The invention relates to an implantable device for implanting an interbody fusion cage, which comprises a hollow catheter, a sleeve which is slidably arranged in the hollow catheter and has a clamping hole which is matched with the opening at the front end of the sleeve to clamp the interbody fusion cage, and a push rod which is slidably arranged in the sleeve, wherein the sleeve is slidably protruding the hollow catheter to make the interbody fusion cage When reaching the predetermined position, the push rod slides toward the opening end of the sleeve to separate the interbody fusion cage from the opening of the clamping hole and the front end of the sleeve.本創作係為一種植入器械，用以植入椎間融合器，包括：中空導管；套筒，係滑設於該中空導管中，並具有卡合孔，該卡合孔係與該套筒前端之開口配合，以夾帶該椎間融合器；以及推桿，係滑設於該套筒中；其中，該套筒係滑移突出該中空導管以令該椎間融合器抵達預定位置時，該推桿係向該套筒之開口端滑移，以令該椎間融合器脫離該卡合孔及該套筒前端之開口。
