20150335473 | OPHTHALMIC SURGICAL FLUID HANDLING CASSETTE - An ophthalmic system ( | 11-26-2015 |
20140194870 | DUAL IRRIGATING BIPOLAR FORCEPS - Bipolar electrosurgical forceps are provided with dual irrigating tubes that deliver irrigating liquid to the opposed surfaces of the tips of the forceps to prevent the sticking of body tissue to the tips. To reduce the manufacturing costs of the forceps and enable the forceps to be single use, disposable forceps, each tube of the dual irrigating tools is a plastic tube adhered along one of the opposing surfaces of the pair of forceps arms. Each tube also has a flat nozzle at the distal end of the tube that disburses irrigating liquid across the opposed surfaces of the forceps arm distal and tips. | 07-10-2014 |
20140180013 | TROCAR SYSTEM HAVING A DRIVE - Systems and methods for using a trocar system are disclosed. The system generally includes a handle having a first end a second end, a trocar disposed adjacent the first end of the handle, a plurality of cannulas disposed on the trocar simultaneously, and a drive system. The drive system is disposed for forward movement of the cannulas in a longitudinal direction away from the first end of the handle. | 06-26-2014 |
20140121690 | AXIALLY RECIPROCATING MICROSURGICAL INSTRUMENT WITH RADIALLY COMPRESSED ACTUATOR HANDLE - A microsurgical instrument has a pair of operative surgical surfaces that are moved relative to each other in shearing or grasping procedures performed by the instrument. The instrument has a handle containing an elongate center rod with a ring mounted for reciprocating movement on the rod. A tube is secured to the ring and a shaft extends through the tube and is secured to the rod. The handle also includes a plurality of resilient arms that extend along the length of the rod and engage against a sliding surface of the ring on the rod. The plurality of actuator arms are alternatively manually compressed radially inwardly by the surgeon's hand and released by the surgeon's hand to allow the arms to flex radially inwardly and outwardly. The inward and outward movement of the plurality of arms reciprocates the ring on the handle rod and causes the tube and shaft to move axially relative to each other. | 05-01-2014 |
20130261610 | SURGICAL INSTRUMENT HANDLE WITH CAM-ACTUATING SYSTEM - A surgical instrument handle having a cam-actuated system is disclosed. The surgical instrument handle includes a rotating member that defines a cam-actuating surface operatively engaged with a locking member, which is fixedly engaged to a reciprocating member for moving the reciprocating member between a retracted and extended positions. The cam-actuating surface of the rotating member is configured to permit the locking member to slide along the cam-actuating surface such that the tangential angle along the point of contact between the locking member and the cam-actuating surface is maintained at a predetermined angle. | 10-03-2013 |
20130102967 | Magnetic Trocar System - Systems and methods for using a trocar system are disclosed. The system generally comprises a trocar, a magnet, and a magnetizable cannula. The trocar has a first end and a second end. The magnetizable cannula has a central opening sized to receive the trocar. The magnet is positioned adjacent the second end of the trocar and its magnetic field releasably secures the magnetizable cannula in a position adjacent the second end of the trocar. | 04-25-2013 |
20130102966 | Trocar System - Systems and methods for using a trocar system are disclosed. The system generally includes a handle having a first end a second end, a trocar disposed adjacent the first end of the handle, cannulas disposed on the trocar, and a drive system. The drive system is disposed for forward movement of the cannulas in a longitudinal direction away from the second end of the handle. | 04-25-2013 |
20130053846 | NON-STICK BIPOLAR FORCEPS - Disposable, bipolar electrosurgical forceps are designed to prevent the sticking of body tissue to the tips of the forceps and include a pair of electrode arms having lengths with opposite proximal and distal ends, with thin layers of biocompatible metal on the forceps arm distal ends and bipolar electrical conductors permanently secured to the forceps arm proximal ends. | 02-28-2013 |
20120310146 | SYSTEMS AND METHODS FOR VITRECTOMY - A system for conducting a vitrectomy includes: a gas source; a vitrector including a cutting mechanism that opens and closes according to a pressure at the vitrector; and a pulse-generating system receiving gas from the gas source and generating pulses at the vitrector. The pulses cause the pressure at the vitrector to vary according to a cycle, and the varying pressure at the vitrector causes the cutting mechanism of the vitrector to open and close. At a first time in the cycle, the pulse-generating system, raises the pressure at the vitrector to a maximum pressure. At a second time in the cycle, the pulse-generating system reduces the pressure at the vitrector to a minimum pressure that is greater than ambient, the pressure at the vitrector being maintained at least at the minimum pressure. The difference between the maximum pressure and minimum pressure is minimized to reduce gas consumption. | 12-06-2012 |
20120302943 | Systems and Methods For Deoxygenating Opthamalic Fluid - Systems and methods for deoxygenating ophthalmic fluid are disclosed. The systems include an infusion system having a valve having an inlet in fluid communication with a source of gas, a first outlet in fluid communication with a container of ophthalmic fluid, and a second outlet in fluid communication with an infusion line of the system. The valve directs gas into the fluid disposed in the container to deoxygenate the fluid, and the deoxygenated fluid is then injected into the eye. | 11-29-2012 |
20080287938 | Illuminated Directional Laser Probe - An ophthalmic surgery illuminated directional laser probe has a handle and a rigid tubular tip projecting from the handle, and has an illumination optic fiber and a laser optic fiber that extend through the handle and the tip. A mechanism on the handle is operable to extend distal ends of the illumination optic fiber and the laser optic fiber from the distal end of the instrument tip, and to retract the distal ends of the illumination optic fiber and the laser optic fiber back into the interior of the tip. At least one of the distal ends of the illumination optic fiber and the laser optic fiber is held in a curved configuration. The distal ends of the illumination optic fiber and the laser optic fiber are secured to each other, whereby both the illumination optic fiber and the laser optic fiber curve into a bent configuration as the distal ends of the illumination optic fiber and the laser optic fiber are extended from the distal end of the instrument tip. | 11-20-2008 |
20080275435 | Illuminated Laser Probe with Multiplied Area of Illumination - A microsurgical laser probe has a handle and a tubular tip that projects from the handle, and three optic fibers that extend through the handle and the tip. One of the optic fibers is a laser optic fiber that is adapted to be connected to a source of laser light at one end of the laser optic fiber, and to transmit the laser light from the opposite end of the laser optic fiber at the distal end of the instrument tip. The other two optic fibers are illumination light optic fibers. Each illumination light optic fiber has one end that is adapted to be connected to a illumination light source, and an opposite end that projects the illumination light from the distal end of the instrument tip. By providing two laser light optic fibers in the instrument, the amount of illumination directed to the surgical site being accessed by the laser optic fiber is effectively doubled. | 11-06-2008 |
20080207992 | Microsurgical Illuminator with Adjustable Illumination - An adjustable ophthalmic surgery chandelier illuminator has a glass optic fiber with a conical exterior surface at its distal end that disburses illumination in the interior of the eye. The glass fiber is contained in a retractable needle that has a long, sharp beveled surface that facilitates insertion of the needle and the optic fiber into the eye, and then is retracted relative to the fiber distal end to adjust the field of illumination inside the eye. | 08-28-2008 |
