[0002] Spinal surgery is a subspecialty within orthopedics, which includes subspecialties such as joints, spine, trauma, hand surgery, foot and ankle, sports medicine, pediatric orthopedics, and bone tumors. It is a collection of various subspecialties. Spinal surgery mainly diagnoses and treats diseases related to the spine that require surgical operations, as follows: Degenerative diseases: cervical spondylosis, lumbar disc herniation, etc.; deformities: cervical deformities, thoracic and lumbar deformities, scoliosis, etc.; infections: spinal abscesses and non-specific infections, such as tuberculosis; tumors: tumors of the spine itself or spinal tumors that have metastasized to other parts of the body, tumors that grow on nerves, such as intraspinal tumors, etc.; others: such as trauma, common in fractures, etc.

[0003] A search of CN114848255A disclosed a spinal surgery nursing rehabilitation exerciser, which sets a stretching structure on the right side of the bed board, mainly used for stretching the patient's upper body to achieve rehabilitation treatment of the spine, and sets an adjustable driving component for contacting the patient's armpit position to achieve stretching operation on the patient, changing the traditional stretching method at the chin position, and setting two driving components to generate more uniform traction force on the patient's upper body, making the patient more comfortable during stretching, and the armpit position can withstand higher traction force, so when the traction force increases, it can reduce the patient's physical discomfort, and at the same time the stretching effect is better, there is no need to stretch repeatedly, and accidental injury to the body can be avoided.

[0038] Furthermore, the inner wall of the second slide groove opened at the top of the support platform 1 fits snugly with the outer wall of the second slider 322, thereby ensuring a tight fit between the outer wall of the second slider 322 and the inner wall of the second slide groove, thereby ensuring the stability of the second slider 322 during movement.

[0039] Embodiment 3:

[0040] The difference between the above embodiment and this embodiment is that: Figures 1 to 7 As shown, a spinal surgery rehabilitation exerciser, the fixing mechanism 33 includes a restraining belt 331 fixedly connected to the outer wall of the lying plate 3117 and the stretching plate 324, one end of the restraining belt 331 is fixedly connected to the plug plate 332, the outer wall of the plug plate 332 is fixedly connected to the locking block 339, the lying plate 3117 and the outer wall of the stretching plate 324 are fixedly connected to the locking frame 333, the top of the locking frame 333 is provided with a through sliding groove, the inner wall of the through sliding groove is provided with a sliding hole, the inner wall of the sliding hole is fixedly connected to the third spring 334, the third spring 334 is fixedly connected to the second sliding column 335 at one end away from the inner wall of the sliding hole, the second sliding column 335 is fixedly connected to the locking block 336 at one end away from the third spring 334, the bottom end of the outer wall of the second sliding column 335 is fixedly connected to the connecting plate 337, and the outer wall of the connecting plate 337 is fixedly connected to the push rod 338.

[0041] Furthermore, there are two restraint belts 331, which are respectively distributed on the outer walls of the lying board 3117 and the stretching board 324, so that the patient's waist and legs can be fixed synchronously, thereby facilitating the subsequent stretching effect.

[0042] Furthermore, there are several snap-fit ​​blocks 339, which are evenly and equidistantly distributed on the outer wall of the insert plate 332, and a slot is provided between every two snap-fit ​​blocks 339, and the outer wall of the snap-fit ​​block 336 fits snugly with the inner wall of the slot, so that multiple slots can be formed, thereby being able to fix patients of different body shapes while ensuring stability after snap-fitting.

[0043] The implementation principle of a spinal surgery rehabilitation exerciser of the present embodiment is as follows: first, the patient lies flat on the lying board 3117, so that the back lies on the arc board 317, and then the waist and legs are restrained by the fixing mechanism 33, and then the motor 313 can be started, and its output end will drive the telescopic rod 314 to rotate, thereby driving the turntable 315 to rotate, and the rotation of the turntable 315 can drive the massage ball 316 at the top to rotate, so that the patient's spine can be massaged by the rotation of the massage ball 316, and at the same time, the telescopic rod 314 will drive the first gear 319 to rotate during the rotation process, thereby driving the second gears 3110 on both sides thereof to rotate, and the rotation of the second gear 3110 can drive the other two turntables 315 to rotate, so that the entire back of the patient can be massaged and relieved, so as to improve the patient's comfort, and at the same time, during the rotation of the output end of the motor 313, the third gear 3115 can also be driven to rotate, and the rotation of the third gear 3115 can be connected with the rack 31 16 is meshed and rotated, thereby moving along the direction of the rack 3116, so that the motor 313 can be driven to move left and right through the sliding connection between the first slider 312 and the first slider 311, so that the arc plate 317, the turntable 315 and the massage ball 316 can be driven to move synchronously, so that the patient's spine and the entire back can be massaged and relieved from top to bottom in an all-round manner, further improving the rehabilitation effect on the spine and further improving the patient's comfort. When the patient lies flat on the arc plate 317, due to the effect of gravity, the turntable 315 will be pressed downward, and during the movement, the first sliding column 3111 will be driven to move downward on the inner wall of the sliding sleeve 3113, and at the same time, the first spring 3112 will be squeezed during the downward movement of the first sliding column 3111, and then the turntable 315 and the massage ball 316 are pushed upward by the rebound direction of the first spring 3112, so that the massage ball 316 can be more closely fitted to the patient's back and spine, thereby improving the rehabilitation and relief effect.

[0044] When the patient lies flat on the lying board 3117 and the stretching board 324, the motor 313 is started to move through the cooperation between the third gear 3115 and the rack 3116, and then the motor 313 can drive the top rod 329 of its outer wall to move to one side. During the movement of the top rod 329, it will contact and squeeze the force plate 328, and then the force plate 328 will drive the second slider 322 to move on the outer wall of the second slider 321, and at the same time squeeze the second spring 323. In this way, the stretching board 324 can be driven to move to one side through the movement of the second slider 322, thereby performing stretching rehabilitation for the patient. When the patient is stretched to a position where he feels relieved, the motor 313 can be turned off, and then the handle 326 can be turned to drive the screw rod 325 to move downward, so that the screw rod 325 can drive the limiting plate 327 to move downward until it contacts the support platform 1, thereby limiting the stretching board 324.

[0045] When the patient lies on the reclining board 3117 and the stretching board 324, the restraining belt 331 can be pulled to make the plug plate 332 on one side plugged into the card frame 333. While inserting into the card frame 333, the engaging block 339 on the outer wall of the plug plate 332 will squeeze the engaging block 336. When the engaging block 336 is squeezed, the second sliding column 335 can be driven to move inward. At the same time, the third spring 334 will be squeezed during the movement of the second sliding column 335. As the sliding column 335 continues to move downward, the engaging block 336 moves to the engaging block 339. The third spring 334 will rebound and push the card block 336 to be connected in the card slot, completing the limit. In this way, after the plug plate 332 is moved to a suitable position, the patient's waist and legs can be fixed. When the fixation is released, the push rod 338 is directly pushed to drive the connecting plate 337 to move. The movement of the connecting plate 337 can drive the second sliding column 335 to move inward, thereby driving the outer wall of the card block 336 to disengage from the card slot between the locking blocks 339. After the limit is released, the plug plate 332 can be pulled out of the inner wall of the card frame 333.
