Abstract

Two new disposable cannulas for internal drainage of subretinal fluid are described in this article. We describe a curved and a straight version consisting of plastic hubs, 20 gauge proximal and 25 gauge distal stainless steel hypodermic tubing, and soft and flexible silicone tubing overmounts. Both these cannulas facilitate atraumatic drainage of subretinal fluid through pre-existing retinal holes and tears or through a retinotomy performed during vitreoretinal microsurgery.

摘要

本文介绍了两种用于视网膜下液内引流的新型一次性套管。我们描述了一种弯曲型和一种直型套管,它们由塑料接头、20号近端和25号远端不锈钢皮下注射管以及柔软灵活的硅胶管套组成。这两种套管都有助于通过现有的视网膜裂孔和撕裂或通过玻璃体视网膜显微手术中进行的视网膜切开术,实现视网膜下液的无创伤引流。
