Instant compression hip screw plate and instant compression hip screw system

2015 
The invention relates to the technical field of medical instruments, in particular to an instant compression hip screw plate and an instant compression hip screw system. The instant compression hip screw plate comprises a locking compression steel plate, a steel plate sleeve, a tension screw and a compression screw; the steel plate sleeve comprises an upper through hole and a lower through hole; a main part of the tension screw is provided with teeth; the compression steel plate is fixedly connected with the steel plate sleeve; the tension screw penetrates the upper through hole; the compression screw penetrates the lower through hole; a thread part of the compression screw meshes with the teeth of the main part of the tension screw; a connection of the compression steel plate and the steel plate sleeve is provided with a fixing device used for fixing the compression screw. The instant compression hip screw plate and the instant compression hip screw system have the advantages that the Z effect of a common double-screw system is avoided, poor anti-rotation capacity caused by insufficiency of anchoring force of the single screw is avoided, evident linear compression occurs to a fracture when the compression screw is driven in, such compression is direct, continuous, effective and controllable, and internal fixation failure of a DHS (dynamic hip screw) caused by excess sliding is basically avoided.
