Electro-hydraulic operation tables, often referred to as surgical or operating tables, are advanced pieces of medical equipment used in modern operating rooms. They provide a stable and adjustable platform for positioning patients during various surgical procedures. Unlike their manual or purely electric counterparts, these tables combine the power of an electric motor with the smooth, controlled movement of a hydraulic system. This hybrid design offers the best of both worlds: the effortless adjustability of electric controls and the robust, precise lifting and tilting capabilities of hydraulics.
The basic function of an electro-hydraulic operation table is to safely and securely position a patient in the optimal orientation for a specific surgical procedure. This can involve a wide range of movements, including raising, lowering, tilting from side to side, and adjusting the trendelenburg and reverse-trendelenburg positions. These adjustments are crucial for providing surgeons with clear access to the surgical site, improving visibility, and enhancing procedural efficiency and safety.
The key components of an electro-hydraulic operation table work in harmony to achieve this functionality. The hydraulic system is the core of the table's power. It consists of a reservoir of hydraulic fluid, a pump, and a series of cylinders that translate the fluid pressure into mechanical motion. The electric controls are the brain of the system, comprising a motor, control unit, and various user interfaces like a handheld remote or a foot pedal. These controls allow the surgical staff to precisely and effortlessly manipulate the hydraulic system. The tabletop is the surface where the patient lies. It is often made from a radiolucent material, allowing for clear X-ray and fluoroscopic imaging during surgery without the need to move the patient. Finally, the base provides stability and mobility, typically featuring heavy-duty castors for easy transport and a braking system to lock the table securely in place during a procedure. Together, these components create a sophisticated, reliable, and essential tool for modern surgical practice.
Electro-hydraulic operation tables represent a significant advancement over traditional manual or purely electric surgical tables, offering a suite of benefits that enhance surgical outcomes, patient safety, and operational efficiency.
