Abstract

The invention relates to the technical field of medical instruments, in particular to an interventional left auricle ligator and a ligation system with the interventional left auricle ligator. The interventional left auricle ligator comprises a connecting pipe, a snare and a suture, the snare is a flexible ring with two built-in channels and is connected to a pipe opening in one end of the connecting pipe, an open seam connected with one channel is formed in the position, corresponding to the channel, of the inner side of the snare, and a deformable skeleton ring is embedded in the other channel of the snare. The suture penetrates through the two ends of the connecting pipe, a one-way knot is tied between the end of one end of the suture and the body of the connecting pipe to form a retractable ligature coil, the ligature coil is embedded in the corresponding channel from the open seam, the other end of the suture can be pulled outwards relative to the other end of the connecting pipe under the action of external force, and therefore the ligature coil is pulled out from the open seam and contracts. The interventional left auricle ligator has the advantages of being reasonable in structural design and capable of effectively conducting intracardiac ligature operation on a left auricle through percutaneous intervention.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to an interventional left atrial appendage ligator and a ligating system having the same. Background technique

[0002] The left atrial appendage is a long and narrow tubular blind cavity with irregular shape and multiple twists and turns, about the size of a thumb, with an opening ranging from 10mm to 40mm. There are abundant comb muscles and muscle trabeculae in the left atrial appendage, so the blood flow in the left atrial appendage is prone to eddy currents and slowed down, and it is a predisposed site for thrombus formation.

[0003] Patients with atrial fibrillation (AF) have a significantly increased risk of stroke. Studies have shown that 60% of rheumatic heart disease patients with atrial fibrillation (hereinafter referred to as atrial fibrillation) have cardiogenic thrombus from the left atrial appendage (LAA), and 91% of strokes caused by non-valvular atrial fib...
