INTRANASAL SPLINT COMPRISING ANGLED WING STRUCTURE

Abstract

Disclosed is a therapeutic intranasal splint maintaining valve angle by supporting the nasal septum and lateral nasal wall, thus keeping the nasal passage open, and helping to obtain a positive result from performed nose surgery.

Claims

1. An intranasal splint to be placed into a nasal cavity after nose surgeries, maintaining a valve angle by supporting the nasal septum and the lateral nasal wall, thus providing to keep the nasal pasage open, the intranasal splint comprising: a body to support the nasal septum, comprising a concave inner surface to be faced to the nasal septum and a convex outer surface to be faced to the nasal passage, formed between an anterior end, a posterior end, an upper edge and a lower edge; the body having a thickness decreasing while crossing from central part to the anterior end, the posterior end, the upper edge and the lower edge; a wing connected to the upper edge of the body in a region close to the anterior end in a way opening to the lateral by a valve angle (α); maintaining valve angle between the nasal septum and the lateral wall by supporting the lateral nasal wall, and providing to keep the nasal pasage open.

2. The intranasal splint according to claim 1, wherein the valve angle (α) between the body and the wing is between 15° and 90°.

3. The intranasal splint according to claim 1, wherein the intranasal splint is made of medical grade silicone.

4. The intranasal splint according to claim 1, wherein the length between the anterior end and the posterior end is greater than the length between the upper edge and the lower edge.

DETAILED DESCRIPTION OF THE INVENTION

[0040] In this detailed description, the preferred structures of a splint (A) of the invention are described only for a better understanding of the subject.

[0041] The invented intranasal splint (A) supports nasal septum and nasal lateral wall by being fixed to the septum by suturing within the nose after nose surgeries. In this way, it provides to keep the nasal passage open by maintaining the valve angle between the nasal septum and the lateral nasal wall. As the nasal passage remains open, the patient's nasal breathing continues after nose surgery and patient comfort is provided.

[0042] Intranasal splint (A) shown in a representative view in FIG. 1 comprises a body (1) and a wing (2) essentially. The intranasal splint (A) is preferably produced integrally from medical grade silicone by die-casting or three-dimensional printing.

[0043] The body (1) comprises concave inner surface (1.5) facing to the nasal septum and a convex outer surface (1.6) facing to the nasal passage, formed between an anterior end (1.1), a posterior end (1.2), an upper edge (1.3) and a lower edge (1.4).

[0044] Thichkness of the body (1) tapers while crossing from central part (1.7) to the anterior end (1.1), the posterior end (1.2), the upper edge (1.3) and the lower edge (1.4). The body (1) is made of medical silicone with enough degree of hardness to protect the forms of concave inner surface (1.5) and the convex outer surface (1.6). Thanks to the concave and convex surfaces in horizontal and vertical axises and the central part (1.7) of the body (1) which is thicker than the ends and edges; a surface tension occurs at the posterior end (1.2) towards the septum when the intranasal splint (A) is being fixed with suture to the nasal septum and this tension prevents curling of the posterior end (1.2) towards to the lateral. Thus, each part of the body (1) applies pressure to the nasal septum. Thanks to the pressure occurred development of nasal septal hematoma is prevented.

[0045] The length between the anterior end (1.1) and the posterior end (1.2) of the body (1) is greater than the length between the upper edge (1.3) and the lower edge (1.4). In this way, the intranasal splint (A) can support a large portion of the nasal septum. The anterior end (1.1) and the posterior end (1.2) of the body (1) is preferably formed rounded.

[0046] The wing (2) is integrally connected (continuous) to the upper edge (1.3) of the body (1) from a region close to the front end (1.1) in a way opening to the lateral by a valve angle (α). The wing (2) supports the lateral wall upwardly, thus maintains the valve angle between the nasal septum and the lateral nasal wall and provides keeping nasal passage open.

[0047] The wing (2) is also made of medical silicone with enough degree of hardness to protect the desired valve angle (α).

[0048] The valve angle (α) between the wing (2) and the body (1) is preferably between 15 and 90 degrees.

[0049] Intranasal splints (A) are used as pairs being placed in the right and left nasal cavity. Right and left intranasal splints (A) are mirror images of each other. The bodies (1) and the wings (2) can be cut to the desired size and applied to the patient's nose in appropriate size. Both intranasal splints (A) are inserted into the nose postoperatively and the bodies (1) are fixed with suture to the nasal septum (FIG. 6a-6b). Fixed bodies (1) provide support by forming pressure onto the nasal septum. Thus, after nose surgeries formation of complications such as bleeding, septal hematoma and adhesion are prevented in postoperative period. When the bodies (1) are being fixed to the septum, thanks to the concave/convex surfaces, the posterior ends (1.2) apply enough pressure on the nasal septum so curling to the lateral does not occur. However, the wings (2) support the lateral nasal wall from below and keeps the valve angle (α) wide so that the nasal passage remains open. Thus, in the postoperative period, the patient can continue breathing through the nose.
