Description
Technical field
The present invention relates to a kind of external fixer, be specifically related to a kind of closed reduction external fixation of fracture frame.
Background technology
Sudden, the fierce antagonism of tech war and damage property enlarge markedly than the war under the routine techniques condition, and the space, battlefield is expanded, and course of war is accelerated, and nonlinear dispersion operation becomes the main mode of operation day by day.Therefore, modern war wound has the many characteristics of multiple injury, combined injury and severe trauma, wherein occupies critical role in the battlefield wound treatment of long bone of limbs fracture.Rescue and treatment of the wounded situation is seen from the war several times of external 80-90 age, to wartime the reduction of wounded's limb fracture fixing all after field operations medical team is with the technical finesse of external fixation of fracture frame, the transfer base hospital has preserved life and limb preservation to greatest extent.The closed reduction external fixation of fracture of field operations frame be according to wartime trauma fracture characteristics develop a kind of portablely, have the closed reduction external fixer of the ring-like fracture of six-freedom degree.Can be fast under the lowered in field environment to the long bone of limbs fracture site closed reduction fix, have that unique reduction is fixing once accomplishes function, postoperative makes things convenient for wounded's action and shifts.
The long bone of limbs fracture is occupied critical role in trauma care.Around the selection of fractures method, various different opinions are arranged always for a long time.The opinion operative treatment that has is to reach satisfied para-position, and the opinion non-operative treatment that has to reduce the complication of bringing because of operation as far as possible.Yet two kinds of sayings all have its reason, and its drawback is arranged again simultaneously.The external fixation of fracture frame adopts closed reduction, and closure is threaded a needle, and external fixed operation method has significantly reduced a series of complication of bringing because of open reduction.External fixer under the modern technologies condition, its biomechanics design can reach the requirement of early function exercise fully, thereby obviously improves the limb function after the union of fracture.Particularly to some advanced ages, serious internal disease is arranged and can not tolerate the fracture patient of major operation.To comminuted fracture, open fracture, the fracture wounded of firearm injury and heavy contamination, external fixation more have its original therapeutic effect.Therefore the bone external fixer can make fracture keep good para-position, does not increase the wound of body again, can keep the good blood fortune of fracture end, can make the patient carry out joint motion in early days again.At present, also do not have a kind of be applicable to that the open-air fracture wounded use light, be easy to carry, can multidirectionally regulate, versatility external fixation of fracture frame preferably.
Summary of the invention
The present invention for solve do not have at present a kind of be applicable to that the open-air fracture wounded use light, be easy to carry, can multidirectionally regulate, the versatility problem of external fixation of fracture frame preferably, and then a kind of closed reduction external fixation of fracture frame is proposed.
The present invention addresses the above problem the technical scheme of taking to be: the present invention includes two bases, slide block, first rotating ring, second swivel becket, spicule upper and lower displacement device, two guide rails, two spicule cross directional stretch devices, two last stocks, two following stocks, two spicule longitudinal stretching devices and several screw thread spicules; Two guide rails laterally arrange side by side; Each is connected with a base respectively at the two ends of each guide rail; Slide block set is contained on two guide rails, and first rotating ring is installed on the slide block, and second swivel becket is installed on the base; Going up stock for two laterally arranges side by side; Two following stocks laterally arrange side by side, go up stock and cuboid of two following stocks formation for two, and an end of stock is connected with first rotating ring on each; The other end of stock is connected with second swivel becket on each; Each down an end of stock be connected with first rotating ring, the other end of each time stock is connected with second swivel becket, parallelly side by side on first rotating ring is provided with two spicule cross directional stretch device supports; And two spicule cross directional stretch device supports are between stock on two and two following stocks; On each spicule cross directional stretch device support a spicule cross directional stretch device is installed respectively respectively, the upper end of each spicule longitudinal stretching device is sleeved on one and goes up on the stock, and the two ends on spicule upper and lower displacement device top respectively are sleeved on one respectively and go up on the stock; And spicule upper and lower displacement device all is equipped with the screw thread spicule on spicule upper and lower displacement device, two spicule cross directional stretch devices, two spicule longitudinal stretching devices between two spicule cross directional stretch devices and two spicule longitudinal stretching devices.
The invention has the beneficial effects as follows: the present invention is simple in structure, cost of manufacture is low, intensity is high, good biocompatibility, in light weight, no X line block, can assemble fast; Be easy to carry and can multidirectionally regulate; The present invention can carry out accurately fixing rapidly to the wounded's fracture site; Significantly reduced a series of complication of bringing because of open reduction, the present invention can reach the requirement of early function exercise fully, thereby obviously improves the limb function after the union of fracture; Particularly to some advanced ages, serious internal disease is arranged and can not tolerate fracture the wounded of major operation; The present invention has better therapeutic effect to fracture the wounded of comminuted fracture, open fracture, firearm injury and heavy contamination, can make fracture keep good para-position, does not increase the wound of body again; Can keep the good blood fortune of fracture end, can make the wounded carry out joint motion in early days again.
