Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0032] Such as Figure 1~3 As shown, the implantable retinal stent 1 provided by the present invention is a transparent and elastically deformable hollow spherical support structure that matches the inner cavity of the eyeball. The stent can be stretched, folded or curled to make its shape longer and thinner, so that it can be implanted through a minimally invasive incision of the vitreous body through a micro-implantation device, and then reset through the elastic and memory deformation of the st...

Abstract

The invention provides an implanted retina support. The support is of a hollowed-out spherical supporting structure which is matched with the entocoele of the eyeball, looks transparent, and can be elastically deformed. The implanted retina support has the following advantages that hollowed-out design of the retina support can avoid increasing of intraocular pressure caused by aqueous fluid circulation obstacles, and reduce the occurrence of postoperative complications.

Description

technical field [0001] The invention relates to an implantable retinal support, which belongs to the technical field of medical instruments. Background technique [0002] Clinically, vitreoretinopathy caused by high myopia, trauma, diabetes and other eye diseases often requires removal of the vitreous body, and implantation of fillers in the vitreous cavity after surgery to support and fix the retina. The current situation is to infuse gas or silicone oil to act as an artificial vitreous body. The disadvantage is that patients have to lie on the bed for several days or weeks, waiting for the gas or silicone oil to stabilize. The gas is generally completely absorbed within a few days or weeks after surgery, while silicone oil is implanted for a long time. Afterwards, it will become turbid and has cytotoxicity, and generally needs to be taken out a few weeks after the operation; some people also try to use hyaluronic acid and oxidized hyaluronic acid, such as Chinese patent CN...
