Abstract

LIMITADOR DE PROFUNDIDADE DE CÂNULA COM APERTO POR PINÇAMENTO. A presente invenção refere-se a um limitador de profundidade que está configurado para se acoplar a um tubo de cânula de um trocarte. O limitador de profundidade inclui um corpo tendo uma primeira e uma segunda porções de corpo acopladas uma à outra e pivotantes entre as configurações aberta e com aperto. O corpo inclui uma primeira e uma segunda superfícies internas apresentadas pela primeira e pela segunda porções de corpo. Na configuração com aperto, a primeira e a segunda superfícies internas formam uma primeira dimensão transversal, dimensionada para restringir o movimento axial do limitador de profundidade em relação ao tubo de cânula. Na configuração aberta, a primeira e a segunda superfícies internas formam uma segunda dimensão transversal, dimensionada para permitir o movimento axial do limitador de profundidade em relação ao tubo de cânula. O limitador de profundidade inclui um primeiro e um segundo membros de travamento, um dos quais é resilientemente propendido para se engatar ao outro. Os membros de travamento estão configurados para se engatarem um ao outro a fim de travar as porções de corpo na configuração com aperto.
