The invention relates to a small corneal limbus transplant collector for a living body. The small corneal limbus transplant collector for the living body comprises an upper forceps handle, a lower forceps handle, a cutter ring and a cutter plate; a first hollow structure is arranged at the front end of the upper forceps handle, and a second hollow structure is arranged at the front end of the lower forceps handle; a first bulge embedded with the first hollow structure is arranged at the tail end of the cutter ring; a second bulge embedded with the second hollow structure is arranged at the tail end of the cutter plate; the head end of the cutter ring is of an annular hollow structure, and the head end of the cutter plate is an annular solid piece. The small corneal limbus transplant collector has the advantages that the structure is simple, operation is easy and convenient, the small corneal limbus transplant collector is designed according to the morphological characteristics of the human cornea, corneal limbus tissue can be accurately cut, an operator can select different corneal limbus areas for multi-site collection, scar repair caused by the too large cutting area in a traditional operation is avoided, meanwhile, the suite can be automatically replaced and freely matched, the area of a required transplantation body is adjusted, the operation difficulty and time are effectively reduced, and popularization is easy.
