Embodiment 1
[0027] Embodiment 1 is basically as follows:
[0028] A retractor for distal radius fractures such as figure 1 As shown, it includes a fixed plate 1, the right end of the fixed plate 1 is fixedly connected with an elbow rest 10, and the left end of the fixed plate 1 is connected with a pulling plate 2. The lower surface of the fixed plate 1 is provided with a groove 11 and is connected with the rotating assembly 3 .
[0029] Such as figure 2 As shown, the rotating assembly 3 includes a rotating rod 30, which is rotationally connected with the fixed plate 1. The rotating rod 30 includes a spline shaft 1 31, a threaded section 33 and a spline shaft 2 34, and the spline shaft 1 31 corresponds to the groove 1 11 positions are set, the spline shaft 1 31 is set with a spline sleeve 32, the threaded section 33 is located at the left end position of the groove 11, the fixed plate 1 is provided with a threaded hole 13, and the threaded section 33 can be threaded with the threaded ho...
Embodiment 2
[0037] The difference from Embodiment 1 is that, as Figure 4 As shown, a grip bar 22 is fixed on the upper surface of the pulling plate 2 . The patient can hold the grip bar 22 with his hand, and then fix his hand and the stretching plate 2 with a bandage 40 to improve the stretching stability.
Embodiment 3
[0039] The difference from implementation one is that, if Figure 5 As shown, a rotating plate 23 is detachably fixedly connected to the pulling plate 2 by bolts, and the rotating plate 23 is provided with a groove, and the palm of the patient can be put into the groove of the rotating plate 23 . During the pulling process, the doctor needs to make the palm and the arm form a certain angle according to the fracture situation. When the rotating plate 23 is installed, the rotating plate 23 can be fixedly installed at an angle with the middle line of the pulling plate 2. After the palm is put into the groove, the palm and the arm are at a certain angle.
