Description

虹膜固定装置及虹膜固定方法 Iris and the iris fixation means fixing method

技术领域 FIELD

[0001] 本发明属于医疗器械领域,具体涉及一种虹膜固定装置及虹膜固定方法。 [0001] The present invention belongs to the field of medical devices, particularly to a fixing apparatus and an iris iris fixing method.

背景技术 Background technique

[0002] 在眼科诊断和治疗中,需要充分的操作视野,尤其对于白内障摘除术或是涉及眼底的玻璃体视网膜手术等眼科操作来说,散大的瞳孔和稳定的虹膜是提供充分的手术视野,顺利完成眼科治疗的必要保证,但是,对于伴有虹膜睫状体炎、青光眼、糖尿病等疾病的患者常常会出现病理性小瞳孔或虹膜粘连,难以用药物散大瞳孔;对于虹膜松弛综合症的患者,虹膜在前房内飘动,影响手术操作,易误伤眼内正常组织,引起严重的并发症,影响治疗的临床疗效。 [0002] In ophthalmologic diagnosis and treatment, the need for adequate operation of the field of view, in particular, relates to cataract surgery or vitreoretinal surgery fundus ophthalmic procedure, the dilated pupil and iris to provide sufficient stability of the surgical field, necessary to ensure the successful completion of ophthalmic treatments, however, accompanied by iridocyclitis for patients with glaucoma, diabetes and other diseases often appear pathologic small pupil or iris adhesions, difficult dilated pupil with drugs; for relaxation iris syndrome patients, anterior chamber iris flutter, affect the surgical operation, easy to accidentally injure the eye of normal tissue, causing serious complications, the clinical efficacy of treatment effects.

[0003]目前用于扩大瞳孔和固定虹膜的方法主要有:向前房内注入粘弹剂直接扩大瞳孔、虹膜张力切开、多点虹膜括约肌剪开等,现有的方法扩大瞳孔和固定虹膜的作用有限,并且易引起出血和炎症反应,导致瞳孔欠圆和瞳孔括约肌撕裂,造成术后瞳孔形状不规则或呈无张力状态。 [0003] Current methods for the expansion of the pupil and the iris fixation are: anterior chamber injection of viscoelastic direct expansion pupil, iris tension cut, cut like multi iris sphincter, the conventional method was expanded and fixed iris pupil a limited effect and can lead to bleeding and inflammation, resulting in less round pupil and pupil sphincter tear, resulting in an irregular shape or in pupil after tension-free state.

[0004] 也有人采用弹性虹膜拉钩扩大瞳孔,但虹膜拉钩也存在以下不足之处:1、虹膜拉钩对虹膜边缘的单点牵拉,拉开的范围有限,而且拉钩必须分别准确定位于相互垂直的经线上,这样才能形成较理想的瞳孔形状,否则将呈长方形、梯形等扭曲的形状,造成不必要的瞳孔括约肌损伤,无法有效扩大手术视野。 [0004] It was also employed to expand the resilient iris hook pupil, iris hook but there are the following shortcomings: 1, single point iris hook pulls the edge of the iris, opened limited range, and are accurately positioned in the retractor to be perpendicular to each other by line, so as to form ideal pupil shape, or will show a rectangle, a trapezoid distortion, resulting in unnecessary the pupil sphincter injury, can not effectively expand the surgical field. 2、需要在不同方位的角膜缘切口放置3-4个虹膜拉钩甚至更多才能完成,既延长了手术的时间又增加了手术切口源性的损伤。 2, need to be placed 3-4 iris retractors or more to complete, only to extend the time of surgery has increased the damage of endogenous surgical incision in the limbus incision in different directions.

发明内容 SUMMARY

[0005] 基于此,本发明在于克服现有技术的缺陷,提供一种虹膜固定装置及虹膜固定方法,本发明可以有效的扩大瞳孔,减少手术过程中对眼部组织的损伤。 [0005] Based on this, the present invention is to overcome the drawbacks of the prior art to provide an apparatus and iris fixed iris fixation methods, the present invention can effectively expand the pupil during surgery to reduce injury to the eye tissue.
