Problems solved by technology

[0004] The use requirements of the guide wire are proximal support and distal flexibility. However, the current products on the market can maintain the proximal support, but the distal end is not soft enough; the distal end can maintain softness, but the proximal support is not enough. The stainless steel material can To ensure the support performance, the nickel-titaniu

Abstract

The invention relates to the technical field of medical instruments, and discloses a medical micro guide wire. The medical micro guide wire comprises a flexible core wire and a supporting outer wall; the flexible core wire comprises a supporting section and a flexible section; the flexible section is located on the side close to the far end of the flexible core wire; the supporting section is located on the side close to the near end of the flexible core wire; the flexible section can be flexibly arranged in a blood vessel in a penetrating mode; the supporting section of the flexible core wire is coated with the supporting outer wall; the supporting outer wall is used for providing supporting strength for the supporting section; and the flexible core wire and the supporting outer wall are coaxial and integrally formed. The medical micro guide wire achieves the supporting performance at the near end, achieves the flexible performance at the far end; moreover, the flexible core wire and the supporting outer wall are coaxial and integrally formed, and no connecting part is arranged between the flexible core wire and the supporting outer wall, and thus, the problem of breakage is avoided, and the safety of the medical micro guide wire is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical micro guide wire. Background technique [0002] Stroke, commonly known as stroke, includes ischemic stroke (also known as cerebral infarction) and hemorrhagic stroke (including parenchymal hemorrhage, ventricular hemorrhage and subarachnoid hemorrhage), which is a disease of brain cell and tissue necrosis . Among them, ischemic stroke is an important cause of global adult disability and death. With the improvement of living standards, the life expectancy of my country's population has increased significantly, and the degree of aging has aggravated. At the same time, the number of obese and diabetic people has increased. The incidence rate is getting higher and higher, and it has become one of the main diseases that endanger the lives of Chinese people. The increase in patients with cerebrovascular diseases has promoted the development of neurointerventional sur...
