Abstract
a presente invenção refere-se a um instrumento cirúrgico ultrassônico para cortar um tecido de um paciente que inclui um atuador de extremidade que se projeta a partir de um conjunto de eixo, que tem um guia de ondas acústicas configurado para se acoplar de modo acústico a um transdutor ultrassônico. o atuador de extremidade inclui uma lâmina ultrassônica, um braço de aperto e uma primeira almofada de aperto. o braço de aperto é acoplado ao conjunto do eixo e é configurado para se mover de modo seletivo em relação à lâmina ultrassônica a partir de uma posição aberta e em direção a uma lâmina ultrassônica até uma posição fechada. o braço de aperto inclui adicionalmente um ponto de contato configurado para engatar uma porção do conjunto do eixo na posição fechada, inibindo assim movimento adicional do braço de aperto em direção à lâmina ultrassônica. a primeira almofada de aperto permanece, portanto, deslocada em relação à lâmina ultrassônica para evitar que a primeira almofada de aperto entre em contato direto com a lâmina ultrassônica.
