Abstract
The invention provides a hinge type shoulder joint prosthesis. The hinge type shoulder joint prosthesis comprises a humerus handle and a humeral head, wherein the humerus handle comprises a humerus handle far-end part and a humerus handle near-end part, the humerus handle far-end part is hinged to the humerus handle near-end part, and the humeral head is connected with the humerus handle near-end part. According to the hinge type shoulder joint prosthesis, the humerus handle is formed by enabling the humerus handle far-end part to be hinged to the humerus handle near-end part, angles of the humerus handle near-end part and the humerus handle far-end part can be adjusted freely, and angles of the humeral head and the humerus handle are adjusted, namely the collodiaphyseal angle is adjusted. The collodiaphyseal angle can be adjusted freely as required, the prosthesis is close to the anatomical structure of the human shoulder joint, postoperative effect is good, and the shoulder activity range is large.
Description
Technical field
The present invention relates to the bone surgery implant, in particular to the hinge type shoulder joint prosthesis used in a kind of shoulder joint replacement operation.
Background technology
Omarthritis, head of humerus necrosis, serious fracture of the humeral head are common shoulder joint orthopaedic diseases, and it is quite ripe with the technology for the treatment of right-hand man head necrosis, omarthritis, fracture of the humeral head that modern medicine is implemented the shoulder joint replacement operation.In the early-stage cases of shoulder joint displacement, because the collodiaphyseal angle between old-fashioned artificial head of humerus and humerus handle prosthese is nonadjustable, this makes the prosthese of displacement can better not realize dissecting performance, thereby affects the mobility of shoulder joint after Rehabilitation.
Medical circle has several method be used to addressing the above problem, if by iconography, carried out better Design, design more rational implant angle again humeral head replacement by selecting eccentric function etc. to realize implanting rear effect more similar to the human dissection form.But but still can not realize the angle free adjustment between head of humerus and humerus handle.
Summary of the invention
The present invention aims to provide a kind of hinge type shoulder joint prosthesis, can not free adjustment with the collodiaphyseal angle solved between artificial head of humerus of the prior art and humerus handle prosthese, and make the prosthese of displacement can better not realize dissecting the problem of performance.
To achieve these goals, the invention provides a kind of hinge 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 is hinged with humerus handle near-end spare; Head of humerus, be connected with humerus handle near-end spare.
Further, offer column pin hole on humerus handle near-end spare, offer hinge hole on humerus handle far-end spare, pin passes column pin hole and hinge hole is hinged by humerus handle far-end spare and humerus handle near-end spare.
Further, on humerus handle far-end spare, slot is set, the projection coordinated with slot is set on humerus handle near-end spare.
Further, also comprise that screw connects humerus handle near-end spare and humerus handle far-end spare, the relative position of fastening humerus handle near-end spare and humerus handle far-end spare.
Further, screw passes humerus handle near-end spare butt humerus handle far-end spare.
Further, the hole passed of column pin hole and screw is separately positioned on the opposite end of 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 humerus handle near-end spare, the taper hole coordinated with projection is set on head of humerus.
Further, on humerus handle far-end spare, offer the elongated slot with screw fit.
Further, between the axis extended line of the centre of sphere of head of humerus and humerus handle near-end spare, has offset distance.
Apply the hinge type shoulder joint prosthesis of technical scheme of the present invention, the humerus handle is formed by humerus handle far-end spare and humerus handle near-end spare chain connection, but humerus handle near-end spare and humerus handle far-end spare angle free adjustment, realize that the adjusting of head of humerus and humerus handle angle is the adjusting of collodiaphyseal angle.Collodiaphyseal angle is free adjustment as required, makes prosthese more near the anatomical structure of patient's shoulder joint, makes postoperative effect better, and the shoulder activity reaches larger scope.
