Technical Field

[0001] The utility model belongs to the technical field of spinal surgery, and in particular relates to a spinal trauma surgery fixation device. Background Art

[0002] Spinal surgery is a type of surgery that treats spinal problems. It is usually used to treat spinal deformities, spinal fractures, spinal tumors, etc. During the operation, the doctor will expose the spine by cutting the skin and muscle tissue, and then perform corresponding treatment and repair. At this time, a fixation component is needed to fix the skin and muscle tissue, which will then make it easier for the doctor to treat spinal trauma.

[0003] However, the above device still has the following problems during implementation:

The bottom of the lifting rod 42 passes through the L-shaped rod 43 and is fixedly connected to the lifting shell 5. The opposite sides of the two L-shaped rods 43 are provided with moving holes 10.

[0030] The above scheme is adopted: by setting the lifting slot 9 and the moving hole 10, when it is necessary to control the lifting rod 42 to move up and down, the lifting shell 5 is pulled up to drive the lifting rod 42 to rise. At this time, the lifting slot 9 and the lifting shell 5 can position the upper and lower positions of the lifting rod 42.

[0031] refer to Figure 5The positioning assembly 6 includes a T-shaped plate 61, and the front and rear sides of the T-shaped plate 61 close to the moving hole 10 are fixedly connected to the first spring 62. The side of the T-shaped plate 61 close to the moving hole 10 passes through the lifting shell 5 and is fixedly connected to the docking block 63.

[0032] The above solution is adopted: by setting the positioning component 6, when the position of the lifting shell 5 needs to be fixed, the pressure on the T-shaped plate 61 by the first spring 62 will prevent the T-shaped plate 61 from moving easily, and the docking block 63 fixed to the T-shaped plate 61 will not be detached.

The inner cavity of the fixed shell 3 is movably connected with an extrusion block 13 used in conjunction with the pulley 12, and the opposite sides of the two pulleys 12 are in contact with the extrusion block 13.

[0036] By adopting the above solution: by setting the pulley 12 and the extrusion block 13, when the two L-shaped rods 43 need to move simultaneously, the extrusion block 13 rises to squeeze the pulley 12, so that the inclined surface on the extrusion block 13 drives the two L-shaped rods 43 away from each other.

[0037] refer to Figure 3 A travel tube 14 is sleeved on the surface of the L-shaped rod 43 , and a side of the travel tube 14 close to the fixed shell 3 is fixedly connected to the fixed shell 3 . A travel ring 15 is fixedly connected to the surface of the L-shaped rod 43 .

[0038] By adopting the above solution, the stroke tube 14 and the stroke ring 15 are provided, and when the L-shaped rod 43 moves, the stroke tube 14 and the stroke ring 15 can control the moving position of the L-shaped rod 43, so that the L-shaped rod 43 will not separate from the fixed shell 3 when moving.

[0039] refer to Figure 3The lifting assembly 7 includes a threaded hole 71, which is provided at the top of the extrusion block 13. The inner cavity of the threaded hole 71 is threadedly connected with a threaded rod 72. The bottom of the threaded rod 72 passes through the fixed shell 3 and extends to the outside of the fixed shell 3. The surface of the threaded rod 72 is fixedly connected with a rotating ring 73. A rotating groove 74 for use with the rotating ring 73 is provided on one side of the fixed shell 3 close to the rotating ring 73.

[0041] refer to Figure 3 The second springs 16 are fixedly connected to the opposite sides of the two travel rings 15 , and the opposite sides of the two second springs 16 are fixedly connected to the travel tube 14 .

[0042] By adopting the above solution: by setting the second spring 16, when the extrusion block 13 moves down to the original position, the second spring 16 will undergo elastic deformation to drive the L-shaped rod 43 back to the original position, so that the L-shaped rod 43 can be automatically driven back to the original position.

[0043] The working principle of this utility model:

[0044] During use, when a spinal trauma operation is required for a patient, the patient is laid flat on the operating table 2, and then the doctor cuts open the patient's back. When the grasping plate 41 is required to fix the muscle tissue, the threaded rod 72 is rotated to drive the squeezing block 13 threadedly connected thereto to rise, and the squeezing block 13 squeezes the pulley 12 to drive the two L-shaped rods 43 away from each other, and the L-shaped rod 43 drives the lifting rod 42 away from each other. After the lifting rod 42 moves and drives the grasping plate 41 to a suitable position, the pull ring on the docking block 63 is pulled to drive the docking block 63 to disengage from the docking groove 11, and the movement of the docking block 63 drives the T-shaped plate 61 to move and squeeze the first elastic Spring 62, when the docking block 63 moves to the appropriate position, the pull ring is pulled down to drive the lifting shell 5 to descend in the lifting slot 9, and the movement of the lifting shell 5 will drive the lifting rod 42 to descend, and the descent of the lifting rod 42 will drive the grab plate 41 to enter the muscle tissue of the opening, and then the pull ring is released, the first spring 62 undergoes elastic deformation and the T-shaped plate 61 returns to its original position, and the movement of the T-shaped plate 61 will drive the docking block 63 to be inserted into the docking slot 11, so that the position of the lifting rod 42 can be fixed, and then the threaded rod 72 can be rotated a few times. At this time, the extrusion block 13 will also rise, so that the L-shaped rod 43 will drive the grab plate 41 to fix the muscle tissue on both sides.

[0045] In summary: the spinal trauma surgical fixation device, through the arrangement of the fixing shell 3, the muscle fixing component 4, the grasping plate 41, the lifting rod 42, the L-shaped rod 43, the lifting shell 5, the positioning component 6 and the lifting component 7, the lifting rod 42 descends to drive the grasping plate 41 into the opened muscle tissue, and then the threaded rod 72 can be rotated several times. At this time, the extrusion block 13 will also rise, so that the L-shaped rod 43 will drive the grasping plate 41 to fix the muscle tissue on both sides, which solves the problem that during spinal trauma surgery, two nursing doctors use two grasping plates 41 to fix the skin and muscle tissue. Such a process will last for a long time, which will be more labor-intensive. If the hand slips suddenly, the operation may be terminated.
