What are the fault diagnosis and repair methods for laparoscopic surgical instruments?

The fault diagnosis and repair methods for laparoscopic surgical instruments involve multiple aspects, including the identification of common faults, cause analysis, diagnostic methods, and targeted maintenance measures. The following is a detailed analysis:

Common fault manifestations:

Display camera system failure: such as the black screen phenomenon of the monitor, which may be caused by the display, the power connector of the cold light source system, the camera cable connector falling off, the poor contact and damage of the cold light source system bulb, etc.
The monitor image is dark or has continuous wavy patterns, which may be related to the use of high-frequency electric knife.

Fault cause analysis:

Assembly error: Due to the complex structure, precision and smallness, many spare parts, and many brands of laparoscopic surgical instruments, assembly errors are prone to occur.

Improper use: such as avoiding violence during use during surgery, correct disinfection and sterilization methods, and checking whether the instruments are damaged when tidying up after surgery.

Diagnostic method:

Preoperative careful inspection: Carry out a careful inspection of the equipment, and always have spare parts such as the cold light source system, just in case.

Alternative method maintenance: If the monitor image is dark and distorted, it can be repaired by the substitution method.

Repair measures:

For display camera system failure, it can be solved by replacing damaged parts or reconnecting the power connector and camera cable connector.
For monitor image problems, the image quality can be improved by adjusting settings or replacing related parts.
For insufflator failure, it can be solved by checking the pressure alarm system and adjusting the pressure setting.

Daily maintenance:

Cleaning: Laparoscopic instruments are mostly cleaned manually. When cleaning, various instruments should be disassembled one by one into the smallest unit, and cleaned with running water in the initial washing pool.
Maintenance: Laparoscopic equipment should be placed on the laparoscopic instrument table. The surface should be cleaned and covered with dust cover before and after each use.
Through the above steps, the failure of laparoscopic surgical instruments can be effectively diagnosed and repaired to ensure the smooth progress of the operation.

What are the common causes of laparoscopic surgical instrument display camera system failure?

The common causes of laparoscopic surgical instrument display camera system failure mainly include the following points:

No image display: This is one of the most common failures, which may be due to problems with the camera, video cable or monitor itself. For example, when the camera is turned on, if the camera is plugged in and the video cable is connected, but no image is displayed on the monitor, there may be a problem with the camera or the video cable.

Blurred image: Blurred images may be caused by damage to the optical fiber or a faulty signal converter. Optical fibers and signal converters are important parts of the camera system, which are responsible for transmitting image signals from the camera to the monitor. If there is a problem with these components, the image will become blurred.

Image interference: This situation is usually manifested as horizontal strips of clutter or other interference signals on the monitor. The main reason may be electromagnetic interference from external high-frequency equipment or insufficient shielding of the video transmission line. For example, when an electric knife is used during surgery, electromagnetic interference may be generated, causing interference in the image.

Image color distortion: This may be caused by aging or damage to certain components in the camera system. For example, aging of the camera or optical fiber may cause image color distortion.

Stripe artifacts: When stripe artifacts appear in the photographic image, it may be due to interference signals in the camera. The main consideration is whether the shielding function of external high-frequency equipment interference and the transmission function of the collected information are faulty.

Common causes of laparoscopic surgical instrument display camera system failure include no image display, blurred image, image interference, image color distortion, and strip artifacts.

How to correctly assemble laparoscopic surgical instruments to avoid failures?

To correctly assemble laparoscopic surgical instruments to avoid failures, you need to follow the following steps and precautions:

Special person responsible: Make sure that there is a special person responsible for the storage and maintenance of laparoscopic surgical instruments to ensure the integrity and safety of the equipment.

Regular inspection and maintenance: The responsible nurse should conduct regular inspections of laparoscopic instruments every week, including checking the rust and lubrication of the instruments and equipment, and promptly remove rust and lubricate the rust. In addition, the equipment department engineer should also regularly check the operation of the instrument and local inspections, dustproof and refuel the instruments and equipment, cover the protective cover after cleaning the instruments, and check whether the wheels of the stainless steel mobile frame are installed.

Correct cleaning and disinfection: After each cleaning, routine maintenance should be performed on laparoscopic surgical instruments to ensure the good performance of all parts of the instrument and extend its service life. Especially for external equipment such as laparoscopic displays, full-time nurses are responsible for terminal disinfection and maintenance. First, wipe the surface of the equipment with medical disinfectant wipes to remove splashed blood and attached dust.

Disassemble according to the instructions: When disassembling laparoscopic surgical instruments, you must strictly follow the instructions and do not disassemble them at will to avoid damage to the instruments or loss of key components.

Master the connection method and operation method: Circulating nurses should be proficient in the connection method, usage precautions and correct operation methods of various instruments, and be able to eliminate some common faults, so as to be proficient in assembling instruments and cooperating with surgery.

Protect sharp instruments: For sharp instruments, such as puncture cones and converters, rubber protective covers should be put on. If they are aging or cracked, they should be replaced in time to avoid leakage during surgery and affect the pneumoperitoneum effect.

What are the faults caused by improper use of laparoscopic surgical instruments and their preventive measures?

Improper use of laparoscopic surgical instruments may lead to a variety of complications, including ischemic stenosis of blood vessels and bile ducts caused by electrothermal damage, and perforation of hollow organs caused by the "skin effect" of high-frequency current. In addition, instrument assembly errors can also lead to problems during surgery, such as accidental injury to blood vessels, bile ducts or intestinal tracts, which will not only prolong the operation time, but may also endanger the patient's life.

To prevent these failures and their complications, the following measures can be taken:

Improve the professional knowledge and skills of doctors: Doctors who use thoracic and laparoscopic surgery should have a certain basic knowledge of optics and electricity, so that they can better use equipment and instruments for surgery, and be able to troubleshoot the equipment and instruments as soon as possible when they fail.

Standardized treatment measures: Develop standardized treatment measures to ensure the smooth progress of laparoscopic surgery. This includes maintenance and inspection of surgical instruments to ensure that they are in good condition before surgery.

Preventive maintenance plan: Develop targeted preventive maintenance plans and training programs to transform passive fault repairs into active preventive maintenance, thereby reducing clinical surgical risks.

Strengthen nursing care: Strengthen nursing work for laparoscopic surgery to reduce unnecessary hazards. Nursing staff should be familiar with the use and precautions of surgical instruments so that they can promptly discover and correct improper use during surgery.

What is the application and effect of alternative maintenance in the maintenance of laparoscopic surgical instruments?

The application and effect of substitution method maintenance in the maintenance of laparoscopic surgical instruments are as follows:

Substitution method maintenance is mainly used for the maintenance of various medical instruments such as endoscopes, electronic laparoscopes, fiberscopes, etc. The services provided by Guangzhou Chuangyi Medical Technology Co., Ltd. include rigid endoscope maintenance, electronic laparoscope maintenance, electronic scope maintenance, fiberscope maintenance, camera system maintenance, power system maintenance, ultrasonic knife maintenance, etc.

Substitution method maintenance improves instrument management through modular assembly, avoids downtime caused by waiting for maintenance, and thus improves surgical efficiency and safety. In addition, substitution method maintenance can also extend the insulation layer, increase safety during use, and reduce the risk of burns in the replacement part during electrotherapy.

Compared with traditional laparoscopic surgical instruments, substitution method maintenance can overcome some limitations. For example, the application of the da Vinci surgical robot has overcome the shortcomings of traditional laparoscopic surgical instruments such as small rotation angle, large blind area of ​​vision, and low accuracy to a certain extent. Although this does not directly explain the effect of substitution method maintenance, it shows the potential of modern technology in improving the performance of surgical instruments.

Replacement maintenance has a wide range of applications in the maintenance of laparoscopic surgical instruments, and through modular assembly and other technical improvements, it has significantly improved surgical efficiency and safety.
