Below as a example by supracondylar fracture of the humerus and oar, ulna fracture of distal External fixation, this utility model is done into One step explanation.

1st, on condyle of humerus the inclined fracture of straight type of chi External fixation；

As a example by chi bias tyre fracture is stretched on children humeral condyle, be always suitable for the treatment of traditional Chinese medical science Set by small splints from outside in the past, But due to Willow splint, fir-bark splint, the biomophic change of elbow joint can not be complied with, outer fixation is unstable, especially not The mechanical requirements of External

Traditional Chinese medical science plintlet component of the present utility model, cleat assembly and traditional Chinese medical science plintlet device, come from utility model people couple Traditional Chinese medical science plintlet mechanical essence and the research of quantitative relationship, by substantial amounts of clinical practice, vicennial research and probe, including such as Modern big data analyzing and processing, it is recognised that the traditional Chinese medical science is used for the Willow splint of external fixation bone-fracture treatment, the mechanical property of fir-bark splint General character and biocompatibility can be there is with the biomechanical property of skeleton.Natural timber taken from by two kinds of clamping plates, and timber is most Junior unit tubular fossils and the little fine strain of millet of the minimum unit bone of skeleton, the interior external callus of strong healing of fracturing are tied with basic function Structure, is parallel to axis direction, and this arrangement mode is principal direction of stress, forms favourable stress, is held with axial force Sheared, resist torque, an excellent load-carrying construction is become with rational section, i.e.,：There is natural Orthotropy jointly Property property.Analyze through big data, why traditional Chinese medical science plintlet achieves biological External fixation theory, including Chinese synthetism Theoretical, it may be said that from Willow splint, fir-bark splint and skeleton mechanics function, the general character of property, including each of muscle Anisotropy.Therefore, the mechanical essence of traditional Chinese medical science plintlet should be：" orthotropy based on axial force ".So-called anisotropy Concept be：The different performance value in mutually perpendicular direction of material.Its quantitative relationship, by these three material structures, Form, function, the dissection of feature, Modeling Research, according to " being association of activity and inertia, muscles and bones is laid equal stress on " principle, the quantitative pass of traditional Chinese medical science plintlet System includes, the ratio of the longitudinal and transverse direction mechanical performance of material.If skeleton is circumferentially and radially the half of longitudinal modulus of elasticity. According to the analysis of Clinical practice big data, the technical connotation of so-called " axially holding bone, laterally fixed ", with " non-functional replacement " theory There is association.The rigidity of the rigidity of external fixation system, elastic modelling quantity and skeleton, elastic modelling quantity have adaptable ratio Value.In outer fixation procedure, the stress-strain relation that the stress-strain relation of external fixation system is rebuild with fracture, including non- The relation of function replacement, mechanical function of the clamping plate in fracture fixation are the mechanics demands according to fracture local stability.Therefore, in The mechanics quantitative relationship of doctor's plintlet, is reduced to from effective angle：" with human body institute fixed position skeleton rigidity, elastic modelling quantity Ratio, the ratio and allowable stress coefficient of longitudinal and transverse (being mutually perpendicular to) the direction elastic modelling quantity of splint material ".With reference to FInite Element Orthotropic Composite structure, parameter identification, set up the constitutive equation of traditional Chinese medical science plintlet, determine that its ess-strain is closed System, the elastic modelling quantity ratio in longitudinal and transverse direction should be 21：1～90：1 is interval.And so-called Set by small splints from outside treatment is explained, it is assorted It is biological therapeutic modality.Clinical investigation finds that use Willow splint external fixation bone-fracture treatment, its rift grain (arrange by tubular fossils Row) direction and the dry bone of fracture site (bone trabecula arrangement) equidirectional when, fixation for treatment best results.The longitudinal direction of fir-bark splint is just Degree is bigger than difference with lateral stiffness, and horizontal hogging moment change is better, and therapeutic effect is also better.It is the first-selection for having experience doctor, is Universal phenomenon.Peek plate shape identical Willow splint, with the distribution that pressure transducer tests its pressure, rift grain is preferably substantially The even clamping plate poor in rift grain.The pressure distribution of fir-bark splint, more uniformly, but transverse strength is poor, easy longitudinal splitting, these Problem so far there are no relevant report and attention.By computer virtual technology Modeling Research, grain direction exactly tubular fossils Axial orientation, and the dry axis of bone of skeleton is to being bone trabecular axial orientation, is both biological functional structures General character.Outside virtuality in fixed test, observe：The compressive stress that clamping plate is produced has directivity, and anisotropic properties are preferable Clamping plate, when fixing outside, such as tubular cylinder orientation is identical with bone trabecula orientation, and forms arcuate sectors, and clamping plate is produced , to key aggregation, the key counter-force through meat fiber generation is corresponding, and human muscle is all anisotropy for raw compressive stress, Tendon fiber is almost substantially parallel arrangement, and when the meat fiber arrangement between clamping plate and backbone is also equidirectional, muscle relaxes contracting activity then For compliance.Clamping plate compressive stress depends on muscle diastole elastic recovery in the horizontal, does not affect flesh into correspondence power alternate Meat relaxes to contract and rises and falls and transverse component, could coordinate muscular contraction force and produce axial compression to fracture end by axial direction, and so-called " sound is tied Close, muscles and bones is laid equal stress on ", its " moving " more importantly shows clamping plate restoring force transversely, ability " muscles and bones is laid equal stress on ".Placing pressure Pad area, is targeting with respect to the efficacy that compressive stress is produced.The compressive stress of the fixation of fracture end should be：Extruding from axial direction Power and from horizontal resistance.The above is biological External fixation feature, on condition that, for making clamping plate Material is homogeneous material, possesses orthotropic mechanical characteristics based on axial force.Tested with isotropic material clamping plate, Above situation is then occurred without." being association of activity and inertia, muscles and bones is laid equal stress on " can be explained further, the machine of " axially holding bone, laterally fixed " Reason, is the description of biological outer fixed form.Thus, the standard of traditional Chinese medical science plintlet should be：The mechanics sheet of traditional Chinese medical science plintlet Matter and quantitative relationship and related qualitative description.Preferably traditional Chinese medical science plintlet is：Willow splint and the mechanics function of fir-bark splint Complex, has abandoned the defect of natural timber, is the rigidity of Willow splint on its mechanical property longitudinal direction, is then laterally Cunninghamia lanceolata (Lamb.) Hook. leather wallet The enhanced pliability of plate.When outer fixed, clamping plate axial direction lever force is axially identical with the lever of fractured bones, by the effect of pressure pad Power, with the horizontal dynamic aggregating that encloses in fracture end, to resist power strenuously, with dynamic braking, that resists fracture end shifts tendency power again.And clamping plate is horizontal To restoring force, the contractility of dynamic equilibrium muscle, clamping plate in the horizontal equally produce elastic potential energy, i.e., so-called elastic recovery Power.The contractility of muscle could be coordinated in the vertical, and axial compression power is produced to fracture end.Therefore this utility model is with above-mentioned two Normal structure of the basic framework for traditional Chinese medical science plintlet is planted, optimized design is close to, using computer virtual modeling technique, by material Material, structure, function set, are produced with the traditional Chinese medical science plintlet component for being adapted function with bone remoulding with modern technologies.
