[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] like Figure 1 As shown, an operating table for orthopedic vertebroplasty includes an operating bed 1. Guide support mechanisms 4 are installed on both sides of the operating bed 1. A movable support frame 2 is fixed on the top of the two guide support mechanisms 4. The movable support frame 2 is a U-shaped structure, and an imaging device 3 is detachably installed at the bottom middle of the movable support frame 2. The upper surface of the operating bed 1 is provided with a mounting slot 6, and a support adjustment mechanism 5 is installed on the inner side of the mounting slot 6. The patient's spinal imaging is performed by the imaging device 3, which facilitates medical staff to perform spinal puncture and bone cement injection on the patient.

[0029] like Figures 1 to 3 As shown, the support adjustment mechanism 5 includes a regulating motor 502, and the output shaft end of the regulating motor 502 is fixed with a regulating double-headed screw rod 503, and the outer sides of the two ends of the regulating double-headed screw rod 503 are sleeved with regulating slide plates 504, and the two regulating slide plates 504 are driven by the regulating double-headed screw rod 503 through threads, and two elastic support rods 505 are fixed between the two regulating slide plates 504, and the two elastic support rods 505 are located on both sides of the regulating double-headed screw rod 503, and a plurality of regulating support arc plates 506 are fixed on the outer sides of the two elastic support rods 505, and the regulating support arc plates 506 are moved along the elastic The support rods 505 are distributed in a linear array in the length direction, and the elastic support rods 505 are covered with rubber isolation pads 501. The four sides of the rubber isolation pads 501 are fixed to the operating bed 1 by strong glue. The distance between the two adjustment slides 504 is adjusted by adjusting the motor 502 and the double-headed screw 503, so that the adjustment slides 504 squeeze or release the elastic support rods 505, changing the curvature of the elastic support rods 505, thereby changing the height difference between each adjustment support arc plate 506, and thus changing the bending curvature of the rubber isolation pad 501.

[0030] A ventilation groove is provided under the regulating motor 502, and the bottom opening of the ventilation groove is flush with the bottom surface of the operating bed 1. The two ends of the regulating double-headed screw rod 503 are rotatably connected to the operating bed 1 through roller bearings. The ventilation groove is used to dissipate heat for the regulating motor 502 in operation, so as to avoid damage or malfunction of the regulating motor 502 due to untimely heat dissipation.

[0031] The regulating support arc plate 506 includes two vertical support plates 5061, and the bottom ends of the two vertical support plates 5061 are penetrated by mounting holes 5062. The elastic support rod 505 passes through the middle of the mounting hole 5062 and is fixed to the vertical support plate 5061. The tops of the two vertical support plates 5061 are fixed with elastic support plates 5063, and an anti-deviation plate 5064 is fixed between the two elastic support plates 5063. The middle part of the anti-deviation plate 5064 is arc-shaped and concave downward, and a buffer pad 507 is installed on the inner side of the anti-deviation plate 5064. The patient's torso is positioned by the anti-deviation plate 5064 to ensure that the patient's torso squeezes the buffer pad 507 and sinks into the inner side of the anti-deviation plate 5064 after lying down, so that the patient's torso will not deviate left and right during the operation.

[0032] like Figure 1 、 Figures 4 to 7 As shown, the guide support mechanism 4 includes a guide support rod 401, the end of the guide support rod 401 is fixed to the operating bed 1, and guide grooves 402 are provided on both sides of the guide support rod 401. A sliding support seat 403 is slidably installed on the upper surface of the guide support rod 401, and the end of the mobile support frame 2 is fixed to the sliding support seat 403. The bottom of the sliding support seat 403 is detachably installed with an anti-slip bottom plate 404. The position of the mobile support frame 2 is adjusted by the sliding support seat 403, thereby adjusting the position of the angiography equipment 3 according to the patient's spinal surgery position.

[0033] Two symmetrically distributed L-shaped plug-in strips are fixed to the upper surface of the anti-slip base plate 404, and two anti-slip plug-in grooves 406 are provided at one end of the sliding support seat 403. The L-shaped plug-in grooves are slidably plugged into the inner side of the anti-slip plug-in grooves 406, and the upper surface of the anti-slip base plate 404 contacts the bottom surface of the guide support rod 401. The anti-slip base plate 404 is clamped to the bottom of the sliding support seat 403 to limit the position of the sliding support seat 403, so that the sliding support seat 403 will not fall off while sliding along the outer side of the guide support rod 401.

[0034] A limiting friction plate 407 is installed on the inner side of the sliding support seat 403. The limiting friction plate 407 is bent in an L shape and is located on the inner side of the guide slide groove 402. One side edge of the limiting friction plate 407 is slidably inserted into the inner side of the sliding support seat 403. The surface of the limiting friction plate 407 that fits the inner wall of the guide slide groove 402 is provided with a rough rubber gasket. The limiting friction plate 407 is squeezed and rubbed with the guide support rod 401, thereby increasing the friction resistance between the sliding support seat 403 and the guide support rod 401, ensuring that the mobile support frame 2 and the imaging equipment 3 will not be offset during the operation.

[0035] A rotating groove 409 is provided on the surface of the sliding support seat 403 facing the outside of the operating bed 1, and an adjusting handle bar 405 is inserted into the inner side of the rotating groove 409. One end of the adjusting handle bar 405 is fan-shaped and contacts the limiting friction plate 407. A positioning shaft pin 408 is rotatably installed inside the rotating groove 409, and the positioning shaft pin 408 passes through the adjusting handle bar 405. By rotating the adjusting handle bar 405, the end of the fan-shaped structure of the adjusting handle bar 405 squeezes or releases the limiting friction plate 407, thereby adjusting the friction resistance between the limiting friction plate 407 and the guide support rod 401, thereby realizing the movement or immovability of the sliding support seat 403.

[0036] Working principle: When performing vertebroplasty on a patient, the patient is first placed on the upper surface of the rubber isolation pad 501. At this time, the power supply of the regulating motor 502 is turned on and started. After the regulating motor 502 is energized, it drives the regulating double-headed screw 503 to rotate. The regulating double-headed screw 503 causes the two regulating slides 504 to move relative to each other through thread transmission. When the two regulating slides 504 move relative to each other, they squeeze the elastic support rod 505, causing the elastic support rod 505 to bend upward. The bent elastic support rod 505 drives each regulating support arc plate 506 to be lifted in height, so that the regulating support arc plate 506 lifts the rubber isolation pad 501 in an arc shape.

[0037] After the rubber isolation pad 501 is positioned in an arc shape, the patient is lifted upward from under the patient's body. At this time, the patient relaxes his whole body. The medical staff controls the operation of the control motor 502 according to the degree of extension of the patient's spine. After the patient's spine is fully extended, the power supply of the control motor 502 is cut off. At this time, the control support arc plate 506 stops rising. At the same time, the patient's body presses the cushion pad 507 and sinks into the inner side of the anti-deviating plate 5064. Then, the patient lying on the surface of the rubber isolation pad 501 is anesthetized.

[0038] After the patient is anesthetized, the medical staff pushes the movable support frame 2 and the sliding support seat 403 to move, so that the sliding support seat 403 drives the anti-slip bottom plate 404 to slide on the outside of the guide support rod 401 until the angiography equipment 3 moves to the spinal bone position where the patient needs surgery. At this time, the medical staff rotates the rotating groove 409, so that the adjusting handle 405 that was originally tilted with the sliding support seat 403 is rotated to be perpendicular to the sliding support seat 403. The rotated adjusting handle 405 squeezes the limiting friction plate 407 toward the guide support rod 401. The limiting friction plate 407 squeezed with the guide support rod 401 increases the friction resistance between the sliding support seat 403 and the guide support rod 401, ensuring that the sliding support seat 403 and the movable support frame 2 will not move.

[0039] Finally, the medical staff performs surgical angiography on the patient through the angiography equipment 3. The doctor performs a spinal puncture on the patient based on the angiography results. After the spinal puncture, bone cement is poured into the patient's spine to complete the spinal vertebroplasty. By changing the curvature of the elastic support rod 505, the height difference between each regulating support arc plate 506 is changed, thereby changing the curvature of the rubber isolation pad 501, thereby adjusting the degree of expansion of the patient's back according to the body shape of different patients, so that the patient's spine is fully expanded.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
