  • Patent number: 11666458
    Abstract: Proposed are an apparatus and method for spinal surgery planning, the spinal surgery planning method including: acquiring a two-dimensional (2D) spinal image of a patient through a medical imaging apparatus; calculating a registration relationship between coordinates in an image space and coordinates in a surgical space by registering the image space for the spinal image and the surgical space where spinal surgery is performed on the patient; generating a virtual three-dimensional (3D) figure in the surgical space; projecting the 3D figure onto the spinal image based on the registration relationship; adjusting the 3D figure so that the 3D figure can correspond to a predetermined landmark on the spinal image; and setting an insertion position and insertion path of a spinal prosthesis based on the spinal image and the 3D figure.

  • Patent number: 11666390
    Abstract: A system for planning pedicle screw fixation includes: a C-arm configured to capture a spinal image of a patient; an insertion path provider configured to provide an entry point and an insertion endpoint of a pedicle screw on a C-arm image; a registrator configured to calculate spatial coordinates of the entry point and the insertion endpoint based on a reference coordinate system; a guider configured to determine an insertion position of the pedicle screw based on the spatial coordinates of the entry point and the insertion endpoint, and guide a probe to be inserted toward the entry point according to the insertion positions; and a screw determiner configured to determine a length condition of the pedicle screw by obtaining coordinates of a start point at which the probe is inserted and becomes in contact with a bone.
