Auricle clamp conveying system

Abstract

The invention discloses an auricle clamp conveying system. The system comprises a fixing base, a connecting rod, a handle device and a rotating mechanism, the rotating mechanism at least comprises a first connecting part, a second connecting part and a rotating shaft, a first shaft hole and a second shaft hole are formed in the first connecting part and the second connecting part respectively, therotating shaft penetrates through the first shaft hole and the second shaft hole to movably connect the first connecting part and the second connecting part, the handle device is connected with the rear end of the connecting rod, the front end of the connecting rod is connected with the first connecting portion, and the fixing seat is connected with the second connecting portion. The angle can beconveniently and freely switched, the operation is convenient, and the operation difficulty is reduced.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to an auricle clip delivery system. Background technique [0002] Atrial fibrillation is the most common arrhythmia in clinical practice. Its symptoms are irregular heartbeats. The incidence rate of atrial fibrillation in the general population is 0.5% to 1.5%. There are 33.5 million patients with atrial fibrillation worldwide, and there are about 8 million patients with atrial fibrillation in my country. Patients with atrial fibrillation have a very high risk of stroke. In China, stroke is an important cause of death, and strokes caused by atrial fibrillation usually have more severe clinical manifestations, higher mortality rates, and are more likely to recur. [0003] At present, there are three main ways to prevent stroke in patients with atrial fibrillation: [0004] 1. Anticoagulant drug therapy, such as warfarin, but the application of warfarin has a certain ble...

AI Technical Summary

Problems solved by technology

[0004] 1. Anticoagulant drug therapy, such as warfarin, but the application of warfarin has a certain bleeding risk and requires frequent monitoring. There are many contraindications and side effects, and clinical application is difficult;

[0005] 2. Cardiac surgical resection or ligation of the left atrial appendage, but due to the low rate of complete closure of the left atrial appendage in this method, previous studies have shown that the success rate of complete resection of the left atrial appendage is as high as about 80%, and the risk of surgery is relatively high;

Percutaneous intracardiac left atrial appendage occlusion has not been widely used in clinical practice due to its complicated operation, high risk, safety and effectiveness. A wide range of treatment methods. When using this method of treatment, the auricle clip delivery system is required. Currently, the devices used to ligate the left atrial appendage on the market have defects in the delivery system structure design: the auricle clip delivery system cannot freely switch angles , the operation is inconvenient, and the operation is difficult, which will undoubtedly increase the operation time and risk
