Nasal Cast Bender Symmetric Shaping and Tissue Retraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During rhinoplasty, the shaping and positioning of external nasal casts are visually controlled by surgeons, leading to potential crooked or undesirable nose shapes, resulting in unsatisfied patients, as there is no standard device to ensure the correctness of the cast's shape and positioning.
Innovation Solution
A nasal cast bender with a base and a protruding handle and bending surface, configured to shape external nasal casts symmetrically, allowing for precise shaping before application, and can also be used as a weighted retractor to manage nasal skin and soft tissue during surgery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If visual control by surgeon is used for shaping nasal cast, then flexibility in shaping is improved, but manufacturing precision of cast shape deteriorates
Solution Approach 1:
The patent introduces a nasal cast bender as an intermediary device between the surgeon's visual control and the nasal cast shaping process. This device provides standardized shaping surfaces and geometric guides that ensure precise and symmetric casting while maintaining surgeon control over the final shape.
Solution Approach 2:
The patent employs parameter changes by providing nasal cast benders with different curvature radii, angles, and geometric profiles. These varying parameters allow surgeons to achieve different nasal shapes and corrections while maintaining manufacturing precision through standardized tooling.
2Adaptability or versatility
If multiple separate devices are used for cast shaping and tissue retraction, then versatility is improved, but device complexity deteriorates
Solution Approach 1:
The patent applies universality by designing the nasal cast bender to perform multiple functions: shaping the nasal cast, retracting nasal skin and soft tissue, and providing geometric guidance. This multi-functional approach reduces the number of separate devices needed while maintaining versatility in surgical procedures.
Solution Approach 2:
The patent merges previously separate functions (cast shaping and tissue retraction) into a single integrated device. The nasal cast bender combines shaping surfaces with retraction capabilities, simplifying the surgical workflow and reducing device complexity.

AI summary
Embodiments relate generally to systems and methods for shaping an external nasal cast. A nasal cast bender may comprise a base; and a protrusion protruding upwards from the base portion, wherein the protrusion comprises a handle and a bending surface comprising a convex profile; wherein the bending surface is configured to shape an external nasal cast.
