Displacement technique, after replacement of total hip, prosthese failure in vivo is relevant with many factors, such as the design of prosthese, the material of prosthese
Material, the selection of prosthese, prosthese riding position in vivo, POI, prothesis dislocation, prosthesis wear, patient age, mobility
Most important about the placement of wherein acetabular component position Deng factors.
At present when artificial hip joint replacing operation is carried out, need to position acetabular bone angle, typically all according to doctor
Raw experience and visual observation are judging the angle of Acetabular abduction and top rake, but this determination methods error is big, easily causes
Postoperative prosthese is mismatched, and prosthetic loosening is dislocated, and prosthesis wear is big, is reduced the service life of prosthese, is also needed to carry out revision procedure, is increased
Plus pain and the financial burden of patient；And for the trouble with end-stage osteoarthritis, the osteophytosis of the acetabular bone periphery disease such as substantially
Person, acetabular bone angle positioning are inaccurate, more easily cause prothesis dislocation.
Content of the invention
In order to overcome the shortcoming of prior art and deficiency, the invention discloses a kind of positioning for hip replacement is filled
Put, including mounting bracket and connecting rod, one end of the connecting rod is set in outside a connecting rod of the mounting bracket and can be around this
360 degree of rotations of connecting rod, the other end of the connecting rod are provided with the first dial with angle index；First dial is parallel
The first swivel head is provided with, first swivel head is vertically articulated on first dial and can be with respect to first dial
360 degree of rotations；The side of first swivel head is vertically provided with the second dial with angle index；Second dial is put down
Row is provided with the second swivel head, and second swivel head is vertically articulated on second dial and can rotate relative to its 360 degree；
The second swivel head outer end is provided with clamp groove.
Further, the fixed support that the mounting bracket is included offset bracket and is connected with the offset bracket, described
Offset bracket is the parallelogram that the connecting rod that four head and the tail are hinged is surrounded, and the connecting rod is set in the offset bracket top
Connecting rod outside.
Further, the offset bracket is connected with the fixed support by fixed block, and the fixed block upper end is arranged
Outside the connecting rod of the offset bracket, lower end is provided with groove and is fixed on the fixed support.
Further, level meter is embedded with the fixed support.
Further, the fixed support includes high support bar and low support bar, the high support bar by fixed column with
The low support bar connection, the high support bar bottom height are higher than low support bar bottom.
Present configuration is simple, easy to operate, and doctor can adjust support bracket fastened position according to the patient of different body types
With the shape of offset bracket, two rotatable dials are added, allow user that locating bar is fixed on suitable angle, convenient
Acetabular cup is fixed in place.
In order to more fully understand and implement, the present invention is described below in conjunction with the accompanying drawings in detail.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the front view of the present invention.
Fig. 3 is enlarged drawing at A in Fig. 1.
Fig. 4 is connecting rod of the present invention and the first dial schematic diagram.
Fig. 5 is the schematic diagram of the second swivel head of the invention and the second dial.
Specific embodiment
Fig. 1-5 are referred to, a kind of positioner for hip replacement, including mounting bracket and connecting rod 1, the company
One end of extension bar 1 be set in the mounting bracket a connecting rod 61 outer and can around the connecting rod 360 degree rotate, the connecting rod 1
The other end is provided with the first dial 2 with angle index；First dial 2 is arranged with the first swivel head 3 in parallel, and this first
Swivel head 3 is vertically articulated on first dial 2 and can be relative to first dial, 360 degree of rotation；First rotation
3 side is vertically provided with the second dial 4 with angle index；Second dial 4 is arranged with the second swivel head in parallel
5, second swivel head 5 is vertically articulated on second dial 4 and can rotate relative to its 360 degree；Second swivel head 5
Outer end is provided with clamp groove 51.
The fixed support 7 that the mounting bracket is included offset bracket 6 and is connected with the offset bracket 6, the skew
The parallelogram that frame 6 is surrounded for the connecting rod 61 that four head and the tail are hinged, the connecting rod 1 are set in 6 top of the offset bracket
Connecting rod 61 outside.
The offset bracket 6 is connected with the fixed support 7 by fixed block 8, and 8 upper end of the fixed block is set in described
Outside the connecting rod 61 of offset bracket 6, lower end is provided with groove and is fixed on the fixed support 7.
Level meter 71 is embedded with the fixed support 7.
