Description

Ankle joint rehabilitation instrument for dorsiflexion and eversion synchronous exercise Technical Field The invention relates to the field of ankle rehabilitation, in particular to an ankle rehabilitation instrument for dorsiflexion and eversion synchronous exercise. Background With the increase of living standard, more and more cerebral apoplexy patients have foot drop and foot varus, which are common dysfunction of cerebral apoplexy patients, and foot drop is accompanied by varus due to central or peripheral nerve injury, so that the feet of patients fall down in the walking process to cause secondary injury, and the ankle joint consists of the joint surface at the lower ends of tibia and fibula and a talus pulley, thus the ankle joint is also called as a talus shank joint. The joint fossa of the shape "冂" formed by the lower articular surface of the tibia and the inner and outer ankle articular surfaces together accommodates the talus pulley (joint head), because the front and rear of the pulley joint surface is wide and narrow, when the instep Qu Shi, the wider front part enters the fossa, the joint is stable, the calf muscle and the nerve of the existing part of the patient are damaged, the patient cannot smoothly dorsiflex and evert the ankle joint, the patient cannot normally walk in daily life, and the muscle of the patient needs to be recovered, and the muscle needs to be treated such as massage, acupuncture and the like. The existing ankle rehabilitation process can further treat the ankle by adopting external equipment, muscle groups such as tibialis anterior muscle, fibula longus and the like are stimulated by electric stimulation generally, muscle spasm of a patient is contracted, a mechanical mechanism is adopted to drive feet to rotate around the ankle, but the existing rehabilitation equipment is usually large, the patient needs to go to a specific place of a hospital to perform rehabilitation, the patient with damaged ankle cannot normally walk and move, so that the rehabilitation inconvenience is caused, the existing patient is different in damage condition, different rehabilitation methods are needed under different muscle forces (the muscle force is usually divided into 0-V grade, the 0-grade muscle force is weakest and belongs to complete paralysis, and the V-grade muscle force is normal), but the existing rehabilitation equipment usually only adopts the external auxiliary function and cannot perform targeted rehabilitation training on the patient under different muscle forces. Disclosure of Invention Based on the above, the invention aims to provide an ankle rehabilitation instrument for dorsiflexion and eversion synchronous exercise, which aims to solve the technical problems that equipment is large in size and cannot be used for home use and targeted rehabilitation cannot be carried out according to different muscle forces. The ankle joint rehabilitation instrument comprises a rehabilitation instrument, wherein an electric control mechanism is arranged in the rehabilitation instrument, a dorsiflexion motor is arranged above the electric control mechanism in the rehabilitation instrument, the output end of the dorsiflexion motor is connected with a gear set, the output end of the gear set is connected with a transmission crank, the transmission crank extends to the outer side of the rehabilitation instrument and is connected with a pedal, the bottom end of the pedal is positioned at the outer side of the transmission crank, the everting motor is arranged at the top end of the pedal, a plurality of first binding belts are arranged at the outer side of the rehabilitation instrument, a control box is arranged at the outer side of the control box, a limiting frame is movably connected to the side face of the control box, the limiting frame and the pedal are kept on the same vertical plane, the legs of a patient are placed between the limiting frame and the pedal, the outer side of the limiting frame is connected with a second binding belt, the inner side of the second binding belt is provided with an electric stimulation plate, and the electric stimulation plate is connected with a power supply. Through adopting above-mentioned technical scheme, can drive the running-board through dorsiflexion motor and valgus motor and carry out the multi-angle rotation in step to carry out dorsiflexion and valgus exercise to the ankle joint of shank, and can take exercise the patient of different muscle forces according to patient's specific condition. The invention is further arranged that the gear set comprises driving teeth and driven teeth, wherein the driving teeth are fixed on the output end of the dorsiflexion motor, the driven teeth are fixed on the outer side of the transmission shaft, the driven teeth are meshed with the driving teeth, and the number of teeth of the driving teeth is larger than that of the driven teeth. By adopting the technical scheme, when the dorsiflexion motor is used as
