Abstract

The invention relates to a vertebral body forming support which comprises a main shaft rod, a supporting part and a traction part, the supporting part is arranged at the far end of the main shaft rod and is configured to be radially opened or radially closed when moving relative to the main shaft rod, the supporting part comprises a supporting plate, and when the supporting part is in an opened state, the supporting plate is configured to be used for supporting a vertebral body, the traction part is connected with the main shaft rod and the supporting part and used for controlling the supporting part to radially close or radially open along the main shaft rod. The vertebral body forming support is sent into the vertebral body cavity through the pushing rod in a non-opened state, after the supporting part reaches a designated position, the pushing rod drives the main shaft rod to move, the supporting part is opened in the radial direction when moving towards the near end relative to the far end of the main shaft rod, and when the supporting part is in an opened state, the supporting plate is configured to be used for opening the vertebral body cavity so that the vertebral body cavity can be better supported. If the height is not appropriate, the pushing rod can be acted in the reverse direction, the supporting part is folded accordingly, the opening angle of the supporting part is adjusted by adjusting the main shaft rod to move in the forward direction or the reverse direction, and height adjustment is completed.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a vertebroplasty bracket. Background technique [0002] Vertebral body stenting system (VBS, vertebral body stenting system) is mainly used to treat vertebral compression fractures caused by osteoporosis. The expandable stent is placed into the vertebral body through minimally invasive technology, and the vertebral body is reset through expansion of the stent. After expansion, the stent needs to be retained in the vertebral body to stabilize the expanded vertebral body, prevent further collapse of the vertebral body, and relieve the pain of the patient. After that, bone cement is injected into the vertebral body to restore the height of the vertebral body and relieve the patient's pain. [0003] At present, the existing vertebroplasty brackets have low strength, poor plasticity, and low support force, making it difficult to fully expand the vertebral body. In additi...
