Description

一种双极电凝钳的钳头绝缘装置
技术领域
本发明涉及医疗器械的领域，具体涉及一种双极电凝钳的钳头绝缘装置。
背景技术
双极电凝钳多用于脑外科、显微外科、五官科、妇产科以及手外科等较为精细的手术，双极电凝的安全性目前被人所认识，其使用范围逐渐扩大。其应用方法是：两极安全电流进入钳内，通过绝缘安装连接在两片钳头，通过双极的两个尖端向机体组织提供高频电能，使双极两端之间的组织脱水而凝固，达到止血的目的。现有技术的双极电凝钳种类多，其关键技术是两片钳头交叉安装，关节部位钳头销的绝缘装置是用高分子套管(塑料、橡胶等)进行绝缘，两片钳头之间也是用高分子隔板(塑料、橡胶等)进行绝缘。主要有以下缺陷：两片钳夹交叉安装磨损大；高分子套管和隔板是分体安装，在应用中由于两个钳头向机体组织提高频电能时，会产生高温，分体安装的套管和隔板会渗液而产生导电，使高分子材料产生软化变形或熔化。由于磨损大，所以目前的双极电凝钳几次使用就报废，满足不了理想的手术后效果。
发明内容
本发明的目的在于克服现有技术存在的不足，而提供一种双极电凝钳的钳头绝缘装置。
本发明的目的是通过如下技术方案来完成的：这种双极电凝钳的钳头绝缘装置，主要包括钳头A、钳头B、钳杆、绝缘件、钳头座和拉杆，拉杆穿过钳杆连接并驱动钳头A和钳头B，钳头A和钳头B通过绝缘件并采用销连接在钳头座上，钳头座与钳杆固定连接。所述钳头A上开有大销孔A和钳头座连接孔A，绝缘件上开有大销孔B和钳头座连接孔B，大销孔B和钳头座连接孔B和大销孔A和钳头座连接孔A分别两两配合使绝缘件安装在钳头A上，钳头座上开有钳头座连接孔C，钳头座连接孔A、钳头座连接孔B和钳头座连接孔C配合使钳头A连接到钳头座上。
所述钳头B上开有大销孔C和拉杆连接孔，大销孔C和大销孔A、大销孔B配合连接，拉杆连接孔连接到拉杆。
所述绝缘件的大销孔B后部两边有凸出两耳朵。
本发明的有益效果为：本发明结构设计合理，绝缘效果好，钳头磨损小，提高手术效率，可以有效提升产品的使用寿命，降低使用成品，增加产品的市场竞争力。
