Embodiment Construction

[0012] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0013] A possible therapeutic target for the restoration of walking function after spinal cord injury is the central pattern generator (Central pattern generator, CPG). The proposal of CPG began in 1911. Brown believed that there is a neural network in the spinal cord that can produce rhythmic walking movement patterns without sensory input and brain control. This neural network is CPG. CPGs are defined as refined neural networks that can generate motor activity; and contain the information needed to activate different motor neurons in the appropriate order and intensity to produce motor patterns. ...

Abstract

The invention is applicable to the technical field of medical instruments, and provides a walking assisting system. The system comprises a medicinal carrier containing a recombinant slow virus barrier, a positioning device, an injection device, a signal collecting and encoding device and an illumination device, wherein the recombinant slow virus barrier carries a coding photosensitive ion channel protein gene regulated by a special cell promoter, the positioning device is used for determining a position of a spinal segment, and the injection device used for injecting the medicinal carrier containing the recombinant slow virus barrier into the spinal segment; the signal collecting and encoding device is used for collecting electrical activities corresponding to different behavior movements and encoding the electrical activities so as to determine corresponding light stimulation parameters; and the illumination device is used for receiving the corresponding light stimulation parameters and carrying out corresponding light stimulation on the spinal segment so as to realize functional movement of limbs. The walking assisting system provided by the invention can be widely applied to clinical functional reconstruction.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a walking aid system. Background technique [0002] Spinal cord injury (SCI) is one of the most destructive neurological diseases, and patients have sensory, motor, reflex, urinary and fecal dysfunction below the level of injury. According to epidemiological surveys, there are as many as 500,000 new spinal cord injury patients worldwide each year. There are about 12,000 new cases of spinal cord injury in the United States every year, and the annual treatment cost is as high as more than 7 billion US dollars. There are 60,000 new cases of spinal cord injury patients in my country every year, which is 5-6 times the prevalence rate in the United States and the highest incidence rate in the world. Spinal cord injuries mostly occur in young and middle-aged males, with an average age of 33, and they are the main creators of social wealth. Spinal cord injury often leaves seri...
