Description

Technical Field

[0001] The present invention belongs to the technical field of operating tables, and in particular relates to an electrically adjustable operating table. Background Art

[0002] Electric operating tables are widely used in various surgical procedures, such as general surgery, orthopedics, neurosurgery, urology, and obstetrics and gynecology. During surgery, they provide patients with a comfortable and safe position, while also creating good operating conditions for medical staff and improving surgical efficiency and quality. They are an indispensable and important piece of equipment in modern operating rooms.

[0003] During posterior thoracic and lumbar spine surgery, the patient needs to lie prone on the operating table, and the chest is raised to allow the thoracolumbar spine to stretch better. At the same time, the patient's legs need to be bent while lying prone, which helps the surgeon see the structural details of the spine more clearly. Existing operating tables generally have four corresponding chest lifters installed on the bed board, and also use external support pads to support the patient's legs. However, this structure of the operating table will cause certain effects when performing other surgeries, making it inconvenient to use for other surgeries. The chest lifter and support pads need to be removed, which is inconvenient to use, and the operating table has certain usage limitations. Summary of the Invention

DETAILED DESCRIPTION

[0029] The following is combined with Figures 1-11 The present invention is described in further detail.

[0030] Please refer to Figure 1 、 Figure 2 and Figure 5 An electrically adjustable operating bed comprises a hydraulic lifting device 2 fixed to the ground via a base 1, the output shaft of the hydraulic lifting device 2 being connected to a main bed board 3, the rear side of the main bed board 3 being connected to a tail bed board 5 via a connecting mechanism 1 4, the connecting mechanism 1 4 comprising a connecting plate 1 41 fixedly arranged on the rear lower end surface of the main bed board 3 and having an L-shaped structure, a guide seat 42 being fixedly arranged on the connecting plate 1 41, a through hole 1 penetrating the lower side of the guide seat 42 being opened on the upper side thereof, a connecting plate 1 being slidably arranged in the through hole 1 Column 43, the upper side of the connecting column 43 is rotatably connected to the lower end surface of the tail bed board 5, and a through hole 2 is commonly opened between the left and right sides of the horizontal section of the connecting plate 1 41 and the left and right sides of the guide seat 42, and a limit plate 44 is movably inserted in the through hole 2, and the horizontal section of the connecting plate 1 41 is threadedly connected with two left and right symmetrical locking bolts 1 45, and the lower end of the locking bolt 1 45 movably passes through the limit plate 44, and a through hole 3 is opened on the left side of the connecting column 43 near the lower side, which passes through its right side, and the through hole 3 is adapted to the limit plate 44.

[0031] See Figure 1 、 Figure 2 、 Figure 5 and Figure 11 , a connecting plate 2 46 located on the upper side of the horizontal section of the connecting plate 1 41 is fixedly connected to the guide seat 42, and a through hole 4 extending along the length direction is provided between the upper and lower sides of the connecting plate 2 46, and a connecting plate 3 47 is hinged on the lower side of the tail bed board 5. The connecting plate 3 47 is movably arranged in the through hole 4, and the left and right sides of the connecting plate 2 46 are provided with a through hole 5 extending along the length direction, and the through hole 5 is connected to the through hole 4, and a locking rod 48 is commonly provided between the two through holes 5, and a plurality of through holes 6 distributed along the length direction are commonly provided between the left and right sides of the connecting plate 3 47, and the locking rod 48 movably passes through the corresponding through hole 6, and baffles are provided at both ends of the locking rod 48, any one of the baffles is fixedly connected to the locking rod 48, and the other baffle is threadedly connected to the locking rod 48.

[0032] During specific operation, under normal circumstances, the tail bed board 5 is placed horizontally with the main bed board 3. The baffle on the locking rod 48 can be rotated and the locking rod 48 can be pulled out from the through hole five to release the limit on the connecting plate three 47. The tail bed board 5 can be pushed upward from the rear side of the tail bed board 5 so that the tail bed board 5 rotates to a certain angle. At this time, the locking rod 48 is inserted into the through hole five again and passes through the through hole on the connecting plate three 47 to limit the connecting plate three 47 again, so that the tail bed board 5 remains in a tilted state, which is convenient for adapting to the body position requirements during some operations.

[0033] During some special surgeries, such as posterior thoracic and lumbar spine surgeries, the patient needs to support his legs after lying down. At this time, the locking rod 48 is first removed, and then the locking bolt 1 45 is rotated to pull the limit plate 44 out of the second through hole, so that the connecting column 43 can slide relative to the guide seat 42. At this time, the tail bed board 5 is raised to a certain height, and then the connecting column 43 is pulled out and the tail bed board 5 is horizontally rotated 180 degrees so that the tail bed board 5 overlaps with the rear half of the main bed board 3 (as shown in FIG. Figure 11 As shown), at this time, the connecting plate 2 46, the connecting plate 3 47, and the locking rod 48 are located in the corresponding receiving grooves opened on the main bed board 3, and then the connecting column 43 is inserted into the guide seat 42, so that the through hole 3 on the connecting column 43 is in the guide seat 42, and the limit plate 44 is inserted into the through hole 3 and then locked by the locking bolt 1 45, so that the back half of the main bed board 3 is raised. After the patient lies down, his feet are placed on the tail bed board 5 at this time, and the knees are placed on the main bed board 3, so that the patient's legs form an inclined position. When the legs are slightly tilted, especially when the knee and hip joints are properly bent, the tension of the patient's leg muscles can be reduced, making the patient's lying posture more stable and comfortable. This stable posture is conducive to ensuring the accuracy of the operation.

[0034] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 Two left-right symmetrical main beams 6 are provided on the front side of the main bed board 3, a head bed board 7 is slidingly provided on the two main beams 6, and a connecting mechanism 2 8 is provided between the two main beams 6, and four chest lifters 9 are provided on the connecting mechanism 2 8.

[0035] See Figure 1 、 Figure 4 、 Figure 6 and Figure 10 The second connecting mechanism 8 includes two slide rail assemblies 81. Both slide rail assemblies 81 are arranged between the two main beams 6 and are distributed front to back. An adjustment assembly 82 is provided on the slide rail assembly 81. The adjustment assembly 82 is connected to the corresponding two chest lifters 9. A transmission assembly 83 is provided on the right side of the two slide rail assemblies 81. A drive assembly 84 is provided between the slide rail assembly 81 located on the front side and the headrest board 7. The headrest board 7 moves backward along the main beam 6 to control the action of the drive assembly 84. The drive assembly 84 cooperates with the transmission assembly 83 to rotate the two slide rail assemblies 81, thereby controlling the four chest lifters 9 originally located above the main beam 6 to rotate and switch to the bottom of the main beam 6 for hiding.

[0036] See Figure 1 、 Figure 4 、 Figure 8 、 Figure 9 and Figure 10 The left and right sides of both main beams 6 are each provided with a guide rail groove (1) with a stepped cross-section. A guide bar (10) is fixedly mounted on the underside of the headboard 7, symmetrically positioned to fit within the guide rail groove. The guide bar (10) slides within the guide rail groove. Locking bolts (2) are threadedly mounted on the left and right rear portions of the headboard 7. Two symmetrical through holes (7) are defined on the sides of the two main beams 6 facing away from each other. Locking bolts (2) 11 flexibly engage with the corresponding through holes (7). The headboard 7 moves stably forward and backward along the main beams 6 via the guide bar (10), and the locking bolts (2) 11 constrain the headboard 7 between the main beams 6.

[0037] See Figure 4 、 Figure 6 and Figure 7 The slide rail assembly 81 includes two slide seats 811, and the two slide seats 811 are respectively slidably set on the corresponding main beam 6. The two left and right corresponding slide seats 811 are each rotatably set with a rotating shaft 812 on one side close to each other. The two left and right corresponding rotating shafts 812 are fixedly connected to a connecting seat 813 at one end close to each other, and the adjustment assembly 82 is set on the connecting seat 813.

[0038] See Figure 2 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9On the left and right sides of the main beam 6 and below the guide rail groove 1, there are guide rail grooves 2 with a stepped cross-section. A guide bar 2 12 is slidably arranged in the guide rail groove 2, and two adjacent guide bars 2 12 are fixedly connected to the same slide 1 811; the two slides 1 811 located on the front side are threadedly provided with a locking bolt 3 13 on the side away from each other, and the locking bolt 3 13 is movably connected to the side wall of the corresponding main beam 6, and the two slides 1 811 located on the rear side are threadedly provided with a locking bolt 4 14 on the side away from each other, and one end of the locking bolt 4 14 is movably in contact with the side wall of the corresponding main beam 6. It should be noted in particular that during installation, the two slides 811 located on the front side will no longer move after being installed and fixed on the main beam 6 by the locking bolts 3 13. Although the slide 1 811 located on the rear side is fixed on the main beam 6 by the locking bolts 4 14, when necessary, the locking bolts 4 14 can be rotated in the opposite direction so that it is not pressed against the side wall of the corresponding main beam 6, so that the slide 1 811 on the rear side can move stably back and forth along the main beam 6 through the guide bar 2 12 and drive the corresponding connecting seat 813 to move, adjust the distance between the front and rear connecting seats 813, and lock them again by the locking bolts 4 14 after reaching the specified position. At the same time, the connecting seat 813 can also rotate relative to the slide 1 811 through the rotating shaft 1 812, thereby adjusting the distance between the two chest lifters 9 on the rear side and the two chest lifters 9 on the front side.

[0039] See Figure 4 、 Figure 6 and Figure 7 A sliding groove is provided on the upper side of the connecting seat 813, and the adjusting component 82 includes a screw 821 rotatably set in the sliding groove. The screw 821 is provided with two threaded sections with opposite thread directions and the two threaded sections are threadedly connected to the sliding seat 2 822. Two sliding sleeves 823 are slidingly provided with left and right symmetrical sleeves. The two sliding sleeves 823 are hinged with support plates 824. The upper side of the support plate 824 is fixedly connected to the corresponding chest lifter 9. The upper side of the sliding seat 2 822 and the corresponding support plate 824 are jointly hinged with an oblique support plate 825. The oblique support plate 825 is located on the side of the sliding sleeve 823 close to the middle of the corresponding connecting seat 813.

[0040] See Figure 6 and Figure 7The upper side of the sliding sleeve 823 is threaded with a locking bolt 5 826. The upper side of the connecting seat 813 is provided with a plurality of symmetrical through holes 7. The locking bolts 5 826 are movably inserted into the corresponding through holes 7. When needed, after releasing the locking bolt 5 826, the sliding sleeve 823 can be pushed to move by the cooperation of the sliding seat 2 822 and the diagonal support plate 825 while rotating the screw rod 821, so that the sliding sleeve 823 and the sliding seat 2 822 move simultaneously, thereby fine-tuning the distance between the adjacent left and right chest lifters 9. The locking bolt 5 826 can then be rotated to re-lock the sliding sleeve 823. In addition, the screw rod 821 can be rotated alone, so that the sliding seat 2 822 moves, pushing the diagonal support plate 825 to rotate, thereby pushing the support plate 824 to rotate, thereby changing the angle of the support surface of the chest lifter 9, thereby adapting the chest lifter 9 to the patient's body shape and improving the patient's comfort during use. In addition, a triangular support structure is formed between the support plate 824, the sliding sleeve 823, the second sliding seat 822, the diagonal support plate 825 and the connecting seat 813, thereby improving the stability of the chest lifting device 9 during use.

[0041] See Figure 4 、 Figure 6 and Figure 7 The transmission assembly 83 includes a second rotating shaft 831, which is pivotally mounted on the right slide 1 811 via an ear plate. The adjacent first rotating shaft 812 and second rotating shaft 831 are connected by a bevel gear set 832. A rectangular columnar transmission rod 833 is fixedly connected to the adjacent ends of the two second rotating shafts 831. The end of each transmission rod 833, which is away from the corresponding bevel gear set 832, defines a rectangular slot extending along its length. One end of the other transmission rod 833 is slidably inserted into the slot. The two transmission rods 833 are able to slide relative to each other when the two chest lifters 9 approach each other.

[0042] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 10 The driving assembly 84 includes a transmission gear 841, which is coaxially fixed on the rotating shaft 812 on the left front side. A tooth plate 842 engaged with the transmission gear 841 is fixed on the lower end surface of the head bed plate 7 near the rear side, and the tooth plate 842 is located on the upper side of the transmission gear 841.

[0043] During specific operation, under normal conditions, the head bed board 7, the main bed board 3 and the tail bed board 5 are spliced ​​together to form a traditional operating table (such as Figure 10 As shown), at this time, the four chest lifters 9 are hidden under the main beam 6 and will not affect the conventional operation.

[0044] Under special circumstances, such as posterior thoracic and lumbar spine surgery, the headrest board 7 can be unlocked by rotating the locking bolt 2 11, allowing the headrest board 7 to move forward and separate from the main bed board 3. During the movement of the headrest board 7, the tooth plate 842 on the lower side will gradually approach the transmission gear 841 and eventually drive the transmission gear 841 to rotate, so that the transmission gear 841 can drive the rotating shaft 1 812 to rotate, thereby rotating the front connecting seat 813. The rotating shaft 1 812 on the right side of the front connecting seat 813 cooperates with the corresponding bevel gear set 832, so that the front and rear connecting seats 813 can rotate synchronously, automatically transferring the four chest lifters 9 originally hidden under the main beam 6 to the top of the main beam 6. The locking bolt 2 11 is then plugged into the corresponding through hole 7 on the front side of the main beam 6 to lock the headrest board 7 again. At this time, the patient can lie on the four chest lifters 9 for surgery.

[0045] It should be noted that in order to improve the overall structural strength of the head bed board 7 and the main beam 6 after being separated and locked from the main bed board 3, an inclined reinforcing rib can be set between the lower side of the front end of the main beam 6 and the fixed section of the hydraulic lifting device 2. The reinforcing rib, the main beam 6 and the hydraulic lifting device 2 form a triangular structure. The upper end of the inclined reinforcing rib is located in front of the front slide 811 to avoid blocking the movement of the slide 811. The lower end of the inclined reinforcing rib is movably connected to the fixed part of the hydraulic lifting device 2 to adapt to the height changes of the entire operating bed; the reinforcing rib is not shown in the figure.
