Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to a nasal septum auxiliary supporter. Background Art

[0002] Due to the influence of race and region, the development of nasal septum in East Asians and Caucasians is significantly different (relative to Caucasians, the nasal septum is poorly developed). The clinical manifestations are insufficient nasal dorsum length, insufficient support of the nose tip, and displacement of the subnasal point to the side and back of the head, which leads to nasal-facial imbalance, poor proportion of the three courts and five eyes, protrusion of the upper lip, and retraction of the columella. Therefore, various nasal septum extensions are needed to extend the length of the nasal septum (in the horizontal and vertical directions) in rhinoplasty for East Asians to solve the above problems. In addition, some congenital defects or deformities of the nasal septum and ventilation dysfunction all require reconstruction or correction of the nasal septum. In terms of anatomical surgery, it usually includes making an incision at the edge of the nostril, using vascular forceps to reach into the nose tip, nasal dorsum, nasal root and other parts for skin separation, anatomical separation of the nasal septum cartilage, correction, extension, support, fixation or reconstruction, and finally tissue reduction and suture. During the operation, ear cartilage or rib cartilage may be used as implant materials to strengthen the nasal septum. However, the use of ear cartilage or rib cartilage as implant materials to extend support or reconstruct the nasal septum is complicated (see figure), and the implant may deform and absorb, resulting in poor long-term results.

[0003] Application number: 2021228831001 discloses a nasal stent, including a first guard plate, the inner side of which is fixedly connected with a card plate. Advantages of the utility model: the stent is a whole piece of material on each side (divided into a first guard plate, a second guard plate and a card plate fixed on the left and right sides), and the middle is carved along the caudal end, front edge and nasal spine of the nasal septum, and molded into a structure that is completely connected and engaged with it. The whole pieces of material on the left and right sides and the structure in the middle are fixed in vitro as an integrated card seat structure, which is directly carded onto the caudal end, front edge and nasal spine of the nasal septum. No fixation is required or only a simple fixation with one needle is required, less mucosa needs to be separated and less damage; little impact on physiological function; less seesaw deformity and penetration of mucosa; strong support and stability; evenly dispersed points of force; minimized operating costs and subsequent repair costs; simple operation, easy to learn and control, and easy to promote and apply.

[0004] The above technical solution still has the following disadvantages: 1. The bracket and the base are not integrally formed and will not be stable just by snapping together. Even if the snap-fitting part is sutured, the fixation effect is limited (the fixation effect of only one fixed point is far inferior to the costal cartilage triangle fixation), so the long-term effect is poor; 2. Artificial materials are implanted but lack effective drainage, and the healing time is long; 3. This design cannot be assembled in vitro and then implanted into the body, and deep suture fixation must be performed, which is complicated to operate and inconvenient to use.

[0005] Application number: 202120836707.1 Application number: 202121536110.1 Application number: 202223108989.7 The public solutions can only solve the problem of extending the columella and support, but cannot solve the problem of extending the nasal septum in the horizontal direction; and they are all split-type, and the combination and fixation are complicated; and they are all fixed at a single point, and the fixed support effect is poor.

[0006] Application number: 202122881387.4 The public solution is a split solution for nasal dorsum support and columella support. The entire surgical procedure is no different from traditional surgery and has no advantages. Utility Model Content
