一种左心耳封堵装置
By designing a left atrial appendage occlusion device with an ablation section, the problem of rivet hooks puncturing the atrial appendage was solved by using ablation and hemostasis techniques. This achieved the stability and safety of the occluder, reduced the risk of pericardial effusion, and the material is biodegradable, with a simple and economical structure.

AI Technical Summary
The rivet hooks of existing left atrial appendage occlusion devices are prone to puncturing the atrial appendage, leading to pericardial effusion, which poses a life-threatening risk, and the occlusion effect is unstable.
A left atrial appendage occlusion device was designed, comprising an occluder, an ablation section, and a delivery section. The ablation section is used to ablate and stop bleeding at the junction of the connection section and the tissue. The occluder body consists of a first disc and a second disc. The disc structure design improves the occlusion effect and is made of biodegradable materials. The ablation section uses radiofrequency or plasma ablation to prevent hook puncture.
It reduces the risk of blood flowing into the pericardium, improves the stability and occlusion effect of the occluder, prevents over-occlusion, and the use of biodegradable materials facilitates biodegradation. The structure is simple, economical and practical.
