Description
Technical field
The present invention relates to a kind of carpal joint traction fixation frame, is the combination type carpal joint traction fixation frame that a kind of three-dimensional is threaded a needle fixing specifically.
Background technology
The radius far-end fracture sickness rate is very high, and human beings'health and living standard in serious threat.The external fixer that is fit to be applied in wrist stationary applications treatment radius far-end fracture both at home and abroad is the single armed frame.The single armed frame all is that screw is fixed with half aciculiform formula, to be fixed as major function.Though the single armed external fixer is more convenient, because be that arm of force formula is fixed, stability in the large and performance-adjustable are poor.Do not have yet and to draw and the fixing function that resets sclerite, limited the application of external fixer in the wrist fracture.
Summary of the invention
In order to solve carpal joint external fixer structure coarse-pitch thread nail fixation problem in the prior art.The purpose of this invention is to provide a kind of compact conformation, stable, fixed with patient's carpal joint three dimensions, use, dismounting is convenient effectively fixing carpal fracture, traction, the effective combination type carpal joint 3 d traction fixed mount of fixation for treatment
The technical solution used in the present invention is: a kind of carpal joint 3 d traction fixed mount, mainly comprise two connecting rods each one and two camber rings, two camber rings are along being equipped with a plurality of through holes on the end face of arc direction, the two ends of every connecting rod are locked respectively and are connected on the corresponding through hole of two camber rings, be equipped with two purl screws on each camber ring, be equipped with the groove of threading a needle on the end face of purl screw near its bolt part, the bolt of purl screw through nut check on the camber ring, first Kirschner wire passes the first purl screw on the first camber ring groove of threading a needle successively, the metacarpal bone neck, thread a needle groove and by nut check first of the second purl screw, the bolt of two purl screws is pressed on first Kirschner wire on the first camber ring, and second Kirschner wire passes the 3rd purl screw on the second camber ring groove of threading a needle successively, radius, thread a needle groove and by nut check the 3rd of the 4th purl screw, the bolt of four purl screws is pressed on second Kirschner wire on the second camber ring.Two camber rings connect into fixed mount through two connecting rods, first and second purl screw on the two camber ring end faces is locked first and second Kirschner wire that passes metacarpal bone neck and radius respectively, and fixed mount is fixed carpal joint in three dimensions through Di Yi,Er Shi pin, carbon fiber connecting rod.
Described two connecting rod two ends are connected on the two arc rings through L type connecting rod respectively, and on the arc ring, the other end of L type connecting rod passes upper and lower connecting rod folder through nut check to an end of L type connecting rod through nut check, and its upper and lower connecting rod folder clamps connecting rod.
Held upper and lower connecting rod folder on described arbitrary connecting rod tightly, the 5th purl screw passes upper and lower connecting rod folder through nut check, and cross-under has the thimble of bone fixation folded block in the groove of threading a needle of the 5th purl screw.The 5th purl screw lock thimble penetrates the wrist fracture piece of damage on the connecting rod, according to the different degree of impairments of carpal joint, adopts 1-2 root thimble that the wrist fracture piece is fixed respectively; Upper and lower connecting rod folder can be different angles and clamp L type Connection Block connecting rod or connecting rod, cooperates the 5th purl screw lock fixing towards the wrist fracture piece that changes the various orientation of adaptation, angle.
Described arbitrary connecting rod is provided with thread segment, the thread segment diameter is less than the diameter of connecting rod straight bar part, be connected with circular adjusting nut and the adjusting lock nut of the upper and lower connecting rod folder two sides that push against duralumin connecting rod thread segment respectively on the thread segment, the periphery of circular adjusting nut is provided with lock-screw.Drip at the circular adjusting nut of thread segment adjusted and to push against the side that upper and lower connecting rod folder is held duralumin connecting rod thread segment tightly, regulate upper and lower connecting rod folder and hold the position tightly, make the distance between the two arc rings adjustable, realize reduction by traction.
Through hole is the combination in any of any one or both in circular apertures, the waist-shaped hole on the described camber ring.During use, according to the different situations of patient's ankle joint, L type connecting rod or L type Connection Block fixed position activity change on the arc ring, applied widely.
Described connecting rod is carbon fiber connecting rod or duralumin connecting rod.
After adopting above technical scheme, the invention has the beneficial effects as follows:
1, fixed mount adopts each one on carbon fiber and duralumin connecting rod to be connected two arc rings, under the prerequisite that fully satisfies strength of materials requirement, can avoid the photograph occlusion issue of fracture site greatly, improve the diagnosis of postoperative iconography, and the steel connecting rod was light more in the past, the patient burden is light, provides advantage for early functional exercise reaches early stage examination heavy burden;
2, fixed mount arc ring is provided with the purl screw, Kirschner wire is threaded a needle fixing through the purl screw lock to metacarpal bone, radius three-dimensional before and after the carpal joint, fixed mount arc ring adopts L type connecting rod to connect carbon fiber connecting rod simultaneously, the installation site of scalable L type connecting rod a plurality of through holes on the arc ring and the fixed angle of L type connecting rod, can be from many planes, multi-facetedly provide favourable and lasting bed knife for the part of fracturing, fixed mount three dimensions stability is strong, can patient's carpal joint is fixed, avoided the fixing and uncontrollable deficiency of rigidity of traditional monolateral thick nail;
3, fixed mount is to penetrate first and second Kirschner wire successively at metacarpal bone, radius away from the wrist fracture part, destruction to the wrist fracture local soft tissue can be reduced away from carpal joint in the position of threading a needle, be conducive to the local blood fortune of protection fracture and the protection of self soft tissue, accelerate the wrist fracture healing, and can produce adaptability to changes to fracture end by stable fixing, stimulate osseous tissue growth accelerating union of bone fracture;
4, the fixed mount carbon fiber connecting rod is provided with one or more purl screws, the purl screw is through last, movable being fixed on the carbon fiber connecting rod of lower link folder, according to wrist fracture situation and fracture, match one or more draw point and after the purl screw lock, be diverse location in carbon fiber connecting rod, different angles are fixed the wrist fracture piece, the local sclerite realization of carpal joint acupuncture needle is dialled bone, it is fixing to thread a needle, need not extensively to peel off periosteum, flexible operation, the operating time section, go out insufficiency of blood, be conducive to growth of spur, union of fracture has reduced infection rate simultaneously;
Fixed mount of the present invention adopts two Kirschner wires through the purl screw lock metacarpal bone neck, radius to be threaded a needle to cooperate and fixes, cooperate draw point through the purl screw lock wrist fracture piece to be fixed, compact overall structure, stable, use, convenient disassembly, use cost is low, and auxiliary fixing to carpal joint and sclerite, rigidity is adjustable, need not the peeling operation periosteum, be conducive to the recovery from illness of carpal joint damage.
