Abstract
The invention discloses a locating assembly for parallel needle penetration and angle rotation of the femoral osteotomy of hip dislocation. The locating assembly comprises a steel plate arranged on the outer side of the proximal femur, a drilling template arranged over the proximal femur, a rotation angle locating instrument for aligning two holes of each fixing base of far side and near side assemblies and two holes of the far side and two holes of the near side of the femoral osteotomy, and a dial fixed to the femur and used for locating the rotation angle locating instrument. The locating assembly has the advantages that the locating instrument is used for locating of needle penetration and angle rotation, and locating is accurate.
Description
Technical field
The invention belongs to technical field of medical equipment, it is related to the parallel anglec of rotation positioning component of threading a needle of hip dislocation femur osteotomy
And localization method.
Background technology
Under developmental dislocation of hip joint femoral trochanter, rotation is shortened in osteotomy, and for convenience of estimating the anglec of rotation, routine exists
Before osteotomy, in osteotomy distance end, same plane pierces two pieces of parallel Kirschner wires as witness marker, and after shortening osteotomy, outward turning is remote
End, to correct excessive top rake, determines the angle of rotation according to angle between two pieces of Kirschner wires.But in clinical manipulation, put down
Row is threaded a needle and the anglec of rotation all leans on patient's range estimation and experience, very inaccurately.Therefore it is badly in need of a kind of parallel thread a needle and the anglec of rotation
Location instrument, to make operation technique accurately and unitized.
Content of the invention
It is an object of the invention to provide the parallel anglec of rotation positioning component of threading a needle of hip dislocation femur osteotomy, solve existing
Dislocation of hip joint femur osteotomy is threaded a needle and the anglec of rotation all leans on patient's range estimation and experience, highly inaccurate problem.
It is a further object to provide being applied to the localization method of this kind of assembly.
The technical solution adopted in the present invention is:
Including the steel plate being positioned over outside near end of thighbone；
It is positioned over the bore template directly near end of thighbone；
The anglec of rotation position finder that assembly each firm banking holes in far and near side is alignd with each holes in femur osteotomy distance side；
It is fixed together with femur, for the graduated disc of anglec of rotation position finder positioning.
Further, described graduated disc is made up of support and rule.
The localization method of the parallel anglec of rotation positioning component of threading a needle of hip dislocation femur osteotomy, follows the steps below:
Step 1: first steel plate is positioned over outside near end of thighbone, steel plate central authorities just to femur first time osteotomy line, by steel plate
Nearside half and femur are fixed together.The support of graduated disc is fixed by screws on femur, bore template is positioned over
Directly near end of thighbone, bore template central authorities just to femur first time osteotomy line, respectively at first time osteotomy line nearside and second
The corresponding position in secondary osteotomy line distally drills through monolayer cortical bone above femur by the adjacent holes of bore template, you can guarantee to be bored
Four bone hole point-blank；
Step 2: with line according to row first time and second osteotomy, the distance between the one or two osteotomy line is what needs shortened
Femur length.Each for anglec of rotation position finder distance side assembly firm banking holes is alignd with each holes in femur osteotomy distance side,
It is screwed into 4 pieces of diameter 2.5mm screws to fix, do not rotate 0 degree of position just to distally assembly angle bar for the front nearside assembly pointer.
Step 3: outward turning femur osteotomy far-end, when nearside assembly pointer just to distally assembly angle bar corresponding scale
When the angle of chi is the angle needing rotation, maintained behind this position good with Calco pincers, with screw by steel plate distally half and femur
Osteotomy distal end portion is fixed together, i.e. end of operation.
The invention has the beneficial effects as follows using position finder to threading a needle and the anglec of rotation positions, registration.

Fig. 3 is bore template schematic diagram of the present invention.
In figure, 1. steel plate, 2. bore template, 3. anglec of rotation position finder, 4. graduated disc, 5. support, 6. rule.
Specific embodiment
The present invention is described in detail with reference to the accompanying drawings and detailed description.
The technical solution adopted in the present invention as shown in Figure 1 to Figure 3, including the steel plate 1 being positioned over outside near end of thighbone；Put
It is placed in the bore template 2 directly near end of thighbone；The each firm banking holes of far and near side assembly and each holes in femur osteotomy distance side
The anglec of rotation position finder 3 of alignment；It is fixed together with femur, for the graduated disc 4 of anglec of rotation position finder 3 positioning.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, follows the steps below:
Step 1: first steel plate 1 is positioned over outside near end of thighbone, steel plate 1 central authorities just to femur first time osteotomy line, by steel
Plate 1 nearside half is fixed together with femur.The support 5 of graduated disc 4 is fixed by screws on femur, by bore template 2
Be positioned over directly near end of thighbone, bore template 2 central authorities just to femur first time osteotomy line, respectively at first time osteotomy line nearside
Corresponding position drills through monolayer cortical bone above femur by the adjacent holes of bore template 2 with second osteotomy line distally, you can
Guarantee bored four bone hole point-blank；
Step 2: with line according to row first time and second osteotomy, the distance between the one or two osteotomy line is what needs shortened
Femur length.Each for anglec of rotation position finder 3 far and near side assembly firm banking holes is alignd with each holes in femur osteotomy distance side,
It is screwed into 4 pieces of diameter 2.5mm screws to fix, do not rotate 0 degree of position just to distally assembly angle bar for the front nearside assembly pointer.
Step 3: outward turning femur osteotomy far-end, when nearside assembly pointer 3 just to distally assembly angle bar corresponding quarter
When the angle of degree chi 6 is the angle needing rotation, maintained behind this position good with Calco pincers, with screw by steel plate 1 distally half with
Femur osteotomy distal end portion is fixed together, i.e. end of operation.
, using position finder to threading a needle and the anglec of rotation positions, registration, invention components structure is simple for the present invention,
Low cost, is suitable to large-scale promotion.The above is only the better embodiment to the present invention, not the present invention is appointed
What pro forma restriction, every technical spirit according to the present invention, to any simple modification made for any of the above embodiments, is equal to become
Change and modify, belong in the range of technical solution of the present invention.
