Real-Time Bone Alignment via Marker Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical support technologies cannot determine the appropriate disposition of bones during actual surgery, as they focus on preoperative simulation rather than real-time bone positioning.
Innovation Solution
A surgical operation support system that stores 3D data of target bones and marker position data, captures the marker using an image capturer, and displays the bone alignment based on the captured marker's position, enabling real-time adjustment during surgery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If preoperative simulation software is used to generate 3D bone surface models, then surgical planning can be performed in advance, but real-time bone positioning and alignment during actual surgery cannot be supported
Solution Approach 1:
The system performs preliminary actions by pre-generating 3D bone surface models and calculating optimal bone dispositions before surgery. These pre-calculated models and disposition data are stored and ready for intraoperative use, allowing the surgical plan to be executed rapidly during actual surgery without compromising real-time positioning accuracy
Solution Approach 2:
The system creates a virtual copy of the patient's bone structure through 3D surface modeling from medical images. This digital replica can be manipulated and analyzed preoperatively, and then used as a reference template during surgery to guide actual bone positioning and alignment procedures
2Extent of automation
If marker-based robot attachment control is implemented, then robot positioning is automated, but determination of appropriate bone disposition in living body is not supported
Solution Approach 1:
The system implements feedback by continuously comparing the pre-calculated optimal bone disposition with the actual bone position during surgery. The marker detection system provides real-time position feedback, allowing the system to guide the surgeon in achieving the planned bone alignment while maintaining ease of operation
Solution Approach 2:
The system introduces an intermediary computational layer that translates between the automated robot positioning data and the surgical requirements for bone disposition. This intermediary processing generates visual guides and disposition recommendations that make the complex automated data useful for surgical decision-making
Data Source
AI summary
A system of this invention is directed to a surgical operation support system that supports determination of an appropriate disposition of a bone in a living body during surgery. The surgical operation support system includes a storage that stores 3D data of a first target bone that is one of two divided surgery target bones and 3D data of a reference bone partially overlapping the first target bone in association with position data of a first marker fixed to the first target bone, and stores 3D data of a second target bone that is the other of the two divided surgery target bones in association with position data of a second marker fixed to the second target bone, an image capturer that captures the first marker fixed to the first target bone and the second marker fixed to the second target bone, and a display that changes display in accordance with a change in relative positions of the first marker and the second marker using the data stored in the storage such that the target position of the second marker with respect to the first marker when the second target bone overlaps the reference bone can be grasped.
