Abstract
The invention discloses a glenoidal cavity lateral prosthesis, which is characterized by the following: forming the outline of the prosthesis as kidney shape; arranging screw hole on the prosthesis to fix screw; setting the thickness of the prosthesis thin layer less than 5mm; choosing the screw as double tabernacle screw; setting the tabernacle screw as hollow structure; arranging the screw hole on each one-third position of the surface of the prosthesis; designing the inner core as hexagon; setting the thickness of the thin layer less than 5 mm when using; decreasing loss of subchondral bone on the one side of the prosthesis.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, refer in particular to a kind of shoulder joint cavema side prosthesis.
Background technology
Because the ossa articularia amount of shoulder joint cavema side is seldom relatively, and scapula is again special poor, and its special construction just all has higher requirement for the fixed form and the dissection adaptability of the broad-mouthed receptacle for holding liquid side part prosthese of shoulder joint prosthesis.And all there are some problems in existing many designs, such as: fixedly during cavema side prosthesis,, be to be cost with a large amount of glenoid cavity bone amounts of losing in order to reach sufficient fixation, the loosening rate of prosthese is very high as a result, to such an extent as to carry out revision procedure soon; The dissection adaptability that has plenty of cavema side prosthesis is not enough, can not bear the active force of humerus side, has perhaps produced and has not met biokinetic active force, causes to have occurred tangible wearing and tearing or loosening behind the prosthetic replacement more for a long time.So the design of cavema side prosthesis is the difficult problem of shoulder joint prosthesis design field always.Though, the present cavema side prosthesis design that the comparison success is arranged in the world, all incompatible with Chinese body constitution, anatomical features and motor function requirement, and cost an arm and a leg, most patient can not used.The import prosthese that uses at home much is external obsolete product at present, and clinical effectiveness is very limited.
Though existing cavema side prosthesis is fixed in metal holder both sides a screw hole respectively is set, particular locations of unqualified screw hole all, in operating process, existing does not have unified standard, random big and fixing unsettled defective.
Summary of the invention
Purpose of the present invention mainly is to provide a kind of shoulder joint cavema side prosthesis, and it can overcome existing prosthese defective, can preserve the bone amount, early stage good stability; Make it have good anti-revolving and stability.
In order to achieve the above object, the technical solution adopted in the present invention is: a kind of shoulder joint cavema side prosthesis is characterized in that: described prosthese profile is configured as the kidney type, and prosthese is provided with for the fixed screw hole of screw.
Described prosthese thickness of thin layer is less than 5mm.
Described a kind of shoulder joint cavema side prosthesis, its described screw are that tabernacle closes screw, and promptly its screw is a hollow design.
Described a kind of shoulder joint cavema side prosthesis, its described screw closes screw for two tabernacles, and so-called tabernacle closes screw, is meant that its screw is a hollow design.
Described a kind of shoulder joint cavema side prosthesis, its described screw hole are located at prosthetic surface each 1/3rd place up and down respectively.
Described a kind of shoulder joint cavema side prosthesis, its screw comprise the head of a nail and nail body two parts, and described head of a nail heart is interior hexagonal configuration design, and nail body heart designs for cylindrical hollow.
After adopting said structure, the design of prosthese thin layer＜5mm reduces losing of prosthese one lateral cartilages sending down the fishbone; Two tabernacles close the design concept and the method for screw technique for fixing, and promptly two tabernacles close screw designs, and it can preserve the bone amount, early stage good stability; At prosthetic surface each 1/3rd five equilibrium position pedicle screw up and down, it has well anti-revolving and stabilization function in addition; The head of a nail heart of screw is interior hexagonal configuration design, provides and twists the impetus that screw is used, and nail body heart designs for cylindrical hollow.
Description of drawings
Fig. 1 is a contour structures sketch map one of the present invention;
Fig. 2 is a contour structures sketch map two of the present invention;
Fig. 3 closes the sketch map of screw for tabernacle of the present invention.
The specific embodiment
In order to make those skilled in the art person understand the present invention program better, the present invention is described in further detail below in conjunction with drawings and embodiments.
Please refer to shown in Fig. 1 to 3, a kind of shoulder joint cavema side prosthesis, described prosthese 1 profile is configured as the kidney type, and prosthese 1 is provided with for screw 2 fixed screw holes 11; Described screw hole 11 is located at each 1/3rd place up and down, prosthese 1 surface respectively.
Described prosthese 1 thickness of thin layer A is less than 5mm.
With reference to shown in Figure 3, described screw 2 closes screw for two tabernacles, and so-called tabernacle closes screw 2, and promptly its screw 2 is a hollow design; Screw 2 is divided into the head of a nail 21 and nail body 22 two parts, and the head of a nail 21 hearts of screw 2 are interior hexagonal configuration design, and the impetus of twisting screw 2 usefulness is provided, and nail body 22 hearts of screw 2 design for cylindrical hollow, and the diameter of the head of a nail 21 will be less times greater than the overall diameter of nail body 22.
After adopting said structure, the design of prosthese 1 thin layer＜5mm reduces losing of prosthese one lateral cartilages sending down the fishbone; Two tabernacles close the design concept and the method for screw 2 technique for fixing, and promptly two tabernacles close screw designs, and it can preserve the bone amount, early stage good stability; At prosthetic surface each 1/3rd five equilibrium position pedicle screw up and down, it has well anti-revolving and stabilization function in addition; The head of a nail heart of screw is interior hexagonal configuration design, provides and twists the impetus that screw is used, and designs for cylindrical hollow in the nail body of screw.
Though described the present invention by embodiment, those of ordinary skills know, the present invention has many distortion and variation and do not break away from spirit of the present invention, wish that appended claim comprises these distortion and variation and do not break away from spirit of the present invention.
Claims (2)
