Description

Edging port chassis cutting die

Technical Field

The utility model relates to a cutting die for an ostomy base plate capable of grinding edges, and belongs to the technical field of medical instrument design.

Background

The intestinal stoma is commonly known as "artificial anus", which is an artificial diversion of the anus for medical purposes, such as the treatment of intestinal diseases, and suggests a passage for the intestinal tract to communicate with the abdominal body surface, the opening of which is a stoma through which the stool and urine are discharged from the body. At present, the incidence rate of large intestine tumors in China is increased year by year, and patients with low rectal cancer are increased day by day, and more patients need to be treated by enterostomy. The enterostomy treatment requires that a section of intestinal tube is pulled out from the belly and is sewn at a cut on the belly, so that the patient can conveniently excrete the excrement, but because the intestinal excrement of the patient is directly excreted from the intestinal canal without being controlled by the anal sphincter, an ostomy bag is required to be attached outside the stoma to collect the excrement. The ostomy bag is intended to be mounted on an ostomy tray during use, and the opening in the ostomy tray needs to be suitably cut in order to allow a better collection of waste. The cutting of the stoma chassis is mainly performed by scissors, due to the fact that the eyesight of a plurality of middle-aged and elderly people is reduced, the flexibility of the two hands of some patients is not good, the stoma chassis is difficult to cut by the scissors, and the improper cutting of the stoma chassis can cause excrement leakage, cause skin damage and cause physiological and psychological trauma to the patients.

In order to overcome the problems, the unit provides the stoma base plate cutting die (with the application number of CN201921269455.8), the cutting die can be used for cutting without scissors, the more accurate stoma base plate size can be formed by the cutting die, the size accuracy of the die is better than that of manual cutting, the pain of a plurality of stoma patients with inflexible hands and poor eyesight is relieved, the labor and time of the stoma patients are saved, good news is brought to the stoma patients, and the life quality of the stoma patients is improved. However, the cutting die has the following defects in clinical use: 1. the intestinal stoma of a patient has different sizes, different specifications can be cut clinically, and the mould body needs to be replaced at the moment, so that the operation is complicated; 2. the edge of the punched hole is sharp, and the surface of the enterostomy is easily abraded to cause infection.
