Technical Field

[0001] The utility model relates to the field of pelvic fracture fixation, and specifically relates to a pelvic fracture fixation device for emergency departments. Background Art

[0002] The pelvis is a ring structure and has the function of supporting the spine. When the pelvis is severely impacted, it is easy to cause damage to the bony structure of the pelvis, resulting in pelvic fractures. Pelvic fractures are mainly fixed by external fixation and internal fixation methods. Currently, the external fixation method usually uses a fixing band that wraps upward from the lower side of the buttocks and then is tied and fixed on the upper side of the buttocks.
