Abstract

The invention provides an external fixation support used for hip joint fracture fixation. The external fixation support used for hip joint fracture fixation comprises four fixation needles, four cardan joints, two connecting rods and a tight fixation structure, wherein the fixation needles are arranged on the cardan joints, the connecting rods are arranged in through holes of the cardan joints, each connecting rod is provided with two cardan joints, and the two connecting rods are parallel; the tight fixation structure is connected to the connecting rods or connected to the fixation needles, and comprises two jagged tightening rods which are arranged in a square cavity, a rotary plate corresponding to the jagged structure is arranged on the portion, between the two tightening rods, in the square cavity, the rotary plate is provided with a rotary handle on the upper portion of the square cavity, the aim that the lengths of the tightening structures are adjusted is achieved by rotating the rotary handle on the upper portion of the rotary plate, and then the aim that the distance of the two connecting rods on the two sides is adjusted is achieved; the square cavity is provided with a rotary plate locking structure. In the hip joint fracture fixation process, only one person is needed, adjustment of the external fixation support can be easily achieved, and the operation is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of orthopedic instruments, in particular to a medical instrument for fracture fixation, in particular to an external fixation bracket for hip joint fracture fixation. Background technique [0002] Pelvic fractures are mostly high-energy trauma, often associated with blood vessel, nerve, and visceral injuries. Pelvic fractures account for 1-2% of systemic fractures, while the mortality rate of unstable pelvic fractures combined with massive bleeding is between 20-50%. It has been reported in the literature that the early application of external fixation in trauma can reduce the mortality rate during recovery from 22% to 8%. However, the external fixator for pelvic reduction currently used clinically requires two doctors to push and pull to the appropriate position from both sides, and the third doctor fixes and adjusts. The operation requires a lot of manpower, and the fine-tuning effect of the external fixat...
