A device (

10

) is provided which includes an elongated cannula (

20

) having a first inner diameter (D

I

) and an outer diameter (D

O

) sized for percutaneous introduction into a patient. The cannula (

20

) defines a working channel (

25

) between its ends (

21, 22

) which has a second diameter (D

2

) equal to the diameter (D

I

) of the cannula sized for receiving a tool therethrough. An elongated viewing element (

50

) is engageable to the cannula (

20

) adjacent the working channel (

25

), preferably by a fixture (

30, 170

). The fixture (

30, 170

) includes a housing/body (

31, 171

) attachable to the proximal end (

22

) of the cannula (

20

). The housing (

31

) defines an optics bore (

60, 180

) to support a viewing element (

50

) for translation and rotation relative to the cannula (

20

) so that the longitudinal axis of the optics bore (

60, 180

) will translate parallel to and rotate about the longitudinal axis of the working channel (

25

). Methods are also provided for performing surgeries percutaneously with direct visualization and without the requirement for a fluid-maintained workspace.
