Description

Technical Field

[0001] This invention relates to the field of operating table technology, and more specifically to an electrically operated, retractable operating table. Background Technology

[0002] Most of the components of existing operating tables are detachable, making assembly time-consuming and laborious when complex patient positioning is required. For example, in laparoscopic radical resection of rectal cancer in obese patients, a head-down, feet-up combined lithotomy position is needed. We require shoulder supports to prevent the patient from sliding down, arm supports for arterial puncture, and a lithotomy frame for anal surgery. Positioning the patient takes up most of the time between anesthesia and the start of surgery. Furthermore, current operating tables are only about 50 centimeters wide, and with the increasing number of obese patients who can barely fit on the table, there is often insufficient space for proper upper limb positioning. Wider tables are needed to ensure patient safety. Existing operating tables cannot be rotated left-right or forward-backward. If the patient's surgical position is on one side, the current operating table is inconvenient to use.

[0003] Therefore, existing operating tables, due to their limited functionality and inability to be adjusted to suit different patients' conditions, cannot be used to meet the needs of patients with different illnesses. Summary of the Invention

[0015] The beneficial effects of this invention are:

[0016] (1) First, turn on the first motor, which drives the first threaded rod to rotate; then turn on the fifth electronic telescopic rod, so that the sixth slider moves down and meshes with the first threaded rod, and then the first threaded rod drives the sixth slider and the second rack to move, and then the ninth gear rotates and drives the first rack to move, and then the second bed board moves, so that the length of the second bed board can be adjusted, and thus it can be adapted to people of different heights. When the lithotomy patient uses it, the second bed board can be retracted, which makes it easier for the patient to use and easier for the doctor to perform surgery. After adjustment, the second bed board is automatically locked in the first slot through the first spring telescopic rod and the first roller, and then the fifth electronic telescopic rod is reset, and then the sixth slider is reset. Thus, the adjustment of the bed board adjustment component is completed. The structure is simple and convenient, easy to operate, and will not affect the adjustment of other positions.

[0017] (2) When foot support is required, the sixth electronic telescopic rod is opened, causing the seventh slider to move upward, which in turn causes the tenth gear to mesh with the first threaded rod. The first threaded rod then drives the tenth gear to rotate, which in turn drives the third rack, connecting rod, connecting plate, first foot baffle, and second foot baffle to move up and down, thus providing foot support. After adjustment, the first foot baffle is automatically locked in the second slot by the second spring telescopic rod and the second roller, thus automatically limiting the first and second foot baffles after adjustment. Then, the sixth electronic telescopic rod is reset, and the ninth gear is reset. This completes the adjustment of the foot baffle assembly. The structure is simple and convenient, easy to operate, and does not affect the adjustment of other positions.

[0018] (3) When it is necessary to flip the operating table, turn on the second motor, which drives the support frame, the first bed board and the second bed board to rotate and flip around the second threaded rod; turn on the third motor, which drives the second threaded rod to rotate, which in turn drives the first gear to rotate, so that the first support plate, the second support plate, the first bed board and the second bed board can be flipped around the fixed axis, so that the first bed board and the second bed board can be flipped in different directions, which makes it easier for doctors to perform lateral surgery.

[0019] (4) Since patients have different neck lengths and shoulder distances, the existing shoulder support positions are fixed and therefore cannot be adapted to different patients. Therefore, when it is necessary to adjust the shoulder distance, the first electronic telescopic rod is opened, so that the first slider moves down and engages with the first threaded rod. The first threaded rod drives the first slider to move, which in turn drives the first slide bar to move in the first slide groove, thereby adjusting the distance between the shoulder support and the pillow. Then, the second electronic telescopic rod is opened, so that the second slider moves down and engages with the third threaded rod, which then drives the third threaded rod to rotate, thereby moving the first moving block and the second moving block, thereby adjusting the distance between the first shoulder support and the second shoulder support. The structure is simple and easy to operate, providing great convenience for doctors and making patients more comfortable.

[0020] (5) When it is necessary to widen or retract the bed, open the third electronic telescopic rod to move the third slider, so that the third gear meshes with the first threaded rod, and the fourth gear meshes with the fifth gear and the seventh gear meshes with the eighth gear. Then the first threaded rod drives the third gear to rotate, which in turn causes the second gear and the fourth gear to rotate, the sixth gear and the seventh gear to also rotate, which in turn causes the fifth gear to rotate and drive the first plate to rotate, and the eighth gear to rotate and drive the second plate to rotate, thus widening or retracting the bed.

[0021] (6) The first arm support plate and the second arm support plate can be hidden or removed by the hidden components, which makes it easy to store and manage.

[0022] (7) Through this invention, each position can be adjusted individually, which is simple and convenient, easy for doctors to operate and perform surgery, and also brings comfort to patients. In addition, when all positions are adjusted, all positions can be matched with the first threaded rod, and then the first motor can be turned off, so that the first motor and the threaded rod stop rotating, thereby locking the adjusted positions again to prevent accidental movement or rotation.

[0052] Specifically, the foot baffle assembly 12 includes a first movable groove 121 disposed on the second L-shaped plate, a first foot baffle 122 movably disposed on the first movable groove, a second movable groove 123 disposed on the second L-shaped plate, a second foot baffle 124 movably disposed on the second movable groove, a connecting plate 125 fixed at one end on the first foot baffle and the other end fixed on the second foot baffle, a seventh slider 126 slidably disposed on the second L-shaped plate, and a tenth tooth rotatably disposed on the seventh slider and meshing with the first threaded rod. Wheel 127, fifth base plate 128 fixedly mounted on the second bed board, sixth electronic telescopic rod 129 fixed at one end on the fifth base plate and at the other end on the seventh slider, third rack 1210 movably mounted on the second bed board and meshing with the tenth gear, connecting rod 1211 fixed at one end on the first foot baffle and at the other end on the third rack, second spring telescopic rod mounted on the first foot baffle, second roller rotatably mounted on the second spring telescopic rod, and multiple second slots mounted on the first bed board.

[0053] Specifically, the hidden component 13 includes a sliding cavity disposed within the first bed board, a first block 131 fixedly disposed on the first arm support plate, a second block fixedly disposed on the second arm support plate, a fourth threaded rod 132 rotatably disposed on the first block with one end passing through and rotatably disposed on the second block with the other end passing through and rotatably disposed on the second block, a first transmission wheel slidably sleeved on the fourth threaded rod, a rodless cylinder 133 disposed on the first bed board, a shaft disposed on the rodless cylinder, a second transmission wheel sleeved on the shaft, a transmission belt 134 wound around the first transmission wheel with one end passing through and the second transmission wheel with the other end passing through, and a fourth transmission wheel 135 fixedly disposed on the shaft; the two ends of the fourth threaded rod are threaded, and the thread directions of the two ends are opposite.

[0054] In use, this invention first activates the first motor, which drives the first threaded rod to rotate. Then, the fifth electronic telescopic rod is activated, causing the sixth slider to move downwards and engage with the first threaded rod. This, in turn, causes the first threaded rod to move the sixth slider and the second rack, which in turn rotates the ninth gear and moves the first rack, thus moving the second bed board. This allows for adjustment of the second bed board's length to accommodate people of different heights. Furthermore, when used by a lithotomy patient, the second bed board can be retracted for easier use by the patient and for the surgeon. After adjustment, the second bed board automatically engages in the first slot via the first spring telescopic rod and the first roller. Then, the fifth electronic telescopic rod is reset, and the sixth slider is reset. This completes the adjustment of the bed board assembly. The structure is simple and convenient, easy to operate, and does not affect the adjustment of other positions.

[0055] When foot support is needed, opening the sixth electronic telescopic rod causes the seventh slider to move upward, which in turn engages the tenth gear with the first threaded rod. The first threaded rod then drives the tenth gear to rotate, which in turn moves the third rack, connecting rod, connecting plate, first foot plate, and second foot plate up and down, thus providing foot support. After adjustment, the first foot plate automatically engages in the second slot via the second spring telescopic rod and the second roller, automatically limiting the position of the first and second foot plates after adjustment. Then, the sixth electronic telescopic rod is reset, and the ninth gear is reset. This completes the adjustment of the foot plate assembly. The structure is simple and convenient, easy to operate, and does not affect the adjustment of other positions.

[0056] When the operating table needs to be flipped, the second motor is turned on, which drives the support frame, the first bed board, and the second bed board to rotate and flip around the second threaded rod. The third motor is turned on, which drives the second threaded rod to rotate, which in turn drives the first gear to rotate, thereby causing the first support plate, the second support plate, the first bed board, and the second bed board to flip around the fixed axis. This allows the first bed board and the second bed board to be flipped in different directions, making it easier for doctors to perform lateral surgery.

[0057] Because patients have different neck lengths and shoulder distances, the existing shoulder support positions are fixed and therefore cannot be adapted to different patients. Therefore, when shoulder distance adjustment is needed, the first electronic telescopic rod is activated, causing the first slider to move downwards and engage with the first threaded rod. The first threaded rod drives the first slider to move, which in turn moves the first sliding rod within the first groove, thus adjusting the distance between the shoulder support and the pillow. Then, the second electronic telescopic rod is activated, causing the second slider to move downwards and engage with the third threaded rod. This drives the third threaded rod to rotate, causing the first and second moving blocks to move, thus adjusting the distance between the first and second shoulder supports. The structure is simple and easy to operate, providing great convenience for doctors and making patients more comfortable.

[0058] When it is necessary to widen or retract the bed, the third electronic telescopic rod is opened, causing the third slider to move. This causes the third gear to mesh with the first threaded rod, and the fourth gear to mesh with the fifth gear, and the seventh gear to mesh with the eighth gear. The first threaded rod then drives the third gear to rotate, which in turn causes the second and fourth gears to rotate, as well as the sixth and seventh gears. This causes the fifth gear to rotate and drive the first plate to rotate, and the eighth gear to rotate and drive the second plate to rotate, thus widening or retracting the bed.

[0059] Initially, the first and second arm support plates are hidden. When needed, a rodless cylinder is driven, which moves the shaft, second transmission wheel, and fourth transmission wheel. Simultaneously, the first transmission wheel and conveyor belt move. When the fourth transmission wheel engages with the first threaded rod, the first threaded rod rotates, causing the fourth transmission wheel to rotate, which in turn rotates the shaft and second transmission wheel, which in turn rotates the conveyor belt. This causes the first transmission wheel and the fourth threaded rod to rotate. Since the threads at both ends of the fourth threaded rod are set in opposite directions, the first and second blocks move in opposite directions, allowing the first and second arm support plates to be moved out for easy use.

[0060] This invention allows for individual adjustment of each position, which is simple and convenient, facilitating doctor's operation and surgery, while also providing comfort to the patient. Furthermore, when all positions are adjusted, they can be engaged with the first threaded rod, and then the first motor can be turned off, causing the first motor and the threaded rod to stop rotating. This allows the adjusted positions to be locked again, preventing accidental movement or rotation.

[0061] During surgery, the drive motor rotates the second partition plate to one side, simultaneously driving the rodless cylinder to move the sliding block and the second partition plate to one side, thus making way. During this movement, the connecting plate drives the first threaded rod to rotate. The first threaded rod rotates through a universal joint, which maintains the transmission of the first threaded rod. At the same time, the second L-shaped plate rotates through a movable rod, which maintains the connection between the first and second connecting plates. This allows the surgeon to stand on one side of the operating table for more convenient surgery.

[0062] The rodless cylinder is existing technology.
