Abstract
The utility model relates to an ilium fixing piece with a self-locking counter sunk and a support platform applied to a half pelvis prosthesis, which belongs to the technical field of artificial half pelvis prostheses. The ilium fixing piece is characterized in that: a self-locking nail through hole is formed laterally in the upper end of the ilium fixing piece, and is fixedly connected with a residual ilium self-locking nail; an inner cone and a bayonet are arranged at the lower end of the ilium fixing piece, and are connected with an outer cone on a cotyle prosthesis and an anti-rotation neck in a matching way; and a platform which facing upwards and is used for supporting a residual ilium is arranged between the inner core and the bayonet. The ilium fixing piece has the beneficial effects that: the ilium fixing piece is fixedly connected with the residual ilium through the self-locking nail, so that the problem of easiness in loosening existing in an ordinary screw is solved; and a platform for supporting the residual ilium is arranged on the ilium fixing piece, so that the shear or tension force of the prosthesis and the residual ilium is transformed into pressure stress, and the prosthesis is prevented from becoming loose. The ilium fixing piece has high stability, does not become loose easily, and meets the requirement of structural and functional reconstruction of a half pelvis and a hip joint after half pelvic tumor resection in which a part of ilium is preserved in clinic.
Description
Technical field
This utility model belongs to the artificial semi-pelvis prosthesis technical field, relate to a kind of ilium fixture with self-locking nail hole and rest platform for semi-pelvis prosthesis, carry out structure and reconstruction that pelvic ring is rebuild, realized half pelvis and hip joint behind half pelvic tumor resection to the reservation of part ilium.
Background technology
Pelvic tumor is more common, accounts for the 3%-4% of former bone tumor.Because pelvic tumor usually involves acetabular bone, and scope is huge, when operation need to be excised tumor fully, usually with half pelvis amputation, but the patient had not only lost the homonymy lower limb after the half pelvis amputation, and the forfeiture lower limb function, was subject to mentally very large strike.During at present pelvic tumor treatment, be devoted to Limb conserved therapy, simple excision keeps limbs of patient with half pelvis of tumor, and the reconstruction of pelvic ring becomes the key of recovering patient's lower limb function.
Artificial semi-pelvis prosthesis is adopted in the at present reconstruction of pelvic ring more, when tumor invading arrives rumpbone and acetabular bone, behind a small amount of rumpbone of simultaneously amputation, whole ilium, acetabular bone, part pubis or the whole pubis, the artificial semi-pelvis prosthesis that now is used for the treatment of clinically existence and stability is not good enough, easily rotation, the problem such as loosening, the artificial semi-pelvis prosthesis that for this reason need a kind of good stability, is not easy to become flexible satisfies demand clinically.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of higher stability that has, the ilium fixture of the semi-pelvis prosthesis that is applicable to amputation part ilium, acetabular bone, part pubis or all uses behind the pubis also is applicable to the ilium fixture of the semi-pelvis prosthesis that pubis keeps.
For achieving the above object, the technical solution adopted in the utility model is: the ilium fixture with self-locking nail hole and rest platform that is used for semi-pelvis prosthesis, it is characterized in that: the upper lateral of described ilium fixture is equipped with the self-locking nail hole, is used for being fixedly connected with remaining ilium self-locking nail; The lower end is equipped with inner cone and bayonet socket, with outer cone on the acetabular component be connected draw-in groove coupling and be connected; Be equipped with supine platform for the described remaining ilium of rest therebetween.
Good effect of the present utility model is: be distributed with the self-locking nail hole on (1) ilium fixture, be fixedly connected with remaining ilium by self-locking nail, avoided plain screw to have easily loosening problem; (2) be equipped with a levelling bench that is used for the remaining ilium of rest on the ilium fixture, change shearing or the tensile stress of prosthese and remaining ilium into compressive stress, the becoming flexible of prevention prosthese.Therefore this utility model good stability, be difficult for loosening, satisfy rebuild behind half pelvic tumor resection to the reserve part ilium clinically, the demand of manufacturing artificial semi-pelvis prosthesis.
Description of drawings
Fig. 1 is the ilium anchor structure schematic diagram with self-locking nail hole and rest platform for semi-pelvis prosthesis;
Fig. 2 is this utility model user mode syndeton schematic diagram (rear position).
Among the figure, 1-ilium fixture; 2-self-locking nail hole; 3-platform; 4-anti-rotation draw-in groove; 5-pubis connector; 6-acetabular component; 7-remaining ilium; 8-offside pubis.
The specific embodiment
Fig. 1 is the ilium anchor structure schematic diagram with self-locking nail hole and rest platform for semi-pelvis prosthesis.As shown in Figure 1, be used for the ilium fixture with self-locking nail hole and rest platform of semi-pelvis prosthesis, it is characterized in that: the upper end of described ilium fixture is equipped with side direction self-locking nail hole 2, is used for being fixedly connected with remaining ilium 7 self-locking nails; The lower end is equipped with inner cone and bayonet socket, with outer cone on the acetabular component 6 be connected draw-in groove 4 coupling and be connected; Be equipped with supine platform 3 for the described remaining ilium 7 of rest therebetween.
Described side direction self-locking nail hole 2 quantity have a plurality of.
Described acetabular component 6 and pubis connector 5 are fixedly connected with by screw.
This utility model user mode syndeton (rear position) as shown in Figure 2, between ilium fixture 1 and the remaining ilium 7 by placing the self-locking nail by self-locking nail hole 2 to be connected and fixed, pubis connector 5 one ends are fixedly connected with described acetabular component 6 screws, and the other end is used for and being connected and fixed of offside pubis 8; One supine platform 3 for the described remaining ilium 7 of rest is arranged on the ilium fixture 1, be used for the remaining ilium 7 of rest; Slit between described ilium fixture 1 and the remaining ilium 7 can be used from body bone or pad and fill, and operation technique is convenient.
A kind of ilium fixture with self-locking nail hole 2 and rest platform 3 for semi-pelvis prosthesis of this utility model, the supportive structure combined effect by self-locking nail and levelling bench is fixedly connected with remaining ilium 7, makes the steady in a long-term good, easy to use of prosthese.
