The invention discloses a non-granulation sodium hyaluronate linear cross-linking modification process method. The cross-linked sodium hyaluronate gel is obtained by cross-linking reaction, and finally the cross-linked sodium hyaluronate gel is placed in a non-cross-linked sodium hyaluronate solution containing lidocaine, and the cross-linked modified hyaluronate is obtained by swelling at high temperature Sodium Gel. The sodium hyaluronate gel is uniform and viscous and fluid without granulation. It not only has the shape and clinical efficacy of non-cross-linked sodium hyaluronate, but also has the efficacy of filling and maintaining cross-linked products for a long time. Lido is added during the preparation process. Caine can relieve pain and improve patient comfort. It can be used in many fields such as anti-adhesion after abdominal surgery, joint cavity lubrication, medical beauty wrinkle removal, scar repair, oral filling, and women's fallopian tube anti-adhesion. |
