Controlled stent for kyphotic surgery

Abstract

A controlled stent for kyphotic surgery is used for ankylosing spondylitis kyphosis osteotomy reduction surgery, and comprises a rectangular front bedplate arranged on a base for supporting the head and shoulders of a patient, a rectangular rear bedplate for supporting the buttocks and legs of the patient, and a curved plate for supporting the chest and abdomen of the patient, wherein the curved plate is formed of a plurality of support plates on parallel hinges by connection, is horizontally connected and fixed on the base through a height adjustment mechanism, and can move up and down under the drive of the height adjustment mechanism. Through the arrangement of the curved plate structure for supporting the chest and abdomen, the controlled stent for kyphotic surgery, provided by the invention, realizes digital and automatic adjustment of the spinal curvature of a patient according to the need of a surgery, the operation is simple and quick, the control precision is high, time-consuming is less, secondary damage to the patient is small, and the patient's comfort is high.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a controllable bracket used for ankylosing spondylitis kyphosis osteotomy reduction operation. Background technique [0002] Kyphosis is a common spinal deformity. The physiological kyphosis of normal thoracic spine is less than 50°, and the apex of kyphosis is at T6-8, forming a balanced physiological arc with lumbar lordosis. At this time, the vertical gravity line of sagittal plane passes through C1T1T12 and S1, maintaining the best physiological curve and body Balance to ensure that the human body can look forward normally. Congenital spinal deformity, spinal trauma, tuberculosis and other diseases can lead to increased kyphosis angle. When the kyphosis is greater than 60°, the deformity will continue to aggravate and cause back pain and even paraplegia. [0003] Kyphosis surgery is an effective method to restore the forward vision and the physiologic...

Problems solved by technology

However, this approach has major disadvantages. First, the stability of the patient is poor when the patient is in a prone position on a narrow operating bed; It is difficult to make fine adjustments to meet the surgical requirements, thereby increasing the risk of surgical failure; third, it is easy to cause pressure on the ...
