It sets.
Background technique
Fracture is a kind of common disease, and the continuity of bone structure is broken completely or partially.It is more common in children and the elderly,
Young people also happens occasionally.For example the portion can be caused to fracture when violence directly acts on a certain position of bone, make injury
It fractures, and often with different degrees of soft tissue injury.Wherein, for multiple fracture, pelvic fracture, femoral fracture, ridge
Spinous process of the seventh cervical vertebra folding and serious open fracture, the extensive soft tissue injury of patient Chang Yin bleed profusely, have an intense pain or concurrent internal organ
Damage etc. and cause to suffer a shock.For example pelvic fracture accounts for about the 3%~8% of whole body fracture, is a kind of usually caused by high-energy injury
Serious wound, disability rate are up to 50%~60%, and lethality is up to 13% or more.Traditional pelvis-repositioning method, by
X-ray is repeatedly shot in art, is determined and is resetted path.The method is positioned by doctor's hand operation and by range estimation.Doctor and trouble
The amount of radiation that person receives is big, and doctor by two dimensional image can not accurate perception fracture condition information, path planning exists certain
Difficulty is easy to leave the deformity of pelvis to influence reduction of the fracture quality, leg length discrepancy, the complication such as low back pain, when serious very
It is corrected to needing to carry out second operation.In addition, in traditional pelvis-repositioning operation, doctor need manually or using reduction instrument into
Pelvis axial direction and rotation displacement are corrected in the movements such as row sled group, drawing, extruding, and requirement continues firmly but cannot exert oneself during this
It is too quickly to prevent new fracture, this often consumes the huge physical strength of doctor, and since the physical endurance of people leads to tradition
The problems such as repositioning method is insufficient with reseting precision there are stability shortcoming.
Although current lot of domestic and foreign scientific research institution, engineers and technicians and medical worker carry out reduction of the fracture mechanism
Study and obtain certain achievement, as U.S. Starr et al. develop pelvic fracture reset frame, Chinese PLA General Hospital development
The series-parallel pelvis of a kind of six degree of freedom that Unstable pelvic fractures reset frame and BJ University of Aeronautics & Astronautics Zhao Lu et al. are announced
Reduction of the fracture machine people etc., but these are studied or can only complete pelvic fracture reattachment surgery by the hand-held auxiliary of doctor, or
Operating flexibility and larger reset force cannot be had both, clinical demand is unable to satisfy.It may be concluded that existing pelvic fracture is multiple
Position system respectively has disadvantage, cannot adapt to operating room environment very well, really solves clinical problems faced.
