Embodiment Construction
[0024] The following combination Figure 1~8 , the content of the present invention will be described in detail through specific embodiments. The bone plate system includes a plate body 1 with several screw holes and a screw 2 passing through the screw holes for fixing the plate body 1. The plate body is composed of a backbone fixing part 102 and a bone end fixing part 101. Inside the screw holes are Arc structure, the screw arc structure 25 matched with the screw hole arc structure 31 is arranged on the lower surface of the end of the screw 2 .
[0025] The left and right sides of the backbone fixing part 102 are provided with a number of steel plate gaps 30 at equal intervals, and two or four or six screw holes are sequentially arranged along the length direction of the backbone fixing part 102, and a tooth profile is provided between the two screw holes in the middle. Slot 32. The toothed groove 32 is limited by a toothed screw assembly, which is composed of a screw assem...

The invention discloses a bone joining steel plate system which comprises a steel plate main body with a plurality of screw holes and screws which are used for fixing the steel plate main body and penetrating through the screw holes, wherein the main body consists of a bone rod fixing part and a bone end fixing part; the bone joining steel plate system is technically characterized in that arc-shaped structures are arranged in the screw holes; the lower surfaces of the end parts of the screws are matched with the arc-shaped structures in the screw holes; two buckling plate slots with symmetric structures are formed in the bone end fixing part along the length direction; buckling plate screw holes are formed in the centers of the buckling plate slots; screw holes are symmetrically formed in the two ends of each buckling plate slot; screw holes are formed along the connecting direction of the circle centers of the two buckling plate screw holes; buckling plates matched with the shapes of the buckling plate slots are fixed in the buckling plate slots; spherical bulges are respectively arranged at the bottoms of the two ends of the buckling plates; buckling plate mounting holes concentric with the buckling plate screw holes are formed in the middle parts of the buckling plates; the buckling plates are fixed in the buckling plate slots through the buckling plate screws penetrating through the buckling plate mounting holes. According to the bone joining steel plate system, the problems that an existing bone joining steel plate is inconvenient to use, single in function, low in intensity and low in fixing stability, cannot realize fine adjustment and the like are solved fundamentally.
Description
technical field [0001] The invention relates to the field of medical devices, in particular to a special device for bone setting, specifically a bone setting plate system, which is mainly suitable for the joint and fixation of tibial fractures. Background technique [0002] Surgeons use a variety of equipment and techniques to treat patients. In some procedures, medical devices are used to join, stabilize and / or fix one or more bones, bone fragments or tissue pieces. Similar techniques and equipment can be used in spinal surgery, especially spinal fusion surgery. In some of these procedures, the plate may be fixed to one or several vertebrae. These plates are usually symmetrical and are usually fixed centrally on the spine. [0003] For example, the invention patent application with the application publication number CN103826559A discloses "a spinal board for installation on one or more vertebrae". The spinal plate may be an asymmetrical cervical plate. The cervical pla...
