In this utility model, be provided with multidirectional articulation joint and there is hinged and joint device locking function, both can realize valgus deformity correcting function in ankle, can effectively be locked in orthopedic rear enforcement again.
This utility model can make mechanical energy (mechanical environment) and bioenergy (tissue regeneration) have the good compatibility (reasonability of Mechanobiology environment), and can meet fracture early implementation strong flexible fastening, later stage fixing, that provide axially mid-term and combined stress stimulates provides balance fixing requirement.
This utility model has carried out new innovation to the mechanics effect of bone external fixator, has dynamic elasticity drawing-off function, has the structure of complying with biological requirement, makes the bone external fixator bionic boundary of marching toward become possibility, for implementing cybernetics, provides technical guarantee.
This utility model has incorporated the structural element of more Ilizarov external fixator, not only in rationale, there is again new breakthrough the aspects such as apparatus innovation, technical specification, clinical practice and treatment theory, substantially realize theoretical system, apparatus seriation, regularized operation, criterion of therapeutical effect, formed new bone External technique system.
Quick-expansion bar in this utility model is the important component of implementing overall configuration and function combinations, can carry out the optimum organization of configuration, increase practicality and the dexterity of configuration, at therapeutic process, can require to implement drawing-off, pressurization, regulation and control elasticity and adaptability rigidity according to treatment fixes, embodied highlightedly bionics function, improve the compatibility of mechanical energy and bioenergy, met the requirement of regeneration reconstruction and control theory, guaranteed curative effect.
In therapeutic process, according to treatment requirement, can control the quick-expansion bar in this utility model by pressure controller, make quick-expansion bar implement elasticity drawing-off pressurization, flexible fastening (regulation and control elasticity) and adaptability rigidity and fix.
Quick-expansion bar in this utility model can stretch, clockwise or rotate counterclockwise lock-on connection 360 degree, quick-expansion bar can increase or shorten, solved the difficult problem that the fixing rigidity of bone external fixator can not change, so can require implement the adaptability balance that gap is zero early stage strongly fixes, mid-term, gap was 1～2mm flexible fastening and later stage gap are 3～5mm according to treatment at therapeutic process, fixed.
Quick-expansion bar in this utility model has quick-expansion, slowly extend and three kinds of functions of dynamic elasticity drawing-off pressurization, there is adjusting operation convenient, configuration is optimized, practical, dexterous feature, more importantly, in the overall process for the treatment of, early, in, the difference in later stage is the stage fixedly, under the prerequisite of repertoire that keeps bone external fixator, can meet respectively early stage strong fixing, flexible fastening in mid-term, later stage balance is the treatment requirement of stage bone fixedly, promote new bone growth, sclerotin mineralising, realize optimized reconstruction and the actively rehabilitation of bone function, realize healing completely, facilitate management after operation simultaneously, be convenient for measuring.
Compare with traditional extension rod (Chinese patent application that application publication number is CN102860861A), the quick-expansion bar in this utility model is use better, specific as follows:
What 1, traditional extension rod adopted is the structure of two-stage nitration bar, there is the problem that dilatability is little, and quick-expansion bar in this utility model has adopted the structure of three sections of bars, so tensile elongation has increased a lot (collapsing length is larger) than traditional extension rod, can reach 160mm～350mm, adjusting range is wider, to ankle is orthopedic, has a very large advantage, has avoided the drawback of the limited length of traditional extension rod.
2, traditional extension rod is carried while shrinking locking jaw, is easily made the screw thread in locking jaw fasten threaded rod, make threaded rod and bar cover locking on lock sleeve, simultaneously, after traditional extension rod is locked by locking jaw, the fit clearance between threaded rod and bar cover can cause extension rod to occur that slight rolling is dynamic.Quick-expansion bar in this utility model has been cancelled locking jaw, so there will be stuck problem while having avoided threaded rod and locking jaw flexible, simultaneously, quick-expansion bar in this utility model has designed outer bar cover and the cooperation of interior bar cover gapless is free to slide, and control by lock-on connection the slip that outer bar overlaps and interior bar overlaps, with this, realize fast significantly length adjustment, owing to being being free to slide of gapless cooperation between interior bar cover and outer bar cover, so locking is rear without rocking.
3, avoided traditional extension rod inconvenient problem with use.Rigidity controller on traditional extension rod is to place separately, when it withstands locking jaw, could realize rigidity and control, during use, adjust complexity and lose time, if while not needing rigidity controller, must be unloaded, so while using not isomorphism type, must add to consider, and this utility model has adopted the built-in principle of rigidity controller, rename as pressure controller, by the pressure in rotational pressure controller, control cover, can adjust the pressure of this utility model to art bone, by the adjusting sleeve in integral-rotation pressure controller, can make to realize flexible fine setting between threaded rod and interior bar cover, so both improved and regulated the speed, guaranteed again to adjust the degree of accuracy of pressure, if while not needing rigidity to control, can directly pressure be controlled to cover and rotate the bosom to adjusting sleeve, Compress Spring is depressed into the shortest, the elastic force of Compress Spring is inoperative, now pressure controller is inoperative, but the effect of being locked is constant.
4, traditional extension rod is when processing locking jaw, difficulty of processing is large, finished product rate is low, production cost is high, become the bottleneck that affects product promotion, and quick-expansion bar in this utility model has been cancelled locking jaw, has reduced difficulty of processing and production cost, improved working (machining) efficiency, the problem of having avoided processing locking jaw to bring.
5, traditional bone external fixator all adopts rustless steel, in therapeutic process, can affect x-ray fluoroscopy, and in this utility model, except threaded rod, all can adopt lightweight duralumin, hard alumin ium alloy, titanium alloy or carbon fibre material, so expanded x-ray fluoroscopy scope, increase the perspective rate of bone external fixator, be convenient to therapeutic effect to carry out accurate assessment, also be more conducive to diagnose exactly the situation of fracture, reduce significantly in addition the weight of bone external fixator, be convenient to functional training.
