Abstract
The utility model discloses a dissection locking plate special for femur medial malleolus fracture. The dissection locking plate comprises a locking plate body, wherein a smooth arc which is adaptive to a physiological radian of the femur medial malleolus is arranged at the edge of the locking plate body, the locking plate body comprises a first fixation portion and a second fixation portion, the first fixation portion and the second fixation portion are arranged on two sides of a fracture line respectively, the outer edge of the first fixation portion is provided with a row of rear locking screw holes for fixing the plate body on the subchondral bone, a plurality of intermediate locking screw holes are formed in the first fixation portion, and a plurality of front locking screw holes are formed in the second fixation portion. According to the dissection locking plate special for femur medial malleolus fracture, the locking plate is closely attached to the femur medial malleolus to achieve effects of strengthening inner fixation.
Description
Technical field
This utility model relates to technical field of medical instruments, especially relates to a kind of dissection locking steel plate that is exclusively used in condylar fracture in femur.
Background technology
In femur, condylar fracture is comparatively common a kind of classification of fracture, current clinical a kind of special steel plate for condylar fracture in femur that there is no.Current for this type of fracture, conventionally by application metaphysis steel plate, it is fixed.But metaphysis steel plate is applied to condylar fracture in femur and has following defect: 1. steel plate is longer, need to make long otch in order to lay steel plate, and large to patient's wound, scar after the operation is large; 2. the shape of the interior condyle portion of this steel plate is not complete interior condyle anatomical shape, and it accounts for interior condyle middle body; Fixed form is the several lock holes of interior condyle central authorities, and this position is mainly spongy bone, can not ensure fixedly securing of this type of fracture, usually causes interior fixing failure.
Utility model content
Technical problem to be solved in the utility model is: a kind of dissection locking steel plate that is exclusively used in condylar fracture in femur is provided, condyle in locking steel plate and femur is closely affixed, reach strong interior fixing effect.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of dissection locking steel plate that is exclusively used in condylar fracture in femur, comprise locking steel plate body, the edge of described locking steel plate body be provided with femur in the suitable round and smooth camber line of condyle physiologic radian, described locking steel plate body has the first fixed part and the second fixed part, described the first fixed part and the second fixed part are arranged at respectively the both sides of fracture line, the outward flange of described the first fixed part is provided with a row for described locking steel plate body being fixed on to the rear portion screw hole of subchondral bone, if the inward flange of described the first fixed part is provided with individual middle screw hole, if described the second fixed part is provided with individual anterior screw hole.
Preferably, the quantity of described rear portion screw hole is five or six, and described in each, the diameter of rear portion screw hole is 2.5mm.
Preferably, the quantity of described middle screw hole is two, and described in each, the diameter of middle screw hole is 4.5mm.
Preferably, the quantity of described anterior screw hole is four, and described in each, the diameter of anterior screw hole is 4.5mm.
Adopted technique scheme, the beneficial effects of the utility model are:
1. this steel plate is special in the fixing steel plate of condylar fracture in femur.
2. steel plate meets the dissection of condyle in normal femur completely, and steel plate attaching property is good.
3. the quantity of rear portion screw hole is five or six, and described in each, the diameter of rear portion screw hole is 2.5mm, and these nail holes can ensure that screw is close to subchondral bone, and the sclerotin intensity of subchondral bone is larger, can reach and fixedly secure.
4. rear portion screw hole, middle screw hole and anterior screw hole are screwed into respectively to lock screw, make it with the femur of fracturing in condyle be fixed together, reach strong interior fixing effect.
Brief description of the drawings
Fig. 1 is the structural representation of this utility model embodiment;
Wherein: 1, locking steel plate body; 2, the first fixed part; 3, the second fixed part; 4, rear portion screw hole; 5, middle screw hole; 6, anterior screw hole; 7, fracture line.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further illustrated.
As shown in Figure 1, a kind of dissection locking steel plate that is exclusively used in condylar fracture in femur, comprise locking steel plate body 1, the edge of locking steel plate body 1 be provided with femur in the suitable round and smooth camber line of condyle physiologic radian, locking steel plate body 1 has the first fixed part 2 and the second fixed part 3, the first fixed part 2 and the second fixed part 3 are arranged at respectively the both sides of fracture line 7, the outward flange of the first fixed part 2 is provided with a row for locking steel plate body 1 being fixed on to the rear portion screw hole 4 of subchondral bone, if the inside of the first fixed part 2 is provided with individual middle screw hole 5, if the second fixed part 3 is provided with individual anterior screw hole 6.
In the present embodiment, the quantity of rear portion screw hole 4 is five or six, and the diameter of each rear portion screw hole 4 is 2.5mm.The quantity of middle screw hole 5 is two, and in the middle of each, the diameter of screw hole 5 is 4.5mm.The quantity of anterior screw hole 6 is four, and the diameter of each anterior screw hole 6 is 4.5mm.
Its operating procedure is as follows:
1, locking steel plate body 1 is positioned over to condyle in femur, the interior condyle of locking steel plate body 1 and femur is closely affixed.
2, rear portion screw hole 4, middle screw hole 5 and anterior screw hole 6 are holed, are screwed into lock screw, make it with the femur of fracturing in condyle be fixed together, thereby complete fixing to condyle in fracture femur.
This dissection locking steel plate can make condyle in locking steel plate and femur closely be affixed, and many pieces of lock screw are implanted, and reach strong interior fixing effect.
This utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done, within all dropping on protection domain of the present utility model.
