Operating table is basic medical equipment for surgery, it can be divided into 3 kinds: light operating table, manual hydraulic operating table and electric operating table. Light operating table generally is made of sheet steel or other materials, mainly consists of 2 parts: table frame and table board. Its structure is simple and light, suitable for general medical treatment, examination and other surgical operations. Can be folded or disassembled when not in use, easy to load and transport. It can be deployed in simple operating rooms, tents, surgical shelters, and houses, as well as other special occasions, such as portable medical multi-purpose beds for field and field treatment. Compared with traditional operating table, its main features are foldable, small in size, light in weight, and easy to carry. The manual hydraulic operating table uses the cylinder as an actuator to control various actions. Its main working process is: When the cylinder valve is opened, the upper and lower chambers of the cylinder communicate, and the piston can be adjusted to the desired position at this time; After closing the cylinder valve, the upper and lower chambers of the cylinder are separated. At this time, the position of the piston can be maintained due to the gas pressure in the cylinder. The electric operating table uses electro transmission. Wired remote or infrared remote control, with the foot control panel, easy to adjust patients` position, magnetic calve can be equipped.
