Description
Technical field
This utility model relates to traditional Chinese medical science Set by small splints from outside therapy system, and specifically, this utility model relates to a kind of biological truss structure formula plintlet component for External fixation bone injury disease and has its traditional Chinese medical science plintlet device.
Background technology
Clamping plate local extenal fixation is the characteristic of Chinese medicine treatment fracture, the theoretical system having it complete and Therapeutic Principle.Be different from other any extenal fixation pattern.Because of region or the difference of drawing materials, have north and south group point, south group is with Cortex Cunninghamiae Lanceolatae plintlet for representative, and north group is representative with Willow splint, and two kinds of clamping plate are straight strip-shaped, have certain rigidity, toughness and elasticity, differ from one another.Contain the principle of " flexible fastening ", and the Therapeutic Principle of " axially hold bone, laterally fixing " and the biological External fixation pattern of " be association of activity and inertia, muscles and bones is laid equal stress on ", meet the objective law of union of fracture.World's orthopaedics and tranmstology treatment field is created to the impact of directiveness.But, the using state of current domestic traditional Chinese medical science plintlet does not but make us optimistic, with advance by leaps and bounds now, the west osteopathy that research field is constantly expanded is compared, the development of traditional Chinese medical science plintlet technology relatively lags behind, there is the contradiction between advanced treatment concept with the relative treatment means fallen behind, and many insoluble problems.Except outside fixing operation pattern and overall structure, the mechanical property of cleat member is unstable, is one of subject matter without standard.Especially, the straight plate shape of clamping plate, only can be used for the treatment of shaft fracture, limited to articular fracture treatment, there is shortcoming remote.Carry out closed reduction with TCM bone-setting skills to articular fracture, its effect is also not less than operative treatment, but existing plintlet system but can not meet the External fixation after reset.Some scholars is thought, looks back the developing history of traditional Chinese medical science synthetism, and be heavy maneuver, light fixing leftover problem, causes present situation, but be more the selection of having no way out.Occurred many patented products about clamping plate recently both at home and abroad, wherein plaster splint, macromolecule polyester clamping plate etc. are when extenal fixation uses, can be moulding according to articular morphology, but the extenal fixation pattern that this kind of clamping plate are formed is substantially identical with Gypsum Fibrosum extenal fixation.There is difference in essence with traditional Chinese medical science plintlet elasticity External fixation theory, do not produce the superior therapeutic effect of traditional Chinese medical science Set by small splints from outside.Go through the exploration of more than ten years, Cunninghamia lanceolata (Lamb.) Hook. dermatotome and wicker plate are vertical along Pattern structure, have with straight rigid axle power for dominant shape is orthogonal anisotropic feature.
Though useful gathering moulds ester alloy modification material in prior art, be the engineering mechanics structural simulation natural splint material Shun Pattern structure such as continuous I-shaped, bridge arch shape with cross section, with extrusion process, develop the anisotropic clamping plate of similar natural wood materials, by clinical verification, obtain successfully.But these clamping plate are still straight strip-shaped, vertical just horizontal soft structural behaviour can not meet the External fixation of joint part equally.By in-depth research, recognize, carry out External fixation by traditional Chinese medical science plintlet system to human synovial fracture, clamping plate used must can comply with the biomophic change of human synovial.May because of not enough to the understanding of traditional Chinese medical science plintlet mechanical essence or processing technology is difficult, the clamping plate appearance not having this type of to have Traditional Chinese Medicine plintlet theory so far.
In view of the above, the traditional Chinese medical science Set by small splints from outside treatment field need a kind of can with the plintlet of external treatment of Chinese medicine theory External fixation articular fracture and therapy system device.
