning optical probe to aim across target surfaces. The light emitted from the optical fiber is processed to generate a scan of the target area.

An ophthalmic cannula assembly may include a cannula having an outer cannula surface and an inner cylindrical bore. A hub adjoining a proximal end of the cannula may define a maximum outer hub diameter that is greater than an outer diameter of the cannula. An optical fiber may be attached to the outer cannula surface for at least a portion of a length of the cannula. A cover material may be in contact with the outer cannula surface, and may cover at least a portion of the optical fiber. A light diffuser may be disposed at a distal tip of the optical fiber.

An illuminated microsurgical instrument is provided herein that includes a microsurgical instrument having a tubular member arranged to treat patient tissue at a surgical site, the tubular member having a distal tip, an inner surface, and an outer surface. The inner surface defines a lumen. The outer surface has a notch formed therein. The illuminated microsurgical instrument further includes an optical fiber arranged to deliver light to the surgical site. The optical fiber includes a proximal end arranged to receive a light beam from a light source and also includes a curved distal end arranged to emit light adjacent to the distal tip. A portion of the curved distal end is positioned within the notch and curves away from the tubular member.

Devices, systems, and methods that utilize at least one charged electrode to impart motion to an optical fiber positioned within an imaging probe by an electrostatic force are provided. In some embodiments, an ophthalmic imaging probe can include a handle; a cannula coupled to the handle; an optical fiber positioned at least partially within the handle and the cannula, the optical fiber configured to receive an imaging light from an imaging light source and guide the imaging light to an optical element positioned within the cannula; and an actuator system configured to impart motion to the optical fiber, the actuator system including an electrode positioned within the cannula and configured to impart motion to the optical fiber by selectively imparting an electric charge to the electrode and/or the electrically conductive layer of the optical fiber.
