Posterior scleral reinforcement structures visualized by MRI

Abstract

The invention provides a posterior sclera reinforcement structure that can be developed under nuclear magnetic resonance, including a main structure and a developing structure. The developing structure is arranged on the main structure and integrated with the main structure. The developing structure is a hollow structure. The medium is filled with a developer that can be developed under nuclear magnetic resonance, which is used to easily observe the shape and position of the main structure under nuclear magnetic resonance, so as to facilitate postoperative review and inspection, and facilitate medical staff to evaluate the effect of the operation. The material of the invention has good biocompatibility, suitable elasticity and tensile strength, and is not easy to absorb, so that the operation effect is effective for a long time and meets the needs of posterior sclera reinforcement treatment.

Description

technical field [0001] The present invention generally relates to the technical field of ophthalmic disease treatment equipment, and in particular to a developable posterior sclera reinforcement structure, which can be clearly observed under nuclear magnetic resonance. Background technique [0002] High myopia, also known as pathological myopia, is a common blinding eye disease. Retinal detachment, high myopia macular degeneration, retinal choroidal atrophy, posterior staphyloma, lacquer cracks, Fuch's spots and other pathological changes can occur, seriously impairing visual function . my country is one of the countries with the highest incidence of myopia in the world, and the incidence is as high as 70-90%. At the same time, the incidence of high myopia in my country is also very high. The survey of middle school students in western my country in 2015 showed that the prevalence of high myopia was ( 2.9±0.4)%, and middle school students over the age of 17 reached (9.9±3.0)...

Problems solved by technology

This kind of surgery has a history of several decades, and there are many reports at home and abroad. However, there are still some problems in this surgery. For example, biomaterials are usually used as posterior scleral reinforcement materials. Biomaterials are easily absorbed and degraded after surgery, which leads to surgical The effect is difficult to guarantee and maintain

In addition, the existing posterior sclera reinforcement studies are all about reinforcing the structural material itself, and are all based on biological materials such as allogeneic sclera, allogeneic sclera, and allogeneic pericardium. For example, a highly myopic posterior sclera disclosed in the previous Chinese patent CN102525729B Reinforcement biofilm material strips and their production methods, Chinese patent CN103948469B disclosed bio-type scleral contraction tape and its preparation method, Chinese patent application CN110353856A disclosed a biological patch for posterior scleral reinforcement and its preparation method, all It is modified and processed on the basis of biomaterials, which fails to solve the problem of long-term absorption and degradation of biomaterials after surgery. Obviously, postoperative examination and evaluation of surgical effects are not considered, especially there is currently no posterior scleral reinforcement material. It can be observed by current clinical imaging examinations (X-ray, CT, MRI) after operation, which makes it difficult to solve the problems in postoperative examination and evaluation of surgical effect
