Abstract
The invention relates to an acetabular bone file which is suitable for a bone joint replacement surgery. Under the driving a power tool, a physical acetabular bone is filed to form an accurate predicated shape (semi-spherical shape or frustum shape), so that an acetabular bone planted object is convenient to plant. The acetabular bone file is composed of a cutting main body and a rapid replacement part, wherein the rapid replacement part is fixedly connected with the cutting main body; the cutting main body is a dome-shaped thin shell; a plurality of convex cutting edges are irregularly distributed on the outer surface of the thin shell; each cutting edge is provided with a scrap containing hole; the length direction of each scrap containing hole is vertical to the corresponding cutting edge; the cutting edge parts are parallel to the outer surface of the dome-shaped thin shell. The plurality of convex cutting edges are distributed at all parts of the predicated formed shape. The lengths of one part of the cutting edges parallel to the outer surface of the dome-shaped thin shell is not less than 0.5mm. The wall thickness of the cutting main body is not more than 3mm. The rapid replacement part is a cross-shaped bracket or in a disc shape with holes.
Description
Technical field
What the present invention relates to is a kind of reamer for hip arthroplasty,acetabulum, is applicable to orthopaedics joint replacement surgery, and under power tool drives, the shape (hemispherical or taper type) that physiology acetabular bone becomes accurately expection repaiied by file, is convenient to Cotyloid implant and implants.
Background technology
Current reamer for hip arthroplasty,acetabulum is the overall file adopting the hemispherical hip of multi-blade usually, and spherical substrate is inlaid with some straight or screw type blades, and this design torque is comparatively large, and bone collects difficulty, and the need filing the spherical hip accomplished are cleared up further.The another kind of reamer for hip arthroplasty,acetabulum entirety improved adopts shell structure, the semicircle shape of protrusion is wherein had to cut pin tooth, and with appearance bits hole, this design once cannot become expection accurate shape along cut direction, weak point is complicated operation, and form accuracy is poor, higher to operator's operation, be difficult to grasp.
Summary of the invention
The present invention seeks to provide a kind of reamer for hip arthroplasty,acetabulum for above-mentioned weak point, adopt shell dome type structure, drive part is designed with accurate quick change parts, and cutting edge is irregular to be distributed in outside dome shape shell, and it is convex, protruding effective cutting edge, be parallel to shell appearance and have certain length, cutting accuracy is high, and along cutting direction Accurate Shaping, be convenient to implant implant by expection object, stock-removing efficiency is high, and bone is collected complete.Owing to being designed with the accurate quick change construction just accurate quick-replaceable of operator, the reamer for hip arthroplasty,acetabulum of different size carries out repeatedly acetabular bone shaping by stock removal, and the shape of expection accomplished by final file.
Reamer for hip arthroplasty,acetabulum realizes by the following technical solutions:
Reamer for hip arthroplasty,acetabulum is made up of cutter body, quick change parts.Quick change parts are fixedly connected with bottom cutter body.Cutter body is dome shape shell, and at the irregular cutting edge being distributed with several projections of shell outer surface, the cutting edge of several projections is dispersed throughout the shape of expecting everywhere.Each cutting edge holds bits hole with one, holds the length direction in bits hole perpendicular to cutting edge.Cutting edge part is parallel to dome shape shell outer surface.Be parallel to dome shape shell outer surface part cutting edge length and be not less than 0.5mm.
Cutting edge part is parallel to dome outer surface part cutting edge length and is not less than 0.5mm.
Described cutter body wall thickness is not more than 3mm.
Described quick change parts are cross bracket or disc with holes.
Operation principle:
Reamer for hip arthroplasty,acetabulum uses in hip replacement surgery, during use, reamer for hip arthroplasty,acetabulum is arranged on reamer for hip arthroplasty,acetabulum extension bar one end by quick change parts, the reamer for hip arthroplasty,acetabulum extension bar other end is connected with electric tool, electric tool drives reamer for hip arthroplasty,acetabulum extension bar to drive reamer for hip arthroplasty,acetabulum rotary cutting physiology acetabular bone to become anticipated shape (hemispherical or taper type), be convenient to Cotyloid implant implant, meanwhile reamer for hip arthroplasty,acetabulum can collect whole bone bits, for operator's desired use by holding bits hole.
Reamer for hip arthroplasty,acetabulum of the present invention is reasonable in design, compact conformation, because reamer for hip arthroplasty,acetabulum adopts shell dome type structure, drive part is designed with accurate quick change parts, cutting edge is irregular to be distributed in outside dome shape shell, and convex, protruding effective cutting edge, be parallel to shell appearance and have certain length, cutting accuracy is high, and along cutting direction Accurate Shaping, is convenient to implant and implants by expection object, stock-removing efficiency is high, and bone is collected complete.Owing to being designed with the accurate quick change construction just accurate quick-replaceable of operator, the reamer for hip arthroplasty,acetabulum of different size carries out repeatedly acetabular bone shaping by stock removal, and the shape (hemispherical or taper type) of expection accomplished by final file, is convenient to Cotyloid implant and implants.
