Abstract
The present invention relates to nanoparticles, a preparation method thereof, a stone removal device, a magnetic target separation instrument and its application. The nanoparticles include a nanoparticle core made of magnetic materials, and a nanoparticle shell formed by attaching surface modifier monomers to the nanoparticle core with an initiator and/or a crosslinking agent. The prepared nanoparticles can wrap stones in ureter, and then small stones remaining in body can be removed quickly without damage from the body under the action of the magnetic target separation instrument. The stones can be drawn and moved without injuring ureteral wall, and meanwhile be disposed conveniently without easy shift.

A magnetic target separation instrument, comprising:
- a magnetic end,
- a connecting rod, and
- a handle;
- wherein a distal end of the connecting rod is connected to the magnetic end, a proximal end of the connecting rod is connected to the handle;
- wherein the connecting rod is made of a flexible material;
- wherein the magnetic end is a magnetic component;
- wherein the magnetic component is composed of a magnetic field source and a high-efficiency magnetically permeable end;
- wherein the high-efficiency magnetically permeable end splices a distal end of the magnetic field source;
- wherein the magnetic field source of the connecting rod is joined to the high-efficiency magnetically permeable end axially along the axis of the connecting rod, or the magnetic field source is coated by the high-efficiency magnetically permeable end,
- wherein the instrument has a relative movement between the magnetic field source and the high-efficiency magnetically permeable end;
- wherein the handle comprises a control push-rod which is connected to the magnetic field source within the magnetic end through an axial rigid rod or rigid tube;
- and
- wherein the axial rigid rod or rigid tube passes through a lumen of the connecting rod and is slidingly disposed in the connecting rod.
