Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
As shown in Figure 1, Figure 2 and Figure 3, provided respectively front view, the top and bottom perspective views of the first blade plate in the present invention, Fig. 4 has provided the cutaway view in A-A cross section in Fig. 2, and the first shown blade plate 1 is rectangle, its right-hand member is provided with 3 fixing holes, and left end is provided with boss 4.The thickness that boss 4 positions are set is greater than other positions, to increase the intensity at boss 4 positions; On shown boss 4, offer sliding tray 5 along the length direction of the first blade plate 1, offer pressurization screw 6 in boss 4 left end side, pressurization screw 6 communicates with sliding tray 5.
As shown in Fig. 5, Fig. 6 and Fig. 7, provide respectively front view, the top and bottom perspective views of the second blade plate in the present invention, Fig. 8 has provided the cutaway view in B-B cross section in Fig. 6, Fig. 9 has provided the cutaway view in C-C cross section in Fig. 6, the second shown blade plate 2 is also rectangle, the left end of the second shown blade plate 2 is fixed with U-shaped plate 7, and the opening of U-shaped plate 7, towards a left side, has formed gathering sill 8 between U-shaped plate 7; In its right end face of U-shaped plate 7, offer through hole 9, through hole 9 communicates with gathering sill 8.Gathering sill 8 matches with boss 4, and after boss 4 is placed in gathering sill 8, gathering sill 8 is realized guiding and the position-limiting action to the first blade plate 1, to ensure that the first blade plate 1 moves towards fixed-direction all the time, has avoided fracture site displacement.
As shown in Figure 10 and Figure 11, provided respectively the structural representation after the first blade plate 1 and the second blade plate 2 are combined, Figure 12 has provided the cutaway view in D-D cross section in Figure 10; The first blade plate 1 and the second blade plate 2 are individually fixed in the both sides of fracture by the fixing hole 3 on it, shown connecting bolt 11 is connected by screw thread with connecting screw hole 10 through sliding tray 5 is rear, between connecting bolt 11 and sliding tray 5, it is pad 12, because connecting bolt 11 is pressed on the upper surface of boss 4 tightly, connecting bolt 11 can not be moved in sliding tray 5, can there is not relative sliding in the first blade plate 1 and the second blade plate 2 yet, realize fixing to patient's fracture, be conducive to the healing of fracture site.Connecting bolt 13 should spill the length of the second blade plate 2 about lower surface 2mm, deviates from when avoiding connecting bolt 13 loosening.Shown in the both sides on U-shaped plate 7 tops be provided with spacing outstandingly 15, after the boss 4 of the first blade plate 1 extend in gathering sill 8, by the position-limiting action of spacing outstanding 15 pairs of boss 4, can effectively avoid the first blade plate 1 to misplace with respect to the second blade plate 2.
After the through hole 9 that shown pressurization bolt 13 is passed on the second blade plate 2, be connected by screw thread with the pressurization screw 6 on the first blade plate 1, not only strengthen between the first blade plate 1 and the second blade plate 2 and be connected, and by turning pressurization bolt 13, can make the first blade plate 1 in the interior movement of gathering sill 8, patient's fracture is exerted pressure.In the time that needs are exerted pressure to fracture, first loosening connecting bolt 11, then can order about the first blade plate 1 towards the inner movement of gathering sill 8 by turning pressurization bolt 13, realizes the pressurization to fracture; When pressurization, connecting bolt 13 can become flexible but can not unclamp, to remain the fixation to fracture site; After pressurization, then tighten connecting bolt 11.
In order to ensure the guide effect of gathering sill 8 to the first blade plate 1, the width of gathering sill 8 equates with the width of boss 4, can realize guide effect, but also can avoid fracture site to misplace.In the process of fracture site healing, can constantly exert pressure to the broken ends of fractured bone according to treatment situation, be suitable for exerting pressure and treating the occasion of fracture at needs.The shape of the first blade plate 1 and the second blade plate 2, should be consistent with the shape of placing steel plate place skeleton, to ensure the first blade plate 1 and the second blade plate 2 fixedly securing at people's external surface.
For the fastness that ensures that the first blade plate 1 is connected with the second blade plate 2, the upper and lower surface of shown boss 4 is frosting, and on the second blade plate 2, the bottom of gathering sill 8 is also frosting.Like this, after the first blade plate 1 is connected by connecting bolt 11 with the second blade plate 2, ensure to there is enough large frictional force on the first blade plate 1 and the second blade plate 2 contact surfaces, on the rubbing surface between pad 12 and the first blade plate 1, also there is enough large frictional force.
Persistent pressure formula external locking bone fracture plate of the present invention, by coordinating of gathering sill and boss, in the process of pressurization, pressure direction is all the time along fracture site longitudinal pressing, do not change other directions of steel plate, avoided fracture site displacement, can effectively solve locking bone fracture plate percutaneous is fixedly the shortcoming of cannot pressurizeing outward.
