Anal and rectal dilation catheter device

Abstract

The invention innovatively adopts a flexible airbag anal and rectal dilator. The risk of damage to the intestinal canal during the anal and rectal dilation process is reduced, and serious complications are avoided. Because the current hard anal dilator strongly passes through the anastomotic stenosis position, causing pain and extreme discomfort; a patient is extremely uncooperative, crying and uneasy, and affecting the dilation effect; the flexible airbag anal and rectal dilator is smooth and comfortable and greatly reduces the pain and the discomfort of the patient, the patient is highly cooperative, and the anal dilation effect is good. If the hard anal dilator is adopted, the strong dilation has the risk of anastomotic rupture when the wound is not healed in the early postoperative period, the dilation can be performed generally 2-3 weeks after the surgery, the anastomotic local scar is formed at the moment, and the dilation is difficult. The flexible airbag anal and rectal dilatoris soft, the dilation strength can be controlled and adjusted, the dilation can be performed in the early postoperative period to avoid scar formation, and the dilation effect is better.

Description

technical field [0001] The invention relates to a device for expanding the anus and rectum, in particular to a device for expanding the anus and rectum by injecting liquid into the anus and rectum after operation of congenital anal atresia and congenital Hirschsprung, so as to relieve pain of the patient, support the wound, consolidate the effect of the operation, and prevent the formation of scars And cause the anus of wound surface, rectum expansion device. Background technique [0002] The invention overcomes the deficiency of the background technology and provides a device for expanding the anus and rectum. The anus and rectum expansion device has the function of continuous expansion, and the expansion degree can be adjusted. Reasonable use can consolidate the operation effect, reduce complications and pain, increase the patient's treatment cooperation, and have advantages in terms of convenient operation.

AI Technical Summary

Problems solved by technology

[0003] Congenital anal atresia and congenital Hirschsprung surgery require daily anal dilation treatment to prevent anastomotic stenosis. During the recovery period after discharge from the hospital, the anal dilation is performed by the parents; the anal dilators currently used are all hard anal dilators. The material is metal or plexiglass. Although they have been trained, because the parents are not familiar with the anatomical characteristics of the rectum, bleeding may occur during the anal expansion process, and even colon perforation, abdominal distension, fever, peritonitis and other symptoms may occur. If the treatment is not timely, life-threatening
