Abstract

DISPOSITIVO DE ACESSO CIRúRGICO COM CANAL DE VEDAçãO FLEXìVEL. A presente invenção refere-se a um dispositivo de acesso cirúrgico, o qual inclui um alojamento dotado de pelo menos um orifício de acesso no mesmo para receber um instrumento cirúrgico através do mesmo, e pelo menos um canal de instrumento flexível alongado que se estende a partir do alojamento e dotado de um lúmen que se estende através do mesmo e em comunicação de fluido com o pelo menos um orifício de acesso no alojamento. O canal do instrumento é adaptado para se mover a partir de uma primeira configuração recolhida na qual o canal é vedado para substancialmente impedir que fluido flua através do mesmo para uma segunda configuração expandida com a inserção de um instrumento através do mesmo.
