Abstract
A kind of hip screw lever, be characterized in, hip screw lever has a base plate, and base plate installs an internal stop and an outer baffle block, base plate installs a slideway, slideway is positioned at the opposite of internal stop and outer baffle block, in slideway, install slide block, by the hinged lever of lever bracket on base plate, lever and slide block fit, base plate installs a leading screw by leading screw frame, and leading screw front end withstands on lever, and leading screw rear end is installed and pulled thick stick.The beneficial effects of the utility model are, this hip screw lever is used for being converted into by hip screw in fracture of the femoral head fixation needing angle, its moment is large, bending ability is strong, hip screw can be converted into the arbitrarily angled of needs, the steel pole of hip screw and the skeleton of patient can be made to fit tightly, fixing more solid and reliable.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind ofly hip screw can be converted into the hip screw lever needing angle.
Background technology
After fracture of the femoral head, in femoral head fixing operation, hip screw is usually used to be fixed femoral head, because the angle between everyone femur and femoral head can not be completely equal, so the angle between the steel plate of hip screw and sleeve makes the plurality of specifications such as 125 °, 130 °, 135 °, but still the needs of all patients can not be met.The steel plate of hip screw usually manufactures compare robust, and existing lever is difficult to be converted into the angle adapted with patient, usually needs in some implants of steel plate lower clamping pad during operation, cumbersome when making to perform the operation, and also can affect fixing firmness.
Summary of the invention
For solving the above problems, this utility model provides a kind of hip screw lever, this hip screw lever moment is large, bending ability strong, hip screw can be converted into the arbitrarily angled of needs, the skeleton of the steel plate of hip screw and patient can be made to fit tightly, fix more solid and reliable.
The technical scheme that this utility model technical solution problem adopts is: invent a kind of hip screw lever, be characterized in, hip screw lever has a base plate, base plate installs an internal stop and an outer baffle block, base plate installs a slideway, slideway is positioned at the opposite of internal stop and outer baffle block, in slideway, slide block is installed, by the hinged lever of lever bracket on base plate, lever and slide block fit, base plate installs a leading screw by leading screw frame, and leading screw front end withstands on lever, and leading screw rear end is installed and pulled thick stick.
The beneficial effects of the utility model are, this hip screw lever is used for being converted into by hip screw in fracture of the femoral head fixation needing angle, its moment is large, bending ability is strong, hip screw can be converted into the arbitrarily angled of needs, the skeleton of the steel plate of hip screw and patient can be made to fit tightly, fixing more solid and reliable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Accompanying drawing is the front view of the present embodiment.
1 leading screw in figure, 2 pull thick stick, 3 leading screw framves, 4 base plates, 5 levers, 6 lever seats, 7 slide blocks, 8 slideways, 9 outer baffle blocks, 10 internal stops, 11 hip screws, 12 graduation marks.
Detailed description of the invention
As shown in drawings, base plate 4 is installed outer baffle block 9 and internal stop 10, base plate 4 is installed slideway 8, in slideway 8, slide block 7 is installed, by lever seat 6 hinged lever 5 on base plate 4, base plate 4 installs leading screw 1 by leading screw frame 3, and leading screw 1 front end withstands on lever 5, leading screw 1 rear end is installed and is pulled thick stick 2, and base plate 4 is provided with graduation mark 12.
As shown in drawings, during use, the steel plate of hip screw 11 is placed on outer baffle block 9, between internal stop 10 and slide block 7, make the position alignment slide block 7 needing bending, rotate with hands and pull thick stick 2, leading screw 1 is moved inward, leading screw 1 promotes the axle of lever 5 on lever seat 6 and rotates, promote slide block 7 to move to by the steel plate direction of hip screw 11 in slideway 8, the steel plate promoting hip screw 11 presses to internal stop 10 and outer baffle block 9, at slide block 7, under the effect of internal stop 10 and outer baffle block 9 pressure, the steel plate of hip screw 11 is by bending, the angle of bending can be observed according to graduation mark 12, general larger than the angle folding needed when bending, after loosening leading screw 1, the steel plate of hip screw 11 has a certain amount of resilience, the angle that can reach needs after should making the steel plate resilience of hip screw 11 is advisable.The present embodiment also can place hip screw 11, as required in the opposite direction to the steel plate bending of hip screw 11 by the direction of two-dot chain line in accompanying drawing.
