A kind of technical research explanation of pelvic traction approximator is provided on the present invention：Since 2005, osteotomy has been not required
Pelvic traction be close in Pubic symphysis diastasis correction in carried out, our team carried out the pelvis of non-osteotomy from 2008
Studies and clinical application is closed up in traction, by continuously improving, with the further investigation of our R＆D team and with related bone
The development of basin traction approximator is carried out in a deep going way；As our R＆D team designs and develops a kind of pelvic traction approximator,
Without osteotomy, using articulatio sacroiliaca as the point of rotation, pelvic joint and tough tensile force of belt are gradually resisted, is led by certain time continuation
Draw, inwardly, close up to the midline, fixed or bone collection mode is closed pubic symphysis in cooperation；By the test of fixed preparation, due to
It is larger to apply strength, only selects 2 force approximator stability are poor (to choose both sides anterior superior spine and pass through the company with spring for force
Extension bar applies pressure to the midline to complete closing course), avulsion fracture of anterosuperior iliac spine may be caused.Since the above-mentioned first generation is produced
Product still have defect, and therefore, we then has developed second generation product and third generation product；
The present invention provides a kind of pelvic traction approximator (belonging to third generation product), which reduces operation risk, reduces
Hospital stays, cost, comparatively safe, wound is small, effect affirmative.The present invention provides a kind of pelvic traction approximator (i.e. third generation
Pelvic traction approximator), the technical advantage in terms of mainly having as follows；1st, position and the fixed form in 4 forces have been continued；
The 2nd, the point of application is changed to connect respectively to the adjuster in 4 forces；3rd, rotary presser nut pressurizes, and has scale, rotation one on nut
It encloses as 1mm.
Pelvic traction approximator provided in an embodiment of the present invention realizes the purpose of correction Pubic symphysis diastasis, 1 its drop
Low abdomen wall tension, promotes healing；2nd, which raises urine control rates；3rd, pelvis normal development is promoted；4th, hip joint is maintained to stablize
Property；5th, penis shape is recovered.The present invention also provides a kind of pelvic traction approximator, force selection is reasonable；Each linkage is steady
It is fixed reliable；Pressue device can achieve the desired results.
Pelvic traction approximator provided in an embodiment of the present invention has the technical advantage of following aspect：
