The abdominal drainage tubes are mostly made of rubber. Rubber itself has the characteristic of becoming easily fatigued and breaking. Many doctors later switched to using silicone tubes because of this, as there have been many similar incidents with rubber tubes. However, silicone tubes are not as cheap as rubber tubes, nor are they as soft and elastic. Veteran doctors who are accustomed to rubber tubes are not too fond of silicone tubes, and besides, softer and more elastic tubes feel better in hand. All in all, which tube to use depends on the doctor's personal habit. But no matter which tube is being removed, it doesn't make a difference to the doctor; it's definitely a technical task.
Medical students who have undergone surgical internships have removed tubes before; teachers generally let students practice this task. Having rotated through gynecology, Pan Shihua has removed drainage tubes several times and has a feel for this, which is why he dares to use some force.
