[ background Art ]

Colorectal cancer (colorectal cancer, CRC) is third among the worldwide incidences. Among the numerous treatments for CRC, surgery is an important means of radical treatment. Wherein the number of rectal cancers is relatively large due to the complexity of rectal dissection and the specificity of physiological functions. In recent years, with the continuous development of surgical technology and the cooperation of new auxiliary treatment, more choices are provided for the anorectal protection treatment of medium-low-level rectal cancers, and the anorectal protection rate of the rectal cancer operation is also improved, wherein the Dixon operation can reserve the original anus while radically curing the rectal cancers, and is beneficial to improving the postoperative life quality of patients and is widely applied. The postoperative anastomotic fistula of the rectal cancer is one of the most common complications after various rectal cancers, and is also the most dangerous complication, and causes of the anastomotic fistula include advanced age, malnutrition, anemia, long-term application of hormone medicines, diabetes and the like, and also include poor anastomosis technology, intestinal canal blood circulation disorder, local excessive tension, infection, distal end obstruction of an anastomotic stoma and the like. The indwelling anal canal in the rectal cancer operation has obvious significance for reducing the intestinal cavity pressure, preventing postoperative anastomotic fistula and promoting the recovery of intestinal and anal functions of patients.

The traditional indwelling anal canal fixing method at present comprises the following steps: after the anal canal is placed into the anus, the anal canal is directly fixed to the perianal skin of a patient through a suture, and the fixing method has the following problems: on one hand, perianal pain of a patient after operation is increased, the recovery of gastrointestinal and anal functions of the patient is affected, on the other hand, the risk of local infection is increased, in addition, perianal nerves are abundant and pain sense is sensitive, and when the skin at the perianal nerves is sutured to stimulate nerve ending receptors, the patient can generate severe pain, so that the pain degree of the patient is increased.

Accordingly, there is an urgent need for an anal canal fixator that can effectively fix the anal canal and reduce pain for the patient.
