Description
Technical Field
The invention relates to a thrombus-dropping-preventing auricle forceps used for preventing thrombus dropping in a left auricle of a patient with atrial fibrillation (hereinafter referred to as atrial fibrillation) during left auricle plugging operation, wherein the thrombus-dropping-preventing auricle forceps is different from a common auricle forceps due to the fact that an elastic passing area exists after the thrombus dropping is blocked.
Background
Atrial fibrillation is one of the most common arrhythmias, has high disability rate and mortality rate, and can occur in individuals with or without heart disease; currently, there are at least 3350 million patients with atrial fibrillation worldwide and the rate of incidence is as high as 2.5% -3.2% at 500 million new cases per year. In addition to heart rhythm disturbances that can cause palpitations and discomfort, atrial fibrillation is a major hazard in the formation of thrombus in the left atrium, and thus, in the development of various thromboembolic diseases, and is one of the leading causes of death and disability in humans. The left atrial appendage occlusion and transthoracoscopic minimally invasive atrial fibrillation radio frequency ablation are effective modes for treating atrial fibrillation at present, wherein the left atrial appendage occlusion and the transthoracoscopic minimally invasive atrial fibrillation radio frequency ablation are used for isolating and eliminating good-hair parts formed by thrombus, and the left atrial appendage occlusion and the transthoracoscopic minimally invasive atrial fibrillation radio frequency ablation can eliminate atrial fibrillation and restore normal sinus rhythm. Because both the two operations are closed operations (not extracorporeal circulation lower intracardiac direct-view operations), if thrombus is formed in the left auricle of a patient, no matter the left auricle is blocked and/or the minimally invasive atrial fibrillation radio frequency ablation operation is carried out, the thrombus is easy to fall off to cause various embolisms, so that the embolisms become taboos, and a large number of patients cannot benefit by the operation mode.
Disclosure of Invention
The invention aims to solve the problems, and provides the atrial appendage forceps capable of preventing thrombus from falling off in an operation, which can temporarily clamp the root of a left atrial appendage in the operation, so that thrombus in the left atrial appendage cannot enter the left atrial base to cause embolism, and can continuously complete subsequent left atrial appendage occlusion operation and subsequent minimally invasive atrial fibrillation radio frequency ablation operation after clamping, thus greatly expanding the adaptation symptoms of the two operations, improving the safety of the two operations, and benefiting more patients with atrial fibrillation, particularly patients with thrombus formation of the left atrial appendage.
The technical scheme adopted by the invention for solving the technical problems is as follows: the main clamping body of the auricle forceps, namely the bilateral occlusion forceps body, is designed into a shape with the middle part presenting an outward arc shape and mutually mirror surfaces, so that an oval passing area is left in the middle of the forceps body after occlusion clamping, and the purpose of temporary 'elastic blocking' can be achieved by using two rubber belts in a matching way, thereby not only avoiding the risk of embolism caused by the dropping of thrombus in the left auricle due to the operation increase, but also not influencing the smooth completion of the follow-up left auricle occlusion operation.
The bilateral occlusion forceps bodies of the heart-ear forceps for preventing thrombus from falling off are respectively designed in a mirror symmetry and integrated manner, according to different shapes, the unilateral forceps bodies are divided into straight parts, arc parts and inclined parts of the forceps bodies, the arc parts are positioned in the middle of the forceps bodies and are outwards arc-shaped, and therefore the middle parts of the bilateral occlusion forceps bodies are oval-shaped passable areas (unclamped areas) after clamping; before the clamp is used, the two ends of the two rubber belts are respectively fixed in the rubber belt clamping grooves adjacent to the straight parts of the clamp bodies at the two ends of the arc part of the clamp body, so that the rubber belts keep certain tension and are in a tightened state, after the left auricle root is clamped and closed by the clamp bodies at the two sides, the oval passing area formed by the middle arc part of the clamp bodies at the two sides is blocked by the two tightened rubber belts in an elastic way, thrombus in the left auricle can not be separated from the left atrial home part, and the guide wire and the sheath tube can still pass through the area by virtue of the compliance of the guide wire and the sheath tube, so that the smooth completion of the whole process of the left auricle plugging operation is not influenced.
The same parts of the auricle forceps for preventing thrombus from falling off, such as the convex-concave tooth structure of the bilateral occlusion forceps body, the operation arm and the like, are not described again.
The invention has the advantages that the elastic blocking of the accessible area and the rubber band in the middle of the clamping bodies on the two sides of the auricular atrial fibrillation forceps is blocked, so that patients with atrial fibrillation combined with left atrial appendage thrombosis can still safely receive left atrial appendage occlusion operation and further implement minimally invasive atrial fibrillation radio frequency ablation operation, the adaptation of the atrial fibrillation patients to surgical treatment is obviously widened, and more high-risk patients are benefited.
