Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and in particular to an external fixation treatment device for distal radius fractures. Background Art
[0002] The human forearm consists of two bones, namely the radius and the ulna. The radius is located on the outer side of the forearm. The distal end of the radius participates in the formation of the wrist joint and plays a significant role in functions such as grasping and eating by humans. Distal radius fractures often occur in daily life. There are mainly two treatment methods for distal radius fractures. One is conservative treatment, and the other is surgical treatment. The probability of using conservative treatment methods clinically is relatively high, but not all patients or situations are suitable. When the distal radius fracture is relatively complex or severe, conservative treatment usually does not play an ideal role, and surgical treatment needs to be actively used. The commonly used method clinically is Kirschner wire fixation. However, when using Kirschner wires, usually part of them is fixed inside the body and part is exposed outside the skin. The tail exposed outside the skin is fixed through a fixing frame. Generally, the Kirschner wires need to be removed after 8 - 12 weeks. The Kirschner wires protruding outside the body are likely to catch on clothes or other things, which affects the recovery of patients. In view of the problems existing in the prior art, we provide an external fixation treatment device for distal radius fractures. Summary of the Invention
[0003] In view of the above problems in the prior art, the present invention provides an external fixation treatment device for distal radius fractures, which is achieved through the following technical solutions:
[0004] An external fixation treatment device for distal radius fractures includes a fixing frame. The fixing frame includes two fixing seats, and the two fixing seats are connected by a ball head. A connecting seat is slidably connected to the fixing seat. The connecting seat is connected to a Kirschner wire. A clamping groove is formed on the upper end surface of the fixing seat. A protective cover is clamped on the connecting seat, and the protective cover passes through the clamping groove and is clamped on the fixing seat.
[0005] The present invention is further provided as follows: The protective cover includes a clamping seat. The clamping seat is U-shaped, and the opening of the clamping seat faces downward and is clamped with the connecting seat. A support rod is connected to the center position of the upper end of the clamping seat. The upper end of the support rod is connected to a cover plate. A rectangular corrugated pipe is fixedly connected to the lower end surface of the cover plate. One end of the rectangular corrugated pipe away from the cover plate is fixedly connected to a first magnet ring. A second magnet ring is fixedly connected to the upper end surface of the clamping seat. The second magnet ring is magnetically connected to the first magnet ring. The rectangular corrugated pipe covers the outside of the Kirschner wire.
[0006] The present invention is further provided as follows: The support rod includes a rotating cylinder and a screw rod. The lower end of the rotating cylinder is rotatably connected to the clamping seat. The lower end of the screw rod is threadedly connected to the upper end of the rotating cylinder. The cover plate is fixedly connected to the upper end surface of the screw rod.
[0007] In summary, the beneficial technical effects of the present invention are as follows:
[0008] The protective cover covers the Kirschner wire protruding from the connecting seat, thereby preventing the Kirschner wire from protruding from the connecting seat and catching other things, resulting in the movement of the Kirschner wire and affecting the recovery of the patient.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0014] The present invention will be further described in detail below with reference to the accompanying drawings.
[0015] Embodiment
[0016] As Figures 1-4 shown, a distal radius fracture external fixation treatment device disclosed by the present invention includes a fixing frame 1. The fixing frame 1 includes two fixing seats 11. The two fixing seats 11 are connected by a ball head. A connecting seat 2 is slidably connected to the fixing seat 11. The connecting seat 2 is connected with a Kirschner wire 3. A clamping groove 12 is formed on the upper end surface of the fixing seat 11. A protective cover 4 is clamped on the connecting seat 2. The protective cover 4 passes through the clamping groove 12 and is clamped on the fixing seat 11. The protective cover 4 covers the Kirschner wire 3 protruding from the connecting seat 2, thereby preventing the Kirschner wire 3 from protruding from the connecting seat 2 and catching other things, resulting in the movement of the Kirschner wire 3 and affecting the recovery of the patient.
[0017] The protective cover 4 includes a clamping seat 41. The clamping seat 41 is U-shaped, with its opening facing downward and being clamped to the connecting seat 2. At the center position of the upper end of the clamping seat 41, a support rod 42 is connected. The upper end of the support rod 42 is connected to a cover plate 43. A rectangular bellows 44 is fixedly connected to the lower end surface of the cover plate 43. One end of the rectangular bellows 44 away from the cover plate 43 is fixedly connected to a first magnet ring 45. A second magnet ring 46 is fixedly connected to the upper end surface of the clamping seat 41. The second magnet ring 46 is magnetically connected to the first magnet ring 45. The rectangular bellows 44 covers the outside of the Kirschner wire 3. When covering the Kirschner wire 3, first pass the clamping seat 41 through the clamping groove 12 and clamp it on the connecting seat 2, and then attract and connect the first magnet ring 45 and the second magnet ring 46. The clamping seat 41 is made of a plastic material with a certain elasticity, and the notch of the clamping seat 41 is in interference fit with the connecting seat 2.
[0018] The support rod 42 includes a rotating cylinder 421 and a screw rod 422. The lower end of the rotating cylinder 421 is rotatably connected to the clamping seat 41, and the lower end of the screw rod 422 is threadedly connected to the upper end of the rotating cylinder 421. The cover plate 43 is fixedly connected to the upper end surface of the screw rod 422. The height of the support rod 42 can be adjusted according to the height of the Kirschner wire 3 protruding from the connecting seat 2. When adjusting the height of the support rod 42, rotate the rotating cylinder 421 to the side away from the cover plate 43.
