  • Patent number: 10786323
    Abstract: Various embodiments provide a handheld surgical instrument including a laser source configured to emit a laser beam for generating a laser marker on a surface, an inertial measurement unit configured to detect a motion of the handheld surgical instrument and generate a first signal including information on the motion of the handheld surgical instrument detected by the inertial measurement unit, and a movable platform for holding a controlled tool tip. The handheld surgical instrument additionally includes an actuator mechanically coupled to the movable platform, and a processing circuit configured to control the actuator to move the movable platform based on the first signal generated by the inertial measurement unit and a second signal generated by a vision unit based on a movement of the laser marker, so that the movement of the movable platform at least partially compensates a tremulous motion of the handheld surgical instrument.

  • Publication number: 20190225923
    Abstract: An apparatus for embryo biopsy is provided. The apparatus includes an enclosure and an incubation unit which is disposed in the enclosure and which is configured to incubate an embryo. The apparatus further includes an embryo manipulator setup which is disposed in the enclosure and which is configured to rotate the embryo. The apparatus further includes an embryo image capturing mechanism which is disposed in the enclosure and which is configured to capture an image of the embryo in the incubation unit so as to monitor the morphology of the embryo to determine a development stage of the embryo in the incubation unit. The embryo manipulator setup is further configured to be activated to rotate the embryo to a predetermined orientation based on a determination that the embryo is at a predetermined development stage.
