Description

A fixation device that can maintain the shape of the cranio-auricular groove

Technical field

The invention relates to the technical field of medical auxiliary devices, and is a fixation device that can maintain the shape of the cranial auricular groove.

Background technique

Cranioauricular groove reconstruction surgery is a surgical method commonly used to treat congenital ear malformations and other ear repairs. Due to the unique anatomical characteristics of the ear, after the postauricular skin graft survives, it is freed in the postcranial area where it transitions from the postauricle to the postauricular area. During the process of advancing skin flap wounds and skin scar tissue formation, skin contracture and scar hyperplasia may gradually occur. Because the scar tissue is hard and lacks the elasticity of normal skin, it may cause uneven growth in the cranio-auricular groove area. The pulling force causes the angle of the cranial auricular sulcus to become shallower, thus affecting the angle and shape of the cranial auricular sulcus. In order to reduce or avoid this situation, it is necessary to embed an external fixator stent with a certain cranio-auricular groove angle behind the ear and behind the skull in the early stage of scar formation to prevent scar formation and maintain good postoperative shape.

Currently, although there are some auxiliary devices for postoperative recovery on the market, such as back-of-the-ear mold compression devices, these devices often have some limitations. For example, it is uncomfortable for patients to wear, the pressure is uneven, and it cannot completely resist the contracture or proliferation of scars in the cranio-auricular groove area. Therefore, through scientific design and material selection, how to maintain the stable shape of the cranio-auricular groove after surgery, provide continuous and stable support, reduce the formation of postcranial skin scars, and improve the quality of postoperative recovery of patients has become an urgent solution.
