[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0017] The special anti-collapse insertion frame for the expansion-type femoral head of the airbag is composed of the air nozzle 01, the elastic cord 02, the airbag 03, the vertical rib 04, the flat rib 05 and the end shell 06. Wherein, the vertical rib 04, the flat rib 05 and the end shell 06 are made of nickel-titanium alloy. The end shell 06 is a pair of spherical crown-shaped shells arranged up and down. On the edge of each end shell 06, there are multiple flat ribs 05 hinged with the end shell 06. The multiple flat ribs 05 are along the edge of the end shell 06. The circumference is evenly distributed, and the extension line of the center line of each flat rib 05 intersects the axis line of the end shell 06 . There is a vertical rib 04 integrated with the flat rib 05 on each flat rib 05, and the cross section of the combination of the flat rib 05 ...
