Simulated Eyeball Restoring Force Mechanism for Glaucoma Surgery Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current devices for training in ophthalmic surgery lack the ability to reproduce the specific movements and restoring forces required for glaucoma surgery, particularly the rotation of the eyeball and the balancing forces involved, which are essential for simulating the procedures accurately.
Innovation Solution
A device with a simulated-eyeball pedestal and a mechanism generating a restoring force, utilizing magnets or elastic members to allow the simulated eyeball or its retaining member to rotate and return to a normal state, mimicking the human eye's restoring force during glaucoma surgery, enabling accurate simulation of the 5 to 50-degree rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a simulated eyeball is made movable in a device for training in ophthalmic surgery, then the device can simulate cataract surgery procedures, but it cannot reproduce the rotation and restoring force required for glaucoma surgery
Solution Approach 1:
The simulated eyeball is designed to rotate around the vertical axis within a specific angle range (5 to 50 degrees) rather than being fixed or moving only in limited directions. This dynamic rotation capability allows the device to accurately simulate both cataract surgery (normal position) and glaucoma surgery (strabismus position with restoring force), resolving the contradiction between versatility and simulation accuracy for different surgical procedures
2Adaptability or versatility
If the simulated eyeball is allowed to rotate to simulate strabismus position, then glaucoma surgery can be trained, but the restoring force mechanism becomes complex
Solution Approach 1:
A restoring force mechanism is introduced that applies a force opposite to the rotation direction, simulating the natural restoring force of the human eyeball. This counterbalancing mechanism allows the simulated eyeball to rotate to strabismus positions during glaucoma surgery training while automatically returning to the normal position, achieving realistic surgical simulation without overly complex control systems
3Manufacturing precision
If the simulated eyeball rotation angle is limited to 5 to 50 degrees, then realistic glaucoma surgery training is achieved, but the range of motion is restricted
Solution Approach 1:
The rotation mechanism is designed with localized angular constraints specifically for the glaucoma surgery training context, allowing rotation within the clinically relevant range of 5 to 50 degrees. This targeted angular limitation provides realistic surgical training while maintaining sufficient versatility for all necessary glaucoma procedures, demonstrating that precise local control can achieve both accuracy and adaptability

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively reproduces the movements and forces necessary for glaucoma surgery training, providing a more realistic and safe environment for surgeons to practice, reducing the risk of medical errors and enhancing proficiency.
Implementation Method 1
by incorporating a magnet into a simulated eye and embedding an iron ball as a magnetic body in a pedestal, the simulated eye is able to move centered about a point of contact of the magnet and the magnetic body
Implementation Method 2
a device is also known in which a simulated eyeball is pressed against a face model by spring force of a wire
Implementation Method 3
there is a restoring force that returns the eyeball to a normal state, and the eyeball returns to an original position thereof even when rotated by pulling of a thread

AI summary
The present invention addresses the problem of providing a device for training in ophthalmic surgery that can be used for training in glaucoma surgery. The problem can be solved by a device for training in ophthalmic surgery including: a simulated-eyeball pedestal having a recess into which a simulated eyeball can be directly or indirectly inserted; a simulated eyeball insertable into the simulated-eyeball pedestal, or a member for retaining a simulated eyeball that retains a simulated eyeball, the member for retaining the simulated eyeball being insertable into the simulated-eyeball pedestal; and a mechanism for generating a restoring force that generates a force for restoring a position of the simulated eyeball or the simulated-eyeball retaining member toward a normal state with respect to the simulated-eyeball pedestal; the simulated eyeball or the member for retaining the simulated eyeball rotating along the recess of the simulated-eyeball pedestal.
