背景技术Background technique
在骨外科手术接骨内固定中，早期采用的是一块带有若干个通孔的钢板，将钢板放置在骨折处，用接骨螺钉穿过钢板上的通孔后与骨头相固定。随着医疗水平的不断发展，接骨板的种类不断增加，针对各个不同的部位大多都有专用的接骨板，其中环抱接骨板就属于其中一种。目前所使用的环抱接骨板通常包括一个板体，板体的两侧分别设置有对称的2至6组固定爪，板体中排列设置有若干个与接骨螺钉相配合的通孔。使用时，通过接骨螺钉穿过通孔后与骨骼相固定，并且通过固定爪与骨骼相环抱式锁定。目前所使用的环抱式接骨板的缺点是：接骨螺钉与通孔配合时难免存在一定间隙，使得该接骨板会出现松动现象。另外，由于固定爪为对称设置，在环抱骨骼时，在骨骼的纵向方向上，固定爪与骨骼的接触面积有限，从而导致环抱锁定的并不非常牢靠。In orthopedic internal fixation of bone surgery, early stage adopts a steel plate with several through holes, the steel plate is placed on the fracture, and the bone screw is fixed to the bone after passing through the through holes on the steel plate. With the continuous development of the medical level, the types of bone plates continue to increase, and most of them have special bone plates for different parts, and the encircling bone plate is one of them. The currently used embracing bone plate generally includes a plate body, two to six groups of symmetrical fixing claws are respectively arranged on both sides of the plate body, and several through holes for matching with bone screws are arranged in the plate body. When in use, the bone screw is fixed to the bone after passing through the through hole, and is locked in an embracing manner with the bone by the fixing claw. The disadvantage of the currently used embracing bone plate is that there is inevitably a certain gap when the bone screw cooperates with the through hole, so that the bone plate will loosen. In addition, since the fixing claws are arranged symmetrically, when embracing the bone, the contact area between the fixing claw and the bone is limited in the longitudinal direction of the bone, so that the embracing and locking are not very firm.
