The invention belongs to the technical field of medical apparatuses, and discloses a novel peritoneal dialysis catheter drifting reset device which comprises a reset tube. The two sides of the reset tube are each provided with a plurality of through holes. The through holes are vertically arrayed and distributed at equal intervals. The reset tube sleeves an inner core. The two sides of the inner core are each connected with a plurality of cylindrical buckles through a rotating shaft. A pull ring is welded to the tail end of the inner core. An extension spring is welded between the pull ring and the reset tube and sleeves the inner core. An LED spotlight is embedded in the center of the lower end of the reset tube. By pulling the pull ring, the buckles can be drawn back, and the reset tubecan be inserted in a dialysis tube needing to reset; by releasing the pull ring and drawing back the inner core, the buckles are driven to pop up to the two sides, barbs can lock the dialysis tube, the dialysis tube can be prevented from disengagement, and then the reset device can move; by means of the LED spotlight, illumination can be improved, the reset tube can conveniently penetrate into anopening of the dialysis tube, and therefore the set dialysis tube returns to a proper position, and then no surgery needs to be carried out.
