FAQ

1. What is the typical weight capacity of an electric hydraulic operation table?

The typical weight capacity of an electric hydraulic operation table ranges from 300 kg to 500 kg, depending on the model and manufacturer. Bariatric-specific models can support up to 500 kg or more, making them suitable for obese patients. Standard models for general surgery usually handle 250-300 kg. The hydraulic system provides the necessary force to lift these heavy loads smoothly. It is crucial to check the manufacturer’s specifications before use to avoid overloading, which could damage the hydraulic pump or compromise patient safety. Overloading may also void warranties and lead to costly repairs. For pediatric or lightweight patients, lower capacity tables are available, but the electric hydraulic design is preferred for its versatility and robustness in handling diverse surgical needs.

2. How does the electric hydraulic system improve surgical precision?

The electric hydraulic system improves surgical precision by allowing micro-adjustments in table positioning without jarring movements. The hydraulic fluid dampens vibrations, ensuring the table remains stable during delicate procedures like neurosurgery or spinal surgery. Electric controls enable fine-tuning of height, tilt, and rotation in increments as small as 1 mm or 1 degree. This level of control helps surgeons access difficult anatomical areas with minimal patient repositioning. Additionally, the system can be programmed to save specific positions, reducing setup time for repetitive procedures. The combination of electric precision and hydraulic power ensures that the table holds its position securely, even under heavy loads, which is critical for accuracy in orthopedic and cardiac surgeries.

3. What maintenance is required for the hydraulic fluid in these tables?

Hydraulic fluid maintenance is essential for the proper functioning of an electric hydraulic operation table. The fluid should be checked monthly for level and clarity. Low fluid levels can cause sluggish movement or pump cavitation, while cloudy or discolored fluid indicates contamination or degradation. It is recommended to replace the hydraulic fluid annually or every 2,000 hours of operation, whichever comes first. Use only manufacturer-approved hydraulic fluid to avoid damaging seals or valves. During fluid changes, the system should be bled to remove air bubbles that can cause spongy movement. Additionally, hydraulic filters should be replaced at the same interval to prevent debris from circulating. Proper fluid maintenance ensures smooth operation and extends the life of the hydraulic pump and actuators.

4. Can electric hydraulic operation tables be used with MRI or CT scanners?

Yes, many electric hydraulic operation tables are designed to be compatible with MRI and CT scanners, but specific models must be chosen for this purpose. Tables with radiolucent tabletops made from carbon fiber allow X-rays and CT scans to pass through without interference. For MRI compatibility, the table must be made from non-ferromagnetic materials to avoid attraction to the magnetic field. Some tables feature detachable tops that can be transferred directly into the scanner bore, minimizing patient movement. However, the hydraulic and electric components must be shielded or placed outside the MRI room to prevent interference. Always verify the manufacturer’s specifications for imaging compatibility before use, as using incompatible tables can damage equipment or produce poor image quality.

5. What are the common causes of malfunction in electric hydraulic operation tables?

Common causes of malfunction include hydraulic fluid leaks due to worn seals or damaged hoses, electrical faults from loose connections or failed actuators, and control panel issues like unresponsive buttons or display errors. Fluid contamination from moisture or debris can cause pump failure, while overloading the table beyond its capacity can strain the hydraulic system. Battery backups may fail if not regularly tested or replaced. Environmental factors like extreme temperatures or humidity can also affect performance. Preventive maintenance, such as regular inspections and timely repairs, can mitigate these issues. If a malfunction occurs, the emergency manual pump should be used to safely lower the patient, and a certified technician should be called immediately.

6. How much does an electric hydraulic operation table typically cost?

The cost of an electric hydraulic operation table varies widely based on features, brand, and accessories.
