Abstract
The invention discloses an acetabulum file. The acetabulum file comprises a framework and blades, wherein the framework is made of medical stainless steel material, and the blades are arranged on the framework and made of medical stainless steel material. The framework comprises at least two supporting rods which are distributed on a same conical surface. One blade is correspondingly arranged on each supporting rod, the blades are of an arc shape, cutting edges of the blades are arranged on a same spherical surface, and the blades and the supporting rods are fixedly connected. The acetabulum file is simple in structure and convenient to use, smoothness of a cutting face is high, manufacturing cost is greatly lowered, the operation process can be quickened, and operation efficiency and operation accuracy can be improved.
Description
Technical field
The present invention relates to medical instruments field, particularly a kind of reamer for hip arthroplasty,acetabulum of use when carrying out hip surgery.
Background technology
Reamer for hip arthroplasty,acetabulum is the medical apparatus and instruments of doing operation on hip joint indispensability, existing reamer for hip arthroplasty,acetabulum is spherical structure normally, on sphere, be provided with a plurality of circular holes, at circular hole, place arranges cutting teeth, when operation, by cutting teeth, at patient's hip joint place, slough is machined away, because cutting teeth is Discrete Distribution, so cutting face is discontinuous, poor flatness, another kind of reamer for hip arthroplasty,acetabulum is on sphere base body, to be provided with S shape or criss-cross blade, connecting ring by blade end between the blade of this reamer for hip arthroplasty,acetabulum and base body is connected, this connected mode causes the middle part of blade to be connected unstable with base body, when reamer for hip arthroplasty,acetabulum is used, blade is easily shifted, cause cutting face distortion, the precision of impact operation, therefore, need to improve existing reamer for hip arthroplasty,acetabulum.
Summary of the invention
The object of the invention is to the cutting face low precision for reamer for hip arthroplasty,acetabulum in the prior art described in background technology, hold yielding problem, a kind of reamer for hip arthroplasty,acetabulum that can solve foregoing problems is provided.
The technical scheme that can realize goal of the invention of the present invention is as follows:
A kind of reamer for hip arthroplasty,acetabulum, it comprises the skeleton that medical stainless steel material is made and is arranged on the blade that the medical stainless steel material on skeleton is made, described skeleton comprises at least two support bars that are distributed on the same conical surface, on each support bar, correspondence arranges blade respectively, described blade is arc, the blade of each blade is arranged on same sphere, and blade is fixedly connected with support bar.
In order to strengthen the bonding strength of blade and support bar, prevent reamer for hip arthroplasty,acetabulum in use, blade is shifted, and on described support bar, is provided with slot, the bottom of blade is provided with the inserted block corresponding with slot, and on slot and inserted block, corresponding position is provided with for the through hole through clamping screw.
The cross sectional shape of described slot is T shape or trapezoidal, and the cross sectional shape of inserted block is T shape or trapezoidal accordingly.
Described skeleton comprises three support bars, the top welding of each support bar, spaced set between each support bar.
Described skeleton comprises four support bars, the top welding of each support bar, and each support bar is crossing distribution setting.
In order to strengthen the stability of skeleton, prevent that skeleton from deforming in use, the precision of impact operation, the lower end of described support bar is provided with the waling stripe that connects adjacent support bar.
Further, the lower end of described support bar is provided with the horizontal loop that connects each support bar.
Reamer for hip arthroplasty,acetabulum of the present invention is simple in structure, and manufacturing cost is significantly cut down, easy to use, only blade need to be fixed on skeleton and can use in use, because blade is arc, the blade of each blade is arranged on same sphere, therefore,, when performing the operation, can on patient's hipbone, evenly cut, because blade is continuous knife blade, so cutting face is highly polished, because be provided with multi-disc blade, so cutting speed is fast, can accelerate the speed of operation, raise the efficiency, alleviate patient's misery.
