Mixed Reality Camera Positioning for Surgical Perspective Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgical joint repair procedures face challenges in accurately positioning and orienting prosthetic implants due to the complexity of matching prosthetic shapes with individual patient bone contours, and in providing effective intraoperative guidance to surgeons.
Innovation Solution
The use of a mixed reality (MR) visualization system that includes MR visualization devices for surgeons and assistants, and an intraoperative guidance system to determine optimal standing locations within the operating room, providing real-time visualizations and image data to enhance surgical precision and teamwork.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional surgical positioning methods are used, then the surgical procedure can be performed with simple equipment, but the precision of prosthetic implant positioning is insufficient
Solution Approach 1:
The patent uses camera devices to capture real-time images of the surgical site and transmits them to remote users. This creates a visual copy of the surgical field, allowing remote users to view the procedure without physically being present. The imaging system captures and transmits visual information, enabling remote observation and guidance while maintaining surgical precision.
Solution Approach 2:
The patent introduces an intraoperative guidance system as an intermediary between the surgeon at the surgical site and remote users. This guidance system includes camera devices, image processing circuits, and communication systems that mediate the interaction between the surgical team and remote observers or experts, enabling precise positioning assistance without direct physical presence.
2Adaptability or versatility
If multiple users are positioned at the surgical site, then comprehensive observation is possible, but the operating room space becomes constrained
Solution Approach 1:
The patent creates visual copies of the surgical field through camera devices that capture images and transmit them to remote users. This allows multiple users to observe the procedure simultaneously from different locations without physically occupying the limited operating room space. The visual replication enables comprehensive observation while preserving physical space.
Solution Approach 2:
The patent transitions the observation dimension from physical presence in three-dimensional space to remote viewing through transmitted images. By moving the observation function to a different dimension (remote digital viewing versus physical proximity), multiple users can observe the surgical site without competing for physical space in the operating room.
3Area of stationary object
If remote users view transmitted images, then operating room space is preserved, but the realism and depth perception of the surgical site is reduced
Solution Approach 1:
The patent transforms the parameters of image transmission by capturing three-dimensional spatial information and transmitting it as visual data that preserves depth and spatial relationships. The system adjusts imaging parameters to maintain realistic representation of the surgical site, enabling remote users to perceive spatial information despite the distance from the actual procedure.

AI summary
Techniques for augmenting a view of a first user of a first mixed reality (MR) visualization device in an operating room are described. For example, an intraoperative guidance system is configured to determine a location for a second user to stand within the operating room. A second MR visualization device is configured to be worn by the second user. The second MR visualization device is further configured to present a MR visualization that indicates the location for the second user to stand within the operating room. The first MR visualization device is configured to present a MR visualization that contains a window that show images of a surgical site captured by a camera supported by the second user.
