Technical field
The present invention relates to a kind of bone grafting therapy fields, in particular to a kind of pubis prosthesis assembly.
Background technique
Pelvis is made of rumpbone, ischium, pubis, ilium, and pelvic tumor accounts for about the 3%-4% of primary bone tumour.Wherein
Cartilage system tumor is the most common, is secondly giant cell tumor of bone, osteogenic sarcoma etc., children's Ewing sarcoma is also apt to occur in pelvis.Bone
The normal latency development of basin malignant tumour, it is clear sometimes for for a long time to diagnosis from occurring symptom for the first time.Due to pelvic position
Relatively deep, tumour early stage is difficult to find, when there are clinical symptoms, gross tumor volume is larger, thus excision of performing the operation is extremely difficult.Shame
Bone tumour is relatively fewer, but still can not be ignored to the threat to people living.
Currently, the method for the treatment pubis tumour generallyd use has:
(1) tumour curettage and bone grafting operation are suitable for benign bone tumour；
(2) resection and bone grafting operation are suitable for benign and low potential malignancy bone tumour；
(3) amputation suitable for huge malignant bone tumor or has soft tissue person near extensive involve, but also needs cautiously to examine
Consider.
The reconstruction of pubis prosthese needs to reach stability fixation and left and right sides pubis with respect to fine motion.For bone grafting operation, sclerotin
Source is to need key problems-solving.Even if solving sclerotin source, but when tumour crosses pubic symphysis, bone grafting is difficult to solve
The needs of fine motion in pubic symphysis.

The inner wall clearance fit of connecting hole.
Further, connecting hole is multiple, and fastener is selectively threaded through in one of connecting hole.
Further, multiple connecting holes are arranged along the extending direction interval of connector.
Further, fastener is fastening screw, and connecting hole is the threaded hole with fastening screw clearance fit.
Further, connector includes first connecting portion and second connecting portion interconnected, first connecting portion and second
Step structure is formed between interconnecting piece, is provided with the stepped hole matched with step structure on a pubis prosthese.
Further, two pubis prostheses are respectively the first pubis prosthese and the second pubis prosthese, and stepped hole setting is the
On one pubis prosthese, fastener is threaded through on the second pubis prosthese.
Further, along the extending direction perpendicular to connector, the section of connector is polygon.
Further, connector is medical low-elastic modulus material.
Further, the material of connector is ultra-high molecular weight polyethylene.
Further, multiple soft tissue fixation holes are offered on pubis prosthese.
It applies the technical scheme of the present invention, pubis prosthesis assembly includes two pubis prostheses, and two pubis prostheses are solid respectively
Be scheduled on left and right pelvis, be connected as one two pubis prostheses by connector, and fixed by fastener, fastener with
Pubis prosthese clearance fit, in user's walking, fastener and pubis prosthese have the amount of fine motion, and then solve pubis prosthese
The problem of fine motion is needed between connector.
