Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a spinal assistive therapy device for spinal surgery and its operating method. Background Technology

[0002] Spinal assistive therapy devices for spinal surgery are medical devices designed to assist spinal surgery or treatment. These devices aim to improve the precision of surgery, reduce surgical trauma, promote postoperative recovery, and provide better treatment results for patients. Spinal assistive therapy operating tables are the most commonly used medical instruments in spinal surgery. The operating tables are usually driven by electro-hydraulic technology and have stable lifting, tilting, and rotation functions, which can meet the various positional needs during the operation.

[0003] When using an auxiliary operating table for spinal surgery, the patient must first lie face down on the table with their back completely facing upwards to facilitate the surgical procedure. However, most patients requiring spinal surgery do not have the ability to turn over independently. After being lifted onto the operating table, they require assistance from medical staff to turn over. Some patients can only be lifted and turned by medical staff, which consumes a significant amount of manpower and resources. More importantly, it is difficult to turn all parts of the patient's body simultaneously by hand. Improper operation may also cause some degree of damage to the patient's spine, hindering the treatment and recovery of the patient's spine. Summary of the Invention

[0004] This invention addresses the problem that turning patients requires significant manpower, and that manual turning makes it difficult to simultaneously turn different parts of the patient's body. Improper operation may also cause damage to the patient's spine, hindering spinal treatment and recovery. Therefore, this invention proposes a spinal assistive therapy device and its operation method for spinal surgery.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a spinal surgery auxiliary treatment device, comprising a base plate, an electro-hydraulic rod fixedly connected to the top of the base plate, a first bed board fixedly connected to one end of the electro-hydraulic rod, a second bed board and a third bed board fixedly connected to both sides of the first bed board respectively, two pressure blocks provided on the top of the second bed board, an operating frame slidably connected to the top of the base plate, a surgical lamp provided at the bottom of one end of the operating frame, and a rotatable and foldable auxiliary device for assisting the patient to turn over provided on one side of the base plate.

[0006] The effects achieved by the above-mentioned components are as follows: by setting up the auxiliary device, the auxiliary device can drive the patient to rotate as a whole without consuming a lot of manpower and material resources. Moreover, when the auxiliary device turns the patient over, it will turn all parts of the patient's body simultaneously, which helps to prevent damage to the patient's spine and facilitates the treatment and recovery of the patient's spine.

[0007] Preferably, the auxiliary device includes two rectangular cylinders, which are respectively disposed on the side of the second bed board away from the second bed board. One end of each of the two rectangular cylinders is fixedly connected to the same connecting rod. Support rods are fixedly connected to both sides of the bottom of the connecting rod. One end of each of the two support rods is fixedly connected to the same connecting plate. Support plates are symmetrically fixedly connected to one side of the connecting plate. Rectangular rods are slidably connected to the support plates and the inner walls of the rectangular cylinders. One end of each of the two rectangular rods is fixedly connected to the same auxiliary rod. Rotating rods are rotatably connected to the sides of the two auxiliary rods that are close to each other. A U-shaped frame is fixedly connected to one side of the rotating rod. A placement plate is disposed between the two U-shaped frames. Rotating shafts are fixedly connected to both sides of the placement plate. The outer surface of the rotating shafts is rotatably connected to the inner wall of the U-shaped block. A self-locking motor is disposed on one side of one of the U-shaped frames. A pulley is fixedly connected to the output end of the self-locking motor and one end of one of the rotating shafts. A transmission belt is disposed on the outer surface of the two pulleys. An extension rod is fixedly connected to the edge of one side of the U-shaped frame. A first roller is disposed at one end of the extension rod.

[0008] The aforementioned components achieve the following effect: When a patient needs to be turned over, rotating the rotating rod causes the U-shaped frame to rotate. The U-shaped blocks then cause the placement plate connected to the rotating shaft to slide into the extension rod and rotate synchronously until the first roller at one end of the extension rod abuts against the top of the rectangular tube. Then, pushing the auxiliary rod causes two rectangular rods on one side to slide towards the inner wall of the rectangular tube and support plate, and also causes the first roller to move at the top of the rectangular tube until the two rectangular rods are completely inside the inner wall of the rectangular tube and support plate. At this point, the placement plate, driven by the two U-shaped blocks, reaches directly above the second bed board. The patient requiring surgery is then placed on the placement plate and secured to it. The self-locking motor is activated, and its output drives the transmission belt connected to the pulley to rotate. This transmission belt then drives the rotating shaft connected to another transmission belt to rotate. The placement board rotates, causing the patient to rotate as well until their back is completely facing upwards, thus completing the patient's rotation. During rotation, uneven force will not affect the patient's spine. After placing the patient on the first, second, and third bed boards, the placement board needs to be stowed. Rotating the placement board disengages the first roller from its track until the second roller touches the ground. The length of the U-shaped frame is slightly shorter than the width of the placement board, at which point one side of the U-shaped frame aligns with one side of the auxiliary rod, which provides support for the placement board. When the self-locking motor is turned off, its output automatically locks, securing the placement board and U-shaped frame and preventing relative rotation. This facilitates footing by medical staff and allows one side of the treatment device to be raised, aiding in surgical procedures.

[0009] Preferably, the top of the rectangular tube is provided with a track, the size of the first roller is adapted to the size of the inner wall of the track, and one end of the auxiliary rod is fixedly connected to a second roller.

[0010] The effects achieved by the above components are as follows: by setting a track that is compatible with the first roller, the track can limit the first roller, which helps to prevent the first roller from deviating during movement and causing it to detach from the rectangular tube, making the first roller more stable during movement. At the same time, by setting a second roller that abuts against the ground, the second roller can support the auxiliary rod. When the auxiliary rod is pushed, the auxiliary rod will drive the second roller to rotate, which also facilitates the pushing of the placement plate.

[0011] Preferably, a first rotating plate is rotatably connected to one side of the rotating rod, a second rotating plate is rotatably connected to one end of the first rotating plate, one end of the second rotating plate is rotatably connected to the outer surface of the rotating shaft, and auxiliary grooves are provided on both sides of the placement plate, with one end of the second rotating plate disposed inside the auxiliary groove.

[0012] The effect achieved by the above components is as follows: by setting the first rotating plate and the second rotating plate, when the rotating rod is rotated, the rotating rod will drive the first rotating plate and the second rotating plate to rotate, making the placement plate more stable during rotation. In addition, the first rotating plate and the second rotating plate can provide auxiliary support for the placement plate connected to the U-shaped frame, thereby improving the overall structural stability when the placement plate is stored.

[0013] Preferably, elastic straps are symmetrically fixedly connected to both sides of the placement plate, and the same pin is inserted into the inner wall of the two elastic straps. One end of the pin is fixedly connected to one side of the placement plate, and the other end of the pin is fixedly connected to a locking block. The cross-section of the locking block is an isosceles trapezoid.

[0014] The effects achieved by the above components are as follows: by setting elastic straps, it is easy to fix the patient to the placement board. At the same time, by flipping the two elastic straps, the locking block and the pin are inserted into the inner wall of the two elastic straps. One end of the locking block is smaller, which makes it easier to insert the locking block into the inner wall of the two elastic straps. Meanwhile, the other end of the locking block is larger, which can limit the movement between the elastic straps and the pin, which helps to prevent the two elastic straps from dragging on the ground and being stepped on by medical staff.

[0015] Preferably, an adjustment device is provided between the two pressure blocks and the second bed board. The adjustment device includes two sleeves. The pressure blocks are disposed on the top of the sleeves. Slider blocks are symmetrically fixedly connected to both sides of the sleeves. Side plates are fixedly connected to both sides of the second bed board. The outer surface of the slider is slidably connected to the inner wall of the side plate. A triangular block is fixedly connected to the bottom of the pressure block. The outer surface of the triangular block is slidably connected to the inner wall of the sleeve. A trapezoidal block is provided at the bottom of the triangular block. The top of the trapezoidal block abuts against the bottom of the triangular block. The outer surface of the trapezoidal block is slidably connected to the bottom of the inner wall of the sleeve. A threaded rod is fixedly connected to one side of the trapezoidal block. A threaded cylinder is threadedly connected to the outer surface of the threaded rod. The outer surface of the threaded cylinder is rotatably connected to the inner wall of both the sleeve and one of the sliders.

[0016] The aforementioned components achieve the following effects: By setting up a threaded rod and a threaded cylinder, rotating the threaded cylinder causes the threaded rod to extend and retract within the inner wall of the cylinder. During this extension and retraction, the threaded rod causes the trapezoidal block to slide on the bottom of the inner wall of the sleeve. As the trapezoidal block slides, it causes the triangular block to slide within the inner wall of the sleeve. The triangular block then causes the pressure block to move vertically until the top of the pressure block contacts the patient's chest cavity. This allows for adjustments to the height of the pressure block based on the individual patient's physical condition, effectively improving the fit between the patient and the pressure block. This ensures that the pressure block provides good support for the patient's chest cavity and facilitates surgical procedures and related operations for the doctor.

[0017] Preferably, auxiliary cylinders are symmetrically fixedly connected to one side of the bottom of the triangular block, and one side of each of the two auxiliary cylinders abuts against the inner wall of the sleeve. Sliding rods are slidably connected to the inner wall of the auxiliary cylinders, and one end of each of the two sliding rods is fixedly connected to the bottom of the inner wall of the sleeve.

[0018] The effect achieved by the above components is as follows: by setting an auxiliary cylinder and a sliding rod, the auxiliary cylinder is connected to one side of the triangular block, which can ensure that one side of the auxiliary cylinder is always in contact with the inner wall of the sleeve during the adjustment of the triangular block, and can play an auxiliary support role between the triangular block and the inner wall of the sleeve. At the same time, when the triangular block moves under the action of the threaded rod, the triangular block will drive the auxiliary cylinder to slide synchronously on the outer surface of the sliding rod, thereby making the triangular block more stable during the movement.

[0019] Preferably, a gear is rotatably connected to the outer surface of the threaded cylinder, a toothed plate is fixedly connected to one side of the baffle, the outer surface of the gear meshes with the outer surface of the toothed plate, the outer surface of the threaded cylinder is provided with threads, and a nut is threadedly connected to the outer surface of the threaded cylinder.

[0020] The aforementioned components achieve the following effects: By setting a nut and rotating it, the nut disengages from the gear. When the pressure block and sleeve slide against the inner wall of the second bed board, the slider slides synchronously against the inner wall of the groove. The slider drives the gear to move, and the gear, under the action of the gear plate, rotates continuously. This allows for adjustment of the pressure block's position according to the patient's actual needs. Simultaneously, rotating the nut causes one side of the nut to abut against one side of the gear, fixing the threaded cylinder and gear. This prevents the gear from rotating and fixes the slider connected to the threaded cylinder to the side plate, thus fixing the pressure block's position and preventing displacement when the patient's chest cavity is placed on it. It should be noted that when the gear and threaded cylinder are fixed together, the threaded cylinder cannot rotate, and the height of the pressure block cannot be adjusted. Adjustments to the vertical height and horizontal position of the pressure block must be performed separately.

[0021] Preferably, a rubber pad is fixedly connected to one side of the gear, the outer surface of the threaded cylinder is inserted into the inner wall of the rubber pad, an operating block is fixedly connected to one end of the threaded cylinder, and protrusions are evenly distributed on the outer surface of the operating block.

[0022] The effects achieved by the above components are as follows: by setting a rubber pad, one side of the gear can be replaced to abut against the nut, and the friction between the nut and the gear can be increased, which helps to prevent the gear from loosening. At the same time, by setting an operating block, the protrusion on the outer surface of the operating block can increase the friction on the outer surface of the operating block, so that the threaded cylinder is rotated by the operating block. In addition, the operating block can block one end of the threaded cylinder, which helps to prevent the nut from falling off the threaded cylinder due to misoperation.

[0023] Preferably, when it is necessary to turn the patient over, the position of the pressure block needs to be adjusted first. Rotating the nut disengages it from the gear, releasing the gear's limiting position. Then, pushing the pressure block and sleeve to slide along the inner wall of the second bed board causes the slider to slide synchronously along the inner wall of the groove. The slider drives the gear to move, and the gear, under the action of the gear plate, rotates continuously until the pressure block reaches the appropriate position. Next, rotating the rotating rod causes the U-shaped frame to rotate, which in turn causes the first and second rotating plates to rotate. Simultaneously, the U-shaped block drives the device connected to the rotating shaft... The plate slides into the extension rod and rotates synchronously until the first roller at one end of the extension rod abuts against the inner wall of the track at the top of the rectangular tube. Then, the auxiliary rod is pushed, which drives two rectangular rods on one side to slide towards the inner wall of the rectangular tube and the support plate, and drives the first roller to move at the top of the rectangular tube until the two rectangular rods are completely inside the inner wall of the rectangular tube and the support plate. At this time, the placement plate, driven by the two U-shaped blocks, also reaches directly above the second bed board. The patient who needs to be operated on is then placed on the placement plate, and the patient is secured to the placement plate with straps. The self-locking motor is then activated. The output of the self-locking motor drives a transmission belt connected to a pulley to rotate. This transmission belt then drives a shaft connected to another transmission belt to rotate. The shaft rotates the placement plate, causing the patient to rotate until their back is completely facing upwards, thus completing the patient's rotation. Finally, rotating the operating block moves the threaded cylinder, which in turn causes the threaded rod to extend and retract within the cylinder. During this extension and retraction, the threaded rod causes a trapezoidal block to slide at the bottom of the sleeve's inner wall. The trapezoidal block, in turn, causes a triangular block to slide within the sleeve's inner wall. This will cause the auxiliary cylinder to slide synchronously on the outer surface of the slide bar. At the same time, the triangular block will cause the pressure block to move vertically until the top of the pressure block abuts against the patient's chest cavity. Then, the nut is rotated so that one side of the nut abuts against the rubber pad on the side of the gear, which can fix the threaded cylinder and the gear. This will prevent the gear from rotating and fix the slider connected to the threaded cylinder and the side plate, thereby fixing the position of the pressure block. At this time, the elastic straps can be released to limit the patient and the placement board, and the patient can be placed on the first bed board, the second bed board, and the third bed board.

[0024] In summary, the beneficial effects of this invention are as follows:

[0025] By setting up an auxiliary device, including a placement board, the patient can be placed on the placement board. The placement board can rotate the patient as a whole under the action of a self-locking motor, without consuming a lot of manpower and resources. When the auxiliary device turns the patient over, it will turn all parts of the patient's body simultaneously, which helps to prevent damage to the patient's spine and facilitates the treatment and recovery of the patient's spine.

[0026] By setting an adjustment device, which includes a triangular block and a trapezoidal block, the trapezoidal block can drive the pressure block connected to the triangular block to move vertically. This makes it easier to adjust the height of the pressure block according to the different physical conditions of the patients, effectively improving the fit between the patient and the pressure block. This allows the pressure block to provide good support for the patient's chest cavity and also facilitates the doctor's surgery and related operations. Attached Figure Description

[0039] Reference Figures 1-6As shown, this embodiment discloses a base plate 1. An electric hydraulic rod 2 is fixedly connected to the top of the base plate 1. A first bed board 3 is fixedly connected to one end of the electric hydraulic rod 2. A second bed board 4 and a third bed board 5 are fixedly connected to both sides of the first bed board 3, respectively. Two pressure blocks 10 are provided on the top of the second bed board 4. An operating frame 6 is slidably connected to the top of the base plate 1. A surgical lamp 7 is provided at the bottom of one end of the operating frame 6. A rotatable and foldable auxiliary device 8 for assisting the patient to turn over is provided on one side of the base plate 1. The auxiliary device 8 includes two rectangular tubes 81, which are respectively located on the side of the second bed board 4 away from it. A common connecting rod 82 is fixedly connected to one end of each of the two rectangular tubes 81. Both sides of the bottom of the connecting rod 82 are fixedly connected to... Support rods 83 are provided, with one end of each support rod 83 fixedly connected to the same connecting plate 84. Support plates 85 are symmetrically fixedly connected to one side of the connecting plate 84. Rectangular rods 86 are slidably connected to both the support plates 85 and the inner walls of the rectangular tube 81. One end of each rectangular rod 86 is fixedly connected to the same auxiliary rod 87. Rotating rods 88 are rotatably connected to the adjacent sides of each auxiliary rod 87. A U-shaped frame 89 is fixedly connected to one side of each rotating rod 88. A placement plate 810 is provided between the two U-shaped frames 89. Rotating shafts 811 are fixedly connected to both sides of the placement plate 810. The outer surface of the rotating shafts 811 is rotatably connected to the inner wall of the U-shaped block. A self-locking motor 812 is provided on one side of one of the U-shaped frames 89. The output end of the self-locking motor 812 is connected to one of the U-shaped frames 89. Each of the rotating shafts 811 has a pulley 813 fixedly connected to one end. The outer surfaces of the two pulleys 813 are provided with the same transmission belt 814. An extension rod 815 is fixedly connected to one edge of the U-shaped frame 89. One end of the extension rod 815 is provided with a first roller 816. When it is necessary to turn the patient over, rotating the rotating rod 88 will drive the U-shaped frame 89 to rotate. The U-shaped block will drive the placement plate 810 connected to the rotating shaft 811 to slide into the extension rod 815 and rotate synchronously until the first roller 816 at one end of the extension rod 815 abuts against the top of the rectangular tube 81. Then, pushing the auxiliary rod 87 will drive the two rectangular rods 86 on one side to slide towards the inner wall of the rectangular tube 81 and the support plate 85, and drive the first roller. 816 moves at the top of the rectangular tube 81 until the two rectangular rods 86 are fully inserted into the inner walls of the rectangular tube 81 and the support plate 85, respectively. At this time, the placement plate 810, driven by the two U-shaped blocks, also reaches directly above the second bed board 4. The patient to be operated on is then placed on the placement plate 810 and secured to it. The self-locking motor 812 is then activated. The output of the self-locking motor 812 drives the transmission belt 814 connected to the pulley 813 to rotate. The transmission belt 814 drives the rotating shaft 811 connected to another transmission belt 814 to rotate. The rotating shaft 811 drives the placement plate 810 to rotate, and thus rotates the patient as a whole, until the patient's back is completely facing upwards, completing the patient's rotation.When the placement plate 810 is rotated on the patient, it will not affect the patient's spine due to uneven force. After the patient is placed on the first bed board 3, the second bed board 4, and the third bed board 5, the placement plate 810 needs to be stored. Rotating the placement plate 810 causes the first roller 816 to disengage from the track 817 until the second roller 818 touches the ground. The length of the U-shaped frame 89 is slightly shorter than the width of the placement plate 810. At this time, one side of the U-shaped frame 89 just touches one side of the auxiliary rod 87, which provides support for the placement plate 810. When the self-locking motor 812 is turned off, its output end automatically locks, thus fixing the placement plate 810 and the U-shaped frame 89 and preventing relative rotation between them. This facilitates stepping on the device by medical staff and allows one side of the treatment device to be raised, making surgical operations easier for some medical staff.

[0040] Reference Figures 1-6 As shown, this embodiment discloses a track 817 provided at the top of the rectangular tube 81. The size of the first roller 816 is adapted to the size of the inner wall of the track 817. One end of the auxiliary rod 87 is fixedly connected to a second roller 818. By setting the track 817, the track 817 is adapted to the first roller 816, thereby limiting the first roller 816. This helps prevent the first roller 816 from shifting during movement and causing it to detach from the rectangular tube 81, making the first roller 816 more stable during movement. At the same time, by setting the second roller 818, which abuts against the ground, the second roller 818 can support the auxiliary rod 87. When the auxiliary rod 87 is pushed, it will drive the second roller 818 to rotate, which also facilitates the placement of the plate 810. The rotating rod 88 is rotatably connected to a first rotating plate 819 on one side, and a second rotating plate 820 is rotatably connected to one end of the first rotating plate 819. One end of the second rotating plate 820 is rotatably connected to the outer surface of the rotating shaft 811. Auxiliary grooves 821 are provided on both sides of the placement plate 810. One end of the second rotating plate 820 is located inside the auxiliary groove 821. By setting the first rotating plate 819 and the second rotating plate 820, when the rotating rod 88 is rotated, the rotating rod 88 will drive the first rotating plate 819 and the second rotating plate 820 to rotate, making the placement plate 810 more stable during rotation. The first rotating plate 819 and the second rotating plate 820 can provide auxiliary support for the placement plate 810 connected to the U-shaped frame 89, thereby improving the overall structural stability when the placement plate 810 is stored.

[0041] Reference Figures 1-6As shown, this embodiment discloses that elastic straps 822 are symmetrically fixedly connected to both sides of the placement plate 810. The same pin 823 is inserted into the inner wall of the two elastic straps 822. One end of the pin 823 is fixedly connected to one side of the placement plate 810, and the other end of the pin 823 is fixedly connected to a locking block 824. The cross-section of the locking block 824 is an isosceles trapezoid. By setting the elastic straps 822, it is convenient to fix the patient to the placement plate 810. At the same time, the two elastic straps 822 are flipped, and the locking block 824 and the pin 823 are inserted into the inner wall of the two elastic straps 822. One end of the locking block 824 is smaller, which makes it easier to insert the locking block 824 into the inner wall of the two elastic straps 822. At the same time, the other end of the locking block 824 is larger, which can limit the movement between the elastic straps 822 and the pin 823, which helps to prevent the two elastic straps 822 from dragging on the ground and being stepped on by medical staff.

[0042] Reference Figures 7-10As shown, this embodiment discloses an adjusting device 9 disposed between two pressure blocks 10 and a second bed board 4. The adjusting device 9 includes two sleeves 91. The pressure blocks 10 are disposed on the top of the sleeves 91. Slider blocks 92 are symmetrically fixedly connected to both sides of the sleeves 91. Side plates 93 are fixedly connected to both sides of the second bed board 4. The outer surface of the sliders 92 is slidably connected to the inner wall of the side plates 93. A triangular block 94 is fixedly connected to the bottom of the pressure blocks 10. The outer surface of the triangular block 94 is slidably connected to the inner wall of the sleeves 91. A trapezoidal block 95 is disposed at the bottom of the triangular block 94. The top of the trapezoidal block 95 abuts against the bottom of the triangular block 94. The outer surface of trapezoidal block 95 is slidably connected to the bottom of the inner wall of sleeve 91. A threaded rod 96 is fixedly connected to one side of trapezoidal block 95. A threaded cylinder 97 is threadedly connected to the outer surface of threaded rod 96. The outer surface of threaded cylinder 97 is rotatably connected to the inner walls of sleeve 91 and one of the sliders 92. By setting threaded rod 96 and threaded cylinder 97, rotating threaded cylinder 97 will cause threaded rod 96 to extend and retract on the inner wall of threaded cylinder 97. During the extension and retraction of threaded rod 96, trapezoidal block 95 will slide on the bottom of the inner wall of sleeve 91. During the movement of slider 92, trapezoidal block 95 will cause triangular block 94 to move on sleeve 91. The inner wall slides, and the triangular block 94 moves the pressure block 10 vertically until the top of the pressure block 10 abuts against the patient's chest cavity. This allows for adjustment of the height of the pressure block 10 according to different patients' physical conditions, effectively improving the fit between the patient and the pressure block 10. This ensures that the pressure block 10 provides good support for the patient's chest cavity and facilitates surgery and related procedures for the doctor. Auxiliary cylinders 98 are symmetrically fixed to one side of the bottom of the triangular block 94. One side of each auxiliary cylinder 98 abuts against the inner wall of the sleeve 91. A sliding rod 99 is slidably connected to the inner wall of the auxiliary cylinders 98. One end of each slide rod 99 is fixedly connected to the bottom of the inner wall of the sleeve 91. By setting an auxiliary cylinder 98 and slide rod 99, the auxiliary cylinder 98 is connected to one side of the triangular block 94. During the adjustment of the triangular block 94, it can ensure that one side of the auxiliary cylinder 98 is always in contact with the inner wall of the sleeve 91, which can play an auxiliary support role between the triangular block 94 and the inner wall of the sleeve 91. At the same time, when the triangular block 94 moves under the action of the threaded rod 96, the triangular block 94 will drive the auxiliary cylinder 98 to slide synchronously on the outer surface of the slide rod 99, thereby making the triangular block 94 more stable during the movement.

[0043] Reference Figures 7-10As shown, this embodiment discloses a gear 910 rotatably connected to the outer surface of the threaded cylinder 97, a toothed plate 911 fixedly connected to one side of the baffle, the outer surface of the gear 910 meshing with the outer surface of the toothed plate 911, the outer surface of the threaded cylinder 97 being threaded, and a nut 912 being threadedly connected to the outer surface of the threaded cylinder 97. By setting the nut 912, rotating the nut 912 causes it to disengage from the gear 910. When the pressure block 10 and the sleeve 91 slide against the inner wall of the second bed plate 4, the slider 92 will slide synchronously against the inner wall of the groove. 2 will drive gear 910 to move, and gear 910, under the action of gear plate 911, will rotate continuously, thus facilitating the corresponding adjustment of the position of pressure block 10 according to the actual needs of the patient. At the same time, rotating nut 912 will cause one side of nut 912 to abut against one side of gear 910, thereby fixing the threaded cylinder 97 and gear 910. This will prevent gear 910 from rotating, thus fixing the slider 92 connected to the threaded cylinder 97 and the side plate 93, thereby fixing the position of pressure block 10. This design helps prevent the pressure block 10 from shifting when the patient's chest cavity is cushioned on it. It's important to note that when the gear 910 and the threaded cylinder 97 are fixed together, the threaded cylinder 97 cannot be rotated, and the height of the pressure block 10 cannot be adjusted. Adjustments to the vertical height and horizontal position of the pressure block 10 must be performed separately. A rubber pad 913 is fixedly connected to one side of the gear 910. The outer surface of the threaded cylinder 97 is inserted into the inner wall of the rubber pad 913. An operating block 914 is fixedly connected to one end of the threaded cylinder 97. The outer surface of the operating block 914 is evenly provided with protrusions. By setting a rubber pad 913, one side of the gear 910 can be replaced to abut against the nut 912, and the friction between the nut 912 and the gear 910 can be increased, which helps to prevent the fixed limit of the gear 910 from loosening. At the same time, by setting an operating block 914, the protrusion on the outer surface of the operating block 914 can increase the friction on the outer surface of the operating block 914, so that the threaded cylinder 97 is rotated through the operating block 914, which has an anti-slip effect. In addition, the operating block 914 can block one end of the threaded cylinder 97, which helps to prevent the nut 912 from disengaging from the threaded cylinder 97 due to misoperation.

[0044] The working principle is as follows: When it is necessary to turn the patient over, the position of the pressure block 10 needs to be adjusted first. Rotating the nut 912 disengages it from the gear 910, releasing the limiting effect on the gear 910. Then, when the pressure block 10 and sleeve 91 slide against the inner wall of the second bed board 4, the slider 92 will slide synchronously against the inner wall of the groove. The slider 92 will drive the gear 910 to move, and under the action of the toothed plate 911, the gear 910 will continuously... Rotate until the pressure block 10 reaches the appropriate position; then, rotate the rotating rod 88, which will drive the U-shaped frame 89 to rotate, and will also drive the first rotating plate 819 and the second rotating plate 820 to rotate. At the same time, the U-shaped block will drive the placement plate 810 connected to the rotating shaft 811 to slide into the extension rod 815 for synchronous rotation, until the first roller 816 at one end of the extension rod 815 abuts against the inner wall of the track 817 at the top of the rectangular tube 81. Then push the auxiliary rod 87, which will drive one side The two rectangular rods 86 slide towards the inner walls of the rectangular tube 81 and the support plate 85, and drive the first roller 816 to move at the top of the rectangular tube 81 until the two rectangular rods 86 are completely inside the inner walls of the rectangular tube 81 and the support plate 85. At this time, the placement plate 810 also reaches the top of the second bed board 4 under the drive of the two U-shaped blocks. The patient who needs to be operated on is then placed on the placement plate 810 and the patient is fixed to the placement plate 810 with straps. The self-locking motor 812 is started. The output end of the self-locking motor 812 will drive the transmission belt 814 connected to the pulley 813 to rotate. The transmission belt 814 will drive the rotating shaft 811 connected to another transmission belt 814 to rotate. The rotating shaft 811 will drive the placement plate 810 to rotate and drive the patient to rotate as a whole until the patient's back is completely facing upwards, thus completing the patient's rotation. When the placement plate 810 rotates the patient, it will not affect the patient's spine due to uneven force.Finally, rotating the operating block 914 causes the threaded cylinder 97 to rotate. The threaded cylinder 97 will cause the threaded rod 96 to extend and retract on the inner wall of the threaded cylinder 97. During the extension and retraction of the threaded rod 96, the trapezoidal block 95 will slide on the bottom of the inner wall of the sleeve 91. As the trapezoidal block 95 moves along the slider 92, it will cause the triangular block 94 to slide on the inner wall of the sleeve 91. The triangular block 94 will cause the auxiliary cylinder 98 to slide synchronously on the outer surface of the slide rod 99. At the same time, the triangular block 94 will cause the pressure block 10 to move vertically. Move the pressure block 10 until its top contacts the patient's chest cavity. Then rotate the nut 912 so that one side of the nut 912 contacts the rubber pad 913 on one side of the gear 910. This fixes the threaded cylinder 97 and the gear 910, preventing the gear 910 from rotating. This also fixes the slider 92 connected to the threaded cylinder 97 and the side plate 93, thereby fixing the position of the pressure block 10 and preventing it from shifting when the patient's chest cavity is placed on it. Then, the pressure block 10 can support the patient's spine. At this time, the elastic strap 822 is released from the restriction between the patient and the placement board 810, and the patient can be placed on the first bed board 3, the second bed board 4, and the third bed board 5. To facilitate the operation, the placement board 810 needs to be stored. Rotate the placement board 810 so that the first roller 816 disengages from the track 817 until the second roller 818 touches the ground. The length of the U-shaped frame 89 is slightly shorter than the width of the placement board 810. At this time, one side of the U-shaped frame 89... The side of the device abuts against one side of the auxiliary rod 87. The first rotating plate 819 and the second rotating plate 820, together with the auxiliary rod 87, support the placement plate 810. When the self-locking motor 812 is turned off, its output end automatically locks, thus fixing the placement plate 810 and the U-shaped frame 89 and preventing relative rotation between them. This facilitates stepping on the device by medical personnel and allows one side of the treatment device to be raised, making surgical operations easier for some medical staff.
