Description

一次性颈部穿刺专用针
技术领域
本发明涉及一种医疗器械,特别涉及一种一次性颈部穿刺专用针。
背景技术
目前,颈部穿刺是先采用细针进行试穿,试穿成功后拔出细针,按细针针孔和穿入深度再二次穿入粗针,粗针穿刺成功后进行余下的穿刺操作,这种二次穿刺的操作步骤繁琐,成功率有限,患者常常会因为多次穿刺造成颈部损伤和出血,以及由损伤和出血引起的水肿等并发症。
发明内容
本发明的目的是提供一种一次性颈部穿刺专用针,该一次性颈部穿刺专用针减轻了患者在颈部穿刺过程中的痛苦,挺高了颈部穿刺的成功率。
本发明是由内部细针、外部粗针和限位索组成,其中内部细针和外部粗针均为金属材料制造的空心针,内部细针比外部粗针长3~5cm,内部细针穿套在外部粗针内且可自由滑动,内部细针针座和外部粗针针座均采用塑料材料制造,内部细针和外部粗针之间设有塑料材质的限位索,限位索的两端分别与内部细针针座和外部粗针针座相连,限位索与内部细针针座和外部粗针针座连接处柔软,中间略硬。
本发明的工作原理及过程:使用时先将外部粗针向内部细针的针座方向拉回,露出内部细针的针尖,用内部细针进行颈部穿刺操作,内部细针试穿成功后,保持内部细针不动,推动外部粗针向前滑动至限位索限制位置,内部细针的针尖和外部粗针的针尖刚好对齐,并保持相对位置不变,用剪刀剪断限位索,拔出内部细针后,就可进行颈部穿刺余下的操作。
本发明的有益效果:操作简便、成功率高,并且在一定程度上减轻了患者进行颈部穿刺的痛苦。
附图说明
图1为本发明之实施例使用前的剖视图。
图2为本发明之实施例外部粗针拉回后的剖视图。
图3为图1中的A处放大示意图。
具体实施方式
请参阅图1、图2和图3所示,为发明的实施例,是由内部细针1、外部粗针2和限位索3组成,其中内部细针1和外部粗针2均为金属材料制造的空心针,内部细针1比外部粗针2长3~5cm,内部细针1穿套在外部粗针2内且可自由滑动,内部细针针座12和外部粗针针座22均采用塑料材料制造,内部细针1和外部粗针2之间设有塑料材质的限位索3,限位索3的两端分别与内部细针针座12和外部粗针针座22相连,限位索3与内部细针针座12和外部粗针针座22连接处柔软,中间略硬。
本实施例的工作原理及过程:使用时先将外部粗针2向内部细针1的针座12方向拉回,露出内部细针1的针尖11,用内部细针1进行颈部穿刺操作,内部细针1试穿成功后,保持内部细针1不动,推动外部粗针2向前滑动至限位索3限制位置,内部细针1的针尖11和外部粗针2的针尖21刚好对齐,并保持相对位置不变,用剪刀剪断限位索3,拔出内部细针1后,就可进行颈部穿刺余下的操作。
