Description
Technical field
The present invention relates to the field of medical instrument technology, in particular to a kind of adjustable sacral prosthesis component.
Background technique
Rumpbone is merged by 5 pieces of sacrals, is the important composition part of pelvic ring.Sacral Tumors account in bone tumour case
There is certain proportion, operation excision is the main means of current treatment Sacral Tumors.Rumpbone, which not only has, keeps pelvis ring structure to connect
It is continuous, the effect of internal organ is protected, and there are also the functions of support ridge column.Therefore, rumpbone defect is by the stability to pelvis and backbone
It impacts.After Sacral Tumors excision, in order to regain the integrality of pelvic ring, rumpbone need to be rebuild.
The sacral prosthesis for generalling use nail, stick and various structures in the prior art is rebuild.It is carried out using tradition nail stick
The stability of reconstruction is insufficient, and long term clinical results are bad, and the sacral prosthesis of various structures is mostly used to be rebuild at present.
The anatomical structure of rumpbone is complicated, and different patients have different sacral bone structures.Meanwhile different patient tumors ranges are not
Together, when Sacral Tumors are cut off, the range that different patients need to cut off is different.After tumor resection, it will form different shape size and incline
The osteotomy surface of rake angle, sacral prosthesis are fixed together and combining with the osteotomy surface with pelvis.Moreover, because tumour position
Setting and causing tumour is not that respectively osteotomy shape size and angle also can be variant at left and right sides of rumpbone two sides, rumpbone or ilium,
And the existing sacral prosthesis used is mostly the non-adjustable structure of integral type, when use cannot achieve with the osteotomy surface after tumor resection into
Row precisely matching, it has to which osteotomy range is increased according to existing prosthese specification.
In the prior art there are also some customized type prostheses, preoperative needs are customized formula according to the case where different patients and set
Meter, processing, production cost undoubtedly will increase.This waits time and the financial burden of operation by tumor patient is increased.
