Embodiment 1
[0039] Embodiment 1, the first aid external fixation frame for spinal injuries, including a frame body 1, is characterized in that, the upper and lower lateral sides of the frame body 1 are respectively provided with left and right clamping devices at longitudinal intervals, and are located between the two left and right clamping devices on the same side There is a first elastic arc-shaped plate 2 that is rotatably connected to the upper lateral side of the frame body 1. The lower end of the first elastic arc-shaped plate 2 is fixedly connected with a plurality of damping devices, and the lower end of the damping device is connected with a second elastic arc-shaped plate. 3. The first elastic arc-shaped plate 2, the damping device and the second elastic arc-shaped plate 3 form a vertical clamping device, and the left and right clamping devices and the vertical clamping device on the same side pass through the first transmission mechanism and the vertical clamping device respecti...
Embodiment 2
[0041] Embodiment 2. On the basis of Embodiment 1, the damping device includes a plurality of first rectangular tubes 5 fixedly connected to the lower end of the first elastic arc-shaped plate 2 and open at both ends of the upper and lower ends. A piston rod 6 is slidingly fitted, and the lower end of the piston rod 6 is connected with a second elastic arc-shaped plate 3, and the upper end surface of the first rectangular cylinder 5 is connected with a first thin plate 7 in rotation between the longitudinal side walls on both sides of the horizontal direction. The opposite side walls of the two first thin plates 7 are slidably fitted with a second thin plate 8 and the opposite side walls of the two second thin plates 8 are threaded with a first screw 9, and the first screw 9 is rotatably connected to the first On the thin plate 7, a rectangular groove 10 with an open lower end is provided in the middle of the opposite side walls of the two first thin plates 7, and a longitudina...
Embodiment 3
[0043] Embodiment 3, on the basis of Embodiment 1, the frame body 1 includes a head support plate 14, a waist support plate 15, and a leg support plate 16 arranged symmetrically left and right, and the support portion of the waist support plate 15 is in the shape of The lumbar support plate 15 arranged symmetrically on a beveled plane cooperates with each other to form a groove shape with high sides and a low center. On the first L-shaped bar 17 that side wall direction extends and two first L-shaped bars 17 are placed between the head support plate 14 and the waist support plate 15 external parts and are connected with the first electric telescopic link 18, two described legs The upper support plates 16 are respectively sleeved on the second L-shaped rods 19 extending perpendicular to the longitudinal side wall of the leg support plates 16, and the ends of the two second L-shaped rods 19 are away from the head support plate 14 through the second electric telescopic The rods 2...
