Research on the Operational Techniques and Thread Development Status of Acupoint Catgut Embedding

Abstract

Acupoint catgut embedding therapy is an innovative treatment that integrates the traditional acupuncture concept of "deep insertion and prolonged retention" with modern material science. By implanting absorbable threads into acupoints, it provides continuous physical and biochemical stimulation during in vivo degradation, thereby achieving long-term regulation of meridians and Qi-blood. Since its clinical introduction in the latter half of the 20th century, the technique has evolved from using natural catgut to various synthetic absorbable sutures. In 2019, the China Association of Acupuncture-Moxibustion issued the group standard *Technical Operation Standard for Acupoint Catgut Embedding* (T/CAAM 013-2019), establishing a systematic framework for standardized practice. This review aims to summarize the key operational techniques, material development, and clinical application status of acupoint catgut embedding.
