Abstract
The invention discloses a locking metal bone fracture plate device commonly used for cortical bone and cancellous bone. The device is a fracture setting medical instrument and can be used for fixing a skeleton of different bone substances at a fracture position. The device comprises a locking metal bone fracture plate, a locking coarse-pitch thread bone screw and a locking fine-pitch thread bone screw. Same taper screw threads are arranged at the rear ends of the two locking bone screws, coarse-pitch threads and fine-pitch threads are respectively arranged on the surface of a cylinder, and the locking metal bone fracture plate is provided with more than two tapered screw thread locking holes which are matched with the taper screw threads of the locking bone screws. The coarse-pitch threads are single threads or multiple threads, the fine-pitch threads and the taper screw threads are multiple threads, and the lead of the coarse-pitch threads, the lead of the fine-pitch threads and the lead of the taper screw threads are the same. In the fracture setting process, the locking coarse-pitch thread bone screw is screwed into one tapered screw thread hole corresponding to the cancellous bone at the fracture position, the locking fine-pitch thread bone screw is screwed into one tapered screw thread hole corresponding to the cortical bone, and therefore the holding force of skeletons of different substances at the two ends of a fracture line is enhanced.

Summary of the invention
In order to address the above problem, the invention provides the general locking metal bone fracture plate device of a kind of cortical bone and spongy bone, this device can be used locking coarse-pitch thread bone screw and locking fine thread bone screw on a locking metal bone fracture plate simultaneously, it comprises locking metal bone fracture plate, locking coarse-pitch thread bone screw, locking fine thread bone screw, the quantity of locking coarse-pitch thread bone screw and locking fine thread bone screw is more than one, the rear end of described locking coarse-pitch thread bone screw and locking fine thread bone screw is provided with identical tapered tread, the rear end of locking bone screw is the large end of tapered tread, the rear end of the small end of tapered tread and locking bone screw cylindrical portion joins, the periphery of described locking coarse-pitch thread bone screw is provided with coarse-pitch thread, the periphery of described locking fine thread bone screw is provided with fine thread, the close skeleton of described locking metal bone fracture plate is simultaneously for below, being provided with and the tapered tread lock hole connecting below above of locking metal bone fracture plate, the large end of tapered tread lock hole is on locking metal bone fracture plate, small end is below locking metal bone fracture plate, the quantity of described tapered tread lock hole is more than two, and match with the tapered tread of described locking bone screw, described coarse-pitch thread is single thread or multi start thread, fine thread and tapered tread are multi start thread, and multi start thread is generally double thread or quadruple thread, it is characterized in that coarse-pitch thread, fine thread, the helical pitch of tapered tread is identical.
The material of the locking metal bone fracture plate in the general locking metal bone fracture plate device of cortical bone of the present invention and spongy bone, locking coarse-pitch thread bone screw, locking fine thread bone screw be metal or nonmetal in can be used for manufacturing the material of blade plate, bone screw.
The locking metal bone fracture plate device that cortical bone of the present invention and spongy bone are general, can be on a locking metal bone fracture plate, according to the skeleton of different sclerotin corresponding below its tapered tread lock hole, screw in corresponding locking bone screw, spongy bone screws in locking coarse-pitch thread bone screw, cortical bone screws in locking fine thread bone screw, thereby increase the hold to the different sclerotin skeletons in fracture line two ends, and then the stability of having promoted bone-setting treatment, effectively overcome the aforesaid drawbacks of existing locking metal bone fracture plate device.
Accompanying drawing explanation
Fig. 1 is the embodiment schematic diagram of the general locking metal bone fracture plate device of cortical bone of the present invention and spongy bone;
Fig. 2 is locking coarse-pitch thread bone screw schematic diagram;
