Abstract: A device for separating an intestine subjected to a pulling force from a structure such as a fatty structure connected to the intestine by cutting includes a guide for guiding at least the intestine; and a cutting member connected to the guide for severing the structure in the vicinity of the intestine. The cutting member is adapted to sever the structure as closely as possible to the intestine. Further, a method includes fixing the structure, exerting a pulling force on the intestine, guiding the intestine and severing the structure in the vicinity of the intestine, wherein the combination of the structure and the intestine is guided prior to the cutting.
