Pre-sterilization cleaning is the most critical stage in preparing laparoscopic instruments for reuse. During this process, blood, protein residues, tissue fragments, pharmaceutical residues, and detergent residues are completely removed from the instrument surfaces.

The procedure for pre-sterilization cleaning is regulated by applicable sanitary and epidemiological requirements, the manufacturer's instructions for the medical device, and the recommendations provided by the detergent manufacturer. For each laparoscopic instrument, factors such as design features, internal channels, articulated joints, detachable components, and construction materials must be taken into account.

The mandatory stages of pre-sterilization cleaning include:

• Disassembling the instrument, if permitted by its design;

• Soaking the instruments in a detergent solution while observing the recommended concentration and exposure time;

• Mechanical cleaning of working surfaces, joints, locking mechanisms, and internal channels using specialized brushes, channel cleaners, and other appropriate cleaning tools;

• Rinsing the instruments thoroughly to remove detergent residues;

• Final rinsing with purified water;

• Complete drying before the instruments are transferred for sterilization.

For instruments with complex geometries, narrow lumens, or hard-to-reach areas, ultrasonic cleaning systems may be used. This cleaning method should always be applied in accordance with the recommendations provided by both the equipment manufacturer and the medical device manufacturer.

After cleaning has been completed, the quality of the process must be verified. Special chemical tests are used to detect residual blood, protein contamination, and detergent residues. If the results fail to meet the required standards, the entire cleaning process must be repeated from the beginning.

Methods of Sterilizing Laparoscopic Instruments

Once pre-sterilization cleaning has been completed, the instruments proceed to sterilization. The sterilization method is selected according to the instrument's design, construction materials, and the manufacturer's recommendations. Since no single sterilization protocol is suitable for every laparoscopic instrument, the technical documentation should always be reviewed before use.

Several sterilization methods are commonly used in modern healthcare facilities:

• Steam sterilization. Performed in an autoclave using saturated steam under pressure. This is the standard method for most reusable stainless steel surgical instruments.

• Low-temperature hydrogen peroxide plasma sterilization. Recommended for instruments that cannot withstand high temperatures.

• Gas sterilization. Used for specific types of medical devices that are incompatible with steam sterilization.

• Chemical sterilization. Applied only in situations permitted by applicable regulations and the manufacturer's instructions.

Each sterilization method has its own requirements regarding instrument preparation, sterilizer operating parameters, and post-sterilization storage. Failure to comply with these requirements may reduce sterilization effectiveness or damage the instrument's functional surfaces.

Choosing the Appropriate Sterilization Method for Different Types of Laparoscopic Instruments

When selecting a sterilization method, the instrument's design should always be the primary consideration. Standard stainless steel instruments without heat-sensitive components generally tolerate steam sterilization and are routinely processed using this method due to its reliability and high throughput.

Instruments containing polymer components, electrical insulation, optical systems, or other heat-sensitive materials require low-temperature sterilization technologies. In such cases, hydrogen peroxide plasma or gas sterilization should be used strictly in accordance with the manufacturer's operating instructions.

Before sterilizing any instrument, healthcare personnel should verify that the selected sterilization cycle complies with the manufacturer's specifications. Using an inappropriate sterilization method may result in component deformation, damage to protective coatings, and a significant reduction in the instrument's service life.

Quality Control of Cleaning and Sterilization

The final stage of the reprocessing cycle is quality control. During the cleaning stage, instruments are inspected for residual blood, protein contamination, and detergent residues. Following sterilization, compliance with the sterilization cycle is verified using chemical and biological indicators. The integrity of sterile packaging and the accuracy of labeling are also inspected.

Each instrument should additionally undergo a visual inspection before use. Working tips, articulated joints, cutting components, and insulation must be free from corrosion, cracks, mechanical damage, or signs of excessive wear. Any instrument with identified defects must be removed from service until the issue has been corrected.
