Abstract

The invention discloses a biological membrane tissue optical detection cutting method and system based on weak coherence interference. A die cutting assembly is placed above the biological tissue, and a biological membrane tissue is placed in the die cutting assembly; detecting the thickness of the target area of the biological membrane tissue through the die cutting assembly by using an optical coherence imaging (OCT) system; based on the thickness of the target area of the biological membrane tissue, a mold in a mold cutting assembly is controlled to cut the target area to obtain the artificial heart bioprosthetic valve leaflet. According to the invention, the micrometer precision and non-contact measurement of the thickness of the biofilm tissue can be realized, and the cutting of the artificial heart biovalve leaflets with uniform thickness can be realized quickly.

Description

technical field [0001] The present invention relates to a method and system for processing biofilm tissue, and more particularly relates to a weakly coherent optical detection and cutting method, system and mold for evaluating and cutting biofilm tissue to obtain artificial heart biovalve leaflets. Background technique [0002] A normal natural heart consists of the aortic, mitral, tricuspid and pulmonary valves, each of which has one-way leaflets that control the directional flow of blood through the heart. When the heart valve is diseased or damaged, in order for the heart to work normally, valve replacement surgery can be performed to replace the human body's own heart valve with an artificial heart biovalve. [0003] Artificial heart biological valves are made of biological tissue materials, such as using bovine pericardium tissue and pig pericardium tissue to make a single leaflet of artificial heart biological valves. A typical procedure commonly used to prepare biopr...
