Usually, when performing vertebral shaping surgery, the tray used is just an ordinary surgical instrument tray. When using an ordinary surgical instrument tray to place vertebral shaping tools, since the ordinary surgical instrument tray cannot stably place the bone needles and syringes in the vertebral shaping tools, the vertebral shaping tools are easily shaken by external forces when placed in the ordinary surgical instrument tray, causing friction damage.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: comprising a bone needle, a syringe, a tray, a support column and a placement box;

[0006] The top end of the support column is fixedly connected to a U-shaped frame, and pin holes are opened on both side walls of the U-shaped frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] When the push plate moves linearly inward, the utility model pushes the sheet-like rubber pad to clamp and fix the outer curved surfaces of both ends of the bone needle. At the same time, when the bone needle needs to be removed, the bone needle can be taken out from the inner side of the sheet-like rubber pad by pulling the bone needle upward, thereby achieving the goal of clamping and fixing the bone needle and facilitating the removal of the bone needle, avoiding the problem of the bone needle being placed inside the tray and being easily shaken and caused by wear;

[0016] The utility model also clamps and fixes the syringe through the arc-shaped rubber pad. When the syringe needs to be removed, the support screw is rotated. When the support screw rotates, the support screw will move back and forth in a straight line due to the force of the threaded connection with the middle part of the rear side of the placement box. When the support screw moves back and forth in a straight line, it will drive the movable clamping block to move backward in a straight line. When the movable clamping block moves backward in a straight line, the clamping of the syringe can be released, thereby achieving the overall clamping and fixing of the bone needle and the syringe, and facilitating the removal of the bone needle and the syringe.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-3 , the utility model provides a technical solution: including a bone needle 1, a syringe 2, a plate 3, a support column 4 and a placement box 5;

[0023] The support column 4 is welded to the front side of the bottom end of the disk body 3. There are eight support columns 4, and each two support columns 4 form a group. The four groups of support columns 4 are symmetrically distributed on the front side of the bottom end of the disk body 3. A U-shaped frame 6 is welded on the top of the support column 4. Pin holes 7 are opened on both sides of the U-shaped frame 6. The pin holes 7 are symmetrically distributed on both sides of the U-shaped frame 6. Pin columns 8 are inserted into the inner wall of the pin hole 7. The outer end of the pin column 8 is bonded to a limit plate 9. The inner circumference of the limit plate 9 is bonded with a spring 10, and the elastic The inner end of the spring 10 is bonded to the outer walls on both sides of the U-shaped frame 6. The spring 10 is in a compressed state, so that when the spring 10 is in a compressed state, the spring 10 will drive the limit plate 9 to move inward due to the elastic potential energy generated by its own compression deformation. When the limit plate 9 moves inward, it will push the pin 8 to move inward along the inner wall of the pin hole 7. A push plate 11 is bonded to the top end of the inner side of the pin 8, and a limiting groove 12 is provided at the lower end of the push plate 11. The inner wall of the limiting groove 12 is fitted and movably connected to the U-shaped frame 6. On both sides of the bottom surface, when the pin 8 moves inward, it will drive the push plate 11 to move inward. When the push plate 11 moves inward, it will drive the inner wall of the limiting groove 12 to move linearly inward along both sides of the inner bottom surface of the U-shaped frame 6. Therefore, through the limiting groove 12, the push plate 11 can be limited to move linearly inward. A sheet rubber pad 13 is bonded to the inner side of the push plate 11, and the inner side of the upper end of the sheet rubber pad 13 is provided with a rounded corner. The outer curved surfaces at both ends of the bone needle 1 are movably clamped and connected. The inner side of the sheet rubber pad 13 is configured so that when the push plate 11 moves linearly inward, the sheet rubber pad 13 is pushed to clamp and fix the outer curved surfaces at both ends of the bone needle 1. At the same time, when the bone needle 1 needs to be removed, the bone needle 1 can be taken out from the inner side of the sheet rubber pad 13 by pulling it upward. This achieves the goal of clamping and fixing the bone needle 1 while facilitating its removal, thus avoiding the problem of the bone needle 1 being easily shaken and worn when placed inside the tray 3.

[0024] The inner bottom surface of the placement box 5 is bonded to the rear side of the inner bottom surface of the disk body 3, and a fixed clamping block 14 is welded to the middle support of the front side of the placement box 5. A support screw 15 is threadedly connected to the middle of the rear side of the placement box 5, and the support screw 15 passes through the middle of the rear side of the disk body 3. A knob is bonded to the rear top of the support screw 15, and the front top of the support screw 15 is rotatably connected to a movable clamping block 16 through a rotating shaft, and an arc-shaped clamping opening is provided on the inner side of the fixed clamping block 14 and the movable clamping block 16. Limiting columns 17 are bonded to the two ends of the rear side of the movable clamping block 16, and there are two limiting columns 17, which are symmetrically distributed at the two ends of the rear side of the movable clamping block 16, and the rear end of the limiting column 17 passes through the rear side of the disk body 3, so that the limiting column 17 plays a limiting role in the forward and backward linear movement of the movable clamping block 16. The inner arc surfaces of the fixed clamping block 14 and the movable clamping block 16 are bonded with an arc-shaped rubber pad 18, and the syringe 2 is movably clamped and connected to the inner surface of the arc-shaped rubber pad 18, so that the syringe 2 is clamped and fixed by the arc-shaped rubber pad 18. At the same time, when the syringe 2 needs to be removed, the support screw 15 is rotated. When the support screw 15 rotates, the support screw 15 will move back and forth due to the force of the threaded connection with the middle part of the rear side of the placement box 5. When the support screw 15 moves back and forth, it will drive the movable clamping block 16 to move backward in a straight line. When the movable clamping block 16 moves backward in a straight line, the clamping of the syringe 2 can be released, thereby achieving the overall clamping and fixing of the bone needle 1 and the syringe 2 while facilitating the removal of the bone needle 1 and the syringe 2.
