Description

Technical Field

[0001] The utility model relates to the technical field of medical catheter guidewires, in particular to a coating coating device for medical catheter guidewires. Background Art

[0002] Interventional therapy is a minimally invasive treatment using modern high-tech means. Under the guidance of medical imaging equipment, special catheters, guidewires and other precision instruments are introduced into the human body to diagnose and locally treat pathological conditions in the body. Interventional therapy uses digital technology to expand the doctor's field of vision. With the help of catheters and guidewires, the doctor's hands are extended. Its incision (puncture point) is only the size of a grain of rice. Without cutting human tissue, many diseases that could not be treated in the past and must be treated surgically or with poor medical treatment effects can be treated, such as tumors, hemangiomas, various bleeding, etc. Interventional therapy has the characteristics of no surgery, less trauma, fast recovery, and good results. It is the development trend of future medicine. At present, in order to reduce the pain of patients, it is usually necessary to apply a lubricating layer on the guidewire to reduce friction when the guidewire in the relevant technology is used.

[0003] However, most of the existing medical catheter guidewire coating devices are not convenient for applying lubricant to multiple guidewires at the same time, which brings great inconvenience to users. At the same time, the coating cotton will deviate from the guidewire surface during the coating process, reducing its coating effect. Therefore, those skilled in the art provide a medical catheter guidewire coating device to solve the problems raised in the above background technology. Utility Model Content
