Dermal Therapy Handpiece Projection for Real-Time Parameter Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dermal therapy hand pieces face a challenge in balancing sufficient and insufficient or excessive treatment due to factors like skin temperature, excitation frequency, and fluence, with clinicians having difficulty in monitoring these parameters while guiding the hand piece.
Innovation Solution
Integration of a projector onto the hand piece to project therapeutic parameters onto the skin, combined with a camera and image processor for real-time feedback and lesion highlighting, allowing clinicians to focus on treatment alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the clinician guides the hand piece while monitoring treatment parameters, then treatment precision is improved, but the clinician's attention is divided and monitoring effectiveness deteriorates
Solution Approach 1:
The patent introduces an intermediary system consisting of a camera, processor, and display that mediates between the treatment parameters and the clinician. The camera captures images of the treatment area, the processor analyzes the images and extracts parameter information, and the display presents this information to the clinician, allowing monitoring without direct visual attention to the console
Solution Approach 2:
The system creates a visual copy of the treatment area and treatment parameters through imaging and display. Instead of requiring the clinician to look at the actual console readings, the system projects a copied visual representation of the treatment information onto the treatment area or displays it in the clinician's field of view
2Reliability
If treatment parameters are monitored in real-time, then treatment safety is improved, but device complexity increases
Solution Approach 1:
The hand piece is designed with multi-functionality, integrating the camera, processor, and display capabilities into the existing treatment device. This allows the same device to perform both the primary treatment function and the monitoring function, reducing the need for separate monitoring equipment and minimizing additional complexity
Solution Approach 2:
The system implements self-service monitoring where the hand piece automatically captures images, processes the data, and displays information without requiring external monitoring equipment or additional manual measurement tools. The treatment device serves its own monitoring needs
Data Source
AI summary
A hand piece for dermal therapy is provided that includes a projector configured to project digital information onto the skin of the patient. A clinician may thus monitor the digital information to confirm that the proper therapy parameters are being used or to adjust the dermal therapy based upon the therapy parameters including in the digital information. In addition, the hand piece includes a camera so that image processing may be used to identify features such as a lesion within a treatment area on the skin of the patient. Based on this image processing, the projector may then selectively illuminate the lesion.
