Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a device for assisting lower limb straight leg raising. Background Art

[0002] Straight leg raising training is a training that is often performed by orthopedic patients during the postoperative recovery period. It can effectively speed up the patient's recovery and ensure a good surgical effect. The main function of straight leg raising training is to promote blood circulation in bedridden patients, thereby reducing inflammatory response, reducing edema, and avoiding nerve root adhesion. Early leg raising training can also prevent lower limb muscle atrophy and reduce the incidence of venous thrombosis.

[0003] Existing training devices mainly rely on the patient to lift the legs by themselves, usually with the aid of a rope. However, the rope is easy to slip when in use, causing the legs to collide with the lying surface, which may cause secondary injuries. In addition, the legs cannot be reliably controlled to slowly lie flat. If they are laid flat directly, the legs will also collide with the lying surface, which may cause secondary injuries.

[0004] Therefore, in view of the technical problems described above, there is an urgent need for a device to assist in raising the straight legs of the lower limbs. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technology and provide a device for assisting the straight leg raising of the lower limbs.
