Description

一种骨科手术用穿刺针
技术领域：
本实用新型涉及的是一种医疗用的手术器械，尤其是一种骨科手术用穿刺针。
背景技术：
在现有技术中，公知的技术是在用的穿刺针，现有的穿刺针在手术时由于刃口是突出在针管之外，当需要插入骨质时，刃口受到的阻力很大，能使针芯缩进针管内，给手术操作带来不便；而当穿刺完成需要将针芯退出时，由于骨质的密度较大，又夹紧针芯使针芯难以退出，严重时甚至可使针芯与针芯座脱离，给手术操作造成不必要的麻烦，使手术不能顺利进行，这是现有技术所存在的不足之处。
发明内容：
本实用新型的目的，就是针对现有技术所存在的不足，而提供一种骨科手术用穿刺针技术方案，该方案是在针芯座上固定有与空心螺栓配合的螺母，该螺母可用针芯座旋入空心螺栓，使针芯座与针管座固定，有利于穿刺针的插入和针芯的退出。
本方案是通过如下技术措施来实现的：该穿刺针包括有针管和固定针管的针管座，以及插入针管带有刃口的针芯和固定针芯的针芯座，在针管座上还有穿过针芯的空心螺栓，本方案的特点是在所述的针芯座上固定有一与空心螺栓配合的螺母，该螺母的轴线与所述针芯的轴线同轴。本方案具体的特点还有，所述的空心螺栓是鲁尔圆锥接头。所述的螺母与针芯和针芯座是一体结构。
本方案的有益效果可根据对上述方案的叙述得知，由于该方案中，在所述的针芯座上固定有一与空心螺栓配合的螺母，该螺母的轴线与所述针芯的轴线同轴。这一结构，在针芯座上的螺母可由针芯座的旋转将螺母旋入空心螺栓，使针芯座与针管座固定，当插入骨质时，由于螺母与空心螺栓的连接，使针芯座与针管座不能分离，有利于穿刺针的插入操作；而当需要退出针芯时，只要旋转针芯座使螺母与空心螺栓通过螺纹就很容易将针芯退出，操作极为方便，保证了手术的顺利进行。由此可见，本实用新型与现有技术相比，具有实质性特点和进步，其实施的有益效果也是显而易见的。
附图说明：
图1为本实用新型具体实施方式的结构示意图。
图2为图1的左视结构示意图。
图中，1为针管，2为针管座，3为螺母，4为针芯，5为空心螺栓，6为针芯座，7为刃口。
具体实施方式：
为能清楚说明本方案的技术特点，下面通过一个具体实施方式，并结合其附图，对本方案进行阐述。
通过附图可以看出，本方案的骨科手术用穿刺针，有针管1和固定针管1的针管座2，以及插入针管1带有刃口7的针芯4和固定针芯4的针芯座6，在针管座2上还有穿过针芯4的空心螺栓5，该空心螺栓5就是鲁尔圆锥接头。本方案是在所述的针芯座6上固定有一与空心螺栓5配合的螺母3，该螺母3与针芯4和针芯座6是一体结构，可以通过注塑、粘合或组装等方法成为一体结构。另外，所述螺母3的轴线与所述针芯4的轴线同轴。
