Embodiment 1

[0029] Such as figure 1 A titanium alloy guide wire for surgical interventional treatment is shown, comprising a titanium alloy thin-diameter thin-walled tubing 1 and a noble metal tip 2 arranged at the distal end of the titanium alloy thin-diameter thin-walled tubing 1, the titanium alloy thin-diameter thin-walled The tube material 1 is divided into three parts from far to near: the distal section of the guide wire, the middle section of the guide wire and the proximal section of the guide wire. The tube wall of the far section of the guide wire has a single helical groove one 3, and the tube wall of the middle section of the guide wire has a single helical groove two 4, and the single helical groove one 3 is an equal-pitch helical groove. The single helical groove two 4 is a variable pitch helical groove, the groove widths of the single helical groove one 3 and the single helical groove two 4 are all the same, the pitch of the single helical groove two 4 gradually increases ...

Embodiment 2

[0038] In this embodiment, the difference from Embodiment 1 is that the material of the noble metal tip 2 is gold, the material of the titanium alloy thin-diameter thin-walled pipe 1 is Ti6Al4V titanium alloy, and the titanium alloy thin-diameter thin-walled pipe 1 is made of gold. 1 has an outer diameter of Φ0.5 mm and a wall thickness of 0.1 mm, the groove widths of the single helical groove 1 and the single helical groove 2 4 are both 0.2 mm, and the pitch of the single helical groove 3 is 0.5 mm. The pitch of the single helical groove 2 4 is a gradual pitch and it increases by 0.3 mm from far to near, the length L1 of the distal section of the guide wire is 10 mm, the length L2 of the middle section of the guide wire is 90 mm, and the length of the guide wire near The length of the segment L3=200mm.

[0039] In this embodiment, the structures of other parts are the same as those in Embodiment 1.

Embodiment 3

[0042] In this embodiment, the difference from Embodiment 1 is that the material of the noble metal tip 2 is platinum-iridium alloy, the material of the titanium alloy thin-diameter thin-walled pipe 1 is Ti6Al7Nb titanium alloy, and the thin-diameter thin-walled titanium alloy pipe 1 is Ti6Al7Nb titanium alloy. The outer diameter of the wall pipe material 1 is Φ2mm and its wall thickness is 0.2mm, the groove width of the single helical groove one 3 and the single helical groove two 4 is 0.1mm, and the pitch of the single helical groove one 3 is 0.2mm, The pitch of the single helical groove 2 4 is a gradual pitch and it increases by 0.1 mm from far to near, the length L1 of the distal section of the guide wire is 20 mm, the length L2 of the middle section of the guide wire is 100 mm, and the length of the guide wire near The length of the segment L3=200mm.

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...
