20100168762 | Ophthalmic surgery support device - An ophthalmic surgery support device assisting an operator in the operation of a surgical instrument in order to position to a fine location in an eye the tip end of the surgical instrument to be inserted into the eye through a wound opening opened in the eyeball of a patient, comprising a moving mechanism for holding the surgical instrument so as to be movable in the longitudinal direction of the surgical instrument to be inserted into the eye or in the Z-axis direction, a tilting mechanism for holding the moving mechanism so that the surgical instrument can be tilted in an arbitrary direction about a specified point that is to be positioned to the wound opening and positioned on the Z-axis, and a tilt fixing mechanism for fixing the tilt of the surgical instrument by the tilting mechanism, wherein the tilting mechanism has a rough-motion tilting mechanism, a fine-motion tilting mechanism finer in tilting range than the rough-motion tilting mechanism, a tilt switching mechanism for switching the tilt of the surgical instrument by the rough-motion tilting mechanism to that by the fine-motion tilting mechanism, and a resistance imparting means for imparting resistance for damping the tilting operation of the surgical instrument by the fine-motion tilting mechanism than that by the rough-motion tilting mechanism. | 2010-07-01 |
20100168763 | CONFIGURATION MARKER DESIGN AND DETECTION FOR INSTRUMENT TRACKING - The present disclosure relates to systems, methods, and tools for tool tracking using image-derived data from one or more tool located reference features. A method includes: directing illuminating light from a light source onto a robotic surgical tool within a patient body, wherein the tool includes a plurality of primitive features having known positions on the tool, and wherein each feature includes a spherical reflective surface; capturing stereo images of the plurality of primitive features when the tool is within the patient body, wherein the stereo images are captured by an image capture device adjacent the illumination source so that the illumination light reflected from the imaged primitive features toward the image capture device substantially aligns with spherical centers of the surfaces of the imaged primitive features, and determining a position for the tool by processing the stereo images so as to locate the spherical centers of the imaged primitive features by using the reflected light. | 2010-07-01 |
20100168764 | SYSTEM AND METHOD FOR DETERMINING DISTANCE WITH PRECISION IN THE PRESCENCE OF MULTIPATH INTERFERENCE - Various aspects of the present invention are shown and described, each of which has stand alone utility in a navigated medical environment. A receiver position calibration system and method facilitates calibration of a reference frame prior to each navigated procedure. A concept and application of confidence weights is introduced. Confidence weights can be applied to distance calculations to mitigate the effects of interference and increase the tolerance of the navigated medical system. Multi-path interference is minimized through the transmission of a signal having a pattern of unique frequencies and filtering of the distance calculations for each frequency to identify the ‘best’ distance in the presence of multi-path interference. A position determination method and system that transmits a signal having multiple frequency components permits positions to be identified with high resolution over a large area. | 2010-07-01 |
20100168765 | SURGICAL MECHANISM CONTROL SYSTEM - A surgical mechanism control system comprising: a beam emitter unit configured to emit only a single beam and adapted to be attached to a surgeon; a first pair of discrete beam detectors each adapted to detect an incident beam emitted by the beam emitter unit and output a corresponding control signal when in incident beam is detected; and a control unit configured to receive one or more control signals output by the beam detectors and control a surgical mechanism in accordance with the one or more control signals. | 2010-07-01 |
