Belonging to the field of
organic polymer compound preparation or chemical
processing, the invention provides a tension-free
hernia patch and a preparation method thereof. The patch provided in the invention has good
toughness and strength match, no adverse reaction in the
human body, and excellent
biocompatibility, and is free of
inflammation and
foreign body reaction. When the patch is implanted into organisms,
abdominal adhesions and intestinal fistulas are greatly reduced, so that the patch is a good material for incisional hernias, abdominal hernias, stomal hernias, umbilical hernias and other herniorrhaphies. The patch includes a basal layer made of a non-absorbable material and a
surface coating made of an absorbable material. The
surface coating is softer, and can be completely absorbed by the
human body in 60 days, thus providing time for combination of the basal layer and surrounding tissues. The patch provided in the invention has a simple preparation process and a low manufacturing cost. As a medical tension-free
hernia patch, it has excellent comprehensive performance, and is a safe and reliable patch, thus having great social and economic value.
