Abstract
The utility model relates to a simple bone fracture external fixation frame, which mainly comprises a long bar, a short bar, and scales and sliding adjusting groove on bars. A single-side rack is arranged in the adjusting groove, and the long bar and the short bar are connected and fixed as a whole by a guide fixing axle and a leading pressure amplifying device. A needle-locking device is equipped in the adjusting groove, with a bone needle penetrated. The utility model is reasonable in design, firm in fixation, and convenient in combined use. The long bar and the short bar can be made any longer or shorter along the axle by the leading pressure amplifying device, resolving the problem of fracture overlapped displacement and separated displacement. The flexivity of the bone needle can be appropriately adjusted by needle locking device, which gives suitable physical stress stimulation to fracture section, benefiting good blood circulation of fracture end with rapid heal and good function recovery. With stable pressure separation, the utility model can be pre-operation designed for bone needle positioning, efficiently avoiding estimate of bone needle positioning before operation. The fixation frame is an ideal external fixation device which is used for fracture treatment, shape righting, bone disease, and bone extender.
Description
Technical field
This utility model relates to a kind of synthetism apparatus, particularly simple and easy external fixation of fracture frame.It is applicable to treatment fracture, orthopedic, osteopathia and bone prolongation etc.
Background technology
Usually, when fracture was carried out the bone reconstructive therapy, the external fixation bone reduction apparatus kind of employing was a lot, and at present, " the single armed external fixer " of Ying Yonging is exactly wherein a kind of clinically.This external fixer comprises the purl device that spicule, pressue device and pressue device two ends connect by universal joint.Said purl device is made of purl sheet and the pressurization screw that is locked.Said pressue device is by outer sleeve, penetrates the interior axle of outer sleeve, and the trip bolt of the two of fixing them, and the pressurization connecting rod that the two is connected with them constitutes.Though this external fixer can vertically pressurize, the monoplane fracture fixation, longitudinally adjustable range is short for it, has only 2cm, can not or shorten according to clinical needs combination in any lengthening, and the fixed position of spicule can not arbitrarily be adjusted.Simultaneously, its complex structure, cost height.
The utility model content
The purpose of this utility model is to provide a kind of simple and easy external fixation of fracture frame, it can overcome the deficiency of prior art, can elongate or shorten according to clinical needs combination in any, regulate the fixed position of spicule arbitrarily, also but the location of design spicule before the art avoids art preceding to the localized estimation of spicule effectively.
Its solution is: be provided with rule and slippage regulating tank on long-armed connecting rod and galianconism connecting rod, in two slippage regulating tanks, be provided with corresponding monolateral tooth bar, and long and short arm connecting rod overlaps mutually and is connected as a single entity with the traction pressue device by the guide securement axle, and in two slippage regulating tanks, the purl device being installed, cross-under has spicule on it.Said traction pressue device is made of pressuring shaft that has gear and locking nut.Said purl device is made of the purl axle and the locking nut that have the purl hole.
This utility model mainly is that long and short arm connecting rod is provided with rule and slippage regulating tank, monolateral tooth bar is arranged in this regulating tank, and long and short arm connecting rod overlaps mutually with the traction pressue device through the guide securement axle and is connected as a single entity, and the purl device of cross-under spicule is installed in the slippage regulating tank.This external fixer, it is reasonable in design, and is fixed, be used in combination conveniently, according to clinical needs, under the effect of traction pressue device, long and short arm connecting rod axially can be transferred long or shortening arbitrarily along it, to solve overlapping displacement of fracture and shift separation, in conjunction with adjusting purl device, the amount of deflection that can suitably regulate spicule, thereby the physiological stress that obtains suiting on the fracture face is stimulated, help the good blood fortune of bone stump, make union of fracture fast, functional rehabilitation is good.Its separating stable that pressurizes, but the location of design spicule before the art can be avoided before the art effectively to the localized estimation of spicule, and can adjust the fixed position of spicule according to clinical needs arbitrarily.It is a kind of desirable external fixation device that fracture, orthopedic, osteopathia and bone prolong for the treatment of.
Description of drawings
Fig. 1 is the structural front view of simple and easy external fixation of fracture frame.
Fig. 2 is the A-A cutaway view among Fig. 1.
The specific embodiment
The specific embodiment of the present utility model is described in detail in conjunction with the accompanying drawings.
Among Fig. 1, Fig. 2, a corresponding surface of long-armed connecting rod 7 is provided with elongated slippage regulating tank 6, an interior monolateral tooth bar 8 that is provided with of this regulating tank, and another corresponding side surface is provided with rule, is used to design the fixed position of spicule.One corresponding surface of galianconism connecting rod 1 is provided with elongated slippage regulating tank 4, the one interior monolateral tooth bar 5 that is provided with of this regulating tank, it with long-armed connecting rod 7 on the 8 corresponding and uses that match of monolateral tooth bar, and another corresponding side surface is provided with rule, its use that matches with rule on the long-armed connecting rod 7.Long and short arm connecting rod 7,1 overlaps mutually, and connects as one by far away, near-end guide securement axle 10,12 and traction pressue device 9.And traction pressue device 9 is made of the pressuring shaft 15 and the locking nut that have column type gear 11.Pressuring shaft 15 by traction pressue device 9 is meshed with monolateral tooth bar 8,5, and long and short arm connecting rod 7,1 is elongated or shortened vertically.In the slippage regulating tank 6,4 of the other end of long and short arm connecting rod 7,1,2 purl devices 3 are installed, are fixed with spicule 2 by 13 cross-under of purl hole on the purl device 3.Said purl device 3 is made of the purl axle 14 and the locking nut that have purl hole 13.
When clinical practice, can will grow according to fracture situation, galianconism connecting rod 7,1 by long, length, short mode is combined into suitable length, and have far away, near-end guide securement axle 10,12 and the traction pressue device fixedly connected, according to length, galianconism connecting rod 7, the fixed position of the rule design spicule 2 on 1, wear spicule, spicule is penetrated offside cortical bone 1-2 silk, to expose limbs outer end spicule with purl device 3 and be fixed on length, galianconism connecting rod 7, on 1, and suitably regulate the spicule amount of deflection, the pressuring shaft 15 of rotation traction traction pressue device, after the entire pressurisation, fixedly pressuring shaft 15, thereby can make the physiological stress that obtains suiting on the fracture face.So finish bone reduction external fixation one time.
