Sterile Field Display for Computer-Assisted Surgery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current computer-assisted surgery systems require surgeons to divert their attention from the sterile surgical field to view tracking information, leading to potential errors due to involuntary movements and lack of personalized information display for specific users.
Innovation Solution
A system with a tracking device in the sterile field generating data, a processing device outside the field processing this data, and a sterilized touch-screen displaying device located within the sterile field for wireless interaction, allowing surgeons to view critical information without leaving their focus on the surgical area, with personalized data display based on user role and task.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the displaying device is located outside the sterile field, then the device can be positioned away from the surgical table, but the surgeon must divert attention and move head/sight from the surgical field causing potential errors
Solution Approach 1:
The displaying device is positioned in a different spatial dimension (within the sterile field above the operating table) rather than outside it, allowing surgeons to access information without diverting attention from the surgical field, thus maintaining both accessibility and reliability
2Reliability
If the displaying device is located within the sterile field close to the surgical field, then the surgeon can view information without diverting attention, but the device must be sterilized and integrated into the sterile environment
Solution Approach 1:
A wireless communication system acts as an intermediary between the processing device outside the sterile field and the displaying device within the sterile field, allowing data transmission without physical connection, thus simplifying sterilization requirements while maintaining reliability
3Ease of operation
If the information displayed is the same for everyone, then the system is simple to operate, but the information is not necessarily targeted at a specific task of a specific user
Solution Approach 1:
The information display dynamically adapts to different users and their specific tasks, with the system automatically adjusting the content and presentation based on user identity and current surgical context, thereby achieving personalization without complicating operation
Data Source
AI summary
There is described a system and a method for assisting a user manipulating an object during a surgery, the method comprising: tracking the object in a sterile field in which surgery is being performed at a location using a tracking device which generates tracking data; processing the tracking data using a processing device located outside the sterile field to generate position and orientation information related to the object; and sending the position and orientation information related to the object to a displaying device positioned in the sterile field adjacent to the location at which the surgery is being performed, for display to the user.
