  • Publication number: 20200238614
    Abstract: The present disclosure relates to an apparatus and a method for high-precision three-dimensional printing using a salt solution. The apparatus includes a receiving platform system and a printing device. The receiving platform system includes a conductivity cell, a high-voltage electrostatic generation system, a printing platform, and a printing platform driver. The conductivity cell contains salt solution. The high-voltage electrostatic generating system is connected with the conductivity cell. The printing platform is disposed in the salt solution in the conductivity cell. The printing platform driver is connected with the printing platform to drive the printing platform to move along a Z?-axis perpendicular to a horizontal direction. The printing device prints a product on the printing platform. The apparatus is convenient to operate, and solves the problems of low resolution of biological 3D printing, limited product height, and difficulty in using multiple printing methods in combination.

  • Patent number: 9883917
    Abstract: Disclosed is a skin dilator, comprising an expander (11), a pipe network provided on the skin-side surface wall (111) of the expander (11) composed of longitudinal tube (22) and horizontal tube (21) having a reticular structure and communicating with each other, and a guide tube (24) communicating with the pipe network. The skin dilator further comprises several burrs (25) distributed on the skin-side surface wall (111) of the expander (11), and several small apertures (23) communicating the inner cavity of the tube with the outside are provided on both of the longitudinal tube (22) and horizontal tube(21). The tissue expander can be infused biological agents by the filling port to the skin expanding site through the small apertures (23), which may accelerate the expansion growth of skin, prevent skin complications, such as necrosis.
