Summary of the invention
For solving the technical problem of above-mentioned existence, this utility model provide a kind of can multi-angle puncture fill and can be good to compression fracture rectification effect Cement fixation device.
For achieving the above object, the technical scheme that this utility model adopts is:
A kind of bone cement injection device, comprise the puncture casing I with central through hole, it is characterized in that: also comprise guide thimble II, elasticity puncture needle, elasticity trachea and flexible injection needle tubing, guide thimble II is the guiding sleeve pipe in puncture casing I that is nested with center axially extending bore, guide thimble II can slide with sleeve pipe I and be rotationally connected, guide thimble II end is guiding elbow, nearly opening part is turn of bilge, opening is towards side, elasticity puncture needle diameter is less than sleeve pipe II internal orifice dimension, elasticity trachea end is provided with sacculus, its pipe diameter is less than sleeve pipe II internal orifice dimension, elasticity trachea is connected with feeder, flexible injection syringe tip is ball-type, multiple opening is set and is distributed on its end and close end position.
Described guide thimble II opening surface is parallel with sleeve pipe II axial line.
Described elasticity puncture needle and elasticity trachea, flexible injection needle tubing outer tube diameter are identical.
The sacculus of described elasticity trachea end is wrapped in elasticity trachea end, and elasticity trachea end arranges multiple gas outlet, and gas outlet is all wrapped up by air bag.
Described puncture casing I outer end is provided with angle draw-in groove, and guide thimble II outer end is provided with handle and fixing strip, and card article can be rabbeted in draw-in groove and guide thimble II and puncture casing I fixed cover to be combined.
Puncture casing I tube wall is provided with scale I, and elasticity puncture needle, elasticity trachea and flexible injection needle tubing outer end are provided with identical scale II.
Work process of the present utility model is:
Puncture casing I is fixed in vertebral body nut, puncture casing I is stationary pipes, by guide thimble II threading I, its guide openings passes sleeve pipe I end, fixed opening towards fixing by sleeve pipe II outer end and sleeve pipe I, penetrate elasticity puncture needle, lesion locations in through vertebral body, and remembered the puncture distance of elasticity puncture needle, be as the criterion with the scale of outer end, extract elasticity puncture needle out, for can directly not penetrated flexible injection needle tubing by the vertebral body compressed and find the scale probeed into, carry out bone cement perfusion, for compressed vertebral body, first penetrate elasticity trachea, and trachea is inflated, its end air bag is made to expand vertebral body cavity, it is made tentatively to reset, by change wear bone cement syringe injection bone cement carry out secondary reset.
The beneficial effects of the utility model are:
Compare existing bone cement injection device, this utility model is undertaken puncturing by adjustment guide thimble II and the adjustment of injection point position, need not withdrawing trocar sheath, elasticity puncture needle and elasticity trachea can go deep into space and interior location carries out linking up and expands, flexible injection needle tubing can position injection according to the identical scale probeed into, operate accurately meticulous, the balloon expandable of elasticity trachea can carry out reset to the vertebral body of compression pathological changes and expand, the quadratic extension Absorbable organic halogens reset effect of bone cement, this device saves operating time greatly, and do not need both sides puncture injection omnibearingly can carry out through perfusion to whole vertebral body each point, decrease the misery of sufferer personnel, improve procedure efficiency, and bone cement perfusion effect is good.
