Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a multifunctional rehabilitation device after lumbar surgery. Background Art

[0002] Orthopedic rehabilitation refers to the comprehensive and coordinated application of various medical measures, including physical therapy, exercise therapy and medical engineering methods, to reduce the limb dysfunction of orthopedic patients, so that they can recover their body movement function as soon as possible and return to society. The main contents of orthopedic rehabilitation include: muscle strength training, joint function training, joint proprioception, balance function training, gait training, neurological rehabilitation treatment and the application of prostheses and orthotics.

[0003] The first stage of rehabilitation exercise after lumbar spine surgery is to exercise the lower limb muscle strength to prevent nerve root adhesion, lower limb muscle atrophy and deep vein thrombosis. Supine straight leg raising exercises and lower limb leg kicking exercises are required. Patients have weak leg strength after surgery and it is difficult to persist. Therefore, passive lifting exercises are required. Medical workers or family members need to repeatedly raise the lower limbs alternately, straighten the lower limbs, raise them, and raise the legs alternately, raising them 30-70 degrees, step by step. 3-4 groups per day, 10-20 in each group, and maintain for 3 seconds each time. By raising the lower limbs, the corresponding nerve roots are moved to prevent adhesion, and at the same time, blood circulation in the lower limbs can be promoted.

[0004] At the same time, with the gradual recovery in the later stage, the training intensity can be increased by using the foot pedal device. The device can use the back lifting device to moderately exercise the waist movement as needed, and can exercise the patient's body from all aspects. It is convenient, efficient and highly usable.

[0005] A lumbar spine postoperative rehabilitation exercise device disclosed in publication number CN215132718U can adjust the angle of the leg board according to the patient's recovery condition or the physical conditions of different patients, thereby facilitating passive leg raising exercises for patients recovering from lumbar spine surgery and preventing muscle atrophy and nerve adhesion.

[0006] However, the lumbar vertebra postoperative rehabilitation exercise device has the following disadvantages:

[0008] (2) The device is not convenient for patients to increase training intensity later, and its usage period is short. Utility Model Content
