| description | The invention belongs to the technical field of medical adhesives and medical instruments, and particularly relates to a medical tissue sealant composition, a sealant and a preparation method and application of the sealant. The medical tissue sealant composition comprises a first component and a second component, wherein the first component is a polymer containing at least one active group of acid anhydride, aldehyde group, succinimide group and maleimide group; the second component is a polymer containing at least one active group of sulfydryl, amino, methylenimine, sulfenyl salt and amino salt; and the molar ratio of the active group of the first component to the active group of the second component is 1: 10-20: 1. The medical tissue sealant composition is directly subjected to a cross-linking reaction in a neutral solution to generate a hydrogel sealant, a catalyst or a cross-linking agent and the like are not needed, the gel forming time is short, for example, the gel forming time of a wound surface does |
