Description

一种持骨钳
技术领域
本发明涉及医疗领域。
背景技术
持骨钳供骨科手术时夹持骨骼,起到固定、复位的作用,现在用于持骨钳一般都是只有两个钳杆,现有的具有以下几个缺点:一、钳头是无法弯折的,操作不方便;
二、现有的持骨钳主要是不锈钢材料制成,材料刚度不够,很难将破碎的髌骨夹紧固定牢固,使之在手术的过程中很容易出现夹住的骨头错位。
发明内容
本发明的目的在于:针对上述存在的问题,提供一种持骨钳,包括钳把和钳头,所述的钳把和钳头为可弯折的连接,所述的钳把为两个,两个钳把为铰接,所述的钳头铰接在钳把上,钳头和钳把的铰接轴与钳把之间的铰接轴垂直。
作为改进,所述的钳把的其中一个固定连接有一个固定杆,另一个钳把设有用于固定杆穿过的通道,固定杆为弧形,固定杆上设有摩擦块,所述的通道内铰接有一个固定扭,所述的固定扭设有一个尖部和摩擦块接触,并限制住固定杆,所述的固定扭还设有一个柄部用于操作固定扭绕着铰接轴顺时针运动。
现有的持骨钳钳头可以弯曲,提高了其通用性,并且紧固性高。
作为改进,所述的钳把和钳头的至少一个由碳化铬增强铝基复合材料制成。碳化铬增强铝基复合材料制备方法如下,步骤一:将炭黑、电解铬粉和铝粉末按照重量(1-2):5:100均匀混合;
步骤二:将步骤一后的物料出采用热压成型的方法,制成坯块。
步骤三:以10℃-50℃/min的加热速率加热坯块,加热到1400℃-1700℃,炭黑和铬粉反应生成碳化铬增强相;
步骤四:将上述元素进行增强元素均匀化热处理;
步骤五:将上述的处理后的复合材料进行热挤压;
步骤六:在再结晶温度以上进行热轧处理;
步骤七:将步骤六后的合金进行固溶处理。
其中在步骤1中炭黑和电解铬粉均可以采用常用的原料,其比例影响到增强相的粒径,为了使能够达到更加细小,炭黑和电解铬粉的质量比为(1-2):5。而增强相的粒径大小和基相的均匀程度可以通过调节加热温度来加入控制,本发明中的加热温度选择1400℃-1700℃,而加热速率的大小决定预热的快慢。
作为改进,所述的的电解铬粉的粒径为400目。
作为改进,所述的铝粉为超细铝粉,铝粉的精度为16~30μm。
作为改进,所述步骤三种的加热速率为20℃/min。
作为改进,所述的步骤四的热处理温度为600℃-800℃,热处理时间为20 min-100min,热处理在惰性气体下进行。
作为改进,所述步骤五的热挤压比为20:1-8:1之间,热挤压温度控制在500℃-700℃。
作为改进,所述步骤三的加热温度为1500℃-1600℃,进而将碳化铬的粒径控制在较优的水平,进一步的优选加热温度为1550℃。
作为改进,所述的步骤一中炭黑占增强相原料重量为25%-30%,在这种优选情况下,在原位生成过程当中得到的碳化铬更加的致密,达到纳米级别,并且能够充分分散到基体材料当中。
本发明公开的复合材料应用在铝合金3D打印领域,能够使得打印出来的产品性能达到锻件的效果,而现有的通常是达不到锻件的性能的。
本发明公开的铝基复合材料中碳化铬增强相可以达到纳米级别,制备的持骨钳轻薄便携,这种纳米陶瓷铝合金重量轻,且具有高刚度、高强度、抗疲劳、低膨胀、高阻尼、耐高温等特点,相比钛合金和高温合金,能够显著增强持骨钳的尺寸稳定性。
