Detailed implementation manners

[0029] The following is a further detailed description of the present invention with reference to the attached Figures 1 - 11 drawings.

[0030] Please refer to Figure 1 , Figure 2 and Figure 5 , an electric liftable operating table, including a hydraulic lifting device 2 fixed to the ground through a base 1, the output shaft of the hydraulic lifting device 2 is connected with a main bed board 3, the rear side of the main bed board 3 is connected with a tail bed board 5 through a connecting mechanism one 4, the connecting mechanism one 4 includes a connecting plate one 41 which is fixedly arranged on the lower rear end surface of the main bed board 3 and has an L-shaped structure, a guiding seat 42 is fixedly arranged on the connecting plate one 41, a through hole one penetrating through its lower side is opened on the upper side of the guiding seat 42, a connecting column 43 is slidably arranged in the through hole one, the upper side of the connecting column 43 is rotatably connected with the lower end surface of the tail bed board 5, through holes two are jointly opened between the left and right sides of the horizontal section of the connecting plate one 41 and the left and right sides of the guiding seat 42, a limiting plate 44 is movably inserted in the through hole two, two symmetrically arranged locking bolts one 45 are threadedly connected to the horizontal section of the connecting plate one 41, the lower ends of the locking bolts one 45 movably penetrate through the limiting plate 44, a through hole three penetrating through its right side is opened at a position near the lower side on the left side of the connecting column 43, and the through hole three is adapted to the limiting plate 44.

[0031] Refer to Figure 1 ,Figure 2 , Figure 5 and Figure 11 , a second connecting plate 46 is fixedly connected to the guide seat 42 and is located above the horizontal section of the first connecting plate 41. A fourth through hole extending along its length direction is formed between the upper side and the lower side of the second connecting plate 46. A third connecting plate 47 is hinged to the lower side of the tailstock plate 5. The third connecting plate 47 is movably arranged in the fourth through hole. Through holes five extending along its length direction are formed on both the left side and the right side of the second connecting plate 46. The through holes five communicate with the fourth through hole. A locking rod 48 is commonly arranged between the two through holes five. A plurality of through holes six distributed along its length direction are commonly formed between the left side and the right side of the third connecting plate 47. The locking rod 48 movably penetrates through the corresponding through holes six. Baffles are arranged at both ends of the locking rod 48. 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 state, the tailstock plate 5 and the main bedplate 3 are horizontally placed. The limit on the third connecting plate 47 can be released by rotating the baffle on the locking rod 48 and pulling out the locking rod 48 from the through hole five. Push the tailstock plate 5 upward from the rear side of the tailstock plate 5. After the tailstock plate 5 rotates by a certain angle, at this time, insert the locking rod 48 into the through hole five again and pass through the through hole on the third connecting plate 47 to limit the third connecting plate 47 again, so that the tailstock plate 5 maintains a tilted state, which is convenient for adapting to the body position requirements during some operations.

[0033] During some special operations, such as posterior thoracolumbar spine surgery, it is necessary to support the patient's legs after lying prone. At this time, first remove the locking rod 48, and then rotate the first locking bolt 45 to pull out the limiting plate 44 from the through hole two, so that the connecting column 43 can slide relative to the guide seat 42. At this time, lift the tailstock plate 5 to a certain height, then pull out the connecting column 43 and horizontally rotate the tailstock plate 5 by 180° so that the tailstock plate 5 overlaps with the rear half part of the main bedplate 3 (as shown in Figure 11 ), at this time, the second connecting plate 46, the third connecting plate 47, and the locking rod 48 are located in the corresponding storage grooves formed on the main bedplate 3. Then insert the connecting column 43 into the guide seat 42 so that the through hole three on the connecting column 43 is inside the guide seat 42. After inserting the limiting plate 44 into the through hole three, lock it with the first locking bolt 45, so as to raise the rear half part of the main bedplate 3. After the patient lies prone, place the feet on the tailstock plate 5 at this time and place the knees on the main bedplate 3, so that the patient's legs form an inclined body position. When the legs are slightly inclined, especially when the knees and hips are appropriately bent, the tension of the patient's leg muscles can be reduced, and the lying prone posture of the patient is more stable and comfortable. This stable posture is beneficial to ensuring the accuracy of the operation.

[0034] Refer to Figure 1 , Figure 2 ,Figure 3 , Figure 4 , on the front side of the main bed board 3, there are two main beams 6 that are symmetrically arranged left and right. A head bed board 7 is slidably arranged on the two main beams 6 together, and a second connecting mechanism 8 is arranged between the two main beams 6 together. Four chest lifters 9 are arranged on the second connecting mechanism 8.

[0035] Refer to Figure 1 , Figure 4 , Figure 6 and Figure 10 , the second connecting mechanism 8 includes two slide rail assemblies 81. The two slide rail assemblies 81 are both arranged between the two main beams 6 and are distributed front and back. An adjustment component 82 is arranged on the slide rail assembly 81. The adjustment component 82 is connected to the corresponding two chest lifters 9, and a transmission component 83 is arranged on the right side of the two slide rail assemblies 81 together. A driving component 84 is arranged between the slide rail assembly 81 at the front side and the head bed board 7 together. When the head bed board 7 moves backward along the main beam 6, it controls the driving component 84 to act. The driving component 84 cooperates with the transmission component 83 to enable the two slide rail assemblies 81 to rotate, so as to control the four chest lifters 9 that were originally above the main beam 6 to be able to rotate and then switch to below the main beam 6 for hiding.

[0036] Refer to Figure 1 , Figure 4 , Figure 8 , Figure 9 and Figure 10 , on the left and right sides of the two main beams 6, guide grooves one with a stepped cross-section are opened. On the lower side of the head bed board 7, guide bars one 10 that are symmetrically arranged left and right and are adapted to the guide grooves one are fixedly arranged. The guide bars one 10 are slidably arranged in the guide grooves one. Locking bolts two 11 are threadedly arranged at the rear parts of the left and right sides of the head bed board 7. On the mutually separated sides of the two main beams 6, two through holes seven that are symmetrically arranged front and back are opened. The locking bolts two 11 are movably inserted into the corresponding through holes seven. The head bed board 7 stably moves back and forth along the main beam 6 through the guide bars one 10, and the head bed board 7 is limited between the main beams 6 through the locking bolts two 11.

[0037] Refer to Figure 4 , Figure 6 and Figure 7 , the slide rail assembly 81 includes two slide seats one 811. The two slide seats one 811 are respectively slidably arranged on the corresponding main beam 6. On the mutually approaching sides of the two left and right corresponding slide seats one 811, a rotating shaft one 812 is rotatably arranged. The mutually approaching ends of the two left and right corresponding rotating shafts one 812 are fixedly connected together with a connecting seat 813. The adjustment component 82 is arranged on the connecting seat 813.

[0038] Refer to Figure 2 , Figure 6 , Figure 7 , Figure 8 and Figure 9, on both the left and right sides of the main beam 6 and below the first guide rail groove, there are second guide rail grooves with a stepped cross-section. A second guide bar 12 is slidably arranged in the second guide rail groove, and two adjacent second guide bars 12 are fixedly connected to the same first sliding seat 811. On the mutually remote sides of the two first sliding seats 811 located at the front side, there are third locking bolts 13 threadedly arranged. The third locking bolts 13 are movably inserted into the side wall of the corresponding main beam 6. On the mutually remote sides of the two first sliding seats 811 located at the rear side, there are fourth locking bolts 14 threadedly arranged. One end of the fourth locking bolts 14 is movably abutted against the side wall of the corresponding main beam 6. It should be specifically noted that during installation, after the two first sliding seats 811 located at the front side are installed and fixed on the main beam 6 through the third locking bolts 13, they will no longer move. Although the first sliding seats 811 located at the rear side are fixed on the main beam 6 through the fourth locking bolts 14, when needed, the fourth locking bolts 14 can be rotated reversely so that they are not tightly abutted against the side wall of the corresponding main beam 6, enabling the first sliding seats 811 at the rear side to stably move back and forth along the main beam 6 through the second guide bars 12 and drive the corresponding connecting seats 813 to move, adjusting the distance between the two connecting seats 813 at the front and rear. After reaching the specified position, the fourth locking bolts 14 are used for locking again. At the same time, the connecting seat 813 can also rotate relative to the first sliding seat 811 through the first rotating shaft 812, thereby adjusting the distance between the two thoracic lifters 9 at the rear side and the two thoracic lifters 9 at the front side.

[0039] Refer to Figure 4 , Figure 6 and Figure 7 , a chute is provided on the upper side of the connecting seat 813. The adjusting assembly 82 includes a screw rod 821 rotatably arranged in the chute. The screw rod 821 is provided with two threaded sections with opposite thread directions, and both threaded sections are threadedly connected with second sliding seats 822. On the connecting seat 813, there are two symmetrically arranged sliding sleeves 823 slidably arranged. On both sliding sleeves 823, there are support plates 824 hinged. The upper side of the support plate 824 is fixedly connected to the corresponding thoracic lifter 9. Between the upper side of the second sliding seat 822 and the corresponding support plate 824, there is an inclined support plate 825 hinged. The inclined support plate 825 is located on the side of the sliding sleeve 823 close to the middle of the corresponding connecting seat 813.

[0040] Refer to Figure 6 and Figure 7, a locking bolt five 826 is threadedly arranged on the upper side of the sliding sleeve 823, and a plurality of symmetrically arranged through holes seven are formed on the upper side of the connecting seat 813. The locking bolt five 826 is movably inserted into the corresponding through hole seven. When needed, after releasing the limit of the locking bolt five 826, the sliding sleeve 823 can be pushed to move by the cooperation of the sliding seat two 822 and the diagonal support plate 825 while rotating the screw rod 821, so that the sliding sleeve 823 and the sliding seat two 822 move simultaneously, thereby finely adjusting the distance between two adjacent left and right chest lifters 9, and then rotating the locking bolt five 826 to lock the sliding sleeve 823 again. In addition, the screw rod 821 can be rotated alone to make the sliding seat two 822 move to push the diagonal support plate 825 to rotate, thereby pushing the support plate 824 to rotate, so as to change the angle of the support surface of the chest lifter 9, so as to adapt to the body type requirements of the patient and improve the comfort of the patient during use. And a triangular support structure is formed between the support plate 824, the sliding sleeve 823, the sliding seat two 822, the diagonal support plate 825 and the connecting seat 813, improving the stability of the chest lifter 9 during use.

[0041] Refer to Figure 4 , Figure 6 and Figure 7 , the transmission assembly 83 includes a rotating shaft two 831 rotatably arranged on the right sliding seat one 811 through an ear plate. The adjacent rotating shaft one 812 and the rotating shaft two 831 are commonly connected by a bevel gear set 832. Rectangular column-shaped transmission rods 833 are fixedly connected to the mutually approaching ends of the two rotating shafts two 831. A slot extending along its length direction and having a rectangular structure is formed at one end of any one of the transmission rods 833 away from the corresponding bevel gear set 832, and one end of the other transmission rod 833 is slidably inserted into the slot. The two transmission rods 833 can relatively slide when the two chest lifters 9 approach each other.

[0042] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 10 , the driving assembly 84 includes a transmission gear 841. The transmission gear 841 is coaxially and fixedly arranged on the left front rotating shaft one 812. A toothed plate 842 meshing with the transmission gear 841 is fixedly arranged at a position near the rear side of the lower end surface of the head bed plate 7, and the toothed plate 842 is located above the transmission gear 841.

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

[0044] In special cases, such as posterior thoracolumbar surgery, the locking of the head bedplate 7 can be released by rotating the locking bolt II 11, enabling the head bedplate 7 to move forward so that the head bedplate 7 is separated from the main bedplate 3. During the movement of the head bedplate 7, the toothed plate 842 on its lower side will gradually approach the transmission gear 841 and finally drive the transmission gear 841 to rotate, enabling the transmission gear 841 to drive the rotating shaft I 812 to rotate, thereby causing the front connecting seat 813 to rotate. With the cooperation of the corresponding bevel gear set 832, the two front and rear connecting seats 813 can rotate synchronously, automatically transferring the four thoracic lifters 9 originally hidden under the main beam 6 to directly above the main beam 6. Then, the locking bolt II 11 is inserted into the corresponding through hole VII on the front side of the main beam 6 to lock the head bedplate 7 again. At this time, the patient can lie prone on the four thoracic lifters 9 for the operation.

[0045] It should be noted that in order to improve the overall structural strength of the head bedplate 7 and the main beam 6 after separation and locking from the main bedplate 3, an inclined reinforcing rib can be provided between the lower front side 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 sliding seat I 811 to avoid blocking the movement of the sliding seat I 811, and 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 change of the entire operating bed; the reinforcing rib is not shown in the figure.

[0046] The above are only embodiments of the present invention and do not limit the patent scope of the present invention.
