Abstract
The utility model discloses a kind of shoulder joint prosthesis of band suture net, including joint handle and ball and socket joint, the ball and socket joint are connect by joint handle end rotation axis outstanding with the joint handle；One layer of tendon suture net is wrapped up on the outside of the joint handle, the tendon suture net is shape and the consistent string bag structure of joint shank shape, stitch points of the mesh of the tendon suture net as tendon around shoulder joint.Using the tendon suture hole in tendon suture net replacement prosthesis in the utility model, avoid the limitation of suture hole number and position, in operation can flexible choice tendon suture position, utmostly restore tendon position, be conducive to restore musculature function；And since tendon suture is no longer by the limitation of suture hole number and position, it might even be possible to carry out many places suture to larger tendon, sewing effect is more stable, postoperative rehabilitation effect is good, shoulder mobility ability restores original function substantially, and activity freely, improves minimal invasive treatment, ability to work.
Description
Technical field
The utility model belongs to field of medical device, and prosthese is used in specifically a kind for the treatment of.
Background technique
Currently, be clinically widely used displacement artificial shoulder joint prosthesis mode, come treat shoulder joint Osteoarthritis,
The diseases such as humerus head ischemic necrosis.
There are tendon of subscapularis muscle, tendon of supraspinatus muscle, tendon of infraspinatus muscle, roundlet tendon, pectoralis major, deltoid muscle, back wealthy around shoulder joint
The tendon tissues such as flesh.Each tendon is attached to humerus different location, coordinates to complete bend, stretch, outreach, interior receipts, outward turning, inward turning, ring
Turn etc. shoulder joint movement.Displacement artificial shoulder joint prosthesis needs to restore the body function of the tissues such as above-mentioned tendon, could maximum journey
Degree restores the function of shoulder joint, realizes the Anatomical Reconstruction of shoulder joint.
Its tendon suture hole number of existing proximal humerus shoulder joint prosthesis is less, and is distributed in the humerus of nearly joint position more
On bulb, human anatomic structure feature is not met.Originally it is attached to the humerus head slightly tendon of position down, as deltoid muscle, chest are big
Flesh, latissimus dorsi, musculus teres major etc. can only select to be sewn to nearly humerus bulb sewing hole nearby.Postoperative, multiple tendon seams are caused in this way
It closes a position, is overlapped at tendon suture position or positional shift, tendon function cannot be rebuild as former state, patient's shoulder mobility
Range and mobility are limited, and joint function restoration effect is poor, and the postoperative shoulder mobility range of patient is limited, life, work
Ability decline.
Summary of the invention
Goal of the invention: the utility model aim is in view of the deficiencies of the prior art, to provide a kind of convenient for suture tendon
Shoulder joint prosthesis helps patient to restore musculature function.
Technical solution: the shoulder joint prosthesis of band suture net described in the utility model, including joint handle and ball and socket joint, the pass
Section header is connect by joint handle end rotation axis outstanding with the joint handle；One layer of tendon suture is wrapped up on the outside of the joint handle
Net, the tendon suture net are shape and the consistent string bag structure of joint shank shape, and the mesh of the tendon suture net is made
For the stitch points of tendon around shoulder joint.
Further preferably technical solution is the utility model, and the joint handle is made of button and intramedullary needle two parts,
Intramedullary needle penetrates the head of the button, fixes with the button.
Preferably, the connecting portion of the button and the intramedullary needle is provided with step surface, for fixing the tendon seam
Close net.
Preferably, the button and intramedullary needle are integrated.
Preferably, the tendon suture net is made of medical polyester material.
Preferably, the mesh size of the tendon suture net is 2-10 mm.
Preferably, the outer surface of the joint handle is frosting.
The utility model has the advantages that avoiding seam using the tendon suture hole in tendon suture net replacement prosthesis in (1) the utility model
The limitation for closing hole number and position, in operation can flexible choice tendon suture position, utmostly restore tendon position, favorably
In recovery musculature function；And due to tendon suture no longer by suture hole number and position limitation, it might even be possible to compared with
Big tendon carries out many places suture, and sewing effect is more stable, and postoperative rehabilitation effect is good, and shoulder mobility ability restores original substantially
Function, activity freely, improve minimal invasive treatment, ability to work；
(2) setting sewing hole is not needed in the utility model on joint handle, manufacturing process is simpler, advantageously reduces life
Produce cost；
(3) reticular structure of the tendon suture net of the utility model and joint handle outer surface are all designed as frosting
It may advantageously facilitate surrounding soft tissue's attachment, have positive influence to postoperative rehabilitation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the shoulder joint prosthesis of band described in the utility model suture net；
In figure, 1- joint handle, 2- ball and socket joint, 3- rotation axis, 4- tendon suture net.
Specific embodiment
Technical solutions of the utility model are described in detail below by attached drawing, but the protection scope of the utility model
It is not limited to the embodiment.
Embodiment: a kind of shoulder joint prosthesis of band suture net, including joint handle 1 and ball and socket joint 2, ball and socket joint 2 pass through joint
Handle end rotation axis 3 outstanding is connect with joint handle 1.Joint handle 1 is made of button and intramedullary needle two parts, the outer surface of button
For frosting, intramedullary needle penetrates the head of button, fixes with button, and button and intramedullary needle are integrated, in button and marrow
The connecting portion of needle is provided with step surface.
On the outside of joint handle 1 wrap up one layer of medical polyester material made of tendon suture net 4, tendon suture net 4 be shape with
The consistent string bag structure of 1 shape of joint handle, the head of tendon suture net 4 are fixed on the step surface of button.Tendon suture net 4
Mesh size is 2-10 mm, stitch points of the mesh as tendon around shoulder joint.
As described above, although the utility model has been indicated and described referring to specific preferred embodiment, it must not
It is construed to the limitation to the utility model itself.In the spirit and scope for not departing from the utility model that appended claims define
Under the premise of, it can various changes can be made in the form and details to it.
