    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.

    Abstract: An implanting device is used for implanting a membrane in a biological tissue. The implanting device includes a sleeve, a membrane storage element, an injection element and a bubble generating element. The membrane storage element is fixed at the sleeve. The injection element is inserted in the sleeve and the membrane storage element, and includes a capturing end and connecting end. The capturing end is for capturing the membrane and has a hole. The bubble generating element is connected to the connecting end, and is for providing a gas that is then outputted via the hole. By the rotation of the injection element, the capturing end extends straight out of the membrane storage element or retracts straight into the membrane storage element.
