Abstract

The invention relates to the technical field of medical instruments. The invention discloses a medical micro guide wire for interventional therapy and a manufacturing method thereof. The micro guide wire comprises an inner core, the inner core comprises a conveying section, a gradually-changing diameter section and a head end smooth section which are integrally formed and sequentially arranged. Adeveloping gold wire is tightly wound on the head end smooth section, the inner core and the outer layer of the developing gold wire are wrapped by a TPU layer, the surface of the TPU layer is coatedwith a hydrophilic coating, and the micro guide wire is manufactured through the following steps of material preparation, gold wire winding, gold wire fixing, sheath wrapping and coating of hydrophilic coating. The surface of the micro guide wire is smooth, the head end is soft, the developing gold wire is tightly wound on the smooth section of the head end, and light and shadow display is more concentrated, so that the light and shadow intensity in a certain area is enhanced, and the developing effect is greatly improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical micro guide wire for interventional therapy and a manufacturing method thereof. Background technique [0002] During the clinical operation of cardio-cerebral surgery, due to the intricate blood vessels in the lesion, it is often necessary to use a small-diameter precision nerve micro-guide wire to guide the surgical instruments to the lesion, so that medical staff can adopt a more effective treatment plan. The farther the microguide wire can enter the blood vessel, the higher the support force it can provide, and the better the possibility and effectiveness of the treatment. However, since the diameter of the micro guide wire is very small, often 0.014” or even smaller, the development position of the front end needs to be clear to ensure that the operator can accurately locate it. Therefore, the micro guide wire with clear front development, soft tip and good ...
