Embodiment 1
[0020] Embodiment 1: A guide wire for catheter percutaneous puncture, including a guide wire head end 2 and a guide wire tail end 3, the guide wire head end 2 is connected to the guide wire tail end 3 through a guide wire assembly 1, and the guide wire The protective assembly 4 is installed on the outer surface of the head end 2 and the outer surface of the guide wire tail end 3. The guide wire assembly 1 includes a spring coil 11, a safety wire 12 and a core wire 13. The left end of the spring coil 11 is connected to the right side of the guide wire head end 2. , and the right end of the spring coil 11 is connected to the left side of the guide wire tail end 3, the safety wire 12 is set on the inner surface of the spring coil 11, and the core wire 13 is installed in the middle of the safety wire 12, specifically, the main color device is connected to the guide wire Rinse the device with sterile heparinized saline after the Luer shaft of the wire distributor is inserted, insert...
Embodiment 2
[0021] Example 2: See Figure 4 , the guide wire tip 2 is an A-curved structure, specifically, connect the main color device to the Luer shaft of the guide wire distributor, rinse the device with sterile heparinized saline, and insert the guide wire tip 2 into the Inside the puncture needle, let the guide wire tip 2 pass through the puncture needle, fix the position of the guide wire tip 3, hold the guide wire tail 3 to keep the position still, withdraw the puncture needle, push the catheter along the guide wire tip 2, and then The guide wire head end 2 is passed through the patient's bladder percutaneously through the catheter, which is suitable for use in bladder percutaneous puncture.
Embodiment 3
[0022] Example 3: See Figure 5 , the guide wire tip 2 is a J-bent structure, specifically, connect the main color device to the Luer shaft of the guide wire distributor, rinse the device with sterile heparinized saline, and insert the guide wire tip 2 into the Inside the puncture needle, let the guide wire tip 2 pass through the puncture needle, fix the position of the guide wire tip 3, hold the guide wire tail 3 to keep the position still, withdraw the puncture needle, push the catheter along the guide wire tip 2, and then The guide wire head end 2 is passed through the patient's vein percutaneously through the catheter, which is suitable for use in venous percutaneous puncture.
