Description

Technical Field

[0001] The present invention belongs to the technical field of intervertebral disc herniation treatment, and in particular is a wearable intervertebral disc herniation postoperative rehabilitation exercise device and an exercise system. Background Art

[0002] The intervertebral disc is a sealed body composed of cartilage plates, annulus fibrosus and nucleus pulposus, located between the two cones of the human spine. Due to long-term sitting and little exercise, the back muscles are loose, the intervertebral disc degenerates and protrudes, and it is easy to cause symptoms of lumbar disc herniation. Severe patients need surgical treatment and combined with postoperative exercise for recovery. After the lumbar patients have undergone surgery, their own physical strength is limited and they cannot perform rehabilitation exercises independently. They need to use devices to assist lumbar patients in postoperative rehabilitation exercises.

[0003] For example, the utility model with announcement number CN215504032U discloses a postoperative rehabilitation exercise auxiliary device for lumbar disc herniation, including a base plate, the top of the base plate is evenly and symmetrically connected to a support rod, the top of the support rod is fixedly connected to a fixed plate, one end of the fixed plate is rotatably installed with a flip plate, the tops of the fixed plate and the flip plate are both attached with attached cushions, and the bottom end of the flip plate is provided with an embedded groove. The structure of the utility model is scientific and reasonable. Through the adjustment massage mechanism, the intensity and effect of the waist massage can be quickly adjusted according to the patient's rehabilitation exercise needs, thereby increasing the adjustability of the postoperative rehabilitation exercise auxiliary device for lumbar disc herniation during use. Through the angle precision adjustment mechanism, the flip angle of the flip plate can be accurately marked and adjusted, which is convenient for patients to adjust the sitting angle during postoperative exercise for lumbar disc herniation, thereby increasing the force adjustability of patients during postoperative exercise for lumbar disc herniation.

[0032] The above scheme is adopted: by utilizing the coordinated use of the control module and the training module, the intelligent debugging of the whole device is realized, so that the patient can realize multifunctional rehabilitation training on the seat 1, achieving the effect of convenient wearing and moving.

[0033] The working principle and use process of the present invention are as follows: when using the device, the patient drives the adjustment motor 63 by using the control panel 7 to drive the first half gear 61 and the second half gear 62 to mesh and rotate, so as to open the first connecting plate 11 and the second connecting plate 12, thereby facilitating the opening and closing of the slot, so that the patient can walk into the chair 1 and sit down, place the legs in the slot, and close the chair 1 by using the adjustment mechanism 6 to maintain a good sitting posture. At this time, the support strap 2 is fixed to the waist by the connecting buckle 22 to achieve treatment. At this time, in order to adapt to patients of different heights, the electric push rod 5 is extended and retracted to drive the fixing box 32 to slide along the chair back 3. , driving the installation box 23 to move synchronously, thereby achieving the effect of driving the position adjustment of the entire support strap 2, improving the applicability of the device. When the patient needs to stand up, the driving assembly 45 is used to drive the two moving plates 44 to approach each other, thereby driving the spring 43 to stretch, so that the fixing rod 42 is away from the fixing hole 232, so that the installation box 23 can be taken out along the card slot 231, thereby achieving rapid separation of the installation box 23 and the fixing box 32, thereby facilitating various forms of use. After the patient stands up, he returns to sit on the chair 1 along the original route. Since the position of the fixing box 32 remains unchanged at this time, the fixing box 32 and the installation box 23 are just connected.
