Embodiment 1
[0080] See figure 1 , this embodiment schematically presents a microcatheter system according to an embodiment of the present invention, which includes a guide wire 10, a catheter 20, a flusher 30, a shaping needle 40, a threading needle 50, and a twist control device 60, wherein,
[0081] The guide wire 10 can be penetrated into the lumen of the catheter 20, assisting the catheter 20 to enter and locate the target position in the peripheral and abdominal blood vessels, and then the guide wire 10 is withdrawn from the body, and the catheter 20 remains in the blood vessel as a channel for delivering embolic materials, drugs or contrast agents In the cavity, the luer connector at the proximal end of the catheter 20 is connected to the syringe, and the embolic material, drug or contrast agent is injected into the target blood vessel through the catheter to achieve the function of diagnosis or treatment;
[0082] The irrigator 30, the shaping needle 40, the threading needle 50 and...
Embodiment 2
[0171] The product packaging method of embodiment 2 microcatheter system
[0172] In this embodiment, the microcatheter system products are specifically divided into a catheter guide wire set, a catheter set and a guide wire set, and each set is individually packaged as follows.
[0174] Contains a set of catheter 20, guide wire 10, flusher 30, twist control device 60, threading needle 50, and shaping needle 40. The inner packaging is as follows:
[0175] Catheter 20 and guide wire 10 are respectively placed in the double-lumen coil for fixing, put into the inner packaging bag (large), and sealed; the schematic diagrams of the double-lumen coil and the inner packaging bag (large) are respectively shown in Figure 11 with Figure 12 , The material of the double-cavity coil can be selected from HDPE, PP, PC, etc., and the material of the inner packaging bag (large) can be selected from Tyvek 1073B uncoated and PET12 / SPE-2 50.

Embodiment 3
[0191] Embodiment three, the use method of the microcatheter system of this embodiment
[0192] The microcatheter system is used for infusing diagnosis, embolism or therapeutic substances through the human body's periphery and abdominal blood vessels. This microcatheter system cannot be used in neurovasculature.
[0193] The steps of using the microcatheter system can be summarized as follows:
[0194] After taking the catheter 20, guide wire 10 and accessories out of the inner packaging bag, use the irrigator 30 to perfuse heparinized saline into the double-lumen coil, let the catheter 20 and guide wire 10 be fully soaked, and then take them out of the double-lumen coil ;
[0195] Guide wire 10 and catheter 20 tip shaping (if necessary);
[0196] The catheter 20 and the guide wire 10 are passed through the hemostatic valve to the contrast catheter and pushed to the distal end of the contrast catheter. Carefully push the catheter 20 and the guide wire 10 through the contras...

Abstract
The invention discloses a micro-cathetersystem and a packaging and using method thereof. The micro-cathetersystem comprises a guide wire, a catheter, a flusher, a harness cord needle, a shaping needle and a torsion control device. The guide wire can penetrate into an inner cavity of the catheter and assist the catheter in entering a target position in a blood vessel, then the guide wire is withdrawn out of a body. The catheter serves as a channel for conveying an embolism material, a medicine or a contrast media and is reserved in a blood vessel cavity. A Luer taper at the near end of the catheter is connected with an injector, and the embolism material, the medicine or the contrast media is injected into the target blood vessel through the catheter. The flusher is used for flushing thecatheter, the guide wire and the like. The shaping needle consists of a straight core wire and is used for shaping the head end of the catheter. The harness cord needle is used for assisting the guidewire in entering the catheter or assisting the guide wire in shaping. The torsion control device is used for torsion control of the guide wire. According to the invention, the micro-catheter system has the advantages of low cost and high convenience and operability, can meet the requirements of daily treatment, such as the classic TACE operation, and has an important significance in the fields ofmedical instruments and the like.
Description
technical field [0001] The invention relates to the technical field of interventional medical devices, in particular to a microcatheter system and its packaging and use methods. Background technique [0002] Interventional therapy is an emerging treatment method between surgical treatment and medical treatment. Without exposing the lesion by surgery, a small channel with a diameter of a few millimeters is made on the blood vessel or skin, or through the original pipeline of the human body, in imaging equipment. (For example: angiographymachine, fluoroscopymachine, CT, MR, B-ultrasound, etc.) is a minimally invasive treatment method for local lesions, which has the advantages of small trauma, simplicity, safety, effectiveness, fewer complications and significantly shortened hospitalization. advantage of time. [0003] The annual incidence of liver cancer in China accounts for about 53% of the world's total, and more than 70% of the patients are diagnosed at the advanced st...
