Description

Technical Field

[0001] This utility model belongs to the field of ear reconstruction technology and relates to an adjustable postauricular brace that resists scarring. Background Technology

[0002] Both ear reconstruction and postauricular skin grafting result in patchy scars, which are prone to scar hyperplasia and contracture later on, leading to deformation of the reconstructed auricle and severely affecting the surgical outcome. Pressure therapy is the first-line treatment for preventing and treating scar contracture; however, due to the unique contour structure of the auricle, it is difficult to maintain effective pressure at the scar site.

[0003] Therefore, there is an urgent need in the market for a postauricular anti-scarring brace that can be used after ear reconstruction and postauricular skin grafting. Utility Model Content

[0004] To address the shortcomings of the aforementioned technologies, the purpose of this invention is to provide a brace that maintains the stability of the cranioauricular distance after surgery and resists scarring.

[0005] This utility model proposes an adjustable postauricular brace for scar prevention, comprising: a shaping clip and an elastic clip; wherein,

[0006] The shaping clip includes: a postauricular block and an auricular block; the postauricular block and the auricular block are connected by an elastic clip in the middle;

[0007] The elastic clips apply pressure to the postauricular block and the auricular block, respectively.

[0008] Preferably, both the back ear block and the auricular block have a silicone gel coating on the side that contacts the skin.

[0009] Preferably, the shaped clamp and the elastic clamp are fixed together by a medical adhesive material.

[0010] In this invention, the shaping clamp is made of thermoplastic material, which can be shaped according to the user's individual needs after heating.

[0011] Preferably, the elastic clip is provided with a flexible adjustable rod, which is made of a flexible material and can fit snugly behind the ear. The flexible adjustable rod has a telescopic mechanism; preferably, the telescopic distance is 2-4 mm.

[0012] Preferably, the flexible adjustable rod is further provided with an ear hook, which is used to suspend the brace behind the ear.

[0013] Preferably, the side of the shaping clip that adheres to the skin may also be provided with a removable double-sided adhesive scar dressing.

[0014] Preferably, the support is provided with multiple shaping clamps and multiple corresponding elastic clamps; the elastic clamps are connected in sequence.

[0015] Preferably, the pressure applied by the elastic clamp is adjustable.

[0016] The orthosis proposed in this invention uses elastic clips in conjunction with shaping clips to achieve continuous and effective pressure. The main body of the orthosis, the shaping clip, uses a polymer splint that is malleable at low temperatures, allowing for personalized customization according to the patient's auricle shape and reshaping based on changes in auricle shape during regular follow-ups. The shaping splint has sufficient hardness and shape at room temperature to reliably maintain the cranioauricular distance and prevent the reconstructed auricle from retracting or collapsing. The shaping clip and the elastic clip are connected by an adhesive unit. The entire orthosis consists of a silicone gel layer, a polymer splint layer, and a medical adhesive material layer, forming a sandwich-like structure from the inside out, enabling movable fixation and replaceable components.

[0017] This invention can produce a continuous and effective pressure effect on scars; the pressure can be adjusted according to the severity of the scar; this invention is customized according to the shape of the patient's auricle, which can effectively maintain the distance between the skull and ear and prevent the reconstructed auricle from shrinking and collapsing; the brace of this invention is movable and fixed to the auricle, and can be removed daily; it is small in size, easy to wear, and the parts are replaceable.

[0028] Example 1

[0029] like Figure 1 As shown, the adjustable postauricular brace for scar prevention in this embodiment consists of two parts: a postauricular block and an auricular block. The postauricular block and the auricular block are connected by an elastic clip, which allows adjustment of the opening angle and force of the two parts. One side of the brace has a silicone gel coating that forms a physical protection on the skin surface and has anti-scarring properties. It has a certain degree of adhesiveness and can be directly applied to the skin behind the ear and the auricular helix. The other side has medical double-sided adhesive material for bonding the polymer clip to the fixed end of the elastic clip.

[0030] When using the brace in this embodiment, first soak it in hot water at 65-70°C. After the shaping clip softens, it can be cut to any size. Then place it on the user's temporal bone and behind the ear, press it firmly, and remove it after it cools down to room temperature and hardens. Gently press the shaping clip to reduce its opening angle and place it behind the ear. After releasing it, use the elastic clip to restore the opening angle of the shaping clip and fix it to the skin and behind the ear.

[0031] The silicone gel coating used in this embodiment is chemically stable, does not fail after brief immersion in hot water, and can maintain its stickiness for at least 6 months.

[0032] Example 2

[0033] The adjustable postauricular brace for scarring in this embodiment differs from that in Embodiment 1 in that, as... Figure 4 As shown, the elastic clip is equipped with a flexible adjustable rod. The flexible adjustable rod is tough and can completely fit the surface of the auricle. The flexible adjustable rod is also equipped with an ear hook.

[0034] When using the brace in this embodiment, first soak it in hot water at 65-70°C. After the shaping clip softens, place it on the user's temporal bone and behind the ear, press it firmly, and remove it after it cools down to room temperature and hardens. Then, gently press the shaping clip to reduce its opening angle and place it behind the ear. Hook it on the ear and release it. Then, use the elastic clip to restore the opening angle of the shaping clip and fix it to the skin and behind the ear.

[0035] Example 3

[0036] The adjustable postauricular brace for scarring in this embodiment differs from that in Embodiment 2 in that, as... Figure 5 As shown, the flexible adjustable rod is telescopic, and in this embodiment, the telescopic adjustment range is 2-4cm, which the user can adjust according to their own situation.

[0037] Example 4

[0038] The adjustable postauricular brace for scarring in this embodiment differs from that in Embodiment 2 in that, as... Figure 6 As shown, the size of the shaping clips and elastic clips is reduced, and there are multiple shaping clips. The zoned design allows different pressures to be applied to different tissue areas.

[0039] When using the brace in this embodiment, first soak it in hot water at 65-70°C. After the shaping clip softens, place it on the user's temporal bone and behind the ear, press it firmly, and remove it after it cools down to room temperature and hardens. Then, gently press the shaping clip to reduce its opening angle and place it behind the ear. After releasing it, use the elastic clip to restore the opening angle of the shaping clip and fix it to the skin and behind the ear.

[0040] Example 5

[0041] The adjustable postauricular brace for scarring in this embodiment differs from that in Embodiment 1 in that the pressure of the elastic clip is adjustable, allowing the user to adjust it according to their own needs. A removable, double-sided adhesive scar patch can also be attached to the shaping clip in this embodiment to compensate for the potential decrease in the adhesiveness of the silicone gel coating due to long-term use. The scar patch is approximately 1 mm thick.

[0042] The scope of protection of this utility model is not limited to the above embodiments. Any variations and advantages that can be conceived by those skilled in the art without departing from the spirit and scope of the utility model are included in this utility model and are protected by the appended claims.
