Soft silicone rubber or polyurethane is often used as a preparation material. The drainage tube is usually placed through a local incision channel after clinical operation, and the drainage tube needs to be sufficiently and firmly fixed after placement. At present, the most common drainage tube fixing mode is that the drainage tube is fixed by locally hanging skin and subcutaneous tissues through silk threads, the operation is convenient, but the silk threads are easy to break and are not firm in fixation, and the drainage tube is easy to fall off or shift, so that the drainage effect is influenced. Meanwhile, long-time continuous local silk thread traction may cause poor healing of a drainage tube opening, cause infection, local exudation and the like, frequent dressing change or even secondary suture fixation is needed, and pain of a patient is increased.
