Abstract

SISTEMA PARA AJUSTAR DINAMICAMENTE A OPERAçãO DE UMA PEçA MANUAL CIRúRGICA. A presente invenção refere-se a método e sistema para o ajuste da quantidade de energia enviada a uma peça manual de um sistema cirúrgico com base em um retomo. Uma tabela é gerada a qual correlaciona as diferenças entre as voltagens e os coeficientes de mudança de uma voltagem da saída do elemento de carga do sistema cirúrgico. Os valores de carga da tabela, tais como os coeficientes de carga mínimo e máximo, podem ser gerados pelo uso de perfis de pulso e o tempo que é necessário para o pulso para alcançar a voltagem predeterminada. Os coeficientes de carga intermediária podem ser determinados pelo uso de interpolação ou outros métodos adequados. A saída do elemento de carga é monitorada na fonte de voltagem, tal como o capacitor, para determinar as primeira e segunda voltagens em diferentes tempos. As referidas voltagens são reduzidas se necessário para compatibilidade com os componentes eletrónicos e convertidas em valores digitais. A diferença entre os dois valores digitais é determinada, e a diferença determinada é utilizada para determinar o coeficiente correspondente no qual o elemento de carga carrega a fonte de voltagem. O coeficiente de carga é proporcionado como uma entrada para o elemento de carga para dinamicamente ajustar o coeficiente de carga, o qual por sua vez, dinamicamente ajusta a energia proporcionada pela fonte de voltagem à peça manual.
