Abstract
método e sistema para esticar igualmente múltiplos fios torcidos. a presente invenção refere-se a um método e sistema que são descritos para esticar fios torcidos estruturais (1) de um tendão em um duto. cada fio torcido (1) é ajustado com sua própria célula de carga (22), de modo que os valores de tensão individual em cada fio torcido individual (1) podem ser medidos durante o esticamento dos fios torcidos (1). as células de carga (22) podem ser removidas após o esticamento oudeixado no local para possibilitar o prosseguimento da monitoração da tensão nos fios torcidos (1). as células de carga (22) podem ser calibradas simultaneamente pelo esticamento dos fios torcidos (1) para uma tensão igual usando macacos individuais (10), então normalizando os sinais provenientes de cada célula de carga (22) para o conhecido valor de tensão igual. uma outra calibração para medição de carga de fio torcido global pode também ser realizada.
