Description

Lower limb nerve function rehabilitation training device Technical Field The invention relates to the technical field of neurological medical instruments, in particular to a lower limb neurological function rehabilitation training device. Background The core difference between nerve function rehabilitation and traditional limb movement rehabilitation is that the aim is not to purely restore muscle strength or joint mobility, but to reconstruct impaired nerve conduction pathways and central control ability. Functional Electrical Stimulation (FES) can induce muscle to generate functional movement by simulating human nerve electrical signals, effectively activate nerve plasticity, promote the relearning of central nervous system to limb movement, and is suitable for movement dysfunction caused by cerebral apoplexy, spinal cord injury, peripheral nerve injury and the like. The recovery of nerve to muscle control function is a progressive dynamic process, and the clinical rehabilitation practice is definitely divided into two core stages, wherein the early stage is a weak stage of nerve control ability, the muscles of a patient cannot be effectively contracted, even the movement of limbs cannot be controlled autonomously, the stage needs to maintain the joint activity degree, prevent muscular atrophy and tendon contracture and stimulate nerve plasticity through passive guidance, a foundation is laid for nerve channel reconstruction, the later stage is a gradual recovery stage of nerve control ability, the patient can generate certain muscle active contraction, the stage needs to strengthen the cooperative control ability of nerve-muscle through targeted active training, the further remodeling of the nerve channel is promoted, and finally the recovery of the autonomous motor function is realized. According to the Chinese patent application No. CN111068255A, a comprehensive trainer for hemiplegia lower limb is provided, the feet of a patient can be fixed on a foot fixing plate, the inclination angle between the sole and a bottom plate can be adjusted through an air cylinder, the upper part of the lower leg on one diseased side of the patient can be fixed by the front leg supporting component and the rear leg supporting component, the sole which is obliquely fixed on the foot fixing plate is combined, the load is added to the ankle on the diseased side by lifting the leg on the other side, therefore, the lower leg muscle and the foot muscle above the achilles tendon can be exercised, the weak or contracted muscle is activated, the supporting capacity of the leg of the patient is improved, three lifting tables arranged at the front end of the foot fixing component can apply different loads to the leg on the diseased side of the auxiliary patient, the seat lifting mechanism can jack the patient sitting on the seat obliquely, and the patient can be assisted to stand independently for training, and therefore, the patient can perform autonomous training by using the trainer, the training effect is stronger, and the rehabilitation time of the patient can be shortened. Through analyzing the invention and finding in the prior art, the existing rehabilitation equipment is focused on strength training, and lacks a comprehensive instrument which can adapt to the dynamic recovery process and realize seamless connection from passive guidance to active training so as to meet the personalized requirements of different rehabilitation stages. Disclosure of Invention Aiming at the defects existing in the prior art, the invention provides a lower limb nerve function rehabilitation training device, which aims to solve the technical problems that the existing rehabilitation equipment provided in the background art is mainly used for strength training and lacks a comprehensive instrument which can adapt to the dynamic recovery process and realize 'passive guidance-active training' seamless connection so as to meet the individual requirements of different rehabilitation stages. In order to achieve the above purpose, the invention provides the following technical scheme, namely, a lower limb nerve function rehabilitation training device, which comprises: the rack comprises a platform section and a supporting section; The traction mechanism is arranged on the support section and comprises a left connecting rod unit and a right connecting rod unit, the two connecting rod units can be driven by a sliding plate in the control assembly, the sliding plate comprises a sliding section, a first mounting seat and a second mounting seat, and the two connecting rod units can swing alternately under the driving of the sliding section and the guidance of the special-shaped sliding groove group; the fixed assemblies are provided with two, are both arranged on the platform section in a sliding way, are respectively connected with the two connecting rod units, and can convert the alternate swing of the traction mechanism into alternate linear reciprocatin
