[0022] Embodiment 1:

[0023] See also Figure 1 - Figure 3 The utility model of the CT-guided chest puncture positioning auxiliary device comprises: a plurality of metal positioning blocks 1 for positioning, wherein the plurality of metal positioning blocks 1 are evenly installed on the outside of the chest cavity;

[0024] The mounting unit comprises two mounting plates 2, a plurality of mounting components 3 are transversely mounted between the two mounting plates 2, a plurality of metal positioning blocks 1 are arranged on the mounting components 3, and the spacing between the metal positioning blocks 1 relative to the orthographic projections of the CT detection bed is equal.

[0025] The mounting component 3 is a non-metallic hard bracket, and a plurality of metal positioning blocks 1 are embedded in the hard bracket. The non-metallic hard bracket enables the metal positioning blocks 1 to be stably located outside the chest cavity without affecting imaging.

[0026] It also includes a connecting component 4 installed on the mounting plate 2, the connecting component 4 includes a negative pressure tube 41 embedded on the mounting plate 2, a negative pressure suction cup 43 is provided at the bottom of the negative pressure tube 41, and a deflation valve 44 is provided on the negative pressure tube 41. A piston rod 42 is provided inside the negative pressure tube 41, the top of the piston rod 42 movably penetrates the negative pressure tube 41, and the piston rod 42 is threadedly connected to the top of the negative pressure tube 41. When the connecting component 4 is in use, the negative pressure suction cup 43 is buckled on the CT inspection bed, and then the piston rod 42 is rotated to move the piston rod 42 upward inside the negative pressure tube 41, thereby generating negative pressure to adsorb and fix the mounting plate 2 on the CT inspection bed.

[0027] Both ends of the rigid bracket are connected to the corresponding mounting plates 2 through hinges or bolts.

[0028] In this embodiment, if both ends of the rigid bracket are connected to the mounting plate 2 by bolts, the person needs to lie on the CT examination bed first, and then the mounting plate 2 and the mounting component 3 carrying the metal positioning block 1 are located outside the chest cavity through the connecting component 4, and then the CT examination is performed, and the coordinates of the lesion site are provided by the different imaging of the metal on the CT film;

[0029] If both ends or one end of the hard bracket is connected to the mounting plate 2 by a hinge, the connecting component 4 on one side of the mounting plate 2 can be installed on the CT detection bed first, and then the mounting plate 2 on the other side can be fixed after the person lies on the CT detection bed, that is, the device can be installed on the CT detection bed in advance.
