FAQ

What is the service life and replacement cycle of urological surgical instruments?

The service life and replacement cycle of urological surgical instruments vary depending on the specific equipment and usage, but some general information can be summarized.

Rigid ureteroscopes and nephroscopes: These devices usually have clear maintenance service requirements, such as a warranty period of more than 6 months, and require regular repairs and maintenance to ensure their normal operation. In addition, these devices may require frequent maintenance and inspections in actual use to avoid failures.

Electrosurgical instruments: Due to their precision and difficulty in cleaning, the cleaning, disinfection and maintenance of these instruments are particularly important. Studies have shown that qualified cleaning is a prerequisite for successful sterilization, so for these expensive and difficult-to-clean instruments, their service life will be affected by the quality of cleaning.

Other surgical instruments: Tools such as screwdrivers and retractors have an expected service life of 250 cycles and 5,200 cycles, respectively. This shows that different types of surgical instruments have different durability standards.

Urethral exposure (AUS) devices: Some studies mentioned in the literature indicate that the average service life of such devices is 56 months, and the service life can be significantly extended by modifying the design.

Laparoscopic systems: Devices that contain replaceable parts or accessories should clearly state the product's service life and the replacement cycle of replaceable parts.

Overall, the service life and replacement cycle of urological surgical instruments depend on many factors, including device type, frequency of use, maintenance, and design improvements. Detailed instructions for use and maintenance manuals for each device usually provide more specific guidance.

What are the specific repair and maintenance cycles for rigid ureteroscopes and nephroscopes?

The repair and maintenance cycles for rigid ureteroscopes and nephroscopes vary among different service providers.

The repair and maintenance cycles for rigid ureteroscopes and nephroscopes range from 3 to 10 working days, depending on the specific situation of the service provider and the device.

What are the comparative studies on the service life of electrosurgical instruments under different cleaning qualities?
There is currently information on the comparative studies on the service life of electrosurgical instruments under different cleaning qualities. The following is a detailed analysis:

The study by Qi Huizhen et al. showed that the cleaning qualification rate of electrosurgical instruments can be significantly improved from the original 81.8% to 98.5% by using mannitol flushing solution and improving manual cleaning methods. This shows that the improvement of cleaning quality has a direct impact on the maintenance of instruments and the extension of their service life.

Another study selected 210 electrosurgical instruments after urological surgery as experimental subjects, divided into a control group, observation group 1 and observation group 2, with 70 pieces in each group. The results showed that the use of different pretreatment methods (such as foaming machine pretreatment) can effectively improve the cleaning effect, which may affect the service life of the instrument.

The study of the Hebei Provincial Health Commission pointed out that there are a large number of organic pollutants such as protein, fat, and blood on the surface of electrosurgical instruments after surgery. If these pollutants are not completely removed, it will not only increase the risk of infection for patients, but also corrode the instruments and shorten their service life. Therefore, ensuring the cleaning quality of instruments is the key to extending their service life.

The cleaning quality is also affected by the operating level and management mechanism of professional cleaning personnel. Qi Huizhen et al. emphasized the importance of cultivating professional cleaning personnel and improving management mechanisms to ensure cleaning quality and improve the sterilization effect of instruments.

The use of electrosurgical cleaning tablets can further improve cleaning efficiency and have anti-corrosion functions, thereby extending the service life of electrosurgical devices and reducing maintenance costs.

Kozarek RA et al. conducted an in vitro evaluation of the reusability and metal wire integrity of sphincterotomes and found that after manual cleaning and ethylene oxide treatment, most instruments were able to maintain integrity and sterility, but some of them had metal wire breakage after multiple uses. This shows that the cleaning quality directly affects the durability and service life of the instrument.

Comprehensive data shows that different cleaning qualities have a significant impact on the service life of electrosurgical instruments.

What is the difference between the expected service life of screwdrivers and retractors and their actual use?

The difference between the expected service life of screwdrivers and retractors and their actual use is mainly reflected in the following aspects:

Material and manufacturing quality:

Screwdrivers are usually made of high-quality materials, such as carbon steel or alloy steel, with high durability and fatigue resistance. However, if used improperly or not maintained in time, it may cause premature wear of the screwdriver, affecting its service life.
Retractors are mostly made of high-quality stainless steel and other materials to ensure their sturdiness and reliability. Nevertheless, frequent use and disinfection may still cause certain wear and tear on the retractor, which requires regular maintenance and care to extend its service life.
Frequency and intensity of use:

Screwdrivers may face different usage scenarios and intensities in daily use, which directly affect their service life. For example, the average life of an electric screwdriver is about two years when used for 4 hours a day; while a good helper electric screwdriver can be used for 3-5 years under normal use. If it is used improperly or not maintained in time, its service life may be shortened.
As a medical device, although the retractor is designed to have a long service life, it is also necessary to avoid excessive wear and improper operation in actual use to reduce the frequency of replacement and repair.
Maintenance and care:

Screwdrivers require regular maintenance measures such as lubrication, cleaning and calibration to maintain their normal operation and extend their service life. Proper maintenance and care can maximize the performance of electric screwdrivers and improve work efficiency.
Retractors also require regular maintenance and care to ensure their normal operation and extend their service life. Choosing the right retractor and performing proper maintenance according to usage is the key.
The difference between the expected service life of screwdrivers and retractors and their actual use mainly lies in aspects such as material quality, frequency and intensity of use, and maintenance and care.

How can design improvements of AUS devices significantly extend their service life?

Measures to significantly extend the service life of AUS devices can be considered from multiple aspects:

Reduction in mechanical failure rate: According to
, after the introduction of narrow straps, the non-mechanical failure rate dropped from 17% to 9%, while the mechanical failure rate dropped from 21% to 8%. This shows that mechanical failure rates can be effectively reduced through design improvements, such as using more durable materials or optimizing the design to reduce mechanical stress.

Avoiding excessive use and proper storage: The importance of avoiding excessive use of equipment and proper storage is emphasized. This means that when designing AUS equipment, the durability of the equipment and the convenience of user operation should be taken into account to reduce early damage caused by improper use.

Regular maintenance: It is pointed out that regular cleaning, lubrication, tightening screws, and replacement of parts are key to extending the life of the equipment. Therefore, the design of AUS equipment should be easy to maintain, such as using parts that are easy to disassemble and clean, or pre-setting maintenance channels in the design.

Avoid erosion and atrophy:
It is mentioned that part of the cause of mechanical failure is due to urethral atrophy and cuff erosion. Design improvements may include using more corrosion-resistant materials or designing cuffs that are more in line with human anatomy to reduce the occurrence of these complications.

Improve design with simulation technology: It is mentioned that the use of simulation technology can improve the design of medical equipment to ensure patient safety, efficiency and effectiveness. This means that in the design stage of AUS equipment, potential failure modes can be predicted through simulation analysis, and design optimization can be performed accordingly to improve the reliability and life of the equipment.

How long is the replacement cycle of replaceable parts or accessories in laparoscopic systems?

The specific replacement cycle of replaceable parts or accessories in laparoscopic systems is not directly given. However, it is mentioned that in the technical review points of laparoscopic surgical systems, for devices containing replaceable parts or accessories, the replacement cycle needs to be studied, and the product's service life, the replacement cycle of replaceable parts, and the product care and maintenance methods should be clearly stated in the instructions and labels.

The data show that the replacement cycle of replaceable parts or accessories in laparoscopic systems should be determined according to the specific product characteristics, and this information should be provided by the manufacturer in the product manual. Because different models and brands of laparoscopic systems may have different designs and usage requirements, the specific replacement cycle may vary from product to product.
