Screw (1): there is external screw thread on the surface, right-hand member has the conical surface, annular groove, screw (1) passes movable block (3) left end through hole, screw (1) right-hand member annular groove cooperates with movable block (3) through hole, and screw (1) conical surface is stuck in the groove of movable block (3) center, prevents that screw (1) from withdrawing from movable block (3), left end has interior hexagonal hole, be convenient to apparatus and hold and get, screw (1) can be designed plurality of specifications, selects for use during for operation.
Merge body (2): right-hand member is an arcuation, left end has fluting, the screw thread step through-hole, the center is a hollow structure, front/rear end has groove, the groove left end has two drift slots, and right-hand member has sloping platform and fluting, fusion device has elasticity, right-hand member inwardly closes up, merging body (2) upper and lower end face is arcuation and pawl is arranged, in the process of strutting, initiatively embed soleplate, more powerful timely antiskid effect is provided, prevent to withdraw from after fusion device from implanting, movable block (3) inserts wherein by the groove that merges body (2) front/rear end, screw (1) is along the screw thread stepped hole precession of merging body (2) left end, adjustment screw (1), promote movable block (3), movable block (3) right-hand member sloping platform place is inserted merge body (2) right-hand member fluting place, fusion body (2) is expanded gradually, adjustable expanded fusion device can be realized the adjustment of 0 °～15 ° of scopes, strut vertebral body, until reaching the operation Expected Results, adjustable expanded fusion device is applicable to the patient of different radian demands, to recover patient's normal physiological curvature, merge body (2) and can design plurality of specifications, select for use during for operation.
By diagnosis such as CT or X-ray vertebra disease before the art, the operation of enforcement thoracic and lumbar vertebral posterior: the intervertebral disc and the vertebral body sections of excision or cleaning damage, determine that according to patient main suit and diagnostic result institute's fixed-segment, used implant comprise the size and the quantity of adjustable expanded fusion device.At first determine the degree of depth and the orientation that adjustable expanded fusion device is implanted, on vertebral body, implement boring, be screwed into the vertebral body nail, intervertebral space struts, and regulates dilator, and disc height is recovered, select die trial according to strutting intervertebral height, determine to implant size, implant adjustable expanded fusion device, clog broken bone, adjustment screw (1) expands fusion body (2) gradually, regulate adjustable expanded fusion device, strut vertebral body, until reaching the operation Expected Results, to recover patient's normal physiological curvature.
Adjustable expanded fusion device is when thoracic and lumbar vertebral posterior is performed the operation, has structure rationally, simple operation, adjustable expanded advantage, adjustable expanded fusion device simple operation practicality, advanced design, damage are little, be easy to strut disc height, promote to merge, be easy to recover and keep the vertebra physiology and appearance, be suitable for the orthopaedics clinical application.
