Abstract: PURPOSE: To carry out pricise positioning of surgical tools when a surgical treatment is given to a patient by instant and consecutive feed back of information about the tool in the three-dimensional directions to a surgeon through mounting a link system with a precise measuring instrument driven by a computer on the surgical tool. CONSTITUTION: A standard block 9 and an electric goniometer 7 are connected to an oscillating balancing arm 11 so as to move the electric goniometer 7 and the standard block 9 to various positions along the body of a patient 3. The other end of the balancing arm 11 is connected to an upright pole 13 of a movable upright stand 15. The upright pole 13 also supports a monitor and, if possible, a monitor supporting arm 17 movable carrying a color monitor 19. Therefore, the usage of the link system allows a physical relationship between a point of a patient's foot, e.g. and the standard block 9 to be formed invariably. Consequently, any motion transmitted to the patient's foot is transmitted to the standard block as it is.

Abstract: A method for measuring parameters relating to the stability of joints in a patient's body includes the steps of securing a reference portion of the joint (that portion of the joint closest to the body) to a fixed location. A three dimensional digitization of the size, shape, position and coordinate system of the two portions is performed. A soft tissue compensation procedure is performed by applying forces to the reference portion of the joint to thereby determine the amount of reference portion motion, in the soft tissue surrounding the reference portion, due to these forces. A variety of forces are applied to the relative portion of a joint, which is movable relative to the reference portion thereof, and the total motion of the reference and relative portions associated with the forces are measured. By subtracting the motion determined in the soft tissue compensation from motion as determined by applying a variety of forces, the motion of only the relative portion relative to the reference portion is determined.

Abstract: 3-DIMENSIONAL DIGITIZER FOR SKELETAL ANALYSIS A method of performing 3-dimensional skeletal analysis on a patient using an apparatus which includes a digitizer, the digitizer being adapted to accept either a scanning digitizer tip or a point digitizer tip, includes the steps of placing the patient in a variety of positions relevant to musculoskeletal problems and performing a series of rolling scans, with the scanning digitizer tip and single point landmark digitizations of musculoskeletal landmarks, with the point digitizer tip to obtain 3-dimensional skeletal data. The data is analyzed in order to provide clinically relevant 3-dimensional information relating to musculoskeletal quantities and imbalances. An apparatus for carrying out the method includes an upright column support and a retractable column support movable along the support column for supporting the patient. A digitizer measures the position of a point, or a group of points, on the patient's body in 3-dimensional space. The digitizer includes a plurality of rotatable transducers and a plurality of link members linking the rotatable transducers. The digitizer is connected at one end to the support column and has a free end. The free end of the digitizer is adapted to accept a digitizer tip. The apparatus also includes a computer and the output of the digitizer is connected to the computer whereby to provide data to the computer for computing the position of the point or group of points on the patient's body in 3-dimensional space.

Abstract: To aid a medical practitioner in positioning a surgical instrument or implant when performing surgery on or examining portions of a patient, patient data is developed which identifies the position and orientation of the portion to which surgical procedures or examinations are to be applied. The position and orientation of the instrument or implant is sensed and instrument data is developed from this sensing. The patient data is converted to objective signals to be displayed on a video display, and the instrument data is converted to instrument signals for presenting the position and orientation of the instrument or implant on the same display. Thus, by watching the display, the medical practitioner is aided in manipulating the instrument or implant relative to the portion.
