Description
Technical field
The present invention relates to bone surgery implanting prosthetic field, in particular to a kind of combination type shoulder joint prosthesis.
Background technology
Omarthritis, head of humerus necrosis, serious fracture of the humeral head all are common shoulder joint orthopaedic diseases.In the modern medicine, the technology of implementing shoulder joint replacement operation treatment right-hand man head necrosis, omarthritis, fracture of the humeral head is quite ripe.In the early-stage cases of shoulder joint replacement operation, do not have the adjustable design in mutual alignment (for example collodiaphyseal angle, back rake angle and offset distance) to make the prosthese of displacement can better not realize dissecting performance between old-fashioned head of humerus and the humerus handle prosthese, thereby influence the mobility of shoulder joint after patient's rehabilitation.If can realize that the mutual alignment between head of humerus and the humerus handle is adjustable, can make prosthese can be more near the anatomical structure of human body, thereby further improve postoperative effect.Current medical circle has some kinds of methods to be used for the treatment of similar purpose, as being undertaken designing before the better art by iconography, designs more rational implant angle, selects humeral head replacement of eccentric function etc. for use.These technology can realize between humerus handle and the head of humerus adjusting to a certain degree, and still, the position adjustable in these technology is still less, and the specification collocation is few, cause that the mobility of shoulder joint is adversely affected after patient's rehabilitation.
Summary of the invention
The present invention aims to provide a kind of combination type shoulder joint prosthesis, and is less to solve the collocation of shoulder joint prosthesis position adjustable of the prior art and specification, influences the problem of the mobility of shoulder joint after patient's rehabilitation.
To achieve these goals, the invention provides a kind of combination type shoulder joint prosthesis, comprising: the humerus handle, comprise humerus handle far-end spare and humerus handle near-end spare, humerus handle far-end spare removably is connected with humerus handle near-end spare; Head of humerus is connected with humerus handle near-end spare.
Further, humerus handle far-end spare is connected by slot with humerus handle near-end spare.
Further, on the humerus handle far-end spare slot is set, at humerus handle near-end spare projection is set.
Further, comprise also that holding screw passes humerus handle far-end spare butt humerus handle near-end spare.
Further, head of humerus is connected by taper hole with humerus handle near-end spare.
Further, the projection of taper type is set on the humerus handle near-end spare, the taper hole that cooperates with projection is set on the head of humerus.
Further, has offset distance between the axis extended line of the centre of sphere of head of humerus and taper hole.
Further, has offset distance between the axis extended line of the centre of sphere of head of humerus and humerus handle near-end spare.
Further, the combination type shoulder joint prosthesis adopts medical metal to make.
Use technical scheme of the present invention, the humerus handle of combination type shoulder joint prosthesis is formed by connecting by slot by humerus handle far-end spare and humerus handle near-end spare, humerus handle near-end and the mutual assembly of humerus handle far-end that can multiple different size in the art be with the multiple variation combination of collodiaphyseal angle, back rake angle and the offset distance of realizing the combination shoulder joint prosthesis.It is more similar to the human dissection form to realize that shoulder joint prosthesis is implanted the back effect, is conducive to postoperative rehabilitation.
Description of drawings
The Figure of description that constitutes the application's a part is used to provide further understanding of the present invention, and illustrative examples of the present invention and explanation thereof are used for explaining the present invention, do not constitute improper restriction of the present invention.In the accompanying drawings:
Fig. 1 shows the combination sketch map of combination type shoulder joint prosthesis of the present invention; And
Fig. 2 shows the decomposing schematic representation of combination type shoulder joint prosthesis of the present invention.
The specific embodiment
Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Referring to Figure 1 and Figure 2, combination type shoulder joint prosthesis of the present invention comprises humerus handle 1 and head of humerus 2, humerus handle 1 is formed by connecting by the projection slot by humerus handle far-end spare 3 and humerus handle near-end spare 4, joins locking by awl between head of humerus 2 and the humerus handle near-end spare 4.
Referring to shown in Figure 2, the upper end cone match of the inner conical surface of head of humerus 2 and humerus handle 1 keeps certain taper can realize head of humerus 2 and 1 locking of humerus handle.The taper type projection with certain taper is stretched out in humerus handle near-end spare 4 upper ends, joins locking with the internal taper hole awl on the head of humerus 2.The centre of sphere of head of humerus 2 on the axis extended line of head of humerus 2 taper holes, does not have certain offset distance, makes head of humerus 2 head of humerus 2 when taper hole rotates have multiple relative position with humerus handle 1.Humerus handle far-end spare 3 and humerus handle near-end spare 4 cooperate by the projection slot, for example at humerus handle far-end spare 3 groove are set, and at humerus handle near-end spare 4 projection are set.Preferably, for firm cooperation, can " soil " font or the projection of " worker " font be set at humerus handle near-end spare 4, and the groove of respective shapes is set at humerus handle far-end spare 3.Holding screw 5 passes humerus handle far-end spare 3 butt humerus handle near-end spares 4, tightens lockable humerus handle far-end spare 3 and humerus handle near-end spare 4, prevents the two relative slip.Design has certain included angle on the upper surface of humerus handle near-end spare 4 and the lower surface sphere, corresponding to sagittal plane and coronalplane.The humerus handle near-end spare 4 and 3 assembly of humerus handle far-end spare of multiple different size can be arranged, and can realize making up shoulder joint prosthesis like this has multiple collodiaphyseal angle or back rake angle and offset distance.
