Description

technical field [0001] The invention relates to the technical field of clinical medical equipment, in particular to a replaceable drug delivery device for clinical use in anorectal surgery. Background technique [0002] Anorectal diseases refer to diseases that occur in the anus and large intestine, and most of them occur in the anus and rectum. Many anorectal diseases are not serious or serious diseases. But its troublesome and painful degree ranks ahead of all kinds of diseases.

Problems solved by technology

[0003] In the current anorectal surgery, when feeding the intestinal tract, most of them clean the anorectal position through the applicator, and then replace the drug delivery head to administer the anorectal position, so as to prevent the given medicine and the bacteria on the intestinal wall from penetrating into the intestine. rectum, so as to prevent the problem that the drug ingredients are not easily absorbed and affect the curative effect, and also avoid the problem that bacteria follow the liquid into the intestinal tract and cause deep intestinal infection, but this method needs to be replaced every time the drug is administered. The cleaning head and drug delivery head of the drug device need to insert the drug device into the anorectum of the patient multiple times. For the medical staff, the operation steps are increased, which is inconvenient to use. For the patient, the patient feels discomfort many times. Therefore, a replaceable drug delivery device is needed, that is, a drug delivery device that can be inserted into the anorectum once to complete cleaning and drug delivery
