Abstract

本发明公开了一种覆膜式四爪异物钳,具有固定把手和滑动手柄,滑动手柄前端设有外鞘管,外鞘管内设有相同的5根操作丝,操作丝前端外展部分覆有薄而柔软的透明硅橡胶膜。使用时向下推动滑动手柄,操作丝伸出外鞘管,并呈外展型;向上提拉滑动手柄,操作丝收回鞘管内。本发明具有操作简单,灵活方便、节时省力、抓取牢固等特点,可广泛用于内镜下异物取出术,使治疗更快捷,最大程度的减轻患者的痛苦,同时大大降低了并发症的发生率。

Description

覆膜式四爪异物钳
技术领域
本发明涉及医疗用品,直接涉及上消化道治疗覆膜式四爪异物钳。 
背景技术
在治疗上消化道异物时,我们通常会采用五爪型异物钳取出术。对于骨类等硬度适中的异物,我们现用的异物钳常可手到擒来,但对于肉类或球类异物时,却因为易碎或光滑易滑落而无法一次性取出,通常要分3次甚至更多次才能完成,这大大增加了患者的痛苦,也降低了工作效率。 
发明内容
本发明的目的就是要提供一种改进的覆膜式四爪异物钳,它能在抓取较小、易滑脱的异物时完整、一次性顺利的取出。 
本发明的目的是这样实现的:具有固定把手和滑动手柄,滑动手柄前端设有外鞘管,外鞘管内设有相同的5根操作丝,操作丝前端外展部分覆有薄而柔软的透明硅橡胶膜,提拉滑动手柄,操作丝可收回外鞘管内。
本发明由于设置了橡胶膜,在抓取易碎的异物时可防止操作丝割碎异物,带膜的爪型钳口可完全包裹异物,使其一次性顺利取出;在抓取较小、易滑脱的异物时,其膜同样起到包裹的作用。
附图说明    附图是本发明的结构示意图,下面结合附图对本发明作进一步说明。
具体实施方式    附图示出了本发明覆膜式四爪异物钳的结构。具有固定把手1和滑动手柄2,滑动手柄2前端设有外鞘管3,外鞘管3内设有相同的5根操作丝4,操作丝4前端外展部分覆有薄而柔软的透明硅橡胶膜5,其特征是:提拉滑动手柄2,操作丝4可收回外鞘管3内。使用时常规进镜至见异物,由内镜活检孔插入异物钳至插入部先端在内镜视野中出现,向下推送滑动手柄2使操作丝4完全伸出外鞘管3外,操作丝4外展,抓紧异物后向上提拉滑动手柄2,操作丝4收紧,连同胃镜一起退出体外。本发明具有操作简单,灵活方便、节时省力、抓取牢固等特点,可广泛用于内镜下异物取出术,使治疗更快捷,最大程度的减轻患者的痛苦,同时大大降低了并发症的发生率。
