Abstract

PONTA DE AGULHA PARA DISPOSITIVO DE BIóPSIA. A presente invenção refere-se a um dispositivo de biópsia que inclui uma porção de corpo, uma ponta, pelo menos uma lâmina, e um cortador. A cânula define pelo menos um lúmen. A cânula é dotada de uma abertura transversal configurada para receber tecido. A ponta é localizada na extremidade distal da cânula, e pode incluir pelo menos duas superfícies cóncavas. A lâmina se estende longitudinalmente a partir da ponta. Uma segunda lâmina pode ainda se estender longitudinalmente a partir da ponta. Lâminas podem ser axialmente empilhadas em relação à cânula. As lâminas podem ainda ser dotadas de comprimentos que diferem um a partir do outro. Adicionalmente, a lâmina pode ser dotada de uma extremidade distal pontiaguda, ou pode ser dotada de uma borda distal curva. A configuração da lâmina e da ponta pode proporcionar força reduzida para penetrar no tecido. A lâmina e a ponta podem produzir o comprimento cortado que é maior ou igual ao comprimento do perímetro externo da cânula.
