[0006] Preferably, the driving assembly includes a first screw rod, the first screw rod is fixedly connected to the output end of the motor, the outer ring of the top of the first screw rod is threadedly connected to the first nut pair, the first nut pair is internally penetrated and slidably connected to the first guide column, and the first guide column is fixedly connected to the inside of the fixed column, the top of the first nut pair is fixedly connected to the first connecting column, the top of the first connecting column is fixedly connected to the pushing plate, and the pushing plate is rotatably connected to the inside of the telescopic column, the outer ring of the first screw rod is fixedly connected to the driving pulley, and the fixed column is rotatably connected to the inside of the fixed column at the left front end, the outer ring of the second screw rod is fixedly connected to the driven pulley, a belt is provided between the driving pulley and the driven pulley, the outer ring of the top of the second screw rod is threadedly connected to the second nut pair, the second nut pair is internally penetrated and slidably connected to the second guide column on both sides, and the second guide column is fixedly connected to the inside of the fixed column, and the top of the second nut pair is fixedly connected to the second connecting column.

[0007] Preferably, the outer ring at the bottom of the first screw rod is fixedly connected with a third bevel gear, the outer wall of the third bevel gear is meshingly connected with a second bevel gear, and the second bevel gear is rotationally connected to the inside of the left fixed column.

[0008] Preferably, a rotating disk is fixedly connected to the top of the second connecting column, and the rotating disk is fixedly connected to the inner wall of the telescopic column, and a magnet is fixedly connected to the outer wall of the second nut pair.

[0009] Preferably, an electromagnet is adsorbed on the outer wall of the magnet, and the electromagnet is fixedly connected to the inner wall of the telescopic column.

[0010] Preferably, a pentagonal fixing column is fixedly connected inside the second bevel gear, and a pentagonal telescopic column is slidably connected to the inner wall of the pentagonal fixing column.

[0011] Preferably, a first bevel gear is fixedly connected to the right side of the pentagonal telescopic column, and the first bevel gear is rotatably connected to the inside of the right fixed column, and a fourth bevel gear is meshingly connected to the outer wall of the first bevel gear.

[0012] Preferably, a cylinder is fixedly connected to the right side of the fixed seat, and an output end of the cylinder is fixedly connected to the movable seat.

[0013] Working principle: The cylinder is fixed on the right side of the fixed seat, and its output end is connected to the moving seat. When it is necessary to adjust the distance between the fixed table and the moving table, the cylinder expands and contracts, pushing the moving seat to slide along the right side of the top of the base, thereby changing their relative positions to adapt to different patient body types or surgical requirements. When pulling on the pentagonal telescopic column and the pentagonal fixed column, the motor starts, and its output end drives the first lead screw to rotate. The third bevel gear on the outer ring at the bottom of the first lead screw meshes with the second bevel gear. The pentagonal fixed column inside the second bevel gear is slidably connected to the pentagonal telescopic column. The first bevel gear on the right side of the pentagonal telescopic column meshes with the fourth bevel gear, which can achieve power transmission and steering adjustment. When the first lead screw rotates, the first nut pair threadedly connected to the outer ring at its top moves up and down along the inner wall of the fixed column under the guidance of the first guide post. The first connecting column at the top of the first nut pair drives the pushing disk to rotate, and the pushing disk pushes the telescopic column to slide inside the fixed column. At the same time, the driving pulley on the outer ring of the first lead screw drives the driven pulley on the outer ring of the second lead screw to rotate through a belt. The second nut pair on the outer ring of the top thread of the second lead screw moves under the guidance of the second guide post. The second nut pair is derailed from the second guide post, causing the second nut pair to rotate with the second lead screw. The second connecting column at the top of the second nut pair drives the rotating disk to rotate, causing the telescopic column to stop moving upward. The magnet on the outer wall of the second nut pair interacts with the electromagnet on the inner wall of the telescopic column to control the motion control accuracy, enabling the second nut pair to reset. Through the coordinated operation of the above structures, the leg protection pad, head protection pad, chest protection pad, etc. can rise and fall with the telescopic column, realizing multi-angle adjustment of the patient's body position, meeting the requirements for the patient's spinal position at different stages of the operation, and during the adjustment process, each protection pad and strap can effectively fix the patient's body parts, ensuring the safety and smooth progress of the operation.

[0014] The present invention provides a body position transformation assistance device for spinal surgery. It has the following beneficial effects:

[0015] 1. Through the coordinated operation of transmission components such as the motor-driven lead screw, bevel gear, and pulley, the leg protection pad, head protection pad, chest protection pad, etc. of the present invention can rise and fall with the telescopic column. The magnet on the outer wall of the second nut pair interacts with the electromagnet on the inner wall of the telescopic column, not only enhancing the connection stability but also improving the motion control accuracy, making the body position adjustment more precise, facilitating surgical operation, thereby realizing multi-angle adjustment of the patient's body position and meeting the diverse requirements for the patient's spinal position at different stages of the operation.

[0016] 2. By using the cylinder to push the moving seat to change the distance between the fixed table and the moving table, and at the same time cooperating with structures such as the pentagonal telescopic column and the pentagonal fixed column to pull on the telescopic column, the present invention enables the leg, head, chest, etc. protection pads to rise and fall with the telescopic column, capable of multi-angle adjustment of the patient's body position, meeting the diverse requirements for the patient's spinal position due to different patient body type differences and different stages of the operation.

DETAILED DESCRIPTION

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example:

[0027] On the fixing table 4, arm straps 7 are provided at the front and rear ends of the right side, and a waist strap 6 is provided at the middle end. These straps are used to fix the corresponding parts of the patient's body during the operation to prevent the patient's body position from accidentally changing and affecting the operation. The leg straps 17 on the top of the leg protection pad 15 further enhance the fixation effect on the patient's legs. These protection pads can not only provide protection for the key parts of the patient's body during the body position adjustment process to avoid accidental injuries, but also maintain the correct posture of the patient's body during the operation to ensure the exposure of the surgical site and the convenience of operation.

[0028] The driving assembly includes a first screw rod 19, which is fixedly connected to the output end of the motor 18. The outer ring of the top of the first screw rod 19 is threadedly connected to a first nut pair 26. The first nut pair 26 is penetrated and slidably connected to a first guide column 25, and the first guide column 25 is fixedly connected to the inside of the fixed column 12. The top of the first nut pair 26 is fixedly connected to a first connecting column 27, and the top of the first connecting column 27 is fixedly connected to a push plate 28, and the push plate 28 is rotatably connected to the inside of the telescopic column 13. The outer ring of the first screw rod 19 is fixed A driving pulley 29 is connected, and a second screw rod 24 is rotatably connected inside the fixed column 12 at the left front end. A driven pulley 32 is fixedly connected to the outer ring of the second screw rod 24. A belt 30 is arranged between the driving pulley 29 and the driven pulley 32. A second nut pair 34 is threadedly connected to the outer ring of the top of the second screw rod 24. Second guide columns 33 are penetrated and slidably connected inside both sides of the second nut pair 34, and the second guide column 33 is fixedly connected to the inside of the fixed column 12. A second connecting column 31 is fixedly connected to the top of the second nut pair 34.

[0029] When the motor 18 starts to rotate, the first screw 19 rotates accordingly. Since the outer ring of the top of the first screw 19 is threadedly connected to the first nut pair 26, and the first guide column 25 fixed to the inside of the fixed column 12 is penetrated and slidably connected inside the first nut pair 26, the first guide column 25 limits the rotational freedom of the first nut pair 26, so that it can only move up and down along the inner wall of the fixed column 12. The top of the first nut pair 26 is connected to the push disk 28 through the first connecting column 27, and the push disk 28 is rotatably connected to the inside of the telescopic column 13. Therefore, the up and down movement of the first nut pair 26 is converted into the rotation of the push disk 28, which in turn pushes the telescopic column 13 to slide inside the fixed column 12, realizing the lifting and lowering action of the protective pad. When the first screw 19 rotates, the active pulley 29 drives the driven pulley 32 to rotate, so that the second screw 24 rotates synchronously. The second nut pair 34, which is threadedly connected to the outer ring of the top of the second screw rod 24, penetrates on both sides and moves with the second guide column 33 fixed inside the fixed column 12, and the second connecting column 31 at the top of the second nut pair 34 is connected to the rotating disk 21, and the rotating disk 21 is fixed to the inner wall of the telescopic column 13. In certain cases, the second nut pair 34 and the second guide column 33 are derailed, and the second nut pair 34 and the second screw rod 24 rotate, and the telescopic column 13 can be stopped from moving upward through the rotating disk 21, so as to achieve precise control of the movement state of the telescopic column 13, so that the left chest cavity of the patient will not move upward, and the right chest cavity will move upward.

[0030] The outer ring at the bottom of the first screw rod 19 is fixedly connected with the third bevel gear 20 , the outer wall of the third bevel gear 20 is meshedly connected with the second bevel gear 11 , and the second bevel gear 11 is rotatably connected to the inside of the left fixed column 12 .

[0031] The top of the second connecting column 31 is fixedly connected with the rotating disk 21 , and the rotating disk 21 is fixedly connected to the inner wall of the telescopic column 13 . The outer wall of the second nut pair 34 is fixedly connected with the magnet 36 .

[0032] The magnets 36 on both sides of the second guide post 33 have the greatest adsorption force and adsorb with the electromagnet 35 , so that the slot of the second nut pair 34 is aligned with the second guide post 33 , the electromagnet 35 adsorbs, and the second nut pair 34 moves downward and slides with the second guide post 33 .

[0033] The outer wall of the magnet 36 is attracted by the electromagnet 35 , and the electromagnet 35 is fixedly connected to the inner wall of the telescopic column 13 .

[0034] The magnet 36 fixed on the outer wall of the second nut pair 34 and the electromagnet 35 fixed on the inner wall of the telescopic column 13 are attracted to each other. During the operation of the device, this magnetic connection method not only enhances the stability of the connection between the second nut pair 34 and the telescopic column 13, prevents loosening or displacement deviation during movement, but also improves the accuracy of motion control. By accurately controlling the magnetic strength and on-off time of the electromagnet 35, the fine-tuning and precise positioning of the movement of the second nut pair 34 can be achieved, thereby ensuring the position accuracy of the protective pad during the lifting process, making the position adjustment more accurate, and meeting the strict requirements of the surgery on the patient's spinal position.

[0035] A pentagonal fixing column 22 is fixedly connected inside the second bevel gear 11 , and a pentagonal telescopic column 10 is slidably connected to the inner wall of the pentagonal fixing column 22 .

[0036] The pentagonal telescopic column 10 slides on the inner wall of the pentagonal fixed column 22 .

[0037] A first bevel gear 9 is fixedly connected to the right side of the pentagonal telescopic column 10 , and the first bevel gear 9 is rotatably connected to the inside of the right fixed column 12 , and a fourth bevel gear 23 is meshedly connected to the outer wall of the first bevel gear 9 .

[0038] The third bevel gear 20 on the outer ring of the bottom of the first screw 19 meshes with the second bevel gear 11 that is rotatably connected inside the left fixed column 12. The pentagonal fixed column 22 inside the second bevel gear 11 is slidably connected to the pentagonal telescopic column 10, and the first bevel gear 9 on the right side of the pentagonal telescopic column 10 meshes with the fourth bevel gear 23 that is rotatably connected inside the right fixed column 12. This bevel gear transmission structure realizes the transmission and steering adjustment of power, so that the drive component can apply force to the telescopic column 13 in different directions and angles, further enriching the way and flexibility of body position adjustment.

[0039] A cylinder 8 is fixedly connected to the right side of the fixed seat 3 , and an output end of the cylinder 8 is fixedly connected to the movable seat 2 .

[0040] The cylinder 8 connected to the right side of the fixed seat 3 has its output end fixed to the movable seat 2. In actual use, when the distance between the fixed table 4 and the movable table 5 needs to be adjusted to suit different patient sizes or special surgical requirements, the cylinder 8 moves in a telescopic manner, pushing the movable seat 2 to slide along the top right side of the base 1, changing the relative position of the two, providing the patient with a more suitable lying space and position adjustment range, further improving the applicability and flexibility of the device.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
