Bracket of vitreous body cavity for curing retina disease, and manufacturing method

Abstract

A supporting frame of vitreous body cavity for treating retinopathy is a Rugby football-shaped single-layer netted structure with a front opening (1.0-2.2 mm in diameter) and a rear yellow spot hole (0.5-1.5 mm in diameter). Said netted structure is made of Ni-Ti marmem. Its preparing method is also disclosed.

Description

technical field [0001] The invention relates to a medical device, in particular to a vitreous cavity support for treating retinal diseases, and also relates to a manufacturing method of the vitreous cavity support. Background technique [0002] Serious eye trauma, proliferative diabetic retinopathy, recurrent retinal detachment, and giant hole retinal detachment have become one of the major blinding diseases in some developed countries in Europe and the United States. In the past ten years, with the continuous popularization of vitreoretinal surgery and the continuous improvement of instruments and equipment, and the continuous updating of vitreous substitutes, the prognosis of a small number of severe vitreoretinal diseases has been improved to a certain extent. The incidence of complications such as emulsification, secondary glaucoma, corneal decompensation, and the formation and development of PVR is relatively high, especially recurrent retinal detachment and eyeball atr...

Problems solved by technology

In the past ten years, with the continuous popularization of vitreoretinal surgery and the continuous improvement of instruments and equipment, and the continuous updating of vitreous substitutes, the prognosis of a small number of severe vitreoretinal diseases has been improved to a certain extent. The incidence of complications such as emulsification, secondary glaucoma, corneal decompensation, and the formation and development of PVR is relatively high, especially recurrent retinal detachment and eyeball atrophy after silicone oil removal, which greatly reduces the success rate of surgery; In addition, vitreoretinal surgery has relatively high requirements for equipment and surgeons; therefore, research on a new type of vitreous substitute or vitreous cavity support can preserve the eyeball in severe eyeball injuries, proliferative diabetic retinopathy and other serious eye diseases appearance, restoration of aesthetics, and even gaining some degree of vision are important

[0003] Due to the late start of vitreoretinal surgery in China, most of the current domestic research focuses on drugs to inhibit the formation and development of PVR; in foreign countries, research mainly focuses on the update of vitreoretinal surgery equipment and technology, as well as research on vitreous substitutes ; However, liquid and gas are still the main substitutes for the vitreous body at home and abroad, and there are no related reports on the vitreous cavity bracket at home and abroad.
