Abstract
Lockplate on the outside of a kind of undercut mark proximal humerus, including lockplate proximal end, lockplate distal end and plate body, the both ends of plate body are separately connected lockplate proximal end and lockplate distal end, lockplate is distally-oriented to the cambered surface that setting radian in humerus direction does not wait, lockplate distal end corresponds to the cambered surface radian on front side of humerus and is less than the cambered surface radian corresponded on rear side of humerus, when lockplate proximal end is mutually fixed with humerus, lockplate distal end, which passes through cambered surface and humerus, forces lockplate distal end to the displacement of humerus front side with merging, to make lockplate distal end expose under deltoid muscle, lockplate distal end is completed to fix by fixation hole, it rives the modus operandi of approach without the deltoid muscle being completely exposed, reduce operation wound face, reduce the pain of patient, it is also easier to patient's recovery.
Description
Technical field
The utility model relates to the technical field of orthopedic medical device, the outer side chain of specifically a kind of undercut mark proximal humerus
Fixed board.
Background technique
Currently, the fractured near end of humerus is a kind of common fracture, it is common in the osteoporotic fracture of the elderly, is passed through
Chest deltoid muscle approach or deltoid muscle approach surgical treatment proximal humeral fracture of riving are still to cut standard procedures mode fixed in again at present,
But after using chest deltoid muscle approach, the side rear of fracture is exposed there are still certain difficulty, this gives the placement band of interior fixation
Challenge is carried out.
Lockplate on the outside of undercut mark proximal humerus, including lockplate proximal end, locking are generallyd use in the operation of deltoid muscle approach
Plate distal end and plate body, the both ends of plate body are separately connected lockplate proximal end and lockplate distal end, in lockplate proximal end, lockplate distal end
With the continuous cambered surface that unified radian is arranged on plate body, in lockplate and fixed humerus, cambered surface is matched with the surface of humerus, but
The lockplate distal end that is lockplate in the prior art when using fixed can be to deviating on rear side of humerus, to make lockplate distal end
Fixation hole is blocked by deltoid muscle stop, is made troubles for operation, must continue to cutting deltoid muscle just at this time to expand visual area.
Utility model content
The technical problem to be solved by the present invention is to provide lockplates on the outside of a kind of undercut mark proximal humerus.
The utility model is adopted the technical scheme that solve technical problem present in well-known technique:
Lockplate on the outside of the undercut mark proximal humerus of the utility model, including lockplate proximal end, lockplate distal end and plate body,
The both ends of plate body are separately connected lockplate proximal end and lockplate distal end, and lockplate is distally-oriented to what setting radian in humerus direction did not waited
Cambered surface, lockplate distal end corresponds to the cambered surface radian on front side of humerus and is less than the cambered surface radian corresponded on rear side of humerus, in lockplate
When proximal end and humerus are mutually fixed, lockplate distal end, which passes through cambered surface and humerus, forces lockplate distally to humerus front side position with merging
It moves.
The utility model can also use following technical measures:
Sliding eye is set along plate body direction on the plate body.
Fixation hole is respectively set on the lockplate proximal end, lockplate distal end and plate body.
The cambered surface of radian not etc. is all arranged towards humerus direction for lockplate proximal end and plate body, and lockplate distal end corresponds to humerus
The cambered surface radian of front side is less than the cambered surface radian corresponded on rear side of humerus, and when lockplate is mutually fixed with humerus, lockplate passes through
Cambered surface, which matches to merge with humerus, forces lockplate to displacement on front side of humerus.
The utility model has the advantages and positive effects of:
It is different in lockplate distal end setting two sides radian on the outside of the undercut mark proximal humerus of the utility model in lockplate
Cambered surface, thus when lockplate proximal end and humerus are mutually fixed, the distal end of lockplate under the driving of cambered surface to moving on front side of humerus,
To make lockplate distal end expose under deltoid muscle, lockplate distal end is completed to fix by fixation hole, without complete
Exposed deltoid muscle is rived the modus operandi of approach, is reduced operation wound face, is reduced the pain of patient, be also easier to patient
Restore.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of lockplate on the outside of the undercut mark proximal humerus of the utility model；
Fig. 2 is the schematic diagram of the lockplate distal end of lockplate on the outside of the undercut mark proximal humerus of the utility model.
Specific embodiment
The technical solution of the utility model is described in detail below by way of the drawings and specific embodiments.
As depicted in figs. 1 and 2, lockplate on the outside of the undercut mark proximal humerus of the utility model, including lockplate proximal end 1,
Lockplate distal end 2 and plate body 3, the both ends of plate body are separately connected lockplate proximal end and lockplate distal end, it is characterised in that: lockplate
It is distally-oriented to the not equal cambered surface 4 of humerus direction setting radian, lockplate distal end corresponds to the cambered surface radian on front side of humerus and is less than pair
Should be in the cambered surface radian on rear side of humerus, when lockplate proximal end is mutually fixed with humerus, lockplate distal end passes through cambered surface and matches with humerus
Merging forces lockplate distal end to displacement on front side of humerus.
Sliding eye 5 is set along plate body direction on plate body, screw passes through sliding eye connection humerus to pressurize.
Fixation hole 6 is respectively set on lockplate proximal end, lockplate distal end and plate body, screw is each passed through each lock hole will be low
It is mutually fixed on the outside of lockplate and humerus on the outside of incisura proximal humerus.
When lockplate proximal end is mutually fixed with humerus, humerus is easier to the cambered surface side phase for having bigger radian with lockplate distal end
Cooperation, thus make the distal end of lockplate under the driving of cambered surface to moving on front side of humerus, to make lockplate distal end from deltoid muscle
Under expose, lockplate distal end is completed to fix by fixation hole, is rived the hand of approach without the deltoid muscle being completely exposed
Art mode reduces operation wound face, reduces the pain of patient, is also easier to patient's recovery.
The cambered surface of radian not etc. is all arranged towards humerus direction for lockplate proximal end and plate body, and lockplate distal end corresponds to humerus
The cambered surface radian of front side is less than the cambered surface radian corresponded on rear side of humerus, and when lockplate is mutually fixed with humerus, lockplate passes through
Cambered surface, which matches to merge with humerus, forces lockplate to displacement on front side of humerus.
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
Limitation, it is any however, be not intended to limit the utility model although the utility model has been described by way of example and in terms of the preferred embodiments
Those skilled in the art are not departing within the scope of technical solutions of the utility model, certainly can be using in the technology disclosed
Appearance makes a little change or modification, becomes the equivalent embodiment of equivalent variations, but all without departing from technical solutions of the utility model
Content, any simple modification, equivalent change and modification made by the above technical examples according to the technical essence of the present invention,
It is all within the scope of the technical scheme of the utility model.
