Intervention system for repairing mitral valve

Abstract

The invention discloses an intervention system for repairing a mitral valve. The intervention system comprises two structure units, jacket fixing pipes sleeve the outer sides of the structure units and connected with the jacket fixing pipes in a matched manner, each structure unit comprises an upper tooth portion and a lower tooth portion mutually matched with the upper tooth portion, each tooth portion comprises an upper occlusion tooth portion, an upper-line unidirectional fastening portion a hooking portion, the tail ends of the hooking portions are provided with bent inner threads, the upper occlusion tooth portions are connected with the hooking portions through the upper-line unidirectional fastening portions, each lower tooth portion comprises a lower occlusion tooth portion, a lower-line unidirectional fastening portion, a pipe body portion and a T-shaped reference portion, the tail ends of the T-shaped reference portions are provided with inner threads and tunnel holes, the lower occlusion tooth portions are connected with the T-shaped reference portions through the lower-line unidirectional fastening portions, and the pipe body portions are arranged on the outer sides of the lower-line unidirectional fastening portions. Two valve leaflets can be effectively clamped and folded when the intervention system is used for severe mitral regurgitation patients. A puncture tooth needle more stably penetrates incrassation valve leaflets when the intervention system is used for mitral valve regurgitation and valve leaflet incrassation patients.

Description

technical field [0001] The invention relates to an interventional system for repairing a mitral valve, which belongs to the technical field of medical instruments. Background technique [0002] Mitral regurgitation is the most common heart valve disease. An estimated 4.1 million cases of mitral regurgitation are estimated to occur in the United States alone, of which 1.67 million require surgery, yet only 30,000 (2%) patients with mitral regurgitation receive surgery, and 49% of Patients with mitral regurgitation did not receive surgical treatment because of low cardiac function, many complications, and advanced age, which led to high surgical risks. Another 49% of patients with mitral regurgitation did not go to the hospital and were not treated. [0003] In China, there are about 10 million patients with mitral regurgitation (≥grade 3) who need to be treated. In China, the number of mitral valve surgeries is more than 40,000 cases per year, and the vast majority of patie...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide an interventional system for repairing the mitral valve with strong stability and clamping strength, which solves the problem that MitraClip cannot effectively clamp the valve leaflets for patients with severe regurgitation who urgently need treatment. question
