Abstract

abstract needle guidance system a system, device and method to determine the location of a needle as it penetrates through a tissue and into a desired site, such as the epidural space, are described. the system contains a light guide, a light source, a light sensor, and a logic unit. when the tip of the needle traverses the relatively dense ligamantum flavum, the reflecting plane of the ligament is positioned at or near zero distance relative to the tip of the device. once the tip enters a less dense epidural space the distance to the reflecting plane becomes greater than zero thus producing a drop in intensity of the reflected light. that drop in the intensity of the reflected light is measured by the light sensor and interpreted by a logic unit to be consistent with entry into the epidural space, allowing the system to provide a signal indicating entry into the epidural space. ___________________________________________________________________________ tradução do resumo resumo patente de invenção: "sistema de orientação de agulha". a invenção refere-se a um sistema e um dispositivo para determinar a localização de uma agulha na medida em que ela penetra através de um tecido e em um local desejado, tal como o espaço epidural. o sistema (1000) contém uma guia de luz (1020), uma fonte de luz (1040), um sensor de luz (1050), e uma unidade lógica (1060). quando a ponta da agulha (1010) atravessar o ligamantum flavum relativamente denso, o plano de reflexão do ligamento ficará posicionado em uma distância zero ou próximo a esta com relação à ponta do dispositivo. uma vez que a ponta entra em um espaço epidural menos denso, a distância para o plano de reflexão fica maior do que zero, produzindo assim uma queda na intensidade da luz refletida. essa queda na intensidade da luz refletida é medida pelo sensor de luz e interpretada por uma unidade lógica a ser consistente com a entrada no espaço epidural, permitindo que o sistema proveja um sinal indicando a entrada no espaço epidural.abstract needle guidance system a system, device and method to determine the location of a needle as it penetrates through a tissue and into a desired site, such as the epidural space, are described.
