Abstract
First sensing means senses the three-dimensional position of a microscope, with an operating site as the origin. Second sensing means senses the three-dimensional position of a surgical instrument with respect to the microscope. On the basis of the sensing results of the first sensing means and second sensing means, computing means calculates the three-dimensional position of the surgical instrument, with the operating site as the origin.
Claims72
A surgical microscope comprising:
- a medical instrument;
- a first detector that is placed in a desired position, and that is configured to detect positional information of a microscope in three dimensions;
- a second detector that is mounted on the microscope at a predetermined position, and that is configured to detect positional information of the medical instrument with respect to the microscope in three dimensions;
- and
- a processor configured to calculate a three-dimensional position of the medical instrument with respect to the first detector based on the positional information of the microscope detected by the first detector and the positional information of the medical instrument detected by the second detector.
