  • Publication number: 20190083129
    Abstract: Surgical devices and methods of using the surgical devices are disclosed. The surgical devices generally include a trocar, a cannula releasably mounted on the trocar, and a propulsion system operatively connected to the trocar. The cannula includes a hub, and has a central opening through which the trocar extends. The propulsion system is operable to drive the trocar axially in a forward direction away from a proximal end of the surgical device.

  • Patent number: 10219941
    Abstract: 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.

  • Patent number: 8512340
    Abstract: A torsional dissection tip and method of use comprising a longitudinal-torsional resonator having a cutting surface at a distal end with cutting teeth of a pitch optimized to the torsional or longitudinal displacement of the distal tip. The present art apparatus and method of use utilizes uniquely designed cutting surface geometries with the aforesaid pitch attributes for surgical applications. Utilization of the present art torsional dissection tip allows a surgeon to easily remove hard tissues such as bone without moving the present art instrument to any site except that which is to be dissected.

  • Publication number: 20120302943
    Abstract: 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.

  • Publication number: 20080051770
    Abstract: A multiple target ophthalmic surgery instrument is comprised of a single primary optic fiber that transmits laser light to the instrument, and a plurality of additional optic fibers that receive the laser light from the primary optic fiber and project the laser light as a plurality of beams from the plurality of additional optic fibers. In this manner, the instrument splits the single laser light beam received from a single laser light source into the multiple of laser beams and targets the multiple laser beams at multiple spots of a surgical site in the eye.

  • Patent number: 7189226
    Abstract: A coaxial illuminated laser endoscopic probe and active numerical aperture control apparatus and method of use, succinctly known as an illumination and laser source, capable of selectively providing illumination light and laser treatment light through a single optical fiber. The apparatus and method is especially useful during ophthalmic surgery. The present art is capable of providing the aforesaid through an optical fiber of such small size that heretofore said fiber was only useable for laser treatment light only. The present art also, with its unique optical system, allows for two illumination light outputs from a single illumination source. The apparatus utilizes a phototoxicity risk card to calibrate the system to prior art or safe illumination levels since the unique optical system provides illumination light of greater intensity than the prior art.
