Abstract

The invention discloses a surgical navigation system, comprising: a magnetic field generator for generating an electromagnetic field; the first electromagnetic positioning assembly is fixed on a target object, and the first electromagnetic positioning assembly is used for generating a first induction current under an electromagnetic field; the second electromagnetic positioning assembly is fixed on the surgical instrument, and the second electromagnetic positioning assembly is used for generating a second induction current under the electromagnetic field; the controller is used for acquiring the first induction current and the second induction current, and determining a first pose of the target object and a second pose of the surgical instrument according to the first induction current and the second induction current respectively; and the controller is also used for determining a conversion relation between an image coordinate system of the three-dimensional medical image and a magnetic field coordinate system of the electromagnetic field according to the three-dimensional medical image of the target object, a first two-dimensional medical image containing the target object and the surgical instrument, the first pose and the second pose, and guiding the surgical instrument to operate to realize navigation.

Description

technical field [0001] The invention relates to the technical field of surgical navigation, in particular to a surgical navigation system. Background technique [0002] In recent years, surgery has made great progress, but for lesions with complex anatomical structures, the difficulty and risk of surgery are still high. Taking spinal surgery as an example, the anatomical structure of the spine is complex and adjacent to important blood vessels and nerves. Accurate placement of pedicle screws in spinal surgery is a prerequisite for good orthopedic surgery, and the process of screw placement is likely to damage the large blood vessels and nerves around the vertebral body. Nerves, so precise nail implantation has become the key and technical difficulty of the surgery. [0003] Surgical guidance systems can help medical personnel locate the lesion, reduce the difficulty and risk of surgery, and are increasingly used in surgical operations. However, the accuracy of the traditio...
