A three-dimensional CT device in orthopedic surgery based on a mobile convoluted C-arm

Abstract

The invention discloses intraoperative three-dimensional CT equipment based on a mobile convolutional C-shaped arm and belongs to the technical field of medical equipment. The equipment mainly comprises a C-shaped mother arm, a C-shaped sub arm, a C arm rotation shaft, a C arm base, an X-ray transmission device, an X-ray receiving device, an X-ray bulb tube and an X-ray detection array tube. The convex side surface of the C-shaped mother arm is connected with the C arm rotation shaft through a C-shaped sliding rail, the C arm base is connected to the lower portion of the C arm rotation shaft,and an arc groove is formed in the middle line of the concave surface side of the C-shaped mother arm; a pusher is arranged at one end of the C-shaped sub arm, the C-shaped sub arm slides along the arc groove under pushing of the pusher, and finally the C-shaped sub arm and the C-shaped mother arm form an O-shaped arm; the X-ray transmission device and the X-ray receiving device are arranged at the two ends of the C-shaped mother arm respectively, the X-ray bulb tube is arranged on the concave side surface of the C-shaped sub arm, and the X-ray detection array tube is arranged on the inner bottom of the arc groove. In a word, the intraoperative three-dimensional CT equipment is reasonable in design, few in scanning blind area and diverse in function.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a three-dimensional CT device in orthopedic surgery based on a moving and convoluted C-arm. Background technique [0002] With the development of minimally invasive surgery, pedicle screw internal fixation has gradually become a routine operation in thoracolumbar surgery. After a thoracolumbar burst fracture, the fragmented bone will move to the position of the spinal canal, thereby affecting the spinal cord, conus or The cauda equina produces physical pressure. This disorder can cause a loss of some feeling or movement, which can lead to a loss of stability in the spine. The most effective auxiliary examination method for clinical diagnosis of this disease is CT scan. AO type A3 thoracolumbar burst fractures are characterized by the fracture fragments bursting to the surroundings, which may cause compression on the dural sac and nerve roots, resulting in ...
