Description
技术领域
本发明属于医疗器材领域,具体是一种电凝钳。
背景技术
腹腔镜微创手术是现在越来越使用广泛的一种手术,具有手术效率高,对人体损
伤小等优点,减少病人恢复的时间。在腹腔镜微创手术中经常要使用到电凝钳进行灼烧止血,具有非常好的效果,在灼烧止血的过程当中,需要用钳头夹紧组织。而在夹紧组织的时候,由于钳头、拉动装置等都是刚性的,有时会时钳头对组织夹持过紧,损伤夹持的组织。
发明内容
本发明的目的在于:针对上述存在的问题,提供一种腹腔镜微创手术电凝钳,包
括:枪把,所述的枪把用来外科手术人员用手进行操作,所述的枪把设有扳机;
钳管,所述的钳管连接枪把和钳头,所述的钳管为中空结构;拉杆,拉杆位于钳管内部,并将枪把的动力传输到钳头,控制钳头的开闭,所述的拉杆包括第一拉杆以及与第一拉杆联动的第二拉杆,所述的第一拉杆和第二拉杆通过第一弹簧连接,第一拉杆和第二拉杆之间设有卡位装置,当第一拉杆和第二拉杆卡位连接的时候,第一弹簧处于拉紧状态 ,第一拉杆和第二拉杆可以沿着卡位装置沿着钳管轴向方向移动。钳头,所述的钳头连接钳管,并和拉杆联动,钳头和导线连接。
作为改进,所述的第一拉杆包括有一个沿着轴向方向凸出的凸部,凸部末端设有
第一弹簧第二拉杆沿着轴向方向设有凹部,凹部深度大于凸部的长度,第一弹簧的一端和凸部末端连接,另一端和凹部底部连接,当凸部完成伸入到凹部中,第一弹簧位于拉紧状态。
当第一弹簧处于拉紧状态的时候,这个时候扣扳机,第一拉杆和第二拉杆不会相
对移动,可以正常控制钳头的开闭,而当钳头闭合或者即将闭合的时候,拉杆传动的力会增大,这个时候弹簧所受的力会大于开始拉紧状态的力,第一拉杆和第二拉杆会相互移动,这个时候可以防止钳头过紧夹持组织,阻止了对组织的损伤。第一弹簧的初始拉紧状态以及弹簧的参数等,可以钳头的开闭需要进行少数后的几次实验就可以设置,而凹部和第二拉杆可以是一体式成型,也可以是固定连接,可以在将第一弹簧按照在第二拉杆上后再安装凹部。
在一些实施方式中,第一拉杆、第二拉杆均为中空结构,和钳头连接的导线从中空穿过,导线也可以从第一弹簧中间穿过,导线也可以从侧面等方向穿过。
作为改进,所述的第二拉杆上设有一个固定座,第二拉杆上套结有第二弹簧,第二弹簧的一端连接固定座或者被固定座卡住,另一端被钳管或者枪把固定。这种方式设置的目的有二:其一,当手松紧扳机的时候,钳头会自动回到打开状态,不需要手动打开;其二,拉扳机的时候,也会给人手一个方向的力,防止钳头闭合过紧,保护组织。本发明的设计,使用的时候,可以放置钳头过紧夹住组织,能够 有效的防止人体组织被损伤。
其中,本发明钳头导体部分优选采用钛合金材料制备,采用钛合金材料具备耐热
性、强度、塑性、韧性、生物相容性均较好,但是现有的钛合金抗氧化性不足,主要在于钛合金金属杂质元素、如氧较多,并且耐磨性不足,在持针器方面使用有一定的不足。为了解决上述问题,本发明同时公开了一种钛合金材料,所述的钛合金采用真空熔融的方式,其中真空熔融的方式如下:
步骤一、选用钛原料,放入熔炉中;
步骤二、打开电源、通入氩气,保持真空度为15Kpa-40Kpa,加热到1700℃-1800℃进行
熔融,根据熔体变化适当调整功率使得气泡稳定;
步骤三、当没有气泡生成的时候,通入氩气,保持真空度为50 Kpa -100 Kpa,此时加入合金元素,所述的合金相对于100份钛,具体为0 .001-0 .05份锂、0 .01-0 .05份锌、0.001-0 .05份铬、0 .001-0 .05份镧和0 .001-0 .05份铈。其中加入合金的元素按照锂、铬、镧、铈的顺利,这样可以减少合金元素的挥发流失, 合金元素分别为100份钛,0 .04份锂、0 .03份锌、0 .04份铬、0 .02份镧和0 .02份铈。
步骤四、待熔融10min-50min后并在底部通过氮气搅拌,进行冷却,冷却的时候用超声波辐照结晶,超声波功率为M*(20-150)W,M为熔融合金质量单位为kg,其中通过超声波辐照可以提高钛合金晶粒致密性,使得耐热性、强度得到很大提高,其中实验发现,通入氮气可以充分搅拌,使结晶材料更加的均匀。
步骤五、铸锭,后处理加工。
在本发明中经过实验对比,采用上述方法,可以大大的提高钛合金的抗氧化性、耐磨性等性能,能够使得钛合金制备的持针器应用在微创手术领域,让持针器安全的进入人体内进行相应的手术操作,并且本发明公开的钛合金材料具有优异的电导率性能,在医疗上具有广泛的使用前景。
