Modified backbone operation support headstock

The utility model provides a backbone operation support, its characterized in that: that modified backbone operation support headstock goes up and down as follows mainly and removes with controlling lie in the annular transparent air bag of uncovered ellipse on the headstock, through the fixed aerator A that is equipped with in the headstock ring with said air bag becomes integrative, with the screw rod that has the inlet port in the air bag becomes integrative its, fixes the air bag on the ring that corresponds the headstock with the nut, what said inlet port was equipped with on through the air inlet housing lateral wall takes the thin rubber tube of thin rubber tube hoop to link to each other, fills in for the shutoff in the air inlet housing below, mounting B inserts the screw rod C in the air bag by cover below the tip, fixes the air bag on the ring that corresponds the headstock with nut D, walk around the annular transparent air bag afterbody of uncovered ellipse through the nylon tape, fix on the headstock with the thread gluing simple structure is compact, reduces patient's disability rate, avoids medical malpractice's emergence to lighten nursing staff's burden, convenience safe in utilization
