  • Publication number: 20150190280
    Abstract: An apparatus for irradiating a specimen: that includes an optical transmitter for transmitting light from a laser source; an optical probe configured to receive the light from the optical transmitter and to apply the light upon emission from an optical exit to the specimen; a position detector adapted to detect a position of the optical probe in a longitudinal direction and to output a signal indicative of the position or of a change in the position relative to a surface forward of the optical probe; a drive coupled to the optical probe and adapted to controllably adjust a position of the optical probe in the longitudinal direction; and a feedback controller adapted to receive the signal from the position detector and to control the drive to control the position to keep the optical probe at substantially a constant position relative to the surface forward of the optical probe.

  • Patent number: 6544249
    Abstract: The present invention provides a microfistula tube including a soluble duct, defining a drainage canal having an inner surface, the duct being biocompatible, wherein the microfistula tube is coated with and/or incorporates biological for forming a basement membrane, or an intracellular matrix and a basement membrane. The biological cells may coat the inner surface of the drainage canal, and the microfistula tube may be made of a mouldable material or an absorbable material. The invention also provides an implantation system for the microfistula tube including a microfistula tube and a surgical instrument including an outer tube for penetrating body tissue, an inner tube, and an innermost rod, wherein the outer tube, the inner tube and the innermost rod are coaxial, the outer tube is adapted to receive said microfistula tube, whereby the inner tube may be used to push the microfistula tube into position and the innermost rod provides mechanical support during implantation of the microfistula tube.

  • Patent number: 6264665
    Abstract: A system (10) for ocular ultramicrosurgery a ring (12) for immobilising eye (14) of a patient. The incision point (P) on the eye (14) for surgical tools is marked by a marker (16) that is generated by intersecting tire beams of lasers (104 and 106). The intersection point of the laser beams is fixed in space. In order to move the patient's eye (14) so that point (P) coincides with that fixed point in space, the patient's head (52) is fixed to a head positioner (24). The head positioner is operated by a surgeon (26) through joystick (34) and computer (32) to ensure registration of point (P) and the point designated by the intersecting laser beams. All surgical tools used in the system (10) are supported, positioned and operated or worked by a tool support and positioning system (18). The system (18) comprises a stereotactic manipulator (20) and a tool translation table (22) which is supported on the manipulator (20).
