Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical auxiliary equipment, and in particular to an intelligent rehabilitation training walker for fracture patients. Background Art
[0002] Leg fracture refers to the complete or partial break of the leg bone structure, which can also be described as the interruption of the integrity or continuity of the leg bones; tibia and fibula fractures are the most common fractures in leg fractures, accounting for about 13.7% of the total body fractures. After surgery, patients still need functional training to restore the injured part to normal function as much as possible. Scientific and multi-form functional training is required under the guidance of medical staff to reduce complications, heal smoothly, and resume work and life as soon as possible. Effective functional training can improve and increase local blood circulation, enhance muscle strength, prevent tendon and joint capsule adhesion and contracture, soften scars, and restore normal joint and limb function. Reasonable weight-bearing training after surgery can strengthen the longitudinal compression force of the fracture, reduce the fracture gap, make the fracture more stable, improve the fracture end capacity, and promote fracture healing through repeated contraction and relaxation of the injured limb muscles. At the same time, it can also correct minor fracture dislocations, which is conducive to fracture healing.
[0003] At present, patients with tibial fractures mainly use other supporting devices such as crutches to assist walking during the rehabilitation process. The above methods not only have poor stability and operability, but also cannot well activate the muscle groups of the patients' legs when they walk and move, which leads to poor rehabilitation assistance effect for patients.

When walking, the body weight is borne by the bottom plate, and the bottom plate slides upward until the upper end of the square sleeve abuts against the lower end of the limiting sleeve. During the upward movement of the bottom plate, the compressed elastic element 1 provides a certain pressure for the pressure plate and the sole of the foot, thereby assisting the patient to gradually adapt to his own gravity; Furthermore, the upper end of the telescopic rod 2 is hinged to the telescopic rod 1, and the upper part of the telescopic rod 2 is threadedly connected to the fixed sleeve; by rotating the fixed sleeve, the fixed sleeve is controlled to be connected or separated from the telescopic rod, and the telescopic rod 1 and the telescopic rod 2 are controlled to move in parts or be connected to a whole straight rod by the fixed sleeve; Furthermore, an annular water bag is provided on the inner wall of the protective ring; The beneficial effects of the present invention are: The present invention discloses an intelligent rehabilitation training walker for fracture patients, comprising: a thigh fixing mechanism and a calf fixing mechanism; when the patient has a tibia and fibula fracture, the fixing sleeve can be controlled to separate from the telescopic rod 1, so that the telescopic rod 1 and the telescopic rod 2 can swing normally with the human thigh and calf, which does not affect the normal movement of the patient and avoids the problem of leg muscle group degeneration, and can also bear the human body's gravity through the bottom plate and transmit it to the telescopic rod 1 along the telescopic rod 2, so as to avoid the fracture patient's own gravity from compressing and damaging the tibia and fibula during normal movement; When the patient has a fracture in the thigh, the fixing ring is sleeved at the thigh root, the fixing sleeve can be controlled to be sleeved with the telescopic rod, and the telescopic rod 1 and the telescopic rod 2 are connected as a whole, so that the body's gravity is transferred to the thigh root, and the patient's own gravity is prevented from compressing and damaging the fracture position when walking normally.
