[0029] Specifically, the working process or working principle of the new guidewire device for the urinary tract is as follows: in the specific new guidewire device for the urinary tract, a guidewire is usually used, and the guidewire needs to be placed in the human body during use. However, during the placement process, since the guidewire itself is thin and relatively sharp, it is not only difficult to insert quickly, but also scratches the patient during the placement process. In addition, most guidewires contain chemical substances on the outside, which can easily cause discomfort to the patient, are not skin-friendly, and are not convenient for operators to use. Therefore, the technical solution can solve the above problems. When the operator uses it, first, by setting the catheter 14, the guidewire body 11 can be guided, and then the sealing cover 17 is removed. The sealing cover 17 can protect the guidewire body 11 well to prevent external bacteria, dust and other harmful substances from contaminating the guidewire body 11. The limit pin 13 is removed. By setting the limit pin 13, the guidewire body 11 can be effectively limited, and the guidewire body 11 is spiral.
