Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current training methods for cataract, glaucoma, and corneal transplantation surgeries face challenges such as anatomical discrepancies, limited realism, and ethical concerns, particularly in using animal eyes, which hinder effective surgical skill development and increase the risk of complications.
Innovation Solution
A simulator using polysiloxane polymers to create a synthetic model with anatomically accurate structures, including a cornea, iris, anterior and posterior capsules, and ocular mobility, simulating surgical steps like capsulorhexis and hydrodissection, while being compatible with surgical equipment and allowing for cost-effective training.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If animal eyes are used for training, then anatomical similarity is improved, but ethical concerns and logistical complexity increase
Solution Approach 1:
The patent creates a synthetic model that copies the essential anatomical features of the human eye (cornea, anterior chamber, cataract, posterior capsule) using artificial materials, eliminating the need for animal eyes while maintaining training value
Solution Approach 2:
The patent changes the material parameters from biological (animal eye) to synthetic (polysiloxane polymers with specific viscosity and elasticity), achieving similar mechanical properties without the logistical burdens of biological specimens
2Strength
If rigid material is used for the cornea, then structural stability is improved, but surgical incision training realism deteriorates
Solution Approach 1:
The patent applies different material properties to different parts of the cornea - the overall structure maintains stability while the surface layer has appropriate elasticity and softness for realistic incision training
Solution Approach 2:
The patent uses composite material construction where polysiloxane polymers provide both structural stability and surface properties suitable for surgical incision practice
3Strength
If non-soluble synthetic material is used for the cataract, then structural integrity is improved, but equipment damage risk increases
Solution Approach 1:
The patent changes the material parameter from non-soluble to water-soluble polysiloxane polymers, allowing the cataract material to dissolve after use and preventing damage to phacoemulsification equipment while maintaining structural integrity during training
4Stability of the object's composition
If fixed ocular structures are used in the model, then model stability is improved, but ocular mobility simulation deteriorates
Solution Approach 1:
The patent introduces dynamic elements to the model, allowing the ocular structures to move and respond to pressure changes, simulating the 'surge' phenomenon and improving realism while maintaining overall model stability
