Three-dimensional guide frame for CT (Computed Tomography) puncture

The invention relates to the technical field of medical auxiliary instruments, in particular to a CT puncture three-dimensional guide frame which comprises a base, one side of the base is connected with a mounting seat through a lifting mechanism, an arc-shaped guide support is arranged on one side of the mounting seat, mounting sleeves are fixedly connected to the two ends of the guide support, and puncture needle guide mechanisms are inserted into the mounting sleeves. A channel for a puncture needle to pass through is formed in the middle of the puncture needle guiding mechanism. According to the CT puncture three-dimensional guiding frame of the structure, the guiding support is rotationally connected with the mounting base through the connecting base, 360-degree rotation adjustment of the guiding support is facilitated, the guiding support is in meshed connection with the adjusting gear through the sawteeth, vertical rotation adjustment of the guiding support is facilitated, and the guiding support is co
