Intestinal stoma knife easy and convenient to operate and good in stoma effect

Abstract

The invention discloses an intestinal stoma knife easy and convenient to operate and good in stoma effect, and relates to the field of medical instruments. The intestinal stoma knife comprises a handle, a rotating shaft, a cutting board and a circular stoma blade. When the intestinal stoma knife is used, through mutual cooperation of the cutting board and the circular stoma blade, the cylindrical circular stoma blade exerts pressure on the skin, direct stoma is achieved, and a uniform circular incision is formed. Operation is easy and convenient, and the stoma effect is good. In the preparation process of the intestinal stoma knife, nano-antibacterial powder is also prepared, the nano antibacterial powder has excellent antibacterial activity through silver ions, the nano antibacterial powder can effectively interfere with the normal physiological functions of microorganisms and inhibit the growth of the microorganisms, and the prepared enterostomy knife has a good antibacterial effect, so that the probability of surgical infection is reduced. According to the nano antibacterial powder, the intestinal stoma knife has good hydrophobic and oleophobic properties through a large number of C-F bonds, so that blood adhesion during an operation is avoided, the situation that the intestinal stoma knife is polluted and difficult to clean is avoided, and cross infection is avoided.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an enterostomy knife with easy operation and good stoma effect. Background technique [0002] The morbidity and mortality of colorectal cancer are relatively high, ranking third and fifth among all malignant tumors, and showing a rising trend. Cases of rectal cancer in my country account for about 60% of the total number of cases of colorectal cancer. However, 70-80% of rectal cancer cases are middle and low rectal cancers, and middle and low rectal cancers often require temporary or permanent enterostomy. Enterostomy requires a circular incision on the abdominal wall, and the diameter of the incision is adapted to the diameter of the intestinal tube. , generally about 3cm, too large or too small incision will have adverse effects on defecation after enterostomy; [0003] When making an enterostomy, it is necessary to make a circular incision on the abdominal wall skin, and care mus...

AI Technical Summary

Problems solved by technology

[0003] When making an enterostomy, it is necessary to make a circular incision on the abdominal wall skin, and care must be taken to protect the abdominal wall muscle and its deep tissues. It is time-consuming to make a circular incision with a common blade, and the size and size of the incision will vary depending on the proficiency of the operator. Circular incisions with different shapes lead to incompatibility between the incision and the stoma intestine, which affects the effect of the stoma, and the antibacterial properties of ordinary blades are poor, and the bacteria carried are easy to wound infection. The adhered blood is difficult to clean during the operation, which will affect the next operation. usage of;
