Abstract
The invention discloses a locked-dynamic dual intensity hip screw, which is characterized by the following: opening near-end temporary fastening hole, assistance nail hole, main nail hole with bone plate as included angle, screw hole and far-end temporary fastening tank for fairshaped sharp-edged bone plate from near end to far end; fixing active sleeve barrel on the bone plate through screw thread or other connecting structure; placing the mail nail with inner hole in the sleeve barrel; arranging the inner screw thread at the lower end of the main nail hole; matching with locked rear nail; connecting the locked rear nail and the main nail; arranging sleeve barrel inner screw thread at the inner side of the sleeve barrel lower; matching with out screw thread on the nail hat of the locked rear nail; matching the nail hat screw thread of locked rear nail with the inner screw thread in the sleeve barrel; connecting the locked rear nail and the sleeve barrel. This invention possesses strong anti-rotate property and low inner fixed efficiency.
Description
1, technical field
The present invention relates to a kind of medical Orthopeadic Surgery near end of thighbone dissection bone plate, especially a kind of hip screw having two functions of locking and driving that is used for the fractured near end of thighbone internal fixation.
2, background technology
At present, using in the society and make in the outer inner fixing device of medical intertrochanteric fracture of the femur marrow many kinds are arranged, wherein comparatively advanced and representational is the dynamic hip screw system.When this system is used for the intertrochanteric fracture patient of instability mode and concurrent serious osteoporosis, have following open defect: the one, because it is that single nail is fixing, so its anti-verticity is poor; The 2nd, after inside-fixture is implanted, add and press-fit under the attitude because of be in power always, easily make the neck of femur cripetura, this phenomenon serves as obvious with intertrochanteric comminuted fracture especially; The 3rd, because the main nail of this system is too thick, cause the osteoclasia amount big, make increasing of complication such as malunion of fracture or healing difficulty; The 4th, in operative process since this system use be fixed muffle, easily make in Wicresoft's operating process nail-plate in conjunction with difficulty.
3, summary of the invention
Task of the present invention provides a kind of novel locking-power dual intensity hip screw that is enough to overcome above-mentioned defective, during this system applies locking tail nail, have fixation, anti-verticity is strong, the internal fixation crash rate is low, fracture end does not shorten, be suitable for healing, Wicresoft's convenience operation.When unloading locking tail nail, have the characteristics of common dynamic hip screw system dynamic pressurization, promotion union of fracture.Thereby founded the early stage static(al) locking of intertrochanteric fracture of the femur and had the strongest fixed effect, later stage (8～12 weeks, primary callus form back) power adds press fit and further promotes the new method of union of fracture, this intertrochanteric fracture of the femur operative treatment of callus plasticity.
For realizing above-mentioned task, the technical scheme that the present invention takes is to have the temporary fixed hole of near-end successively from near-end to far-end on its far-end is the blade plate of streamlined sharp-edged, auxilliary nail hole, become the main nail hole of angle with blade plate, screw hole, the temporary fixed groove of far-end, by screw thread or other syndeton quill is fixed on the blade plate, upper end at main nail is provided with external screw thread, the main nail that is provided with endoporus places in the sleeve, cooperate will lead to follow closely with locking tail nail by the female thread that is arranged on lower end in the main nail hole to be positioned in the sleeve, the inboard of sleeve lower end be provided with lock tail ailing medicated cap on the internal thread of sleeve that matches of external screw thread.Cooperates with internal thread of sleeve on being arranged on sleeve by the locking tail ailing cap thread that is arranged on the locking tail ailing medicated cap, the locking tail is followed closely and sleeve links together.Main nail hole on the described blade plate and the angle between the blade plate are between 110 °-160 °.
Owing to taked technique scheme, the present invention has following beneficial effect: the one, and the present invention is on the basis of continuity quill dynamic hip screw technical scheme, change common tail nail into locking tail nail, when unstable fracture and serious osteoporotic fracture, can use locking tail nail earlier, match with the female thread of main nail by locking tail oncomelania stricture of vagina, locking tail ailing cap thread matches with the female thread of quill, quill is fixed on the blade plate by external screw thread, realized making fracture end by locking tail nail, main nail, blade plate is locked as the task of one, thereby solved when unstable fracture, main nail cuts out, the defective that neck of femur shortens, reduce the inefficacy of internal fixation to greatest extent, guaranteed the functional training that do not bear a heavy burden that postoperative is early stage, after raw bone forms, take out locking tail nail, package unit becomes the dynamic hip screw system again, thereby power pressurization when realize bearing a heavy burden promotes the task of union of fracture.Can effectively realize task of the present invention in sum.
