DETAILED DESCRIPTION

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-4 , the present invention discloses a spinal reduction device for spinal dislocation surgery, including two support plates 1. Fixed rods 201 are fixedly arranged at the front and rear between the two support plates 1. Connecting blocks 202 are movably arranged on both sides of the outer part of the fixed rod 201. Chutes are formed on the opposite sides of the connecting blocks 202, and slide rods 203 are fixedly arranged in the chutes. A connecting plate 204 is movably arranged on the outer part of the slide rod 203. A connecting rod 205 is fixedly arranged at the bottom of the connecting plate 204. One end of the connecting rod 205 is fixedly provided with a mounting block 301;

[0025] One side of the mounting block 301 is fixedly provided with a fixed block 304. An installation groove is formed inside the fixed block 304, and an annular clamping plate 305 is movably arranged in the installation groove. The connection relationship between the annular clamping plate 305 and the fixed block 304 is a sliding connection. A limiting rod 306 is fixedly arranged on the inner wall of the annular clamping plate 305. A return spring 307 is movably arranged on the outer part of the limiting rod 306. The connection relationship between the return spring 307 and the limiting rod 306 is a sleeved connection. A groove is formed at the bottom of the mounting block 301, and a bidirectional lead screw 302 is movably arranged in the groove. One end of the bidirectional lead screw 302 is fixedly provided with a knob 303. A limiting groove 405 adapted to the limiting rod 306 is formed on the outer wall of the knob 303. The connection relationship between the limiting groove 405 and the limiting rod 306 is a movable insertion. Moving blocks 401 are movably arranged on both sides of the outer wall of the bidirectional lead screw 302. Fixed grooves are formed at the bottoms of the opposite sides of the moving blocks 401, and connectors 402 are movably arranged in the fixed grooves. A fixing bolt 403 is movably arranged inside the connector 402. The connection relationship between the fixing bolt 403 and the connector 402 is a movable insertion. Reset clamping blocks 404 are fixedly arranged on the opposite sides of the connector 402.

[0026] Specifically, a pull ring 308 is fixedly arranged at one end of the limiting rod 306.

[0027] In this embodiment, by setting the pull ring 308, medical staff can release the limit on the knob 303 by pulling the pull ring 308, which is simple and convenient to operate and reduces the work burden of medical staff.

[0028] Specifically, the limiting grooves 405 are annularly distributed along the outer wall of the knob 303.

[0029] In this implementation scheme, by setting the limiting grooves 405, the multiple uniformly distributed limiting grooves 405 enable the limiting rod 306 to limit the knob 303 after the knob 303 rotates by any angle.

[0030] Specifically, rubber pads are fixedly arranged on the opposite sides of the reset clamping blocks 404.

[0031] In this implementation scheme, by setting the reset clamping blocks 404, when the reset clamping blocks 404 move towards each other to clamp the patient's spine, the rubber pads can improve the comfort of the patient and relieve the pain of the patient.

[0032] Specifically, the top of the connecting plate 204 is fixedly connected to the telescopic end of the air cylinder 406.

[0033] In this implementation scheme, by setting the connecting plate 204 and the air cylinder 406, the telescopic end of the air cylinder 406 drives the connecting plate 204 to move, thereby adjusting the height of the connecting plate 204.

[0034] Specifically, a slider 407 is fixedly arranged on the top of the air cylinder 406.

[0035] In this implementation scheme, by setting the air cylinder 406 and the slider 407, the air cylinder 406 moves along with the movement of the slider 407, causing the position of the reset clamping block 404 to move.

[0036] Specifically, a screw rod 408 is movably arranged inside the slider 407.

[0037] In this implementation scheme, by setting the slider 407 and the screw rod 408, when the screw rod 408 rotates, the slider 407 moves accordingly. At the same time, the guide rod guides and limits the slider 407, and the slider 407 moves horizontally as a result.

[0038] Specifically, one end of the screw rod 408 is fixedly connected to the output shaft of the motor 409.

[0039] In this implementation scheme, by setting the screw rod 408 and the motor 409, the motor 409 can accurately control the rotation speed and rotation direction of the screw rod 408, improving the accuracy of the surgical operation and further enhancing the reset effect.

[0040] During use, first fix the spinal corrector on the edge of the operating table, then start the cylinder 406, and its telescopic end drives the connecting plate 204 to move vertically downward under the cooperation of the sliding rod 203, and then position the position of the patient to be fixed through the positioning block. Start the motor 409, and the screw rod 408 rotates with the rotation of the output shaft of the motor 409. The slider 407 thus moves horizontally until the position of the reset clamping block 404 is adjusted directly above the patient's surgical incision. Start the cylinder 406, and the connecting plate 204 continues to move downward in the groove of the connecting block 202. When the positioning block presses the spring, pull up the pull ring 308, and the limiting rod 306 drives the annular clamping plate 305 to move upward. At the same time, the reset spring 307 is compressed. When the limiting rod 306 moves out of the limiting groove 405, rotate the knob 303, and the bidirectional lead screw 302 rotates accordingly, so that the moving block 401 and the reset clamping block 404 move towards or away from each other until the reset clamping block 404 firmly clamps the patient's spine, thereby realizing the reduction of the patient's vertebral body. After the adjustment is completed, release the pull ring 308. Under the elastic force of the reset spring 307, the annular clamping plate 305 moves in the installation groove, and the limiting rod 306 is thus inserted into the limiting groove 405, thereby achieving the purpose of quickly limiting the knob 303 and avoiding affecting the reduction effect due to accidental rotation of the knob 303.

[0041] When it is necessary to clean and disinfect the reset clamping block 404, loosen the fixing bolt 403. After releasing the limit on the reset clamping block 404, the reset clamping block 404 can be removed for cleaning and disinfection. After the operation is completed, insert the connecting piece 402 into the fixing groove and tighten the fixing bolt 403, thereby fixing the reset clamping block 404 for the subsequent use of the patient and reducing the risk of cross-infection.

[0042] In summary, for the spinal reduction device used in spinal dislocation surgery, when adjusting the distance between the reset clamping blocks 404 by setting the fixing block 304, the annular clamping plate 305, the limiting rod 306, the reset spring 307 and the pull ring 308, first pull the pull ring 308 upward, the limiting rod 306 drives the annular clamping plate 305 to move upward, and the reset spring 307 is compressed. When the limiting rod 306 moves out of the limiting groove 405, rotate the knob 303 to make the reset clamping blocks 404 move towards or away from each other. After the adjustment is completed, release the pull ring 308. Under the elastic force of the reset spring 307, the annular clamping plate 305 moves in the installation groove, and the limiting rod 306 is inserted into the limiting groove 405 accordingly, thereby realizing the rapid limiting of the knob 303. The operation is convenient, which provides convenience for medical staff and reduces the risk that the knob 303 accidentally rotates during the operation and reduces the accuracy of vertebral body fixation and reduction, thus maintaining the safety of the surgical operation, improving the surgical effect and the comfort of the patient. By setting the connecting piece 402 and the fixing bolt 403, after screwing the fixing bolt 403, pull out the reset clamping block 404 until the connecting piece 402 disengages from the fixing groove. At this time, the reset clamping block 404 can be removed, enabling medical staff to thoroughly clean and disinfect it after the operation, so as to facilitate the recycling of the device, effectively reducing the risk of cross-infection and prolonging the service life of the reset clamping block 404.
