The present invention generally relates to biomedical engineering and regenerative medicine. Specifically, the present invention relates to development of advanced  tracheal splints for the treatment of tracheal disorders. More particularly, the present invention relates to a process for preparation of biodegradable hybrid polymer  splints, the process comprising, a) carrying polymerization reaction of polycaprolactone (PCL) with pectin in presence of a catalyst to obtain pectin-g-PCL; and b) 3D  printing of pectin-g-PCL. The present invention also relates to a biodegradable hybrid polymer splint comprising honeycomb structure, rectangular convolutions or  combination thereof. Further, the tracheal splints are designed to support tracheal regeneration, enhance cellular interaction, and eliminate the need for additional  surgical procedures for removal.
