Endoscopic Surgery Trainer With 4-DOF Organ Position Simulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surgical training apparatuses for endoscopic surgery only simulate parts of the body and cannot provide training for actual surgical procedures due to their limited simulation capabilities.
Innovation Solution
An endoscopic surgery training apparatus with a housing, a holder, a driving part, and a controller that allows for a four-degree-of-freedom movement of a training target member to simulate specific parts of an organ, enabling realistic surgical training.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional surgical training apparatuses use simple body part models, then the device complexity is low, but the training realism and surgical skill development are insufficient
Solution Approach 1:
The training apparatus employs a robotic arm with multiple degrees of freedom that can dynamically position and orient the training target member throughout the training space, transforming a static model into a dynamic simulation system that replicates actual surgical conditions
Solution Approach 2:
The patent replaces simple mechanical positioning with a robotic manipulation system controlled by a controller, using automated mechanical substitution to achieve precise positioning and realistic organ movement simulation without requiring complex manual adjustment mechanisms
2Adaptability or versatility
If the training apparatus provides only observation training, then the device complexity is low, but the surgical procedure training capability is lacking
Solution Approach 1:
The training apparatus is designed to perform multiple training functions including observation, manipulation, and surgical procedure practice through a single integrated system with a movable training target member that can simulate various organ positions and configurations
Solution Approach 2:
The robotic arm acts as an intermediary between the operator and the training target member, enabling sophisticated surgical procedure training by mediating the interaction between the user's actions and the simulated organ responses
3Adaptability or versatility
If the training target member is fixed in position, then the ease of operation is high, but the ability to simulate specific organ positions is limited
Solution Approach 1:
The training target member is transformed from a fixed position to a dynamically movable position through robotic arm actuation, enabling the system to adapt to various organ positions and training scenarios while maintaining ease of operation through automated control

AI summary
An endoscopic surgery training apparatus is disclosed. The endoscopic surgery training apparatus according to an embodiment of the present invention may include a housing including a training space formed inside for training a surgery; a holder configured to fix a training target member; a driving part including a holder support member to which the holder is coupled, and configured to change a position of the holder coupled to the holder support member within the training space through at least one degree-of-freedom movement so as to change a training target member fixed to the holder to a specific simulation position of an organ for training within the training space; a channel forming part formed in the housing so as to form an entry path of an endoscopic device entering the training space from the outside; and a controller for controlling the driving part.
