Description

Technical Field

[0001] This invention relates to the field of medical assistive devices technology, specifically to a neurosurgical limb rehabilitation training device. Background Technology

[0002] Neurosurgery primarily treats diseases of the brain, spinal cord, and other nervous systems caused by trauma, such as life-threatening cerebral hemorrhage, head injuries from car accidents, or brain tumors requiring surgical intervention. After neurosurgery, patients require rehabilitation training to facilitate rapid limb recovery.

[0003] Current limb rehabilitation training devices are inconvenient to operate, and the upper and lower limbs are set up separately, which cannot coordinate the training of the upper and lower limbs and results in poor adaptability. Secondly, many bedridden patients can only perform local limb rehabilitation training with the help of nursing staff, which not only increases the workload of nursing staff, but also greatly affects the normal recovery of patients. Furthermore, the existing exercise rehabilitation equipment has limited functions, making the exercise less interesting for patients and failing to motivate them to persist in exercising, which greatly prolongs the patient's recovery period.

[0004] In summary, there is an urgent need to design a neurosurgical limb rehabilitation training device that overcomes the aforementioned problems. Summary of the Invention

[0050] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0051] Please see Figures 1 to 7 A neurosurgical limb rehabilitation training device includes a bed board 1 and a support leg 2, wherein the lower end of the support leg 2 is provided with a universal wheel 21 with a brake.

[0052] The upper surface of the bed board 1 is provided with an upper limb exercise mechanism 3 and a lower limb exercise mechanism 4 from the head to the foot of the bed, and the lower end of the bed board 1 is provided with a box 5.

[0053] The upper limb exercise mechanism 3 includes support frames 31 respectively located on both sides of the head end of the bed board 1, main pulleys 32 and guide pulleys 33 located on the support frames 31, pull ropes 34 provided on the main pulleys 32 and guide pulleys 33, one end of the pull ropes 34 is provided with a handle 35, and the other end passes through the support frame 31 and is fixedly connected to the first linkage mechanism 6 located inside the housing 5; the main pulleys 32 can be slidably mounted on the support frame 31 through sleeves 37, so that the patient can adjust the front and back position of the handles 35 according to his own needs. Correspondingly, a number of limiting holes 36 can be provided on the support frame 31, so that the fixing bolts 38 can be threaded through the sleeves 37 and connected to the limiting holes 36.

[0054] The upper surface of the bed board 1 at the foot of the bed is provided with first grooves 11 on both sides. The lower limb exercise mechanism 4 includes a leg support frame 41 with one end hinged in the first groove 11. The two leg support frames 41 are rotatably connected at the connection points of the upper and lower legs through the first rotating shaft 42. The lower end of the leg support frame 41 is detachably connected to the first linkage mechanism 6. The leg support frame 41 performs leg lifting movements under the drive of the pull rope 34 and the first linkage mechanism 6.

[0055] The interior of the housing 5 is also provided with two drive devices 7 for driving the two leg support frames 41 to perform leg flexion movements respectively. The upper surface of the bed board 1 is also provided with a back lifting mechanism 8. The lower end of the back lifting mechanism 8 is connected to one end of the second linkage mechanism 9, and the other end of the second linkage mechanism 9 is fixedly connected to the drive device 7. When the drive device 7 drives the leg support frame 41 to perform leg flexion movements, the back lifting mechanism 8 performs back lifting movements under the drive of the second linkage mechanism 9 and the drive device 7.

[0056] This invention offers two exercise methods. The first is active exercise, where the patient lies flat on the bed board 1 with their left and right legs placed on corresponding leg support frames 41. The patient then pulls the handles 35 on the left and right sides of the bed, causing the pull ropes 34 and the first linkage mechanism 6 to move back and forth, thus raising the leg support frames 41. This method is suitable for patients whose hands can pull the handles 35. The second is passive exercise, where the patient lies flat on the bed board 1 with their left and right legs placed on corresponding leg support frames 41. The drive device 7 is then activated, causing the patient to perform leg flexion exercises. Simultaneously, the drive device 7, through the second linkage mechanism 9, drives the back lifting mechanism 8 to perform back lifting exercises, increasing the enjoyment of the exercise process. Furthermore, more severely ill patients do not require assistance from medical staff or family members, reducing their workload and making it easier for patients to maintain the exercise long-term, further shortening the rehabilitation period.

[0057] Preferably, both leg support frames 41 include an upper support frame 411 and a lower support frame 412, each hinged at one end in the first groove 11. The upper support frame 411 and the lower support frame 412 are rotatably connected at the connection points between the thigh and calf via the first pivot 42. The upper support frame 411 and the lower support frame 412 are detachably connected via countersunk screws 413. The end cap of the countersunk screw 413 is provided in the disassembly hole 416 on the upper surface of the upper support frame 411 to avoid abrasion of the patient's leg skin.

[0058] The lower end of the first groove 11 is provided with a first clearance hole 111 for the second linkage mechanism 9 and the driving device 7 to pass through, and the lower support frame 412 is provided with a second clearance hole 4121 for the first linkage mechanism 6 to pass through.

[0059] The lower end of the upper support frame 411 is rotatably connected to a foot pedal 415 via a second rotating shaft 414. The foot pedal 415 is provided with an elastic fixing strap 4151, which can fix the patient's foot and prevent it from easily detaching from the upper and lower support frames.

[0060] In this embodiment, the second linkage mechanism 9 and the driving device 7 are connected to the lower support frame 412 through the first clearance hole 111; the upper support frame 411 is connected to the upper support frame 412 through the first clearance hole 111 and the second clearance hole 4121; since both the upper support frame 411 and the lower support frame 412 are detachably connected by countersunk screws 413, when the patient needs passive exercise, that is, when the driving device 7 and the second linkage mechanism 9 need to drive the upper and lower support frames to exercise together, it is not necessary to remove the countersunk screws 413, but it is necessary to separate the first linkage mechanism 6 from the upper support frame 411. In this embodiment, as shown... Figure 5 As shown, the first linkage mechanism 6 and the upper support frame 411 can be connected by a snap-fit, making it easy to separate the two. When the patient needs to exercise actively, he / she needs to pull the handle 35 to drive the first linkage mechanism 6 and then drive the upper support frame 411 to exercise his / her legs. The countersunk screw 413 needs to be removed before he / she can exercise.

[0061] Preferably, the support frame 31 has a cavity 311 inside, and the bed board 1 at the lower end of the cavity 311 has a through hole 312 connecting the cavity 311 and the inside of the box 5. The lower end of the box 5 corresponding to the through hole 312 has an extension cavity 51. The bottom end of the extension cavity 51 is fixedly connected to the rack 62 by a first spring 61, and the upper end of the rack 62 is fixedly connected to the pull rope 34.

[0062] The first linkage mechanism 6 includes a first lead screw 64 connected to the inside of the housing 5 via a first bracket 63, a first lead screw nut 65 rotatably mounted on the first lead screw 64, a first horizontal connecting rod 67 connected to the lower end of the first lead screw nut 65 via a first connecting block 66, and a first inclined rod 68 hinged to one end of the first horizontal connecting rod 67. The other end of the first inclined rod 68 passes through the first clearance hole 111 and the second clearance hole 4121 and is hinged to the lower end of the lower support frame 412.

[0063] The first lead screw nut 65 extends from the first bracket 63 near the rack 62 and is connected to the driven bevel gear 69. Two second brackets 610 are provided on the lower wall of the housing 5. A third rotating shaft 612 is connected between the two second brackets 610 through a bearing 611. A driving bevel gear 613 and a spur gear 614 are fitted on the third rotating shaft 612. The driving bevel gear 613 is meshed with the driven bevel gear 69, and the spur gear 614 is meshed with the rack 62.

[0064] In this embodiment, pulling down the handle 35 causes the rack 62 to move upward via the pull rope 34. The rack 62 drives the spur gear 614 to rotate, which in turn drives the active bevel gear 613 to rotate via the third rotating shaft 612. The active bevel gear 613 drives the driven bevel gear 69, which transmits force to the first lead screw 64, causing it to rotate. The first lead screw 64 drives the first lead screw nut 65 to slide forward, which in turn drives the first horizontal connecting rod 67 to move forward via the connecting block 66. This gradually reduces the angle between the first inclined rod 68 and the first horizontal connecting rod 67, from an obtuse angle to 90 degrees. Therefore, the first inclined rod 68 gradually lifts the end of the upper support frame 411. Since the other end of the upper support frame 411 is hinged to the first groove 11, the upper support frame 411 can drive the patient's leg to perform a leg-lifting movement. It should be noted that, as Figure 5 As shown, the lower end of the upper support frame 411 is provided with a slot 4111, and the upper end of the first diagonal rod 68 is provided with a buckle 681, so that the upper support frame 411 and the first diagonal rod 68 are fastened to each other, making it easy to disassemble them when switching exercise modes.

[0065] Preferably, the first support 63 near the lower limb exercise mechanism 4 is provided with a third clearance hole 615 for the first horizontal connecting rod 67 to pass through.

[0066] Preferably, the drive device 7 includes a second lead screw 72 connected to the inside of the housing 5 via a third bracket 71, a second lead screw nut 73 rotatably mounted on the second lead screw 72, a second connecting block 74 fixedly connected to the upper end of the second lead screw nut 73, the upper end of the second connecting block 74 passing through the first clearance hole 111 and hinged to the lower end of the lower support frame 412, and a motor 75 connected to one end of each of the second lead screws 72, the motors 75 rotating alternately in forward and reverse directions.

[0067] In this embodiment, the motor 75 is turned on, which drives the second lead screw 72 to rotate, thereby causing the second lead screw nut 73 to slide forward or backward along the second lead screw 72. When the second lead screw nut 73 slides backward, the second lead screw nut 73 drives the ends of the lower support frame 412 and the upper support frame 411 to slide backward through the second connecting block 74. At the same time, the first rotating shaft 42 at the connection between the upper and lower support frames and the knees can make the patient's knee bend. When the second lead screw nut 73 slides forward, the first rotating shaft 42 and the second connecting block 74 at the connection between the upper and lower support frames and the knees can make the patient's leg gradually straighten, thereby prompting the patient to perform leg flexion exercises to achieve the purpose of leg exercise.

[0068] Preferably, the back lifting mechanism 8 includes a back support plate 81, one end of which is hinged to the bed board 1 and has a receiving groove 82. The lower end of the receiving groove 82 has a fourth clearance hole 83 for the second linkage mechanism 9 to pass through.

[0069] The second linkage mechanism 9 includes a second horizontal connecting rod 91 connected to the lower end of the second lead screw nut 73 via a third connecting block 76, and a second inclined rod 92 hinged to one end of the second horizontal connecting rod 91. The other end of the second inclined rod 92 passes through the fourth clearance hole 83 and is hinged to the lower end of the back support plate 81.

[0070] In this embodiment, when the second lead screw nut 73 slides backward, the second horizontal connecting rod 91 slides backward, and the angle between the second inclined rod 92 and the second horizontal connecting rod 91 gradually decreases, approaching 90 degrees. Therefore, the back support plate 81 can perform back-lifting movements under the action of the second inclined rod 92. Conversely, the back support plate 81 returns to its original position and repeats the movement, allowing the patient's back muscles to be exercised and relaxed.

[0071] Preferably, the third bracket 71 near the back lifting mechanism 8 is provided with a fifth clearance hole 711 through which the second horizontal connecting rod 91 passes.

[0072] Preferably, a hand grip 93 is hinged to the second horizontal connecting rod 91, and a long groove 94 is provided on the bed board 1 for the hand grip 93 to swing back and forth. Both ends of the hand grip 93 are fixedly connected to the two sides of the long groove 94 by a second spring 95. When the patient holds the hand grip 93, it increases the sense of security and allows the hand muscles to be exercised when the patient performs leg flexion and back lifting exercises, achieving two benefits at once.

[0073] Preferably, the bed board 1 is further provided with a lumbar massage mechanism 10, which includes two square holes 101 symmetrically arranged along the vertical center of the bed board, and massage rollers 103 rotatably connected in the square holes 101 through a fourth rotating shaft 102;

[0074] A connecting rod 104 is provided between the two second horizontal connecting rods 91. The two ends of the fourth rotating shaft 102 are respectively fixedly connected to the swing rod 105, and the other end of the swing rod 105 is rotatably connected to the connecting rod 104.

[0075] In this embodiment, when the two second horizontal connecting rods 91 move forward or backward, the connecting rod 104 also moves forward or backward, and the swing rod 105 rotates around the connecting rod 104. Therefore, it drives the massage roller 103 to rotate, thereby achieving the purpose of massaging the patient's waist.

[0076] Preferably, the massage roller 103 is provided with a plurality of massage protrusions 106 evenly distributed to make the patient more comfortable.

[0077] The present invention has been further described above with reference to the embodiments, but the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
