Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an effective training system to assess and improve the cognitive and psychomotor skills of surgeons performing laparoscopic surgery, as inadequate skills can lead to patient discomfort due to complications like bile duct injuries.
Innovation Solution
A laparoscopic skills training system comprising a trainer platform assembly with a base, target arrays, and accessory kits for simulating various surgical tasks, including endoscope use, knot tying, and precision cutting, to assess and enhance surgical dexterity and competence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a comprehensive training system with multiple components (trainer platform, target arrays, accessory kits) is implemented, then surgical skill assessment and training effectiveness are improved, but device complexity increases
Solution Approach 1:
The training system is divided into distinct modular components: a trainer platform assembly with base and supports, interchangeable target arrays with different surgical scenarios, and accessory kits containing various surgical instruments. This segmentation allows each component to be optimized independently while maintaining overall system reliability for surgical skill assessment.
Solution Approach 2:
The trainer platform assembly serves multiple functions: it supports various target arrays for different surgical procedures, accommodates multiple accessory kits with different instruments, and provides a standardized base for consistent skill assessment across diverse surgical tasks. This multi-functionality improves assessment reliability without proportionally increasing complexity.
2Manufacturing precision
If multiple target arrays with protruding targets at various angles are provided, then dexterity training precision is improved, but manufacturing complexity increases
Solution Approach 1:
The target arrays are pre-manufactured with protruding targets positioned at specific angles and locations on the planar surface. This preliminary positioning ensures precise dexterity training scenarios without requiring complex assembly procedures, as the targets are already correctly oriented when the array is attached to the base.
Solution Approach 2:
Multiple target arrays can be manufactured as identical or variant copies, each with pre-defined target configurations. This allows precise replication of surgical scenarios across different training sessions and practitioners, maintaining manufacturing precision while simplifying production through standardized copying processes.
