Universal adjusting type left auricle clipping device for cardiovascular medicine department

Abstract

The invention relates to a universal adjusting type left auricle clipping device for cardiovascular medicine, which comprises an operating handle, a hollow rod, an auricle clip bracket, an auricle clip and a pull wire, and is characterized in that a universal adjusting mechanism is arranged in the operating handle and the hollow rod; the universal adjusting mechanism comprises a front ball socket seat, a front ball head rod, a linkage rod, a rear ball socket seat, a rear ball head and an adjusting deflector rod. The device is ingenious in structure and reasonable in design, by arranging the universal adjusting mechanism, the positions of the ear clip bracket and the auricular appendage clip can be flexibly adjusted according to actual conditions in an operation, the ear clip bracket and the auricular appendage clip are accurately positioned to the operation position, operation operation is facilitated, the whole adjusting process is completed through the adjusting shifting rod and the operating handle located outside the chest, and the operation efficiency is improved. Operation difficulty is greatly reduced, operation time is saved, and operation quality is improved.

Description

technical field [0001] The invention relates to a universally adjustable left atrial appendage clamp for cardiovascular internal medicine, which belongs to the technical field of medical instruments. Background technique [0002] Atrial fibrillation, abbreviated as atrial fibrillation, is one of the most common clinical arrhythmias. According to clinical statistics, the stroke risk of patients with atrial fibrillation is 5 times higher than that of the general population, and the incidence of stroke caused by atrial fibrillation in China is about 13.0% to 13.4%. As one of the main sources of cardiogenic stroke, the left atrial appendage has always attracted the attention of the medical community, and has been named "the most dangerous human appendage" by the medical community. The risk of thromboembolism such as cerebral infarction, mesenteric artery embolism, and peripheral vascular embolism. [0003] At present, the means of preventing embolism in patients with atrial fi...

Problems solved by technology

In clinical use, the bending position of the ear clip bracket needs to be pre-adjusted and then fixed. Once it enters the body, it cannot be adjusted again. However, in clinical operation, it is difficult for us to accurately pre-adjust the ear clip bracket to a very suitable position. Sometimes, if the adjustment is not in place, it will bring great inconvenience to the surgical treatment. If it is light, it will increase the difficulty of the operation, and if it is serious, it will be necessary to withdraw the left atrial appendage clip again and then adjust it, which will prolong the operation time and increase the difficulty of the operation.
