New description: [New technical field] This case relates to a fracture fixation device, especially a fracture fixation device that has a compression function and does not cause the bone screw to escape from the bone plate. [Prior Art] According to the 'every day, there are unexpected events, people have a good time, when we accidentally fall, crashed, 'the body is directly exposed to the track, if the situation is slight, only the bitterness of the flesh, when the navigation is serious The silk is caused by the "fracture" that the foot knows.

If one of them - broken bone has bone deficiency or osteoporosis, it often causes the bone to snail out. In addition to losing the effect of the mixture, the money is even used to remove the bone screw and re-solidify it. Words. . The hand I bone is screwed to the thread, which can avoid the connection between the bone screw and the bone plate of the bone plate. The wire: the plate is so that two round holes, (4) acts 'again' because of the plate hole of the bone plate The system is = the above-mentioned missing, the phase _ then the hole in the plate of the bone plate _ threaded, 3 M363896 have entered the 'such bone screw implanted, need to confirm the thread direction of the screw and the thread on the bone plate Directions. ', therefore, 'how to provide a compression effect on the two broken bones, the fracture fixation device' is a difficult problem to overcome in the relevant industry records: The main purpose of this case is to provide a kind of fracture fixation, the technical means adopted in this case is provided - The fracture plate hole is a circular and class-like plate hole, and the appropriate position of the two opposite narrow sides of the position portion is more than the portion of the position where the head is fixed: the head = ^ _ _ _ _ _ _ _ ^^ : Positioning thread, the top surface of the locking screw &========================================================================================= The utility model provides a fracture fixing device, wherein the inner wall of the plate portion is provided with a positioning thread by a - convex ring in the hole; the lower crossing portion is in the position: 4 less edge; Π: head:: head „open At least - locking, its circumference:: has a convex locking edge 4 M363896: the top surface of the locking screw has a groove 'bottom and has a pressing surface, which can press the bearing surface of the adjacent bone screw below /, 掣图 The age of the case (10), the first scale ginseng _ type, wherein, Figure 1 is the fracture fixation device of this case The top view of the first embodiment after the combination of the fracture fixation device shown in Fig. 3 is a cross-sectional view taken from Fig. 2, and Fig. 4 is a cross section taken along line Β = line Α-Α. Show 胥軿 in — Zhuang class, the profile of the person from the bully, Figure 5 is the figure fixed. Figure 6 is a cross-sectional view of the bone device after the combination. 胄7 is the fixed fracture of Figure 6 [embodiment] Ί The upper bone bending device is composed of a bone screw 2 and at least a locking screw 3. The middle plate 1 is a plate body, and the scale is, for example, as shown in Fig. 1, the bottom surface of the bone plate has It is limited to the surface of the two broken bones of the metal plate. The bone plate is _ 2 concave, and the surface 11 ' is attached to the plate hole 12 to form an oblong shape ^ as shown in FIG. 1 , and the convex ring 121 is divided into The upper part of the plate hole I2 is positioned by the bottom of the inner portion 与22 and the rim of the convex ring 121=122 and the traversing portion 123 below, and the two opposite sides of the positioning are appropriately inclined, and the positioning portion 122 is provided for the rear. The locking screw 3 has a pair of positioning threads 122b, such as a mid-long recess, so that the 21-to-concave bearing surface 212 and the "=" are characterized by a top surface shape of For the customary-shaped groove, the cross-shaped groove, the outer screw 22 outer /- I is integrally connected with a threaded rod 22 below the head 21, and the outer thread 22 is rotated from the smaller than the convex ring groove 213, The inner diameter of the thread H is made, so that the cross section of the two broken bones directly locked by the tool is passed through the crossing portion 123' below the plate hole 12, and the flange 211 is pressed against the convex ring 121, From M363896, the expected compression of the two broken bones was achieved. The locking screw 3 is a cylinder with a locking thread on its circumference, and the top surface isrt32, the side tool is inserted into the (10) 32 and rotated to lock The thread finds the positioning thread 彳 22b preset by the clamping portion 22 so that the bottom of the locking screw 3 can abut against the top of the bone screw 2, thereby preventing the bone screw 2 from coming out. When the locking screw 3 having an arcuate projection on the bottom of the locking screw 3 is locked to the positioning portion 122, the pressing surface 33 is 212' to achieve an optimum clamping effect. This turn--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- The second embodiment can still maintain the __ system, but the vertical diagram is as shown in FIG. 7 , which is the second embodiment of the present invention. The difference between the foregoing embodiments is that the plate hole 彳 2 is a circle. The hole is shaped like a grade, and the inner wall of the upper positioning portion 122 is straight: 122b, 'for the purpose of locking the screw of the lion 3. .累 累 M ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ The same close connection effect can also be obtained. The facing surface 33 is a curved concave surface 'not straight: the following::: The effect is that the _ wire is used together. In addition, the sputum will not be detached from the bone plate. In particular, even if the two screws are pressed, so that the long hole provided by the embodiment is selected and there is a bone defect, the first joint of the case is to avoid the bone = 1 = at an oblique angle The two broken bones are restricted by the thread direction of the plate hole m5 of the bone plate, and the bone screw of the case is locked to the bone plate because it does not need 6 M363896. Therefore, the bone screw is locked. It is not restricted, and it is a great structure that has never been seen before. The disclosure of the present invention is a preferred embodiment of the present invention, and the person who is familiar with the technical idea of the case and who is familiar with the skill of the case is not in the scope of the patent right of the case. , inferred, [schematic description of the drawings] Figure 1 is a perspective exploded view of the first embodiment of the fracture fixation device of the present invention.
