Abstract

SE PRESENTAN UN TROCAR Y UN DISPOSITIVO OBTURADOR DEL TROCAR QUE TIENE UN OBTURADOR Y UN MECANISMO DE FIJACION QUE RESPONDE AL MOVIMIENTO AXIAL PROXIMO DEL OBTURADOR DEL TROCAR. EL OBTURADOR DEL TROCAR TIENE UN EJE OBTURADOR ALARGADO QUE TIENE UN EXTREMO PROXIMO Y UN EXTREMO DISTAL CON UNA PUNTA PERFORADORA MONTADA EN EL MISMO. EL EXTREMO PROXIMO DEL EJE OBTURADOR DEL TROCAR SE ENCUENTRA MONTADO DE FORMA DESLIZANTE EN UN MANGO DE TAL MODO QUE EL EJE OBTURADOR SE PUEDA MOVER AXIALMENTE. SOBRE EL OBTURADOR DEL TROCAR HAY MONTADO DE FORMA DESLIZANTE UN PROTECTOR DE SEGURIDAD QUE TIENE UN EXTREMO DISTAL Y UN EXTREMO PROXIMO CON UN MIEMBRO SALIENTE MONTADO EN EL EXTREMO PROXIMO. EL PROTECTOR DE SEGURIDAD SE PUEDE MOVER AXIALMENTE ENTRE UNA POSICION DISTAL EXTENDIDA Y UNA POSICION PROXIMA RETRAIDA. EL PROTECTOR DE SEGURIDAD SE ENCUENTRA COLOCADO DE FORMA CONCENTRICA ALREDEDOR DEL OBTURADOR. EN EL MANGO DEL OBTURADOR DEL TROCAR HAY MONTADO UN BRAZO DE BLOQUEO PARA FIJAR EL PROTECTOR DE SEGURIDAD EN UNA POSICION EXTENDIDA BLOQUEADA. EN EL EXTREMO PROXIMO DEL EJE OBTURADOR QUE HAY DENTRO DEL MANGO DEL OBTURADOR HAY UN MIEMBRO DE COLLAR ACCIONADOR QUE SE PUEDE MOVER CON EL EJE OBTURADOR. EL COLLAR DEL OBTURADOR DESENGANCHA EL BRAZO DE BLOQUEO CUANDO SE MUEVE HACIA EL EXTREMO PROXIMO Y ENGANCHA EL BRAZO DE BLOQUEO CUANDO SE ARMA EL TROCAR. EL DISPOSITIVO OBTURADOR DEL TROCAR PUEDE ESTAR MONTADO DE FORMA CONCENTRICA EN UNA CANULA DEL TROCAR QUE TIENE UN ORIFICIO PARA RECIBIR AL OBTURADOR DEL TROCAR Y AL PROTECTOR DE SEGURIDAD. EL MECANISMO DE FIJACION SE ACCIONA COMO RESULTADO DEL MOVIMIENTO AXIAL Y PROXIMO DEL OBTURADOR.
