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.
