A vascular stent conveying system includes a housing, an outer cannula, a cleaning tube, an inner cannula, and a driving assembly. The outer cannula is located outside the housing and is connected to a first end of the housing. The cleaning tube is connected to a second end of the housing, a first end of the cleaning tube is located in the housing, and a second end of the cleaning tube extends out of the housing. A part of the inner cannula is located in the housing, a first end of the inner cannula extends into the outer cannula, and a second end of the inner cannula extends from the first end of the cleaning tube to a tube chamber of the cleaning tube. A part of the driving assembly is located in the housing, and operably engaged with a part of the inner cannula located in the housing.

Vascular stent delivery system and tubing assembly thereof

A highly retractable intravascular stent delivery system, including a tube assembly and a rotation driving assembly. The tube assembly includes an outer tube, an intermediate tube, and inner tube, wherein an intravascular stentand a stent retaining blockare provided within the outer tube. The rotation driving assembly includes a housing, an outer screw, and an intermediate screwlocated within the housing, as well as a driving member. The driving member allows two screws to rotate at opposite directions, so as to drive the outer tubeto move toward the proximal end, and the intermediate tubepushes the stent retaining blockand the intravascular stentto move toward the distal end. The system uses three-lay tube structure and uses driving gear to drive two screws to move at directions opposite to each other, such that the intermediate tubeand the outer tubeare driven to move to directions opposite to each other. Therefore, the axial retraction of the intravascular stents can be effectively offset and axial movement of the intravascular stents due to axial retraction of the intravascular stents is avoided, thereby accurately implanting the stents into the body.
