Guide wire for peripheral vascular interventional therapy

Abstract

The invention discloses a guide wire for peripheral vascular interventional therapy. The guide wire comprises a handheld end and a polytetrafluoroethylene coating, one side of the handheld end is fixedly connected with a head end, a core wire is arranged in the handheld end, and one side of the outer portion of the handheld end is coated with the polytetrafluoroethylene coating. According to the guide wire for peripheral vascular interventional therapy, a tungsten-containing developing layer is arranged, the head end, a gradually-changing diameter section and the outside of a straight section are tightly coated with the tungsten-containing developing layer, and the head end and one side of the exterior of the core wire are provided with the tungsten-containing developing layer, so that the light and shadow intensity in a certain area can be enhanced, a developing effect can be greatly improved by enhancing the light and shadow intensity in an enhancement area, the diameter of the straight section of the head end can be reduced to 0.08-0.12 millimeters through the gradually-changing diameter section of the core wire, the head end of the guide wire can be softer by reducing the diameter of the straight section to 0.08-0.12 millimeters, the ability of the guide wire to pass narrow and closed sections can be enhanced through a softer guide wire, and the light and shadow intensity in the enhancement area is achieved, and the developing effect is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a guide wire for peripheral blood vessel interventional treatment. Background technique [0002] In the process of clinical interventional surgery for peripheral vascular disease, due to the stenosis and occlusion of the lesion, it is often necessary to use a guide wire or PTCA guide wire with a smaller diameter to guide diagnostic and therapeutic surgical instruments to the lesion, so that medical staff can take A more effective treatment operation plan, the guide wire or PTCA can reach the stenosis and occlusion of the peripheral blood vessel under the image of the digital subtraction machine (DSA). In addition, the light and shadow intensity in the treatment guide wire area is weak, and the developing effect is poor. In addition, the lubricity and corrosion resistance of the hand-held end of the traditional peripheral vascular interventional treatment guide wire are po...
