A titanium alloy guide wire for surgical intervention

Abstract

The invention discloses a titanium alloy guide wire for interventional therapy. The titanium alloy guide wire comprises a titanium alloy small-diameter thin-wall tube and a noble metal end head which is distributed at the far end of the titanium alloy small-diameter thin-wall tube; the titanium alloy small-diameter thin-wall tube is divided into a guide wire far section, a guide wire middle section and a guide wire near section from far to near; a single spiral groove I is formed in the tube wall of the guide wire far section; a single spiral groove II is formed in the tube wall of the guide wire middle section; the single spiral slot I is an uniform-pitch spiral groove; the single spiral groove II is a variable-pitch spiral groove; the groove widths of the single spiral groove I and the single spiral groove II are same; the pitch of the single spiral groove II is gradually increased from far to near, and the pitch at the far end of the single spiral groove II is equal to that of the single spiral groove I; the groove depth of the single spiral groove I and the single spiral groove II is the same as the wall thickness of the titanium alloy small-diameter thin-wall tube. The titanium alloy guide wire disclosed by the invention is simple in structure, reasonable in design, simple and convenient to machine and manufacture, good in using effect, and capable of effectively solving the problems such as a complex machining process, high cost and poor adaptability of the existing titanium alloy guide wire.

Description

technical field [0001] The invention relates to a surgical interventional treatment instrument, in particular to a titanium alloy guide wire for surgical interventional treatment. Background technique [0002] An interventional guide wire, also known as a guide wire or guide wire, is one of the main tools for percutaneous catheterization. The guide wire guides, supports and positions the catheter, helps the catheter enter blood vessels and other cavities, and guides the catheter to reach the lesion smoothly. It is an indispensable accessory product for many interventional devices and is used in a large amount. The annual consumption of guide wires in the world is about 64 million, and its market sales are 700 million US dollars. In recent years, my country's annual consumption of guide wires is 1.5 million, and the market capacity is 270 million yuan, accounting for 5% of the world market share. With the popularization of interventional therapy and intensive care technolog...
