Porous separation needle of micro - passivity

In the porous separation needle of micro - passivity mainly used ophthalmology micrurgy, need injection viscoelastic agent to maintain the eyeball shape and separate eyeball inside portion adhesion tissue. What inject the viscoelastic agent use at present is ordinary microinjection needle, and the syringe needle top is crew cut, haplopore, causes tissue lesion easily, and viscoelastic agent separation direction is single moreover. Porous separation needle of micro - passivity, the syringe needle position is the hemispheroid, is equipped with an injection orifice on the summit of hemispheroid,and the peripheral evenly distributed in bottom of hemispheroid establishes four injection orifices, forms three -dimensional injection effect, can guarantee to inject liquid like this and pack uniformly fast and organize space and blunt separation to organize, and spherical syringe needle can not damage the tissue in addition. 显微钝性多孔分离针主要用于眼科显微手术中，需要注射粘弹剂维持眼球形状和分离眼球内部粘连组织。目前注射粘弹剂使用的是普通显微注射针，针头顶端为平头、单孔，容易造成组织损伤，而且粘弹剂分离方向单
