Description
Technical field
This utility model relates to a kind of artificial prosthesis, is specifically related in a kind of pelvic tumor resection reconstruction operations the ilium defect reconstruction prosthese used.
Background technology
Pelvis is the position that bone tumor is sent out well, and pelvic tumor can be divided into primary tumo(u)r and metastatic tumour.The former is mainly chondrosarcoma, osteosarcoma and Ewing sarcoma, and the latter is common in the Bone tumour of mastocarcinoma, renal carcinoma, carcinoma of prostate, pulmonary carcinoma etc..Pelvic tumor incidence of occult and early diagnosis is difficult, scope of invading when often finding is the biggest, adds that pelvis surrounding anatomic is complicated and adjoins with a lot of important organs, and operating difficulty is big, and complication is many, and curative effect is not good enough, and mortality rate is high.At present, pelvic tumor is mainly taked half pelvis excision or improvement half pelvis excision amputation, but the excision of any pelvic tumor all can cause Cranial defect, Cranial defect can cause patient's trunk and lower limb seriality to be interrupted, and impact is stood and walking with load, patient can not undertake body weight, and after producing pain, and patient's long-time walking with load when of walking, acetabular bone there will be introversion, upper shifting, scoliosis can be caused after pelvic inclination, cause patient's postoperative life quality degradation.
Pelvis is divided into following four region by functional area: I district (ilium), this region is mainly the attachment point of gluteus and iliacus, is the attachment point controlling hip joint major muscles, will have a strong impact on the function of hip after excision；II district (Periacetabular), this region is joint portion, being femoral head and the main positions of acetabular bone composition hip joint, even if retaining good power set (muscle) after excision, also will have a strong impact on hip joint mobility；III district (pubis, ischium), this region is the main portions of Pelvic floor attachment, mainly inguinal ligament and the Pelvic floor attachment point of maintenance perineum tension force；IV district (around sacroiliac joint), this region mainly realizes the stress conduction from trunk to pelvis, is amphiarthrosis.
In order to regain the integrity of basin bone, occur in that various pelvic tumor resection reconstruction operations at present, mainly application pedicle nail bar system carries out waist sacrum-pelvic structures reconstruction, or using nail-stick system to combine biology reconstruction, the latter includes that Fibula autograft is transplanted and titanium net+autologous bone/allograph bone is rebuild.The reconstruction of Cranial defect can enable the patient to sit, stand and walk, to maintain the required activity of daily life.But current reconstruction operations is difficulty with biological fixation, simple nail-stick system is rebuild at a specified future date due to metal fatigue, it may appear that loosening and fracture of peg rod, and Structural bone graft is difficulty with bone graft and the fusion of defect pelvis owing to lacking stable environment in early days.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide in a kind of pelvic tumor resection reconstruction operations the ilium defect reconstruction prosthese used.

In a preferred embodiment, described osteocyte is opened and is made by electron beam dissolution method or stereolithography into portion, its thickness is 1cm, pore diameter is 300-500 μm, porosity is 80-90%, this porosity can provide optimal bony union interface, is best suitable for osteocyte and creeps, and is capable of revascularization.
In a preferred embodiment, described osteocyte is opened and is made by electron beam dissolution method or stereolithography into portion, and its pore diameter is 1-2mm, porosity 60-65%.
In a preferred embodiment, on peripheral reinforcement described in two, interval has several holes, in order to carry out the soft tissue attachments such as tendon in Rhizoma Atractylodis Macrocephalae.
In a preferred embodiment, the fixing hole in described defect main body is three screw holes, and is individually fixed in rumpbone, pubis and ischium direction by three pieces of fixing screws.
In a preferred embodiment, described soft tissue facies posterior hepatis is internally provided with metallic strengthening structure, to improve the mechanical performance of defect main body.
In a preferred embodiment, also include an optional load connection device, described optional load tipping is set to the screw connection structure being fixed in described defect main body, described screw connection structure has a short-tail protruding from described defect main body and emits, described short-tail emits and has one for putting into the through hole of metal bar, and fixed by nut, thus realize the connection with pedicle screw fixation system.
This utility model is owing to taking above technical scheme, it has the advantage that this utility model can be widely applied for the defect and restore in pelvis seriality stage casing after ilium tumor resection, no matter return to patient's function at a specified future date and quality of life from recent structure, can be significantly improved.
