板。Figure 1 is an explanatory diagram of stereotactic neurosurgery using CT, which is currently being performed. . The figure below shows the state in which the three-dimensional coordinates of the lesion position are transferred to the stereotactic neurosurgical device, and the surgical tool is attached to the transferred position. Figure 2 is a perspective view of the inventive splitter attached to a stereotactic neurosurgical device incorporating three-dimensional coordinates, and Figure 3 is a front view of the splitter similarly attached to the stereotactic neurosurgery device. Figure 4 is a side view of Figure 3, Figure 5 is a structural explanatory diagram of the splitter of the present invention,
FIG. 6 is a side view of FIG. 5, and FIG. 7 is a front view of an elevating support body to which the splitter is detachably attached. 1... Head ring, 2... Lesion image on tomogram, 3... Chart board, 41,4 degrees... Thin buried aluminum rod, 8... Cursor, 9... Y axis scale, 1

Claims

[Scope of utility model registration request]

A cleaving device attached to a CT stereotactic neurosurgery device incorporating a three-dimensional three-dimensional coordinate transfer mechanism, the cleaving device having a cleaving blade 15. , 15□ are opened and closed by a link mechanism 16, and at the maximum opening, the tip and the base of the blade are parallel to each other, and the shape of the blade is similar to the tip 18.
It has a gentle taper shape from the base part 19 toward the base part 19, and has a C-shaped flat cross-sectional shape, and the splitting blade and the link mechanism operation part are connected by the original eccentric arm 17. Features: Stereotactic neurosurgery retractor.
