Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current robot-assisted surgery systems lack a technical monitoring or control mechanism for accurately orienting surgical instruments with respect to a target area, relying on user experience for positioning and orientation of manipulator arms.
Innovation Solution
An apparatus with a positioning device that emits a light beam, connected to a manipulator arm, determines the distance vector between the beam's central axis and a target area defined by coordinates, generating control information to assist in correctly positioning and orienting the instrument unit, allowing for intuitive and precise alignment without requiring a trained medical staff.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a positioning device with light beam and control unit is implemented, then positioning precision and orientation accuracy are improved, but device complexity increases
Solution Approach 1:
A positioning device serving as an intermediary component is introduced between the manipulator arm and the surgical instrument. This positioning device includes a light source that emits a light beam toward the target area, a control unit that receives position information from the manipulator arm and determines distance vectors, and a display unit that provides visual feedback. This intermediary system enables precise positioning and orientation without requiring complex modifications to the entire surgical system.
2Device complexity
If manual positioning based on user experience is used, then device complexity is reduced, but positioning accuracy and reliability deteriorate
Solution Approach 1:
A feedback mechanism is implemented where the control unit continuously receives position information from the manipulator arm, calculates the distance vector between the light beam's central axis and the target area, and provides visual feedback through the display unit. This feedback loop enables real-time monitoring and adjustment of the manipulator arm's position, significantly improving positioning reliability compared to manual positioning based solely on user experience.
3Measurement precision
If automated positioning control is implemented, then positioning precision is improved, but ease of operation decreases
Solution Approach 1:
The positioning device acts as an intelligent intermediary that automates the complex calculations of distance vectors and orientation adjustments while presenting simple visual feedback to the operator. The control unit handles the computationally intensive tasks of receiving manipulator arm position data, calculating optimal positioning parameters, and determining when the light beam is properly aligned with the target area, thereby maintaining operational simplicity despite the sophisticated automated control functions.
