AI Technical Summary
Existing PKP guides are not accurately positioned on the patient's skin surface, are complicated to operate, and lack spinous process positioning holes, resulting in a high puncture error rate.
A percutaneous PKP guide plate was designed, which includes a first spinous process aperture, a second spinous process aperture, and a guide channel. Combining radiopaque markers and 3D printing technology, the guide plate is designed to ensure precise alignment with the patient's vertebral body. The puncture position and angle are verified through multiple tilting guide channels.
This method enables precise vertebral body localization and puncture, shortens the surgical cycle, reduces patient risk, and improves the ease and safety of surgical procedures.

Abstract
Claims
1. A percutaneous PKP guide, characterized in that: The plate (1) includes a plate body (1), the middle region of which is provided with a first spinous process outline hole (11) adapted to the target vertebral body to be punctured, one end of the first spinous process outline hole (11) is provided with a second spinous process outline hole (12) adapted to an adjacent vertebral body below the target vertebral body to be punctured, and one or both sides of the first spinous process outline hole (11) are provided with a guide channel (13) for puncturing the superior articular process of the target vertebral body to be punctured, and the guide channel (13) is provided on one side of the plate body (1).
2. The percutaneous PKP guide according to claim 1, characterized in that: Each side has multiple guide channels (13), which are inclined relative to the plate (1), and the inclination angles of the multiple guide channels (13) are different.
3. A percutaneous PKP guide according to claim 2, wherein: Each side of the guide channel (13) is provided with three.
4. The percutaneous PKP guide according to claim 1, wherein: The plate (1) is a 3D printed plate.
5. The percutaneous PKP guide according to claim 1, wherein: The plate (1) has a radiopaque marker (14) on its surface surrounding the second spinous process outline hole (12), which corresponds to a vertebra below the target puncture vertebra.
6. A percutaneous PKP guide according to claim 5, wherein: The developing marker (14) is a marker pattern with a shape consistent with the cone, which is set on one side of the plate (1).
7. A percutaneous PKP guide according to claim 6, characterized in that: The developing marker (14) is integrally formed with the plate (1).
8. The percutaneous PKP guide according to claim 5, wherein: The imaging marker (14) is an imaging line that matches the outer contour of the vertebra adjacent to the target puncture vertebra.
9. The percutaneous PKP guide according to claim 1, wherein: One end of the plate (1) is recessed to the other side with a lumbar curve indentation (15) that matches the physiological curve of the patient's lumbar curve.
10. A percutaneous PKP guide according to any one of claims 1 to 9, characterized in that: The plate (1) has multiple air vents evenly distributed.
