Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a simple orthopedic repositioning device. Background Technology

[0002] In orthopedic surgery, when treating fractures in the injured limbs, it is necessary to first reposition and traction the fractured bones to provide good preconditions for the next step of the surgery. Currently, when performing surgery on fractured bones, external fixation brackets or internal fixation plates are used to fix and bandage the aligned bones so that the fractured bones can grow and heal normally.

[0003] Existing orthopedic reduction devices can only traction and splice bones in the same axis, and cannot traction in multiple directions simultaneously. Generally, multiple reduction devices need to be used to achieve the effect of traction and reduction of bones, which is inconvenient and manual operation is always unstable, causing inconvenience to the doctor's surgical operation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a simplified orthopedic repositioning device to solve the problem mentioned in the background art that it cannot simultaneously apply traction in multiple directions, and that it generally requires the use of multiple repositioning devices to achieve the effect of traction and repositioning of bones, which is inconvenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a simple orthopedic reduction device, comprising a fixing rod, two double-rod fixators movably sleeved on the outer wall of the fixing rod, each double-rod fixator having a first bolt threaded inside, a ball head rotatably connected inside, a second bolt threaded inside, a connector movably connected to the outer wall of each double-rod fixator, two first bone screws threaded inside, a pressure cap threaded inside, a handle threaded inside, a slider slidably connected to the outer wall of the fixing rod, a third bolt threaded inside, a second bone screw threaded inside, a hook block slidably connected to the outer wall of the fixing rod, a locking block slidably connected inside the hook block, and a third bolt penetrating through the locking block.

[0006] Preferably, the outer wall of the third bolt is threadedly connected to the inner thread of the hook block, and the outer wall of the locking block is slidably connected to the outer wall of the fixing rod.

[0007] Preferably, both connectors have threaded rods internally connected to them, and the outer walls of the threaded rods are respectively connected to the internal threads of the two ball heads.

[0008] Preferably, both connectors have multiple threaded holes inside, and the spacing between the multiple threaded holes is equal.

[0009] Preferably, both connectors are provided with anti-slip grooves on the side near the double rod retainer, and both ball heads are provided with limiting grooves at their bottom ends, with the limiting grooves and anti-slip grooves being arranged in a corresponding manner.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This simple orthopedic reduction device works by inserting the first bone screw into both sides of the fractured bone. Moving the handle moves the double-rod fixator, causing the connector and the second bone screw to move, thus splicing the bones together. After splicing, turning the first and second bolts fixes the double-rod fixator to the outside of the fixation rod. Tightening the second bolt clamps the ball head, achieving the effect of splicing the bones. The ball head can be rotated and adjusted at a certain angle within the double-rod fixator, achieving multi-directional adjustment and multi-angle fixation of the bones. This solves the problem of existing reduction devices being inconvenient because they cannot simultaneously apply traction in multiple directions.

[0012] 2. This simple orthopedic reduction device can move on the outside of the fixing rod via a slider and hook, and can be adjusted according to the location of the bone fracture, increasing the practicality of the device. Attached Figure Description

[0018] 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.

[0019] Example:

[0020] Please refer to the following: Figure 1-4 ,

[0021] A simple orthopedic reduction device includes a fixation rod 1. Two double-rod fixators 2 are movably sleeved on the outer wall of the fixation rod 1. The inner parts of the two double-rod fixators 2 are threaded with first bolts 3. The inner parts of the two double-rod fixators 2 are rotatably connected with ball heads 4. The inner parts of the two double-rod fixators 2 are threaded with second bolts 5. The outer walls of the two double-rod fixators 2 are movably connected with connectors 6. The inner parts of the two connectors 6 are threaded with two first bone screws 7. The inner parts of the two ball heads 4 are threaded with pressure caps 8. The inner parts of the two pressure caps 8 are threaded with handles 9. The outer wall of the fixation rod 1 is slidably connected with a slider 10. The inner parts of the slider 10 are threaded with third bolts 11. The inner parts of the slider 10 are threaded with second bone screws 12. The outer wall of the fixation rod 1 is slidably connected with a hook block 13. The inner parts of the hook block 13 are slidably connected with a locking block 14. The inner parts of the locking block 14 are through-entered with the third bolt 11.

[0022] Specifically, when using this device, firstly, the location of the patient's bone fracture is determined. Then, the first bone nail 7 is driven into both sides of the fractured bone. Next, the first bolt 3 and the second bolt 5 are loosened. Then, the connector 6 is installed on the ball head 4. Then, the handle 9 is moved, which will drive the double rod fixator 2 to move, causing the connector 6 and the second bone nail 12 to move. Then, the bones are spliced ​​together. After the splicing is completed, the first bolt 3 and the second bolt 5 are twisted. The first bolt 3 works with the double rod fixator 2 to fix the double rod fixator 2 to the outside of the fixation rod 1. After the second bolt 5 is tightened, the ball head 4 can be clamped, so that the ball head 4 is restricted and will not move easily. This can achieve the effect of splicing bones. The ball head 4 can be rotated and adjusted at a certain angle on the double rod fixator 2, which can achieve the effect of multi-directional adjustment and multi-angle fixation of bones. This solves the problem that existing reduction devices cannot pull in multiple directions at the same time. Generally, multiple reduction devices are needed to achieve the effect of pulling and reducing bones, which is inconvenient.

[0023] The second bone nails 12 on the sliders 10 on both sides and the hook block 13 can achieve the effect of assisting in fixing the bones. They can pull the bones away from the fracture point to achieve the effect of clamping and fixing the bones. The handle 9 can be removed to reduce the size of the device.

[0024] In the embodiment: the outer wall of the third bolt 11 is threadedly connected to the inner thread of the hook block 13, and the outer wall of the locking block 14 is slidably connected to the outer wall of the fixing rod 1.

[0025] Specifically, the third bolt 11 is threadedly connected to the hook block 13, which can restrict the movement of the hook block 13. When used in conjunction with the fixing rod 1, the hook block 13 can be restricted to the outside of the fixing rod 1, thus achieving the effect of fixing the hook block 13.

[0026] In the embodiment: both connectors 6 have threaded rods inside, and the outer walls of the threaded rods are respectively connected to the internal threads of the two ball heads 4;

[0027] Specifically, the connector 6 has a threaded rod inside, which is used to connect the ball head 4 and the connector 6, thus achieving a fixed connection between the ball head 4 and the connector 6.

[0028] In the embodiment: both connectors 6 have multiple threaded holes inside, and the spacing between the multiple threaded holes is equal;

[0029] Specifically, the connector 6 has multiple threaded holes, which can be used with the first bone nail 7 and adjusted according to the patient's bone position to achieve the effect of convenient adjustment and use;

[0030] In the embodiment: both connectors 6 are provided with anti-slip grooves on the side near the double rod retainer 2, and both ball heads 4 are provided with limit grooves at their bottom ends, and the limit grooves and anti-slip grooves are provided in a corresponding manner.

[0031] Specifically, an anti-slip groove is provided on the top of the connector 6, which cooperates with the limiting groove below the ball head 4 to achieve an anti-slip effect, prevent the connector 6 from rotating at the connection point with the ball head 4, and prevent the connector 6 from rotating during use;

[0032] Working principle: The first bone nail 7 is driven into both sides of the fractured bone. The handle 9 is moved to move the double-rod fixator 2, causing the connector 6 and the second bone nail 12 to move, splicing the bones together. After splicing, the first bolt 3 and the second bolt 5 are twisted. The first bolt 3 works with the double-rod fixator 2 to fix the double-rod fixator 2 to the outside of the fixation rod 1. After the second bolt 5 is tightened, the ball head 4 is clamped, restricting the ball head 4 and preventing it from moving easily. This achieves the effect of splicing the bones. The ball head 4 can be rotated and adjusted at a certain angle in the double-rod fixator 2. Compared with related technologies, the simple orthopedic reduction device provided by this utility model has the following beneficial effects: it can achieve multi-directional adjustment and multi-angle fixation of bones, solving the problem that existing reduction devices cannot simultaneously traction in multiple directions, which is inconvenient.
