Abstract

The invention relates to a 3D printing intravascular stent conveyor, and belongs to the technical field of devices for providing openings for a human body tubular structure or preventing collapse. Theconveyor comprises a conveyor body. The conveyor body comprises a shell, a driving mechanism and a throwing mechanism. The shell is a cylindrical thin shell with one open end and one closed end. Theopen end of the shell is provided with a stent storage chamber for containing an intravascular stent, the closed end of the shell is provided with a driving mechanism storage chamber for containing the driving mechanism, the throwing mechanism is arranged between the stent storage chamber and the driving mechanism storage chamber, the driving mechanism comprises a two-way driving pump and a driving motor, and the throwing mechanism comprises a multi-stage hydraulic cylinder and a pushing block which are coaxially arranged. Due to the creative design, the conveyor can accurately convey and place stents to the preset position, and can return the stents safely, the mechanical operation of the whole process is achieved, and the high practical value is achieved.

Description

technical field [0001] The invention relates to the technical field of devices for providing openings or preventing collapse of tubular structures of the human body, and in particular to a 3D printed vascular stent delivery device. Background technique [0002] The stent intervention method has the advantages of less trauma, fewer complications, and better results, and is the main method for treating vascular stenosis. Stent intervention usually requires the use of a delivery mechanism to implant a vascular stent into the body. [0003] The existing delivery mechanism generally includes a catheter assembly and a handle part connected to each other. The catheter assembly usually includes an outer tube and an inner tube. The vascular stent can be arranged between the inner tube and the outer tube. The guide wire passes through; the handle part includes a housing suitable for holding and a driving assembly for driving the inner tube to reciprocate, the outer sleeve is fixed to...
