Description

Technical Field

[0001] The utility model relates to a training device, in particular to a training device for raising the straight legs of lower limbs. Background Art

[0002] Minimally invasive transforaminal endoscopic nucleus pulposus removal has the advantages of less trauma, less bleeding, high safety, fast recovery time, and short hospitalization time. It has been widely used in clinical practice. However, most patients still have poor pain relief and prolonged recovery time after surgery. Among them, 5%-24% are caused by epidural fibrosis (nerve root adhesion). Studies have shown that early straight leg raising exercises can effectively reduce the occurrence of residual pain after surgery in patients with intervertebral disc herniation. Straight leg raising exercises after surgery can repeatedly tense and relax the nerve roots and move up and down, which can also promote blood circulation in the nerve roots, accelerate the self-repair of damaged nerve roots, improve the functional state and strength of the waist muscles, regulate the peripheral muscle pump, and regulate the hydrostatic pressure of the intercellular matrix, which is conducive to the early disappearance of edema and inflammatory reactions of the nerve roots, and at the same time avoid adhesion of local tissues during the repair process after surgery. The Chinese utility model patent with publication number CN216798626U discloses an infrared automatic counting in-situ high leg raising exercise training device, which comprises: an infrared counter, an action detection belt, a telescopic column, and a telescopic column buckle.

[0030] How it works

[0031] The utility model utilizes the angle corresponding to the height, and the patient can raise the lower limbs to a certain height during exercise, thereby meeting the lower limb angle requirements. In addition, as long as the patient raises the lower limbs to a certain height and persists for 5-10 seconds, the ultrasonic ranging module 22 can be triggered to start counting, and the number of exercises is displayed on the liquid crystal display 20. It also has a timing function, which is conducive to urging the patient to perform standardized (angle, frequency) functional exercises after surgery, thereby meeting the requirements of functional exercises after lumbar surgery.

[0032] The utility model uses ultrasonic signals to detect distance, and returns the distance when encountering obstacles. This program sets that when an obstacle appears within 45cm, it is considered that the foot appears. When the next detection distance exceeds 45cm, it is determined that the foot leaves, which is counted once. The ultrasonic ranging module 22 measures the leg length L and height H through ultrasonic ranging. The leg length and height arcsin H / L arcsine function can be used to obtain the leg lifting angle α, and then the angle α changes according to the height H.
