Problems solved by technology

[0003] In the above three methods, the internal fixation devices are divided into two parts, one part is in front of the pelvis, and the other part is in the pelvis, and the two parts are separated, so that the overall stability is not enough; the standards of various devices are different, and the connection is inconvenient; at the same time , the existing fracture fixation methods cannot easily adjust the pressure between the instrument and the pelvis

Embodiment 1

[0037] Such as Figure 1 ~ Figure 3 As shown, a pelvic internal bracket fixation system according to the present invention includes a curved rod 1, two pelvic screws 2, and a connecting assembly 3. The curved rod 1 is used to be placed under the abdomen, and the pelvic screw 2 is used to pass through the pelvis. ilium. One ends of the two pelvic screws 2 are connected to the curved rod 1, and the other ends of the two pelvic screws 2 are respectively connected to the two ends of the connecting assembly 3, that is to say, the two pelvic screws 2, the curved rod 1 and the connection The components 3 form a closed ring, and the ring structure makes the overall structure more stable. At the same time, the length of the connecting component 3 can be stretched. When the connecting component 3 is stretched, the two pelvic screws 2 can be stretched in the opposite direction; when the connecting component 3 is shortened, the two pelvic screws 2 can be tightened in the same direction t...

Embodiment 2

[0047] Such as Figure 4 As shown, the difference between embodiment 2 and embodiment 1 is that the present invention also includes an ilium connecting rod 5, which is sleeved on the pelvic screw 2, and the ilium connecting rod 5 can be connected and fixed with the lumbar spine.

[0048] For other structures of the pelvic intrapelvic bracket fixing system described in the present invention, refer to the prior art.

Abstract

The invention discloses a pelvis inner stent fixing system. The pelvis inner stent fixing system comprises two pelvis screws and a bent stick which is placed on the abdomen of a patient in a hypodermic manner, and further comprises a connecting assembly; one ends of the two pelvis screws are separately connected with the bent stick; the length of the connecting assembly is changeable; and the other ends of the two pelvis screws are separately connected with two ends of the connecting assembly correspondingly. The two pelvis screws, the bent stick and the connecting assembly form a closed ring,and by the ring-shaped structure, the overall structure is stable; and meanwhile, the length of the connecting assembly is changeable, the two pelvis screws can be expanded or tightened, a function of regulating the pressure of a pelvis in the left-right direction is fulfilled, and pressure adjusting operation is simple.

Description

technical field [0001] The invention belongs to the technical field of medical auxiliary equipment, and in particular relates to a pelvic inner bracket fixing system. Background technique [0002] Pelvic fracture is a type of serious orthopedic injury. Common surgical fixation methods include anterior pelvic ring fixation, posterior pelvic ring fixation, and channel screw fixation. The fixation methods of the anterior pelvic ring mainly include external fixation bracket, plate screw fixation, percutaneous screw-rod system fixation and simple screw fixation; the posterior pelvic fixation includes trans-ilium plate fixation, ilium rod fixation, trans-ilium screw-rod fixation and adjustable Bone plate; channel screw fixation Primary spine pelvic screw-rod system fixation, which is suitable for cases where the pelvis and lumbar spine are fixed together. [0003] In the above three methods, the internal fixation devices are divided into two parts, one part is in front of the pel...
