A steerable curved vertebral infusion device according to claim 5, wherein the outer diameter of the outer extruded catheter is 2-3mm, the inner diameter of the outer extruded catheter is 1.5-2.5mm, the outer diameter of the inner extruded catheter is 1.8-2.5mm, the inner diameter of the inner extruded catheter is 1.5-2mm, the outer diameter of the metal tube is 1-2mm, and the inner diameter of the metal tube is 0.8-1.5 mm.
7. A steerable curved vertebral infusion device as in claim 5, wherein the metal tube is provided at its lower end with a metal member, the metal tube lower end, the inner extruded catheter lower end and the balloon lower end being ultrasonically or laser welded together, the outer extruded catheter lower end and the balloon being ultrasonically welded together.
8. A steerable curved vertebral infusion device as in claim 7, wherein a protective wire is provided within the second channel for connecting the metal member and the adjustment handle.
9. A method of perfusion using the steerable curved vertebral perfusion device of any of claims 1-8, comprising the steps of:
the method comprises the following steps: drilling a hole in a vertebral body by adopting a controllable bent vertebral body shaper to establish an arc-shaped channel, wherein the arc-shaped channel can accurately position the central position of the vertebral body, and the controllable bent vertebral body shaper is taken out after the positioning is finished;
step two: the controllable curved vertebral body perfusion device is conveyed to a designated position along the arc-shaped channel;
step three: the bending degree of the bent pipe is adjusted through an adjusting handle;
step four: the sacculus is expanded under high pressure through a pressure pump, and a cavity is integrally formed in the center of the centrum;
step five: the syringe is connected on the connecting head, the bone cement is filled into the bone cavity through the syringe through the metal tube, and the controllable curved vertebral body filling device is taken down after filling, so that the preset operation is completed.
10. The perfusion method of the controllable curved vertebral perfusion apparatus according to claim 9, wherein the controllable curved vertebral shaper includes a shaper adjustment handle having a shaper guide tube at a lower end thereof, a shaper bend tube at a lower end thereof, a shaper metal member at a lower end thereof, and a lower end surface of the shaper metal member being an inclined surface.
