Description
Technical field
This utility model relates to medical artificial joint system, particularly relates to a kind of inverted shouldejoint broad-mouthed receptacle for holding liquid
Prosthese.
Background technology
Caput humeri necrosis, proximal humerus serious splintered fracture, Glenohumeral joint inflammation are common clinicals, shoulder
Joint replacement is ultimate treatment means.When this type of is sick and wounded be associated with rotator cuff injury or replacement after need to carry out
When overhauling, half traditional shoulder or full shoulder joint displacement cannot meet the demand for the treatment of.Can only select clinically
Inverted shoulder joint system is performed the operation or overhauls.Due to anatomical reason, glenoid cavity small volume,
And this type of patient has osteoporosis, bone mass to decline or with Cranial defect in various degree, glenoid cavity more
Prosthese bears again the effect of shear stress, and prosthetic loosening, unstability easily occurs in Post operation.Existing market is existing
The inverted shoulder joint prosthesis system having, postoperative the most easily generation mortar cup clashes into scapula lower edge, enters one
Step aggravation glenoid cavity side prosthesis loosens, and causes operative failure.
Increasing fixing screw number to reaching increase glenoid cavity stability in glenoid cavity is the most common hands
Art method, but glenoid cavity finite volume, and the sclerotin declining bone mass, simple increasing fixes screw number
Amount is unable to reach the effect increasing stability.Additionally change the collodiaphyseal angle of mortar cup prosthesis or increase prosthese bias
Away from being also to reduce scapula to clash into and the thinking of prosthetic loosening, but actual effect is little.
Utility model content
For existing inverted shoulder joint displacement system exist be easily generated scapula clash into and prosthetic loosening lack
Falling into, main purpose of the present utility model is: provide a kind of inverted shouldejoint broad-mouthed receptacle for holding liquid prosthese, to solve

Shape, radian is 210-270 degree.
Wherein, in above-mentioned inverted shouldejoint broad-mouthed receptacle for holding liquid prosthese, described glenoid cavity base is formed as round
Column.
Wherein, in above-mentioned inverted shouldejoint broad-mouthed receptacle for holding liquid prosthese, described glenoid cavity bulb and glenoid cavity
Base forms as one formula structure.
Have employed technique scheme, the beneficial effects of the utility model are:
In glenoid cavity bulb design aspect, traditional glenoid cavity bulb many employings semi-circular design, this practicality
Knuckle broad-mouthed receptacle for holding liquid bulb uses big cambered design, adds the shock space of mortar cup and scapula, it is to avoid shoulder
Shoulder blade clashes into.It addition, under equal conditions, the glenoid cavity bulb of selection of small diameter is obtained with same
The prosthese eccentric throw of sample, alleviates glenoid shear stress.This utility model glenoid cavity base and joint
Broad-mouthed receptacle for holding liquid is fixed screw and is preferably fixed optimum position and the angle of screw according to glenoid anatomical features, in conjunction with lock
Determine the angle stability of screw, make glenoid prostheses obtain more stable property and fix.
Therefore, this utility model glenoid prostheses avoid scapula clash into, reduce prosthese shear stress,
Increase prosthese stability aspect all to have a distinct increment, be worth promoting the use of in shoulder joint displacement field.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, make to retouch the most in detail to detailed description of the invention of the present utility model
State.Following example are used for illustrating this utility model, but can not be used for limiting scope of the present utility model.
Fig. 1 is the structural representation of the inverted shouldejoint broad-mouthed receptacle for holding liquid prosthese of this utility model embodiment；Fig. 2
For the structural representation of glenoid cavity base in Fig. 1.
As shown in Figure 1 to Figure 2, the inverted shouldejoint broad-mouthed receptacle for holding liquid prosthese of this utility model embodiment includes:
Glenoid cavity bulb 1, glenoid cavity base 2 and glenoid cavity fixture 3, one end of glenoid cavity base 2 and joint
Broad-mouthed receptacle for holding liquid bulb 1 connects, and the other end of glenoid cavity base 2 is connected with glenoid cavity fixture 3.
Glenoid cavity bulb 1 uses big cambered design, and radian is 210-270 degree, preferably 270 degree, relatively
Traditional glenoid cavity bulb prosthese is compared, and on the one hand adds the eccentric throw of prosthese, increases mortar cup and shoulder
The shock space of shoulder blade, thus decrease the possibility that scapula clashes into, on the other hand, use small diameter
Bulb prosthese be obtained with equal prosthese eccentric throw, the shear stress of glenoid prostheses reduces, and subtracts
The possibility that few glenoid prostheses loosens.Glenoid cavity bulb 1 and glenoid cavity base 2 in the present embodiment are formed
For integral type structure.
Glenoid cavity fixture 3 includes: upper locking fixture 4, centre-lock fixture 5 and the next locking
Fixture 6.Wherein, centre-lock fixture 5 is positioned at the center of glenoid cavity fixture 3, uplock
Determine fixture 4 and the next locking fixture 6 lays respectively at the both sides of centre-lock fixture 5 and forms 150
Degree.Glenoid cavity base 2 is formed as cylindric, and this glenoid cavity base 2 is provided with corresponding upper locking respectively
Fixture 4, centre-lock fixture 5 and the next the locking upper locking fixing hole 7 of fixture 6, center
Locking fixing hole 8 and the next locking fixing hole 9.Upper locking fixing hole 7 is positioned at 12 o'clock position, for
Diameter 3.5mm screw lock hole, locking direction coronalplane, upwards in 35-45 degree, preferably 40 degree, loses
Shape towards front 40-50 degree, preferably 45 degree；Screw hole centered by centre-lock fixing hole 8, for
Diameter 4.5mm screw lock hole, locking direction is vertical with base；The next locking fixing hole 9 is positioned at 7 points
