技术领域technical field
本实用新型属于医疗器械技术领域，具体是一种股骨双侧定位钢板。The utility model belongs to the technical field of medical devices, in particular to a femoral bilateral positioning steel plate.
背景技术Background technique
在股骨骨折的医治过程中，在骨折部位施加压力有助于愈合。而目前的股骨定位钢板一般是单侧固定的，通过锁定螺钉将定位钢板固定在股骨上，钢板、骨折端均容易松动。现有的股骨钢板一般仅通过单侧钢板螺钉固定，无法为骨折端双侧处提供压力，导致骨折处愈合速度慢，甚至导致内固定物失败、骨折端不愈合。为弥补股骨骨干骨折治疗手段和手术器械的不足，急需提供治疗股骨干骨折的疗效好、愈合快的器械。During the treatment of a femoral fracture, applying pressure to the fracture site can aid in healing. The current femoral positioning plate is generally fixed unilaterally, and the positioning plate is fixed on the femur by locking screws, and the plate and the fracture end are easily loosened. Existing femoral plates are generally only fixed by unilateral plates and screws, which cannot provide pressure on both sides of the fracture end, resulting in slow fracture healing, and even failure of the internal fixator and nonunion of the fracture end. In order to make up for the lack of treatment methods and surgical instruments for femoral shaft fractures, it is urgent to provide devices with good curative effect and fast healing for femoral shaft fractures.
