Abstract
The utility model discloses the parallel anglec of rotation positioning component of threading a needle of hip dislocation femur osteotomy, comprise the steel plate that is positioned near end of thighbone outside; Be positioned over the bore template directly near end of thighbone; The anglec of rotation position finder aliging with each two holes of the far and near side of femur osteotomy in the far and near each firm banking of side assembly two holes; Be fixed together with femur, for the graduated disc of anglec of rotation position finder location.The beneficial effects of the utility model are to use position finder to position with the anglec of rotation threading a needle, registration.
Description
Technical field
This utility model belongs to armarium technical field, relates to the parallel anglec of rotation positioning component of threading a needle of hip dislocation femur osteotomy.
Background technology
Under developmental dislocation of hip joint femoral trochanter, rotation is shortened in osteotomy, estimate for convenience the anglec of rotation, routine pierces two pieces of parallel Kirschner wires as witness marker in the far and near end of osteotomy same plane before osteotomy, shorten after osteotomy, outward turning far-end, to correct excessive top rake, is determined the angle of rotation according to angle between two pieces of Kirschner wires.But in clinical manipulation, parallel threading a needle all leaned on patient's range estimation and experience, very inaccuracy with the anglec of rotation.Therefore be badly in need of a kind of parallel threading a needle and the location instrument of the anglec of rotation, make operation technique accurately and unitized.
Utility model content
The purpose of this utility model is to provide hip dislocation femur osteotomy the parallel anglec of rotation positioning component of threading a needle, and has solved existing threading a needle and all lean on patient's range estimation and experience, very coarse problem with the anglec of rotation in dislocation of hip joint femur osteotomy.
The technical scheme that this utility model adopts is:
Comprise the steel plate that is positioned near end of thighbone outside;
Be positioned over the bore template directly near end of thighbone;
The anglec of rotation position finder aliging with each two holes of the far and near side of femur osteotomy in the far and near each firm banking of side assembly two holes;
Be fixed together with femur, for the graduated disc of anglec of rotation position finder location.
Further, described graduated disc is made up of support and rule.
The beneficial effects of the utility model are to use position finder to position with the anglec of rotation threading a needle, registration.

In figure, 1. steel plate, 2. bore template, 3. anglec of rotation position finder, 4. graduated disc, 5. support, 6. rule.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is elaborated.
The technical scheme that this utility model adopts as shown in Figure 1 to Figure 3, comprises the steel plate 1 that is positioned near end of thighbone outside; Be positioned over the bore template 2 directly near end of thighbone; The anglec of rotation position finder 3 aliging with each two holes of the far and near side of femur osteotomy in the far and near each firm banking of side assembly two holes; Be fixed together with femur, the graduated disc 4 of locating for anglec of rotation position finder 3.Described graduated disc 4 is made up of support 5 and rule 6.
The localization method of the parallel anglec of rotation positioning component of threading a needle of hip dislocation femur osteotomy, carries out according to following steps:
Step 1: first steel plate 1 is positioned near end of thighbone outside, steel plate 1 central authorities, just to femur osteotomy line for the first time, are fixed together steel plate 1 nearside half and femur.The support of graduated disc 45 is fixed by screws on femur, bore template 2 is positioned over directly near end of thighbone, bore template 2 central authorities are just to femur osteotomy line for the first time, respectively at osteotomy line nearside for the first time and for the second time corresponding position, osteotomy line distally by the bore template 2 saturating femur of adjacent two hole drill top monolayer cortical bone, can guarantee four bored bone holes point-blank;
Step 2: according to for the first time and for the second time osteotomy of row, the distance between the one or two osteotomy line is needs the femur length that shortens with line.Alignd with each two holes of the far and near side of femur osteotomy in each far and near anglec of rotation position finder 3 side assembly firm banking two holes, be screwed into 4 pieces of diameter 2.5mm screws and fix, not the just 0 degree position to distally assembly angle bar of nearside assembly pointer before rotation.
Step 3: outward turning femur osteotomy far-end, in the time that nearside assembly pointer 3 is just to the angle of rule 6 corresponding to distally assembly angle bar the angle that needs rotation, clamp and maintained behind this position with cock, steel plate 1 distally half is fixed together with femur osteotomy distal end portion with screw, i.e. end of operation.
This utility model uses position finder to position with the anglec of rotation threading a needle, registration, and this utility model modular construction is simple, and cost is low, is suitable for large-scale promotion.The above is only to preferred embodiments of the present utility model, not this utility model is done to any pro forma restriction, every foundation technical spirit of the present utility model is to any simple modification made for any of the above embodiments, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
