by providing a combined structure with a positioning rod, a sighting device, a puncture cone sleeve and a propelling sleeve, the combined structure not only realizes the function of puncture safety, but also has the sighting function, has better operation effect and is suitable for vertebral pedicle external centrum puncture operation;

in the process of puncturing by using the device, because the positioning rod is positioned in the vertebral pedicle and the abduction angle is 0 degree, the positioning rod can not enter the vertebral canal to hurt the nerve during puncturing;

after the positioning rod is fixed, the sighting device can be installed, so that the blindness in the subsequent puncture process is reduced, the surgical puncture risk is reduced, and the number of times of perspective is reduced;

when the device is used for implementation, the puncture target point is positioned at the upper back of one side of the vertebral body, the part has no important vascular nerve, the puncture is safe, the bone cement propelling sleeve can enter the geometric center of the vertebral body after passing through the upper back edge of the vertebral body to puncture the target point, and the leakage is not easy to occur after the bone cement is injected at the part.
