Embodiment 1

[0042] The present embodiment is a kind of nano antibacterial powder, and the preparation process of nano antibacterial powder is as follows:

[0043] S1: Add cetyltrimethoxyammonium bromide and deionized water to a flask equipped with a magnetic stirrer and a constant-pressure low-liquid funnel, add ammonia water, and then keep the temperature at 40°C and the stirring rate at 300r / min Stir for 30min under certain conditions, then cool down to room temperature and add tetraethyl silicate dropwise, control the dropping rate at 1 drop / s, continue stirring for 4h, centrifuge the reaction product, and wash the precipitate with absolute ethanol and distilled water respectively 3 times, after that, filter with suction and place the filter cake in a vacuum drying oven, and dry it to constant weight at a temperature of 40°C to obtain carrier silica; control cetyltrimethoxyammonium bromide, remove The dosage ratio of ionized water, ammonia water and tetraethyl silicate is 0.24g: 140mL:...

Embodiment 2

[0050] The present embodiment is a kind of nano antibacterial powder, and the preparation process of nano antibacterial powder is as follows:

[0051] S1: Add cetyltrimethoxyammonium bromide and deionized water to a flask equipped with a magnetic stirrer and a constant-pressure low-liquid funnel, add ammonia water, and then keep the temperature at 40°C and the stirring rate at 500r / min Stir for 50min under certain conditions, then cool down to room temperature and add tetraethyl silicate dropwise, control the dropping rate at 1 drop / s, continue stirring for 5h, centrifuge the reaction product, and wash the precipitate with absolute ethanol and distilled water respectively 5 times, then suction filtered and placed the filter cake in a vacuum drying oven, and dried to constant weight at a temperature of 50°C to obtain carrier silica; control cetyltrimethoxyammonium bromide, remove The dosage ratio of ionized water, ammonia water and tetraethyl silicate is 0.24g: 140mL: 4mL: 1.22...

Embodiment 3

[0058] This embodiment is an enterostomy knife with easy operation and good stoma effect, which includes a handle 101, a rotating shaft 102, a cutting board 103, and a circular stoma blade 104. A rotating shaft 102 is installed through the middle of the two handles 101. Rotately connected with the rotating shaft 102, the top of one handle 101 is equipped with a cutting board 103, and the top of the other handle 101 is equipped with a round stoma blade 104, the round stoma blade 104 is cylindrical, and the round stoma blade 104 is connected to the cutting board 103 is a matching member;

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...
