Abstract
An anatomical internal fixation plate for proximal femur of children comprises an anatomical plate 13 and a straight plate 14, wherein the width of the anatomical plate 13 is wider than the straight plate, and the shape of the anatomical plate 13 is matched with the shape of femur tuberosity. The inclined angle alpha 1 which is formed by the front portion of the anatomical plate and the straight plate is 10-15 degrees, the inclined angle alpha 2 which is composed of the rear portion of the anatomical plate and the straight is 15-25 degrees, and the inclined angle beta which is formed by the central line of the anatomical plate and the central line of the straight plate is 15-20 degrees. Three screw holes 11 which are arranged in a shape or an approximate shape of Chinese character 'pin' are arranged on the anatomical plate, and four longitudinal screw holes 11 are opened on the straight plate. The shape of the anatomical plate on a steel plate of the utility model is matched with the shape of the femur tuberosity, which can be more close to proximal femur of children, firmly and internally fixes fracture, avoids the fixed rotation of fracture and angulation deformity, and largely reduces cure time, thereby relieving pains of children. Compared with the prior art, the utility model has the characteristics of simple operation and convenient employment and the like.
Description
Technical field
This utility model relates to a kind of inner fixing device of orthopedic medical device class, particularly a kind of be applicable under 5-10 year children femoral intertrochanteric fracture, subtrochanteric fracture, the tuberosity rebuild behind the tumor resection, children femoral near-end anatomical form internal fixation steel plate that the orthopedic back of coxa vara osteotomy rebuilds.
Background technology
Fracture of femur is the common type that the child fractures, and femoral bone tuberosity surrounding fracture (intertrochanteric fracture, subtrochanteric fracture) is its treatment difficult point.Present viewpoint is to advocate to pass through expectant treatment, but for multiple fracture, merging craniocerebral trauma, the damage of merging nervus vasculairs and the dissatisfied person of expectant treatment, the treatment that often need undergo surgery, even and for rebuild behind children femoral subtrochanteric fracture, intertrochanteric fracture of the femur, the tumor resection, the orthopedic back of coxa vara osteotomy rebuilds does not have relevant internal fixation product.
At present, domestic main use adult is with reconstruction plate treatment children femoral subtrochanteric fracture, because the adult is the design of non-anatomical form with reconstruction plate, the pre-bending during reconstruction causes that easily armor plate strength loses, fracture line near-end hold-down screw is less, can not reach the requirement of AO internal fixation; AO manufacturer provides in the world be applicable to the orthopedic child of osteotomy under child's tuberosity with the structure of gusset shown in accompanying drawing 6,7, have screw hole 11 longitudinally on the steel plate 1, its tail end has sword plate 12.Its weak point is that the sword plate is too thick, the sword plate is being beaten the damage that increases the weight of easily when entering femur femoral head blood fortune.
Summary of the invention
The purpose of this utility model is the above-mentioned deficiency that overcomes prior art, and a kind of children femoral near-end anatomical form internal fixation steel plate is provided, and it can make fracture reach strong fixing, can reduce the influence to femoral head blood fortune again as far as possible.
The technical solution of the utility model is: a kind of children femoral near-end anatomical form internal fixation steel plate, have screw hole on the steel plate, and it comprises dissects template and straight plate, and the width of dissecting template is wideer than straight plate, and the shape of its shape and femoral bone tuberosity adapts.
The further technical scheme of this utility model is: dissect the front portion of template and the angle α of straight plate formation
1Be 10-15 °, dissect the rear portion of template and the angle α of straight plate formation
2Be 15-25 °, the angle β that dissects the centrage of template and the directly centrage formation of plate is 15-20 °.
This utility model further technical scheme is: dissect the screw hole that has three one-tenth " product " fonts or approximate " product " font to arrange on the template.
This utility model compared with prior art has following characteristics:
1, simple to operate, easy to use, shorten treatment time greatly, thereby alleviated the misery of infant;
2, since shape and the shape of femoral bone tuberosity of the dissection template on the steel plate adapt, can more docile and obedient children femoral near-end, making fractures reaches strong internal fixation, avoids the rotation and the angulation deformity of fracture fixation.
Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.

The specific embodiment
Shown in accompanying drawing 2-5: a kind of children femoral near-end anatomical form internal fixation steel plate, it comprises dissects template 13 and straight plate 14, the thickness of dissecting template 13 and straight plate 14 is 3mm, the width of dissecting template 13 is wideer than the width of straight plate 14, the shape of its shape and femoral bone tuberosity adapts, and dissects the front portion 131 of template 13 and the angle α of straight plate formation that is:
1Be 10-15 °, dissect the rear portion 132 of template 13 and the angle α that directly forms between the plate
2Be 15-25 °, the angle β that dissects the centrage of template and the directly centrage formation of plate is 15-20 °, dissects the screw hole 11 that three one-tenth " product " fonts or approximate " product " font layout are arranged on the template, directly has four screw holes 11 longitudinally on the plate 14.
During use, this utility model is ridden the both sides (as shown in Figure 1) of hip in fracture place 21 of femur, dissect template 13 and be positioned at femoral head 22 1 sides, straight plate 14 is positioned at femoral shaft 23 1 sides, with screw 3 straight plate 14 is fixedly mounted on the femoral shaft 23 then, to dissect template 13 with screw 4,5 is fixedly mounted on the femoral head 22, make the screw 4 that is installed in two oblique screw holes 11 of dissecting above the template 13 epiphyseal plate 24, be installed in screw 5 in the screw hole 11 of dissecting below the template 13 over against the lesser trochanter 25 of femur over against femur.
Children femoral near-end anatomical form internal fixation steel plate, be to rebuild a kind of inner fixing device is provided for reconstruction behind the tumor resection under children femoral subtrochanteric fracture, intertrochanteric fracture of the femur, the tuberosity, the orthopedic back of coxa vara osteotomy, this device is followed the AO principle of fracture fixation, it can make fracture reach strong fixing, minimizing is followed the growth and development characteristics of child's skeleton again and is avoided damaging epiphyseal plate as far as possible the influence of femoral head blood fortune.
