Description

A spinal osteotomy reduction guide device

technical field

The invention relates to the technical field of medical devices, in particular to a spinal osteotomy reduction guide device.

Background technique

The vertebra is a general term for vertebrae. The vertebra is composed of the vertebral body, the vertebral arch, the spinal spine, the transverse process of the vertebral body, the anterior articular process and the posterior articular process. The spine is the spine of the human body. It is formed by connecting 24 vertebrae, 1 sacrum and 1 coccyx. It is the main bone structure for the support and activities of the upper body of the human body. The uppermost part is the cervical vertebra that connects with the head, and the lowermost part is the coccyx. The spinous processes behind the vertebrae can be palpated on the posterior midline of the human body. The function of the spine is to support the trunk and protect the spinal cord. When viewed from the front, the spine is straight. If it is curved, it will be diagnosed as scoliosis. When viewed from the side, the spine is not straight. There are four physiological curvatures of the neck, thoracic, lumbar and sacrum , The physiological curvature of the spine increases the elasticity of the spine, which is of great significance to maintain the stability of the body's center of gravity and reduce shocks.

When the vertebrae are broken or bent and deformed, the damaged and deformed position of the patient's spine needs to be truncated during treatment, and then re-fixed and connected together with spinal pedicle screws. The spine is squeezed and approached, and an additional guide device is required to guide it to ensure the accuracy of the connection of the spine. However, the existing spine guide device is not accurate and cannot be accurately adjusted according to the patient's body shape. When squeezing the spine, the magnitude of the force cannot be controlled, which will cause secondary damage to the patient's spine. The position of squeezing the spine is at both ends of the cross-section, which will easily lead to the involvement of the human tissues of the spine at both ends, which will further increase the patient's pain. In order to solve this problem, we propose a spinal osteotomy reduction guide device.
