Abstract
The utility model is multi link ring type exterior fixing rack, belong to outer fixed the field of medical instrument technology, suitable for long bone of limbs malformation correction, it is made of hole loopful (1), universal joint (2), extending sleeve component (3), bolt (4), draw point and its attachment is coordinated to complete fixed operation outside long bone of limbs malformation correction, it is characterised in that：Each position number extending sleeve component (3) is slowly adjusted according to the deformities of bone, make the gradual stress of lopsided bone, develop to normal direction, orthopedic effect can be done step-by-step under conditions of maintaining stable growth, restore the normal line of force of long bone of limbs, patient activity's ability is improved, the various psychological burdens brought by bone malformation are reduced, to improve the quality of living.
Description
Technical field
The utility model is related to fixed products outside the ring type of multi link malformation correction, belong to outer fixed medical device technology neck
Domain helps long bone of limbs malformation correction product.
Background technology
The type of fixed product is more and more outside bone, but solid outside fixed or combined type either outside single-side multifunctional
It is fixed, it is not well positioned to meet the treatment for long bone malformation class illness, my company devises on the basis of combined bay thus
A kind of multi link annular external fixing rack can play an irreplaceable role long bone of limbs malformation correction.
Invention content
The utility model is simple in structure firm, and draw point is tiny, threads a needle ingenious, and wound is small, maximum while ensureing curative effect
Limit facilitates patient is postoperative to take care of oneself, functional training, and long-term bed, action caused by complicated is reduced or avoided
Inconvenience, long-term inpatients etc. bring unnecessary pain and the feared state of mind, the life postoperative to patient to bring revolutionary character to patient
Improvement, reasonable design is easy for installation, simple in structure, be suitble to promote and apply.
The technical solution of the utility model is as follows：
The utility model is multi link ring type exterior fixing rack, by hole loopful (1), cardan universal joint component (2), extending sleeve group
Part (3), hexagon-headed bolt (4) composition, coordinate draw point and Kirschner wire to complete the orthopedic outer fixed operation of long bone of limbs, and feature exists
In：The connected M shapes of each extending sleeve component (3) composition, interlink and mutually restrict, slowly adjusted according to the deformities of bone
The length of extending sleeve component (3) makes the gradual stress of lopsided bone, to normal direction develop, can maintain stablize growth under conditions of by
Step realizes orthopaedic function.Extending sleeve component (3) is by long bolt (5), hex nut (6), anti-back pin (7), M6 swivel nuts (8), adjusting
Spinner (9), casing (10), long nut (11) composition, it is characterised in that：Adjusting spinner (9) by rotation can be complete to upper and lower hole
Ring (1) stretched, angulation, rotation, rotate clockwise and adjust spinner (9) and then extend, rotate counterclockwise, shorten, adjust spinner
(9) it is ten prismatics, ten numbers of 0-9 is carved on each face, is clear that direction of rotation and size, M6 swivel nuts (8)
For M6*1, necessary adjusting can be carried out according to the deformities of bone, cooperation adjusts spinner (9) and uses, and every 360 ° are a screw pitch
Length, representative elongate or shorten 1mm；According to the difference of patient's long bone deformities, the extending sleeve of 3 or more quantity may be selected
Component (3), between extending sleeve component (3) and itself and hole loopful (1) form stable three-legged structure, can adjust different volumes
Number extending sleeve component (3), realize to the flexible of lopsided long bone, angulation, rotation, have reached the purpose of malformation correction.
The utility model has the following advantages compared with prior art：
1 follows tension-stress principle, using the regenerativ biology potential of body, realizes that limbs are orthopedic；
2 minimal invasive techniques, damage is small, and operation does not have to blood transfusion, small to the physiology interference of whole body；
3 can select the connecting rod (extending sleeve component) of unequal number amount according to the different state of an illness and degree of deformity；
4 fix stablies, curative for effect, few intercurrent disease can meet early functional exercise；
5 it is postoperative can routine adjustment holder according to the state of an illness；
6 do not retain implant, are not necessarily to second operation, outpatient service can striking.

Specific implementation mode
With reference to an example, the utility model is described in further detail.
Femur deformity corrective procedure：
First osteotomy, then according to the thickness of patient upper leg and degree of deformity, select appropriate size hole loopful (1) and
The extending sleeve component (3) of unequal number amount, ten thousand section components (2) and hexagon-headed bolt (4) form suitable multi link configuration, cover together
Enter patient's deformity affected part, then capturing position, squeeze into two Cross K-wires near end of thighbone, be fixed on hole loopful (1),
The adjusting spinner (9) for adjusting different numbers keeps hole loopful (1) vertical with the distal femur of deformity, at this time two hole loopfuls (1)
Can be at a degree of angle, being reloaded into two Cross K-wires in distal end later need to also be in hole loopful (1) for the sake of firm
Suitable position draw a small amount of half needle of screw thread, a stable multi link configuration ring type exterior fixing rack is just tentatively installed at this time
It completes.Later stage need to make by the adjusting spinner (9) in the extending sleeve component (3) that adjusts different numbers the femur of deformity at
Angle, displacement, torsion gradually improve until restoring normal line of force of fracture.
Claims (3)
1. the utility model is multi link ring type exterior fixing rack, by hole loopful (1), cardan universal joint component (2), extending sleeve component
