摘要： A lumen stent preform is provided using a plasma nitriding technology, a preparation method thereof, a method for preparing a lumen stent by using the preform, and a lumen stent obtained according to the method. The preform is manufactured by using pure iron or an iron alloy containing no strong nitrogen compound, has a hardness of 160-250HV0.05/10, and has a microstructure that is a deformed structure having a grain size scale greater than or equal to 9 or a deformed structure after cold machining. Alternatively, the preform is an iron alloy containing a strong nitrogen compound, and has a microstructure that is a deformed structure having a grain size scale greater than or equal to 9 or a deformed structure after cold machining. The lumen stem preform meets the requirements of a conventional stent for radial strength and plasticity, so that plasma nitriding is applicable to commercial preparation of a lumen stent.

摘要： The invention relates to a method of a magnetic material in stone removal, nanoparticles, a preparation method thereof and a stone removing device. Wherein, the magnetic material constitutes a nanoparticle core and a surface modifier monomer is attached to the nanoparticle core by an initiator and/or a crosslinking agent to form a nanoparticle shell. The prepared nanoparticles can surround stones in ureter, thereby, small stones remaining in body can be removed quickly without damage from the body under action of external magnetic field, that is, the stone can be drawn and moved without injuring ureteral wall, and the nanoparticles are placed conveniently without shift.
