摘要

An apparatus (10) for use in percutaneous surgery includes a cannula (11), a first support (20), and a second support (40). The cannula (11) has a channel (12) extending through the cannula (11). The channel (12) has a central axis (14). The first support (20) is associated to the cannula (11) and has a circular perimeter (21) which has a center (22) on the central axis (14). The second support (40) supports a viewing element (200) which extends through the channel (12). The second support (40) is rotatable about the center (22) of the circular perimeter (21) of the first support (20) relative to the first support (20).
