Iliac fixation device

Abstract

The invention relates to an ilium fixing device which comprises a connecting rod. The ilium fixing device is characterized in that the ilium fixing device is provided with a first U-shaped groove, a second U-shaped groove, a first wing steel plate arranged on the first U-shaped groove, and a second wing steel plate arranged on the second U-shaped groove, wherein the first U-shaped groove and the second U-shaped groove are respectively and symmetrically arranged at two ends of the connecting rod by ball socket-shaped joints arranged at two ends of the connecting rod, and the first wing steel plate and the second wing steel plate are fixed by fixed nuts. The ilium fixing device is characterized in that U-shaped top ends of the first U-shaped groove and the second U-shaped groove are respectively provided with a small through hole, the connecting rod penetrates through the small through holes, the ball socket-shaped joints are arranged at the inner sides of the U-shaped top ends of the U-shaped grooves, the first wing steel plate and the second wing steel plate are respectively provided with a fixed bar, the fixed bars are respectively inserted into the first U-shaped groove and the second U-shaped groove, the fixed bars are arranged in the middle of the U-shaped grooves, and U-shaped openings of the first U-shaped groove and the second U-shaped groove are respectively provided with an internal screw thread. The ilium fixing device has the beneficial effects that the ilium fixing device is simple in structure, safe to use, and convenient to percutaneously place, a cut is easy to appear, and the ilium fixing device is convenient to place.

Description

technical field [0001] The invention relates to a medical device, in particular to an ilium fixation device suitable for percutaneous internal fixation of iliac plate screws. Background technique [0002] With the development of medical technology, all kinds of medical auxiliary equipment have emerged as the times require. In surgery, fixation devices are often required to fix bones. The morbidity and mortality of unstable pelvic fractures are high. To address this medical problem, various internal fixation devices have been developed accordingly. [0003] In the prior art, internal fixation devices have a good fixation effect on fractures of the anterior pelvic ring, but the effect is not ideal for fractures of the posterior pelvic ring with vertical and rotational instability. Studies have shown that for unstable pelvic fractures caused by the posterior ring, the fixation of the posterior structure is very important. Biomechanical studies have shown that the posterior pl...
