摘要： The present invention relates to a device for use in percutaneous surgery. The device comprises an elongated cannula having an inner dimension and an outer dimension sized for percutaneous introduction into a patient. Said cannula has a distal working end and an opposite proximal end and defines a working channel between said ends, said working channel being sized to receive a tool therethrough. A viewing element is provided having a first end connectable to viewing apparatus and an opposite second end disposed adjacent said distal working end of said cannula. There is further provided a fixture supporting said viewing element adjacent said working channel with said second end disposed adjacent said working end of said cannula, and said working channel has an inner dimension substantially equal to the inner dimension of the cannula.

摘要： SE MUESTRAN DISPOSITIVOS Y PROCEDIMIENTOS PARA REALIZAR OPERACIONES QUIRURGICAS PERCUTANEAS BAJO VISUALIZACION DIRECTA Y A TRAVES DE UNA UNICA CANULA. UN DISPOSITIVO (10) INCLUYE UNA CANULA ALARGADA (20) QUE TIENE UN PRIMER DIAMETRO INTERIOR (DI ) Y UN DIAMETRO EXTERIOR (D O ) DIMENSIONADOS PARA INTRODUCCION PERCUTANEA. LA CANULA (20) DEFINE UN CANAL DE TRABAJO (25) ENTRE SUS EXTREMOS (21,22) QUE TIENE UN SEGUNDO DIAMETRO (D 2 ) IGUAL AL DIAMETRO (D 1 ) DE LA CANULA, DIM ENSIONADO PARA RECIBIR UNA HERRAMIENTA A TRAVES DEL MISMO. EN LA CANULA (20) SE PUEDE INTRODUCIR UN ELEMENTO ALARGADO PARA VISIONADO (50), ADYACENTE AL CANAL DE TRABAJO (25), PREFERENTEMENTE POR UN ACCESORIO (30, 170). EL ACCESORIO (30, 170) INCLUYE UN ALOJAMIENTO/CUERPO (31, 171) QUE PUEDE ACOPLARSE AL EXTREMO PROXIMAL (22) DE LA CANULA (20). EL ALOJAMIENTO (31) DEFINE UN DIAMETRO INTERIOR PARA LA OPTICA (60, 180) QUE SOPORTA UN ELEMENTO DE OBSERVACION (50) PARA TRASLACION Y ROTACION RESPECTO A LA CANULA (20) DE MANERA QUEEL EJE LONGITUDINAL DEL ESPACIO INTERIOR DE LA OPTICA (60, 180) SE DESPLACE PARALELAMENTE A, Y GIRE ALREDEDOR DE, EL EJE LONGITUDINAL DE TRABAJO (25). SE PROPORCIONAN TAMBIEN PROCEDIMIENTOS PARA REALIZAR OPERACIONES QUIRURGICAS POR VIA PERCUTANEA, CON VISUALIZACION DIRECTA Y SIN EXIGIR UN ESPACIO DE TRABAJO MANTENIDO POR FLUIDO.
