Actuator Device for Single-Operator Ureteroscopic Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current noninvasive medical procedures, such as ureteroscopic procedures, often require multiple operators due to the complexity of coordinating the scope and retrieval device, leading to communication gaps, movement inefficiencies, and delayed response times.
Innovation Solution
An actuator device with a housing that can be snap-fitted to both a scope and a retrieval device handle, featuring a movable platform and a link assembly that allows for controlled movement of the platform and slider relative to the housing and handle, enabling single-operator control of the procedure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple operators are used to control the scope and retrieval device separately, then each operator can focus on their specific task, but communication gaps and coordination inefficiencies arise
Solution Approach 1:
The actuator device merges the control functions of the scope and retrieval device into a single integrated unit. The housing simultaneously engages with both the scope and retrieval device handle, allowing one operator to control both instruments through a unified interface, eliminating communication gaps while maintaining task specialization through dedicated control mechanisms for each function
Solution Approach 2:
The actuator device serves multiple functions through a single device. It provides both scope control and retrieval device control capabilities, allowing one operator to perform previously multi-operator tasks. The universal design enables switching between different control functions without requiring separate operators or devices
2Ease of operation
If multiple operators control the scope and retrieval device independently, then each operator has direct control, but movement inefficiencies and delayed response times occur
Solution Approach 1:
The actuator device combines scope control and retrieval device control into one integrated system. The housing engages with both instruments simultaneously, and the operator can switch between control functions without coordination delays, improving procedural efficiency while maintaining direct control through the unified interface
Solution Approach 2:
The actuator device provides dynamic control capabilities with movable platforms that can be repositioned along the scope axis. The link assembly with springs and levers enables rapid, responsive movements of both the scope and retrieval device, allowing the operator to quickly adjust positions and respond to procedural needs without the delays associated with multi-operator coordination
3Loss of time
If a single operator controls both scope and retrieval device, then communication gaps and coordination issues are eliminated, but control complexity increases
Solution Approach 1:
The actuator device segments control functions into distinct, manageable components. The housing has separate engagement portions for the scope and retrieval device handle, and the platform can be positioned at different locations to access different control functions. This segmentation allows one operator to manage complex controls through modular, organized interfaces
Solution Approach 2:
The actuator device acts as an intermediary between the operator and both the scope and retrieval device. The housing serves as a mediating structure that simultaneously interfaces with both instruments, translating single-operator inputs into coordinated movements of both devices, thereby simplifying the control interface while maintaining functional complexity
