Abstract

A PRESENTE INVENÇÃO ENQUADRA-SE NA ÁREA DOS DISPOSITIVOS MÉDICOS ORTOPÉDICOS, MAIS PRECISAMENTE A UM PARAFUSO DE FIXAÇÃO ÓSSEA COM FIXAÇÃO ANGULAR VARIÁVEL PARA SER INSERIDO NUM ORIFÍCIO ROSCADO DE UMA PLACA ÓSSEA. NA PRESENTE INVENÇÃO, O PARAFUSO DE ÂNGULO VARIÁVEL PERMITE O ENROSCAMENTO CONTÍNUO DOS FILETES DE ROSCA EM CONTACTO COM UMA PLACA, NA REGIÃO SUPERIOR DA ROSCA CABEÇA DO PARAFUSO, O QUE GARANTE UMA MELHOR FIXAÇÃO DO PARAFUSO À PLACA. A GRANDE VANTAGEM TÉCNICA QUE A PRESENTE INVENÇÃO APRESENTA É A DE O PARAFUSO COMPREENDER SULCOS QUE AO ESTAREM COLOCADOS SOMENTE NA REGIÃO INFERIOR DA CABEÇA EM VEZ DE ESTAREM COLOCADOS AO LONGO DE TODO O COMPRIMENTO DA ROSCA, PERMITE QUE A PARTE SUPERIOR DA CABEÇA TENHA FILETES DE ROSCA COMPLETOS, OU SEJA, SEM DESCONTINUIDADES. ASSIM, AO ENROSCAR O PARAFUSO NA PLACA, INDEPENDENTEMENTE DA ANGULAÇÃO POR ELE PERMITIDA, OS FILETES SUPERIORES DA ROSCA QUE ENROSCAM NA PLACA VÃO TER UM ENROSCAMENTO COMPLETO, GARANTINDO QUE O CONTACTO ENTRE A ROSCA DA PLACA E DO PARAFUSO É FEITO COM MAIOR SEGURANÇA, VISTOQUE HÁ MAIS MATERIAL A ESTABELECER ESSE MESMO CONTACTO.
