FAQ
The failure rates and common failures of micro-laparoscopic surgical instruments are as follows:
Failure rate
According to foreign research, the detection rate of laparoscope insulation failure instruments is 37.0%, and the visual failure rate is 22.3%. This shows that in actual use, laparoscopic surgical instruments have a certain failure rate and need to be regularly inspected and maintained.
Common failures
Display camera system failure
Black screen phenomenon: The display, cold light source system power connector, camera cable connector fall off, poor contact and damage of the cold light source system bulb, etc. will cause the display to black screen.
Unclear image: The camera focal length is too high or the lens is contaminated with foreign matter, which can cause unclear images. Fine-tuning the focal length or wiping the lens with an iodine cotton swab can solve such problems.
Image brightness imbalance: Too bright or too dark light in the operating room will affect the image quality. When it is too bright, the shadowless lamp should be turned off and the cold light source should be adjusted to the automatic position; when it is too dark, the lighting fiber may need to be replaced.
Insufflator failure
Insufflator needle blockage: During the operation, the insufflator needle may be blocked by fat particles, blood clots or other tissue fragments. The treatment measure is to use a 5 ml syringe to draw saline to flush it.
Insufflator pressure is too low: air leakage caused by loose joints of the gas pipeline and damage to the sealing cap of the puncture device. Incorrect setting of CO2 pressure parameters will also cause the insufflator pressure to be too low.
High-frequency electrosurgical knife failure
High-frequency electrosurgical knife does not work: After connecting the negative board and connecting the wires, the negative plate alarms and the high-frequency electrosurgical knife does not work.
Other common faults
Monitor image is deeply distorted: During the operation, the monitor image is deeply distorted. The replacement method is used for inspection and repair. It is found that the monitor setting parameters or the monitor itself are likely to be damaged.
Electromagnetic interference: Interference occurs when using an electrosurgical knife, which is generally electromagnetic interference. Increase the distance between the electrosurgical knife and the ultrasound knife to avoid plugging their power cords into the same socket.
These faults will not only affect the smooth progress of the operation, but may also lead to the failure of the operation. Therefore, daily maintenance and regular inspection of surgical instruments are essential.
The specific causes of insulation failure of micro-laparoscopic surgical instruments mainly include the following points:
Damage of the insulation layer of the electrosurgical knife: In laparoscopic surgery, the insulation layer damage of the electrosurgical knife and the capacitive coupling of the sleeve are one of the common causes of accidental injury.
Changes in sterilization methods: Some laparoscopic instruments were originally sterilized by glutaraldehyde immersion, and then changed to low-temperature plasma or ethylene oxide sterilization, resulting in deformation or shedding of the outer insulation layer of the instrument.
Preventive measures include:
Regular insulation performance testing: Regular insulation performance testing of laparoscopic surgical instruments by visual inspection and instrument detection methods to promptly detect and deal with insulation layer damage.
Maintain a consistent sterilization method: Try to avoid frequent changes in sterilization methods to prevent deformation or shedding of the insulation layer due to changes in sterilization methods.
Formulate routine insulation performance testing quality control specifications: Establish and improve quality control specifications for insulation performance testing to ensure that each instrument undergoes strict testing before use.
To effectively reduce the incidence of display camera system failures in micro-laparoscopic surgery, the following measures can be taken:
Daily maintenance and care: Regularly check and maintain the camera system to ensure its normal operation. For example, avoid frequent plugging and unplugging of the camera, connect it to the host when not in use, and perform maintenance at least once a week.
Prevent external interference: During the operation, pay attention to avoid interference from external high-frequency equipment to ensure that the shielding function and information transmission function of the camera system are normal.
Correct operation and use: Clinical surgical staff should use the equipment in strict accordance with the operating procedures to avoid inadvertently adjusting the white balance of the camera to cause color distortion and other problems.
Scientific and standardized management: Establish a scientific and standardized equipment management and maintenance system to ensure that the equipment operates in the best condition.
Timely repair and replacement: Once a camera system failure is found, such as abnormal phenomena such as interference ripples and color stripes, the relevant parts should be repaired or replaced in time.
In micro-laparoscopic surgery, there are several treatment techniques and prevention methods for insufflator blockage:
Instantaneous smoke removal and hierarchical filtration: The micro-intelligent insufflator system has instantaneous smoke removal function and hierarchical filtration system. The instantaneous smoke removal function can always keep the surgical field clear, improve the smoothness of the operation, and shorten the operation time; the hierarchical filtration system can effectively filter particles to ensure the safety of the surgical environment.
Stable insufflator and high-flow gas supplementation: Accurately control abdominal pressure through original algorithms to ensure surgical safety.
Emergency treatment method: When the insufflator fails during surgery, the sphygmomanometer air bag and CO2 air bag can be connected between the flow meter to replace the insufflator. This method has a simple structure, easy operation, low cost, and is suitable for emergency situations.
Regular maintenance and cleaning: Regularly clean the inside of the gas circuit module and replace parts to prevent insufflator failure. The maintenance cycle is 4 working days and the warranty period is 6 months.
Safe operation and complication prevention: During the gas injection process, the gas injection should be started at a flow rate of 1-2 L/min to give the body a process to adapt to the changes in intra-abdominal pressure. If the patient's blood pressure and heart rate are stable, the flow rate can be gradually increased. In addition, when establishing pneumoperitoneum, the position of the pneumoperitoneum needle should be verified again through an inflation test, and the intra-abdominal pressure should not exceed 1.3KPa (10mmHg) during the initial gas injection, and gradually increase with the increase of gas injection volume.
Correct connection and inspection: Connect the pneumoperitoneum machine to the CO2 cylinder, open the CO2 cylinder valve, and check for leaks. Connect the power supply, turn on the power switch, and detect the pressure of the CO2 cylinder. After adjusting various parameters, press the gas injection button to eliminate the residual gas in the host, and then turn off the gas injection button to empty the accumulated gas consumption for standby.
The common reasons and solutions for high-frequency electrosurgical unit failure are as follows:
Power supply problem:
The main power supply is not sent to the machine: it may be that there is no AC220V voltage in the external power socket, or the power cord is poorly connected or damaged.
Power failure: Check whether the power supply and wires are in good contact, ensure that the power supply is in good contact, and check whether the power cord is firmly connected and not disconnected or damaged.
Electrosurgical knife control circuit failure:
Function setting error: When using a high-frequency electrosurgical knife, if there is no power output for electrocuting and electrocoagulation after the foot switch is pressed, it may be a function setting error.
Control circuit failure: Check whether the electrosurgical knife control circuit is faulty, which may require professional maintenance personnel to repair.
Foot switch failure:
Foot switch problem: If there is a problem with the foot switch, the electrosurgical knife will not work properly. It is necessary to check whether the function of the foot switch is normal.
Negative plate problem:
Negative plate wire is damaged or short-circuited: Check whether the appearance of the negative plate wire is damaged, check whether there is any negative plate residue inside the plate clamp, and then check whether there is a break or short circuit inside.
Power setting is too high:
Cutting is accompanied by sparks: It may be that the power setting is too high. Refer to the adjustment table in the electrode box and set the power level according to the cutting situation and the selected electrode.
Other common faults:
Instrument self-test failure: After the instrument self-tests for a few seconds after power on, the power protection and power switch are automatically turned off. It may be an internal circuit problem.
Negative plate alarm abnormality: The negative plate indicator light cannot turn green, which may be a problem with the negative plate and its wires.
Micro-laparoscopic surgical instruments may be subject to electromagnetic interference (EMI) during use, affecting the smooth progress of the operation. In order to identify and reduce this interference, the following methods can be taken:
Reasonable wiring: Reduce electromagnetic interference through reasonable wiring. Reasonably arrange cables and signal lines, minimize sharing of wiring with high-power power lines or other interference sources, and reduce interference from signal lines.
Shielding measures: Use electromagnetic shielding technology to reduce interference energy by using the shielding body to absorb and reflect interfering electromagnetic waves. This usually uses low-resistance conductor materials and uses electromagnetic waves to generate reflections on the surface of the shielded conductor.
Use decoupling capacitors and bypass capacitors: Filtering can be used on both power lines and signal lines to reduce EMI, including the use of decoupling capacitors, EMI filters, and magnetic components.
Provide a low-impedance return path: Provide a low-impedance, continuous return path under all signals, especially when wiring on the surface layer, to reduce ground bounce.
Choose the right micro-instrument: When performing micro-incision single-port surgery, use a 3 mm micro-lens and a 3 mm needle holder and operating forceps to free up the corresponding operating space and reduce mutual interference between operations.
Double-layer shielding protection system: Use a professional Class A double-layer shielding protection system to solve the electromagnetic interference of the energy platform during surgery (such as interference of ultrasonic scalpels, plasma scalpels, high-frequency electric scalpels and other equipment on video images).
