Description
Technical field
The present invention relates to a kind of shoulder joint prosthesis, particularly relate to a kind of assembly type shoulder joint prosthesis.
Background technology
Shoulder joint is joint the most flexibly in health, and the major function of shoulder joint is motion, and support gravity and only account for secondary, joint capsule is very lax, and the glenoid articular surface of scapula is very little, very shallow, and this structure makes the motion of head of humerus have very large motility.Shoulder joint is typical ball-and-socket joint, its motion point flexing, stretching, extension, abduction, adduction, outward turning and inward turning.As shown in Figure 1, existing shoulder joint prosthesis is mostly monoblock type shoulder joint prosthesis, is made up of head of humerus 11 and humerus handle 12.
Existing shoulder joint prosthesis mainly has the following disadvantages:
1) head of humerus of existing shoulder joint and humerus handle are structure as a whole, head of humerus and humerus handle have corresponding proportionate relationship, the little head of humerus of pulp cavity is just little, thus, suitable prosthese can not be selected according to the pulp cavity of reality, head of humerus in operation, such as, head of humerus is larger but the thick pulp cavity of cortical bone is little, can only use small size head of humerus in operation.
2) revision procedure or preoperative analysis inconsiderate time, cause embarrassment to doctor, more painful operating time length brought to patient.
3) because prosthese can not be applicable to various disease conditions, preoperative prudent analysis is needed, if analyze not comprehensive, can to the consequence of bringing on a disaster property of patient.
4) existing shoulder joint prosthesis can not accomplish humerus patient with bone disease and humeral fracture patient all applicable.
Summary of the invention
The object of the present invention is to provide a kind of applied widely, easy to operate, practical assembly type shoulder joint prosthesis.
For achieving the above object, the concrete technical scheme of assembly type shoulder joint prosthesis of the present invention is as follows:
A kind of assembly type shoulder joint prosthesis, comprise head of humerus and humerus handle, the end of humerus handle is formed with installed surface, and head of humerus is arranged on the installed surface of humerus handle forward or backwards, for removably connecting between head of humerus and humerus handle.
The advantage of assembly type shoulder joint prosthesis of the present invention is as follows:
1) head of humerus and humerus handle make assembling structure, and head of humerus can use with the assembly of Multiple Type humerus handle.
2) prosthese is applicable to osteopathia, fracture, does and just puts operation or the operation that is inverted, overhaul humerus handle when doing full shoulder joint prosthese and need not take out replacing again according to different situations.
3) head of humerus outer surface is curved, can reduce shearing force, and protection surrounding soft tissue, head of humerus eccentric setting, better covers anatomical neck, realizes double locking mechanism.
4) head of humerus does angle 125-140 degree, the center of rotation moving joint outside humeral shaft can be made outward not move, thus contribute to the normal anatomy tension force of replying shoulder tissue sleeve.
5) take on broad-mouthed receptacle for holding liquid surface curved, the shear stress causing shoulder broad-mouthed receptacle for holding liquid to rock can be converted into the compressive stress making shoulder broad-mouthed receptacle for holding liquid stable.
6) humerus handle near-end is formed with snakelike flank, anti-rotation, be conducive to fracture rebuild.
Accompanying drawing explanation
Fig. 1 is the front view of existing shoulder joint prosthesis;
Fig. 2 is the structural representation of the first embodiment of assembly type shoulder joint prosthesis of the present invention;

Detailed description of the invention
In order to better understand object of the present invention, structure and function, below in conjunction with accompanying drawing, further detailed description is done to a kind of assembly type shoulder joint prosthesis of the present invention.
As shown in Figures 2 and 3, assembly type shoulder joint prosthesis of the present invention comprises head of humerus 20 and humerus handle 30, and wherein, the end of humerus handle 30 is formed with installed surface 31, head of humerus 20 is arranged on the installed surface 31 of humerus handle 30 forward or backwards, for removably connecting between head of humerus 20 and humerus handle 30.Thus, the head of humerus in the present invention and humerus handle make assembling structure, can any model assembly use; But also can according to different situations do just put operation or the operation that is inverted, overhaul humerus handle when doing full shoulder joint prosthese and need not take out replacing again.
As shown in Figure 2, it is the first embodiment in the present invention.In the present embodiment, the installed surface 31 of humerus handle 30 end is formed with columnar protrusions 32, the rear portion of head of humerus 20 is formed with mounting groove 21, and the columnar protrusions 32 on humerus handle 30 is pluggable in the mounting groove 21 on head of humerus 20, is arranged on the installed surface 31 of humerus handle 30 to make head of humerus 20 forward.In addition, the centrage that the mounting groove 21 at head of humerus 20 rear portion in the present embodiment departs from head of humerus 20 is arranged, and deflection head of humerus 20 side upward after installing, thus, the design of head of humerus bias, better covers anatomical neck, double locking mechanism.
Further, the both sides of the columnar protrusions 32 on the installed surface 31 of humerus handle 30 are provided with trip bolt 33, the both sides correspondence of the mounting groove 21 at head of humerus 20 rear portion is formed with fastener hole 22, and the trip bolt 33 on humerus handle 30 can be fixedly connected in the fastener hole 22 on head of humerus 20.
As shown in Figure 3, it is the second embodiment in the present invention.In the present embodiment, the installed surface 31 of humerus handle 30 end is provided with glenoid cavity 40, the end face of glenoid cavity 40 is formed with glenoid fossa 41, head of humerus 20 oppositely be located in the glenoid fossa 41 in glenoid cavity 40 and also can rotate in glenoid fossa 41, is oppositely arranged on the installed surface 31 of humerus handle 30 to make head of humerus 20.
Further, glenoid cavity 40 comprises the tray member 42 and holder backing member 43 that snap together, tray member 42 contacts with the installed surface 31 of humerus handle 30 end, and the end face of holder backing member 43 is formed with glenoid fossa 41, and head of humerus 20 oppositely be located in the glenoid fossa 41 on holder backing member 43.In addition, the installed surface 31 of humerus handle 30 end is formed with columnar protrusions 32, tray member 42 and holder backing member 43 are formed with installing hole 44, the columnar protrusions 32 on humerus handle 30 is pluggable in the installing hole 44 in tray member 42 and holder backing member 43.
Further, the rear portion of head of humerus 20 is provided with shoulder broad-mouthed receptacle for holding liquid 50, and shoulder broad-mouthed receptacle for holding liquid 50 is fixed on head of humerus 20 by screw 51, curved and be formed with the bone cage 52 be fixed with pressure with scapula away from the side of head of humerus 20 on shoulder broad-mouthed receptacle for holding liquid 50.Thus, the shear stress causing shoulder broad-mouthed receptacle for holding liquid to rock can be converted into the compressive stress making shoulder broad-mouthed receptacle for holding liquid stable by the shoulder broad-mouthed receptacle for holding liquid back side cambered design in the present invention.
