On the basis of step C, the handle can be rotated. Since the auxiliary device has covered the upper body of the fetus, this rotation can effectively change the relative position of the shoulder neck and the bony pelvis, which is beneficial to the delivery of the fetus; E. In the process of operation step C and/or step D, use the inflation port to inflate the neck support area, because the connecting piece is made of low-elasticity material, the traction of the connecting piece and the contraction of the contraction area B make the neck support area of the inflation port Expanded into a flared shape, dragging the head of the fetus, facilitating the operations of step C and/or step D; F. When operating step B and/or step C and/or step D, the switch on the clamp arm handle can control the opening or closing of the camera and the LED lamp bead, and the camera can be connected to a display, which is beneficial to the medical staff's operating vision.
