The invention provides a bi-component cross-linked composite material applied to urinary surgery. The cross-linked composite material comprises a first component and a second component, wherein the first component comprises an active group-terminated branched polylysine bonded sodium carboxymethyl cellulose recombinant high-molecular compound and an active group-terminated branched polylysine bonded three-arm polyethylene glycol carboxylic acid; or an active group-terminated branched polylysine bonded sodium carboxymethyl cellulose recombinant high-molecular compound and an active group-terminated branched polylysine bonded three-arm polyethylene glycol recombinant high-molecular compound; wherein the first component is provided with a branched chain, the tail end of the branched chain contains an active group, and the second component is an active group modified polydextrose biocompatible polysaccharide cross-linking agent and an active group modified low-molecular-weight carboxymethyl cellulose biocompatibl
