Edit the technical requirements of this paragraph.

Most electric operating tables use hydraulic cylinders or gas spring cylinders. The Y-shaped bed seat is adopted to ensure the highest stability and the largest free space of the operating bed, so that medical staff can get close to patients at zero distance. The operating table should have strong mobility, four-wheel landing design, convenient movement, and a central mechanical braking device, and the casters are locked or released through the center of the pedal rod. Its bearings are sealed and waterproof, easy to clean, and the water, blood and suture in the operation will never be entangled in the bearings. Gently press the head handle to achieve head and foot tilt and left-right tilt. Both the leg plate and the back plate joints are provided with gas spring cylinder support structures, which make all adjustments soft, silent and vibration-free, and at the same time effectively protect the joint structure and prevent patients from falling. According to the individual characteristics of China people, China's medical device industry standard stipulates that the length of the operating table is 2 m and the width is 0.48 m, and the anteroposterior inclination of the whole operating table is not less than 25, the left-right inclination is not less than 20, the folding angle of the head plate is not less than 30, the folding angle of the back plate is not less than 45, the folding angle of the back plate is not less than 80, the folding angle of the back plate and the seat plate is not more than 90, and the folding angle is not more than 65438. At the same time, the industry standard also requires that the operating table products should adopt the structure of double legs as far as possible, and the double legs can rotate both sides in the same plane. After rotation, the included angle between the inner sides of the legs should not be less than 180 table top, and all adjustments are stepless.

Current situation of use

Comparison between electric operating table and other operating tables Operating table is one of the basic medical instruments for surgical treatment, which can be divided into portable operating table, manual hydraulic driving operating table and electric operating table. Portable operating table is generally made of thin steel plate, section steel or other materials, mainly composed of bedstead and bed surface. Simple and lightweight structure, suitable for general diagnosis and treatment, examination and other surgical operations, can be folded or disassembled when not in use, is convenient for loading and transportation, and can be deployed in simple operating rooms, tents, operating cabins and private houses; It is also suitable for other special occasions, such as portable medical multifunctional diagnosis and treatment bed for field and field treatment. Compared with the traditional operating bed, it is mainly characterized by folding, small size, light weight and easy to carry.

Manual hydraulic transmission operating table uses air cylinder as actuator to control the movement of table top. Its main working process is: when the valve of the cylinder is opened, the upper and lower cavities of the cylinder are communicated, and the piston can be adjusted to the required position at this time; After the cylinder valve is closed, the upper and lower cavities of the cylinder are separated, because the gas pressure in the cylinder can keep the piston position unchanged. Because the electric operating table adopts electro-hydraulic transmission mechanism, it is convenient for the operator to adjust directly under the control of wired remote controller or infrared remote controller and foot control panel. It can also be matched with Figure 2, which is suitable for central locking or unlocking at different positions of the electric operating table. Its bearings are sealed and waterproof, easy to clean, and the water, blood and suture in the operation will never be entangled in the bearings. Gently press the head handle to achieve head and foot tilt and left-right tilt. Both the leg plate and the back plate joints are provided with gas spring cylinder support structures, which make all adjustments soft, silent and vibration-free, and at the same time effectively protect the joint structure and prevent patients from falling. According to the individual characteristics of China people, China's medical device industry standard stipulates that the length of the operation is 2m, the width is 0.48m, the whole table is tilted not less than 25 before and after, not less than 20 from left to right, not less than 30 from the head plate, not less than 45 from the bottom plate, not less than 80 from the back plate, not more than 90 from the back plate to the seat plate and not more than 65438 from the bottom plate. At the same time, the industry standard also requires that the operating table products should adopt the structure of double legs as far as possible, and the double legs can rotate both sides in the same plane. After rotation, the included angle between the inner sides of the legs should not be less than 180 table top, and all adjustments are stepless.
