Abstract
The invention discloses a kind of acetabular component, for replacing bone tumour in acetabular bone, including the liner (4) being set in outside femoral head bulb, the outer cover of liner (4) is provided with acetabular cup (3), liner (4) can be rotated between femoral stem bulb and acetabular cup (3), prevent acetabular component from dislocating with the openings of sizes for adjusting acetabular cup (3).A kind of acetabular component of the present invention, acetabular component can be blended with the acetabular bone in patient's body, and acetabular component is fixed more firm；The activity point of view scope of acetabular bone is larger, it is therefore prevented that acetabular component is dislocated；Acetabular component can arbitrarily be assembled according to the situation of different patients, meet the acetabular component demand of different patients；Limb can be protected for patient, meet the position of different osteotomy in hip joint acetabular surgery art, acetabular component is consistent with the acetabular bone position in original patient's body and the angle human body line of force, and internal function can effectively and reliably be rebuild.
Description
Technical field
The present invention relates to a kind of medical prosthesis, more particularly to a kind of acetabular component for substituting bone tumour in pelvis acetabular bone.
Background technology
Because lesion can cause pelvis malignant bone tumor on the pelvis of human body, bone tumour should be cut off, should during excision
Thorough tumor resection is reached, the generation of complication is reduced as far as possible and rebuilds reliable and effective function.
Because pelvic tumor resection reconstruction operations are complicated, therefore the image data of patient should be carefully analyzed in the preoperative, clearly
With the scope of Gu Wai soft mass in the bone of tumour, many prostheses can not reach the standard of above-mentioned requirements at this stage.
The content of the invention
It is an object of the invention to provide a kind of replacement bone tumour, prevent the acetabular component of dislocation.
To achieve the above object, a kind of concrete technical scheme of acetabular component of the invention is：
A kind of acetabular component, for replacing bone tumour in acetabular bone, including is set in the liner outside femoral head bulb, liner
Outer cover be provided with acetabular cup, liner can be rotated between femoral stem bulb and acetabular cup, to adjust the openings of sizes of acetabular cup
Prevent acetabular component from dislocating.
Further, the both sides outside acetabular cup are connected to the support wing and fixture, and acetabular cup is by asking wing fixture to insert
Enter in acetabular bone to fix acetabular component.
Further, it is provided with the support wing in conehead, the outside wall surface of acetabular cup and sets fluted, conehead can turns in groove
Dynamic, acetabular cup can rotate to adjust the installation site of acetabular component relative to the support wing.
Further, chain joint is provided with the outside wall surface of acetabular cup, acetabular cup is connected by chain joint with fixture, linked
Head can be rotated in fixture, and acetabular cup can rotate to adjust the installation site of acetabular component relative to fixture.
Further, the support wing is bone trabecula, and acetabular bone can be grown into bone trabecula, so that acetabular component is merged one with acetabular bone
Rise.
A kind of advantage of acetabular component of the present invention is：
1) acetabular component can be blended with the acetabular bone in patient's body, and acetabular component is fixed more firm；
2) the activity point of view scope of acetabular bone is larger, it is therefore prevented that acetabular component is dislocated；
3) acetabular component can arbitrarily be assembled according to the situation of different patients, meets the acetabular component demand of different patients；
4) limb can be protected for patient, meets the position of different osteotomy in hip joint acetabular surgery art, acetabular component and original trouble
Acetabular bone position and the angle human body line of force in person's body is consistent, and internal function can effectively and reliably be rebuild.
Brief description of the drawings
Fig. 1 is the structural representation of the acetabular component of the present invention；
Fig. 2 is the side view of the acetabular component of the present invention.
Embodiment
In order to be better understood by the purpose of the present invention, structure and function, below in conjunction with the accompanying drawings, to a kind of acetabular bone of the present invention
Prosthese does further detailed description.
As depicted in figs. 1 and 2, its a kind of acetabular component for being shown as the present invention, for being implanted into acetabular bone and replacing bone tumour
Part, including the liner 4 outside femoral head bulb (not shown) is set in, the outer cover of liner 4 is provided with acetabular cup 3, liner 4
It can be rotated between femoral stem bulb and acetabular cup 3, prevent acetabular component from dislocating with the openings of sizes for adjusting acetabular cup 3, acetabular bone
Prosthese activity point of view scope is larger.Wherein, the internal face of the outside wall surface of liner 4 and acetabular cup 3 is shiny surface, reduces and rubs
Wipe, add the service life in joint.
Further, the support wing 1 is bone trabecula, and acetabular bone can be grown into bone trabecula, so that acetabular component is merged one with acetabular bone
Rise, fixation is more firm.
Further, one end outside acetabular cup 3 is connected with the biomimetic type support wing 1, is inserted by the biomimetic type support wing 1 in acetabular bone
Dove-tail form groove 31 is provided with to fix to be provided with dovetail aerofoil profile conehead 2, acetabular cup 1 in acetabular component, the support wing 1, conehead 2 can
In embedded groove 31, the support wing 1 is connected by conehead 2 with acetabular cup.In addition, conehead 2 can be rotated in groove 31, the phase of acetabular cup 3
Rotated for the support wing 1, to adjust the installation site of acetabular component, in the case of different osteotomy, by adjusting acetabular component
Position with ensure acetabular bone the line of force and human body it is consistent.
Further, the other end outside acetabular cup 3 is connected with pubis Medullary fixation part 6, and acetabular bone is inserted by fixture 6
Interior that bulb type pubis chain joint 5 is provided with acetabular component, the outer wall of acetabular cup 3 to fix, chain joint 5 is set in fixture 6
It is interior, and can be rotated in fixture 6, acetabular cup 3 can be rotated relative to fixture, to adjust the setting angle of acetabular component,
In the case of different osteotomy, by adjusting the position of acetabular component with ensure acetabular bone the line of force and human body it is consistent.Wherein, can root
According to the demand outfit different length of patient, the pubis Medullary fixation part 6 of specification.
A kind of acetabular component of the present invention, can be blended with the acetabular bone in patient's body, and acetabular component is fixed more firm；Hip
The activity point of view scope of mortar is larger, it is therefore prevented that acetabular component is dislocated；Acetabular component can arbitrarily be assembled according to the situation of different patients,
Meet the acetabular component demand of different patients；Limb can be protected for patient, meet the position of different osteotomy in hip joint acetabular surgery art
Put, acetabular component is consistent with the acetabular bone position in original patient's body and the angle human body line of force, internal function can be effectively and reliable
Reconstruction.
The present invention is further described by specific embodiment above, it should be understood that, here specifically
Description, should not be construed as the restriction to the spirit and scope of the invention, and one of ordinary skilled in the art is reading this explanation
The various modifications made after book to above-described embodiment, belong to the scope that the present invention is protected.
