There are 29 skull bones, 51 trunk bones, and 126 limb bones. Skeletalization is the basis for the complexity of biological structures, and the skeletal system is also a limiting factor in the evolution of biological morphology. The skeleton is a hard organ that makes up the endoskeleton of vertebrates. Its functions are to move, support and protect the body, produce red blood cells and white blood cells, and store minerals.

[0022] 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.

[0023] Please see Figures 1-5 This novel combined external fixation skeletal orthopedic framework offers two technical solutions:

[0024] The first embodiment includes a base 1, a rotating seat 2 connected to the base 1 with damping, a slide rail 3 fixedly connected inside the base 1, and a slide rail 3 fixedly connected to the top of the rotating seat 2. Both slide rails 3 are provided with at least two adjustment components 4, and the adjustment components 4 are provided with an insertion component 5 with fine adjustment function.

[0025] The insertion assembly 5 includes a first lead screw 51, which is threadedly connected to the adjustment assembly 4. Two sliding rods 52 are slidably connected to one end of the first lead screw 51, and Kirschner wires 53 are fixedly connected to one end of each sliding rod 52. An annular groove 54 is formed on the inner surface of the first lead screw 51, and a limiting ring 55 is rotatably connected to the annular groove 54. A second lead screw 56 is fixedly connected to the inner surface of the limiting ring 55, extending to the outside of the first lead screw 51. The Kirschner wires 53 and the second lead screw 56 are located outside the first lead screw 51. The surface is threaded. The second lead screw 56 is fitted with a rotating handle 57, which can be switched to rotate the first lead screw 51 and the second lead screw 56 respectively. Two limiting rods 58 are fixedly connected to one side of the rotating handle 57. One end of the first lead screw 51 is provided with two first limiting grooves 59 that cooperate with the limiting rods 58. Two second limiting grooves 511 are opened on one side of the rotating handle 57. One end of the second lead screw 56 is fixedly connected with two limiting blocks 510 that cooperate with the second limiting grooves 511.

[0026] The adjustment assembly 4 includes a support base 41. The front of the support base 41 has two upper and lower sliding grooves 42. The inner surfaces of the two sliding grooves 42 are slidably connected to pressure plates 43. The structure formed by the support base 41 and the pressure plates 43 is sleeved on the outside of the slide rail 3. A fixing bolt 44 is fixedly connected to the right side of the support base 41. The fixing bolt 44 passes through the inside of the slide rail 3 and the pressure plates 43. A locking sleeve 45 is threadedly connected to the surface of the fixing bolt 44 on the right side of the pressure plates 43. Loosening the locking sleeve 45 allows the height and left and right position of the Kirschner wire 53 to be adjusted. After adjustment, tightening the locking sleeve 45 is sufficient.

[0027] After the Kirschner wire 53 is positioned and inserted into the human body by adjusting the position of the first lead screw 51, if the position is not accurate, the position of the Kirschner wire 53 can be finely adjusted by rotating the second lead screw 56, thereby ensuring the accuracy of the insertion and improving the practicality of the device.

[0028] The second embodiment differs from the first embodiment in that a protective component 6 is provided on the Kirschner wire 53. The protective component 6 includes a silicone sleeve 61 and an antibacterial membrane 63. Both the silicone sleeve 61 and the antibacterial membrane 63 are fitted over the outside of the Kirschner wire 53, and the silicone sleeve 61 and the Kirschner wire 53 are press-fitted. The silicone sleeve 61 has a plurality of through holes 62 evenly opened inside. The antibacterial membrane 63 is a polytetrafluoroethylene microporous film.

[0029] A protective component is installed at the insertion site of the Kirschner wire 53. An antibacterial membrane 63 is pressed onto the insertion site by a silicone sleeve 61, which ensures air permeability while preventing external dust and bacteria from infecting the wound, thus improving the safety of the device during use.

[0030] In use, place the entire support on the torso of the body to be corrected, move the rotating handle 57, and rotate the rotating handle 57 to align the limiting rod 58 with the first limiting groove 59, so that the limiting rod 58 is inserted into the first limiting groove 59. Rotate the rotating handle 57 to rotate the first lead screw 51 and move the first lead screw 51, thereby driving the Kirschner wire 53 to move. After the Kirschner wire 53 enters the human body, move the rotating handle 57 to align the second limiting groove 511 with the limiting block 510, so that the limiting block 510 enters the second limiting groove 511. Then, rotate the second lead screw 56 by rotating the rotating handle 57. The second lead screw 56 rotates and moves the Kirschner wire 53, thereby completing the fine adjustment. In addition, push the silicone sleeve 61 to move and press it to the insertion port, so that the antibacterial film 63 is in the insertion port.
