Rotating Tissue Holder for Endoscopic Training Models
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current organ models for endoscope training and evaluation require actual internal organ tissue for procedures like endoscopic mucous membrane dissection or suturing, which is impractical and limited, as they often rely on animal tissues.
Innovation Solution
An organ model with a tubular basic shape part and a detachable tissue holding part that allows for the secure attachment and rotation of tissue pieces, mimicking the internal organs, enabling diverse training scenarios without the need for actual tissues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If actual internal organ tissue is used for training procedures, then training realism is improved, but availability and reusability deteriorate
Solution Approach 1:
The invention creates a synthetic tissue holding part that copies the essential functional characteristics of actual internal organ tissue without using real biological material. The tissue holding part is designed to provide realistic tactile feedback and structural properties similar to actual tissue, enabling training procedures to be performed on the model repeatedly without consumption or degradation of real biological samples.
2Manufacturing precision
If tissue pieces are securely fixed on the organ model, then procedural training accuracy is improved, but operational flexibility deteriorates
Solution Approach 1:
The tissue holding part incorporates a rotating member that can rotate in the circumferential direction, allowing the tissue piece to be positioned at different orientations. This dynamic capability enables the same tissue holding part to be used for multiple different training scenarios by simply rotating it to the appropriate orientation, thereby maintaining procedural training accuracy while improving operational flexibility.
3Stability of the object's composition
If the organ model uses fixed configuration, then structural stability is improved, but training scenario diversity deteriorates
Solution Approach 1:
The organ model is divided into separate functional components: a basic shape part that provides structural stability and a detachable tissue holding part that can be independently configured. The tissue holding part can be detached and reattached in different orientations or configurations, allowing diverse training scenarios to be implemented on the same stable structural base.
4Adaptability or versatility
If multiple tissue pieces are held for different procedures, then training versatility is improved, but device complexity deteriorates
Solution Approach 1:
The tissue holding part is designed as a universal component that can hold different tissue pieces for various training procedures through rotation. Instead of requiring separate fixation mechanisms for each type of tissue or procedure, the single rotatable tissue holding part can accommodate multiple tissue pieces by rotating to different orientations, thereby providing training versatility without increasing device complexity.

AI summary
An organ model for endoscope includes: a basic shape part formed by imitating a shape of a tubular organ; and a tissue holding part that holds a tissue piece and is detachably provided with respect to the basic shape part. The tissue holding part includes: a main body that is formed in a tubular shape and has a window part communicating with an internal space, on an outer peripheral surface; and a fixing member that fixes the tissue piece on the main body such that at least a portion of the tissue piece overlaps the window part. The main body is rotatable in a circumferential direction of the main body with respect to the basic shape part, in a state where the main body is attached to the basic shape part.
