Embodiment Construction

[0026] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0027] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as...

Abstract

The present invention relates to a folding type artificial vitreous body. The folding type artificial vitreous body comprises a balloon, a drainage tube and a drainage valve, one end of the drainage tube communicates with the balloon, the other end of the drainage tube is connected with the drainage valve, after the balloon is filled with filling medium by the drainage valve and the drainage tube,shapes of the balloon are adapted to a portion implanting into eyeballs, wherein one side of the balloon facing eye lens is an optical zone, the optical zone is plane, and a diameter of the optical zone is 9-25 mm. The optical zone of the balloon is designed to be plane to avoid affecting physiological functions of a ciliary body. In addition, the plane optical zone does not cause refraction andeffectively reduces situation where operators produce judgment errors on amount of the injected liquid medium due to refraction in conventional folding type artificial vitreous body.

Description

technical field [0001] The invention relates to the field of biomedical materials, in particular to a foldable artificial glass body, a mold and a manufacturing method thereof. Background technique [0002] The vitreous body is a colorless transparent jelly, accounting for four-fifths of the volume of the eyeball. It is located behind the lens and fills the cavity between the lens and the retina. It has the functions of refracting and supporting the retina. [0003] At present, the implantation of vitreous substitutes, such as silicone oil, heavy silicone oil, and hydrogel, has become an important means of treating diseases of the posterior segment of the eye such as retinopathy, endophthalmitis, and choroidal tumors. However, the therapeutic effects of these substitutes are not ideal, and since these substitutes are directly injected into the vitreous cavity of the human eye, serious complications may occur. For example, silicone oil substitutes, which are widely used in c...
