Description

technical field [0001] The invention relates to the technical field of vertebral body puncture, in particular to a directional expansion balloon system for vertebral body unidirectional puncture. Background technique [0002] Kyphoplasty involves placing a balloon into the osteoporotic site through vertebral puncture, and compressing the internal bone through balloon expansion. After the compression is complete, the balloon is removed from the vertebral body and filled with bone. Cement, bone cement can strengthen the vertebral body after solidification. Kyphoplasty is divided into unilateral puncture and bilateral puncture. Bilateral puncture can make the bone cement evenly distributed, but the bone cement on both sides of the vertebral body diffuses to The mosaic link in the midline area is slightly difficult, and the operation is cumbersome, time-consuming, and the operator is exposed to a large amount of radiation, which is not easy to heal after surgery. Unilateral pun...

Problems solved by technology

[0002] Kyphoplasty is to put the balloon into the osteoporotic position through vertebral body puncture, and compress the internal bone through balloon expansion. After the compression is completed, the balloon is taken out from the vertebral body and filled with bone Cement and bone cement can strengthen the vertebral body after solidification. Kyphoplasty is divided into unilateral puncture and bilateral puncture. Bilateral puncture can make the bone cement evenly distributed, but the bone cement on both sides of the vertebral body diffuses to The mosaic link in the midline area is slightly difficult, and the operation is cumbersome, time-consuming, and the operator is exposed to a lot of radiation, so it is not easy to heal after surgery

However, unilateral puncture can directly establish the channel to the midline area of ​​the vertebral body, which takes less time. However, unilateral puncture controls the puncture angle more strictly. Once the angle is determined, it is inconvenient to adjust the angle of the balloon after puncture, and the angle is frequently corrected. It will cause the risk of microfracture of the pedicle. In addition, a single puncture will also cause poor diffusion of bone cement on both sides, weaker than the midline area, and the direction of balloon expansion cannot be controlled.
