Abstract
本发明公开了一种增加手术闭合带宽度的方法，其钳头包括上电极、下电极；所述上电极和下电极的横截面均为曲线，且上电极和下电极在闭合时曲线的形状相互配合。本发明的在钳杆直径不变的情况下通过将上电极和下电极的横截面设置为相互配合的曲线，从而显著增加钳头夹持的宽度。当上下电极夹持组织或血管后，电流通过导线经过上极片的电极片‑‑组织或血管‑‑下电极返回形成回路；在曲面上喷涂有绝缘间隔，从而保证在咬合的过程中形成需要的间隙。
Description
技术领域
本发明涉及一种增加手术闭合带宽度的方法。
背景技术
微创手术目前应用的范围越来越广，很多的病例医院都开始采用微创手术代替传统的手术术式，配套微创手术的医疗器械尺寸也变得越来越小，导致器械的钳头夹持部分越来越窄，而对于闭合大血管等跟闭合带宽度正相关的医疗器械，过窄的钳头闭合带对血管的闭合效果变得非常脆弱，容易导致出血和二次出血的手术问题。
发明内容
为解决现有技术中钳头夹持部分越来越窄,过窄的钳头闭合带对血管的闭合效果变得非常脆弱的缺点，在钳杆直径不变的情况下显著增加钳头夹持的宽度。
一种增加手术闭合带宽度的方法，其特征在于，其钳头包括上电极、下电极；所述上电极和下电极的横截面均为曲线，且上电极和下电极在闭合时曲线的形状相互配合。
进一步的，所述上电极包含上电极座和电极片，所述上电极座和电极片采用注塑包胶的方式连接。
进一步的，电源通过导线连接电极片，所述上电极座和电极片之间保持绝缘。
进一步的，所述下电极采用整体金属加工，也可采用所述上电极分体方式，并与电源连接形成回路。
进一步的，上电极和下电极的横截面为波浪线、弧线或者波浪线与弧线的组合。
进一步的，在上电极或下电极的表面爆炸喷涂有若干高度一致的绝缘间隔点。优选的，所述的间隔点为陶瓷。
本发明的在钳杆直径不变的情况下通过将上电极和下电极的横截面设置为相互配合的曲线，从而显著增加钳头夹持的宽度。当上下电极夹持组织或血管后，电流通过导线经过上极片的电极片-------组织或血管-------下电极返回形成回路；在曲面上喷涂有绝缘间隔，从而保证在咬合的过程中形成需要的间隙。
