Abstract
The invention belongs to the technical field of artificial half-pelvic prosthesis and particularly relates to a half-pelvic prosthesis for patients with all ilium and acetabulum cut off, which is characterized in that the upper end of an ilium fixture has a press rod insertion hole; the lower end of the press rod is placed in the press rod insertion hole; and the upper end of the press rod is fixedly connected with one end of the pedicle screw. One side face of the ilium fixture has a U-shaped connecting block, the inner side of the bottom of the connecting block is provided with a press rod fixing hole which is round; the lower end of a second press rod is placed in the press rod fixing hole; and a screw running through the connecting rod and the ilium fixture to fixedly connect the connecting rod and the ilium fixture and tightly connect the connecting rod with the press rod. The device has the advantages that one end of the pedicle screw is fixed in the lumbar vertebra or left sacrum of a patient, the other end of the pedicle screw is fixedly connected with the press rods on the ilium fixture, and thus, the ilium fixture is fixed, and the prosthesis is stabilized.
Description
Technical field
The invention belongs to the artificial semi-pelvis prosthesis technical field, be specifically related to a kind of semi-pelvis prosthesis that is applicable to that the whole iliums of amputation, acetabular bone, part pubis or whole pubis patient use.
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, usually need carry out half pelvis amputation art.Though operation is excised tumor fully, the patient has lost the homonymy lower limb, has not only lost the lower limb body function, and receives very big strike mentally.In the time of pelvic tumor treatment at present, generally attempt to protect the limb Comprehensive Treatment, excision has half pelvis of tumor, and the reconstruction of pelvic ring becomes the key of recovering lower limb function.
Artificial semi-pelvis prosthesis is adopted in the reconstruction of pelvic ring at present more; When tumor invading arrives ilium and acetabular bone; Need the whole iliums of amputation simultaneously, acetabular bone, part pubis or whole pubis; Even also needing a small amount of rumpbone of amputation, the artificial semi-pelvis prosthesis that at present is used to treat exists stability not good enough clinically, easily rotation, problem such as loosening.
Summary of the invention
The technical problem that the present invention will solve provides a kind of higher stability that has, and is applicable to the whole iliums of amputation, acetabular bone, part pubis or the whole pubis of amputation, even the semi-pelvis prosthesis that uses behind a small amount of rumpbone of amputation.
For achieving the above object; The technical scheme that the present invention adopts is: a kind of semi-pelvis prosthesis that is applicable to that the whole iliums of amputation, acetabular bone patient use; Comprise ilium fixture, acetabular component and pubis connector, the anti-rotation bayonet socket by the band tapering between said ilium fixture and the said acetabular component connects, and said acetabular component is fixedly connected with said pubis connector screw; It is characterized in that: the upper end of said ilium fixture is equipped with the pressure bar patchhole; The lower end of pressure bar places in the said pressure bar patchhole, and inserts the hole wall radial screw by said pressure bar and fix, and the upper end of said pressure bar is fixedly connected with the end of pedicle nail one end.
One side of said ilium fixture is equipped with the U-shaped contiguous block; The both sides doubling of U-shaped is overlapping; The centre is equipped with the slit, and the bottom inside of said U-shaped contiguous block is equipped with the pressure bar fixing hole, and is rounded; The lower end of second pressure bar places said pressure bar fixing hole; Through running through the screw of contiguous block and ilium fixture, that realizes said contiguous block and said ilium fixture is fixedly connected and realizes being fastenedly connected of said second pressure bar, and the upper end of said second pressure bar is fixedly connected with the end of second pedicle nail, one end.
Said pedicle nail and the pairing of said pressure bar are used, and quantity is 1～2.
Good effect of the present invention is; An end and patient's lumbar vertebra or remaining rumpbone internal fixation through pedicle nail; The other end of pedicle nail is fixedly connected with pressure bar on the ilium fixture, has solved the fixing difficult difficult problem of ilium fixture, has increased prosthesis stability.
