Research on Degradable Medical Lumbar Support Pads Based on Seawater Collagen-Chitosan Interpenetrating Network

This study investigates the development and characterization of degradable medical lumbar support pads fabricated from a seawater collagen-chitosan interpenetrating network (IPN). The aim is to create a biocompatible and mechanically robust material suitable for providing lumbar support and promoting tissue regeneration, while also exhibiting controlled degradation in vivo. Seawater collagen, extracted and purified from marine sources, is selected for its biocompatibility and structural similarity to mammalian collagen. Chitosan, derived from chitin, is incorporated to enhance mechanical strength and modulate degradation kinetics. The IPN structure is formed through a crosslinking process, and the resulting material is characterized in terms of its mechanical properties, degradation rate, biocompatibility, and potential to support cell adhesion and proliferation. In vitro and in vivo studies are conducted to assess the material's performance and safety. The findings demonstrate the potential of seawater collagen-chitosan IPNs as a promising material for degradable medical lumbar support pads, offering a balance of mechanical support, biocompatibility, and controlled degradation.
