Preparation method for solid implantation catgut for treating spinal diseases

The invention relates to a preparation method for a solid implantation catgut for treating spinal diseases, which is characterized by comprising the following steps of: extracting active ingredients from Chinese medicinal compositions such as musk, rosewood heart wood, frankincense, sappan wood, storax, costustoot, root of red-rooted salvia and the like to obtain concentrated solution of the Chinese medicinal compositions; and adding hyaluronidase into the concentrated solution of the Chinese medicinal compositions to obtain mixed soak solution, and soaking a catgut with the length of between 2.5 and 3.5 centimeters in the mixed soak solution for 10 to 20 days to obtain the solid implantation catgut. The solid implantation catgut for treating spinal diseases can be used for being implanted into an ashi point or acupuncture points to treat spinal diseases. By the solid implantation catgut, medicaments can enter in bodies at constant speed within long time to maintain constant and effective blood concentration, so the phenomenon of the peak valley of the blood concentration due to other administration modes is avoided, adverse reactions can be reduced, and the double effects of the medicaments and the acupuncture points are expressed simultaneously to achieve the optimum pharmacological effect.
