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.

Abstract
The invention relates to a treatment device for a lumbar intervertebral disc, in particular to a treatment device for lumbar disc herniation. The treatment device solves the problems that an existing device for treating the lumbar disc herniation through the naturopathy is complex in structure and not convenient to operate, and an existing traction bed is not obvious in treatment effect. An upper body plate is fixedly arranged on the upper end faces of four supporting sliding blocks, a ball screw nut is installed on a ball screw and is in threaded connection with the ball screw, and the ball screw nut is fixedly connected with the upper body plate. A rotating shaft is arranged at the lower end of a rotating support, the rotating shaft is vertically arranged, the lower end of the rotating shaft is rotationally connected with a rack, the upper body plate and a lower body plate are sequentially arranged in the length direction of the rack, the end, close to the upper body plate, of the lower body plate is hinged to the upper end of the rotating support, a lower body plate rotating drive motor is fixedly arranged at the lower portion of the rack, a crank is installed on an output shaft of the lower body plate rotating drive motor, a ball pair sliding block is arranged on the crank, the lower end of a connecting rod is connected with the ball pair sliding block, and the upper end of the connecting rod is hinged to the lower body plate. The device is used for treating the lumbar disc herniation.
Description
technical field [0001] The invention relates to a treatment device, in particular to a medical device for rehabilitation treatment of lumbar intervertebral disc herniation. Background technique [0002] Lumbar disc herniation is a common and frequently-occurring disease in orthopedics, especially in spinal surgery. The disease is caused by the rupture of the fibrous ring of the lumbar intervertebral disc, the protrusion of the nucleus pulposus, and the stimulation or compression of the dura mater and nerve roots. Therefore, the effective way to treat this disease is to eliminate the stimulation and compression. [0003] In terms of treatment methods, it can be mainly divided into surgical treatment and non-surgical treatment. And clinical medical experiments have proved that most patients can use non-surgical methods to achieve a good therapeutic effect, only in the case of non-surgical treatment ineffective surgical treatment. [0004] Back treatment is one of the non-sur...
