Description

毛细管
技术领域
本发明涉及微创医疗技术领域汽化电切镜等电切环绝缘用毛细管。
背景技术
微创医疗技术对设备的小型化、微型化提出了更高要求。而电外科手术器械汽化电切镜等用的电切环对电极的绝缘强度和机械强度提出很高要求：机械强度足够高，安装时能够承受一定外力而不能折断、破裂；电气绝缘强度足够高，壁厚0.20mm的毛细管要能承受直流3000V、3秒电压而不击穿。尺寸要小巧，满足紧凑空间狭小条件。苛刻的技术要求对电切环用绝缘材料的选择提出了挑战：外径尺寸要小，以便插入很细的电极支撑体；内径要大，方便穿入电极和绝缘胶。机械强度足够高：能够承受一定外力而不损坏。电气绝缘强度足够高：承受直流高电压而不击穿。
发明内容
本发明要解决的技术问题是提供一种尺寸小巧、机械强度高、电气绝缘高的电切环电极等用毛细管。
为解决上述技术问题，本发明的技术方案是：使用细晶粒纳微粒径高纯陶瓷粉，对细晶粒纳微粒径高纯陶瓷粉增韧改性提高机械性能。细晶粒超细陶瓷份加入黏合剂增塑剂溶剂制成柔软的坯料，放进液压挤出机挤成坯体，干燥，烧结。对烧成后的毛细管切断，精密研磨里孔，以里孔定位在同心磨上磨削外圆，保证毛细管同心，壁厚一致。
该技术方案制成的毛细管，同心度好，机械强度高，电气绝缘强度高，方便电切环的制造，延长电切环使用寿命，降低医生手术强度，患者手术体验更佳。
