The advantages of reamer for hip arthroplasty,acetabulum holding locator of the present invention, is：
1) by positioning of the reamer for hip arthroplasty,acetabulum locator to reamer for hip arthroplasty,acetabulum, realize reamer for hip arthroplasty,acetabulum can above acetabular bone Cranial defect position
Accurate filing it is moulding, ensure that the postacetabular stability of Using prosthesis human body；
2) solve for above acetabular bone during Cranial defect, it is necessary to using acetabular bone cushion block prosthese case filing human body acetabular bone when
The problem of size is unstable is ground, the vacation of specific standard size can be used according to the different situations of the acetabular bone defect of patient
Body, the stable acetabular fossa being engaged with acetabular bone cushion block prosthese is moulded, so as to avoid due to acetabular bone cushion block prosthese and human body hip
The fit dimension of mortar nest it is inaccurate and caused by prosthese loosen too early, reduce the pain of patient；
3) adjusting support member by thickness can realize to enter according to grinding size of the acetabular bone defect situation of patient to acetabular bone
Row is freely adjusted, to adapt to the precise match of acetabular bone cushion block prosthesis size and acetabular fossa simultaneously；
4) it can make reamer for hip arthroplasty,acetabulum on request stably above filing Human Physiology acetabular fossa, ensure that acetabular bone cushion block prosthese can
Accurately and stably it is implanted into human body acetabular bone；
5) operating theater instruments broad view of the invention, easy to operate, operation is smooth, make that doctor is happy, smoothly completes hand
Art, operation risk is reduced, saved operating time.
Brief description of the drawings
