Abstract
The present invention discloses an appliance which is used for repairing cleft palate and is made from a nickel-titanium shape memory alloy. The appliance is composed of a middle stretching and boosting orthopedic part and retention parts on both ends, wherein the retention parts and the stretching and boosting orthopedic part are not in the same plane, and an included angle of 70 DEG to 120 DEG is formed between the two planes. The appliance is formed by bending a nickel-titanium shape memory alloy wire which is in a partial hardening state, a fixed shape is formed after shaping and shape memory processing, so the appliance has the advantages of small dimensional deviation and complex temperature of 30 DEG C to 35 DEG C. The appliance is characterized in that the stretching and boosting orthopedic part generates stretching force by the transition from the Martensitic phase to the parent phase after the stretching and boosting orthopedic part enters a human body, and the degree of the change of stretching force is small or constant along with the reduction of a crack by the counterfeit elasticity; L-shaped hooks are formed by the retention parts by using the complex of memory effects. The present invention has the advantages of firm retention and difficult shedding.
Description
Technical field
The present invention relates to functional material, two fields of decorative sursery apparatus, be specifically related to a kind of niti-shaped memorial alloy cleft palate and repair appliance and manufacture method thereof.
Background technology
The distraction osteogenesis technology is to utilize the natural sutura of distraction force tractive or the artificial sutura of stretching appliance, in the sutura gap, form new bone, the hone lamella Cleft Palate crack of mobile gradually cleft palate both sides, the crack is dwindled until complete closure, thereby reach the purpose of repairing the homologue defective with homologue.Its effect depends primarily on the big or small and stable of distraction force, promptly depends on the geometry and the size of material property and appliance.Adopt the memorial alloy appliance that has shape memory effect merely, can realize the purpose of automatic driving-force adding.But distraction force will influence later stage distraction osteogenesis effect with the dwindling and reduce of crack width.
Summary of the invention
The present invention proposes a kind of niti-shaped memorial alloy cleft palate and repairs appliance and manufacture method thereof, and this appliance has the afterburning function of automatic stretching, and distraction force is very little with the degree that the crack reduced width changes, and does not influence later stage stretching effect, and is easy to use.
This appliance is made by the nitinol alloy wire of integral body, through being processed into different shapes, forms the maintenance part at afterburning orthopedic part of intermediary stretching and two ends.The former is designed to triangle according to use occasion, perhaps hump shape, and the latter is designed to " L " font, and two parts are coplane not, and the angle between the two sides is 70～120 °.During use, in 0～5 ℃ brine ice, the former is stretched to the setting size, the latter is deformed to linearity or nearly linearity, insert then in the pre-drilled palate plate hole.Under the human body temperature effect, complex is partly shunk in middle stretching, and the traction hone lamella enlarges forming new bone sutura, makes the crack dwindle purpose until closure gradually thereby reach; Maintenance partly is returned to " L " font, forms about 80～90 ° hook, plays the maintenance effect.Behind the closing of fracture appliance being cut off the back takes out.
Niti-shaped memorial alloy cleft palate of the present invention is repaired appliance, is made by the nitinol alloy wire of integral body, through being processed into different shapes, forms the maintenance part at afterburning orthopedic part of intermediary stretching and two ends.The maintenance at two ends part and the afterburning orthopedic part of stretching be coplane not, and the angle between the two sides is 70～120 °.
The afterburning orthopedic part of above-mentioned stretching is a triangle, and the two ends maintenance partly is " L " font, is arranged in parallel.
The afterburning orthopedic part of above-mentioned stretching is a triangle, and the two ends maintenance partly is " L " font, cross arrangement.
The afterburning orthopedic part of above-mentioned stretching is a hump shape, and the two ends maintenance partly is " L " font, is arranged in parallel.
The afterburning orthopedic part of above-mentioned stretching is a hump shape, and the two ends maintenance partly is " L " font, cross arrangement.
Niti-shaped memorial alloy cleft palate of the present invention is repaired the manufacture method of appliance, has the following steps:
(1) nitinol alloy wire that will be in the attitude of to a certain degree hardening is bent into definite shape, controlled deformation amount in this process, make the deflection of the afterburning orthopedic part of stretching bigger, the deflection of two ends maintenance part is less, place shaper to heat-treat then, treatment temperature is 350～700 ℃, and the time is 0.5～3 hour.
(2) the complex temperature is 30～35 ℃, can reply modular shapes when being warming up to 35～37 ℃ after the distortion in the low temperature frozen water, and when this temperature range internal strain, the afterburning orthopedic part of stretching has pseudoelasticity, can reduce the fluctuation of corrective force.
Above-mentioned appliance also can be made by the direct bending of niti-shaped memorial alloy silk, and in this process, the controlled deformation amount makes the deflection of the afterburning orthopedic part of stretching bigger, and the deflection of two ends maintenance part is less.

1 is the afterburning orthopedic part of stretching among the above-mentioned figure, the 2nd, and two ends maintenance part.
The specific embodiment
The niti-shaped memorial alloy silk of employing different-diameter is bent into the orthosis of different shape, the diameter different according to the different choice of use occasion, larger-diameter memory alloy wire can be adopted during the natural sutura of stretching, the memory alloy wire of minor diameter can be adopted during the artificial sutura of stretching.
To be in to a certain degree earlier, the alloy silk of hardening state is bent into definite shape, and put into shaper, again through 350～700 ℃, 0.5～3 hour typing is handled and memory is handled, and makes it have the less solid shape of shape and size deviation and scope 30～35 ℃ complex temperature.
Examples of implementation 1: will be in earlier to a certain degree that the alloy silk of hardening state is bent into definite shape, and put into shaper then, and finalize the design and handle and memory is handled, treatment temperature is 350 ℃, and the time is 3 hours.
Examples of implementation 2:, will be in earlier to a certain degree that the alloy silk of hardening state is bent into definite shape, put into shaper then, to finalize the design and handle and memory is handled, treatment temperature is 500 ℃, the time is 1 hour.
Examples of implementation 3:, will be in earlier to a certain degree that the alloy silk of hardening state is bent into definite shape, put into shaper then, to finalize the design and handle and memory is handled, treatment temperature is 700 ℃, the time is 0.5 hour.
During installation, on the hone lamella of cleft palate both sides, hole earlier, then in 0～5 ℃ brine ice with the afterburning orthopedic part stretcher strain of the intermediary stretching of appliance to a certain degree (depending on crack width and requirement), the maintenance part at appliance two ends is deformed to straight line or nearly linearity by " L " font, inserts then in the above-mentioned pre-drilled hole.Postoperative two ends maintenance part complex is to " L " font, form about 80～90 ° hook, play the maintenance effect, stretching part complex is shunk, and the stretching sutura enlarges, and makes and forms new bone in it, both sides, crack hone lamella moves, the crack width reduces, and until last closed fully, reaches the purpose of repairing the cleft palate bony defect.
