The crushed piece 14 is divided into two groups and is symmetrically installed on the upper end of the upright pole 13. The crushed piece 2 15 is divided into two groups and is symmetrically installed in the external extraction cover 4. The crushed piece 2 15 is used in conjunction with the crushed piece 14. The sealing plug 6 is inserted into the bottom of the rotating ring 11. When a section of the drainage tube body is blocked, the medical staff can insert the syringe into the obstruction external extraction device at the corresponding position, and introduce the obstruction into the obstruction external extraction device by negative pressure suction. When the obstruction enters the external extraction device, the obstruction can be refined and externally extracted through the internal crushing component, which greatly improves the processing efficiency of the abdominal drainage tube blockage. In addition, the multi-stage distribution of the obstruction external extraction device can quickly extract the obstruction at the corresponding position, shorten the distance for guiding the obstruction, and improve the processing efficiency.
