Description
What this utility model femoral interlocking intramedullary nail sight related to is a kind of bone surgery therapeutic device, is specially adapted to the treatment of femoral interlocking intramedullary nail far-end proximal femur fractures.
Present femoral interlocking intramedullary nail near-end sight is assembled into the one insertion by positioning seat, locating rod and is fixed in the handle, aperture apparatus has guide rod in the positioning seat, positioning seat is divided into left and right two different pieces and is not used for left and right sides lower limb Fracture of femur implanted femur intramedullary interlocking nail fracture, this sight uses very inconvenient, and medical personnel need change left and right sides positioning seat and go wrong easily and delay operating time and increase patient's misery when being used for left and right fracture of leg treatment.Existing femoral interlocking intramedullary nail sight is because other parts are many, and complex structure benzene heavily uses very hard.
The purpose of this utility model is to exist weak point that a kind of novel femoral interlocking intramedullary nail sight is provided at present femoral interlocking intramedullary nail sight, adopt new construction proximally-located bar to replace original positioning seat, positioning rod component, guide rod has assembles guide rod about a plurality of inclined-planes can be distinguished, be used for left and right sides lower limb Fracture of femur treatment, this sight is reasonable in design, and is simple in structure, light and handy, easy to use, the aiming accurate positioning can be shortened operating time and reduce patient's misery.
The femoral interlocking intramedullary nail sight takes following scheme to realize: the sight primary structure is made of handle, proximally-located bar, guide rod, locating rack, locating rod, connecting screw rod, positioning sleeve.Proximally-located bar one end dress is inserted and is fixed on the handle upper end, the proximally-located bar other end has guide rod by the alignment pin fixture, and proximally-located bar one end is provided with square body, positioning stablity, be provided with symmetrical inclined-plane about the other end, make formation inclined-plane, guide rod assembling back and femoral interlocking intramedullary nail arc tangent.The guide rod near-end is provided with several incline benches, locating hole, pinching screw hole, distal locking nail locating hole, and the guide rod far end device has locating rack, is fixed with locating rod by clamp on the locating rack.End device has positioning sleeve under the handle, and dress is inserted with connecting screw rod in the positioning sleeve, is used for fixing femoral interlocking intramedullary nail, and the positioning sleeve front end has fixed cover.
The femoral interlocking intramedullary nail sight is owing to be provided with the proximally-located bar on symmetrical inclined-plane about adopting, can about the proximally-located bar, assemble guide rod respectively, be used for left and right sides lower limb Fracture of femur treatment, guide rod is easy to assembly, reduced positioning seat, alleviated weight greatly,, made formation inclined-plane, guide rod assembling back and femoral interlocking intramedullary nail arc tangent correct to guarantee the far-end location because the proximally-located bar is provided with symmetrical inclined-plane.This utility model sight is reasonable in design, and is simple in structure, and good looking appearance is light and handy, easy to use, and the operation process clamping aiming time accurately can be shortened greatly in the aiming location, alleviates patient's misery so that shorten operating time.
The utility model is described in further detail below with reference to accompanying drawing.
