Quantitative pressurizing block for posterior sclera

Technical Field

The embodiment of the utility model provides a relate to ophthalmic surgery treatment apparatus technical field, concretely relates to back sclera ration briquetting.

Background

With the remarkable increase of the prevalence rate of high myopia in China in recent years, epidemiological research suggests that high myopia patients reach 2900 ten thousand to 3040 ten thousand, and fundus lesions caused by high myopia become one of the important diseases of irreversible blindness. The traction macular degeneration caused by the high myopia mainly comprises three types of macular central fovea retinal cleavage, macular central fovea retinal detachment and macular hole, and is a group of blindness-causing diseases which seriously affect the visual function of a patient.

At present, several mainstream options exist for clinically treating traction-type macular degeneration, including extramacular compression, vitrectomy (PPV) and vitrectomy combined extramacular compression, and the purpose and key point of the operation are to relieve traction of various factors on retina and restore normal anatomical structure and physiological function of macular region. Extramacular compression helps to relieve the traction (anteroposterior direction) of the posterior scleral staphyloma on the outer retina, shortening the distance required for retinal replacement, while avoiding possible impairment of retinal function by intraocular surgery. Vitrectomy, mainly a pars plana vitrectomy combined with inner limiting membrane ablation, removes tissues (tangential direction) with traction force on the macula part, removes the skeleton structure of pathological proliferation of cells and reduces the possibility of macular membrane recurrence. Vitreous surgery has been considered by researchers to enable anatomical reduction and functional improvement of highly myopic traction macular degeneration. In addition, it has been reported in the literature that analysis of a large number of samples demonstrates that posterior macular scleral reinforcement results in patients with a high rate of retinal replacement.

As the eyeball of a patient with high myopia is changed in anatomy, which is expressed by the growth of the axis of the eye, the irregular appearance of the eyeball and the retroscleral staphyloma, the overall shape of the eyeball can be roughly divided into 4 main types of spherical, conical, bowl and column according to the result of a 3D-MRI eyeball model. However, the external compression implant used in the conventional macular external pressure surgery cannot completely conform to the eyeball shape, which increases the difficulty of the surgical operation, so that complications such as iatrogenic damage to retina, sclera and extraocular muscles are likely to occur in the surgery, and symptoms such as exposure infection, strabismus, optic deformation, astigmatism and the like may also occur after the surgery due to poor fitting of the external compression implant. All current scleral external compression implants cannot realize quantitative jacking.
