Lateral Canthotomy Simulation Device with Eye Actuator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Emergency medical personnel often lack proper training for performing lateral canthotomy and cantholysis in remote or combat situations where an ophthalmologist or hospital is unavailable, leading to potential irreversible vision damage due to acute orbital compartment syndrome.
Innovation Solution
A simulation device for training lateral canthotomy and cantholysis, comprising a simulated eye, a base, a skin covering, an anchor, and an eye actuator, which mimics the face and orbit structures, allowing users to practice the procedure safely and effectively without causing harm, with features like preformed incisions and adhesive strips for repeated use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If medical personnel perform lateral canthotomy and cantholysis without proper training in remote situations, then immediate treatment can be provided, but irreversible vision damage may occur due to incorrect procedure performance
Solution Approach 1:
The patent creates a realistic simulation model that copies the anatomical structures of the human eye and surrounding tissues. The simulation includes a globe, eyelids, canthal tendons, and orbital bones arranged to replicate actual human anatomy, allowing trainees to practice the procedure on a lifelike model without risking patient vision.
Solution Approach 2:
The simulation device serves as an intermediary between theoretical knowledge and actual clinical practice. It provides a middle ground where medical personnel can develop and refine their surgical skills in a controlled environment before performing the procedure on real patients, thereby improving both confidence and competence.
2Reliability
If a simulation device is created for training purposes, then procedure accuracy can be improved, but device complexity increases
Solution Approach 1:
The simulation device is divided into distinct modular components: a globe representing the eye, eyelid structures, canthal tendons, and a base representing orbital bones. This segmentation allows each component to be independently constructed and assembled, simplifying the overall design while maintaining anatomical accuracy.
Solution Approach 2:
Different regions of the simulation device have specialized properties tailored to their function. The globe is made from materials with specific optical and tactile properties, the eyelids have flexible characteristics, and the canthal tendons are designed to replicate their actual mechanical behavior. This local optimization of material and structural properties enhances realism without requiring complex systems throughout the entire device.

AI summary
Aspects of the present disclosure are directed toward a device for training emergency eye surgery such as lateral canthotomy and cantholysis training. The device includes a simulated eye, a base configured to receive the simulated eye, a simulated skin, an eye displacer, and a simulated tendon. The simulated skin is configured to attach to the base and at least partially cover the simulated eye, the simulated skin depicting an area immediately surrounding a human eye, and including an eye opening configured to expose at least a portion of the simulated eye through said eye opening when the simulated skin is attached to the base. The eye displacer is configured to displace the simulated eye from a first position to second position, the first position corresponding to an ocular injury and the second position indicating a properly performed ocular surgery.
