Referring to fig. 1 and 2, the resetting device of the present embodiment includes a bracket 100, a rotating frame 200, a first resetting rod 310 and a second resetting rod 320. The support 100 is used for stably supporting an operating table or other operating platform for performing an operation, and the rotating frame 200 can rotate in a rotating plane vertical to the operating table. Since the first and second restoring rods 310 and 320 are respectively installed at the rotating frame 200, the first and second restoring rods 310 and 320 can rotate along with the rotating frame 200. Meanwhile, the rotating frame 200 drives the first and second restoring rods 310 and 320 to rotate relative to the rotating frame 200, and the rotating directions of the first and second restoring rods 310 and 320 are always perpendicular to the rotating direction of the rotating frame 200.

Referring to fig. 3 to 5, the bracket 100 includes a horizontal fixing frame 110 and a horizontal driving frame 120. The horizontal fixing frame 110 includes an isosceles triangular plate 111, a first supporting rod 112, a first supporting rod 113 and a handle 114. The handle 114 is attached to the triangular plate 111, and the first support rod 112 and the first support rod 113 are respectively attached to both ends of the triangular plate 111 and are inclined downward of the triangular plate 111. The projections of the inclination directions of the first support rod 112 and the first support rod 113 on the horizontal plane pass through the center of the triangular flat plate 111. The horizontal driving frame 120 includes an L-shaped bracket 121 and a vertical rotating frame 122, the upper end of the L-shaped bracket 121 is parallel to the triangular plate 111 and is located below the triangular plate 111, and the lower end is vertically downward. The L-shaped bracket 121 is provided with a first brushless motor 510 directly below the triangular plate 111, and the axial direction of the motor shaft of the first brushless motor 510 is vertically upward and fixed to the center of the triangular plate 111. Meanwhile, the other end of the L-shaped bracket 121 opposite to the first brushless motor 510 is connected to a vertical rotating frame 122, and the vertical rotating frame 122 rotates in the vertical direction relative to the L-shaped bracket 121.

Meanwhile, the vertical rotating frame 122 is provided with a third supporting rod 123, and projections of the third supporting rod 123 in the horizontal plane pass through a motor shaft of the first brushless motor 510.

When external force is applied to rotate the vertical rotating frame 122, the vertical rotating frame 122 is at different inclination angles relative to the horizontal plane, and the third supporting rod 123 is gradually far away from or close to the projection point of the motor shaft of the first brushless motor 510 on the horizontal plane at the drop point of the operating table, so that the support 100 can be placed on the operating tables with different rules or can be spanned on two sides of the trunk of patients with different body types, and the medical staff can conveniently perform subsequent operation.

Referring to fig. 6 and 7, in the embodiment, the vertical rotating frame 122 is installed with a second brushless motor 520, and the second brushless motor 520 is fixed to the rotating frame 200, so that the rotating frame 200 can rotate perpendicular to the inclination angle of the vertical rotating frame 122. The turret 200 includes a U-shaped bracket 210, and a middle portion of the U-shaped bracket 210 is fixed to the second brushless motor 520. Meanwhile, a third brushless motor 530 and a fourth brushless motor 540 are installed at two opposite ends of the U-shaped bracket 210, respectively. The motor shaft of the third brushless motor 530 is coaxial with the motor shaft of the fourth brushless motor 540. The motor shaft of the third brushless motor 530 fixes the first restoring rod 310, and the motor shaft of the fourth brushless motor 540 fixes the second restoring rod 320.

Then the U-shaped bracket 210 can be rotated perpendicular to the angle of inclination of the vertical turret 122 when the second brushless motor 520 is rotated; meanwhile, the first restoring rod 310 can rotate relative to the U-shaped bracket 210 during the third brushless motor 530, and the rotation plane of the first restoring rod 310 and the rotation plane of the vertical rotating frame 122 are always kept parallel. When the fourth brushless motor 540 rotates, the second restoring rod 320 can rotate relative to the U-shaped bracket 210, and the rotation plane of the second restoring rod 320 is always parallel to the rotation plane of the vertical rotating frame 122.

The first and second restoring rods 310 and 320 can be electrically controlled to be shifted at a plurality of angles by the driving of the second, third and fourth brushless motors 520, 530 and 540, so that the medical staff can effectively and conveniently move the first and/or second restoring rods 310 and 320 to the necessary operation position to achieve the restoring operation to the vertebral body, and the first and second restoring rods 310 and 320 can be relatively tilted to adapt to the vertebral body tissue after different malformations and pathological excision.

Specifically, a first switch box 410 and a second switch box 420 are respectively mounted on the triangular plate 111 near the two ends of the first support rod 112 and the second support rod. The upward and downward directions of the first switch box 410 and the second switch box 420 can control the forward and reverse rotation of the third brushless motor 530 and the fourth brushless motor 540, respectively. The left and right decibels of the first switch box 410 can control the forward and reverse rotation of the first brushless motor 510, and the left and right decibels of the second switch box 420 can control the forward and reverse rotation of the second brushless motor 520.

Meanwhile, fig. 5 shows that a control board 1222 implementing control of the first to fourth brushless motors 510 to 540 and control of the first and second key boxes in the present embodiment is installed at the vertical rotary frame 122. The vertical turret 122 includes a hinge connection block 1211, a vertical channel 1221, and a vertical channel plate. The upper end of the hinge connection block 1211 is fixed to the lower end of the L-shaped bracket 121, and the lower end thereof is fixed to the vertical channel 1221. The second driving motor and the control board 1222 are respectively fixed in the vertical channel steel 1221; the vertical frid cooperation is in vertical channel-section steel 1221 for the realization is to the covering of circuit board, and a plurality of heat dissipation through-holes have been seted up to vertical frid, are favorable to the temperature of first brushless motor 510 and control panel 1222 to scatter and disappear. The third support bar 123 is mounted on the vertical channel 1221.

In this embodiment, the U-shaped bracket 210 is formed by welding a middle channel 211, a left channel 212, and a right channel 213. The middle channel steel 211 is fixed with a motor shaft of the second brushless motor 520. The electric wire is connected to the third brushless motor 530 after passing through the middle channel 211 and the left channel 212 in sequence, and is connected to the fourth brushless motor 540 after passing through the right channel 213 and the right channel 213 in sequence. Meanwhile, the middle channel steel 211 is matched with a middle slot cover, the left channel steel 212 is matched with a left slot cover, and the right channel steel 213 is matched with a right slot cover.
