[0002] Neurosurgery is an important department in the medical field, mainly responsible for treating diseases related to the nervous system. In the rehabilitation process of neurosurgery patients, the recovery of lower limb strength is crucial. Due to damage to the nervous system, patients often face problems such as lower limb muscle atrophy, weakness, and motor dysfunction, which seriously affect the quality of life and rehabilitation process of patients. Traditional lower limb strength training methods, such as physical therapy and body weight training, require the use of training equipment for lower limb training. Among them, resistance rings can be used to achieve lower limb strength training.
[0003] The resistance ring mainly includes an elastic ring, a connecting sleeve sleeved on the left and right middle parts, and an inner arc plate and an outer guard plate fixed on the connecting sleeve.

The patient closes his legs to squeeze the elastic training ring. The elastic training ring deforms under pressure to generate resistance, thereby exercising the muscles of the lower limbs. The patient can gradually adapt to and enhance the function of the lower limbs, accelerating the rehabilitation process.
[0004] However, the patient needs to hold the elastic ring with his hands throughout the training process to prevent the elastic ring from falling when the legs are relaxed, so the patient cannot free his hands to perform other activities, which is a significant limitation.

When the two hooks 9 are connected to the elastic training ring 1, the elastic width of each is stretched, so that the elastic training ring 1 is suspended and not easy to rotate;
[0041] Place the support structure between the patient's legs, adjust the height adjustment structure according to the height of the patient's thighs after sitting down, so that the middle of the elastic training ring 1 in the arc-shaped frame 7 is parallel to the thighs, and the two outer arc-shaped plates contact the inner sides of the patient's legs. The patient closes his legs to squeeze the elastic training ring 1, which deforms under pressure to generate resistance.

The patient can gradually adapt to and enhance the function of the lower limbs, speed up the recovery process, and improve the rehabilitation effect. During the training process, the elastic training ring 1 is tensioned by the arc-shaped frame 7 to prevent it from falling and rotating, so the patient does not need to hold it with both hands, and the training is less restricted.
[0042] The patient closes the double legs and squeezes the elastic training ring 1. The elastic training ring 1 is deformed and elongated up and down under pressure, the top position is in contact with the pressing plate 102, the pressing plate 102 is displaced to drive the spring 103 to be compressed, so that the pressure sensor senses the pressure, sends an electric signal to the microcontroller, the microcontroller amplifies, filters and pre-processes the electric signal, then converts it into a digital signal, and the counting logic judges whether the digital signal exceeds the preset threshold. If yes, the counter increases by 1; otherwise, the current count remains unchanged. After increasing the value, the current count result is displayed on the display screen, and optionally saved to the storage device, so that the patient can more intuitively understand his own training data, make a more scientific and reasonable training plan, ensure the maximization of the training effect, and speed up the lower limb rehabilitation effect.
