Head Positioner for Retinal Surgery Using Gyroscope Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Patients face challenges in maintaining precise head positioning post-retinal surgery with intravitreal gas or silicone oil tamponade, leading to potential retinal detachment and vision loss due to incorrect positioning, as they struggle to gauge and maintain the required tilt angles.
Innovation Solution
A position sensing system comprising a gyroscope, accelerometer, controller, and alarm, which can be worn on the head to monitor and alert the patient of deviations from prescribed head orientations, ensuring accurate positioning through real-time feedback and adjustable alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If patients wear an eye patch with an arrow to maintain head position, then head positioning accuracy is improved, but patient comfort and compliance deteriorate
Solution Approach 1:
The patent replaces the mechanical eye patch system with an electronic sensing system using accelerometers and gyroscopes to detect head orientation. This substitution eliminates the need for physical patches while providing continuous automated monitoring and feedback, thereby maintaining positioning accuracy while significantly improving patient comfort and compliance.
Solution Approach 2:
The patent implements real-time feedback through audiovisual alerts that notify patients when their head position deviates from the prescribed orientation. This continuous feedback loop enables patients to self-correct their positioning without wearing restrictive patches, resolving the contradiction between measurement precision and ease of operation.
2Measurement precision
If patients frequently check mirror to confirm arrow position, then positioning accuracy is improved, but time consumption and complexity increase
Solution Approach 1:
The patent provides continuous real-time feedback through audiovisual alerts that immediately notify patients of positioning deviations. This eliminates the need for intermittent mirror checks, as the system continuously monitors and alerts patients, thereby maintaining high positioning accuracy while significantly reducing time consumption.
Solution Approach 2:
The patent implements continuous monitoring of head position throughout the day, including during sleep, rather than requiring intermittent manual checks. This continuous action ensures constant positioning accuracy without the time loss associated with frequent mirror verification.
3Reliability
If patients maintain strict head positioning, then surgical outcome is improved, but patient quality of life deteriorates
Solution Approach 1:
The patent enables patients to independently monitor and correct their own head positioning through automated sensing and feedback mechanisms. This self-service capability ensures reliable surgical outcomes while maintaining patient autonomy and quality of life, as patients can make adjustments without external intervention or restrictive devices.
Solution Approach 2:
The real-time audiovisual feedback system allows patients to maintain proper positioning intuitively without constant conscious effort. The system handles the monitoring burden, freeing patients to live normally while ensuring surgical success, thus resolving the contradiction between reliability and ease of operation.
4Ease of operation
If patients remove eye patch for comfort, then patient comfort is improved, but positioning monitoring capability deteriorates
Solution Approach 1:
The patent replaces the mechanical eye patch monitoring system with electronic sensors that can be worn comfortably as head-mounted devices. This substitution maintains continuous positioning monitoring capability while eliminating the discomfort associated with traditional patches, allowing patients to keep the monitoring system in place without removal.

Data Source
AI summary
A position sensing system comprises a position sensor having an accelerometer and a gyroscope, an alarm, and a controller configured to receive data from the position sensor and activate the alarm according to alarm management instructions stored in a memory. In some embodiments, the alarm instructions include a snooze option to allow the user/patient to temporarily deactivate the alarm. The controller is communicably linked to a remote display device configured to display the orientation of the user's body part.
