Product Application - Reasons for Medical Product Failure
Corrosion
Wear and tear
Every step in the use and handling of surgical instruments, including usage, pretreatment, soaking, cleaning, disinfection and sterilization, etc., can easily lead to surface wear, peeling and rusting of the instruments, causing damage to the instruments.
Main pain points
Dry storage of the instrument after use makes cleaning difficult and causes damage when scrubbing.
If the blood and other contaminants on the instruments are not initially wiped off, it will cause corrosion to the instruments, making them rust and thus affecting their service life.
Scissors, chisels and other tools that require sharpness will have their cutting edges become dull after repeated use, cleaning and disinfection, and will not be used properly in the future.
The shiny metallic appearance of the instruments can easily cause medical staff to be dazzled during long surgical procedures, leading to mistakes.

The advantages of coatings such as DLC and hard Cr in medical devices
| Main advantages | |
| Production | 1. DLC and hard Cr are highly hard and wear-resistant, preventing scratches on the surface of the instruments during the cleaning process and further inducing corrosion. 2. The film layer is uniform and smooth, which does not affect the opening and closing of the scissors and maintains the sharpness of the cutting edge. 3. The coating can be removed without damaging the substrate, and medical devices can be reused. |
| Productivity | 1. The reuse of equipment can effectively reduce production costs. 2. Both the black shiny DLC coating and the white hard Cr coating can effectively prevent medical staff from being dazzled. |
| Terminal products | 1. Significantly increase the lifespan of various medical products and other terminal products. 2. Reduce the frequency of return repairs for terminal products. |
