Description
Technical Field
The utility model belongs to the technical field of medical instrument and specifically relates to a rib hook for spinal surgery.
Background
The spine is the pillar of the body, is located in the middle of the back, with the upper end connected to the skull and the lower end reaching the tip of the coccyx. The spine is divided into five sections of neck, chest, waist, sacrum and tail, the upper part is long and can move, and the spine is similar to a bracket and is hung on the chest wall and the abdominal wall; the lower part is short and is fixed. The weight of the body and the shocks received thereby are transmitted to the lower limbs. The spine is composed of vertebrae and intervertebral discs, and is a relatively flexible and mobile structure. The shape of the spine can vary considerably with the kinematic loading of the body.
The front of the spine is formed by the accumulation of vertebral bodies, the front of the spine is adjacent to the viscera of the chest and abdomen, not only protects the viscera, but also protects the nerves and blood vessels of the viscera, and only a thin loose tissue is separated between the nerves and the blood vessels. When the vertebral body is damaged, pus can be gathered behind the pharynx on the neck, or can descend to the subclavian fossa along the neck, or can also descend to the armpit along the brachial plexus; on the chest, it can extend along intercostal nerves to the chest wall, and can also reach the mediastinum; the waist can descend along the aponeurosis of the psoas major to form the aponeurosis of the psoas major, which can flow to the lower part of the groin and can also bypass the lesser trochanter of the femur to the hip.
The posterior aspect of the spine consists of the vertebral arch, lamina, transverse processes and spinous processes of each vertebra. The superficial surfaces of the two parts are only covered with muscles, and are relatively close to the body surface, so that the user can easily touch the muscles. Lesions in the posterior part of the spine tend to puncture the skin.
The spinal canal is arranged between the front and back surfaces of the spine, the spinal cord is hidden, and the peripheral bony structures such as vertebral bodies, vertebral arches and vertebral plates can cause spinal cord compression disease when entering the spinal canal due to fracture or other pathological changes, and even paraplegia can be caused by small bleeding and granulation tissues.
Spondylopathy is a common symptom caused by changes of bones, intervertebral discs, muscles and ligaments of the spine and stimulation of spinal cords and spinal nerves. The disease is mostly manifested as aching pain of neck and shoulder, headache, vertigo, aching pain of lumbosacral part, even pain of lower limbs caused by involvement, unable to stand up and the like, and severe patients may cause paralysis and have adverse effect on the life quality of patients.
