[0001] The utility model relates to the technical field of fixing devices, in particular to a minimally invasive fixing device for orthopedic surgery. Background Art

[0002] Orthopedic minimally invasive surgery is a surgical method that performs surgical operations through small incisions or natural body cavities to achieve the purpose of treating orthopedic related diseases. With the rapid development of medical technology, orthopedic minimally invasive surgery has gradually become the mainstream of orthopedic surgery due to its advantages of small trauma, fast recovery, and few complications.

[0003] Most of the existing orthopedic minimally invasive surgeries use fixing brackets for fixation after the operation. However, due to structural problems during use, the current fixing brackets are prone to insufficient fixing effect, and the fixing screws will continuously compress the skin, which will affect the skin condition over a long time. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems that when the above-mentioned equipment is used, due to the insufficient stability of the existing fixing brackets, it affects the recovery of bones, and the long-term compression of the skin by the fixing screws affects the skin condition, and a minimally invasive fixing device for orthopedic surgery is proposed.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A minimally invasive fixing device for orthopedic surgery, including four support plates. A set of holes one are opened on the outer surface walls of the four support plates. Fixing screws are movably inserted into the inner surface walls of the four sets of holes one. The outer surface walls of the four groups of fixing screws are provided with an injured body. Two wrapping cloths are arranged on the outer surface wall of the injured body. Two sets of holes two are opened on the outer surface walls of the two wrapping cloths. Two connecting plates one are fixedly installed on the outer surface walls of the four support plates.

[0006] Preferably, a set of threaded holes one are opened on the tops of the eight connecting plates one. Screws one are threadedly connected between the inner surface walls of every two of the eight sets of threaded holes one. Pressure sensors are fixedly installed on the tops of the four support plates.

[0007] Preferably, connecting frames are fixedly installed on the opposite sides of the four support plates. Holes three are opened on the outer surface walls of the four connecting frames.

[0008] Preferably, movable rods one are movably inserted into the inner surface walls of the four holes three. Movable plates are fixedly sleeved on the outer surface walls of the four movable rods one.

[0010] Preferably, connecting plates II are fixedly installed on the outer surfaces of the four connecting frames, and threaded holes II are formed in the outer surfaces of the four connecting plates II.

[0011] Preferably, screws II are threadedly connected to the inner surfaces of the four threaded holes II.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0013] 1. In the present utility model, first, by adjusting the alignment positions of the threaded holes at the tops of each connecting plate I and fixing them with screws I, every two support plates are connected. The support plates directly act on both sides of the fracture site, and the fracture ends are tightly fixed together through the clamping action, effectively preventing the displacement and misalignment of the fracture site, ensuring that the fracture ends heal at the correct positions. Secondly, fixing screws are used to connect and fix the device to the patient. The fixing screws are tightly combined with the bone through threads, capable of providing strong fixing force, ensuring that the fracture site heals stably at the correct position.

[0021] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the limitations of the specific embodiments disclosed in the following specification.

[0023] Embodiment 1, as Figure 1 、 Figure 2 shown, the present invention provides a minimally invasive fixation device for orthopedic surgery, including four support plates 1. A set of first holes 2 are opened on the outer surface walls of the four support plates 1. Fixing screws 3 are movably inserted into the inner surface walls of the four sets of first holes 2. An injured body main body 4 is arranged on the outer surface walls of the four sets of fixing screws 3. Two wrapping cloths 5 are arranged on the outer surface wall of the injured body main body 4. Two sets of second holes 6 are opened on the outer surface walls of the two wrapping cloths 5. Two first connecting plates 7 are fixedly installed on the outer surface walls of the four support plates 1. A set of first threaded holes 8 are opened on the tops of the eight first connecting plates 7. First screws 9 are threadedly connected between the inner surface walls of every two sets of the eight sets of first threaded holes 8. Pressure sensors 10 are fixedly installed on the tops of the four support plates 1.

[0024] The effect achieved by the entire Embodiment 1 is as follows. First, adjust the distance between every two support plates 1 according to the size of the injured body main body 4. Then, align the first threaded holes 8 at the tops of every two first connecting plates 7. Next, pass the first screw 9 through the first threaded holes 8 to fixedly connect every two support plates 1. Secondly, pass the fixing screws 3 through the first holes and into the interior of the injured body main body 4 to connect the device to the patient. The implantation of the fixing screws 3 can be carried out through precise guidance and positioning during the operation to ensure that the fixing screws 3 can be accurately implanted into the predetermined positions. This precision helps to improve the accuracy of the operation and reduce the surgical risks. Cooperating with the four support plates 1 makes the fixation more comprehensive. At the same time, a pressure sensor 10 is provided near each fixing screw 3. When abnormal changes occur in the pressure at the fixing screw 3, the pressure sensor 10 can timely send a warning signal to the doctor, which helps the doctor to timely discover and handle potential problems, such as loosening, fracture of the fixing screw 3 or compression of the surrounding tissues, thereby improving the safety of the operation.

[0025] Embodiment 2 is as Figures 1-4 shown. Connecting frames 11 are fixedly installed on the opposite sides of the four support plates 1. Through holes three 12 are formed in the outer surfaces of the four connecting frames 11. First movable rods 13 are movably inserted into the inner surfaces of the four through holes three 12. Movable plates 14 are fixedly sleeved on the outer surfaces of the four first movable rods 13. Through holes four 15 are formed in the outer surfaces of the four movable plates 14. Second movable rods 16 are movably inserted between the inner surfaces of every two of the four through holes four 15. Connecting plates two 17 are fixedly installed on the outer surfaces of the four connecting frames 11. Second threaded holes 18 are formed in the outer surfaces of the four connecting plates two 17. Second screws 19 are threadedly connected to the inner surfaces of the four second threaded holes 18.

[0026] The effect achieved by the entire Embodiment 2 is as follows. When the device is in normal use, every two of the four movable plates 14 are connected by the second movable rods 16, and the second movable rods 16 can be adjusted according to the size of the injury site. Secondly, after the adjustment is completed, since the connecting frames 11 are fixedly connected to the connecting plates two 17 and the second threaded holes 18 are formed in the outer surfaces of the connecting plates two 17, rotate the second screws 19 into the second threaded holes 18 to apply pressure to the first movable rods 13 to fix the first movable rods 13. By precisely adjusting the angle of the bracket, the doctor can ensure that the fracture site is stably fixed, reducing the risk of complications caused by unstable fixation.

[0027] Among them, the pressure sensor 10 is a prior art, and its components and working principles are all publicly known technologies, so no more explanations will be given here.

[0028] Working principle: Firstly, when fixing the injured part of the patient, two wrapping cloths 5 are respectively bandaged above and below the injured part. The wrapping cloth 5 has the characteristic of good air permeability, which helps to keep the environment around the wound dry, reduce the accumulation of exudate, and create favorable conditions for wound healing. Secondly, two connecting plates one 7 are fixedly installed on the outer surface walls of the four support plates 1. A set of threaded holes one 8 are opened at the tops of the eight connecting plates one 7. According to the size of the injured body 4, the alignment positions of the threaded holes one 8 at the tops of the connecting plates one 7 are adjusted. Secondly, a screw one 9 is used to pass through the inner surface walls of every two threaded holes one 8 for fixation. Secondly, a set of holes one 2 are opened on the outer surface walls of the four support plates 1. Fixed screws 3 are movably inserted into the inner surface walls of the four sets of holes one 2. By passing the fixed screws 3 through the holes one 2 and inserting them into the injured body 4, the fixed screws 3 cooperate with the four support plates 1 to fix the fracture site in multiple directions, ensuring that the fracture ends are comprehensively stabilized in three-dimensional space. This multi-directional fixation method helps to promote the healing of fractures and reduce complications caused by unstable fixation. At the same time, pressure sensors 10 are fixedly installed at the tops of the four support plates 1. By setting pressure sensors 10 at each fixed screw 3, doctors can ensure the best fixation effect for the fracture site, which helps to promote the healing and recovery of fractures and shorten the rehabilitation time of patients. Secondly, movable rods one 13 are movably inserted into the inner surface walls of the four holes three 12. Movable plates 14 are fixedly sleeved on the outer surface walls of the four movable rods one 13. Every two movable plates 14 are connected by a movable rod two 16. The angle of the movable plates 14 can be adjusted to make the bracket adapt to the injured parts of different lengths. Secondly, connecting plates two 17 are fixedly installed on the outer surface walls of the four connecting frames 11. Threaded holes two 18 are opened on the outer surface walls of the four connecting plates two 17. By rotating the screw two 19 into the threaded hole two 18, the screw two 19 presses the movable rod one 13 to fix the movable rod one 13 and prevent the bracket from moving, resulting in unstable fixation. The stable fixation effect helps to relieve the pain and discomfort of the patient and improve the quality of life of the patient.

[0029] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
