Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4This utility model provides a technical solution: a surgical dislocation device for lumbar spine patients, including a first clamp 1 and a second clamp 2. The first clamp 1 and the second clamp 2 constitute a dislocation clamp, which dislocates the lumbar spine to facilitate surgical treatment of patients with reduced intervertebral space. The first clamp 1 includes a first handle 3 and a first dislocation rod 4, which are connected and fixed by a first connecting plate 5. The second clamp 2 includes a second handle 6 and a second support rod 7, which are connected and fixed by a second connecting plate 8. The first connecting plate 5 and the second connecting plate 8 are rotatably connected by a positioning shaft 9.

[0019] The first handle 3 and the first spreading rod 4 are located on the same side of the first connecting plate 5, and the second handle 6 and the second support rod 7 are located on the same side of the second connecting plate 8. A rotation space is reserved between the first handle 3 and the second handle 6. When in use, medical staff apply force to the first handle 3 and the second handle 6 to make them rotate around the positioning shaft 9 and move closer to each other in the rotation space. When the first handle 3 and the second handle 6 move closer to each other, the first spreading rod 4 and the second support rod 7 separate. The separated first spreading rod 4 and the second support rod 7 open up the patient's lumbar spine, which facilitates surgery on patients with lumbar vertebral slippage.

[0020] A limiting component is provided between the first supporting rod 4 and the second supporting rod 7. This limiting component is used for support and positioning after the first supporting rod 4 and the second supporting rod 7 are separated. A mounting groove 10 is provided on the upper side of the second supporting rod 7. The limiting component includes a positioning plate 12 rotatably installed within the mounting groove 10. The mounting groove 10 is used to store the positioning plate 12, facilitating its installation and use. A mounting base 11 is fixed to the bottom of the mounting groove 10. One end of the positioning plate 12 is rotatably installed within the mounting base 11 via a pivot. Several positioning grooves 14 are provided on the side of the first supporting rod 4 near the mounting groove 10, and these positioning grooves 14 are arranged along the length of the first supporting rod 4. After the first supporting rod 4 and the second supporting rod 7 are separated... The rotatable positioning plate 12 is removed from the mounting slot 10 and locked in the positioning slot 14 on the side of the first support rod 4. The positioning slot 14 limits the positioning plate 12. The positioning plate 12 is used to limit the separation of the first support rod 4 and the second support rod 7, which facilitates the use of this support device. The end of the positioning plate 12 away from the mounting base 11 is set at an angle, which makes it easy to lock the positioning plate 12 in the positioning slot 14 for positioning. The positioning plate 12 can be locked in the positioning slot 14 at a suitable position on the side of the first support rod 4 according to the separation angle of the first support rod 4 and the second support rod 7. After the operation, the positioning plate 12 is removed from the positioning slot 14 to release the positioning of the lumbar spine by this support device.

[0021] The second support rod 7 has a mounting hole on its side that communicates with the mounting groove 10. A magnet 13 is installed in the mounting hole. The positioning plate 12 is made of magnetic material. When the positioning plate 12 is stored in the mounting groove 10, the magnet 13 attracts and positions the positioning plate 12.

[0022] Positioning parts 15 are provided on the lower side of the first spreading rod 4 and the lower side of the second support rod 7. The positioning parts 15 are equipped with friction elements. When the lumbar vertebrae are spread open, the positioning parts 15 contact the lumbar vertebrae on both sides of the gap. The friction elements provided in the positioning parts 15 increase the friction between the positioning parts 15 and the lumbar vertebrae, improving the stability during positioning. The friction elements are preferably protective pads. The setting of protective pads can also reduce the damage of the positioning parts 15 to the lumbar vertebrae, making it easier to perform surgical treatment on patients with lumbar vertebral slippage.

[0023] The bottom of the first support rod 4 and the bottom of the second support rod 7 are both set at an angle, such as Figure 1 or Figure 2 As shown, the inclined surfaces at the bottom of the first support rod 4 and the bottom of the second support rod 7 facilitate placing the support device within the lumbar intervertebral space to support the lumbar spine.

[0024] This surgical dislocation device for lumbar spine patients opens the lumbar spine by prying it open, which can effectively avoid secondary damage to the lumbar spine caused by rotating the reamer. After the lumbar spine is opened by this dislocation device, it can be positioned by the limiting component, which makes it easy for the dislocation device to keep the lumbar spine open for a long time, and facilitates surgical treatment for patients with lumbar vertebral slippage.

[0025] The parts not disclosed in this utility model are all prior art, and their specific structures, materials, and working principles will not be described in detail. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
