Description

Novel surgical postoperative drainage tube capable of being dredged

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a novel drainage tube capable of dredging after surgery.

Background

Under the physiological state, the intra-abdominal pressure is equal to or slightly higher than the atmospheric pressure, so the traditional non-negative pressure drainage tube has better drainage effect as a drainage object after the abdominal cavity operation. However, in the case of a surgical operation with a large amount of subcutaneous fat, such as a breast operation or a inguinal lymph node cleansing operation, since the pressure of the gap between the skin and the superficial fascia is small, a surgical drainage tube with a negative pressure device is a commonly used postoperative drainage.

On the premise of good air tightness, due to the existence of negative pressure in the drainage tube, compared with a common drainage tube without negative pressure, the drainage tube has better drainage effect, reduces the residual of effusion in an operation area, and reduces the incidence rate of perioperative infection events. At present, most negative pressure drainage tubes are provided with longer side holes at the tail end of the inner side of a tube cavity to achieve the purpose of preventing blockage, but in clinical practical application, floccules formed by solidification of liquefied fat, inflammatory exudation and the like can still be deposited in a tube cavity after the drainage tubes are placed for several days, so that the drainage tubes are blocked, and even the drainage tubes need to be pulled out and placed again when necessary, so that the infection risk and burden of patients are increased. Part of the medical centers adopt a split negative pressure drainage ball and a drainage tube, the drainage tube is cut from the tail end of the outer side of the tube cavity, and the tube cavity floccule is taken out mechanically to remove blockage. The method is limited by the fragile nature of the floe, and often results in incomplete removal due to floe breakage, or postoperative infection due to retrograde entry of pathogens into the patient via the lumen.

Therefore, how to provide a novel drainage tube capable of dredging after surgical operation is a problem which needs to be solved by the technical personnel in the field.
