23 Jul Medical polycaprolactone membrane as well as preparation method and application of medical polycaprolactone membrane
Abstract
The invention relates to the technical field of medical high polymer materials and discloses a medical polycaprolactone membrane as well as a preparation method and an application of the medical polycaprolactone membrane. The constituents of the membrane include polycaprolactone; the membrane is 0.5-2mm thick; and the membrane is of a planar mesh structure and the mesh aperture of the planar mesh structure is 100-300 microns. Besides, composite additive materials, such as BETA-tricalcium phosphate, hydroxylapatite and coral, also can be added to the membrane. The invention also provides a method for preparing the medical polycaprolactone membrane by use of the 3D printing technology; the membrane is applicable to the field of bone tissue engineering; and the medical polycaprolactone membrane is used for covering a bone defect part and then repairing the bone defect, and therefore, the effects of surrounding and protecting the bone defect part, reducing stem cell loss, preventing surrounding fiber tissue ingrowth and guiding bone regeneration can be achieved.
