Surgical Device Positioning via Physiological Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical devices face challenges during procedures due to anatomical movements, leading to improper positioning and incomplete insertions, as they fail to synchronize with physiological changes such as heartbeats or breathing, resulting in imprecise anatomical state determination.
Innovation Solution
Systems and methods that adjust and synchronize the position of medical devices relative to anatomy by using data on anatomical movements, employing sensors and computing systems to maintain a fixed position or perform interventions during specific anatomical states, such as using probes and fixtures that move in synchronization with the anatomy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the medical device is manually positioned relative to the anatomy, then the physician can perform tasks manually, but the device position becomes inconsistent due to anatomical movements such as heartbeats
Solution Approach 1:
The system continuously monitors anatomical position using sensors (e.g., optical, electromagnetic) and feeds this information back to the control system, which automatically adjusts the medical device position to maintain consistent alignment with the target anatomy despite physiological movements
Solution Approach 2:
The medical device positioning system transitions from static manual positioning to dynamic automated adjustment, where the device position is continuously modified in real-time based on detected anatomical movements, enabling the system to adapt to changing physiological conditions
2Reliability
If the physician attempts to time a movement action to correspond with a specific physiological state, then the intervention can be synchronized with anatomy, but the time delay and inconsistent nature of brain pulsations result in incomplete implantation
Solution Approach 1:
The system detects upcoming physiological states (such as the peak of a brain pulse) in advance using predictive algorithms based on rhythmic patterns, and pre-positions the medical device or pre-loads the insertion mechanism so that the actual implantation occurs at the optimal moment without time delay
Solution Approach 2:
The system replaces manual timing and triggering mechanisms with automated electronic control systems that use sensors and processors to detect, analyze, and respond to physiological signals, eliminating the time delays and inconsistencies associated with manual operation
3Stability of the object's composition
If the physician inhibits the change in physiological state by fixing the anatomy or arresting physiological function, then anatomical movements are restrained, but patient safety and physiological stability are compromised
Solution Approach 1:
The system allows the anatomy to move naturally according to its own physiological rhythms while the medical device automatically compensates for these movements, eliminating the need for external intervention to restrain or arrest physiological functions, thereby maintaining patient safety and physiological stability
Data Source
AI summary
Systems and methods are configured to synchronize a medical device intervention wherein the anatomy moves or changes shape relative to the medical device. A medical device is positioned relative to anatomy. Data is then obtained regarding a position of the anatomy. The data is used to synchronize a position of the medical device relative to the anatomy such as to maintain a relative position between the medical device and the anatomy such as a specific portion of the anatomy.
