  • Patent number: 7477927
    Abstract: A method and system for laser based instrument registration. The system includes an operating table coupled with a robot holding an instrument, and CT scanner. The CT scanner has first and second laser markers. The method includes moving the robot to align the instrument in a first position wherein a tip of the instrument is disposed within a first laser plane created by the first laser marker. Then, the robot moves the instrument to a second position wherein the entire instrument is disposed within the first laser plane. Coordinate data of the robot in the second position is obtained. Image data of a first slice is obtained from the CT scanner. The registration data is calculated based on the coordinate data and the image data.

  • Patent number: 7289883
    Abstract: A method for remotely monitoring a patient. The method includes generating and transmitting input commands to the robot from a remote station. The remote station may include a personal computer that is operated by a doctor. The input commands can move the robot so that a video image and sounds of the patient can be captured by a robot camera and microphone, respectively, and transmitted back to the remote station. The robot may also have a monitor and a speaker to allow for two-way videoconferencing between the patient and a doctor at the remote station. The robot can move from room to room so that a doctor can make “patient rounds” within a medical facility. The system thus allows a doctor visit patients from a remote location, thereby improving the frequency of visits and the quality of medical care.

  • Publication number: 20070034047
    Abstract: A motor suitable for use in a medical imaging environment has (a) a cylindrical outer gear having a bore with a centerline and an internal surface with circumferentially distributed and radially directed teeth, (b) a means for mounting this outer gear such that it is constrained to move in rotational motion about its centerline, (c) a cylindrical planetary gear having a bore and an external surface having circumferentially distributed and radially directed teeth, (d) a means located within the planetary gear bore for applying a fluid pressure driven force to cause it to move in translational-circular motion about the outer gear's centerline, and (e) wherein the teeth of these gears are configured so as to cooperate such that the translational-circular motion of the planetary gear causes the rotational movement of the outer gear.

  • Publication number: 20070034046
    Abstract: A stepper motor suitable for use in a medical imaging environment has (a) a cylindrical central gear having two ends with a center line extending between these ends, and an external surface with circumferentially distributed and radially directed teeth, (b) a means for mounting the central gear such that it is constrained to move in rotational motion about its centerline, (c) a cylindrical hoop gear having a bore with an internal surface having circumferentially distributed and radially directed teeth, (d) a means for mounting the hoop gear such that it is constrained to move in translational-circular motion about the central gear's centerline, wherein this central gear is further configured to fit within the hoop gear's bore in such a manner that a plurality of the central gear and hoop gear teeth intermesh, and wherein these hoop gear teeth are further configured so as to cooperate with the central gear teeth so that the planetary movement of the hoop gear teeth causes the central gear to rotate, and (e) a

  • Patent number: 7051610
    Abstract: A ball-worm transmission is provided which replaces the sliding friction of the classic worm mechanism with the rolling friction of spherical balls. The ball-worm transmission assembly includes a worm which defines a recirculation path, and a gear coupled to the worm via a plurality of spherical balls. The gear includes a plurality of teeth each having a thickness in a central plane of the gear and a lesser thickness towards both sides of the gear, so that a gap is defined between the teeth is larger towards both sides of the gear than in the central plane of the gear.

  • Publication number: 20050214727
    Abstract: A training and/or evaluating device is provided particularly useful in performing laparoscopic procedures, radiological procedures, and precise surgeries that simulates the structure and dynamic motion of the corresponding anatomical structure on which the procedure takes place. The device includes an outer housing, which may be designed to mimic the body wall, in which one or more organs are located. Motion of the organ(s), as a result of respiration, pulmonary action, circulation, digestion and other factors present in a live body, is simulated in the device so as to provide accurate dynamic motion of the organs during a procedure.

  • Publication number: 20050124452
    Abstract: A motor suitable for use in a medical imaging environment has (a) a centrally located means for actuating a radial wave, (b) a deformable flexspline having an inner surface and a toothed outer surface, with the flexspline coaxially aligned with the central axis of the radial wave actuating means and oriented such that the flexspline inner surface is proximate the outer boundary surface of the actuation means, and with the flexspline toothed outer surface having a first specified number of teeth, and (c) a circular spline having a toothed inner surface, this spline having an outer boundary surface and being coaxially aligned with the central axis and oriented such that the spline toothed inner surface is proximate the flexspline's toothed outer surface, with the spline inner surface having a second specified number of teeth which is different than the first specified number of teeth in the flexspline, wherein the actuation means is operable so that the action of its radial wave causes at least one of the flexs
