Description

Lower limb multifunctional exercise device

technical field

The invention relates to the field of medical rehabilitation, in particular to a multifunctional lower limb exercise device.

Background technique

Reduction and fixation rehabilitation runs through the whole process of fracture treatment. For lower extremity fractures, especially hip fractures, NHMRC (National Health and Medical Research Council) and AAOS (American Academy of Orthopedic Surgeons) guidelines do not recommend the routine application of skin traction or bone traction before surgery, thinking that preoperative traction can not only reduce pain or reduce anesthesia The amount of drugs can also cause pain at the traction site or increase the risk of deep vein thrombosis (DVT) in the lower extremities. However, if the displaced fracture cannot be immobilized and fixed, the soft tissue at the fracture site may be re-injured due to the change in the patient's body position, which will aggravate the pain. Although the affected limb is fixed with a triangular pillow in China, the healthy limb is also fixed when the affected limb is fixed. , making physical activity more restricted and increasing the risk of DVT and pressure sores. Plaster or splint fixation for lower extremity fractures, bandaging the affected limb is not conducive to skin cleaning; when preparing for skin cleaning before operation, the external fixation device is often removed, which makes the patient feel like an enemy, the pain intensifies, and one person needs to lift the foot to clean the limb One person cleans (in case of heavy limbs, three people are needed to help clean the limbs). The main purpose of postoperative rehabilitation for lower limb fractures is to restore the patient's joint flexion and extension, standing and walking functions. Perform passive, assisting, and active limb function rehabilitation exercises; in the early postoperative period, continuous passive motion (Continuous PassiveMotion, CPM) is often used to exercise, but this passive exercise is only suitable for 1-3 days after the operation, and assisting training requires medical staff Assist and increase the labor of medical staff; in active functional training, in order to promote the enhancement of limb muscle strength, it is best to carry out resistance training. The gradual increase in strength is of great help to the shaping of the fracture to restore the anatomical position.

In the prior art, there are many kinds of fixation to assist patients with fractures, such as Brown's frame, which needs to be artificially wrapped with gauze bandages or to raise the lower limbs with pillows, which is not conducive to the preoperative cleaning of the skin of patients who need surgical treatment (not only to use The exacerbation of the patient's pain can also make the bed and the Brown support wrapped with gauze wet), continuous passive motion (Continuous Passive Motion, CPM) is suitable for 3 days before exercise, and it is not very helpful for the recovery of the function of the affected limb after 3 days. Intelligent rehabilitation sports equipment is expensive and takes up a lot of space, and most of them only emphasize the exercise of injured limbs, only a single mode of flexion and extension, without a fixed braking device suitable for fractures and a training mode that provides limb elevation. There is no mention of the coordinated movement of the various limbs, and the best form of exercise is the active and coordinated joint movement of the various limbs.
