A surgical device for percutaneously accessing a tissue of interest. In an embodiment, the surgical device comprises a handle including a groove. In addition, the surgical device comprises a resilient member disposed within the groove. Further, the surgical device comprises a locking sleeve at least partially disposed within the groove with a first end compressing the resilient member and a second end extending beyond the groove and including a flange defining a locking recess having a non-circular cross-section. Still further, the surgical device comprises a cannula including a locking end, the locking end including a locking flange having a non-circular cross-section adapted to be at least partially received by the locking recess to prevent the rotation of the cannula relative to the locking sleeve. Moreover, the surgical device comprises a means for rotationally coupling the cannula to the handle.
