Abstract
The utility model relates to a sliding weight intramedullary broacher, which is characterized in that a thick slide bar at the far end is arranged through a sliding weight broacher and the slide bar and connected with a handlebar. The sliding weight intramedullary broacher has the advantages of reasonable structure, simple operation, and ability to effectively guide the bone grafting direction, tamp the bone grafting material and enable the medullary cavity shape of the repaired part to be fitted with the thighbone prosthesis.
Description
Technical field
This utility model relates to a kind of sliding hammer pulp cavity file, particularly a kind of sliding hammer pulp cavity file that is used for orthopaedics compacting bone-grafting material.
Background technology
For unstructuredness or the structural allograft, bone grafting in the pulp cavity of rebuilding behind original loosening rear pulp cavity that enlarges and the structural bone grafting, mostly adopt universal Myelocavity file compacting graininess plant bone mass, the graininess plant bone mass moved and tamped situation from poor effect to the pulp cavity far-end occurs so easily.At present, lack a kind of apparatus that the femur side prosthesis is overhauled bone grafting, compacting bone-grafting material, operating process simple possible that is used for.
Summary of the invention
The purpose of this utility model is at above-mentioned drawback, and a kind of sliding hammer pulp cavity file of being convenient to install the femoral prosthesis that adapts with it after shape is similar to universal pulp cavity file, compacting graininess plant bone mass is definite, compacting is shaped that has is provided.The slide bar of this sliding hammer formula Myelocavity file has different specifications, can be complementary with the far-end pulp cavity, can prevent effectively that the graininess plant bone mass from moving to the pulp cavity far-end.Because itself and far-end pulp cavity are complementary, be used with the sliding hammer file with chute, can effectively guide the bone grafting direction, prevent from turning in the femoral prosthesis implantation afterwards or turning up, kept good collodiaphyseal angle.
A kind of sliding hammer formula Myelocavity file described in the utility model is characterized in that: have the thicker slide bar of a far-end to pass the sliding hammer file and sliding hammer is connected with handgrip.
The chute of sliding hammer file described in the utility model can be round hole type or triangle culvert shape or square culvert shape; The surface of sliding hammer file can be smooth or vertical stripe shape or prismatic or stairstepping; The top of sliding hammer file is provided with one and controls bar; The surface of slide bar far-end thicker part position can be smooth or vertical stripe shape, and the slide bar middle part is thin and sliding hammer is filed and sliding hammer is complementary, and the slide bar near-end is detachable with being connected of handle; Sliding hammer can be the cylindricality sliding hammer, and cylindricality sliding hammer far-end carefully and with sliding hammer file dorsal part adapts, and cylindricality sliding hammer near-end is thicker, can be cylindrical or square column type; Sliding hammer can be the V shape sliding hammer, and bifurcation and the slide bar of V shape sliding hammer are complementary.
The beneficial effects of the utility model are, being applied to unstructuredness or structural bone transplants, to rebuilding the bone grafting in the pulp cavity behind original loosening back pulp cavity that enlarges and the structural bone grafting, can be by the sliding hammer pulp cavity file of the specification that varies in size, around gradually plant bone mass being pushed to, guaranteed the compacting of graininess plant bone mass, and the pulp cavity shape that adapts of formation and femoral prosthesis.The nearly lesser trochanter side in sliding hammer file upper end has a steering yoke, has guaranteed good top rake.

Among the figure: 1. slide bar, 2. band steering yoke sliding hammer file, 3. cylindricality sliding hammer, 4. handgrip, 5. V shape sliding hammer, 6. slide bar far-end thicker part position, 7. the sliding hammer file is not with steering yoke.
The specific embodiment
A kind of sliding hammer pulp cavity file described in the utility model as Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8 and shown in Figure 9, has the thicker slide bar of a far-end 1 to pass the sliding hammer of the sliding hammer file 2 of band steering yoke and cylindricality 3 be connected with handgrip 4 (as Fig. 1).As shown in Figure 2, sliding hammer can be V shape sliding hammer 5, and bifurcation and the slide bar of V shape sliding hammer are complementary.As shown in Figure 3, the sliding hammer file is not with steering yoke 7.Among the above embodiment, the chute of sliding hammer file is round hole type; Sliding hammer file smooth surface; The smooth surface of slide bar far-end thicker part position 6; The slide bar middle part carefully and with sliding hammer file and sliding hammer is complementary; Being connected to of slide bar near-end and handle is detachable.This utility model is rational in infrastructure, and is simple to operate, can effectively guide the bone grafting direction, and the compacting bone-grafting material makes the reparation position reach the pulp cavity shape that adapts with femoral prosthesis.
