Description

Enterostomy expander

Technical Field

The invention relates to the technical field of medical instruments, in particular to an enterostomy expander.

Background

An enterostomy is a surgical operation mode which is used for artificially opening an opening on the abdominal wall, pulling a section of intestinal canal out of the abdominal cavity, and sewing the opening on the abdominal wall for excreting excrement or urine. However, in actual operation, the skin and mucosa around the enterostomy naturally retract, and if the correct operation of dilating the enterostomy cannot be adhered to after the operation, complications of enterostomy stenosis can be caused, so that the enterostomy reformation operation must be performed, which not only causes the pain of the patient after the secondary operation, but also causes psychological trauma to the patient.

Such patients are medically known as "ostomy persons". The physical appearance of the ostomate is changed, the excrement can not be controlled at will, and the trouble is brought to patients in social contact, diet, peculiar smell treatment, pocket making use and the like, so that the ostomate as a special group in the society needs care and social help of family members and needs rehabilitation guidance of medical care personnel.

According to incomplete statistics, more than 10 million patients in China need to perform permanent intestinal fistulization operation every year, the stomal stenosis is one of the most common complications after colorectal cancer operation, and the occurrence rate of the stomal stenosis reported abroad is 2% -10%; the domestic report rate is 6-15%, and the occurrence rate can be found in any period after the operation, the defecation of a patient is not smooth due to the narrow stoma, and the excrement can be blocked in serious cases. The prevention and early treatment of intestinal ostomy stenosis is particularly important because mild ostomy stenosis can be ameliorated by anal dilatation and severe cases require surgical treatment.

Stoma dilation typically utilizes the patient's fingers or dilators to dilate the stoma; wherein, the finger is adopted to expand the stoma, the finger patient uses the index finger or the little finger to expand the anus, the patient and the family members are guided to wear the finger sleeve after 1-2 weeks after operation, the paraffin oil is coated, the finger sleeve is slowly inserted into the stoma, the finger does not rotate when being inserted so as to avoid the mucosa bleeding, and the finger is kept for 5-10 minutes for 1-2 times/week. Patients with stoma stenosis need to expand the anus every day, start with little finger, generally 2-3 times per day, order deep breathing when patients have a feeling of falling and swelling, change to the index finger and middle finger after slowly getting better, and insist for 3-6 months; however, the finger expansion stoma is mostly performed by medical staff, and patients or family members are difficult to completely master after performing demonstration for a limited number of times, which often causes the unsatisfactory expansion stoma; the prior dilator is easy to cause stoma pollution.
