Abstract

The invention relates to the technical field of medical instruments, and particularly discloses a stent film covering device and a stent film covering method.The stent film covering device comprises an extrusion module used for controlling release of a film covering solution, a displacement module used for controlling the extrusion module to move back and forth in the fixed direction and a rotating module used for fixing a bare stent and enabling the bare stent to rotate according to the set rotating speed; the extrusion module is arranged on the displacement module, the displacement module and the rotating module are arranged on a fixing plate, and a solution outlet of the extrusion module faces the direction of the bare stent fixed to the rotating module. The rotating module is used for driving the extruding module to rotate, so that the film coating solution released by the extruding module is uniformly arranged on the surface of the bare stent driven by the rotating module to rotate. The invention further discloses a stent film coating method. The technical problems that a self-made film is large in operation difficulty and long in manufacturing time, and the size of the self-made film is not accurate are solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a stent covering device and a stent covering method. Background technique [0002] Usually, tumors, thrombus or similar diseases often lead to narrowing or even blockage of human lumen or blood vessels, and the current trend is to use stents for treatment. Covered stent grafts have been widely recognized in the field of implanted medical devices in recent years, and their advantages include excellent biocompatibility and ultra-slip properties. The mechanism is to use a special delivery system to send the stent graft into the lesion and then open it to open the blood vessel blocked by thrombus, the tumor body and the blood isolation, or the narrow part of the cavity. This technique greatly reduces surgical mortality and postoperative complications, reduces surgical trauma, and patients recover faster. [0003] At present, the existing mature stent-graft manufacturing met...
