Abstract

A spring-biased nasal molding device for presurgical molding of cleft lip deformities, the device having a pair of intra-nasal shaping members for insertion into the nostrils and having an extra-nasal shaping member to be positioned external to the nostrils connected to each intra-nasal shaping member, wherein the intra-nasal and extra-nasal shaping members are brought together by the spring member to mold the nasal anatomy into the desired shape.

Claims (37)

1. A nasal molding device adapted for pre-surgical molding of cleft lip deformities in a patient, said device comprising:

a biasing member composed of a polymer material and comprising a central spring segment, a pair of tubular intra-nasal projecting members having two open ends and a pair of extra-nasal arm members, wherein said intra-nasal projecting members are connected to said central spring segment and said extra-nasal arm members are connected to said intra-nasal projecting members;

a cover member disposed on each of said extra-nasal arm members, the combination of said cover members and said extra-nasal arm members defining a pair of extra-nasal shaping assemblies;

a tubular stent member disposed on each of said intra-nasal projecting members, each said stent member having a hollow core with two open ends, the combination of said stent members and said intra-nasal projecting members defining a pair of intra-nasal shaping assemblies;

wherein said intra-nasal shaping assemblies are adapted to be positioned in the nostrils of the patient having a cleft lip deformity and said extra-nasal shaping assemblies are adapted to be positioned along the alar creases of the patient, such that the tissue of the patient is retained between the intra-nasal shaping assemblies and the extra-nasal shaping assemblies, and

whereby said intra-nasal shaping assemblies are separable by manually flexing said spring segment, and whereby upon release said spring segment brings said intra-nasal shaping assemblies together over an arced pathway.

2. The device of claim 1 , wherein said central spring segment is U-shaped.

3. The device of claim 2 , wherein said intra-nasal projecting members each comprise a base portion and an elongated post portion.

4. The device of claim 3 , wherein said intra-nasal projecting members each further comprise a retention member.

5. The device of claim 2 , wherein each of said stent members comprises a bulbous, radially-projecting body.

6. The device of claim 5 , wherein said radially-projecting bodies are rounded.

7. The device of claim 2 , said biasing member further comprising a pair of helical spring members, wherein said intra-nasal projecting members are connected to said central spring segment by said helical spring members.

8. The device of claim 1 , wherein said intra-nasal projecting members each comprise a base portion and an elongated post portion.

9. The device of claim 8 , wherein said intra-nasal projecting members each further comprise a retention member.

10. The device of claim 8 , said biasing member further comprising a pair of helical spring members, wherein said intra-nasal projecting members are connected to said central spring segment by said helical spring members, each of said base portions of said intra-nasal projecting members comprising a cavity, and said helical spring members being received within said cavities of said base portions of said intra-nasal projecting members.

11. The device of claim 1 , wherein each of said stent members comprises a bulbous, radially-projecting body.

12. The device of claim 11 , wherein said radially-projecting bodies are rounded.

13. The device of claim 1 , said biasing member further comprising a pair of helical spring members, wherein said intra-nasal projecting members are connected to said central spring segment by said helical spring members.

14. A nasal molding device adapted for pre-surgical molding of cleft lip deformities in a patient, said device comprising:

a unitary biasing member composed of a polymer material and comprising a U-shaped central spring segment, a pair of tubular intra-nasal projecting members having two open ends and a pair of extra-nasal arm members, wherein said intra-nasal projecting members are connected to said central spring segment and said extra-nasal arm members are connected to said intra-nasal projecting members;

a cover member disposed on each of said extra-nasal arm members, the combination of said cover members and said extra-nasal arm members defining a pair of extra-nasal shaping assemblies;

a tubular stent member disposed on each of said intra-nasal projecting members, each said stent member having a hollow core with two open ends, the combination of said stent members and said intra-nasal projecting members defining a pair of intra-nasal shaping assemblies;

wherein said intra-nasal shaping assemblies are adapted to be positioned in the nostrils of the patient having a cleft lip deformity and said extra-nasal shaping assemblies are adapted to be positioned along the alar creases of the patient, such that the tissue of the patient is retained between the intra-nasal shaping assemblies and the extra-nasal shaping assemblies, and

whereby said intra-nasal shaping assemblies are separable by manually flexing said spring segment, and whereby upon release said spring segment brings said intra-nasal shaping assemblies together over an arced pathway.

15. The device of claim 14 , wherein said intra-nasal projecting members each comprise a base portion and an elongated post portion, and wherein said extra-nasal arm members are connected to said base portions of said intra-nasal projecting members.

16. The device of claim 15 , said unitary biasing member further comprising a pair of helical spring members, wherein said intra-nasal projecting members are connected to said central spring segment by said helical spring members, each of said base portions of said intra-nasal projecting members comprising a cavity, and said helical spring members being received within said cavities of said base portions of said intra-nasal projecting members.

17. The device of claim 16 , wherein each of said stent members comprises a rounded, bulbous, radially-projecting body.

18. The device of claim 14 , wherein each of said stent members comprises a rounded, bulbous, radially-projecting body.

19. The device of claim 14 , said unitary biasing member further comprising a pair of helical spring members, wherein said intra-nasal projecting members are connected to said central spring segment by said helical spring members.

20. A nasal molding device adapted for pre-surgical molding of cleft lip deformities in a patient, said device comprising:

a biasing member composed of a polymer material and comprising a U-shaped central spring segment, a pair of tubular intra-nasal projecting members having two open ends and a pair of extra-nasal arm members, wherein said intra-nasal projecting members are connected to said central spring segment and said extra-nasal arm members are connected to said intra-nasal projecting members;

a cover member disposed on each of said extra-nasal arm members, the combination of said cover members and said extra-nasal arm members defining a pair of extra-nasal shaping assemblies;

a tubular stent member disposed on each of said intra-nasal projecting members, each of said stent members comprising a hollow core with two open ends and a rounded, bulbous, radially-projecting body, the combination of said stent members and said intra-nasal projecting members defining a pair of intra-nasal shaping assemblies;

wherein said intra-nasal projecting members each comprise a base portion and an elongated post portion, and wherein said extra-nasal arm members are connected to said base portions of said intra-nasal projecting members;

said biasing member further comprising a pair of helical spring members, wherein said intra-nasal projecting members are connected to said central spring segment by said helical spring members, each of said base portions of said intra-nasal projecting members comprising a cavity, and said helical spring members being received within said cavities of said base portions of said intra-nasal projecting members;

wherein said intra-nasal shaping assemblies are adapted to be positioned in the nostrils of the patient having a cleft lip deformity and said extra-nasal shaping assemblies are adapted to be positioned along the alar creases of the patient, such that the tissue of the patient is retained between the intra-nasal shaping assemblies and the extra-nasal shaping assemblies, and

whereby said intra-nasal shaping assemblies are separable by manually flexing said spring segment, and whereby upon release said spring segment brings said intra-nasal shaping assemblies together over an arced pathway.
