    Abstract: The disclosure relates to a spinal intervertebral body fusion device including an adjustable spacer, a first and second pushing piece, and an operative piece. The adjustable spacer includes a first and second supporting plate. The first supporting plate portion is movably installed on the second supporting plate portion. The first and second supporting plate portions form a first and second opening respectively located at two opposite sides of the adjustable spacer. The first pushing piece located at the first opening and is partially clamped by the first and second supporting plate portions. The second pushing piece located at the second opening is partially clamped by the first and second supporting plate portions. The operative piece is movably disposed through the second pushing piece and screwed to the first pushing piece. The operative piece has an annular slot, and the second pushing piece is partially located in the annular slot.

    Abstract: The present disclosure provides a method for manufacturing a porous film, including: preparing a polymer mixture solution, wherein the polymer mixture solution includes polycaprolactone and at least one hydrophobic polymer; adding solid particles as a dispersing agent to the polymer mixture solution and mixing the solid particles with the polymer mixture solution, wherein the amount of solid particles added is enough to convert the polymer mixture solution into a solid mixture; drying the solid mixture to form a film; and washing the film with a washing fluid to remove the solid particles from the film to form the porous film, wherein the weight ratio of the polycaprolactone to the at least one hydrophobic polymer is about 1:0.1-10, and wherein the weight ratio of the polycaprolactone and the at least one hydrophobic polymer to the solid particles is about 1:0.01-250.
