The dissecting table is composed of a bed bottom frame 1, four rotating plates 19, a bed body 4, and a plurality of pads 27 with mattresses 26. By using the existing servo motor circuit control technology, the first motor 10 is started to rotate the worm 12 driving the worm wheel 13 and the double-threaded rod 14, so that the U-shaped screw blocks 16 at both ends are displaced in the opposite direction, and the first rotating shaft 17 is moved to move the first The two rotating plates 19 on the rotating shaft 17 move synchronously, and then the angle between the rotating plate 19 and the cross plate 8 can be adjusted, so as to achieve the purpose of lifting the bed body 4, so that the bed body 4 is moved to the same height as the mobile patient bed, and then the bottom plate 24 with multiple pads 27 is placed and horizontally slid along the two horizontal guide rails 5 installed on the bed body 4, so that the bottom plate 24 is moved to the mobile patient bed, and then the position of the surgical patient can be changed between the mobile patient bed and the dissection table. There is no need for medical staff to hold the patient, which greatly reduces the workload of medical staff, and can minimize the changes in the body posture of the surgical patient, effectively protecting the wound suture surface.
[0019] Reference Figure 2 and Figure 3There are two cross slots 9 on both sides of the bed bottom frame 1. The cross slots 9 are slidably arranged on the cross block 18. When the first rotating shaft 17 moves with the corresponding U-shaped screw block 16, the cross blocks 18 connected by rotation at both ends of the first rotating shaft 17 slide along the cross slot 9, thereby enabling the first rotating shaft 17 to achieve a horizontal movement effect.
[0020] Reference Figure 2 and Figure 3 The two rotating plates 19 and the bed body 4 are distributed in a trapezoidal structure. Two guide grooves 21 are provided at both ends of the protective cover 3. The rotating plate 19 is slidably installed along the guide grooves 21, and the maximum angle between the rotating plate 19 and the cross plate 8 is 90°. When each rotating plate 19 rotates along the first rotating shaft 17, it can move along the corresponding guide groove 21 provided on the protective cover 3. The guide groove 21 can be used to limit the maximum rotation angle of the rotating plate 19, so that the maximum angle between the rotating plate 19 and the cross plate 8 is 90°.
[0021] Reference Figure 2 and Figure 3 The housing of the first motor 10 is mounted on a first U-shaped block 11 through a bolt thread. The thread directions at both ends of the double-headed threaded rod 14 are opposite and are used for the reverse displacement of the two U-shaped screw blocks 16. The first motor 10 is limitedly mounted on a first U-shaped block 11, which can stably drive the worm 12 to rotate, and then the double-headed threaded rod 14 stably drives the U-shaped screw blocks 16 at both ends to reversely displace through the worm gear 13.
[0022] Reference Figure 1 and Figure 4 The two end surfaces of the bed body 4 are fixed with push handles 22, and a concave groove 23 is provided on the bed body 4. The bottom plate 24 is accommodated in the concave groove 23. By providing two push handles 22, the entire dissecting table can be easily pushed, so that the dissecting table can be moved to a suitable position in the operating room. The bottom plate 24 slides along the two horizontal guide rails 5 through the concave slide 28 and can be accommodated in the concave groove 23 on the bed body 4, so that the pad 27 is level with the surface of the bed body 4.
[0023] Reference Figure 1 and Figure 4 A fixed block 29 is fixed on the bottom surface of the concave slide 28, and a second motor 30 is installed on the bottom surface of the bed body 4. A screw rod 31 is fixed on the output end of the second motor 30. The screw rod 31 is rotatably connected to the bed body 4, and the screw rod 31 threadedly penetrates the fixed block 29. Start the second motor 30, and the fixed block 29 drives the concave slide 28 to slide along the two horizontal guide rails 5 through the screw rod 31.
[0024] Working principle: The dissecting table is composed of a bed bottom frame 1, four rotating plates 19, a bed body 4 and a plurality of pads 27 with mattresses 26. Through the existing servo motor circuit control technology, the first motor 10 is started to rotate the worm 12 to drive the worm wheel 13 and the double-headed threaded rod 14, so that the U-shaped screw blocks 16 at both ends are displaced in the opposite direction, and the first rotating shaft 17 is moved to make the two rotating plates 19 on the first rotating shaft 17 move synchronously, and then the angle between the rotating plate 19 and the cross plate 8 can be adjusted. Because the rotating plates 19 at both ends of the double-headed threaded rod 14 are tilted and distributed in an isosceles trapezoidal structure, when the first motor 10 is turned off, the purpose of lifting the bed body 4 is achieved, so that the bed body 4 is moved to the same height as the mobile bed, and the worm 12 and the worm wheel 13 are rotated. The self-locking property can realize the limiting processing of the rotating plate 19 through the double-headed threaded rod 14, and then stably support the bed body 4, start the second motor 30, and drive the fixed block 29 to drive the concave slide 28 to slide along the two horizontal guide rails 5 through the screw rod 31. The bottom plate 24 with multiple pads 27 installed is horizontally slid and displaced through the concave slide 28. Multiple pads 27 are placed and installed on the bottom plate 24 through multiple rectangular grooves 25, so that the bottom plate 24 is moved to the mobile bed, and then the position of the surgical patient can be changed between the mobile bed and the dissection table. There is no need for medical staff to hold the patient, which greatly reduces the workload of medical staff, and can minimize the changes in the body posture of the surgical patient, effectively protecting the wound suture surface.
