Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a traction device after lumbar spine surgery. Background technique [0002] At present, traction is a method often used to treat fractures, postoperative and other orthopedic diseases, and it is divided into bone traction, pelvic traction, skin traction, etc. according to different parts of the human body. Shoulder disc herniation, lumbar hyperosteogeny, and spinal stenosis are common diseases of middle-aged and elderly people and sedentary office workers. It directly affects the sciatic nerve of the patient. In mild cases, the pain in the waist and legs cannot stand upright. The traction is through external force or the human body itself. The gravity will widen the gap between the cervical vertebrae through traction, and at the same time limit the activity of the cervical spine, which is conducive to the reduction of tissue congestion and edema, and is conducive to the r...

Problems solved by technology

Increase the height of the intervertebral space and the intervertebral foramen, restore the normal arrangement of the vertebral bodies, relieve the stimulation and compression of the nerve roots, spinal cord and sympathetic nerves, and stretch the vertebral arteries twisted between the transverse foramen. The retractors are mainly horizontal retractors, which are large in size and require a fixed place. They need to be supervised by a special person. The operation is cumbersome and not easy to carry.
