Description
技术领域technical field
本发明属于医疗器械技术领域，涉及一种用于青光眼阀滤过泡部位的引流装置。The invention belongs to the technical field of medical devices, and relates to a drainage device used for the filtering bubble part of a glaucoma valve.
背景技术Background technique
青光眼（glaucoma）是一组以视乳头萎缩及凹陷、视野缺损及视力下降为共同特征的疾病，病理性眼压增高、视神经供血不足是其发病的原发危险因素，视神经对压力损害的耐受性也与青光眼的发生和发展有关。在房水循环途径中任何一环发生阻碍，均可导致眼压升高而引起的病理改变，但也有部分患者呈现正常眼压青光眼。青光眼是导致人类失明的三大致盲眼病之一，总人群发病率为1%，45岁以后为2%。临床上根据病因、房角、眼压描记等情况将青光眼分为原发性、继发性和先天性三大类。Glaucoma is a group of diseases characterized by atrophy and depression of the optic nerve head, visual field defect and vision loss. Sex is also associated with the development and progression of glaucoma. Any obstruction in the aqueous humor circulation pathway can lead to pathological changes caused by elevated intraocular pressure, but some patients also present with normal intraocular pressure glaucoma. Glaucoma is one of the three major blindness diseases that cause human blindness, with an incidence of 1% in the general population and 2% after the age of 45. Clinically, glaucoma is divided into three categories: primary, secondary and congenital according to the etiology, angle of the chamber, intraocular pressure and other conditions.
继发性青光眼是由于某些眼病或全身疾病干扰了正常的房水循环而引起的，如眼外伤所致的青光眼、新生血管性青光眼、虹膜睫状体炎继发性青光眼、糖皮质激素性青光眼等，其致病原因均较为明确。先天性青光眼是由于胚胎发育异常、房角结构先天变异所致。Secondary glaucoma is caused by some ocular or systemic diseases that interfere with normal aqueous humor circulation, such as glaucoma caused by ocular trauma, neovascular glaucoma, iridocyclitis secondary glaucoma, glucocorticoid-induced glaucoma etc., the cause of the disease is more clear. Congenital glaucoma is caused by abnormal embryonic development and congenital variation of angle structure.
青光眼是我国主要致盲原因之一，而且青光眼引起的视功能损伤是不可逆的，后果极为严重。一般来说青光眼是不能预防的，但早期发现、合理治疗，绝大多数患者可终生保持有用的视功能。因此，青光眼的防盲必须强调早期发现、早期诊断和早期治疗。治疗目的主要是降低眼压，减少眼组织损害，保护视功能。Glaucoma is one of the main causes of blindness in my country, and the visual impairment caused by glaucoma is irreversible, and the consequences are extremely serious. Generally speaking, glaucoma cannot be prevented, but with early detection and reasonable treatment, the vast majority of patients can maintain useful visual function throughout their lives. Therefore, blindness prevention of glaucoma must emphasize early detection, early diagnosis and early treatment. The main purpose of treatment is to reduce intraocular pressure, reduce ocular tissue damage, and protect visual function.
目前，现有技术中常见的治疗措施如下：At present, common treatment measures in the prior art are as follows:
（1）急性闭角型青光眼 急性发作时要局部频滴缩瞳剂，同时联合应用β-肾上腺能受体阻滞剂点眼，口服碳酸酐酶抑制剂等以迅速降低眼压。待眼压降低，炎症反应控制后进一步考虑做激光切除或其他抗青光眼手术。(1) Acute angle-closure glaucoma: In case of acute attack, local frequent drops of miotic, combined with β-adrenergic receptor blocker eye instillation, oral carbonic anhydrase inhibitor, etc., can rapidly reduce intraocular pressure. After the intraocular pressure is reduced and the inflammatory response is controlled, laser ablation or other anti-glaucoma surgery should be considered.
（2）慢性闭角型青光眼 初期可用缩瞳剂或β-肾上腺能受体阻滞剂局部治疗，若药物不能控制眼压或已有明显视神经损害者，需做滤过手术治疗。(2) Chronic angle-closure glaucoma can be treated locally with miotics or beta-adrenergic receptor blockers in the early stage. If the drugs cannot control the intraocular pressure or have obvious optic nerve damage, filtration surgery is required.
（3）原发性开角型青光眼 可先试用药物治疗，局部滴用1～2种眼药控制眼压在安全水平，并定期复查。药物治疗不理想可用激光治疗，或做滤过手术，目前最常用的滤过手术是小梁切除术。(3) For primary open-angle glaucoma, drug treatment can be tried first, and 1-2 kinds of eye drops can be used locally to control the intraocular pressure at a safe level, and regular review. If drug treatment is not ideal, laser treatment can be used, or filtering surgery can be done. The most commonly used filtering surgery is trabeculectomy.
（4）先天性青光眼 婴幼儿型以手术治疗为主，可通过房角切开术、小梁切开术治疗；青少年型早期可与开角青光眼相同，药物治疗不能控制时，可做小梁切开或小梁切除术。(4) Congenital glaucoma in infants and young children is mainly treated by surgery, which can be treated by goniectomy and trabeculotomy; early juvenile glaucoma can be the same as open angle glaucoma. Incision or trabeculectomy.
（5）继发性青光眼 治疗原发病同时，进行降眼压治疗，若眼压控制不满意，可针对继发原因做相应的抗青光眼手术治疗。(5) Secondary glaucoma: At the same time as the primary disease is treated, intraocular pressure lowering therapy is performed. If the intraocular pressure control is not satisfactory, corresponding anti-glaucoma surgery can be performed for the secondary cause.
