A kind of prosthetic eye and its manufacturing method

Abstract

The invention relates to a prosthetic eye, which includes a prosthetic eye seat, a peptide joint and a prosthetic eye sheet; the prosthetic eye seat includes an active layer, a support layer, a buffer layer and a volume layer arranged sequentially from outside to inside, and has a penetrating active layer, a supporting A plurality of through pipes and input pipes of the layer, the buffer layer and the volume layer, the plurality of through pipes extend from the outer surface of the volume layer to the outer surface of the active layer, supporting the active layer, the support layer, the buffer layer and the volume layer; The tube is a hollow structure, providing a channel so that the medicine and / or growth factor can seep from the volume to the outside of the active layer; a one-way valve is set in the input tube to provide a channel for entering the medicine and / or bioactive factor. The invention provides a multi-layer structure to increase buffering and supporting functions, improve the stability and safety of the structure, so that the spherical surface of the prosthetic eye is not easy to collapse, so that it is not easy to be deformed by the extrusion of eye muscles, and at the same time, the volume layer has the ability to reduce rejection. Bactericidal agents such as ofloxacin or ofloxacin, which slowly permeate and flow into the eye through the tube, enhance the compatibility of human tissue, reduce the infection of complications, increase safety and stability, enhance the durability of use, and realize long-term administration medicine.

Description

technical field [0001] The invention relates to an artificial eye and the field of its manufacture. Background technique [0002] Eye disease patients often have serious complications after eyeball removal, such as sunken eye sockets, collapsed eyelids, inability to open and close, atrophy of eye muscles, and often lead to dust and bacteria entering the eyes, resulting in infection. In this case, a prosthetic eye is usually implanted to fill the area after enucleation to reduce infection and restore the appearance. In the prior art, prosthetic eyes are usually made of a single material, such as hydroxyapatite, which reacts with calcium carbonate to obtain porous hydroxyapatite, which is made into a spherical object to fill the missing part of the eyeball. However, this single material will lead to average biocompatibility, and long-term placement in the eye socket will cause eye socket vascularization, new blood vessels and tissues will grow slowly to the periphery, and inc...

Problems solved by technology

However, this single material will lead to average biocompatibility, long-term placement in the eye socket will cause eye socket vascularization, new blood vessels and tissues will grow slowly to the periphery, and increase the risk of eye socket infection and exposure

At the same time, the pure spherical structure of the prosthetic eye is single, without the buffer and support of the multi-layer structure, it will cause the spherical surface to collapse, be deformed by the extrusion of eye muscles, and have poor plasticity, it will be difficult to maintain the spherical structure for a long time, changing the appearance of the eye Moreover, the function of the traditional prosthetic eye is single, there is no way to carry out long-term maintenance, and the problems of rejection, vascularization and histocompatibility have not been effectively solved, because the pure spherical structure is difficult to administer drugs, and it is difficult to maintain long-term implantation in the eye socket.
