Description

Technical Field

[0001] The present invention relates to the field of medical surgical auxiliary instruments, and in particular to a two-dimensional body position adjustment device for radiology departments. Background Art

[0002] When radiology departments take photos of joints and other parts, the joint positions are not clearly displayed due to the lack of specialized diagnostic photography positions, and auxiliary fixation of the joint positions is required to obtain ideal joint photography effects. However, children move around, their feet slide easily, or patients lack good support, which affects the flexion state and the required position cannot be maintained, resulting in poor photography effects. In particular, when photographing joint positions, the angle is extremely important. If the external fixation is not secure and there are no relevant auxiliary surgical instruments to maintain the patient's surgical position, not only the required angle cannot be maintained, but even the position cannot be maintained.

[0003] In summary, the current radiology department has the following technical problems in the process of photographing joint positions: 1) The angle of the position assistive device is fixed, and the adjustment angle span is too large, requiring several assistive devices with different angles. Some positions between two fixed angles cannot be adjusted, resulting in unsatisfactory photographic effects; 2) The existing position assistive devices only have one plane dimension angle change, which cannot meet the two-dimensional angle change of the joint position. The position fixation method is single, the photographic effect is not ideal, and the misdiagnosis rate is high. Summary of the Invention

[0059] By controlling the control rod, the control spindle rotates around the axis core or moves along the direction of the guide rectangular rod. The control spindle and the screw are connected by placing one end of the control spindle into a groove to ensure that the screw can only move axially, and the control spindle can also move and rotate axially. Through the worm gear mechanism and the gear mechanism, the X-axis universal joint and the Y-axis universal joint push the rotating plate to rotate relative to the auxiliary plate through the X-axis column and the Y-axis column. By pressing or pulling up one of the handles, the large and small cone blocks on the extension rod cooperate with the mechanism rod, so that the mechanism rod rotates around the mechanism frame through the rotating shaft, so that the mechanism rod is stuck in the pit on the inner side of the sliding frame or the ring groove gear. When stuck in the sliding frame, the rotation of the ring groove gear will not change the position of the sliding frame, so that the rotating plate or auxiliary plate connected to it through the Y-axis universal joint is fixed. When the mechanism rod is stuck in the ring groove gear, the ring groove gear drives the sliding frame to move in the slide rail fixing frame through the mechanism rod, so that the sliding frame is connected to the Y-axis universal joint connected to the connecting frame, and the connected rotating plate or auxiliary plate rotates relative to the auxiliary plate or rotating plate, thereby achieving the purpose of adjusting the patient's position.
