Summary:The utility model discloses a special tunnel needle for an implantable tube in peritoneal dialysis operations. The back end of the existing tunnel needle (1) is provided with a connecting cylinder body (2) connected with a dialysis implantable tube. A skidproof groove (3) is arranged on the connecting cylinder body (2), and the diameter of the skidproof groove is small than the diameter of the back end part of the tunnel needle (1), and is larger than the inner diameter of the dialysis implantable tube. The utility model has the advantages of reasonable structural design, and convenient use and operation. The utility model solves the problem that the existing tunnel needle is easy to slide (or is difficult to pull out) after the existing tunnel needle is sheathed with a dialysis tube in clinical application.
