Abstract

punho de segurança de bisturi possuindo trava operável pelo usuário. trata-se de um dispositivo de segurança de bisturi (10 ou 100) possuindo um punho (20 ou 120), uma lâmina (40 ou 140) conectada com o punho, e uma proteção (30 ou 130) transportada pelo punho para movimento deslizante entre uma posição retraida na qual a lâmina é exposta para uso, e uma posição estendida para cobrir a borda de corte afiada da lâmina. na posição retraida, um raio da proteção (30 ou 130) aumentado é proporcionado na extremidade distal do punho (20 ou 120) para permitir o controle aperfeiçoado do punho e da orientação da lâmina. o raio da proteção aumentado é posicionado para permitir ao usuário de forma segura segurar uma parte distal grande do punho que é moldada como uma peça única com o suporte da lâmina (26 ou 126) , impedindo movimento não desejado da lâmina ou do punho devido às tolerâncias do mecanismo de proteção. uma mola, tal como uma mola em folhas ou haste em balanço (52 ou 152) , e um par de travas (54, 56) ou fendas (154, 156) são proporcionados para fixar a proteção (30 ou 130) na posição estendida e retraida e para proporcionar resistência durante o movimento entre as duas posições. adicionalmente, um mecanismo de impedimento de recuo, uma trava operável pelo usuário e uma trava operável por força de desprendimento são proporcionados para impedir retração acidental da proteção a partir da posição totalmente estendida e protegida.
