In the management of laparoscopic surgical consumables, a core decision-making dilemma persists: Should one choose expensive but sturdy reusable stainless steel/titanium alloy reusable cannulas, or opt for disposable high-molecular polymer cannulas that are used once and discarded? This is far from a simple "cost calculation," but rather a deep game involving material science, infection control, hospital operations, and environmental ethics. This article aims to provide a systematic analysis framework for hospital purchasing committees, infection control departments, and financial management departments, which goes beyond the single purchase price.

For Whom It Is Suitable: Decision-Makers in Cost Control and Risk Management

This article is most suitable for the following groups of people to read:

Members of the Hospital Equipment and Consumables Procurement Committee: They need to make balanced decisions among initial cost, long-term cost, clinical risk, and legal risk.

Director of the Hospital Infection Control Office: Focusing on the infection risks related to equipment, he/she is a key role in evaluating the safety of the reprocessing procedures for reusable equipment.

Staff from the Disinfection Supply Center and the Head Nurse of the Operating Room: They are directly responsible for the cleaning, disinfection, sterilization, testing, and inventory management of reusable cannulas, with high costs in terms of manpower and time.

Hospital presidents and chief financial officers who are concerned about hospital operational efficiency: They assess the impact of the two models on the turnover of the operating room, manpower allocation, and total cost from the perspective of the overall hospital operation.

Usage Scenario: Formulation of Consumable Strategies for Medical Institutions of Various Sizes and Types

Large tertiary hospitals with a huge daily surgical volume: It is necessary to assess the massive workload of the reusable equipment processing center, equipment depreciation, personnel costs, and whether the absolute safety of each piece of equipment can be guaranteed.

Medium and small-sized hospitals or specialized hospitals with moderate surgical volume: Evaluate the cost-effectiveness of investing in high-end cleaning and sterilization equipment and hiring professionals versus the cash flow pressure of purchasing disposable products.

Performing special infection surgeries (such as tuberculosis, HIV, hepatitis): One-time equipment can theoretically completely eliminate the risk of cross-infection among patients and simplify the postoperative processing procedures.

Day surgery centers or rapid recovery wards: Have extremely high requirements for surgical efficiency and room turnover rate, and the simplification of the equipment preparation process is of great value.

Comparative Advantage: Multi-Dimensional Deep Competition

Initial Cost vs. Total Life Cycle Cost:

One-time polymer sheath: The single purchase price is clear and relatively low. However, this is a direct cost. Its advantage lies in the absence of subsequent processing costs and the fact that it is discarded after use. Total cost = purchase unit price × number of surgeries.

Reusable stainless steel/titanium alloy sheath: The single purchase price is expensive (possibly several times that of the one-time sheath). However, the total life cycle cost requires complex calculation, including:

Reprocessing cost: High costs for cleaning, disinfection, sterilization (water, electricity, chemical reagents, equipment depreciation) after each use.

Labor cost: Time spent by CSSD professionals in sorting, cleaning, inspection, packaging, sterilization, and distribution.

Maintenance and wear cost: After hundreds of uses, the sealing ring of the precise sheath ages, the valve fails, the puncture core becomes dull, and the tube surface has scratches, which require maintenance or replacement of components. Eventually, there is still a scrap cycle.

Management cost: Inventory management, traceability records, and regular testing costs. Studies have shown that only when the usage times of reusable equipment reach a very high "break-even point," its average cost will be lower than that of one-time products. And this balance point is affected by multiple factors such as the number of surgeries, labor costs, water and electricity fees, etc.

Infection Control Risks: Theoretical Risks vs. Management Risks.

One-time cannula: Offers "theoretical zero risk." Each patient uses brand-new sterile instruments, physically eliminating cross-infection among patients due to incomplete instrument cleaning. This is its most core safety feature, providing clear protection for hospitals at the legal level.

Reusable cannula: Its safety is entirely dependent on the perfection of the hospital's disinfection supply center process. The laparoscopic cannula is complex in structure, featuring narrow valves, springs, and gaps, which are "high-risk instruments" for hiding blood, tissue debris, and biofilms. Any oversight in the cleaning process (such as insufficient flushing pressure, insufficient ultrasonic time, or inadequate scrubbing) or failure in the sterilization process can lead to disastrous consequences. The risk is "management risk," requiring extremely high standards for the hardware, software, and personnel quality of the CSSD.

Performance and Reliability:

Reusable stainless steel/titanium alloy cannulas: Usually machined by high-precision machines, they have excellent mechanical properties. Stainless steel (such as 316L) and titanium alloys possess extremely high strength, rigidity, and wear resistance. They can provide an extremely stable channel during surgery, are not prone to deformation, and the instruments pass through smoothly, with a long-lasting and reliable sealing performance. The high-level reusable cannulas have a solid feel and are preferred by many experienced surgeons.

One-time high-molecular cannulas: Molded from medical-grade engineering plastics (such as polycarbonate, ABS). Their performance has significantly improved over the past decade, but they may have minor differences in terms of hand feel durability, valve durability (especially after repeated replacement of instruments during long surgeries, which may lead to leakage), and compatibility with fine instruments compared to top-level reusable cannulas. However, their advantage lies in being "always new," as each surgery uses a new product with optimal sealing performance.

Operational Efficiency and Environmental Considerations:

One-time products: Significantly simplify the preoperative preparation and postoperative handling procedures. Operating room nurses can simply open the package and use them immediately. After the surgery, they can be disposed of as medical waste, which greatly accelerates the turnover of the operating room and reduces the pressure on the CSSD.

Reusable products: Require complex logistics, cleaning, and sterilization cycles, occupying a large amount of resources in the CSSD, and there is a risk of delaying the surgery due to the failure of timely arrival of the equipment.

Environmental issues: One-time plastic consumables generate a large amount of medical waste, and the handling costs and environmental impact are increasingly attracting attention. Reusable equipment has a natural advantage in sustainable development, but its cleaning process itself also consumes water and energy.

In summary, there is no absolute correct answer when choosing between disposable and reusable laparoscopic puncture sleeves. The optimal solution depends on the specific reality of the medical institution. For large teaching hospitals with a huge volume of surgeries, strong CSSD capabilities, and surgeons with extremely high requirements for instrument feel, investing in top-quality reusable sleeves may be a long-term economical choice. For day surgery centers that emphasize turnaround efficiency, aim to minimize infection risk absolutely, and have higher labor costs, high-performance disposable sleeves are becoming increasingly mainstream and rational choices. The key to decision-making lies in conducting a thorough, data-based "total cost of ownership" analysis and placing the invaluable safety element of infection control at the core of the scale.
