Abstract
The invention discloses a kind of reamer for hip arthroplasty,acetabulum, it includes the blade that the skeleton that medical stainless steel material is made is made with the medical stainless steel material being arranged on skeleton, described skeleton includes the support bar that at least two is distributed on the same conical surface, blade it is correspondingly arranged respectively on each support bar, described blade is arc, the blade of each blade is arranged on same sphere, and blade is fixing with support bar to be connected.The reamer for hip arthroplasty,acetabulum simple in construction of the present invention, manufacturing cost is significantly cut down, easy to use, and cutting face is highly polished, it is possible to accelerate procedure, improves procedure efficiency and the precision of operation.
Description
Technical field
The present invention relates to medical instruments field, a kind of hip of use when carrying out hip surgery
Mortar is filed.
Background technology
Reamer for hip arthroplasty,acetabulum is to do the medical apparatus and instruments that operation on hip joint is indispensable, and existing reamer for hip arthroplasty,acetabulum is typically spherical structure,
Sphere is provided with multiple circular hole, cutting tooth is set at circular hole, when operation by cutting tooth patient
Being machined away by slough at hip joint, because cutting tooth is Discrete Distribution, cutting face is discontinuous,
Poor flatness, another kind of reamer for hip arthroplasty,acetabulum is to be provided with S-shaped or criss-cross blade, this hip on sphere base body
Being connected by the connection ring of blade end between blade and the base body of mortar file, this connected mode causes blade
Middle part is connected instability with base body, and when reamer for hip arthroplasty,acetabulum uses, blade easily shifts, and causes cutting face to deform,
The precision of impact operation, accordingly, it would be desirable to improve existing reamer for hip arthroplasty,acetabulum.
Summary of the invention
Present invention aims to the cutting face precision of reamer for hip arthroplasty,acetabulum in the prior art described in background technology
Difference, the problem being easily deformed, it is provided that a kind of reamer for hip arthroplasty,acetabulum that can solve the problem that foregoing problems.
The technical scheme of the goal of the invention being capable of the present invention is as follows:
A kind of reamer for hip arthroplasty,acetabulum, it include skeleton that medical stainless steel material makes and be arranged on skeleton medical not
The blade that rust Steel material is made, described skeleton includes the support bar that at least two is distributed on the same conical surface,
Being correspondingly arranged blade on each support bar respectively, described blade is arc, and the blade of each blade is arranged on
On same sphere, blade is fixing with support bar to be connected.
In order to strengthen the bonding strength of blade and support bar, preventing reamer for hip arthroplasty,acetabulum in use, blade is shifted over,
Being provided with slot on described support bar, the bottom of blade is provided with the inserted block corresponding with slot, at slot and
Position corresponding on inserted block is provided with for the through hole through clamping screw.
The cross sectional shape of described slot is T-shaped or trapezoidal, and the cross sectional shape of inserted block is T-shaped or ladder accordingly
Shape.
Described skeleton includes three support bars, and the top welding of each support bar, between each support bar etc.
Spacing is arranged.
Described skeleton includes four support bars, and the top welding of each support bar, each support bar is cross
Shape distribution is arranged.
In order to strengthen the stability of skeleton, prevent skeleton from deforming in use, the precision of impact operation,
The lower end of described support bar is provided with the waling stripe connecting adjacent support bar.
Further, the lower end of described support bar is provided with the horizontal loop connecting each support bar.
The reamer for hip arthroplasty,acetabulum simple in construction of the present invention, manufacturing cost is significantly cut down, easy to use, in use only
Needing to be fixed to blade on skeleton to use, because blade is arc, the blade of each blade is arranged on
On same sphere, therefore, when performing the operation, it is possible to uniformly cut on the hipbone of patient, because blade
For continuous knife blade, so cutting face is highly polished, because being provided with multi-disc blade, so cutting speed is fast,
The speed of operation can be accelerated, improve efficiency, alleviate the misery of patient.
