Title:
IMPLANT RELEASE MECHANISM AND DELIVERY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/007467
Kind Code:
A1
Abstract:
Provided are an implant (8) release mechanism and a delivery apparatus. The release mechanism comprises: a release member (1); a delivery member (2), provided with a delivery cavity (201) having an open end in the axial direction thereof, and driven by a driving force, the release member (1) being suitable for delivery along the delivery cavity (201); and a disengagement member (4), one end of which is suitable for being connected to an implant (8) and the other end of which is suitable for being arranged at a distal end of the delivery member (2). An insertion state and a separation state are provided between the disengagement member (4) and the release member (1); in the insertion state, the disengagement member (4) is limited to the distal end in the delivery cavity (201) by means of the extrusion force of the release member (1) and the constraint force of the delivery member (2); and in the separation state, the extrusion force and the constraint force are released, and the disengagement member (4) retreats from the delivery cavity (201). The disengagement member (4) is subjected to the extrusion force and the constraint force, and is therefore constrained and limited in the delivery cavity (201). After the extrusion force and the constraint force are released, the disengagement member (4) retreats from the delivery cavity (201), thereby achieving the effect of the release member (1) releasing the implant (8) by means of the disengagement member (4), and avoiding false release and advanced release.
