Ligation instrument for the treatment of an atrial appendage and heartearrings ligation system

摘要

The completeness of a league heartearrings ligation by means of a position loop is easily and reliably confirmed. Provided is a ligation instrument for the treatment of an atrial appendage (1), comprising: an insertion section (2), the by a sleeve, which penetrates through a pericardial, is introduced into an interior; a fixing part (3), a distal end of the insertion section (2) on a fixed heart earrings (a); and a sensor (6) at the distal end of the insertion section (2) is provided, and the state of the atrial appendage (a) is detected.
