Immersive 3D Surgical Display With Arm-Based Ergonomic Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional robotic surgical systems have rigid, immovable displays that can lead to user strain, fatigue, and injury due to non-natural manipulation techniques, and existing immersive displays rely solely on head-mounted devices that restrict head movements.
Innovation Solution
An immersive display system with a support arm and housing that provides a three-dimensional view, includes sensors for user interaction and ergonomic positioning, and allows head gestures for control, featuring adjustable eyepieces and sensors for user authentication and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If rigid, immovable displays are used in robotic surgical systems, then device stability is improved, but user comfort and ergonomics deteriorate
Solution Approach 1:
The display is transformed from a static, rigid structure to a dynamic, adjustable one. The support arm with multiple actuatable joints allows the display to move and reposition itself, adapting to different user positions and preferences while maintaining operational stability during use.
Solution Approach 2:
The display system is divided into separable components: the display unit, the support arm with multiple joints, and the mounting mechanism. This segmentation allows independent optimization of each component - the display remains stable when positioned, while the support arm provides ergonomic flexibility.
2Measurement precision
If head-mounted immersive displays are used, then visualization quality is improved, but head movement freedom deteriorates
Solution Approach 1:
The display is extracted from the head-mounted configuration and repositioned on a support arm near the user's head. This removes the constraint of head-wearing while maintaining immersive visualization quality through the eyepiece assemblies and three-dimensional display capabilities.
Solution Approach 2:
The support arm acts as an intermediary between the fixed mounting structure and the user's head position. It provides the necessary flexibility and positioning capability, allowing the display to remain stable while accommodating natural head movements and ergonomics.
3Manufacturing precision
If conventional robotic MIS systems are used, then surgical precision is improved, but surgeon demand and fatigue increase
Solution Approach 1:
The system replaces indirect mechanical manipulation with direct, natural hand movements. The robotic surgical tools are controlled through a user interface that translates natural hand gestures and movements into precise surgical actions, eliminating the need for complex mechanical manipulation techniques.
Solution Approach 2:
The robotic system provides automated assistance for precise surgical movements, reducing the physical and cognitive demand on the surgeon. The system handles the complex coordination and precision requirements, allowing the surgeon to focus on surgical decision-making while experiencing reduced fatigue.

AI summary
An immersive display for use in a robotic surgical system includes a support arm, a housing mounted to the support arm and configured to engage with a face of the user, at least two eyepiece assemblies disposed in the housing and configured to provide a three-dimensional display, and at least one sensor, wherein the sensor enables operation of the robotic surgical system, and wherein the support arm is actuatable to move the housing for ergonomic positioning.
