Description

Technical Field

[0001] The utility model belongs to the field of correction instruments, in particular to an adjustable back extension type external fixator. Background Art

[0002] Traditional Chinese medicine hyperextension reduction plays an important role in the treatment of vertebral compression fractures. Hyperextension reduction treatment of spinal compression fractures is to hyperextend the spine under traction to form an arch bridge shape. The wrinkled anterior longitudinal ligament in front of the fractured vertebra is stretched, increasing the tension of the anterior longitudinal ligament and the fiber ring of the intervertebral disc. It can effectively reduce fracture dislocation and correct the kyphosis angle, thereby restoring the physiological curvature of the spine and the height of the vertebral body, and correcting the kyphosis deformity. The spinal orthopedic fixator is an auxiliary medical device that replaces manual reduction. It is used to support and correct the spine, help treat or manage spinal-related problems, and help correct posture, relieve pain, stabilize the spine or promote natural healing by providing support, restricting movement or changing spinal posture.

[0003] According to Chinese patent application No.: 202321013685.4, a spinal orthopedic external fixator is disclosed, which belongs to the field of medical device technology. The spinal orthopedic external fixator includes a head fixation device and a pelvic fixation device. The head fixation device includes a head ring for fixing to the patient's head; the pelvic fixation device includes a straight connecting tube located on both sides of the patient for fixing to the patient's pelvis and an arc-shaped connecting tube located in front of the patient and connected to the straight connecting tube; an adjustable length adjustment rod is provided between the head ring and the arc-shaped connecting tube, the upper end of the adjustment rod is connected to the head ring, and the lower end is connected to the arc-shaped connecting tube through an angle-adjustable rod-rod clamp;

[0004] The comparative case effectively solves the problem of unsatisfactory correction effect of spinal orthopedic external fixators in the prior art, and has the advantages of good correction effect and short recovery period. However, this type of spinal orthopedic external fixator can only perform conventional spinal reduction and cannot adapt to patients with kyphosis, thereby reducing the use effect of the spinal orthopedic external fixator.
