Mirrored Robotic Ophthalmic Surgery for One-Sided Reachability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgeons experience discomfort and reachability issues when performing ophthalmic procedures on one side of a patient's body due to their dominant hand positioning, which is not naturally suited for that side, leading to a preference for performing surgeries on the opposite side.
Innovation Solution
A robotic system with imaging and control components that display a mirror image of the patient's body or eye, allowing surgeons to operate on their less-preferred side as if they were operating on their preferred side, using mirrored inputs and outputs to simulate the preferred hand positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a surgeon performs procedures on their less-preferred side, then both eyes can be operated on, but the surgeon experiences discomfort and reachability issues due to dominant hand positioning
Solution Approach 1:
The system inverts the surgical field view through mirror imaging, allowing the surgeon to view and operate on the less-preferred side as if it were the preferred side. The display shows a mirror image of the surgical field, and the robotic system mirrors the surgeon's hand movements, effectively inverting the spatial relationship to eliminate discomfort and reachability issues
Solution Approach 2:
The system creates a virtual copy of the surgical field through mirror imaging. The display shows a mirrored representation of the patient's face and surgical field, allowing the surgeon to interact with a virtual model that replicates the preferred-side geometry, thereby maintaining optimal hand positioning and comfort
2Manufacturing precision
If the surgeon uses their dominant hand for stability positioning, then precision is improved, but the surgeon can only comfortably operate on one side of the patient's body
Solution Approach 1:
The system inverts the spatial configuration of the surgical field through mirror imaging, allowing the surgeon to maintain their preferred dominant-hand positioning even when operating on the less-preferred side. The mirrored display and robotic arm movement inversion ensure that the dominant hand remains in the optimal position for precision while enabling operation on both sides
Solution Approach 2:
The robotic system provides universal functionality by enabling the surgeon to perform procedures on both sides of the patient's body with equal comfort and precision. The system adapts to the surgeon's preferences regardless of which side is being operated on, making the surgical setup universally applicable to both left and right eye procedures

AI summary
Apparatus and methods are described for performing a procedure on a portion of a first side of a body of a patient using one or more tools. An imaging device images the portion of the first side of the patient's body. A display displays a mirror image of the portion of the first side of the patient's body to an operator. One or more control components are be operated by the operator. One or more robotic units hold the one or more tools, each of the one or more robotic units corresponding to a respective control component and mirroring a position of the corresponding control component. A computer processor processes inputs into the each of the control components such as to generate mirrored outputs at the corresponding robotic unit. Other applications are also described.
