[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] Reference Figure 1 As shown, this is an embodiment of the X-ray fluoroscopy positioning plate 1000. The X-ray fluoroscopy positioning plate 1000 includes a square frame 100 and a wire mesh 200. The square frame 100 is provided with a first scale bar 110 and a second scale bar 120 that are perpendicular to each other. The wire mesh 200 is disposed inside the square frame 100 and has a plurality of circular holes 210 that are crisscrossed along a first direction and a second direction. Both the first scale bar 110 and the second scale bar 120 are marked with numbers. The first scale bar 110 is used to indicate the number of rows of the circular holes 210 along the first direction, and the second scale bar 120 is used to indicate the number of columns of the circular holes 210 along the second direction. The first direction and the second direction are perpendicular. (See reference...) Figure 2 As shown, the X-ray fluoroscopy positioning plate 1000 can deform and bend into an arc shape.

[0026] In use, the X-ray fluoroscopic positioning plate 1000 can be bent and applied to the skin surface of the patient's limbs. Since the wire mesh 200 is a imaging element, the round holes 210 of the wire mesh 200 can be seen in the X-ray imaging. By reading the first scale bar 110 and the second scale bar 120 on the surface of the square frame 100, the position of the round hole 210 can be accurately located. The required position and direction of the nail hole inside the bone can be accurately located. When driving the locking screw, the locking screw can be driven into the position of the round hole 210, which facilitates the closure and insertion of the internal fixation screw and avoids blind driving and repeated positioning operations. This positioning plate can also locate foreign bodies that can be visualized on X-ray of the limbs. By marking the position of the round hole 210, the specific location of the foreign body can be known, which facilitates the removal of the foreign body during surgery.
