Matched guide wire and guide tube

A technology that cooperates with each other and guides the wire. It is used in catheters, medical science, surgery, etc. It can solve the problems of difficulty in judging the relative position of the guide wire and the catheter, the catheter guide wire cannot be reached, and the X-ray irradiation time is long. Effectiveness of radiation exposure time, simplified operation, patient and doctor protection

Problems solved by technology

[0002] Both the catheter and the guide wire in the prior art are monochrome, and it is difficult to judge the relative relationship between the guide wire and the catheter when the catheter is delivered along the guide wire into the human body lumen or the guide wire is delivered along the catheter into the human body lumen during clinical operations. location, it needs to be carried out under X-ray monitoring, and patients and doctors are exposed to X-rays for a long time
Under the condition of ensuring safety, reducing the time of X-ray exposure of patients and doctors during interventional therapy has always been one of the directions of efforts of interventional consumables manufacturers. Need to propose new technical solutions

Embodiment 1

[0027] Embodiment 1: the manufacture of guide wire of the present invention

[0028] With superelastic medical metal material wire as the core, such as nickel-titanium shape memory alloy wire, or variable-diameter nickel-titanium shape memory alloy wire, or nickel-titanium close-packed helical spring wire, or medical stainless steel wire, or medical stainless steel close-packed coil spring Wire as the core, or other non-metallic superelastic material wire as the core of the guide wire, using a surface spraying process, or a vacuum evaporation process, or a surface dipping process to coat a layer of hydrophilic material on the core material of the guide wire , and then segmentally dye the hydrophilic material coating, or spray colored hydrophilic material, or use laser processing to make the surface hydrophilic material have different color segments, and then the guide wire of the present invention is obtained. Refer to Figures 1 to 5.

Embodiment 2

[0029] Embodiment 2: the manufacture of catheter of the present invention

[0030] The catheter is made of medical polymer materials, manufactured by extrusion process, and then the hydrophilic coating of the catheter is dyed or sprayed with colored hydrophilic materials, or the surface hydrophilic material has different color segments by laser treatment. That is, the catheter of the present invention was obtained. Refer to FIG. 6 to FIG. 10 .

Embodiment 3

[0031] Embodiment 3: Cooperative use of the 2-color-segment guide wire and the catheter of the present invention

[0032] With the head end of the guide wire of the present invention as a starting point, every interval of 100mm is dyed yellow and red successively to form yellow and red alternate color segments, and the length of the color segments is 100mm, thus obtaining the guide wire of the present invention (also It can be referred to as the color separation guide wire for short). Refer to Figure 1.

[0033] With the head end of the catheter of the present invention as a starting point, every 100mm is dyed yellow and red successively to form yellow and red alternate color segments, and the length of the color segments is 100mm, thus obtaining the catheter of the present invention (also can be called for short) for color-segment conduits). Refer to Figure 6.

[0034] In clinical use, first deliver the guide wire 1 into the human body through the sheath 9, and record how ...

Abstract

The matched guide wire and guide tube have corresponding color sections in their surfaces, and by means of the color sections, the relative position between the guide wire and the guide tube may be determined easily. The present invention can reduce the X-ray radiation time during introducing the guide wire into the guide tube to protect both patient and doctor while simplifying and easing the operation of the doctor.

Description

technical field [0001] The invention relates to a minimally invasive surgical consumable, in particular to a guide wire and a catheter for interventional treatment. Background technique [0002] Both the catheter and the guide wire in the prior art are monochrome, and it is difficult to judge the relative relationship between the guide wire and the catheter when the catheter is delivered along the guide wire into the human body lumen or the guide wire is delivered along the catheter into the human body lumen during clinical operations. The location needs to be carried out under X-ray monitoring, and patients and doctors are exposed to X-rays for a long time. Under the condition of ensuring safety, reducing the time of X-ray exposure of patients and doctors during interventional therapy has always been one of the directions of efforts of interventional consumables manufacturers. New technical solutions need to be proposed. Contents of the invention [0003] The purpose of...
