Abstract
A kind of fixator with Human Patella shape adaptation is provided, with fixed plate and stripper plate, the fixed plate two ends are provided with symmetrical patella claw, fixed bolt is fixed on dead plate upper end face through fixed plate by nut on the stripper plate, and the patella claw and the upper surface of fixed plate junction are formed with anti-slip veins.The present invention can make patella claw be combined closely with kneecap by the cooperation of bolts and nuts, fixed, reduce fracture gap, and accelerating bone healing is simple in construction, easy to use.
Description
Technical field
The invention belongs to technical field of medical instruments, and in particular to a kind of fixator with Human Patella shape adaptation.
Background technology
Usually require to use patella claw when clinically treating patellar fracture, especially in nursery work, use at present
The overall structure for the integral type that patella claw is typically made of expensive memorial alloy, denaturation adjustment is realized by memorial alloy, is made
Used time needs the free-hand fixation of medical personnel, this free-hand mode for making patella claw be combined closely with kneecap, due to strength very little, and
And gradual pressure can not be carried out so that patella claw can not combine closely with kneecap, and then fracture occur gap is larger shows
As, cause longer the time required to union, pain brought to patient, while have during free-hand pressed, by
It is more smooth in patella claw end face, made troubles in use to medical worker, therefore, it is necessary to be improved.
The content of the invention
Present invention solves the technical problem that：A kind of fixator with Human Patella shape adaptation is provided, can make patella claw with
Kneecap is combined closely, while anti-slip veins are easy to medical personnel to be affectedly bashful fixator, accelerates procedure, simple in construction, easy to use,
The technical solution adopted by the present invention：With the fixator of Human Patella shape adaptation, with fixed plate and stripper plate, institute
Fixed plate two ends are stated provided with symmetrical patella claw, fixed bolt is fixed through fixed plate by nut on the stripper plate
In dead plate upper end face, the patella claw and the upper surface of fixed plate junction are formed with anti-slip veins.
Wherein, three handles are fixed with the outside of the nut and handle is uniformly distributed.
The present invention can make patella claw be combined closely with kneecap by the cooperation of bolts and nuts compared with prior art, fixed
It is firm, reduce fracture gap, accelerating bone healing is simple in construction, easy to use.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Embodiment
1 a kind of embodiment of the invention is described below in conjunction with the accompanying drawings.
With the fixator of Human Patella shape adaptation, with fixed plate 1 and stripper plate 2, the two ends of fixed plate 1 are provided with phase
Fixed bolt 4 is fixed on the upper end of fixed plate 1 through fixed plate 1 by nut 5 on mutual symmetrical patella claw 3, the stripper plate 2
Face, the outside of nut 5 is fixed with three handles 6 and handle 6 is uniformly distributed, when needing pressurization, can rotate spiral shell by handle 6
Mother 5 makes patella claw 3, stripper plate 2 preferably be contacted with kneecap.The upper surface of the patella claw 3 and the junction of fixed plate 1 is formed with anti-
Sliding line 7, prevents medical personnel to be affectedly bashful phenomenon that is unstable and skidding.The outside of nut 5 is fixed with three handles 6 and handle 6 is equal
Even distribution, handle 6 makes to carry out easily and fast during people's adjusting nut 5.
Above-described embodiment, simply presently preferred embodiments of the present invention, not for limiting the scope of the present invention, thus it is all with this
The equivalence changes that content described in invention claim is done, all should be included within scope of the invention as claimed.
Claims (1)
