Embodiment Construction

[0033] In this specification, the same reference numerals are used to denote the same components.

[0034] figure 1 is a schematic longitudinal section of a guide wire according to an embodiment of the present invention. refer to figure 1 , the guide wire mainly includes a core wire 1 , a wrapping wire 2 and a sheath 3 . Each of these three parts is described in detail below.

[0035] The core wire 1 is located in the inner layer of the guide wire, and its cross section is circular or any other suitable shape. The distal end of the core wire 1 is treated with diameter reduction, preferably tapering, so that the distal end of the guide wire can have better flexibility, reduce the hardness of the distal end and improve the pushing performance of the guide wire. The core wire 1 can be made of nickel-titanium alloy, stainless steel, Ti-Nb alloy, Ti-Ni-X alloy, Cu-Zn alloy, Cu-Zn-Ni alloy, Fe-Ni alloy or Fe-Mn alloy with good shape memory Made of high-strength materials, so as...

Abstract

The invention discloses a super-smooth guide wire for use in transradial coronary intervention. The guide wire comprises a core wire, a winding wire and a jacket, wherein the core wire is positioned on the inner layer of the guide wire; the winding wire is positioned on the middle layer of the guide wire and covers the entire core wire; the near end of the core wire is connected with the near end of the winding wire; the far end of the core wire is in a free state; the jacket is positioned on the outer layer of the guide wire and covers most of the winding wire. Compared with the prior art, the super-smooth guide wire has the advantages that the problems of poor supporting property, poor touch feel feedback, easiness in causing vascular injury and incapability of conveniently and repeatedly entering a catheter and the like of the super-smooth guide wire during transradial coronary intervention diagnosis and treatment are solved, and the comprehensive performance of a radiography guide wire is improved comprehensively.

Description

technical field [0001] The present invention relates to the field of disposable medical devices, in particular, relates to a device for diagnosis and treatment of coronary artery intervention, especially for the guidance and positioning of diagnostic and treatment catheters in the human body during transradial artery access. Super smooth guide wire. Background technique [0002] Percutaneous coronary intervention refers to the diagnostic and therapeutic method of diagnosing the degree of coronary artery stenosis through the catheter and performing corresponding treatment. At present, the interventional pathways for coronary interventional diagnosis and treatment are mainly divided into femoral artery and radial artery. In 1989, Canadian doctor Campeau pioneered percutaneous radial artery puncture for coronary angiography. In 1992, Dutch doctor Kiemenij reported the results of treatment using this approach. With the promotion and popularization of coronary artery interventi...
