摘要： A surgical apparatus (20) For trans-nasal use comprises an outer tubular member (22), an intermediate tubular member (24) slidably mounted within the outer member (22) and moveable between retracted and extended positions, and an inner member (26) slidably mounted within the intermediate tubular member (24) and adapted to be moved between retracted and extended positions. The intermediate member (24) defines a constrained shape when retracted within the outer member (22), and an unconstrained shape when extended from the outer tubular member (22), and the inner member (26) defines an unconstrained shape when in an extended position. The surgical apparatus (20) further comprises end effector means such as a cutter (30) mounted on a distal end (28) of the inner member (26) for cutting tissue from a patient (44) during a biopsy procedure, for example. In use, appropriate extension and retraction of the intermediate and inner members (24, 26) permits the end effector means (30) to be steered through a body cavity to a target site.
