FAQ

What should be paid attention to in the maintenance and care of laparoscopic surgical instruments?

The following important matters should be paid attention to in the maintenance and care of laparoscopic surgical instruments:

Cleaning and disinfection: After the operation, the laparoscopic instruments should be thoroughly cleaned immediately. First, rinse with running water to remove blood and other dirt, and then soak in a neutral multi-enzyme cleaner for 10 minutes to decompose proteins and organic matter to prevent them from coagulating and adsorbing on the instruments. After that, disinfect with appropriate disinfectants, such as 1/500 or 1000 chlorine-containing disinfectant, or 2% glutaraldehyde for 60 minutes. For metal instruments, rust inhibitors should also be added.

Drying and storage: After cleaning and disinfection, the surface of the instrument should be wiped dry with a soft cloth with strong water absorption to ensure that no water droplets remain. Then, put the instruments in a special instrument cabinet and store them in categories to avoid overlapping and pressure to prevent deformation.

Regular inspection and maintenance: It is recommended to regularly perform maintenance inspections on laparoscopic instruments, including checking the rust and lubrication of the instruments and equipment. If rust is found, rust removal and lubrication should be carried out in time.

Correct handover and record keeping: When handing over, the "four clear" principle should be implemented, that is, hand over, receive, see and count, to ensure that the status and quantity of the instrument can be accurately recorded at each handover.

Anti-rust maintenance: For instrument parts that are prone to rust, such as optical cables, rubber protective covers should be used, and regular inspections should be conducted to see if there are any aging or cracks. If necessary, new protective covers should be replaced.

By following the above steps, the integrity rate of laparoscopic surgical instruments can be effectively improved, their service life can be extended, the safety of surgery can be ensured, and medical accidents caused by instrument problems can be reduced.

What is the best cleaning and disinfection method for laparoscopic surgical instruments?

The best cleaning and disinfection method for laparoscopic surgical instruments should include the following steps:

Pretreatment: First, use a high-pressure water gun to rinse the instrument with a lumen to remove all tissue fragments and other organic matter. Then use soft brushes of various models to wash repeatedly to thoroughly remove all contaminants.

Enzyme washing: Soak the laparoscopic instrument in a solution containing an enzyme detergent for 5 minutes, and use the characteristics of the enzyme to quickly decompose protein and fat contaminants.

Disinfection: According to the "Technical Specifications for Disinfection of the Ministry of Health of the People's Republic of China", for instruments with special contamination, they can be soaked in a disinfectant containing 2000 mg/L of effective chlorine. In addition, a mixture of hydrogen peroxide and potassium iodide can be used for disinfection.

Sterilization: Finally, ethylene oxide sterilization, formaldehyde fumigation, glutaraldehyde soaking or low-temperature peracetic acid disinfection are used for sterilization. These methods can ensure that the instruments are sterile and ensure surgical safety.

Inspection and storage: After cleaning, disinfection and sterilization, the instruments need to be inspected to confirm their sterility, and stored and transported in accordance with regulations.

How to correctly select rust inhibitors and lubricants for laparoscopic surgical instruments?

The following aspects need to be considered to correctly select rust inhibitors and lubricants for laparoscopic surgical instruments:

Select water-soluble lubricating rust inhibitors: According to the "Expert Consensus on Natural Orifice Endoscopic Surgery Notes" and other materials, it is recommended to use water-soluble lubricating rust inhibitors because this type of product can remain stable during high-temperature and high-pressure sterilization and will not affect the sterilization effect of the instrument.

Consider the compatibility and safety of lubricants: The selected lubricant should have good compatibility with human tissues and be non-toxic and non-irritating. For example, 3M Medical Device Lubricant (Strong) is a product that meets these requirements. It uses FDA-certified oil as the base oil, is completely soluble in water, safe, non-toxic and non-irritating.

Pay attention to the concentration and use of lubricants: The concentration and use of lubricants have an important impact on their effectiveness. If the lubricant concentration is too low, it may not effectively protect the surface of the instrument, resulting in corrosion and rust. Therefore, when using lubricants, you should strictly follow the product instructions to ensure the correct concentration and soaking time.

Choose lubricants suitable for specific instruments: Different laparoscopic surgical instruments may require different types of lubricants. For example, some instruments may be more suitable for the use of special lubricants such as bio-enzymes or Ringer's solution. Therefore, when choosing a lubricant, the specific needs of the instrument and the use environment should be considered.

Regular replacement and maintenance: Even if the appropriate lubricant is selected, it needs to be replaced and maintained regularly to maintain its optimal effect. The effect of removing tiny rust stains and spots on reusable surgical instruments can be improved by adding Ruvov Speed ​​Clean Rust Remover and Lubricating Anti-rust Liquid to enhance the flexibility of instruments and increase the service life of surgical instruments.

When selecting anti-rust agents and lubricants for laparoscopic surgical instruments, their water solubility, compatibility with human tissue, safety, concentration and usage methods, as well as whether they are suitable for the needs of specific instruments should be considered.

In laparoscopic surgery, how to effectively avoid the problem of deformation of instruments due to overlap and pressure?

In laparoscopic surgery, the problem of deformation of instruments due to overlap and pressure can be effectively avoided by the following measures:

Reasonable placement of instruments: During the operation, ensure that all instruments are placed in the prescribed position to avoid overlapping, crossing and mixing. In particular, optical fibers and hemostatic instruments with wires should be strictly prohibited from being cut by knives and needles to prevent them from being damaged.

Use incision protectors: Homemade or commercial incision protectors can effectively protect surgical incisions and reduce direct pressure on the incision by instruments, thereby avoiding deformation of instruments.

Reasonable control of clamping force: When using instruments that need to be clamped, care should be taken to control the clamping force to avoid being too small or too large. Too small a clamping force will result in the inability to complete the surgical operation, while too large a clamping force may cause damage to the clamped tissue.

Regular inspection and maintenance: Before and after the operation, all instruments should be inspected and maintained regularly to promptly detect and repair any potential damage or deformation problems.

What special protective measures or technologies are there for the parts of laparoscopic surgical instruments that are prone to rust?

For the parts of laparoscopic surgical instruments that are prone to rust, there are a variety of special protective measures or technologies that can be used:

Choose the right material: Choose a material containing chromium, because chromium can form a dense chromium oxide protective film on the surface of the instrument, which can effectively prevent oxidation and corrosion.

Surface treatment technology:

QPQ technology: This technology changes the internal structure of the metal through a composite treatment process of salt bath nitrocarburizing and salt bath oxidation, followed by polishing and salt bath oxidation, thereby improving its corrosion resistance.
Correct cleaning and pretreatment:

Cleaning steps: After using surgical instruments, they should be cleaned thoroughly immediately to remove organic or inorganic contaminants on the surface and ensure the quality of sterilization.
Avoid soaking in rust removers: If the instrument is already rusty, rust removers should be applied locally to achieve the rust removal effect. It is not recommended to soak in rust removers to avoid further damage to the instrument.
Maintenance and care:

Forming a protective film: Form a protective film on the surface of the instrument to avoid oxidation caused by contact with harmful chemicals in the air, while lubricating the contact parts of the instrument to reduce instrument wear.
Adjust the environment and use corrosion inhibitors: Choose reasonable process operations and equipment structures, and use corrosion inhibitors or cathodic protection measures to prevent corrosion when necessary.
