TECHNICAL FIELD
[0001] The utility model relates to medical support technical field, especially ear postoperative three -dimensional shape fixed device. BACKGROUND
[0002] Since the 1950s, Tanzer pioneered modern ear reconstruction technology, ear surgery reconstruction technology has been developing, and the currently used method mainly divides into two categories: (1) skin expansion method and (2) non-skin expansion method.
[0003] And for skin expansion method, according to the area of ear skin expansion, it is divided into: ultra-thin flap expansion method, because the expanded skin can only cover the front of ear support, ear support needs skin grafting to cover, therefore, it is commonly known as "half package";Skin fascia expansion method, because the area of expanded flap tissue can wrap the whole ear support, therefore, it is commonly known as "full package". Whether "half package" or "full package" reconstructed ear can be shaped after the placement of ear support, but in order to improve the appearance of reconstructed ear, it still needs to be repaired again to remove the redundant residual ear tissue. Therefore, skin expansion method needs three operations: one stage: expander implantation, two stages: ear reconstruction, three stages: reconstructed ear trimming.
[0004] However, no matter which ear reconstruction surgery treatment plan, it needs special care for the ear during the whole treatment cycle, and in the past, doctors have carried out individualized treatment according to the individual conditions of patients. There is still a lack of a standardized postoperative ear fixation device to protect the ear from the influence of various adverse factors during the recovery process. For example: maintaining the shape of the reconstructed external ear, preventing displacement, avoiding potential risks such as infection of the wound skin and cartilage of the external ear, hematoma formation, local tissue necrosis, etc.
[0005] At present, the commonly used material for ear postoperative fixation is surgical tape or bandage, which is subject to its own characteristics, can only play a pasting and wrapping role, does not have supporting and fixing function, and has poor air permeability, is easy to stick with wound exudate, breeds bacteria and causes wound infection. Ear postoperative fixation can also use ear cover, which has a single function, only covers the postoperative ear, does not have the function of ear support and fixation, and is insufficient to support the special nursing needs after some complex ear surgery. SUMMARY
[0006] The technical problem to be solved by the utility model is to provide an ear postoperative three-dimensional shape fixed device to solve the problem that the existing ear postoperative fixation material does not have supporting and fixing function, has poor air permeability, is easy to stick with wound exudate, breeds bacteria and causes wound infection.

[0008] An ear postoperative three-dimensional shape holding device, comprising: a protective cover, an arc-shaped protective support and an ear back support;
[0009] The protective cover and the arc-shaped protective support are detachably clamped and connected;
[0010] The ear back support is arranged between the back of the ear of the patient and the skull skin to support the ear and prevent postoperative ear collapse and deformation.
[0011] Compared with the prior art, the ear postoperative three-dimensional shape holding device has at least the following beneficial effects:
[0012] (1) In the utility model, the standardized ear postoperative three-dimensional shape holding device is adopted to protect the ear from being affected by various adverse factors during the recovery process, the ear back support is arranged between the back of the ear of the patient and the skull skin to support the ear and prevent postoperative ear collapse and deformation, and the protective cover covers the ear inside the ear postoperative three-dimensional shape holding device, so that the external ear is prevented from being subjected to external force such as compression and impact, and potential risks such as wound skin infection, cartilage infection, hematoma formation and local tissue necrosis are avoided.
