Description

A straight leg raising exercise sling

technical field

The utility model relates to a medical auxiliary binding tool, in particular to a straight leg raising exercise sling.

Background technique

Fractures of the lower extremities are relatively common traumas, and are often treated with manipulative reduction, plaster fixation, small splint fixation, and surgical internal fixation. Due to long-term fixation, the recovery process of the affected limb is often accompanied by joint stiffness or muscle weakness and muscle disuse. Complications such as sexual atrophy will cause great inconvenience to the life and work of patients in the future. Lower limb fractures are a high incidence of orthopedic diseases. Patients with lower limb fractures need a certain amount of lower limb exercise to promote lower limb rehabilitation. Rehabilitation training is very important, but now there are no specific rehabilitation training tools, and patients cannot get out of bed, so they can only use simple belts (bandages) to wrap the soles of the feet and ankles (the fracture site is on the calf bone or femur bone, so fixed on the soles of the feet and ankles to ensure that the legs are straight), and the legs are raised and lowered for exercise by pulling them by hand. This method is not stable, and the exercise movements are not standard enough, which may easily cause secondary injuries to the affected limbs , unfavorable lower limb rehabilitation, and lack of effective auxiliary equipment at present.

As shown in Fig. 5 and Fig. 6, the inventor has proposed a kind of fracture patient's postoperative straight leg raising exerciser, promptly by setting up support on sickbed, and fixing roller 7 and roller 8 on the support, by the patient on leg Bundle the sling (as shown in Figure 7), bind it to the affected limb through the fixing belt 11 of the sling, and then connect the sling through the traction rope 9, the other end of the traction rope has a grip 10, and the patient can pull down the grip 10 Drive the spreader to move up and down, which has the effect of exercise.

As shown in Figure 8, under normal circumstances, when the sling fixes the lower limbs and lifts the lower limbs through the traction rope 9, the lower limbs will swing around the hip joint (position m) to a high position in a circle. When the foot is at x point , the lower limbs are only subjected to upward pulling force, and when the lower limbs are raised to the y point, because the patient mostly adopts a lying or sitting posture for exercise, the hip joint is in contact with the hospital bed, which causes the lower limb to move towards the hip joint with gravity A small thrust is generated to make the lower limbs in a state of internal extrusion, and when the patient continues to pull the traction rope, the lower limbs can be raised to point z. At this time, when the patient pulls the lower limbs at point z again, the lower limbs can be in a pulling state.

At present, for the postoperative rehabilitation of fracture patients, it is generally not recommended for patients to perform large-scale exercises. Therefore, it is generally recommended that patients perform lifting training at a height between x-y, and this inclination angle cannot make the sling produce traction on the lower limbs. Therefore, it is easy to cause slight pain at the fracture site of the patient, and the stretching state is conducive to the growth and reduction of the bone and reduces the pain.

Therefore, how to pull the patient's affected limb through the sling during exercise with a slight elevation is the technical problem to be solved in this application.
