Abstract:
1. A surgery support device comprising: a profile measurement means for optically measuring a surface of a subject and obtaining surface profile information representing the three-dimensional coordinate position of each location across an entirety of the subject surface; input means for inputting a plurality of high resolution tomographic images of the subject captured prior to surgery; correspondence processing means for acquiring the surface profile information obtained by the profile measurement means prior to surgery and corresponding each location on the subject surface with a surface position in the high resolution tomographic images, based on the acquired surface profile information and based on the plurality of high resolution tomographic images input by the input means; acquisition means, provided with correction means, for acquiring surface profile information during surgery with the profile measurement means and correcting the correspondence relationship between each location of the subject surface and the surface position in the high resolution tomographic images with the obtained surface profile information, and acquiring as surface profile information three-dimensional coordinate positions of the surface of the exposed portion of a surgical instrument having a specific profile used for surgery and three-dimensional coordinate positions of each location on the surface of the subject by measuring the surface of the subject and the surface of the exposed portion of the surgical instrument using the profile measurement means during surgery, deriving the position of the exposed portion of the surgical instrument based on the acquired surface profile information and acquiring instrument position information representing the three-dimensional coordinate position of an unexposed portion including the distal end portion of the surgical instrument, based on the derived position of the exposed portion; combining means for combining, based on the instrument position information acquired by the acquisition means, a surgical instrument image with the high resolution tomographic images such that the surgical instrument image showing the unexposed portion of the surgical instrument is aligned with each position of the unexposed portion including the distal end portion of the surgical instrument; and a display controller displaying the combined high resolution tomographic images combined by the combining means on a display.
