Description
技术领域technical field
本发明涉及一种眼内异物取出器，具体是一种多功能眼内异物取出器。The invention relates to an intraocular foreign body extractor, in particular to a multifunctional intraocular foreign body extractor.
背景技术Background technique
眼内异物伤是视力损伤的重要原因之一，尽管随着玻璃体视网膜手术的发展，眼外伤的诊疗水平得到较大的提高。目前，临床中对于有棱角(非光滑)的眼内异物大都通过玻璃体切除手术，在显微镜直视下采用异物镊(爪)抓取后轻松通过穿刺口或角巩膜缘隧道切口取出；对于磁性异物可以通过磁铁直接吸出或磁棒接力法吸出。但对于球形或者光滑的眼内异物，以及其它不宜抓取的异物，异物镊(爪)不能抓取异物造成眼内异物的取出困难。而眼内异物长期不取出或处理不当，易导致失明、眼球萎缩等严重后果。Intraocular foreign body injury is one of the important causes of visual impairment, although with the development of vitreoretinal surgery, the level of diagnosis and treatment of ocular trauma has been greatly improved. At present, most of the angular (non-smooth) intraocular foreign bodies are treated by vitrectomy in clinical practice, and they are easily removed through the puncture port or corneoscleral limbal tunnel incision after being grasped by foreign body forceps (claws) under direct vision of the microscope; for magnetic foreign bodies It can be sucked out directly by a magnet or by a magnetic rod relay method. But for spherical or smooth intraocular foreign bodies, and other foreign bodies that are not suitable for grasping, foreign body tweezers (claws) cannot grasp foreign bodies and cause difficulty in taking out intraocular foreign bodies. If the foreign body in the eye is not removed or handled improperly for a long time, it will easily lead to serious consequences such as blindness and eyeball atrophy.
