Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0038] The positioning accuracy detection device of the surgical navigation system of the present invention has a structure such as figure 1 As shown, its main body is a sealable cylinder consisting of a base 1, a detachable upper cover 2, and a detachable headform 3.

[0039] like figure 2 As shown, the base 1 is composed of a base 4 , an outer cover 7 , a plexiglass rod 5 and a plexiglass rod 6 . The base 4 is located on the bottom surface of the base 1, and it is made of opaque nylon material. Dig 32 holes with a certain diameter on the base 4 for assembling 32 plexiglass rods as targets; A threaded hole with the same diameter as the connecting bolt 11, when the upper cover 2 is assembled, screwed into the threaded hole with the connecting bolt 11, tightened, and the upper cover 2 is fixed. Insert 32 plexiglass rods 5 with a length rang...

Abstract

The invention discloses a device for detecting positioning accuracy of a surgical operation navigation system. The main body of the device is a sealable cylinder, comprising a base, a detachable upper lid and a detachable head die. The base comprises a pedestal, an outer cover and a plurality of organic glass rods. The pedestal is provided on the bottom surface of the base and a plurality of organic glass rods of different lengths are provided on the pedestal. The outer cover which is provided on the side of the base is bonded on the pedestal, and a plurality of organic glass rods of the same length are provided on the cover. The detachable upper lid comprises a sealing lid, a connecting bolt and a water injection hole screw. The connecting bolt is provided in the center of the sealing lid for screwing the upper lid. The water injection hole screw which is used for injecting water is provided beside. The upper lid is contacted and is fixed with the base. The detachable head die is fixed on the pedestal of the base and inside the outer cover of the base. The invention further discloses a detecting method of the device. According to the invention, not only point registration accuracy but also surface registration accuracy can be detected, which promotes higher and more real detection accuracy.

Description

technical field [0001] The present invention relates to a surgical operation navigation system, in particular to a positioning accuracy detection device for a surgical operation navigation system, in particular to a positioning accuracy detection device for a surgical operation navigation system based on tomographic images. In addition, the present invention also relates to a detection method of the positioning precision detection device of the surgical navigation system. Background technique [0002] For a long time, although advanced imaging diagnostic equipment and technologies such as CT and MRI have been available, it is still difficult for surgeons to locate and find lesions during surgery. The extent of lesion resection mainly depends on the surgeon's subjective judgment and personal experience. Surgical navigation technology is derived from stereotactic neurosurgery, which combines medical imaging diagnosis technology, spatial positioning technology, three-dimensiona...
