20090182313 | Targeted Illumination For Surgical Instrument - An illuminated surgical instrument has a working area located near an end of the instrument. An array of optical fibers terminates near the end of the instrument. The array of optical fibers is located adjacent to the instrument such that the array of optical fibers provides targeted illumination to the working area only on one side of the instrument. | 07-16-2009 |
20100100058 | Micro-Vitreoretinal Trocar Blade - Embodiments of a micro-vitreoretinal trocar blade may have a top surface and a bottom surface that converge to form cutting edges. Each of the top surface and bottom surface have a large rounded apex to maximize the area of the blade. Each surface also has concave regions that may form the cutting edges. Advancing the MVR trocar blade into tissue causes the tissue to contact the apexes of the top and bottom surfaces. The apexes draw the tissue into contact with the cutting edges. The cutting edges incise the tissue such that the incision is sized to accommodate a trocar cannula. The geometry of the top surface and bottom surface ensure that the features of the blade do not protrude radially outside of the diametral envelope of the shaft. | 04-22-2010 |
20120157907 | VITRECTOMY PROBE WITH ADJUSTABLE CUTTER PORT SIZE - Vitrectomy probes and system related thereto are disclosed herein. The disclosure describes various example vitrectomy probes having an adjustable cutting port size. Various example features are described for adjusting the size of the cutting port. Further, the disclosure provides examples for adjusting the size of the cutter port while the vitrectomy probe is in operation. | 06-21-2012 |
20120157908 | VITRECTOMY PROBE WITH ADJUSTABLE CUTTER PORT SIZE - Vitrectomy probes and system related thereto are disclosed herein. The disclosure describes various example vitrectomy probes having an adjustable cutting port size. Various example features are described for adjusting the size of the cutting port. Further, the disclosure provides examples for adjusting the size of the cutter port while the vitrectomy probe is in operation. | 06-21-2012 |
20120165724 | HYDRAULIC VITRECTOMY PROBE - Hydraulic vitrectomy probes and methods and systems associated therewith are discussed. Example hydraulic vitrectomy probes may include a pressure multiplier that is operable to output a hydraulic pressure at a multiple of a received pneumatic pressure. Because of the incompressible nature of liquid, hydraulic vitrectomy probes are, among other things, more responsive, may be operated at higher cutting rates, provide improved patient safety, and have a form factor (e.g., size and/or shape) that may be more easily maneuvered by a surgeon. | 06-28-2012 |
20120165734 | DEVICE FOR AT LEAST ONE OF INJECTION OR ASPIRATION - 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. | 06-28-2012 |
20120221033 | SURGICAL PROBE WITH INCREASED FLUID FLOW - A surgical probe, e.g. a vitrectomy probe, and methods of making the same are disclosed. An exemplary surgical probe may include a tubular body and a cutting tool that is received within the body. The tubular body may define a cutting aperture that is adjacent a first end of the body and a fluid passage that extends through the body from the cutting aperture to a second end of the body. The cutting tool may be received within the body and disposed within the fluid passage. The cutting tool is generally configured to allow fluid flow through the cutting tool. The cutting tool may include a body portion and a blade portion that is configured to cut material entering the cutting aperture. The body portion may extend only partially about an inner circumference of the tubular body. | 08-30-2012 |
