一种内路实施的施莱姆氏管手术治疗系统 An in-channel embodiment of Schlemm & apos venturi surgery system

技术领域 FIELD

[0001]本发明涉及一种微创青光眼手术治疗系统,尤其涉及一种内路实施的施莱姆氏管手术治疗系统。 [0001] The present invention relates to a minimally invasive treatment of glaucoma surgery systems, particularly to surgical treatment of Schlemm & apos venturi passage within a system embodiment.

背景技术 Background technique

[0002]青光眼是一种常见的眼科疾病,是全球第一位不可治愈的致盲眼病,中国的青光眼患者占全球之首。 [0002] Glaucoma is a common eye disease, is the world's first untreatable blindness, glaucoma patients accounted for China in the world. 目前,唯一有效的青光眼治疗方法为降低眼压。 Currently, the only effective treatment for glaucoma to reduce intraocular pressure. 常用方法为药物治疗和手术治疗。 The method commonly used for medical treatment and surgery. 但很多患者在最大用药量的情况下眼压仍然难以控制,也有患者难以接受药物的副作用,须进行手术治疗。 But many patients still difficult to control intraocular pressure at maximum dosage, but also in patients with unacceptable side effects of drugs, should be treated with surgery.

[0003]传统的手术方式是小梁切除术。 [0003] The traditional surgical approach is trabeculectomy. 该术式属于“房水短路”手术,即将房水从眼内直接通过巩膜壁上的造瘘口引流到眼球外(结膜下),术中及围手术期并发症高。 The procedure in "aqueous humor short" operation, i.e. aqueous humor from the eye through the sclera stoma directly drained into the outer wall of the eye (subconjunctival), high intraoperative and perioperative complications. 即使手术成功,手术形成的功能滤过泡不但永久地改变了眼表的正常结构和眼的房水生理循环,还可导致如滤过泡炎、薄壁滤过泡等诸多严重滤过泡相关并发症。 Even if the operation is successful, a surgically created bleb function not only permanently altered physiological aqueous humor circulation and the normal structures of the ocular surface of the eye, also result in inflammation such as blebs, thin-walled, and many serious bleb blebs associated complication.

[0004]近年来,国际国内开始采用青光眼微创手术治疗青光眼,收到了较好的效果。 [0004] In recent years, domestic and international glaucoma began to use minimally invasive surgical treatment of glaucoma, received good results. 粘小管成形术(Canaloplasty)是其中的代表,也是唯一解除集液管阻滞的微创青光眼手术,这一术式可广泛地用于开角型青光眼患者。 Small adhesive angioplasty (Canaloplasty) which is representative of a minimally invasive glaucoma surgery is the only lifting the collecting channel block, the surgical procedures can be widely used in patients with open-angle glaucoma. 手术利用特制的微导管将一根聚丙烯缝线36〇度贯穿施莱姆氏管(SchleranTs Canal),缝线两端打结,保持张力可以恢复施莱姆氏管的引流,手术并发症少,是一种安全有效的术式。 Operation using a special microcatheter through a polypropylene suture of Schlemm & apos 36〇 venturi (SchleranTs Canal), both ends of the suture knot to maintain the tension to restore the drainage Schlemm & apos venturi, less complication It is a safe and effective surgical procedures. 2015年出现了一种新的青光眼微创手术―内路粘小管成形术(AB-interno Canaloplasty),通过透明角膜微切口,使用特制的微导管36〇度扩张施莱姆氏管,具有粘小管成形术(Canaloplasty)的优点重建了房水天然排除途径, 还保持了结膜形态,安全性更高,手术创伤更小,术后恢复更快,是更为安全有效的治疗方式。 2015 there is a new minimally invasive surgery of glaucoma - the passage of small stick angioplasty (AB-interno Canaloplasty), micro-incision through the transparent cornea, using a special microcatheter 36〇 expansion of Schlemm & apos venturi tube having a small viscosity the advantages of angioplasty (Canaloplasty) reconstruction of the aqueous humor exclude natural way, but also to maintain the conjunctiva shape, more secure, less invasive surgery, faster recovery after surgery is safer and more effective treatment. 但是内路粘小管成形术目前采用缝线36〇度贯穿施莱姆氏管打结的方式,但是缝线形成的张力有可能随时间发生变化,造成施莱姆氏管再次塌陷,阻碍房水排出,因此,发明一种更为稳定有效的内路施莱姆氏管微创治疗系统则显得很有必要。 However, the passage of small stick angioplasty currently used 36〇 of suture knotted through Schlemm & apos venturi manner, but the tension of the suture formed may change over time, resulting in collapse of Schlemm & apos venturi again, aqueous hindered discharge, so a more stable and effective 内路施莱姆 invention venturi system is minimally invasive treatment becomes necessary. tGMS]发明专利内容、本发明要解决的问题是提供一种内路实施的施莱姆氏管手术治疗系统,用于内路实施的施莱姆氏管的手术中,以微创的手术方式降低眼压,治疗青光眼。 TGMS] Patent summary, the present invention is to solve is to provide a path within the Schlemm & apos embodiment venturi surgery system for operation within Schlemm & apos venturi passage in the embodiment, a minimally invasive surgical approach reduce intraocular pressure, glaucoma. 本发明给医生提供了一种简单易操作的手术方式,有利于推广应用。 The present invention provides a surgical approach to the doctors a simple and easy to operate, help to promote the application.
