Embodiment Construction

[0035] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Through the description of the preferred embodiments of the present invention, the advantages of the present invention can be seen and understood more clearly.

[0036] figure 1 It shows the left atrial appendage ligation device of the present invention, which is mainly composed of a ligation thread 1, an outer sheath tube 2, an inner sheath tube 3, a guide wire 4 and a cap 5, wherein the ligation thread 1 is used to ligate the opening of the left atrial appendage, The delivery system can pre-form a looper of the ligature. There are many small knots 6 on the ligation line 1, and the threaded fastener 9 can fix the cap 5 to the outer sheath 2. The function of the thread 9 can also be replaced by a threaded connection between the internal thread provided in the cap and the external thread at the front end of the inner sheath. The front end of the...

Abstract

The invention discloses a device for ligaturing left auricle and the utilization method. the device comprises ligaturing line and conveying system: conveying system comprises internal and external sheath tube, the internal part is hollow; the length of internal sheath tube is little longer than that of external sheath tube, the internal sheath tube can be rested in long sheath tube; godet is set on internal sheath tube, and the front part is equipped with circular ring; hat is connected with front part of internal sheath tube. The utilization method comprises following steps: putting internal sheath tube into external sheath tube, keeping one piercing slot on hat is align to ligaturing line; threading the other end of ligaturing line by using godet through internal sheath tube to form loop; looping left auricle with formed loop, tightening ligaturing line to ligature left auricle. The invention is characterized by small injury area, low risk and prevention of stroke.

Description

Technical field [0001] The invention relates to a device for ligating a body cavity and a method of use thereof, in particular to a device for ligating a left atrial appendage and a method of use thereof. Background technique [0002] Atrial fibrillation (abbreviated as atrial fibrillation or AF) is one of the most common arrhythmias in clinical practice. Studies at home and abroad show that the total incidence of atrial fibrillation in the population is 0.89%. Another 16%-21.5% of strokes (Stroke, also known as stroke or cerebrovascular accident, is a group of acute cerebrovascular diseases with a sudden onset and common features of focal neurological deficits.) Thrombosis caused by atrial fibrillation Stroke caused by shedding, non-valvular atrial fibrillation accounts for 50%-67.1% of cardiogenic stroke cases. The annual incidence of stroke in patients with atrial fibrillation is more than 4%; the fatality and disability rate caused by stroke can reach about 50%. Therefore, th...
