Embodiment 1
[0048] Example 1: Using a figure 1 The visualized distal intramedullary nail sight is shown to target the keyhole of the distal end of the intramedullary nail. Although the distal hole of the intramedullary nail is located in the medullary cavity and cannot be directly observed, under the condition of C-arm fluoroscopy, the height can be adjusted by The reference needle 10 and the translation angle are adjusted with reference to the needle 11, so that the sight installation sleeve can be adjusted synchronously, and finally the axis of the sight installation sleeve corresponds to the axis of the distal hole of the intramedullary nail. Since the height reference needle 10 and the translation angle reference needle 11 are located outside the body and can be directly seen, and can be projected on the display screen, the distance and angle measurement program can be used in the main body of the C-arm machine to display the movement of the perspective line For the distance or swing an...
Embodiment 2
[0063] Example 2: On the basis of Example 1, refer to Figure 19 , An intramedullary nail leveling mechanism including a fixed post 12, a cross brace 13, a positioning seat 14 and a lateral extension rod 15 is adopted. The cross brace 13 in the mechanism is fixed to the top of the fixed post 12, and the lateral extension The rod 15 is fixed on the side of the fixed column 12, the end of the cross brace 13 is fixed with a positioning seat 14, the positioning seat 14 contains a transverse perforation for penetrating the intramedullary nail, and the end of the lateral extension rod 15 is provided with a card slot and matched with an adjustment sleeve. Screw nut 17, a lifting screw 18 penetrates the through hole of the upper and lower walls of the slot 16 and then is threadedly connected with the adjusting screw nut 17. The upper end of the lifting screw 18 is vertically fixed with a shaft sleeve 19, the shaft sleeve 19 is covered with a rotating shaft 22, and the shaft sleeve 19 sid...
Embodiment 3
[0064] Embodiment 3: On the basis of embodiment 1, in the levelness adjusting device 5, the horizontal rotation part 504 of the upper plate 501 and the middle plate 502, and the vertical rotation part 505 of the middle plate 502 and the lower plate 503 can also be hinged. . Or install a torsion spring on the hinge of the hinge, and adjust it with the adjusting wire.
