[0030] The present invention will be further described below with reference to the accompanying drawings:

[0031] like Figures 1-9As shown, a lumbar fixation device for a rehabilitation robot includes a lumbar support mechanism. The lumbar support mechanism includes a rear lumbar support plate 101, an extension bracket 102 fixedly connected to the rear lumbar support plate 101, a front crossbar 103 at the front end of the extension bracket 102, and a pin 104 connecting the extension bracket 102 and the front crossbar 103. A spring telescopic rod 105 is fixedly connected to the front crossbar 103, and a front abdominal support plate 106 is fixedly connected to the rear end of the spring telescopic rod 105. Several symmetrically arranged lumbar tightening straps 108 are fixedly connected to both sides of the rear lumbar support plate 101, and Velcro fasteners are fixedly connected to the other ends of the lumbar tightening straps 108. A first Velcro fastener is fixedly connected to the front of the front abdominal support plate 106. The first Velcro patch 107 and the waist tightening belt 108 have Velcro fasteners at one end that can engage with the first Velcro patch 107. A connecting mechanism is provided on the rear side of the lower back support plate 101. A lifting bracket 110 is fixedly connected to the rear side of the lower back support plate 101. An upper body support mechanism is provided on the lifting bracket 110. Limiting telescopic rods 112 are rotatably connected to both sides of the bottom of the extension bracket 102. Leg support mechanisms are provided on the limiting telescopic rods 112. A lower back airbag 109 is fixedly connected to the front side of the lower back support plate 101. The rear end of the front abdominal support plate 106 is arc-shaped. Limiting bolts 111 are threaded onto the lifting bracket 110. Currently, rehabilitation robots are commonly used during postoperative rehabilitation. To ensure the rehabilitation robot can stably support the patient, a body fixation device is needed to secure the patient's body parts to the robot. A lumbar fixation device is particularly important. Since patients' waist and abdominal proportions vary, the lumbar fixation device needs to be adjustable. However, current technology makes adjustment cumbersome, and multiple straps can cause discomfort. Therefore, a more adjustable and comfortable lumbar fixation device is proposed. The caregiver removes one side pin 104, opening the front crossbar 103. The patient then moves into the device, repositions the front crossbar 103, and reinstalls the pin 104. The anterior abdominal support plate 106... Under the action of the spring telescopic rod 105, the waist tightening belt 108 is used to wrap around the patient's waist, and one end is attached to the first Velcro 107. This can directly adapt to the size of the patient's waist, saving the step of adjusting the size. The multiple waist tightening belts 108 not only share the reaction force generated during the patient's rehabilitation and prevent it from bursting, but also can adapt to different sizes according to the changes in the patient's upper and lower waist circumference, thus achieving an easy-to-adjust function. During the fixation process, the lower back airbag 109 supports the patient's lower back, and the front abdominal guard 106 fits the patient's abdomen to avoid the tightness of the restraint belt, which can greatly improve the patient's comfort when using it.

[0032] The connecting mechanism includes a hinge ball head 201 fixedly connected to the rear side of the lumbar support plate 101. A ball seat 202 is hinged to the rear end of the hinge ball head 201. A connecting plate 203 is fixedly connected to the rear end of the ball seat 202. The connecting plate 203 is fixedly connected to the rehabilitation robot. Since the patient needs to move during rehabilitation, there needs to be a certain relative movement ability between the lumbar fixation device and the rehabilitation robot. Therefore, multiple degrees of freedom of movement are achieved by connecting the hinge ball head 201 and the ball seat 202 through a spherical secondary hinge.

[0033] The upper body support mechanism includes a lifting rod 301 slidably connected to a lifting bracket 110. A back panel 302 is fixedly connected to the top of the lifting rod 301. Two symmetrically arranged shoulder tightening straps 303 are rotatably connected to the top of the back panel 302. A front chest panel 304 is fixedly connected to the other end of the shoulder tightening straps 303. A second Velcro closure 306 is fixedly connected to the front side of the front chest panel 304. Two symmetrically arranged underarm tightening straps 305 are fixedly connected to both sides of the back panel 302. Velcro closures are fixedly connected to the other end of the underarm tightening straps 305. The end of the underarm tightening strap 305 with the Velcro closure can cooperate with the second Velcro closure 306. Several limiting holes are opened on the rear side of the lifting rod 301. The limiting hole on the rear side can be matched with the limiting bolt 111 for limiting. The rear side of the front chest guard 304 is set in an arc shape. The front side of the back guard 302 is fixedly connected to the back airbag 307. The caregiver pulls the front chest guard 304 to the patient's chest. During this process, the shoulder tightening strap 303 automatically fits against the patient's shoulder. Then, the underarm tightening strap 305 is pulled to wrap around the patient's armpit and make one end of the underarm tightening strap 305 fit with the second Velcro 306. In this way, the upper body of the patient is fixed. In order to adapt to the patient's body shape, the lifting rod 301 and the lifting bracket 110 can move relative to each other and be fixed by the limiting bolt 111. The arc shape of the back airbag 307 and the front chest guard 304 ensures the comfort of the device.

[0034] The leg support mechanism includes a leg bracket 401 fixedly connected to one end of a limiting telescopic rod 112. Two symmetrically arranged leg guards 402 are rotatably connected to the leg bracket 401. A third Velcro 404 is fixedly connected to the front leg guard 402, and several leg tightening straps 403 are fixedly connected to the rear leg guard 402. Velcro is fixedly connected to the other end of the leg tightening straps 403. The end of the leg tightening straps 403 with Velcro can cooperate with the third Velcro 404. The caregiver flips the leg guards 402 and places the patient's thigh between the two leg guards 402. Then, the caregiver pulls the leg tightening straps 403 around the patient's thigh and makes the other end of the leg tightening straps 403 fit against the leg tightening straps 403, thus completing the fixation of the patient's leg.

[0035] The bonding areas of the first Velcro 107, the second Velcro 306, and the third Velcro 404 are correspondingly larger than one end of the waist tightening belt 108, the underarm tightening belt 305, and the leg tightening belt 403. This arrangement provides a large number of bonding points at one end of the waist tightening belt 108, the underarm tightening belt 305, and the leg tightening belt 403, making it easier to adjust the device.

[0036] Working principle: The caregiver removes the pin 104 on one side, thus opening the front crossbar 103. The patient then moves into the device, the front crossbar 103 is reset, and the pin 104 is reinstalled. The abdominal support plate 106 fits the patient's abdomen under the action of the spring telescopic rod 105. Then, the lumbar tightening belt 108 is wrapped around the patient's waist, with one end attached to the first Velcro closure 107. This directly adapts to the patient's waist size, eliminating the need for size adjustments. Furthermore, the multiple lumbar tightening belts 108 not only distribute the reaction force generated during the patient's recovery but also prevent collapse. The caregiver pulls the front chest guard 304 to the patient's chest. During this process, the shoulder tightening strap 303 automatically rests against the patient's shoulders. Then, the caregiver pulls the underarm tightening strap 305 around the patient's armpit and attaches one end of the underarm tightening strap 305 to the second Velcro 306, thus completing the fixation of the patient's upper body. The caregiver flips the leg guard 402 and places the patient's thigh between the two leg guards 402. Then, the caregiver pulls the leg tightening strap 403 around the patient's thigh and attaches the other end of the leg tightening strap 403 to the leg tightening strap 403, thus completing the fixation of the patient's legs.
