Specific implementation mode
It elaborates below in conjunction with the accompanying drawings to the embodiment of the present invention, the present embodiment before being with technical solution of the present invention
It puts and is implemented, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to down
State embodiment.
As shown in figs 1-9, growth formula bone plate of the present invention, including metal bone fracture plate ontology；Metal bone fracture plate sheet
Body is connected by the first plate body 1 and the second plate body 2, is offered respectively on the first plate body 1 and the second plate body 2 for penetrating synthetism
The location hole 3,4 of screw；The convergence part of first plate body 1 and the second plate body 2 is dovetail slot 5,6 structure of plate, and dovetail slot 5 is opened
It is located on the first plate body 1, the notch of dovetail slot 5 opens up downward, and window 7 is offered on the grooved top plate of dovetail slot 5 and is determined
Position screw hole 8 is bolted with positioning screw 9 in positioning screw hole 8, and being connected side by side on 7 edge of window, there are two the bullets extended into window 7
Property locking plate 10,11, the lower surfaces of two elastic collets 10,11 is both provided with down sawtooth, is arranged under two elastic collets 10,11
Fall sawtooth interlaced arrangement in the horizontal in surface；Plate 6 is arranged on the second plate body 2, the upper surface of plate 6 be provided with
The compatible locking teeth of sawtooth 12.
The transverse shape of first plate body 1 and the first plate body 2 can select with the straight type bone plate of Clinical practice, barrel-shaped connect
The identical cross sectional shapes such as bone plate, crescent bone plate.
Operation principle of the present invention is summarized as follows：
The growth formula bone plate for adapting to skeletal shape, operation forward set screw 9 is selected to be in tightening state in fracture operation first
First plate body 1 and the second plate body 2 are fixed, ensure that growth formula bone plate is in original state in preoperative and surgical procedure（It does not give birth to
Long status, as shown in Figure 1, 2）, growth formula bone plate growth function do not enable.
After completing fixed operation by bone screw between formula bone plate and bone to be grown, removes positioning screw 9 and enable
The growth function of growth formula bone plate makes growth formula bone plate synchronize the length growth in fracture of children healing stage；It continues to complete
Subsequent procedures operate.
Postoperative primary growth formula bone plate is consistent with the function of plain bone plate, and providing stable position for fracture site closes
It is and strength support is provided；Sawtooth and locking teeth 12 of the formula bone plate by elastic collet 10,11 are grown in patient's agglutination
Between mechanical interlocking force locking, active length growth cannot be carried out, to obtain stable skeletal fixation position.
Since bone will produce the natural growth of length direction in fracture of children agglutination, and bone fractures during this
Healing completely is held, enough support forces cannot be provided to meet normal life and movement needs, this grows formula synthetism in the process
Plate starts to play fixed function.
Since the convergence part of the first plate body 1 and the second plate body 2 is dovetail slot 5,6 structure of plate, this structure can be complete
Meeting the first plate body 1 of limitation and the second plate body 2, the offset in other directions will not occur during bone growth, swing, and keep
The mutual direction of motion between first plate body 1 and the second plate body 2 is consistent with bone growth direction.
Reach predetermined value in bone growth strength（The mechanical lock of elastic collet 10,11 fallen between sawtooth and locking teeth 12
Clamp force）Afterwards, growth formula bone plate breakthrough mechanical interlocking power limit proceeds by passive growth, due to elastic collet 10 and snap lock
Sawtooth interlaced arrangement in the horizontal is fallen in 11 lower surface of piece, therefore elastic collet 10 and elastic collet 11 are alternately grown
The mechanical pressure in direction is locked, and reaching prevents 2 retraction function of the first plate body 1 and the second plate body.
The present invention pushes 1 and second plate body 2 of dynamic first plate body to bone length by the extension generated with bone growth
Passive growth is made in direction, enables growth formula bone plate is continual support force is transmitted on bone when bone needs,
Growth formula bone plate is avoided to generate retraction because of support force deficiency.
It heals completely, after limbs of patient functional rehabilitation after fracture wound, doctor only need to routinely perform the operation, and requirement is in due course to be carried out
Bone plate removes operation.
It is passively grown, and can not returned under external force by set direction with children's bone growth by growing formula bone plate
The characteristic of contracting realizes that restoring whole position to fracture of children fixes, and adapts to fracture of children convalescence strength and needs and provide branch
Support force is the initial design direction of the present invention.The side that this example is alternately locked by dovetail chute mechanical structure and elastic collet
Method realizes this function, so that this product is efficiently accomplished growth period fracture wound and fixes, and implantation material is effectively prevent to cause children
The obstruction of bone normal growth has prevented cacomelia growth and limbs and has been caused again due to bone plate strength is insufficient or excessively limits
Secondary fracture；It avoids and is not suitable with symptom because bone plate excessively limits the other of bone growth generation, and whole process will not be because of patient
Bone growth strength is excessive to cause the malpractices such as the disconnected plate of broken nail.
