FAQ
Laparoscopic equipment may have a variety of failure phenomena during surgery, which will not only affect the smooth progress of the operation, but also may cause the operation to be complicated or even interrupted. The following are some common failure phenomena and their causes:
Image interference: Horizontal strip clutter appears on the monitor, affecting the surgical field of view.
Insufflator failure: Damage to the connecting tube at the CO2 outlet of the insufflator will cause the pressure to be too low, thus affecting the normal progress of the operation. Replacing the outlet connecting tube can solve this problem.
Camera failure: Camera failure may include problems such as severe image flickering, which requires replacement of original new accessories and repair by professional engineers.
Bipolar cable and forceps failure: Failures of these instruments account for 31% of the total number of laparoscopic examination failures, mainly due to problems with the instrument itself or improper combination of components.
The cold light source bulb is not bright: The cold light source bulb is not bright, which may be caused by damage to the bulb itself or poor power connection.
Through these measures, the failure rate of laparoscopic equipment in surgery can be effectively reduced to ensure the smooth progress of surgery.
The common causes and solutions for the black screen of the laparoscopic monitor are as follows:
The solution is to check and ensure that all power cords and signal input cables are firmly connected, and replace damaged parts if necessary.
Equipment failure: Failure of the high-frequency electrosurgical knife or the laparoscope itself may also cause a black screen. The solution includes keeping the high-frequency electrosurgical knife away from the laparoscopic camera and signal transmission line to reduce interference.
Monitor sleep mode: If the monitor is not used for a long time, the monitor may automatically switch to sleep energy-saving mode and the screen will be black. The solution is to restart the monitor or adjust the power management settings.
Aging of internal components: The electronic components inside the monitor (such as capacitors, transistors, etc.) may age and fail over time, resulting in unstable working conditions and causing a black screen. The solution is to regularly maintain and replace aged internal components.
Poor heat dissipation: Poor heat dissipation may also accelerate the aging of internal components and increase the probability of a black screen. The solution is to ensure good heat dissipation conditions for the monitor to avoid overheating.
Other mechanical problems: Sometimes simple mechanical operations can also solve the problem, such as patting the monitor with your hands.
Methods to effectively prevent laparoscopic image interference and improve the quality of surgical field of view include the following aspects:
Use high-definition imaging technology: The use of 4K imaging technology can greatly improve the clarity of the image, increase the recognition of intraoperative microstructures, and make anatomical freedom more precise, thereby reducing intraoperative bleeding.
Apply three-dimensional imaging technology: 3D laparoscopes can provide clearer stereoscopic vision during surgery, which helps to improve the quality of surgical field of view and surgical efficiency.
Introduce artificial intelligence technology: Through artificial intelligence technology, new field of view quality indicators (such as ESFCI) can be provided for endoscopic surgery, which not only improves the efficiency and safety of surgery, but also provides researchers with a new method to evaluate and improve the quality of field of view during endoscopic surgery.
Improve operating techniques: In laparoscopic surgery, the quality of surgical field of view can be further improved by improving the operating techniques of the observation mirror and electrode hook.
Use fluorescent imaging technology: Fluorescent imaging technology can detect the accuracy of diseases and important tissues during surgery, providing an efficient method that is seamlessly integrated into the normal working process of the operating room.
Optimize equipment configuration: For example, in a 4K laparoscopic system, the recommended insufflator flow rate is 40 L/min, and an exhaust device is added to increase the flow of gas in the abdominal cavity to reduce the aerosol interference generated by the intraoperative energy device.
The repair techniques for the damaged connecting tube at the CO2 outlet of the laparoscopic insufflator mainly include the following aspects:
Replace damaged or severely worn accessories (pipelines) in time: This is the most direct and effective method to ensure the safety and normal operation of the equipment.
Leak detection: After the piping is connected, the piping should be tested for leaks to ensure that there are no impurities in the pipeline.
Acoustic imager application: For the investigation and treatment of leak points, an acoustic imager can be used to accurately locate the leak point. This method can quickly find the source of the leak in visible light, which is convenient for timely repair.
The quick diagnosis and repair methods for laparoscopic camera failure are as follows:
Check the camera connection: First, check whether the camera connection has any breakpoints.
Clean the camera lens: If the image is too dark or unclear, check whether there is dirt on both ends of the electronic laparoscope. Wipe the lenses at both ends with a cotton swab dipped in alcohol before observing.
Check the light guide cable and camera cable: After the operation, the camera and light guide cable need to be checked at the bedside to confirm whether the camera has any failure during use, such as missing images or lack of color. Observe whether the camera cable is twisted or the outer skin is damaged.
Check the monitor and cold light source system: Display camera system failure may include black screen phenomenon, which may be caused by the fall-off of the monitor, cold light source system power connector, camera cable connector, poor contact and damage of the cold light source system bulb, etc. Therefore, the equipment should be carefully inspected before surgery, and the replacement of the cold light source system should be prepared.
In order to reduce the failure rate of laparoscopic equipment, regular maintenance and care are essential. Here are some detailed steps and measures:
Establish standard operating procedures: First, a set of standard and standardized operating procedures needs to be formulated, including specific operating methods for each link such as cleaning, disinfection, and sterilization. These procedures should specify the time, temperature, concentration and other parameters of each step to ensure the cleaning and disinfection effect of the instrument.
Daily cleaning and disinfection: The removable parts of the laparoscopic equipment should be disassembled and cleaned immediately after surgery. It can be soaked with enzymes first and then rinsed with running water; in addition, the tube core, the front section of the outer tube and other parts of the instrument should be checked for damage during postoperative finishing, and ensure that the parts are tightened when the joints are loose.
Strict management system: Establish a strict laparoscopic instrument management system and strictly implement it. This includes control over the use, transportation, cleaning, packaging, disinfection, sterilization and other links of the instrument. Through link management, the damage rate and failure rate of the instrument can be effectively reduced.
FOCUS-PDCA management method: Apply FOCUS-PDCA management method to sort out each link in the use cycle of hospital laparoscopic instruments, classify the fault types and find out the causes of laparoscopic instrument failure in each link, so as to take targeted improvement measures.
Scientific and reasonable use: Only by understanding the composition of the laparoscopic system and the functions and characteristics of each device can problems be discovered and solved in time. Avoid using violence during operation, handle with care to prevent damage to the instrument.
Regular inspection and maintenance: Regularly inspect and maintain laparoscopic equipment to discover and repair potential problems in time. Focus on checking whether the instrument's core, front section of the outer tube and other components are damaged or broken.
Repair and update: For equipment that has already failed, it should be repaired or replaced in time. Develop targeted maintenance measures and record the time, cause and result of each maintenance for subsequent reference.
