Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical training models lack realistic simulation of laparoscopic procedures, particularly in isolating specific steps like suture passing, which requires three-dimensional depth perception and hand-to-hand transfer of instruments, and do not allow for repeatable practice with ease and cost-effectiveness.
Innovation Solution
A surgical training device with a base and plurality of eyelets configured to mimic abdominal anatomy, where a laparoscopic camera provides video feedback, allowing practitioners to practice suturing and suture passing through angled and retractable eyelets, enhancing skill development in a simulated environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional surgical training models are used, then basic surgical skills can be taught, but they fail to provide realistic simulation of laparoscopic procedures and cannot isolate specific steps like suture passing
Solution Approach 1:
The training model divides the surgical procedure into isolated functional components. The base model provides a simplified representation of abdominal anatomy with specific eyelets positioned to simulate tissue layers. This segmentation allows the model to focus on and isolate the suture passing step independently from other surgical tasks, enabling trainees to practice this specific skill repeatedly without distraction.
Solution Approach 2:
The patent extracts the essential elements needed for practicing suture passing from complex surgical procedures. By removing unnecessary anatomical structures and focusing only on the critical components (base, eyelets, and camera system), the model isolates the suture passing step for dedicated practice while maintaining realism through the camera's two-dimensional display.
2Ease of operation
If models simulating laparoscopic procedures are placed in simulated pelvic trainers, then practitioners can practice techniques, but the anatomical model is obscured from direct visualization requiring reliance on two-dimensional video monitors
Solution Approach 1:
The training model incorporates a camera system that provides real-time visual feedback on a two-dimensional display. This feedback mechanism allows trainees to observe their hand movements and instrument manipulation from a different perspective, improving hand-eye coordination while the camera captures the three-dimensional actions that would otherwise be difficult to perceive directly.
Solution Approach 2:
The model transitions from direct three-dimensional visualization to two-dimensional video display, forcing the trainee to develop spatial reasoning skills. The camera angle and display create a dimensional transformation that simulates the actual laparoscopic experience, where the surgeon must interpret three-dimensional tissue structures through a two-dimensional screen.
3Reliability
If extensive training is provided to cover all possible scenarios, then trainee competence is improved, but training time and resource consumption increase significantly
Solution Approach 1:
By segmenting the training into specific isolatable steps like suture passing, the model allows trainees to focus on one skill at a time. This modular approach enables comprehensive training of multiple procedures using the same base model, reducing overall training time compared to requiring separate models for each surgical task.
Solution Approach 2:
The base model is designed with multiple eyelets and adjustable components that can simulate different surgical scenarios and tissue depths. This multi-functionality allows a single model to serve multiple training purposes, reducing the need for multiple specialized models and thereby decreasing training resource consumption.
4Reliability
If realistic anatomical models are used for laparoscopic training, then skill development is enhanced, but model complexity and cost increase
Solution Approach 1:
The model extracts only the essential features needed for practicing suture passing: a base structure with eyelets positioned to represent tissue layers. By removing unnecessary anatomical details while preserving the critical functional elements, the model achieves realism for the specific task without the complexity and cost of complete anatomical replication.
Solution Approach 2:
The model applies local quality by creating realistic tissue simulation only at the specific locations where eyelets are positioned. The base structure provides simplified representation while the eyelet regions offer the necessary complexity for practicing suture passing, balancing realism with simplicity in the areas that matter most for the training objective.

AI summary
A surgical training device is provided. The training device includes a practice model comprising a base with a plurality of eyelets connected to the outer surface of the base. The plurality of eyelets defines at least one predetermined pathway for practicing the passing of at least one needle and suture through the eyelets of the predetermined pathway. Various eyelets are described including angled, flexible, deflectable, interchangeable, retractable, rotatable and ones having apertures of various shapes and sizes. The predetermined pathway is marked with markings on the outer surface of base or with color-coded eyelets. Suture pathways define anatomical pathways as well as differing skill levels. The model provides a platform for practicing hand-to-hand transfer and depth perception among other skills required in laparoscopic procedures.
