MICRO-MEDICAL ROBOT-BASED GUIDEWIRE FOR VASCULAR INTERVENTION

Abstract

Disclosed is a micro-medical robot-based guidewire for vascular intervention, the guidewire being characterized by comprising: a core shaft; an outer coil wound around the outer circumference of a distal portion of the core shaft; a front end tip to which at least a portion of the front end of the distal portion of the core shaft and the front end of the outer coil are joined; an outer joint part that joins the rear end of the outer coil to the rear end of the distal portion of the core shaft; an inner joint part that is located inside the outer coil and formed so as to join the outer coil and the outer side of the core shaft between the front end tip and the outer joint part; and at least two magnetic bodies which have cavities formed therein and are located inside the outer coil in at least some sections between the front end tip and the inner joint part, wherein at least a portion of the front end of the core shaft positioned between the front end tip and the inner joint part passes through the cavities.
