Description
Technical field
This reality newly relates to the external fixation used for orthopedics tool in a kind of clinical medicine, particularly relates to a kind of for fracture fixation and the three-dimensional fixed support of malformation correction and the skeleton external fixer with this support.
Background technology
The bone that fracture and many reasons cause is not healed, bone delay in healing and skeleton deformity seriously threaten the health of the mankind and affect living standard and the quality of life of disability crowd, Orthopaedic external fixator treatment technology is exactly that the far and near two ends percutaneous at fracture or deformity respectively penetrates spicule, the afterbody of spicule is stayed external, with needle stand, spicule and exterior fixation bracket are connected and fixation the most again, with to fracture and lopsided external stability and a kind for the treatment of technology of adjustment, it is advantageous that, operation Wicresoft, little or non-incision, neither destroy local blood circulation and be provided that again stable bone is fixed, here it is from mechanics and in terms of biology two be fracture healing and deformity rectification create strong condition.
What traditional treatment fracture and the Orthopaedic external fixator of malformation correction were roughly divided into from product structure that monolateral Combined type external fixed support, multilateral combinations formula exterior fixation bracket and the current China of the most circular combined exterior fixation bracket of circular combined exterior fixation bracket three major types continues to use is the ILIZAROV ring external fixation support system product of former Soviet Union's invention mostly.ILIZAROV ring external fixation support technology is a FA technology, famous with " Wicresoft, all-round ", although this technology can complete from the simplest to the most complicated various fracture fixations and malformation correction, but the problem of ring external fixation support maximum is operation and uses sufficiently complex, the number of parts of product is many, installation anomaly association is loaded down with trivial details, and general doctor is difficult to grasp.The complexity of mounting technique and technology of threading a needle all leverages the promotion and application of this technology, the especially malformation correction to the space angle of skeleton, ILIZAROV ring external fixation support technology needs ring external fixation support to do in many planes repeatedly to adjust, and slightly all operation to be allowed to be difficult to reach promising result the most failed for mistake.nullAdditionally，Current monolateral and polygon exterior fixation bracket technology and ILIZAROV ring external fixation support are all a kind of non-experiential therapies accurately，That is，Operative doctor in operation be all by feat of self experience to fracture and deformity carry out rough para-position，Recover fracture and the anatomical position of deformity by image documentation equipment simultaneously，There is deviation owing to art being measured more，Condition imperfection plus doctor hospital of a lot of basic units，The precision of equipment and suffer from position and break forth the reasons such as the definition of X sheet is the most less desirable，Greatly have impact on the accuracy that perioperatively is measured，Also operation is caused to be unable to reach accurate para-position，The deformity that complicated part combination and adjustment more make operative doctor be difficult to angle and the displacement remaining the skeleton caused in operation because of a variety of causes is modified and final accurate contraposition，These performances all limiting exterior fixation bracket technical advantage and application.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, this utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of three-dimensional fixed support 10, including upper ring 100, lower ring 200 and the upper ring 100 of several connections and the support bar 300 of lower ring 200；The two ends of described support bar 300 are both provided with universal joint 310, and two universal joints 310 that described support bar 300 two ends are arranged are connected with upper ring 100 and lower ring 200 respectively；Be provided with on described upper ring 100 several for install pin folder the first installing hole 110, on described lower ring 200 be provided with several for install pin folder the second installing hole 220.Support bar 300 includes support bar 302 that bore is big and the little support bar 304 of bore, the support bar 302 that described bore is big is hollow bushing, the support bar 304 that described bore is little is socketed in the big support bar of bore 302, and can do stretching motion in the support bar 302 that bore is big.The junction of support bar 302 that bore is big and the little support bar 304 of bore is provided with adjusting means 320, described adjusting means 320 can be rotated both clockwise and counterclockwise, this adjusting means 320 clockwise or counterclockwise time, the support bar 304 that described bore is little can extend or shorten.
As in figure 2 it is shown, described adjusting means 320 is every rotates 180 ° counterclockwise, described support bar 300 shortens 0.5mm；Described adjusting means 320 often turns clockwise 180 °, and described support bar 300 extends 0.5mm.It is additionally provided with scale 352 on the support bar 302 that bore is big, the support bar 304 that described bore is little is provided with the mark 354 for reference mark.
As it is shown in figure 1, described support bar 300 quantity is 6, the most V-shaped mitered of support bar 300 is on upper ring 100 and lower ring 200.As it is shown on figure 3, be additionally provided with the numbered snap ring of labelling 350 on described support bar 300.As shown in Figure 4, upper ring 100 and/or generally circular in shape, the c-type of lower ring 200 and U-shaped in one.
As it is shown in figure 1, described first installing hole 110 is arranged on the side of ring 100, described second installing hole 220 is arranged on the side of lower ring 200.During use, the universal joint 310 at support bar 300 two ends grub screw is locked in the first installing hole 110 and the second installing hole 220, simple and convenient, it is possible to reduce operating time.
As it is shown in figure 5, this utility model additionally provides a kind of skeleton external fixer, the pin folder 40 that including fixed support, is arranged on fixed support and be arranged on the spicule 50 on pin folder, its fixed support is above-mentioned three-dimensional fixed support.
With reference to Fig. 1-Fig. 5, when the skeleton external fixer of the novel offer of this reality uses, first it is sequentially sleeved in snap ring 350 according to number order counterclockwise on support bar 300 to show difference and inputs used to be supplied to the parameter of computer software.Upper ring 100 and lower ring 200 are fixedly connected with skeleton 60 are integrated by pin folders 40 and spicule 50, depending on the specification of spicule 40 and quantity are according to clinical concrete needs, with Wicresoft with firmly as principle；Connected by support bar 300 between upper ring 100 and lower ring 200.By adjusting the length of every support bar 300 respectively, fracture fixation or deformity are dissected para-position, and reaches the most fixing, thus the three-dimensional solid realizing skeleton resets, adjusts and stablize fixing.
A kind of three-dimensional framework support that this utility model provides and have the skeleton external fixer of this support have simple to operate effectively, surgical effect is the most adjustable, degree of accuracy reliable, and traumatic fracture, bone does not connect, nonunion and bone malformation rectification etc. effectively can be treated.
Above disclosed it is only this utility model preferred embodiment, certainly can not limit the interest field of this utility model, the equivalent variations therefore made according to this utility model claim with this, still belong to the scope that this utility model is contained.
