Abstract
The utility model discloses an universal locking plate of thighbone near -end comprises steel sheet and supporting screw, and the steel sheet is the arc, with before the thighbone near -end, cambered surface outer, the rear side is identical to it is attached in the thighbone near -end outside to be parcel form, and the primary structure characteristic is, the front end of steel sheet be barb 1, and the steel sheet front portion does backward in proper order, and steel sheet constriction part division has two arbitrary holes 2, the steel sheet increases wide section and divide to open and to have three interim fixed orifices 3, 4 and universal dual -purpose holes of locking pulling force 5 in the three universal locking hole, the rectangular part of steel sheet rear portion constriction is opened there is the dual -purpose hole of a 6 -9 locking pressurizing, supporting screw is for hollow, is interior hexagonal type in its tail end, the outer ball -type screw thread that is. An universal locking plate of thighbone near -end board is multi -purpose, can effectually fix the multiple fracture of cracked thighbone near -end, like femoral neck fracture, intertrochanteric fracture, subtrochanteric fracture etc.
Description
Technical field
This utility model relates to a kind of orthopedic medical device, refers in particular to a kind of near end of thighbone universal lock steel plate.
Background technology
In the repair process of femur, fractured near end of thighbone, as fracture of femoral neck, intertrochanteric fracture and subtrochanteric fracture, is common major injury.Particularly due to the particularity that neck of femur is dissected, once fracture, it resets and fixes all very difficult, normal generation nonunion and ischemic necrosis of femoral head, therefore disability rate is also higher.At present for the Therapeutic Method of this major injury and internal fixation apparatus a lot, but final effect is all unsatisfactory.Trace it to its cause, one is that after fractured near end of thighbone, between the broken ends of fractured bone, shearing force and rotation twist stress can not effectively be overcome, and causes between fracture end and is difficult to maintain reset and pressurize fixing; Two is that fractured near end of thighbone is common in again the old people merging osteoporosis in various degree, and multiple internal fixation apparatus is in the past very easily loosening, is difficult to maintain lasting fixed effect, thus causes inefficacy.And the various anatomical plate used at present and Anatomical Proximal Femur Bone Plate and auxiliary screw system thereof have shortcoming in various degree.For making up the deficiency of fractured near end of thighbone treatment means and operating theater instruments, be badly in need of providing a kind of treat near end of thighbone major injury good effect, heal fast apparatus.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of near end of thighbone universal lock steel plate, to overcome the defect of the fixation device used at present.
For solving the problems of the technologies described above, the utility model proposes following scheme: near end of thighbone universal lock steel plate, comprise steel plate and auxiliary screw, described steel plate is curved, with before near end of thighbone, cambered surface that is outer, rear side coincide, and is attached at outside near end of thighbone in parcel shape, the front end of described steel plate is barb, steel plate front portion is followed successively by backward, and steel plate narrowed portion has two any holes; Steel plate widened portion has three temporary fixed holes, three universal lock holes and a dual-purpose hole of universal lock pulling force; The strip parts of steel plate rear portion constriction is divided and is had 6-9 the dual-purpose hole of locking compress, and described auxiliary screw is for hollow, is interior six squares in its tail end; Outer is ball-type screw thread.The front end of auxiliary screw has tapping screw thread.
This utility model also comprises following scheme: have screw thread in described universal lock hole, universal lock hole wall has vertically 3-5 groove, described screw thread is divided into 3-5 section.The described dual-purpose hole of universal lock pulling force is divided into two parts that left and right communicates, and wherein left half is identical with described universal lock hole; Right part is divided into not threaded through hole.The dual-purpose hole of pressurization at described steel plate rear portion is divided into two parts that left and right communicates, and wherein left half is threaded; Right part is divided into not threaded through hole.
Operation principle and the advantage of near end of thighbone universal lock steel plate are:
1, the segmented thread structure in universal lock hole 4 can make auxiliary screw from different perspectives through locking steel plate precession femoral head and neck, tightens rear locking steel plate and is namely connected with steel plate.
2, the dual-purpose hole of universal lock pulling force that steel plate widened portion is opened both also can be screwed into one piece of universal lock screw to neck of femur to lesser trochanter direction, its pulling force bore portion can be screwed into one piece of lag screw to lesser trochanter.
3, the fracture fragment on greater trochanter of femur top can be hooked when the barb 1 of steel plate front end needs, can be cut off when not needing and abandon.
4, two pieces of cancellous bone screws can be screwed in two any holes 2 that steel plate narrowing portion separates, itself and barb can be cut off in the lump when not needing and abandon.
When Fracture of femur is cured, first this near end of thighbone universal lock steel plate is put into outside near end of thighbone, is fixed together with thin Kirschner wire by temporary fixed hole; Again auxiliary screw is chosen angle and be screwed into femoral head and neck by universal hole; Finally the rectangular part of steel plate rear portion constriction is fixed in femoral shaft by the dual-purpose hole of pressurization by common lock screw.
Near end of thighbone universal lock steel plate one plate is multiplex, effectively can fix the multiple fracture of near end of thighbone of fracture, as fracture of femoral neck, intertrochanteric fracture, subtrochanteric fracture etc.
