Background technique
Pelvis is the important link for connecting backbone and main weight loading exercise structure, the power of movements generation such as sits, walks along it
Bony structure is conducted to backbone.The only way which must be passed that pelvic ring is also important blood vessel, nerve and reproduction and digestive system passes through, because
The serious damage of this pelvic ring does not only result in very high lethality and disability rate, and malunion, chronic occurs for malpractice
The probability of the complication such as pain is also very high.Early stage resets and fixation can improve prognosis.
In addition, femoral neck cannulated screw Internal fixation technology is because operation wound is small, intraoperative blood loss for posterior ring pelvic fracture
Less, the advantages that infection risk is low and interior fixed is received by more and more doctors, however in the merging of femoral neck cannulated screw
In the process but there is problems, for example screw merging region is narrow, sets nail fault, Unstable internal fixation；Under traditional X-ray examination
Can not real-time tracing guide pin, cannot clearly show that sacrum hole site, therefore, set nail during nerve, the risk of injury of blood vessel it is larger,
And it needs constantly to have an X-rayed in art, patient and medical staff is made to receive relatively large x-ray radiation amount.Computerized navigation set can be improved
It sets nail accuracy and reduces perspective, but is expensive, the universal difficulty of basic hospital.
Summary of the invention
