Solution Overview
Problem
Existing abdominal cavity simulators are limited in their ability to provide diverse and realistic training for various surgical procedures beyond laparoscopic surgery and are cumbersome and expensive to manufacture in a foldable, portable form.
Innovation Solution
A modular abdominal cavity simulator design featuring a pedestal with adjustable fixing portions and a pneumoperitoneum cover that can be easily assembled, disassembled, and folded, allowing for the attachment of diverse organ model fixtures and facilitating storage and portability, with a configuration that includes magnets and T-shaped grooves for stability and secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the simulator is made foldable to improve portability, then ease of storage and carrying is improved, but manufacturing cost increases
Solution Approach 1:
The simulator is divided into multiple separable components including a foldable outer shell, detachable organ models, and modular fixing mechanisms. This segmentation allows the simulator to be folded into a compact state for storage and transport while using simple, cost-effective manufacturing methods for each individual component.
2Reliability
If the simulator precisely reproduces everything in the body cavity to improve training realism, then training effectiveness is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
Instead of uniformly reproducing all body cavity features, the simulator focuses on locally reproducing only the specific anatomical structures and textures relevant to the training objective. Different organ models provide different levels of detail according to their importance for the specific surgical procedure being practiced.
Solution Approach 2:
The simulator uses interchangeable organ models and adjustable fixing portions that can accommodate various training scenarios. The same base structure supports different organ configurations, allowing one simulator to serve multiple training purposes without requiring complete reproduction of every possible anatomical variation.
3Reliability
If the simulator is designed for laparoscopic procedure training only, then training specialization is improved, but adaptability to other procedures decreases
Solution Approach 1:
The simulator incorporates interchangeable organ models representing different abdominal organs and configurable fixing portions that can be adjusted to match various surgical approaches. This allows the same simulator platform to effectively train for laparoscopic procedures as well as other surgical techniques by simply changing the organ model configuration.

AI summary
Provided is an abdominal cavity simulator that allows for diverse and realistic procedure training and is easy to store and carry. The simulator is provided with a pedestal that is provided with multiple fixing portions whereto organ model fixtures are mounted; a pneumoperitoneum cover; and two side plate members that provide a space between the pneumoperitoneum cover and the pedestal for allowing the organ model fixture to be arranged therein. A first recess is provided in the pneumoperitoneum cover; a first protrusion and a second protrusion are provided in the side plate members; and a second recess is provided in the pedestal. In a state in which the direction of either the pedestal or a casing has been changed by 180°, the pneumoperitoneum cover and the side plate members can be secured to each other, and the pedestal and the side plate members can be secured to each other.
