The invention relates to an anal fistula plug which is insusceptible to dropping. The anal fistula plug comprises a circular table body implanting section, wherein the large end face of the implanting section is connected with one end of a plug body section; the other end of the plug body section is connected with a bottom surface of a cylindrical stitching area; the plug body section is formed by connecting more than two oblate spheroids; and the stitching area and the plug body section are made of a small intestinal submucosa or an allogenic biological material. According to the anal fistula plug, a plug body consists of a plurality of oblate spheroids, and the axial self-balancing of uniformly-distributed acting force to which the single oblate spheroid is subjected can be realized, so axial force generated by deformation stretching is generated on the integral plug body section only, and is balanced with 'rectal resting pressure' which acts on the large-end face side of the implanting section to avoid operation failure caused by the dropping of the implanting section. Numerical simulation indicates that the axial component force of the anal fistula plug under weight pressure can be reduced greatly, so that the anal fistula plug is prevented from dropping.

The invention provides an anal fistula biological suppository and a preparation method thereof.
