| titleOfInvention | Clamping device with expandable arm and plugging netting |
| abstract | The invention provides a clamping device with expandable arms and a plugging netting, which comprises an upper clamping assembly, a lower clamping assembly, a base, a locking mechanism, a link arm, an expansion arm and a central plugging netting, wherein the upper clamping assembly is arranged on the upper clamping assembly; the number of the upper clamp assemblies is equal to that of the lower clamp assemblies, and the upper clamp assemblies and the lower clamp assemblies are matched to form clamping parts; backflow at two sides of the clamping device can be effectively blocked through the two side expanding arms, central backflow can be further reduced through the blocking netting of the central area, stress of valve leaflets is reduced, and valve leaflet damage is avoided; the lower clamp component is firmly closed by adopting a mechanical locking mode, so that the clamp is not easy to fall off after being implanted into a body. Meanwhile, the device can implant a clamping device through the femoral vein atrial penetration septum in a minimally invasive mode to repair the mitral valve. The device is characterized in that the operation is finished without stopping jumping in the heart to form an effective double-hole structure, the device shortens the operation time, reduces the wound degree and reduces the operation difficulty and the operation risk. |
