Rotatable Prism Camera Scope for Variable Field of View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional endoscopes require frequent tip changes to adjust the field of view, leading to surgical delays and potential tissue damage, as surgeons must withdraw the scope and reinsert different tips to achieve desired angles, which is undesirable and less than ideal.
Innovation Solution
A system with a 4K image sensor and a prism that allows for changing the angle of view within a single image readout frame using interface elements, enabling the selection of specific one thousand pixel by one thousand pixel arrays to provide desired angles of view without physical tip changes, using a 50° prism to offset between 30°, 50°, and 70° views.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional endoscopes use physical prisms to direct light, then the field of view can be adjusted, but the scope must be withdrawn and reinserted to change tips, causing surgical delays and potential tissue damage
Solution Approach 1:
The patent applies the dynamics principle by making the prism rotatable within the scope tip, allowing the field of view angle to be changed dynamically during surgery without withdrawing the scope. The prism can rotate between different angular positions (e.g., 0°, 30°, 70°) to provide multiple viewing angles while maintaining a single continuous scope insertion.
Solution Approach 2:
The patent implements universality by designing a single scope tip with a rotatable prism that can provide multiple field of view angles (0°, 30°, 70°). This multi-functional design eliminates the need for multiple separate scope tips, allowing one scope to perform the functions of several different angled scopes.
2Adaptability or versatility
If conventional endoscopes use physical prisms to direct light, then the field of view can be adjusted, but frequent tip changes increase the risk of tissue damage during reinsertion
Solution Approach 1:
The rotatable prism allows dynamic adjustment of the field of view angle without removing the scope from the patient's body. The prism can be rotated to different angular positions while the scope remains in place, eliminating the need for repeated insertions and reductions that could damage delicate tissues.
Solution Approach 2:
The patent applies beforehand cushioning by maintaining the scope in a safe, established position while the prism rotates to provide different viewing angles. This prevents the need for repeated trauma to the tissue from multiple insertions, cushioning the patient from potential harm.
3Adaptability or versatility
If conventional endoscopes require tip changes to adjust field of view, then different angles can be achieved, but the surgical procedure becomes less efficient
Solution Approach 1:
The rotatable prism enables dynamic switching between different field of view angles (0°, 30°, 70°) during the surgical procedure. The surgeon can adjust the viewing angle on-demand without interrupting the surgical flow for tip changes, significantly improving surgical efficiency and productivity.
Solution Approach 2:
The patent maintains continuity of useful action by allowing the prism to rotate and adjust the field of view while the scope remains continuously in place. This eliminates interruptions in the surgical procedure, keeping the useful surgical action continuous rather than fragmented by repeated insertions and reductions.
4Ease of operation
If conventional endoscopes use fixed angle tips, then the scope structure is simple, but the surgeon cannot adjust the field of view without changing tips
Solution Approach 1:
The patent introduces a rotatable prism mechanism that adds dynamic adjustability to the scope tip. While this increases device complexity compared to fixed-angle tips, it provides the surgeon with ease of operation by allowing field of view adjustment through simple prism rotation rather than requiring tip changes.
Solution Approach 2:
The rotatable prism acts as an intermediary element between the fixed scope body and the variable field of view requirement. This single movable component provides multiple viewing angles without requiring multiple complete scope tips, balancing the trade-off between device complexity and ease of operation.
