specific Embodiment approach 1
[0013] Specific implementation mode one: as Figure 1~3 As shown, the treatment device for lumbar intervertebral disc herniation of this embodiment includes an upper body board 1, a ball screw 4, a coupling 5, an upper body board pulling motor 6, a lower body board 7, a rotating bracket 8, a connecting rod 9, and a ball pair slide Block 10, crank 11, lower body plate rotation drive motor 12, frame 13, ball screw nut 43, two slide guide rails 2 and four support slide blocks 3; On the frame 13, two supporting sliders 3 are mounted on each sliding guide rail 2, the upper body plate 1 is fixedly installed on the upper end faces of the four supporting sliders 3, and the ball screw 4 is installed on the frame 13 through a bearing seat. On, one end of the ball screw 4 is affixed to the output shaft of the upper body pulling motor 6 through the coupling 5, the ball screw nut 43 is installed on the ball screw 4 and the two are threaded, the ball screw nut 43 and the The upper body 1 i...
specific Embodiment approach 2
[0016] Specific implementation mode two: as Figure 1~3 As shown, the upper body pulling motor 6 in this embodiment is a DC servo drive motor. Such a design, because the DC servo motor has the characteristics of good controllability, high stability, fast response speed, etc., has linear adjustment characteristics, and is easy to realize computer control. Other components and connections are the same as those in the first embodiment.
specific Embodiment approach 3
[0017] Specific implementation mode three: as figure 2 As shown, the lower body rotation drive motor 12 in this embodiment is a DC servo drive motor. With this design, since the starting torque of the DC servo motor is large and the moment of inertia is small, it can provide enough torque for the starting of the lower body 7, and its better dynamic response speed can cooperate with the angle sensor to realize the speed control with the change of the control signal . Other compositions and connections are the same as those in Embodiment 1 or 2.
