Safety Mechanism

Abstract: a safety mechanism for an obturator having a sharp distal tip and a notch proximal to the sharp distal tip. the safety mechanism includes a sheath and clip combination configured to releasably couple to a needle hub. the clip is configured to transition between a coupled configuration and an uncoupled configuration. the clip can include a first arm including a first keyhole aperture and a second arm including a second keyhole aperture. the clip can further include a biasing member connecting the first arm to the second arm, the biasing member configured to bias the clip toward the uncoupled configuration. the first keyhole aperture and the second keyhole aperture are configured to slidingly receive the obturator. the clip can transition from the coupled configuration to the uncoupled configuration when the first keyhole aperture and the second keyhole aperture engage the notch.
