Description
本発明の実施例によって提供されるヘッド端部光ケーブルをプッシュすることにより半展開状態になる心耳閉鎖装置は、閉鎖装置本体のヘッド端部がヘッド端部制御光ケーブルの一端に接続され、前記閉鎖装置本体の尾端部が尾端部制御光ケーブルの一端に接続され、前記ヘッド端部制御光ケーブルの他方の端部が前記尾端部制御光ケーブルの他方の端部を貫通し、前記閉鎖装置本体は、心耳内における位置を調整する余地を残すために、外鞘管から押し出し後に半展開状態になるように設けられ、ヘッド端部制御光ケーブルをプッシュ又はプルすることで閉鎖器本体のサイズを調整し、尾端部制御光ケーブルを移動させて閉鎖装置本体の心耳内における位置を調整することにより、前記閉鎖装置本体が完全展開後に正確に所望の心耳の閉鎖位置に位置するようにし、手術の難度を低下させ、手術の成功率を向上させる。
