Embodiment 1

[0039]    figure 1 Shown is the invention's 1 In the embodiment of the guide wire, the metal wire material of the metal core wire 1 is made of nickel-titanium alloy. The metal core wire 1 has a base section 4 with a diameter of 0.78mm (300cm in the present embodiment); a middle section 5 with a diameter of 0.65mm extending continuously to the front end (30cm in the present embodiment); The conical section 6 (15cm in the present embodiment) that the front end shrinks continuously. The middle section is colored with yellow and black pigments containing barium sulfate polyurethane resin tubes (the length of each tube is 8mm), which is continuously and alternately covered to form a 20cm-long straight line composed of the first and second direct-viewing sign color rings 9 and 10. View logo section 2. Look directly at the base section 4 ends of the sign portion 2, use 2 polyurethane resin tubes colored by red pigments, sandwich the above-mentioned yellow and black signs, and set...

Embodiment 2

[0041] From the base section 4 of diameter 0.78mm (being 300cm in the present embodiment), make the conical section 6 (being 45cm in the present embodiment) of continuous dwindling to the front end of diameter 0.15mm, with the sulfuric acid containing yellow and black pigment coloring The polyurethane resin tube of barium (each tube length is 8mm), is successively and alternately set on the above-mentioned guide wire, forms the direct-view mark part 2 that is made up of the first and second direct-view mark color rings 9, 10 of 25cm long. At the 4 ends of the base section of the direct-viewing sign part 2, two polyurethane resin tubes colored with red pigments are used to clamp the above-mentioned yellow and black signs, and the interval is 10cm, so that the first, second and third direct-viewing sign color circles The direct vision marking part 2 composed of 9, 10, and 11 can more accurately prompt the position where the guide wire is inserted. A platinum coil is installed in...

Abstract

The invention relates to an endoscope guide wire, which solves the problem that the conventional guide wire is easy to break, the problem that the pushing capacity is poor, the problem that the position into which the guide wire is inserted is difficult to judge and the like. The endoscope guide wire comprises a metal core wire and a visual identification mark covered on the surface of the metal core wire. The technical key points of the endoscope guide wire include: the metal core wire is made of an integrative elastic metal wire without a junction surface; the visual identification mark is arranged between the end part of a base section and the front end of a conical section of the metal core wire, and comprises a direct viewing mark part and an X-ray developing part; the direct viewing mark part is formed by a first direct viewing mark color ring, a second direct viewing mark color ring and a third direct viewing mark color ring which are connected alternately and have different colors; the X-ray developing part is formed by X-ray developing metal or an X-ray developing agent-containing envelope; and an ultrathin hydrophilic coating is covered on the surface of the visual identification mark. The endoscope guide wire has a reasonable structure; and on the basis of ensuring the direct vision and X-ray visuality which are required by the endoscope guide wire, the pushing capacity, sliding performance and the like of the guide wire inserted into an endoscope channel are improved comprehensively, and the operability and safety of the endoscope guide wire are improved obviously.

Description

technical field [0001] The invention relates to a guide wire, in particular to an endoscope guide wire mainly used for inserting into a living body through an endoscope for diagnosis and treatment. Background technique [0002] When an endoscope is used to inspect a lumen or the like in a living body or perform medical treatment, it is necessary to insert a guide wire into the endoscope through an opening and a channel of the endoscope. During inspection or treatment, after the endoscope reaches the target site in the body, this guide wire plays the role of guiding the catheter and other interventional devices to the target site. [0003] Therefore, the quality of the guide wire determines the success rate of the operation, the operation time and the incidence of complications. At present, the commonly used endoscopic guide wires are not easy to operate, that is, the support hardness and rotation compliance are poor, and it is impossible to efficiently select the entrance o...
