Problems solved by technology

However, this method makes the structure of the scalpel complicated, inconvenient to use and very expensive
[0003] Although harmful substances such as pus and blood stains adhere to surgical instruments and cause great troubles for doctors to perform operations, the current research and investment in this area are mainly concentrated on cleaning equipment, which not only cannot be solved from the source, but also costs more. high
At present, the blood removal treatment of surgical instruments is mainly through changing the structure of surgical instruments, which increases the complexity and difficulty of use of the instruments, and the effect is not ideal, and it is not easy to form industrialization

Embodiment Construction

[0015] Such as figure 1 As shown, first use high temperature resistant, corrosion resistant, low density aseptic carbonized stainless steel to make the surgical instrument substrate, and use metallographic abrasive paper to clean and polish the surgical instrument substrate so that the surface is free of any impurities such as rust. Then put it into the ethanol solution and ultrasonically vibrate for 20-30 minutes, the frequency is 20-25Khz. with HNO at room temperature 3 / H 2 o 2 The mixed solution is soaked to obtain a rough surface structure, which is a columnar structure with a diameter of 10-20 microns and an interval of about 20-30 microns. Immerse the device with a rough surface structure into a hexane solution containing stearic acid, take it out after soaking for 24 hours, and place it in the air to dry for 2-3 hours to obtain a surface structure similar to that of a lotus leaf with hydrophobic and hemophobic properties. self-cleaning bloodless surgical instrumen...

Abstract

The invention discloses a preparation method for a self-cleaning bloodless surgical instrument. The preparation method for the self-cleaning bloodless surgical instrument comprises that using a piece of metallographical abrasive paper to clean and brighten a base body of the surgical instrument, removing the impurity, carrying out chemical etching method to obtain the rough surface structure of the base body of the surgical instrument, and combining stearic acid molecules with an oxide layer of the base body of the surgical instrument to firm a micro-surface structure. According to the preparation method for the self-cleaning bloodless surgical instrument, the hydrophobic and blood-dredging micro-structure is formed at the surface of the surgical instrument, so that the body fluid and the blood are difficult to adhere to the surface of the surgical instrument.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a method for preparing a self-cleaning bloodless surgical instrument, in particular to the use of the surgical instrument herein. However, it should be understood that this method is also applicable to other medical devices. In particular, the medical devices mentioned in this article not only include all medical-related devices such as surgery, nursing, biopsy, and dentistry, but also devices that only need to be sterilized. Such as kitchen tools, hairdressing tools, etc. Background technique [0002] The surgical instruments of the prior art are easily adhered by pus, blood stains and other harmful substances during the operation, which causes great troubles for doctors to perform operations. For example, when a doctor performs surgery with a scalpel, the blood and other body fluids on the knife will affect the doctor's judgment on the position of the tip and blade, and hind...
