Background

The clinical surgical drainage tubes have various types, some are used for catheterization, and some are used for wounds, thoracic cavities, brain cavities, gastrointestinal tracts, biliary tracts and the like. Surgical drainage is used for guiding pus, blood and liquid accumulated in human tissues or body cavities to the outside of a body so as to prevent postoperative infection and influence on wound healing. The drainage tubes commonly used at present have problems: firstly, easily deviate from, secondly need puncture needle puncture to the drainage position in advance, go on the second step again and introduce the drainage tube, increase the operating procedure, reduced the success rate.

With the development of minimally invasive technology, the treatment effect on pathological hydrops of various organs or body cavities, such as cyst, abscess, pancreatic pseudocyst, chest, ascites and the like, is good by adopting CT or B ultrasonic guided puncture drainage, hardening, flushing treatment and the like, thereby avoiding the pain of patients caused by surgical operation. Puncture is carried out under CT or supersound guide at present, can adopt pull-wire formula pigtail type drainage tube device (COOK group) drainage, and the device includes pipe, pipe seat and fixed acting as go-between, and the device has the defect to be: on one hand, if the drainage cavity is narrow, a loop is difficult to form; on the other hand, after long-time drainage, the stay wire is adhered to the tube wall, and when the drainage tube needs to be taken out, the loop is difficult to be released, so that the drainage tube cannot be taken out smoothly; in addition, partial patients are not well nursed, and the pull wire is easy to cut and damage when the drainage tube is pulled by the patient.
