TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a device for treating external ear scar keloid. BACKGROUND

[0002] External ear scar keloid is a pathological scar that occurs on the skin of the auricle (including the earlobe), which is a benign fibroproliferative neoplasm-like lesion. It is not an ordinary scar, but an excessive and abnormal proliferation caused by an imbalance between collagen synthesis and degradation during wound healing; the external ear is one of the parts of the human body that is prone to lesions and the formation of keloids.

[0009] Further, a gas pipe is arranged on the clamp corresponding to the flat air bag, the gas pipe is communicated with the flat air bag, and the flat air bag is inflated through the gas pipe.

[0010] Further, the adjusting arm comprises a telescopic plate and a telescopic rod, one end of the telescopic plate is detachably connected with the mounting plate, the other end is rotatably connected with the rear end of the telescopic rod, the extended section of the telescopic rod can rotate around the axis of the non-extended section; the extended end of the telescopic rod connected with the first compression member is fixedly connected with the fixed plate; and the extended end of the telescopic rod connected with the second compression member is fixedly connected with the clamp.
