技术领域technical field
本实用新型涉及骨科手术器械的技术领域，具体说是一种适用于亚洲人群胫骨远端部位外侧的复杂型骨折的应力消散型锁定加压接骨板。The utility model relates to the technical field of orthopedic surgical instruments, in particular to a stress-dissipating locking and pressurized bone plate suitable for complex fractures on the outside of the distal tibia of the Asian population.
背景技术Background technique
在患者的胫骨远端和胫骨干部发生复杂型骨折时通常使用安装接骨板的方法进行医治。但在接骨板的钢板安装时，都无法避免在接骨板和骨骼之间产生应力过于集中的现象，这样在康复训练后期的负重训练中，容易导致在应力集中的部位出现钢板折断的情况。传统的有限接触钢板因其下表面特有的有限接触方式结构，在钢板安装到骨骼表面以后，会形成桥梁一样点接触的“桥式定位结构”在力学分析中，“桥式定位”的优势在于：骨板和骨骼表面接触面面积小，形成三点定位，可以有效定位钢板一侧的两段断骨。但是在康复运动时“桥式定位”的接骨板与骨骼之间的扭转力完全施加给了“桥洞”上面的“桥身横梁“也就是担负着拉伸力、扭转力和折弯力在钢板表面（钢板运动折弯点位于接骨板上表面附近，一旦钢板和螺钉产生松动就会诱导接骨板的断裂。Patients with complex fractures of the distal tibia and tibial diaphysis are usually treated with plate placement. However, when the steel plate of the bone plate is installed, it is impossible to avoid the phenomenon of excessive stress concentration between the bone plate and the bone. In this way, during the weight-bearing training in the later stage of rehabilitation training, it is easy to cause the steel plate to break at the stress-concentrated part. Due to the unique limited contact structure of the lower surface of the traditional limited contact steel plate, after the steel plate is installed on the surface of the bone, it will form a "bridge positioning structure" with point contact like a bridge. In mechanical analysis, the advantage of "bridge positioning" is that : The contact area between the bone plate and the bone surface is small, forming three-point positioning, which can effectively locate two broken bones on one side of the plate. However, during the rehabilitation exercise, the torsional force between the bone plate and the bone in the "bridge positioning" is completely applied to the "bridge beam" above the "bridge hole", which is to bear the tensile force, torsion force and bending force on the steel plate. Surface (the bending point of the plate movement is located near the surface of the bone plate, once the plate and screws become loose, it will induce the fracture of the bone plate.
