Description
Technical field
The present invention relates to the device of orthopedics clinic practice, more particularly to a kind of pressure-adjustable hold-down bars, and the elasticity including pressure-adjustable hold-down bars is interior solid
Determine system.
Background technology
When human limb long bone is fractured, often need to reset fracture, fix, corresponding technique for fixing and material are also constantly entering
Step is with updating, such as steel plate, intramedullary nail, exterior fixing rack, and conventional internal fixation device is steel plate at present, and its fixed range of performing the operation is big, soft tissue
Peel off many, wound big, the drawback such as malreduction；Postoperative presence occurs osteoporosis, even fixture loosening, inside-fixture due to stress shielding
Curative effect must not be had a strong impact on after the drawbacks such as disconnected rod, Unstable internal fixation without second operation even Repeated Operation.
Fracture healing process is complicated, domestic and foreign scholars to the theoretical understanding of union in constantly improve, the sight for the strong fixation of fracture that early stage is advocated
Clinical practice and experimental study of the point by decades confirm that, due to the stress-shielding effect of fixture, osteoporosis easily occurs in fix bone, fixed
The problems such as thing fractures, the biological rational osteopathy viewpoint of proposition is gradually received, and union is by patient age, mechanical environment, local blood
Transport, the factors influence such as endocrine, stress is one of principal element, although existing various fixed apparatus shapes, configurations, can not enter
Row micro-positioning regulators, using when be also easy to produce stress shielding, osteoporosis occur, though have can fine motion, can not precisely limit the scope of fine motion, direction,
And the size of stress.
Stress and union aspect：Bone tissue is a kind of viscoelastic solid material, and mechanical characteristic is complicated, its structure and function and its mechanical characteristics and
Mechanical environment state is closely related, determines that different stress stimulations have Different Effects power to Bone m etabolism and knitting.In terms of stress mechanism：
Intracellular signal transduction pathway in stress influence fracture healing process, can be by positioned at endoglin expression or the calcium channel of cross-film presence, integration
Element, growth factor etc., extracellular matrix signal are transmitted into intracellular.Mechanical signal coupling, cell propagation and the intracellular and cell of Gegenbaur's cell
Between Ca2+The lifting of level is relevant, and integrin is the main matter for contacting intraor extracellular signal, and extraneous tensile stress can be intracellular with induced osteogenesis under stimulating
Physiology, biochemical change, respond and are expressed with conducted signal, activated gene, synthesize and discharge cell factor and hormone, regulate and control to mechanical stimulus
Sensing and propagation, differentiation and mineralising.The characteristics of relative association of integrins expression level has time limit change.Regulation of the stress to osteoblasts metabolism and cell factor
The secretion of growth factor caused by stress can be directly by promoting growth factor or promoting the secretion of the hormone with growth in vivo, indirectly
Promote cell growth, it is the more growth factor of content in Gegenbaur's cell to be converted into the factor, can adjust propagation and the differentiation of Gegenbaur's cell, another
Aspect, promotes synthesis type collagen fiber connection element, promotes Gegenbaur's cell to synthesize type i collagen, fibronectin, osteonectin and proteoglycans.
Research is thought at present in terms of the mode of stress, opportunity, species, size：Intermittent stress stimulation is compared with continuity stress stimulation more
Osteoblast activity can be excited；Research thinks that knitting early stage promotes the most effective period of knitting for mechanics factor, when union recovers original
After structure and hardness, mechanics factor is the single factor of bone remodeling, and knitting early stage should ensure that appropriate stress and strain between fracture site, knitting
In early days, the compression that axial load is produced can drive Gegenbaur's cell and fibroblast to develop to differentiation skeletonization direction, favourable to knitting, shearing and
Torsional load produces shear stress, preferably causes fracture end dynamic friction, has the capillary and poroma of formation compared with major injury, and drive fibroblast
Propagation, produces fibr tissue, is unfavorable for knitting, has certain promotion to the formation of poroma and reconstruction in knitting middle and later periods various stress；
Knitting needs appropriate biomechanical environment or optimum stress level, only when fracture end stress level and healing district's groups knit the mutual balance coordination of rigidity
Organizing ability's well differentiation and healing, stress is excessive, more than tissue ability to bear, and live body bone will occur at bone-to-bone interface or bone-inside-fixture interface
Reactive surfaces absorb, and fracture end pressure reduces, and causes osteanabrosis, and pressure is bigger, and fracture end pressure reduction is rapider, conversely, being not enough to draw
Play elastic deformation, tissue differentiation mechanics induction reduction, it is difficult to produce, bone delay in healing, bone nonunion may be caused.Typically think fracture end compression
It is advisable no more than physiology body weight.
Fine motion and union aspect：Fracture end fine motion is maintained close ties with stress, is confirmed according to Wollf laws and recent many researchs, fracture
The suitable fine motion of end controllability can promote the formation and calcification of poroma, and accelerating union of bone fracture is ground at present in terms of the frequency of fine motion, opportunity, amount
Study carefully and think：Fine motion on low-frequency axial direction is favourable to union, and early stage Micromovement can promote union, late period (4-6 weeks)
The fine motion easy damaged fracture site rete vasculosum of generation, postpones union.
The content of the invention
The defect existed it is an object of the invention to make up currently used internal fixation device treatment limbs fracture has there is provided one kind can adjust pressure
, fixation, simple to operate, regulation readily elastic internal fixation system and pressure-adjustable hold-down bars, effectively prevent stress shielding, it is to avoid sclerotin is dredged
Pine, accelerating bone healing.
