A medical holding apparatus provided with an anchor member composed of a tying-up portion to be tied up to an intracorporeal tissue and a first connection portion; and a locking member composed of a holding portion for holding another intracorporeal tissue, a medical instrument or a drug and a second connection portion, in which the first connection portion and the second connection portion can be detachably connected to each other. A method of using the medical holding apparatus comprising steps of inserting the anchor member into a lumen of a cylindrical member; bringing the cylindrical member distal end close to a predetermined intracorporeal tissue surface; pushing the anchor member from the cylindrical member proximal end side so as to project the anchor member out of the cylindrical member distal end and tying up the anchor member to the intracorporeal tissue; holding another intracorporeal tissue, the medical instrument or the drug by the holding portion of the locking member; and connecting the second connection portion to the first connection portion by a magnetic force and the like.
