Abstract

The invention relates to a pericardium screening system and method for an artificial valve, and belongs to the technical field of medical instruments. Comprising an operation table, a pericardium placement frame, a rail type three-dimensional scanner, a graphic processing computer and a projector, one end of the operation table is provided with a pericardium placing frame, and pericardium tissue to be measured is arranged on the pericardium placing frame. A track type three-dimensional scanner and a projector which face the pericardium tissue to be measured are arranged on the operation table on one side of the pericardium placing rack; a graphic processing computer is further arranged on the operation table and connected with the rail type three-dimensional scanner and the projector; and three-dimensional model generation software and thickness peak valley graph generation software are installed in the graph processing computer. The thickness of the pericardial tissue is measured through the three-dimensional scanner, and extra damage to the pericardial tissue is reduced to the maximum extent in a non-contact thickness measurement mode; and the thickness peak-valley graph is projected to the pericardial tissue through the projector, so that the cutting treatment is more convenient, and the screening efficiency is high.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a pericardial screening system and method for artificial valves. Background technique [0002] Heart valves such as the mitral, tricuspid, aortic, and pulmonary valves are sometimes damaged by disease or aging, causing problems with the normal function of the valves. At present, the technology of implanting artificial valves to replace the human body's natural valves by minimally invasive surgery or transcatheter valve replacement surgery is now widely used. The leaflet material of the artificial valve is generally porcine pericardium or bovine pericardium. During manufacture, the porcine pericardium or bovine pericardium needs to be screened out of qualified areas and cut into a specific shape to be installed in the valve holder. [0003] In the prior art, the method of pericardial screening generally adopts the method of multi-point measurement, such as a system, mold ...
