preparation example Construction

[0025] The preparation method of the blood-stained self-cleaning surgical instrument of the present invention comprises the following steps:

[0026] S1. Degreasing, polishing and cleaning the parts to be treated of the surgical instruments;

[0027] The material of the metal substrate of the part to be treated of the surgical instrument is one of stainless steel, titanium alloy, ceramics, polymer materials and plastics. After drying, perform mechanical polishing to remove the oxide layer, then clean with deionized water and ultrasonic waves, and then blow dry again. The mechanical polishing is to polish with abrasives or sandpaper above 800#, and the ultrasonic cleaning time is 4 to 6 minutes.

[0028] S2. After filtering the coating containing nano-ceramic particles with a filter screen, it is evenly mixed with the lubricant;

[0029] The diameter of the nano-ceramic particles is 10-100nm, the nano-ceramic is one or more mixtures of alumina ceramics, silicon nitride ceramic...

Embodiment 1

[0037] S1. First, clean and degrease the metal stainless steel plate of the surgical instrument with a size of 20mm×20mm×2mm in anhydrous ethanol, and after drying, polish it with 800# and 1500# sandpaper to remove the surface oxide layer, and then remove the polished surface The stainless steel plate was cleaned with a large amount of deionized water, then ultrasonically cleaned for 5 minutes, and dried with a hair dryer.

[0038] S2. Filter the silicon carbide ceramic coating solution with a nanoparticle diameter of 100nm through a 400-mesh filter, and mix it with simethicone oil with a kinematic viscosity of 10cs in a mass ratio of 1:1, and stir evenly.

[0039] S3. Immerse the pretreated surgical instrument to be treated in the paint, fully soak it, and then let it stand at an angle to form a uniform coating on the surface, and let it stand at an inclination angle of 20° for 30 minutes, and tilt it for 20° ° Allow excess paint to flow off the surface for a stable coating. ...

Embodiment 2

[0042] S1. First, clean and degrease the metal titanium alloy plate of the surgical instrument with a size of 20mm×10mm×2mm in anhydrous ethanol. After drying, sand it with 800# and 1500# sandpaper to remove the surface oxide layer, and then polish it The titanium alloy plate was cleaned with a large amount of deionized water, then ultrasonically cleaned for 5 min, and dried with a hair dryer.

[0043] S2. Filter the aluminum oxide ceramic coating solution with a nanoparticle diameter of 50nm with a 400-mesh filter, and mix it with perfluoropolyether oil in a mass ratio of 1:1, and stir evenly.

[0044] S3. Immerse the pretreated surgical instrument to be treated in the paint, fully soak it, and then let it stand at an angle to form a uniform coating on the surface, and let it stand at an inclination angle of 20° for 30 minutes, and tilt it for 20° ° Allow excess paint to flow off the surface for a stable coating.

[0045] S4. Take out the pre-soaked surgical instrument to be...

Abstract

The invention relates to the technical field of medical equipment and particularly discloses a self-cleaning surgical instrument incapable of being stained with blood and a production method thereof.The production method includes: subjecting the to-be-processed part of a surgical instrument to oil removing, polishing and cleaning, using a filter screen to filter coating containing nano ceramic particles, evenly mixing the coating with a lubricating agent, coating the to-be-processed part of the surgical instrument with the mixed coating, and taking the surgical instrument out of the mixed coating to allow the coating layer at the to-be-processed part of the surgical instrument to become ceramic. The self-cleaning surgical instrument has self-cleaning performance and stain resistance to human blood and tissue fluids, can repel foreign matter such as blood stain and dust, can effectively reduce sterilizing and cleaning time during surgery so as to shorten surgery time and relieve patient pain, can prevent the other parts of a human body from being infected by blood or tissue stains on the surgical instrument and can lower the possibility of complications.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a blood-stained self-cleaning surgical instrument and a preparation method thereof. Background technique [0002] With the continuous development of science and technology and the improvement of people's living standards, the public's requirements for medical treatment have gradually increased, and their requirements for treatment quality and quality of life have increased significantly. They not only care about the treatment results, but also care about the cleanliness, damage, and Safety, comfort and minimal invasiveness. Operation is the main treatment method of surgery in the medical field, and scalpel is a kind of medical instrument commonly used in surgery, which is used to cut the patient's diseased part in the operation process, to maintain the health of the patient. [0003] Blood and interstitial fluid often stain the knife during the operation, which will ...
