Digital Stereo Image Display Device with Quick Release Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital surgical microscopes with head-mounted displays can be ergonomically challenging for surgeons due to weight and difficulty in recognizing three-dimensional images, particularly in prolonged ophthalmology procedures like cataract operations.
Innovation Solution
A digital stereo image display device with a holding arm and quick release interface, allowing for ergonomic positioning and easy attachment to a mount, featuring two digital eyepieces for displaying images from different angles, and incorporating a joint system for adjustable and lockable configurations to facilitate comfortable use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a head-mounted display system is used for digital stereo imaging, then the surgeon can view images from two different angles, but the weight on the surgeon's head becomes excessive during prolonged procedures
Solution Approach 1:
The system is divided into separate components: a head-mounted display unit and a stationary mount with image recording device. The holding arm with quick release interface allows the display to be separated from the surgeon's head and positioned independently, eliminating the need to carry all system weight on the head during prolonged procedures
Solution Approach 2:
A holding arm with joint and locking mechanism acts as an intermediary between the stationary mount and the display device. This intermediary structure allows the display to be positioned ergonomically while remaining supported by the stationary mount, rather than being worn directly on the head
2Weight of moving object
If a stereoscopic electronic visual display is used instead of head-mounted display, then the weight on the surgeon is reduced, but not all surgeons can recognize three-dimensional images on the display
Solution Approach 1:
The system allows dynamic switching between different viewing modes. The holding arm can be adjusted and locked in different positions, enabling the display to be configured for stereoscopic viewing when needed or repositioned for conventional two-dimensional viewing to accommodate different surgeon capabilities
Solution Approach 2:
The display device serves multiple functions: it can display stereoscopic three-dimensional images for surgeons who can recognize depth, or be repositioned to display conventional two-dimensional images for those who cannot, making the system adaptable to different user needs
3Stability of the object's composition
If the digital stereo image display device is permanently attached to the mount, then the structure is stable, but the device cannot be easily repositioned or removed
Solution Approach 1:
The quick release interface is pre-configured with a locking mechanism that can be quickly engaged or disengaged. This preliminary design allows the attachment to be both stable during use and easily repositioned when needed, without requiring complex tools or procedures
Solution Approach 2:
The attachment system transitions from a static permanent connection to a dynamic configurable connection. The joint in the holding arm combined with the quick release interface allows the device to be firmly attached when locked and easily removed or repositioned when the locking mechanism is engaged

AI summary
A digital stereo image display device has a holding arm which includes a proximal end for attachment to a mount for an optical system with a digital image recording device and which includes a distal end where two digital eyepieces are present and configured to display the images captured by the image recording device from two different viewing angles. An interface part of a quick release interface for releasable attachment to the mount is present at the proximal end. A system includes the digital image display device and a mount. A digital surgical microscope includes the system and a digital image recording device.
