Description
Technical Field
The utility model relates to the technical field of medical auxiliary equipment, in particular to an external fixation support for assisting the correction of limb deformity.
Background
The external fixing bracket is applied to clinic, and makes limb extension and orthopedic technology have epoch-making leap. With the continuous deepening of basic research and the expansion of the range of clinical application, the external stent fixing technology is widely applied to the extension and functional reconstruction of limbs, and provides an effective treatment means for bone defects, osteomyelitis, complicated limb deformity, unequal limb length and other orthopedic difficult and complicated diseases.
Usually, the fixing support is drilled into the fracture two ends or the far and near ends of the bone joint deformity osteotomy orthopedic by using an external fixing needle, and then the needle penetrating into the fracture is fixed on the external fixing support in the skin, and has the following functions:
1) can keep the fracture end well reset;
2) the two ends of the backbone can be retracted to prolong the limbs;
3) the compression technology can be utilized to promote fracture healing;
4) can correct early angular and rotational deformities, such as old fracture.
After external fixation of fracture, limb deformity caused by various reasons is cut, after the external fixation of orthopedics, the orthopedics is often unsatisfied, and in the process of correcting and fixing, the recurrent deformity needs to be corrected due to the recurrent deformity caused by secondary deformity of limb growth, deformation of external fixing frame or other factors and the like. The conditions of the bone joint varus and the internal and external rotation deformity relapse after the external fixation operation do not have an external fixation bracket which well solves the problems at present.
SUMMERY OF THE UTILITY MODEL
In order to overcome the above disadvantages of the prior art, the present invention provides an external fixation frame for assisting the correction of deformities of limbs.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an orthopedic outer fixed bolster that assists correction of limbs deformity of fracture, includes guide bracket and guide block, wherein:
the guide bracket comprises at least 2 guide structures, a side face of the guide structure is fixed to the guide block through the positioning columns and the positioning holes respectively, the guide structure is attached to the guide block to form a guide hole, a guide steel nail is fixed in the guide hole, the guide structure comprises a bone cutting near-end guide structure and a bone cutting far-end guide structure, the bone cutting near-end guide structure is arranged on a first fixing plate of the guide bracket, and the bone cutting far-end guide structure is arranged on a second fixing plate of the guide bracket.
As a further improvement of the utility model: the side face orientation of the first fixing plate and the side face orientation of the second fixing plate form different spatial positions and included angles according to calculation.
As a further improvement of the utility model: the first fixing plate and the second fixing plate are fixedly connected through a twisted connecting plate.
As a further improvement of the utility model: one side of the guide structure is provided with at least two transverse first semicircular guide grooves, and at least four first positioning holes are formed in the inner side surface of the guide structure in a penetrating mode.
As a further improvement of the utility model: and at least two second semicircular guide grooves matched with the first semicircular guide grooves are formed in one side surface of the guide block, and at least four second positioning holes are formed in the inner side surface of the guide block in a penetrating mode.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses it is equipped with osteotomy near-end guide structure, osteotomy far-end guide structure respectively to cut the orthopedic near-end of bone according to limbs deformity, and cuts bone far, near-end guide structure and form corresponding relative spatial position and different contained angles according to calculating, can effectively assist the orthopedic fixed that has the condition such as the limbs internal valgus, inside and outside rotation deformity.

Fig. 2 is an exploded view of the present invention.
Fig. 3 is an exploded view of the present invention.
Detailed Description
The invention will now be further described with reference to the accompanying drawings, in which:
referring to fig. 1, an external fixation brace for orthopedic fracture comprises a guide brace 1 and a guide block 2, wherein: the guide support 1 comprises at least 2 guide structures, the guide block is fixed on one side face of each guide structure through the positioning columns and the positioning holes 11, the guide structures and the guide blocks are attached to form guide holes 3, and guide steel nails are fixed in the guide holes 3. And the positioning column is provided with a bolt structure, and the guide block is locked in the guide structure through the bolt structure.
Referring to fig. 2, at least two transverse semicircular guide grooves 12 are formed in one side surface of the guide structure, and at least four first positioning holes 11 are formed through the inner side surface; at least one second semicircular guide groove 21 matched with the first semicircular guide groove is formed in one side face of the guide block 2, and at least four second positioning holes 22 penetrate through the inner side face. And the bolt structure on the positioning column is locked, so that the first semicircular guide groove and the second semicircular guide groove form a guide hole, and the guide steel nail is fixed through the friction force of the inner groove surface of the semicircular guide groove.
Referring to fig. 3, the guiding structure includes an osteotomy proximal guiding structure 4 and an osteotomy distal guiding structure 5, and the osteotomy proximal guiding structure 4 and the osteotomy guiding structure 5 are respectively disposed on the first fixing plate 13 and the second fixing plate of the guiding bracket 1. The side face orientation of the first fixing plate 13 forms an included angle with the side face orientation of the second fixing plate 14, so that the osteotomy distal end guiding structure can fix the outward-turning deformed talus to meet the orthopedic fixation.
The first fixing plate 13 and the second fixing plate 14 are fixedly connected through a twisted connecting plate 15. Cut bone guide structure 5 and talus guide structure 6's the outside and be equipped with two strengthening ribs 7, fix the fastness that has effectively strengthened external fixation through the strengthening rib.
In conclusion, after the ordinary skilled in the art reads the document of the present invention, according to the present invention, the technical solution and technical concept of the present invention do not need creative mental labor to make other various corresponding transformation schemes, which all belong to the protection scope of the present invention.
