Abstract

TROCARTE. A presente invenção refere-se a um trocarte, que compreende uma camisa para trocarte, uma estrutura de vedação e um obturador, em que a camisa para trocarte compreende uma peça do alojamento da extremidade proximal em forma de tigela, uma porção de extremidade distal e uma porção de bainha entre as duas; a estrutura de vedação compreende uma carcaça superior e uma carcaça inferior integrada uma com a outra; e o obturador compreende um eixo central e uma porção de extremidade proximal que está situada na extremidade proximal do obturador projetado para ser empunhado por um cirurgião; a direção axial do trocarte é definida pela direção de extensão do eixo central que tem, também, uma ponta do obturador na extremidade distal para executar a perfuração; o eixo central passa através da porção de bainha da camisa para trocarte e a estrutura de vedação de uma forma selada e a ponta do obturador do eixo central se estende para fora da porção de extremidade distal da camisa para trocarte quando o trocarte é montado. O trocarte revelado pela presente invenção é caracterizado pelo fato de que: as dimensões axiais da porção de alojamento da extremidade proximal da camisa para trocarte, da carcaça superior da estrutura de vedação e da porção de extremidade proximal do obturador na direção axial do trocarte, respectivamente, são d1, d2 e d3, e d3 é igual a ou maior que 1/2 da soma de d1, d2 e d3. O trocarte revelado pela presente invenção é vantajoso em que, quando o trocarte está em uso, o alojamento da camisa para trocarte e a estrutura de vedação provavelmente não serão separados uma da outra devido ao torque exercido pelo cirurgião à porção unida entre a camisa para trocarte e a estrutura de vedação.
