Structural Principle

1. The table utilizes pneumatic spring as working element to control the movement of the table-board. When the cylinder valve is opened, the top part of the cylinder and the bottom part of the cylinder are connected, and then the piston position can be adjusted. When the piston is adjusted to the position as required, close the cylinder valve, and separate the two parts of the cylinder, then, owe to the air pressure in the cylinder, the position of the piston is fixed.

2. Both the ascending and descending movements of the table top are controlled by the oil pump.

Using Method

1. The ascending and descending movements of the table top . (refer to fig. 2)

Elevation of the oil pump is controlled by a long pedal. Press once , table top will rise up a certain Height. Table top will descend when the short pedal is pressed to the dead end and not loosen. Descending speed varies with the pressing force.


2. Head Rest(refer to fig. 3)

The up-down folding of the head rest is controlled by the pneumatic spring. It can be adjusted at any position within the adjustable scope and be disassembled. The head rest can be folded down by pulling the spanner while rotating the head rest to the expected position with the other hand. Leaving the spanner, the head rest will be fixed. If we fold up the head rest, we just pulling the spanner, the head rest will fold up automatically under the effect of the cylinder. Leaving the spanner, the head rest will be fixed. Otherwise, the head rest can be removed by way of rotating off the two fixed buttons, which connect the head rest and back section. The fixed buttons should be assured of being tensed in case of coming off while operating.

3. Back section(refer to fig. 4)

The up-down folding of the back section is controlled by the pneumatic spring. It can be adjusting at any position within the adjustable scope. If the back section is asked to folded up, we should rock the Kidney Bridge to the lowest position, then pulling the spanner of the back section. When the back section automatically folds up to the desired position, leaving the handle, the back section will be fixed. If we fold down the back section, we should hold the handle of back section while the other hand grasps the handle and rock it down to the desired position.

4. Reversed Trendelenburg and Trendelenburg of the table-top(refer to picture 5)

It is controlled by the pneumatic spring. The fore and aft inclination of the table surface is fulfilled by holding the left and right handles at the same time, and lift the fore and aft inclination handle under the right handle with the right fingers. Rotating the table surface up causes the fore inclination while rotating it down causes aft inclination. The surface can be fixed at the specific position while stopping the rotting at desired position.


5. The left and right inclination of the table-top(refer to fig. 6)

It is controlled by the pneumatic spring. Holding the left and right handles at the same time completes the left and right inclination of the table surface. Rotating the table surface left causes the left inclination. Leaving the spanners at the desired position the table surface can be fixed.


6. Leg section(refer to fig. 7)

The down folding of leg section is controlled by the pneumatic spring, which can be adjusted at any position within the adjustable scope, and can be disassembled. Pulling the spanner of leg section while the other hand rotating the leg section down. Leaving the spanner at the desired position, the leg section will be fixed. Pulling the spanner of the leg panel can complete the resetting of the leg panel. Holding the leg panel with the other hand, then the leg section returns under the effect of the cylinder. Unbundling the two fixed buttons can remove the leg section. Make sure the buttons are fixed while assembling the leg section.

7. The locking and moving of the pedestal(refer to fig. 8)

Stepping on the fore-aft pedal of the pedestal can complete the move of the operating table. Stepping on the right pedal can fulfill the locking of the operating table.


8. Kidney Bridge(refer to picture 9)

The up-down position of the kidney bridge can be adjusted by rotating the handle of the kidney bridge. It can be done in both sides of the table. Rotating the handle clockwise while operating on right side, the leg panel descends. Rotating the handle counter clockwise operating on the right side, the panel ascends.

9. Accessories

a. Slider

The operating table adopts single groove slider I, II, to fix all kinds of accessories. Narcosis-frame and leg-rest rack are fixed by inserting into slider I. Body-supporting frame is fixed by inserting into the slider II..

b. Cassette

Except the kidney bridge of the table, the X-ray could go through the other table-board, and take photos of patients. It can take photos when the cassette is put on the shelf under the table. The drag hook of the cassette can adjust the cassette’s position. When putting it on the shelf, you should first take away the thumb wheel of the cephalic plate. After taking photos and taking out the cassette, in order to avoid the slipping down of the cephalic plate while operating, you should screw the thumb wheel of the cephalic plate at once.

C. Arm Supporter

The arm supporter is designed to be fixed on both sides of the operating table. If the position of the panel is designed to adjust, the butterfly-shaped nut should be loosen first. Rotating it to the position then tight the nut. The use of binding requires the unbound of the button and bound the arm of the patient on the panel.

d. Knee Crutch

Penetrating the single groove block Ⅰ into the track, and then inserting the pole of the knee crutch into the hole on the block and fix the handle of the slider. The position of the knee

crutch can be adjusted by loosing the handle under the supporter, which makes the supporter turns any direction. When the panel reaches to the designed position, the handle should be fixed. Pulling the handles of the slider outside completes the moving and revolving of the panel, which causes the separation of the two plane gears. Then turn the rack to the designed position, and combine the two gears and fixing the handle. The position will be done.

e. Body Supporter

Penetrating the single groove block Ⅱ into the track, and inserting the supporter into the channel of slider. It can be fixed by tensing the handle of the slider. The adjustment of the rack is working by loosing the handle which makes the supporter turn up-down and left-right. Getting the designed position, the handle should be tensed. Loosing the button and lifting the supporter fulfill the rotating of the whole. When the connecting-bar and the inserting-bar are separated with the two plane gears, the supporter can revolve on the horizon position. When the revolving reaches the designed position, the button should be fixed to determine the position.

f. Anesthetic Screen

First, penetrating the single groove block Ⅰ into the track, then, inserting the two long bayonets of the anesthetic screen into the two holes of the block and fixing them by screwing the handle. Moreover, loosing two buttons on screen and expanding or moving the two short bayonets up and down can extend the screen’s height and width. If you want to move or turn the screen, loose block handle and pull it outside. After separating the two gears, turn the screen to the required position, and then screw the two gears, and now the screen is fixed on the position.
