Description
Technical Field
The utility model relates to the field of medical equipment, especially, relate to a medical lower limbs fracture postoperative promotes vertical quantitative stress stimulator and combination bed of bone healing in early stage.
Background
The lower limb fracture is one of the most common diseases in orthopedics, and scientifically guiding the early-stage load training after the lower limb fracture is very important for promoting recovery. Long-time braking after lower limb fracture surgery can affect the healing of bones and surrounding soft tissues, stress stimulation at the fracture end of the fracture is helpful for the healing of the fracture, Walff (Wolff) law proves that proper stress stimulation can promote the healing of the bones, and tissue differentiation theory also considers that the healing of the fracture is affected by mechanical environment. The previous clinical and animal experiments prove that the compressive stress generated by the longitudinal load can drive osteoblasts and fibroblasts to develop towards the direction of differentiating into bones in the early stage of fracture healing, and is favorable for bone healing; the pressure of the complete load during the early healing process of the lower limb fracture can cause delayed healing of the fracture or bone nonunion. Therefore, clinicians recommend that patients with lower limb fractures need to perform partial weight training in an early stage in order to generate an optimal mechanical environment during each stage of fracture healing to promote fracture healing, and the safety of weight training is ensured by controlling the amount of weight bearing during different periods. The early-stage weight training can promote fracture healing, improve walking function of patients and accelerate recovery speed.
Early weight training is a basic principle of the postoperative rehabilitation stage of lower limb fracture. In the current clinical work, patients are generally given early weight training within two weeks after operation, and partial weight training can be started immediately after operation with good fixation and allowable physical conditions. According to the operation treatment condition of the patient and the judgment of the doctor, the patient starts to touch the ground and bear the weight, the weight is gradually increased to reach partial weight, and finally the complete weight is reached. The partial weight prescription for patients varies depending on the type of fracture, the extent of injury, and the experience of the clinician.
However, studies have shown that the current weight training methods mainly include:
the traditional part weight training method comprises the following steps: the method involves oral instruction by the physical therapist and training with electronic scales, and previous studies have also shown that patients cannot accurately follow the weight of a partial load when using oral instruction methods and weight scales. The load bearing method has poor operability and uncertainty of the load bearing weight, so that the compliance of a patient to the load bearing training and the training effect are greatly influenced;
the pressure platform training method comprises the following steps: the pressure platform is the most important measuring equipment in the biomechanics experiment, and is a measuring device with high price and high precision. However, most pressure platforms are only limited to laboratory research and use due to high cost and immobility, and cannot be widely applied clinically;
the application of the feedback technology in weight training, researchers designed a sole pressure monitoring method under the dynamic condition in recent years, and the specific weight of the lower limb is directly measured through the pressure insole by utilizing the intelligent sole pressure insole.
Therefore, the current lower limb weight training methods have the defects, and the effect of the early weight training after the lower limb fracture operation is not ideal. Therefore, the research and design of a safe, effective and practical operation device for helping patients to carry out early scientific weight training has high clinical value.
