Description
Technical field
The present invention relates to operating theater instruments, more particularly to a kind of pelvis lockplate system.
Background technology
Pelvic fracture is a kind of serious wound, more caused by high energy wound, account for fracture sum 1%~3%, half with
On be up to 50%~60% with complication or multiple injury, disability rate.Most serious is that hemorrhagic traumatic shock and pelvic cavity are dirty
Device associated injury, treatment is improper the very high death rate, up to 10.2%.According to statistics, in pelvic fracture 50%~60% by automobile
Traffic accident is caused, and 10%~20% is due to that pedestrian is hit, and 10%~20% is motorcycle wound, and 8%~10% is high falling
Wound, 3%~6% is that severe crush is hindered.Pelvic fracture caused by low energy wound is generally stable fracture, multiple to be born in the elderly
Fall and low speed traffic accident, or minor and sportsman's anterior superior spine or avulsion fracture of ischial tuberosity, the former is because of sartorius, the latter
Caused by Yin hamstrings shrink with sudden force, and the fracture caused by high energy external force is generally unstable fracture.
Pelvic fracture is more serious and complicated fracture, takes place mostly in high-energy damage, its curative effect and prognosis and reset
Fixed mass is closely related.Anatomical reduction as far as possible is required during operation, early functional exercise can reduce the hair of long term complication
It is raw.But for complicated pelvic fracture, the interior fixation more particularly, to hip fracture is relatively difficult.Fixing screws are placed as being stranded
Difficulty, is easily strayed into articular cavity or pelvic cavity, even if reaching anatomical reduction, and long term, which is also possible to reset, loses.Therefore, design meets part
Dissection is again particularly important beneficial to the internal fixation system operated in doctor's art.
