Lateral Canthotomy Simulation Device with Replaceable Tendon
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Emergency medical personnel often lack proper training for performing lateral canthotomy and cantholysis, a time-sensitive procedure to treat acute orbital compartment syndrome, especially in remote or military settings where ophthalmologists are unavailable.
Innovation Solution
A simulation device for training emergency eye surgery, including a simulated eye, a base, a skin covering, and a simulated lateral canthal tendon, which allows users to practice lateral canthotomy and cantholysis safely and repeatedly, mimicking the tension and anatomy of the eye area without causing harm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If emergency medical personnel perform lateral canthotomy and cantholysis without proper training, then vision loss may occur, but training opportunities are limited due to lack of simulation devices
Solution Approach 1:
The patent creates a realistic simulation device that copies the anatomical structures of the human eye and surrounding tissues. The simulated eye includes an eyeball, eyelids, lateral canthal tendon, and orbital bone structure that replicate the actual anatomical relationships. This allows trainees to practice lateral canthotomy and cantholysis procedures on a lifelike model without risking patient safety, thereby improving procedural reliability while enabling widespread training availability.
2Measurement precision
If a simulation device uses realistic anatomical structures, then training effectiveness improves, but device complexity increases
Solution Approach 1:
The simulation device is divided into distinct modular components: the orbital bone structure (base), the simulated eyeball, the eyelids, the lateral canthal tendon, and the skin layer. Each component can be independently constructed and assembled. The lateral canthal tendon is attached to the orbital bone and eyeball, allowing it to be selectively cut during training. This segmentation enables realistic anatomical relationships while simplifying manufacturing and assembly processes.
3Productivity
If the simulation device allows repeated practice, then skill development improves, but material durability requirements increase
Solution Approach 1:
The patent designs the lateral canthal tendon and other soft tissue components to be replaceable. After repeated use and cutting exercises, these consumable parts can be discarded and replaced with fresh components, while the durable structural elements (orbital bone, eyeball, eyelid framework) are recovered and reused. This approach enables unlimited training repetitions while maintaining material durability, as the permanent structures are built to withstand repeated assembly and disassembly cycles.

AI summary
Aspects of the present disclosure are directed toward a device for training emergency eye surgery such as lateral canthotomy and cantholysis training. Features of the device may include a simulated eye, a base configured to receive the simulated eye, a simulated skin, an eye displacer, and/or 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.
