In the prior art, the fracture fixation effect that internal fixation device encircles before for pelvis is better, yet for there being posterior ring pelvic fracture vertical and that rotation is unstable, effect is still undesirable.Studies have shown that, for the unstable fracture of pelvis that is caused by back ring, fixedly the having very important significance of back line structure, biomechanics Research shows that posterior plate is fixing and can obtain sufficient posterior ring pelvic and stablize.Existing posterior plate system exists wound big, is difficult for placing, and is difficult to shortcomings such as plasticity.The pelvis posterior plate that traditional both wings are fixed is when carrying out the percutaneous Minimally Invasive Surgery, need earlier steel plate to be overturn, steel plate is inserted through subcutaneous from a side otch, after both wings exposed from the both sides otch respectively, the steel plate that overturns again was covered on surface of bone, because both wings fixed angle, very difficult when this steel plate is placed, complex operation, and also steel plate also is not easy and surface of bone pastes clothes.
Those skilled in the art needs to develop a kind of easy and simple to handle urgently, and otch appears easily, and placing easily, ilium way of escape Wicresoft fixture solves the problems referred to above.
The utility model content
The technical problems to be solved in the utility model is relatively poor for the way of escape fixed effect that overcomes ilium fixture in the prior art, and wound is big, be difficult for to place, and is difficult to deficiencies such as plasticity, and a kind of novel ilium way of escape Wicresoft fixture is provided.
This utility model solves above-mentioned technical problem by following technical proposals:
A kind of way of escape Wicresoft ilium fixture comprises connecting rod, first wing steel plate, second wing steel plate, sacroiliac screw, it is characterized in that:
The connecting rod two ends have knuckle, knuckle 100-150 degree, and it is moulding to carry out bending.First wing steel plate and second wing steel plate are identical, one end is U-shaped groove, U-lag links to each other with steel plate by the ball-and-socket type joint that is positioned at the U-lag bottom with steel plate, can hold connecting rod in the U-shaped groove, the U-shaped opening part of U-shaped groove is provided with female thread, but sacrificial vessel has externally threaded hold-down nut to be screwed into, with fixed connecting rod and ball-and-socket joint.
It is characterized in that hold-down nut and hold-down bars offset, be placed with locating stop piece between hold-down bars and the ball-and-socket type joint.
It is characterized in that described first wing steel plate and second wing steel plate arrange a plurality of steel plate hole, are connected with sacroiliac screw at the steel plate hole internal fixation.
It is characterized in that the steel plate hole on described first wing steel plate and second wing steel plate is respectively 2～4.
It is characterized in that the diameter of described hold-down bars is two kinds of 5.5mm, 6.5mm, the groove width of the described first U-shaped groove and the second U-shaped groove is two kinds of 5.5mm and 6.5mm.
Positive progressive effect of the present utility model is: this ilium way of escape Wicresoft fixture structure is simple, uses safety, is convenient to percutaneous and places, and otch appears easily, and it is convenient to place.

The specific embodiment
A kind of way of escape Wicresoft ilium fixture comprises connecting rod 1, first wing steel plate 2, second wing steel plate 3, sacroiliac screw 10 among the figure, it is characterized in that:
The connecting rod two ends have knuckle 9, knuckle 120 degree, and it is moulding to carry out bending.First wing steel plate 2 and second wing steel plate 3 are identical, one end is U-shaped groove 5, U-lag links to each other with first wing steel plate 2 or second wing steel plate 3 by the ball-and-socket type joint 8 that is positioned at U-lag 5 bottoms with steel plate, can hold connecting rod 1 in the U-shaped groove, the U-shaped opening part of U-shaped groove is provided with female thread 4, but sacrificial vessel has externally threaded hold-down nut 6 to be screwed into, with fixed connecting rod 1 and ball-and-socket type joint 8.
It is characterized in that hold-down nut 6 offsets with connecting rod 1, is placed with locating stop piece 7 between connecting rod 1 and the ball-and-socket type joint 8.
It is characterized in that described first wing steel plate and second wing steel plate arrange a plurality of steel plate hole, are connected with sacroiliac screw 10 at the steel plate hole internal fixation.
It is characterized in that the steel plate hole on described first wing steel plate and second wing steel plate is respectively 3.
It is characterized in that the diameter of described hold-down bars is 6.5mm, the groove width of the described first U-shaped groove and the second U-shaped groove is 6.5mm.
