The present application discloses a surgical apparatus for aneurysms comprising: a stent, a delivery guide wire, an introducer sheath and a microcatheter, wherein: the stent is a self-expanding stent； the delivery guide wire outside of which the stent is restrained to is provided in a lumen of the introducer sheath； the introducer sheather is connected with the microcatheter, with lumens communicating, to form a passageway through which the delivery guide wire and the stent are delivered into a human body. The surgical apparatus for aneurysms provided in the examples of the present application is able to deliver and release the stent which has high density and is super soft to a vascular lesion. A lattice structure of the stent is of high coverage at the vascular lesion such that the stent released into the vessel produces the same effects as healing of parent vessel, and thus improves the treatment of vascular aneurysms.
