  • Patent number: 9510783
    Abstract: A system, and a method for its use, provides for placement of a fluid delivery needle into the tail of a laboratory animal. The system includes an animal receiving portion, structure configured to receive, position and restrain a tail of the animal placed in the animal receiving portion and a hollow needle attached to a fluid transfer device. Positioning structure is provided to align the needle and fluid transfer chamber with the restrained tail for proper automated insertion of the needle into a blood vessel within the tail. A lateral actuator operatively connected to the fluid transfer device moves the hollow needle in a forward direction so that it is inserted into the blood vessel of the properly aligned tail. The system can include a computer programmed to automatically perform all of the functions and operate all the components of the system.

  • Publication number: 20160127702
    Abstract: The present disclosure provides augmented reality methods and systems where two or more component optical images are optically overlaid via one or more beam splitters to form composite optical images. In some embodiments a second component optical image is an electronic optical image (an image from an electronically controlled emission source) while the first component optical image is one of a physical optical image (an image of a physical object from which diffuse reflection occurs), an electronic optical image, an emission optical image (an image from a non-electronic source that emits radiation), or a hybrid optical image (composed of at least two of a physical optical image, and electronic optical image, or an emission optical image). In some embodiments the first and second component optical images are used to provide feedback concerning the quality of the overlaying and appropriate correction factors to improve the overlay quality.

  • Patent number: 9283043
    Abstract: A system for microsurgery includes a first assembly and a second assembly, each including: (1) a planar remote center of motion (RCM) device configured to constrain motion of a surgical instrument attached to the planar RCM device such that an axis of the surgical instrument passes through the RCM while remaining in a planar region defined based on a rotational orientation of the planar RCM device; and (2) a rotational device attached to the planar RCM device and configured such that an axis of rotation of the rotational device passes through the remote center of motion. The rotational orientation of the planar RCM device is defined about the axis of rotation. The first assembly and the second assembly are configured to be positioned such that a distance between the remote centers of motion of the first assembly and the second assembly is no greater than two centimeters.

  • Publication number: 20150141801
    Abstract: Specific embodiments of the invention are directed to improved surgical procedures involving the use of processed non-visual three-dimensional data (i.e. diagnostic scan data) to provide a surgeon with additional guidance (i.e. more than that generally obtained from visual observation of the working area) concerning the distance separating a working end of a surgical instrument and the posterior portion of a target tissue. Separation information may be used to aid the surgeon in minimizing the risk of unintended penetration of adjacent tissue with the working end of the instrument. Some embodiments provide for the visual and/or auditory conveyance of distance information to the surgeon. Additional embodiments provide for overlaying visual representations of selected three-dimensional structure information (e.g. depths of troughs cut into the lens) with the real surface feature images viewed by the surgeon.

  • Patent number: 8945140
    Abstract: The present disclosure is directed to improved phacoemulsification procedures involving the use of processed non-visual three-dimensional data (i.e. diagnostic scan data) to provide a surgeon with additional guidance concerning the distance separating a working end of a phacoemulsification instrument and the posterior capsule of the eye during a surgical procedure involving the removal of the crystalline lens of an eye. Such information is implemented to aid the surgeon in cutting or scoring the lens to a desired depth while minimizing the risk of penetrating the posterior portion of the capsule with the working end of the instrument. Some embodiments provide for the visual and/or auditory conveyance of distance information to the surgeon. Additional embodiments can provide for overlaying visual representations of selected structure information with the images provided to the surgeon.
