Abstract
The invention discloses a shaping expander of double bags, double valves and a three-cavity guide pipe. The shaping expander comprises a bag body comprising the expansion outer bag and the shaping inner bag, an injection valve of which the two valves are connected with the outer bag and the inner bag through guide pipes, the three-cavity guide pipe of which two cavities are connected with the inner bag and the outer bag and one cavity is connected with a draining flushing pipe with peripheral holes of the outer bag and the like. The outer bag body can still be provided with a foot process. The expander is put under the skin from a small incision, afterwards, contents are filled into the outer bag, so that the foot process extends outwards; the outwards-extending foot process can play a role in automatically separating the subcutaneous tissue. Meanwhile, as the bag cavity becomes larger and larger, the corresponding skin soft tissue is expanded along with the bag cavity. When the outer bag expands and the flap reaches a certain area, the contents in the outer bag are pumped out and at the same time, the contents are filled into the inner bag and air outside the bag and under the flap is pumped out to form negative pressure, so that the outer bag and the expanded flap tightly adhere to the surface of the shaping inner bag and the effect of shaping the flap is achieved. Thus, the expanded flap can be utilized more reasonably in the II-stage operation and trauma is reduced.
