Sialendoscopy Training Model with Scalable Duct Anatomy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical technologies lack a model to simulate salivary duct structures, hindering effective visualization and training for sialendoscopy procedures due to the small size of salivary ducts and the complexity of conditions encountered during treatment.
Innovation Solution
A demonstration apparatus comprising a support structure, an insert structure, and a duct structure that mimics normal and non-normal salivary ducts, including features like enlarged or reduced diameters and simulated stones, to simulate various anatomical conditions and facilitate training with sialendoscopy devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sialendoscopy procedures are performed in actual salivary ducts, then treatment can be provided, but the small size of the duct makes visualization and training difficult
Solution Approach 1:
The patent creates a scaled-up duplicate model of the salivary duct system that replicates all anatomical features including strictures, stones, and bifurcations. This copy allows practitioners to practice sialendoscopy procedures with proper visualization without the constraints of the actual small duct size, directly resolving the contradiction between needing accurate representation and having sufficient space for training and observation.
2Reliability
If real salivary ducts are used for training, then authentic anatomical conditions can be studied, but effective training tools are lacking due to the complexity and small size
Solution Approach 1:
The model creates a reliable anatomical copy that maintains authentic structural features including strictures, stones, and bifurcations while scaling up the dimensions to enable effective training operations. This allows practitioners to study genuine anatomical conditions with improved ease of manipulation and visualization compared to actual ducts.
Solution Approach 2:
The patent changes the physical parameters of the duct model by scaling up dimensions while maintaining anatomical proportions. This parameter transformation preserves the reliability of anatomical representation while improving ease of operation for training purposes, allowing larger instruments and better visualization without compromising anatomical accuracy.
3Productivity
If minimally invasive procedures are performed in actual ducts, then patient benefit is achieved, but practitioners lack effective training tools to master these techniques
Solution Approach 1:
The patent creates a versatile training copy that can accommodate various sialendoscopy procedures including wire insertion, dilation, and stone removal. This duplicate model provides the adaptability needed for comprehensive training while maintaining the anatomical fidelity required to prepare practitioners for effective clinical procedures, resolving the contradiction between procedure efficacy and training capability.

AI summary
Models, kits and methods useful in the demonstration of sialendoscopy devices and techniques are described. An exemplary demonstration apparatus comprises a support structure, an insert structure contacting the support structure, and a duct structure contacting the insert structure. The insert structure has a top surface defining a first opening and a bottom surface defining a second opening, and defines a channel with a first end in communication with the first opening and a second end in communication with the second opening. The duct structure comprises an elongate tubular member and has a first end in fluid communication with the first opening of the insert member, a second end, and defines a lumen extending from the first end to the second end. A portion of the duct structure is releasably disposed within the channel defined by the insert structure.
