[0002] Anorectal surgery is a clinical discipline that treats tumors, trauma and other diseases that occur in the anus and large intestine with surgery as the main method. Anorectal diseases are most common in the anorectal segment. Patients in the anorectal department need to use applicators frequently after surgery. At the same time, the part of the drug delivery device that is in contact with the patient needs to be cleaned and replaced frequently. The general method is to add the liquid medicine to the water and then manually clean it, which is very troublesome, and the precipitation of the liquid medicine during use will affect the therapeutic effect. The cartridge is shaken intermittently to allow the drug to mix evenly, which is very inconvenient
