Abstract

LIMITADOR DE PROFUNDIDADE DE CÂNULA DE ELASTÔMERO DE MÚLTIPLAS PAREDES DE TAMANHO UNIVERSAL. A presente invenção refere-se a um limitador de profundidade que é configurado para se acoplar a um tubo de cânula de um trocarte que tem uma dimensão transversal de tubo. O limitador de profundidade inclui uma porção de estrutura externa e uma porção de preensão interna alojada dentro da porção de estrutura externa. A porção de preensão interna inclui uma pluralidade de ressaltos flexíveis entre si, entre uma configuração relaxada e pelo menos uma primeira configuração flexionada. Na configuração relaxada, a pluralidade de ressaltos forma coletivamente uma primeira dimensão transversal eficaz configurada para ser menor que a dimensão transversal do tubo. Na primeira configuração flexionada, a pluralidade de ressaltos forma coletivamente uma segunda dimensão transversal eficaz maior que a primeira dimensão transversal eficaz e configurada para ser igual à dimensão transversal do tubo de modo que a segunda dimensão transversal eficaz seja dimensionada para restringir o movimento axial do limitador de profundidade em relação ao tubo de cânula do trocarte.
