Surgical Camera Position Display for Perspective-Aligned Views
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In surgical procedures involving cameras through access devices, the mismatch between the surgeon's perspective and the camera's view can cause confusion and increase the likelihood of errors due to the unknown camera position relative to the access device's longitudinal axis and mismatched image orientation.
Innovation Solution
Systems and methods for conveying the camera's position to the user, using indicators and transformations to align the camera view display with the user's perspective, allowing for manual or automatic adjustments and providing a common language for communication among surgical team members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a camera is embedded in a channel of an access device or fixed relative to the access device, then the camera can be positioned within the access device to view the surgical site, but the position of the camera relative to the longitudinal axis of the access device is unknown and the image orientation does not match the user's perspective
Solution Approach 1:
The system displays visual indicators showing the camera's position relative to the access device's longitudinal axis and provides feedback to align the displayed image orientation with the user's perspective. The indicator updates in real-time to reflect camera position changes, enabling the user to adjust the access device orientation accordingly.
Solution Approach 2:
A display interface acts as an intermediary between the camera system and the user, translating the camera's physical position into visual indicators and transformed images that convey spatial relationship information. This intermediary layer bridges the gap between the embedded camera and the user's perspective without requiring direct physical adjustment of the camera itself.
2Reliability
If the camera position is not indicated to the user, then the system remains simple, but confusion increases and surgical errors become more likely
Solution Approach 1:
The system uses color-coded indicators to represent different camera positions and orientations relative to the access device. Color changes provide intuitive visual feedback about the camera's spatial relationship, enabling quick assessment of positioning accuracy without complex numerical displays or additional hardware components.
3Ease of operation
If the displayed image orientation does not match the user's perspective, then the camera can be easily installed in the access device, but user confusion and surgical errors increase
Solution Approach 1:
The system creates a transformed copy of the camera image that matches the user's perspective. Rather than physically repositioning the camera or requiring the user to mentally rotate the image, the display system generates a transformed visual copy that aligns with the expected anatomical orientation, reducing cognitive load and potential for error.

AI summary
Camera position indication systems and methods are disclosed herein for conveying a camera's position to a user and/or adjusting a camera view display to match a user's perspective during a surgical procedure. In one embodiment, an example method can include receiving an output view from a camera placed within a channel of an access device to view a surgical site within a patient, receiving an input of camera position from a user, and showing on a display the output view from the camera and an indication of camera position based on the input of camera position.
