Specific embodiment
As shown in Figure 1 to Figure 3, structure of the invention includes 1, two group of pelvis prelocalization component of c-type connection frame and two groups of pelvises
Positioning component afterwards, c-type connection frame 1 are the external connection frame that opening is trapped among loins backwards, can be made of carbon fibre material, be rigid
Property rodlike or tubular structure, light-weight and intensity is big, and shape and human lumbar half interval contour are adapted, and can have different big small-sized
Number.
Pelvis prelocalization component includes that preceding fixinig plate 2, tension needle 3 and front connecting piece 4, preceding fixinig plate 2 are fixed by screw
At pubic symphysis, tension needle 3 is screw-rod structure of the bottom end with bulb, tenses the bottom end of needle and the top spherical surface of preceding fixinig plate 2
Pair connection tenses needle 3 and is freely rotatable.One end of front connecting piece 4 and tension 3 top bolt of needle, the other end of front connecting piece 4
It is positioned at the corresponding position of c-type connection frame 1, the settable screw hole in the end of front connecting piece 4 is solid by screw and c-type connection frame 1
Fixed connection, may also set up location hook, is directly hooked on c-type connection frame 1.
Positioning component includes rear fixinig plate 5, positioning column 6 and rear connecting piece 7 after pelvis, and rear fixinig plate 5 is fixed by screw
At the pelvis ilium ridge of respective side, positioning column 6 can be structure as a whole with rear fixinig plate 7, and the top of bottom end and rear fixinig plate 5 is solid
Fixed to be connected, one end and the positioning column 6 of rear connecting piece 7 are fixedly attached, and the other end of rear connecting piece 7 is fixedly connected on C by screw
The corresponding position of type connection frame 1.
The present invention is in application, in each self-positioning one group of pelvis prelocalization component in the two sides of pelvis pubic symphysis, in pelvis
Each component is connected as one, passes through by positioning component, c-type connection frame 1 after each self-positioning one group of pelvis at the ilium ridge of two rear side sides
Co-acting force between each component tenses pelvis to centre, so that c-type connection frame 1 is automatically positioned at patient's loins, is not necessarily to
Instrument is auxiliarily fixed in other, more convenient.
In the course of surgery, to reset the pelvis extended out precisely, the present invention is by auxiliary after auxiliary member before pelvis and pelvis
Assistant piece is operated.
