Background
Soft tissue expanders, also called skin soft tissue expanders (hereinafter referred to as expanders), are commonly used in surgical treatment for plastic and repair reconstruction, and are widely used in clinical treatment. The dilator is an instrument designed by utilizing the physiological functions of expanding and increasing the area of skin soft tissues under a certain tension. The increased skin soft tissue obtained after tissue expansion is used for repairing tissue wounds or tissue defects to be treated or reconstructing corresponding tissue organs. The skin soft tissue increased by expansion has similar color, texture or hair as the adjacent skin tissue, and no new defect deformity is generated, so that better shaping, beautifying and repairing reconstruction curative effects are obtained.
Skin soft tissue dilators have been widely used in recent years in reduction surgery, and when a patient is treated with a dilator, the conventional dilator expands the volume of the dilator buried under the skin by injecting physiological saline, inducing skin regeneration, thereby obtaining additional skin. When the patient requires a large flap area, a large amount of saline needs to be injected, so that compression from the weight of the dilator may cause a great burden on the patient and flap necrosis, especially in some pediatric patients. Meanwhile, because of inertia, the dilator filled with a large amount of physiological saline is easy to break when a patient takes a large-scale action.
It is therefore necessary to design a gaseous soft tissue expander for skin expansion.
