The invention relates to a multifunctional
vertebral body former, which comprises a
balloon structure and a conveying
pipe structure, the conveying
pipe structure comprises a
shape memory alloy pipe,a sliding block and an outer pipe adjusting
handle, a
balloon outer pipe and a
balloon are sleeved with the
shape memory alloy pipe, and the near end of the
shape memory alloy pipe is fixedly connected with the far end of a sliding block; the near end of the sliding block is detachably connected with the balloon structure through a first clamping lug; the outer surface of the sliding block is provided with a threaded structure, the outer surface of the sliding block is sleeved with an outer tube adjusting
handle with an internal threaded structure, the outer tube adjusting
handle is rotated todrive the sliding block to move front and back, and therefore the protruding amount of the far end of the shape memory
alloy tube relative to the far end of an outer tube and the protruding amount ofthe far end of the balloon relative to the far end of the shape memory
alloy tube are controlled. The multifunctional
vertebral body former is simple in structure and easy to operate, vertebral dilation of a bone
drill and pre-dilation of a
balloon catheter are integrated on one instrument,
surgical operation is simplified, surgical time is shortened, surgical efficiency is improved, and meanwhile physical requirements of doctors and economic burdens of patients are reduced.
