The present invention demonstrates a product described as a mechanical functional orthosis that can be coupled to one or both hands of quadriplegic or tetraparetic patients with spinal cord injury at level c6 and c7 onwards. This device is activated by the contraction of the wrist extensor, flexor or elbow extensor muscles, and these kinesiological functions are compatible with the remaining functions described and observed in the dermatomes. This orthosis is intended for functional assistance so that these individuals can have as much independence as possible to perform their activities of daily living. The device itself is very functional, easy to train and can be very affordable according to the material used in its construction. It also has an attractive, practical and functional design where everyday equipment and instruments can be coupled for immediate use. . The operating system is based on the mechanical principles of simple machines and all components of the orthosis are designed to make the most of the individual's functionality without unnecessary effort. This device is intended for the rehabilitation process of individuals who have sequelae or injuries caused by spinal cord injuries or other conditions that may affect the spinal cord and is intended for use in health and physical rehabilitation.a presente invenção demonstra um produto descrito como uma órtese funcional mecânica que pode ser acoplada em uma ou ambas as mãos de pacientes tetraplégicos ou tetraparéticos com lesão medular ao nível c6 e c7 em diante. este dispositivo é acionado através da contração dos músculos extensores do punho, flexores ou extensores do cotovelo, sendo que estas funções cinesiológicas são compatíveis com as funções remanescentes descritas e observadas nos dermatomos. esta órtese destina-se ao auxilio funcional para que estes indivíduos possam ter o máximo de independência possível para a realização das suas atividades de vida diária. o dispositivo em si é bastante funcio
